Know New Marketing - What in the H are you talking about?

Ken Pulverman - Fri, 2007-09-21 12:52
.....yes it's a play on words....I'm fond of those, and if we ever meet in person, or perhaps even in this blog, you'll have to endure some bad puns as well.

So what am I getting at? Well a growing number of us believe that marketing, as we currently know it, is dead. As consumers we are tired of the window dressing, snake oil, and spin. Tell us what is is, what is does, and why I should care. ...and make it quick, because I have an inbox full of spam like you wouldn't believe, or maybe you would.

Why did it die? Simple. Trust. What was that our scholar of a president tried to reiterate - Fool me once, shame on you. Fool me twice...and that is where he lost it, but you know what comes next.

Collectively we are sick of the junk mail, the valueless untargeted commercials, the mailbox full of crap. In our limited time on this rock, we search for meaning and purpose and there are a whole bunch of direct marketers who want to waste that precious time. We trusted you, and you burned us one too many times. Like many folks, I've moved to triage mode on the tons of messages trying to reach me. If I can figure out what it is with reasonable certainty it gets deleted or thrown out without ever being opened. I am currently looking for a shredder big enough to accept those 20 page credit card offers poorly masquerading as important courier envelopes, unopened of course.

So as you can imagine, it produces a fair bit of cognitive dissonance for me to work as a marketer. Fortunately there are a growing number of us hell bent on leveraging new marketing techniques to prove the substantial ROI of marketing.

With the democratization of all of the media channels, marketing today is about conversations. Broadcasts and monologues are so yesteryear. This blog will explore how to reach your customers, members, constituents post Marketing 1.0 through the conversations that matter to them (and guess what, its almost never going to happen on your website).

So buckle up, java down and join me in this dialogue where we will chart the course for where we go from here. The good news is that the only way is up.

The big news for Canada

Peter Khos - Fri, 2007-09-21 11:33
Most of the news last week in Canada has been on the fact that the Canadian dollar is almost at par with the US dollar. The last time that it was at par was in 1976 (more than 30 years ago). What is so special about it? Well, depending on which perspective you are coming from, there are ramifications. For example, as a consumer there are savings to be had depending on what products are being Peter Khttp://www.blogger.com/profile/14068944101291927006noreply@blogger.com2

OC4J ping timeout issues

Vidya Bala - Thu, 2007-09-20 16:43
We recently went with a Jdev Application using Oacle Application Server 10.1.3. While the deployment went fine, a few days after the deployment we started noticing oc4j ping timeout issues in the opmn.log. After the OC4J ping timeout OC4J tries to restart itself. We checked the max heap size - the max heap size looks good. There is not much activity on the server so we feel the default ping timeout of 20 seconds should be sufficient. I don't believe it can be a JDK version issue either - since out dev/test environment does not have this issue and is on the same version. will be great to know if anybody has run into a similar issue and know of any possible solutions.

Oracle 11g New Features DBMS_ADDM for RAC

Virag Sharma - Thu, 2007-09-20 08:37
Virag Sharma virag123@gmail.com

In OCP Oracle Database 10g Exam Guidechapter 3 “Automatic Database Management” there is question


5. To retrieve the ADDM reports using SQL, what do you need to do?

A. Run the addmrpt.sql SQL script
B. Use the DBA_ADDM view
C. Use the DBA_ADVISOR view
D. Use the DBMS_ADDM package

Answer “A” is correct and D is wrong because there is no PL/SQL package named DBMS_ADDM.
But in 11g , it is not true , i.e. Package DBMS_ADDM is there in 11g. In case of RAC script
addmrpt.sql
run give report for single instance, not report of all instance in RAC. But using DBMS_ADDM , we can generate report for all instance of RAC.

