Thanks, Craig.Changing The Number Of Oracle Database 12c Log Writers
In an Oracle Database 12c instance you will likely see multiple log writer (LGWR) background processes. When you first start the Oracle instance you will likely see a parent and two redo workers. This is a very big deal and something many of us have been waiting for - for many years!
While I'm excited about the change, if I can't control the number of LGWRs I could easily find myself once again constrained by the lack of LGWRs!
So, my question is how do I manipulate the number of LGWRs from the default. And what is the default based on? It's these types of questions that led me on this quest. I hope you enjoy the read!
Serialization Is Death
Multiple LGWRs is great news because serialization is death to computing performance. Think of it like this. A computer program is essentially lines of code and each line of code takes a little bit of time to execute. A CPU can only process N lines of code per second. This means every serial executing program has a maximum through capability. With a single log writer (LGWR) background process the amount of redo that can be processed is similarly constrained.
An Example Of Serialization Throughput Limitation
Suppose a CPU can process 1000 instructions per millisecond. Also, assume through some research a DBA determined it takes the LGWR 10 instructions to process 10 KB of redo. (I know DBAs who have taken the time to figure this stuff out.) Given these two pieces of data, how many KB of redo can the CPU theoretically process per second?
? KB of redo/sec = (1000 inst / 1 ms)*(10 KB redo / 10 instr)*(1000 ms / 1 sec)* (1 MB / 1000 KB) = 1000 KB redo/sec
This is a best case scenario. As you can see, any sequential process can become a bottleneck. One solution to this problem is to parallelize.
Note: Back in April of 2010 I posted a series of articles about parallelism. If you are interested in this topic, I highly recommend you READ THE POSTS.
Very Cool! Multiple 12c LGWRs... But Still A Limit?
Since serialization is death... and parallelism is life, I was really excited when I saw on my 12c Oracle instance by default it had two redo workers in addition to the "parent" log writer. On my Oracle version 220.127.116.11.2.0 Linux machine this is what I see:
$ ps -eaf|grep prod40 | grep ora_lg
oracle 54964 1 0 14:37 ? 00:00:00 ora_lgwr_prod40
oracle 54968 1 0 14:37 ? 00:00:00 ora_lg00_prod40
oracle 54972 1 0 14:37 ? 00:00:00 ora_lg01_prod40
This is important. While this is good news, unless Oracle or I have the ability to change and increase the number of LGWR redo workers, at some point the two redo workers, will become saturated bringing us back to the same serial LGWR process situation. So, I want and need some control.
Going Back To Only One LGWR
Interestingly, starting in Oracle Database version 18.104.22.168.2.0 there is an instance parameter _use_single_log_writer. I was able to REDUCE the number LGWRs to only one by setting the instance parameter _use_single_log_writer=TRUE. But that's the wrong direction I want to go!
More Redo Workers: "CPU" Instance Parameters
I tried a variety of CPU related instance parameters with no success. Always two redo workers.
More Redo Workers: Set Event...
Using my OSM script listeventcodes.sql I scanned the Oracle events (not wait events) but was unable to find any related Oracle events. Bummer...
More Redo Workers: More Physical CPUs Needed?
While talking to some DBAs about this, one of them mentioned they heard Oracle sets the number of 12c log writers is based on the number of physical CPUs. Not the number CPU cores but the number of physical CPUs. On a Solaris box with 2 physical CPUs (verified using the command, psrinfo -pv) upon startup there was still on two redo workers.
$ psrinfo -p
$ psrinfo -pv
The physical processor has 1 virtual processor (0)
UltraSPARC-III (portid 0 impl 0x14 ver 0x3e clock 900 MHz)
The physical processor has 1 virtual processor (1)
UltraSPARC-III (portid 1 impl 0x14 ver 0x3e clock 900 MHz)
More Redo Workers: Adaptive Behavior?
Looking closely at the Solaris LGWR trace file I repeatedly saw this:
Created 2 redo writer workers (2 groups of 1 each)
kcrfw_slave_adaptive_updatemode: scalable->single group0=375 all=384 delay=144 r
*** 2014-12-08 11:33:39.201
Adaptive scalable LGWR disabling workers

*** 2014-12-08 15:54:10.972

*** 2014-12-08 22:01:42.176
Adaptive scalable LGWR disabling workers
It looks to me like Oracle has programed in some sweeeeet logic to adapt the numbers of redo workers based the redo load.
So I created six Oracle sessions that simply inserted rows into a table and ran all six at the same time. But it made no difference in the number of redo workers. No increase or decrease or anything! I let this dml load run for around five minutes. Perhaps that wasn't long enough, the load was not what Oracle was looking for or something else. But the number of redo workers always remained at two.
Summary & Conclusions
It appears at instance startup the default number of Oracle Database 12c redo workers is two. It also appears that Oracle has either already built or is building the ability for Oracle to adapt to changing redo activity by enabling and disabling redo workers. Perhaps the number of physical CPUs (not CPU cores but physical CPUs) plays a part in this algorithm.
While this was not my research objective, I did discover a way to set the number of redo workers back to the traditional single LGWR background process.
