Ok Folks, I’ve been here are Oracle Open World for a few days now. In that time, I’ve had numerous conversations about running Oracle Enterprise Manager 12c on Oracle Database 12c. I will be honest and say that I’ve enjoyed these conversations; however, after about the fourth time I decided I need to write a quick post on the explanation discussed in these conversations.
Early this year (August) I wrote a post about the what came out of the OEM CAB in May 2014 and how to get OEM 12c to work on DB12c. The concept of running OEM 12c on DB12c, pluggable or not, have many people excited and looking forward to configuring OEM to do that very configuration. Heck, I’ve even installed it for a few customers in that configuration (non-PDB). So I’m a bit sad in having to say this: ORACLE DATABASE 12c SUPPORT FOR THE REPOSITORY DATABASE IS TEMPORARILY SUSPENDED! I say this due to the My Oracle Support (MOS) Note: 1920632.1.
Note 1920632.1 states the following:
Due to some recently discovered scenarios, we (Oracle) are temporarily suspending the certification of DB 184.108.40.206 and DB 220.127.116.11 as a Certified Repository version for EM 12c R4 until additional testing is complete.
Now what does this mean for those customers and clients that have already built their OEM 12c repository on DB 12c (18.104.22.168 or 22.214.171.124)? The MOS note outlines what to do in the action section of the note:
Until testing is complete on the 12c Database, Oracle recommends using DB 126.96.36.199 as the EM 12c R4 Repository.
If you are currently running a 12c DB repository, please be aware that additional testing is underway and there are currently no bugs or patches required; but if testing proves a patch is required, we will update this announcement. You do not need to deinstall EM 12c or move the repository to an 188.8.131.52 database.
Sure hope Oracle quickly finishes testing and can restore support for DB 12c as the OEM repository. In the meantime, everyone should know about this note number and be aware when making architecture changes related to their OEM 12c environment.

In Database Archiving In Database Archiving is a new feature of Oracle 12c meant to solve management of historical data inside the database. Like its name says, this functionnality leaves data into the database, so it remains accessible if you need it. With In Database Archiving, historical data remains in the database but is invisible to [...]

This week I’ve been enjoying spending some time at Oracle Open World in San Francisco, CA. While here, I’ve been talking with everyone, friends old and new, and it came to my attention that it would be a good idea to have some useful templates for Oracle GoldenGate parameter files. With this in mind, I decided to create some generic templates with comments for Oracle GoldenGate processes. These templates can be found on my Scripts page under “Oracle GoldenGate Parameter Templates”. These files are in a small zip file that can be downloaded, unzipped and used in creating a basic uni-directional configuration.
By using these templates, you should be able to do:
- Review useful examples for each Oracle GoldenGate process (Manager, Extract, Pump, Replicat)
- With minor changes, quickly get uni-directional replication going
- Gain a base understanding of what how simple Oracle GoldenGate parameter files work

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.

The 2009 Mazda 6 is a entrance-wheel-pressure midsize sedan. There are seven trim ranges: i SV, i activity, i journeying, i Grand visiting, s recreation, s journeying and s Grand visiting. fashions with the i prefix include the 4-cylinder engine, whereas fashions with the s prefix come with the V6.
the worth leader i SV comes usual with sixteen-inch metal wheels, a manually top-adjustable driver seat, full power accessories, a six-speaker CD stereo machine with guidance-wheel-installed audio controls, air-conditioning and a tilt/telescoping steerage column. The i recreation adds cruise keep an eye on, an auxiliary enter jack and keyless entry. The i traveling edition steps up the function content material with 17-inch alloy wheels, foglights, a commute pc, a power driver seat, keyless ignition/entry, electroluminescent gauges, black patterned accent pieces and a leather-based-wrapped steerage wheel and shift knob. The i Grand travelling model provides xenon headlights, heated leather seats with a reminiscence perform for the driving force seat, Bluetooth connectivity, twin-zone automatic climate regulate, auto-dimming mirrors and an auditory blind-spot monitoring device.
The s fashions feature the corresponding i models' usual gear together with just a few enhancements -- the s sport comes with 17-inch alloy wheels and dual exhaust retailers, and the s traveling and s Grand travelling add 18-inch alloy wheels.
A comfort package for visiting models tacks on most of the Grand visiting's standard luxuries, while the Moonroof and Bose bundle adds a sunroof and an upgraded audio system to journeying and Grand journeying fashions. A navigation system is to be had most effective on the Grand journeying. other choices include faraway start, an in-sprint six-CD changer and satellite tv for pc radio.