While I enjoyed doing the research for this article, it was disappointing that I was unable to influence Oracle to increase the number of redo workers. I sure hope Oracle either gives me control or the adaptive behavior actually works. If not, two redo workers won't be enough for many Oracle systems.
All the best in your Oracle performance endeavors!
We often encounter situations when a SQL runs optimally when it is hinted but sub-optimally otherwise. We can use hints to get the desired plan but it is not desirable to use hints in production code as the use of hints involves extra code that must be managed, checked, and controlled with every Oracle patch or upgrade. Moreover, hints freeze the execution plan so that you will not be able to benefit from a possibly better plan in future.
So how can we make such queries use optimal plan until a provably better plan comes along without adding hints?
Well, the answer is to use SQL Plan Management which ensures that you get the desirable plan which will evolve over time as optimizer discovers better ones.
To demonstrate the procedure, I have created two tables CUSTOMER and PRODUCT having CUST_ID and PROD_ID respectively as primary keys. PROD_ID column in CUSTOMER table is the foreign key and is indexed.
SQL>onn hr/hr drop table customer purge; drop table product purge; create table product(prod_id number primary key, prod_name char(100)); create table customer(cust_id number primary key, cust_name char(100), prod_id number references product(prod_id)); create index cust_idx on customer(prod_id); insert into product select rownum, 'prod'||rownum from all_objects; insert into customer select rownum, 'cust'||rownum, prod_id from product; update customer set prod_id = 1000 where prod_id > 1000; exec dbms_stats.gather_table_stats (USER, 'customer', cascade=> true); exec dbms_stats.gather_table_stats (USER, 'product', cascade=> true);
– First, let’s have a look at the undesirable plan which does not use the index on PROD_ID column of CUSTOMER table.
SQL>conn / as sysdba alter system flush shared_pool; conn hr/hr variable prod_id number exec :prod_id := 1000 select cust_name, prod_name from customer c, product p where c.prod_id = p.prod_id and c.prod_id = :prod_id; select * from table (dbms_xplan.display_cursor()); PLAN_TABLE_OUTPUT ----------------------------------------------------------------------SQL_ID b257apghf1a8h, child number 0 ------------------------------------- select cust_name, prod_name from customer c, product p where c.prod_id = p.prod_id and c.prod_id = :prod_id Plan hash value: 3134146364 ---------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | ---------------------------------------------------------------------- | 0 | SELECT STATEMENT | | | | 412 (100)| | | 1 | NESTED LOOPS | | 88734 | 17M| 412 (1)| 00:00:01 | | 2 | TABLE ACCESS BY INDEX ROWID| PRODUCT | 1 | 106 | 2 (0)| 00:00:01 | |* 3 | INDEX UNIQUE SCAN | SYS_C0010600 | 1 | | 1 (0)| 00:00:01 | |* 4 | TABLE ACCESS FULL | CUSTOMER | 88734 | 9098K| 410 (1)| 00:00:01 | ----------------------------------------------------------------------
– Load undesirable plan into baseline to establish a SQL plan baseline for this query into which the desired plan will be loaded later
SQL>variable cnt number exec :cnt := dbms_spm.load_plans_from_cursor_cache(sql_id => 'b257apghf1a8h'); col sql_text for a35 word_wrapped col enabled for a15 select sql_text, sql_handle, plan_name, enabled from dba_sql_plan_baselines where sql_text like 'select cust_name, prod_name%'; SQL_TEXT SQL_HANDLE PLAN_NAME ENABLED ----------------------------------- ---------------------------------------------------------------------- select cust_name, prod_name SQL_7d3369334b24a117 SQL_PLAN_7ucv96d5k988rfe19664b YES
– Disable undesirable plan so that this plan will not be used
SQL>variable cnt number exec :cnt := dbms_spm.alter_sql_plan_baseline (- SQL_HANDLE => 'SQL_7d3369334b24a117',- PLAN_NAME => 'SQL_PLAN_7ucv96d5k988rfe19664b',- ATTRIBUTE_NAME => 'enabled',- ATTRIBUTE_VALUE => 'NO'); col sql_text for a35 word_wrapped col enabled for a15 select sql_text, sql_handle, plan_name, enabled from dba_sql_plan_baselines where sql_text like 'select cust_name, prod_name%'; SQL_TEXT SQL_HANDLE PLAN_NAME ENABLED ----------------------------------------------------------------------select cust_name, prod_name SQL_7d3369334b24a117 SQL_PLAN_7ucv96d5k988rfe19664b NO
– Now we use hint in the above SQL to generate the optimal plan which uses index on PROD_ID column of CUSTOMER table
SQL>conn hr/hr variable prod_id number exec :prod_id := 1000 select /*+ index(c)*/ cust_name, prod_name from customer c, product p where c.prod_id = p.prod_id and c.prod_id = :prod_id; select * from table (dbms_xplan.display_cursor()); PLAN_TABLE_OUTPUT ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ SQL_ID 5x2y12dzacv7w, child number 0 ------------------------------------- select /*+ index(c)*/ cust_name, prod_name from customer c, product p where c.prod_id = p.prod_id and c.prod_id = :prod_id Plan hash value: 4263155932 ----------------------------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | ----------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | | | 1618 (100)| | | 1 | NESTED LOOPS | | 88734 | 17M| 1618 (1)| 00:00:01 | | 2 | TABLE ACCESS BY INDEX ROWID | PRODUCT | 1 | 106 | 2 (0)| 00:00:01 | |* 3 | INDEX UNIQUE SCAN | SYS_C0010600 | 1 | | 1 (0)| 00:00:01 | |* 4 | TABLE ACCESS BY INDEX ROWID BATCHED| CUSTOMER | 88734 | 9098K| 1616 (1)| 00:00:01 | | 5 | INDEX FULL SCAN | SYS_C0010601 | 89769 | | 169 (0)| 00:00:01 | -----------------------------------------------------------------------------------------------------
– Now we will load the hinted plan into baseline –
– Note that we have SQL_ID and PLAN_HASH_VALUE of the hinted statement and SQL_HANDLE for the unhinted statement i.e. we are associating hinted plan with unhinted statement.
SQL>variable cnt number exec :cnt := dbms_spm.load_plans_from_cursor_cache(- sql_id => '5x2y12dzacv7w', - plan_hash_value => 4263155932, - sql_handle => 'SQL_7d3369334b24a117');
– Verify that there are now two plans loaded for that SQL statement:
- Unhinted sub-optimal plan is disabled
- Hinted optimal plan which even though is for a “different query,” can work with earlier unhinted query (SQL_HANDLE is same) is enabled.
SQL>col sql_text for a35 word_wrapped col enabled for a15 select sql_text, sql_handle, plan_name, enabled from dba_sql_plan_baselines where sql_text like 'select cust_name, prod_name%'; SQL_TEXT SQL_HANDLE PLAN_NAME ENABLED ---------------------------------------------------------------------- select cust_name, prod_name SQL_7d3369334b24a117 SQL_PLAN_7ucv96d5k988rea320380 YES select cust_name, prod_name SQL_7d3369334b24a117 SQL_PLAN_7ucv96d5k988rfe19664b NO
– Verify that hinted plan is used even though we do not use hint in the query –
– The note confirms that baseline has been used for this statement
SQL>variable prod_id number exec :prod_id := 1000 select cust_name, prod_name from customer c, product p where c.prod_id = p.prod_id and c.prod_id = :prod_id; select * from table (dbms_xplan.display_cursor()); PLAN_TABLE_OUTPUT ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ SQL_ID b257apghf1a8h, child number 0 ------------------------------------- select cust_name, prod_name from customer c, product p where c.prod_id = p.prod_id and c.prod_id = :prod_id Plan hash value: 4263155932 ----------------------------------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | ----------------------------------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | | | 1618 (100)| | | 1 | NESTED LOOPS | | 88734 | 17M| 1618 (1)| 00:00:01 | | 2 | TABLE ACCESS BY INDEX ROWID | PRODUCT | 1 | 106 | 2 (0)| 00:00:01 | |* 3 | INDEX UNIQUE SCAN | SYS_C0010600 | 1 | | 1 (0)| 00:00:01 | |* 4 | TABLE ACCESS BY INDEX ROWID BATCHED| CUSTOMER | 88734 | 9098K| 1616 (1)| 00:00:01 | | 5 | INDEX FULL SCAN | SYS_C0010601 | 89769 | | 169 (0)| 00:00:01 | ----------------------------------------------------------------------------------------------------- Predicate Information (identified by operation id): --------------------------------------------------- 3 - access("P"."PROD_ID"=:PROD_ID) 4 - filter("C"."PROD_ID"=:PROD_ID) Note ----- - SQL plan baseline SQL_PLAN_7ucv96d5k988rea320380 used for this statement
With this baseline solution, you need not employ permanent hints the production code and hence no upgrade issues. Moreover, the plan will evolve with time as optimizer discovers better ones.
Note: Using this method, you can swap the plan for only a query which is fundamentally same i.e. you should get the desirable plan by adding hints, modifying an optimizer setting, playing around with statistics etc. and then associate sub-optimally performing statement with the optimal plan.
I hope this post was useful.

hyundai santa fe 2015 caracteristicas might likewise be furnished with this area's foreseen alternatives, including a third-column seat and a route machine. supporters might moreover browse styles with considered one of two V6 motors, door or all-wheel force and a handbook or modernized transmission. lamentably, that you can't actually mix'n'match - base styles have a more modest V6 with less strength, and various the limited's alleviation and solace alternatives are restrictive to that trim.
in general, despite the fact that, the 2015 hyundai santa fe sport review is a brilliant plausibility for youthful families needing all-capacity transportation. We wouldn't guide it if energetic driving progress are favored. The more diminutive Mazda CX-7 and Mitsubishi Outlander, and additionally the average size Nissan Murano would all be most well known for this situation, and Toyota's Highlander is roomier and speedier. yet in the event that you require different hybrid for the cash, the Hyundai Santa Fe is sensibly convincing.