The front-wheel-pressure 2009 Mazda 6 is powered through either a 2.5-liter 4-cylinder engine or a three.7-liter V6. The 4 generates 170 horsepower and 167 pound-feet of torque, while the V6 pumps out 272 hp and 269 lb-ft. A six-velocity manual transmission is standard on 4-cylinder fashions, with a five-velocity automated non-compulsory on all however the i SV. A six-velocity computerized is necessary on V6-powered models.
gasoline-economy estimates stand at 20 mpg metropolis/29 freeway and 23 mixed for 4-cylinder fashions with the manual transmission, while the five-speed auto improves the 4's numbers to 21 mpg metropolis/30 freeway and 24 blended. These are classification-competitive numbers. however, if you go for the V6, estimates drop to 17 mpg city/25 freeway and 20 mixed, which is ready as bad because it gets on this phase.
common problems with mazda 6
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.
Today’s blog post is the first in a three-part series with excerpts from our latest white paper, Microsoft Hadoop: Taming the Big Challenge of Big Data.
As companies increasingly rely on big data to steer decisions, they also find themselves looking for ways to simplify its storage, management, and analysis. The need to quickly access large amounts of data and use them competitively poses a technological challenge to organizations of all sizes.
Every minute, about two terabytes of data are being generated globally. That’s twice the amount from three years ago and half the amount predicted for three years from now.
Volume aside, the sources of data and the shape they take vary broadly. From government records, business transactions and social media, to scientific research and weather tracking, today’s data come in text, graphics, audio, video, and maps.

A book tittle "I Heart Logs - Event Data, Stream Processing, and Data Integration" by Jay Kreps. It's very interesting. I'd like to know what I can learn from it, how logs work in distributed systems and learn from author who works at LinkedIn. A book! Not much for the number of pages. However, it gives much more for data flow idea, how logs work and author still shows readers why logs are worthy of reader's attention. In a book, that has only 4 chapters, but readers will get concept and idea about Data integration (Making all of an organization’s data easily available in all its storage and processing systems), Real-time data processing (Computing derived data streams) and Distributed system design (How practical systems can by simplified with a log-centric design). In addition, I like it. because author wrote from his experience at LinkedIn.
After reviewing: A book refers a lot of information(It's easy on ebook to click links) that's useful. Readers can use them and find out more on the Internet and use. For Data integration, It's focused to Kafka software that is a distributed, partitioned, replicated commit log service. It provides the functionality of a messaging system. Additional, It gave why the Big Data Lambda Architecture is good for batch system and a stream processing system and point about things a log can do.
So, Readers will be able to learn:
- Learn how logs are used for programmatic access in databases and distributed systems
- Discover solutions to the huge data integration problem when more data of more varieties meet more systems
- Understand why logs are at the heart of real-time stream processing
- Learn the role of a log in the internals of online data systems
- Explore how Jay Kreps applies these ideas to his own work on data infrastructure systems at LinkedIn

I was testing SQL plan baselines on a base 184.108.40.206 release of Oracle on a 64 bit Linux virtual machine. I ran DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE to create a SQL plan baseline for a test query after running that query once to get its plan in the cursor cache. When I ran the test query after creating the SQL plan baseline and called dbms_xplan.display_cursor to see its new plan I got an ORA-01403 error:
ORCL:SYSTEM>select * from table(dbms_xplan.display_cursor(null,null,'ALL')); PLAN_TABLE_OUTPUT ------------------------------------------------------------------------------------ SQL_ID 4mu5a860ardpz, child number 1 An uncaught error happened in prepare_sql_statement : ORA-01403: no data found NOTE: cannot fetch plan for SQL_ID: 4mu5a860ardpz, CHILD_NUMBER: 1 Please verify value of SQL_ID and CHILD_NUMBER; It could also be that the plan is no longer in cursor cache (check v$sql_plan)
I applied patch 19183482 to my test system and the ORA-01403 error went away:
ORCL:SYSTEM>select * from table(dbms_xplan.display_cursor(null,null,'ALL')); PLAN_TABLE_OUTPUT ------------------------------------------------------------------------------------- SQL_ID 4mu5a860ardpz, child number 1 ------------------------------------- select sum(blocks) from test Plan hash value: 1950795681 --------------------------------------------------------------------------- | Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time | --------------------------------------------------------------------------- | 0 | SELECT STATEMENT | | | | 29 (100)| | | 1 | SORT AGGREGATE | | 1 | 3 | | | | 2 | TABLE ACCESS FULL| TEST | 2844 | 8532 | 29 (0)| 00:00:01 | --------------------------------------------------------------------------- Query Block Name / Object Alias (identified by operation id): ------------------------------------------------------------- 1 - SEL$1 2 - SEL$1 / TEST@SEL$1 Column Projection Information (identified by operation id): ----------------------------------------------------------- 1 - (#keys=0) SUM("BLOCKS") 2 - "BLOCKS"[NUMBER,22] Note ----- - SQL plan baseline SQL_PLAN_dscatqjvyk4qy6b581ab9 used for this statement
Here is a zip of the script that I ran to create the ORA-01403 error and the output that it generated with and without the patch applied on my test database: zip
Here is a list of the bugs that patch 19183482’s readme says it will fix:
14512308: SPM BASELINE PLAN CANNOT BE REPRODUCED
15858022: ‘LIBRARY CACHE: MUTEX X’ AND LIBRARY CACHE LOCKS PURGED_CURSOR
16400122: SPIKES IN LIBRARY CACHE
16625010: SPM BASELINE NOT WORKING FOR SQL CALLED FROM PL/SQL
I haven’t gotten very far into my investigation of SQL plan baselines but it looks like it would be a good idea to apply 19183482 before using SQL plan baselines on 220.127.116.11. I barely got started using SQL plan baselines and I immediately hit this bug.