2015 hyundai santa fe sportThe when will the 2015 hyundai santa fe be available medium size hybrid action utility is accessible in three trim extents: base GLS, SE and limited. The GLS begins off with sixteen-inch compound wheels, full power supplies, keyless section, journey direct and a six-speaker sound machine with a CD/Mp3 player, satellite radio, an assistant sound jack and a USB port. The midlevel SE trim joins a finer V6 motor, 18-inch amalgam wheels, an auto-darkening rearview mirror, robotized headlights, a drive pc and direction wheel-snared sound controls. The best Santa Fe constrained includes a sunroof, cowhide based upholstery, warmed front seats, a force driver seat, twin-zone programmed nearby climate control and a top rate Infinity sound contraption with a six-CD changer.
one of the vital restricted's additional features are offered as options on the GLS and SE. different options include a third-row seat with auxiliary rear local weather controls and Bluetooth for wirelessly connecting your phone to the auto. A towing training bundle is same old on SE and limited fashions, and an not obligatory navigation device and a rear-seat leisure system are offered on the Santa Fe limited only.
hyundai santa fe 2015 price
In GLS trim, the Santa Fe comes with a 2.7-liter V6 that produces 185 horsepower and 183 pound-feet of torque. The SE and limited function a larger three.3-liter V6 excellent for 242 hp and 226 lb-feet of torque. A five-velocity guide transmission is same old with the bottom engine, and a 4-speed automatic is not obligatory. The greater V6 comes same old with a 5-speed automated transmission and accelerates the when is the 2015 hyundai santa fe release date from zero to 60 mph in 8.7 seconds.
All hyundai santa fe 2015 fashions are provided with both front-wheel-pressure or all-wheel-drive powertrains. The electronically controlled AWD gadget routinely routes energy to the wheels with the perfect traction. For more suitable performance in slippery or off-street stipulations, a driver-selectable AWD lock offers a fixed 50/50 torque split between the front and rear wheels.
correctly equipped, the Santa Fe can tow up to three,500 pounds. EPA estimated fuel economic system is pretty much an identical for both engines: An AWD variation with the 3.three-liter V6 has scores of 17 mpg city/24 mpg highway and 19 mpg blended, a tad above reasonable for this phase.
2015 hyundai santa fe mpgThe 2015 hyundai santa fe limited offers an impressive array of same old safety options together with antilock disc brakes, traction keep watch over, steadiness keep watch over, front-seat facet airbags, full-length head curtain airbags and lively front-seat head restraints.
In executive crash exams, the hyundai santa fe 2015 philippines got an excellent 5 stars for defense in frontal and side influences. In insurance Institute for highway safety testing, the nuevo hyundai santa fe 2015 earned the absolute best imaginable rating of "excellent" in each frontal-offset and aspect-influence assessments.
2015 hyundai santa fe sport Release DateThis second-technology Santa Fe has a lovely dashboard and high quality supplies during. In restricted trim, the convincing faux timber and aluminum accents give the crossover a certain luxurious feel. Blue instrument lighting fixtures and an non-compulsory 10-speaker Infinity sound machine handiest add to the Santa Fe's plush inside ambience.
The using position can be awkward for some, although, because the front seats are established overly high and the short bottom cushions supply minimal thigh fortify for taller adults.
With the optional third-row seat, the Santa Fe can accommodate up to seven passengers. Like most models in this segment, alternatively, the third row is truly best suitable for kids. The second row is notably above average in relation to alleviation. The cut up rear seats can be folded flat in each rows, and the Santa Fe splits the variation between smaller and larger crossover SUVs with seventy eight cubic ft of most cargo room.
hyundai santa fe 2015 model
Smaller crossover SUVs just like the Mazda CX-7 and Mitsubishi Outlander are sportier and extra worthwhile to force arduous, although the Santa Fe's handling is indisputably composed and might in reality be enjoyable every now and then. The trade-off is that the trip may also be very busy on the highway on fashions with the larger wheels. during standard using, the brake pedal feels about proper, however can get smooth all through onerous braking.
the 2.7-liter V6 gives first rate acceleration, however the additional kick and subtle nature of the three.three-liter V6, which is sort of as gas environment friendly, is important and gives the when does the 2015 hyundai santa fe come out a extra large feel. In testing, although, now we have discovered the greater V6's 5-velocity computerized can on occasion be sluggish to downshift for quick passing or merging maneuvers.
its a well known fact that the Cadillac other individuals have pointed the back wheel-drive 2015 cadillac escalade platinumsoundly at the balanced BMW 3 succession, which has laid out the portion for a considerable length of time. The 2015 cadillac fleetwood price outside measurements principally recreate those of the 3 accumulation, and the 2015 cadillac escalade redesign bargains pleasant develop quality, feisty effectiveness and an including weight together with a supple ride, much the same as the benchmark Bimmer. Cadillac's most up to date form likewise bargains an intelligent electronic interface with which to work all the nearby inside solace doohickeys, which is a vital component in this section of lavish cars.
The 2015 cadillac escalade first drive stacks up well against its opponent. On the expressway, it supplies great direction feel and a light-footed, shrewdly adjusted ride. Helping the sharp elements is reality that this Caddy is the lightest car in its classification (by utilizing 70-150 pounds, contingent upon trim). further adding to the ATS's physicality is its best 50/50 weight circulation between the passageway and back wheels.
With a trio of motor decisions close by, the 2015 cadillac hybrid productivity ranges from lukewarm to intriguing. the base 2.5-liter 4 serves as the expense and gas financial framework pioneer, actually assuming its 202-drive yield slacks in the again of the base motors found in the opposition. in the mean time, the turbocharged 2.0-liter inline-4 packs a superb midrange punch and is the main alternative inside the ATS extend that might be had with a manual gearbox. With 321 hp, the vivacious V6 offers a sweet soundtrack and is intelligently matched to a dreadfully responsive computerized transmission.
There are various minor contemplations with the ATS. aficionados may requirement for a handbook gearbox with the top motor, while the back seats and trunk are substantially less spacious than what a few adversaries give. indeed, this stage isn't exactly dispossessed of ability, either. The 2013 BMW three grouping still takes high respects by utilizing goodness of its progressed base powertrain and much more alluring driving flow, in any case it is normally ordinarily dearer. We're furthermore marginally partial to the correspondingly intelligently adjusted Audi A4, the refined Mercedes-Benz C-class and cost stuffed - if no more as cleaned - Infiniti G vehicle. however general, the 2013 Cadillac ATS is an extremely solid contender in the, exceptionally aggressive segment of reduced diversion vehicles.
2015 cadillac escalade premium
The 2015 cadillac escalade hp is a five-traveler, extravagance situated action vehicle that is given in four trim extents: base, sumptuous, productivity and top rate.
standard gimmicks on the bottom trim incorporate 17-inch combination wheels, warmed mirrors, mechanized headlights, journey control, twin-zone programmed atmosphere manage, six-way vitality front seats with vitality lumbar, leatherette premium vinyl upholstery, a tilt-and-extendable direction wheel, Onstar, Bluetooth telephone network and a seven-speaker Bose sound framework with satellite radio, an ipod/USB interface and an assistant sound jack.
the luxurious trim gives run-level tires, keyless entrance/ignition, far flung motor begin, eight-methodology force doorway seats, front and back park support, a rearview computerized cam, an auto-darkening rearview imitate, calfskin seating, driver memory works, a 60/forty part collapsing back seat (with move-thru), HD radio, Bluetooth sound streaming and the CUE infotainment interface.
The proficiency trim (no more accessible with 2.5-liter motor) further gives twin fumes outlets, a Driver cognizance bundle arrangement (forward crash caution, back cross-site guests alarm, path takeoff cautioning, programmed wipers and back seat feature airbags), a vivacious air grille, xenon headlights, an overhauled 10-speaker Bose encompass sound gadget (with a CD member), door action seats (with driver-aspect support change) and a set back seat with pass-through.
Stepping as much as the top class trim (not on hand with 2.5-liter engine) adds 18-inch wheels, a navigation machine, a color head-up display and the 60/forty cut up-folding rear seat. An 2015 cadillac escalade images top rate with rear-wheel force additionally comes with summer tires, a sport-tuned suspension, adaptive suspension dampers and a limited-slip rear differential.
among the features which can be usual for the upper trim ranges are to be had as options on the lower trims. just a few other not obligatory applications are also available. the driving force help package includes the features from the awareness package deal and provides adaptive cruise keep watch over, blind-spot monitoring, collision education with brake help, and the colour head-up show. The cold climate bundle contains heated entrance seats and a heated guidance wheel. The monitor performance bundle provides an engine oil cooler and upgraded brake pads. other options embrace totally different wheels, a sunroof and a trunk cargo organizer.
when will the 2015 cadillac escalade be available
the 2.5 fashions include a 2.5-liter 4-cylinder engine that produces 202 hp and one hundred ninety pound-toes of torque. the 2.0 Turbo fashions include a turbocharged 2.0-liter 4-cylinder rated at 272 hp and 260 lb-feet of torque. the 3.6 fashions include a three.6-liter V6 that cranks out 321 hp and 274 lb-feet of torque.
All 2015 cadillac escalade jalopnik engines come matched to a six-pace computerized transmission aside from the two.0 Turbo, which can also be had with a six-velocity handbook. Rear-wheel drive is standard across the board, with all-wheel power optional for the 2.zero- and 3.6-liter engines.
In Edmunds checking out, a rear-force ATS 2.0T with the manual went from zero to 60 mph in 6.3 seconds. A rear-drive ATS 3.6 top class with an automated accelerated from zero to 60 mph in 5.7 seconds. each times are reasonable among in a similar fashion powered entry-stage activity sedans.
EPA-estimated gasoline financial system for the ATS 2.5 stands at 22 mpg city/33 mpg freeway and 26 mpg blended. The V6 is estimated to succeed in 19/28/26 with rear-wheel power and Cadillac claims the two.zero-liter Turbo will get the same with an automatic transmission. With all-wheel power, the ATS V6 drops to 18/26/21.

standard safety features for the new 2015 cadillac escalade for sale embody antilock disc brakes, traction regulate, balance keep an eye on, energetic front head restraints, front-seat aspect and knee airbags and entire-size aspect curtain airbags. additionally usual is OnStar, which includes automated crash notification, on-demand roadside help, far off door unlocking, stolen vehicle assistance and switch-with the aid of-turn navigation. non-compulsory are the aforementioned Driver consciousness and Driver assistance applications.
In Edmunds brake testing, an ATS 3.6 premium got here to a stop from 60 mph in an impressively short 108 feet. A 2.0T stopped in an ordinary distance of 113 feet.
2015 cadillac deville price
within its cabin, the photos of 2015 cadillac escalade boasts plenty of top quality materials, together with tasteful timber and steel accents. The on hand CUE infotainment interface features huge icons and operates like an iPhone or iPad, which is to say you use it by tapping, flicking, swiping or spreading your fingers -- making it familiar for a lot of users. moreover, "Haptic" comments allows you to understand while you've pressed a virtual button by using pulsing when you contact it.
Up front, the seats do a pleasant job of protecting one in situation right through spirited drives, and it is quite straightforward to find a comfortable riding position. Oddly, the not obligatory game seats do not present rather more in the best way of lateral enhance for the motive force, despite their energy-adjustable bolsters.
Rear-seat headroom is good, but knee room is tight for taller people. regardless of a wide opening, the 2015 cadillac escalade length trunk deals just 10.2 cubic ft of capability — downright stingy for this phase. fortuitously, some trims function a 60/forty split-folding rear seat, which helps on this regard.

The 2015 cadillac escalade vs infiniti qx80 is an impressive all-around performer, because of a poised experience, sure-footed cornering functionality and superb response from the guidance and brakes. the two.5-liter engine is smooth, however it offers tepid acceleration compared to other entry-stage powertrains, notably that of the BMW 328i. opt for one of the crucial different ATS engines, then again, and you can have no complaint, as they supply thrust extra in line with this Cadillac's athletic personality. even supposing fans could lament the lack of a guide transmission for the V6, the six-pace automated is tricky to fault. Switched to game mode, this automated is aware of just when to hold a equipment and provides smooth, rev-matched downshifts right on time, each time.
Even with its wearing calibration, the cadillac new models 2015 takes neglected city streets in stride, absorbing the shock of potholes and damaged pavement with out upsetting the automobile or its occupants. because of this, the compact Cadillac makes for a nice day by day driver that can also provide a whole lot of leisure on a Sunday morning power.
the new 6 demonstrates that Mazda wasn't going to make the identical mistake twice. want room to chill out? It bargains one of the vital accommodating cabins of any midsize sedan, with Texas-sized front seats and a backseat match for 6-footers. acquired baggage, or in all probability 4 units of golf golf equipment? The midsize Mazda now options an impressively massive 16.6 cubic toes of trunk space. need energy? Mazda's received you covered with the biggest and strongest V6 on this worth bracket, though its gasoline financial system is disappointing. need to make a way commentary? then you definately shouldn't be shopping for a family sedan within the first position. but as such cars go, we think the brand new 6 manages to be tautly horny, in particular from the front, despite its additional 6.1 inches of length and 2.three inches of width. in contrast to the previous model, the 2016 Mazda6 Interior Review used to be engineered namely for the North American market -- and it shows.
It additionally method introduced weight, as the enlarged 6 is roughly a hundred and fifty pounds heavier than its predecessor. yet you can nonetheless discover the sporty reflexes that consumers have come to expect from this efficiency-oriented brand. physique roll is minimal through domestic-sedan requirements, and the steerage is light however responsive. The 6 by no means allows you to omit its really extensive dimension, but its smartly-sorted chassis and light-on-its-ft character at pace places it 2nd most effective to the Nissan Altima within the fun-to-force category.
Wait a minute, you might be announcing -- how might the "zoom-zoom" household sedan fail to be the sportiest automobile in its class? Three causes: The Altima's significantly lighter, its physique motions are higher managed and its steering is tighter and more communicative. however so what? because the previous 6 validated (and the Toyota Camry continues to reveal), prime-notch riding dynamics don't a very best-promoting household sedan make. What the brand new 6 offers is the coveted combination of american-fashion measurement and energy, along with above-average handling for individuals who care about that kind of thing. authentic fans won't in finding the 6 to their liking -- however hiya, that is what the Mazdaspeed three is for.
in short, the 2009 Mazda 6 is at or close to the top of its class in most respects. As universal, although, we suggest check-riding as many rival models as conceivable earlier than making your resolution, including the Chevrolet Malibu, Honda Accord, Hyundai Sonata, Nissan Altima, Subaru Legacy and Toyota Camry. each has its own strengths and weaknesses, but few can suit the 6's all-round competence and attraction.

Antilock disc brakes, balance control, front-seat facet airbags and entire-length facet curtain airbags are all same old on the aftermarket mazda 6 parts.
difference between mazda 3 and mazda 6
The mazda 6 bluetooth issues control structure is in most cases intuitive, with all major knobs and buttons naturally labeled and simply manipulated. it's sexy, too, with crimson backlighting for the gauges and a swish middle stack sweeping ahead towards the windshield, despite the fact that the atypical black-and-silver patterned plastic trim in journeying models and above is not going to strike everyone's fancy. materials high quality is hit-or-pass over, as the wealthy-feeling soft-contact subject material on the passenger side of the dashboard contrasts with low-cost arduous stuff on the driving force aspect. The emergency brake additionally feels a bit chintzy for this value point. The generously proportioned seats are somewhat at ease, then again, with abundant leg- and headroom all around. On the downside, energy-adjustable lumbar beef up is unavailable, and the not obligatory manually adjustable driver-facet lumbar toughen operates by the use of a labor-intensive knob.
in the audio department, the 6's usual stereo is just enough, and while the optional Bose gadget sounds markedly better, it lacks the clarity and wealthy bass response of the best stereos on this category. there may be better information on the cargo-carrying entrance, the place the sixteen.6-cubic-foot trunk units a new same old for domestic sedans. furthermore, it can be more desirable with the aid of upscale strut helps that do not impinge on the cargo area, and the 60/40-cut up-folding rear seats add to the 6's impressive hauling capabilities.

A awesome quantity of highway noise filters into the 6's cabin at velocity. Pavement imperfections barely ruffle the 6's composure, although, even when it is equipped with the non-compulsory 18-inch wheels. the bottom 2.5-liter engine produces wheezy noises and tepid acceleration, though the slick-shifting six-speed handbook shifter livens things up a little. The 5-pace automated is much less engaging but offers remarkably refined shifts. the large 3.7-liter V6 feels and sounds muscular, but it's a clean operator, even at greater engine speeds. unluckily, the six-pace computerized is not tuned for enthusiastic using -- downshifts are delayed, even in guide mode. handling is spectacular for a big household sedan, however the 6 would not really feel as tossable in corners as the Altima, and its guidance is lighter and looser than the nimble Nissan's. there may be most likely sufficient zoom on this chassis to placate folks that like to pressure, whereas the average client will relish the 6's reasonably compliant journey.

The minimal 5-entryway hatchback contends with a climbing workforce of minicars that gimmicks the MINI Cooper that dispatched the stage inside the U.s., the new Fiat 500, the Mitsubishi i electrical auto, and a couple of two-seat passages, the developing old savvy Fortwo and the new Scion iq.
actually assuming its 12-foot-1-inch length is unequivocally three toes shorter than a Chevrolet Cruze smaller 4-entryway vehicle, the Spark does not so much show up as little as it seems to be. best in scale- -stopped beside an amusement utility auto, as a sample -is its fitting measurement prominent.
The creators have accomplished all that they may to blanket the Spark's extents. its a tall auto roosted on little 15-inch wheels, however stress strains, dark plastic boards that proceed with the window line, and a vast Chevy twin-opening grille help to conceal the chunk sided, scorn nosed field-on-wheels show up.
The handles for the back entryways are stowed away operating at a profit plastic trim, which Chevy says gives the auto a "roadster like" appear. we don't in all actuality buy that, however outwardly the back entryways don't fundamentally learn as entryways on first look. while the back completion is everything except vertical, a long top spoiler stretches out to edge the back window opening, offering profundity to the back and bettering the Spark's aeromechanics too.
inside, the textured hard-plastic dash makes no attempt and camouflage what its through copying another topic. so also, the seats are unashamedly manufactured material. however constitution color embeds on the entryway trim, inside the entryway boxes, and on the dashboard include a sprightly stress. They take notice the painted inside steel found in economy autos of the Sixties, despite the fact that inside the Spark they may be all body-color plastic presented for effect.
Like its vast sibling the Sonic, the Spark has a "motorbike model" instrument case mounted on the direction section. It suits a speedometer and a little auto learning show. the base Spark has a little monochrome center showcase, yet all LT trim levels work a 7-inch coloration touchscreen show inside the heart stack.
there is only one motor in the Spark, a 84-pull 1.2-liter four-barrel Ecotec that puts out eighty three lb-toes of torque. The Spark comes same old with a five-velocity handbook gearbox, and a four-pace automated transmission will likewise be requested for an extra $925. Forceful driving with the aide can hustle the little Spark by means of town acceptably, however the robotized is, honestly, a puppy. Its first gear is inordinate sufficient that quickening a long way from stoplights shows up excruciatingly steady, and it would not appear to offer such a great amount of punch at any velocity or in any apparatuses. this is one auto for which the handbook gearbox may be the main conceivable choice.
The 2013 Chevrolet Spark lt for sale with the aide transmission is EPA-evaluated at 32 mpg city, 38 mpg thruway, for a blended score of 34 mpg- -comparable to the rest inside the class, however sensibly lower than a considerable amount of bigger reduced vehicles, which benefit from higher the study of air. the programmed model is accessible in lower, at a consolidated 32 mpg (28 mpg city, 37 mpg road). The Spark runs on consistent evaluation gas, in spite of the fact that; the Fiat 500 prescribes top rate gas.
The Spark's ride is somewhat firm, by and by it dealt with broken NY city roads with aplomb- -despite the fact that riders had been mindful of each knock, pothole, edge, and swell. its tall enough that travelers will truly feel the Spark inclining toward difficult corners, nonetheless its reasonably little wheels and tires toiled grave to convey the road. the electric force direction deals some interstate feel, and though its barely ever as charming to throw round as the MINI Cooper, the Spark can trade paths into spaces diverse autos couldn't fit into, and it is a delight to stop. Our starting force provided for us no probability to test the Spark at 75-mph turnpike speeds.
within, the Spark's seats are physically movable yet agreeable -if a tad bit thin for broad channeled American travelers. The back seatback is upright, yet with to some degree arrangement between front- and once more seat riders, four adult male people can possess the Spark and go in reasonable house. that is more than can additionally be expressed for the MINI Cooper or Fiat 500, actually assuming the Mitsubishi i electric auto -the main other 5-entryway hatchback on this arrangement -bargains also shocking back seat space too.
With the back seat up, the Spark has 11.four cubic feet of load territory -enough to hold 10 to 12 full paper staple gear without issues -which grows to 31.2 cubic toes when the 60/40 part back seat is flipped and collapsed down. A payload net is close by as a feature of the higher trim levels, as are rails to mount baggage bearers on the top.
The 2013 Chevrolet Spark lt for sale has been intended to satisfy all present and future U.s. security necessities, and springs ordinary and not utilizing a less than 10 airbags. It has now not yet been appraised for accident wellbeing by method for either the NHTSA or IIHS. The Spark has not least complex electronic dependability keep watch over and electronically monitored slowing mechanisms, yet moreover doorway seat-cinch pretensioners and same old Hill start help- -a decent trademark for youthful drivers. Outward innovative and insightful is great, together with respectable back three-quarter perceivability over the intention energy's shoulder for switching (no back creative and judicious Polaroid is possible). All Sparks come standard with GM's Onstar gadget and 6 free months of bearer.
quickly for a minicar, all Sparks come typical with air-con, vitality windows, a back window wiper, and a drive pc. Furthermore Chevy contemplated that one methodology to make the Spark appear to be considerably less machine like
The Passport was once actually a re-badged Isuzu Rodeo, a truck-based SUV inbuilt Indiana, at a plant that Subaru and Isuzu shared on the time. the primary era Passport, sold from 1994 via 1997, offered a collection of a one hundred twenty-horsepower 2.6-liter four-cylinder engine, paired with a 5-pace handbook gearbox, or a a hundred seventy five-hp 3.2-liter V-6--and an available four-pace automated transmission.

In some cases, the damage was once so extreme that Honda simply repurchased the autos from their homeowners. Used-automotive shoppers taking a look at Passports must be sure to in finding out whether the car had been via a remember, and what--if anything else--was achieved.

Interesting info-graphics on Data-center / DB-Manageability
One of the key task that a DBA performs repeatedly is Provisioning of Databases which also happens to one of the top 10 Database Challenges as per IOUG Survey .
Most of the challenge comes in form of either Lack of Standardization or it being a Long and Error Prone Process . This is where Enterprise Manager 12c can help by making this a standardized process using profiles and lock-downs ; plus have a role and access separation where lead dba can lock certain properties of database (like character-set or Oracle Home location or SGA etc) and junior DBA's can't change those during provisioning .Below image describes the solution :
In Short :
- Its Fast
- Its Easy
- And you have complete control over the lifecycle of your dev and production resources.
I actually wanted to show step by step details on how to provision a 11204 RAC using Provisioning feature of DBLM , but today i saw a great post by MaaZ Anjum that does the same , so i am going to refer you to his blog here :

A quick note on how to install EMCLI which is used for various CLI operations from EM . I was looking to test some Database provisioning automation via EMCLI and thus was looking to setup the same .
To set up EMCLI on the host, follow these steps:
1. Download the emcliadvancedkit.jar from the OMS using URL https://<omshost>:<omsport>/em/public_lib_download/emcli/kit/emcliadvancedkit.jar
2. Set your JAVA_HOME environment variable and ensure that it is part of your PATH. You must be running Java 1.6.0_43 or greater. For example:
o setenv JAVA_HOME /usr/local/packages/j2sdk
o setenv PATH $JAVA_HOME/bin:$PATH
3. You can install the EMCLI with scripting option in any directory either on the same machine on which the OMS is running or on any machine on your network (download the emcliadvancedkit.jar to that machine)
java -jar emcliadvancedkit.jar client -install_dir=<emcli client dir>
4. Run emcli help sync from the EMCLI Home (the directory where you have installed emcli) for instructions on how to use the "sync" verb to configure the client for a particular OMS.
5. Navigate to the Setup menu then the Command Line Interface. See the Enterprise Manager Command Line Tools Download page for details on setting EMCLI.