Different mode of DBMS_ADDM

  1. Database Mode Instance Mode
  2. Partial Mode

Database Mode of DBMS_ADDM


In database mode DBMS_ADDM , analyze all instance in RAC

VAR tname VARCHAR2(30);
VAR start_snap_id number;
VAR end_snap_id number;

BEGIN

:tname := 'DB_MODE_TEST_RAG';
:start_snap_id := 100 ;
:end_snap_id := 200 ;
DBMS_ADDM.ANALYZE_DB(:tname, :start_snap_id, :end_snap_id);

END;

Instance Mode of DBMS_ADDM
In Instance mode DBMS_ADDM , analyze one particular instance

VAR tname VARCHAR2(30);
VAR start_snap_id number;
VAR end_snap_id number;
VAR INST_NUM number;
BEGIN
:tname := 'INST_MODE_TEST_RAG';
:start_snap_id := 100 ;
:end_snap_id := 200 ;
:INST_NUM := 2;
DBMS_ADDM.ANALYZE_INST(:tname,:start_snap_id,:end_snap_id, :INST_NUM );
END;

/

Partial mode of DBMS_ADDM

In partial mode DBMS_ADDM analyze subset of instances. for example we want to analyze instance 2 and 4 out of four node RAC

VAR tname VARCHAR2(30);
VAR start_snap_id number;
VAR end_snap_id number;

BEGIN

:tname := 'PART_MODE_TEST_RAG';
:start_snap_id :=100;
:end_snap_id := 200;
DBMS_ADDM.ANALYZE_PARTIAL(:tname,'2,4', :start_snap_id, :end_snap_id);

END;

/

Displaying an ADDM Report
  SET LONG 1000000 PAGESIZE 0;
   SELECT DBMS_ADDM.GET_REPORT(:tname) FROM DUAL;

or

SELECT DBMS_ADDM.GET_REPORT('DB_MODE_TEST_RAG') FROM DUAL;

INI Madness Tamed!

Mark Vakoc - Wed, 2007-09-19 22:52
As many might be aware the task of managing the INI files, used to store the configuration of our server based products, can be difficult at best. Server Manager addresses many of these problems in the following ways:

Complete INIs:
Server Manager provides a web based tools release specific mechanism for editing the configuration files of our server based products. Using Server Manager there should be no reason to manually edit the INI files directly. Server Manager provides a web based view/editing of all the configuration files.

Server Manager utilizes metadata about configuration settings that are delivered with each tools release. To accomplish this we performed many searches over the entire codebase to find every configuration item used. Our policy is: if something is configurable via INI it is configurable via Server Manager. This search resulted in the addition of many, some possibly obscure, configuration settings. It also resulted in the removal of many configuration items that have historically been delivered but are no longer relevant.

For existing enterprise servers that are registered with SM many configuration settings that were present in the JDE.INI that are no longer used will remain in the file, if present, but won't appear using the Server Manager GUI. For our web based servers the INIs are created when the instance is created, so will perfectly match the tools release initially used. If a setting is present in these web based INIs and the server is later upgraded to a release that obsoletes a setting that parameter will still remain in the file, but will no longer be viewable through the management console.

It is, of course, possible that we missed a setting. We did our best, but there are a lot of settings to manage. If a setting was missed and is therefore not available through the management console application it may always be edited directly within the file. All settings not known to SM will be maintained during tools release upgrades/downgrades.

Documentation:
Each configuration item is identified using a short, human readable description. An extended description is provided via the online help and bundled documentation. Default values, where applicable, are provided as reference. Many parameters provide a list of values detailing exactly what is allowed for each setting. For reference the documentation provides the INI filename, section, and entry for each setting.

We've also provided a reference document with the product detailing each setting. As of this writing this is over 350 pages. All the information in the documentation is also available in online help. If you are looking for a particular setting and are having trouble locating it using the new descriptions the documentation allows a quick lookup based on the INI entry details.

This reference documentation is current as of the 8.97 tools release. It will be kept current for all future tools releases. The reference may also be of assistance to earlier tools release but be aware that not all settings will be applicable to the earlier releases.

Relevant INIs:
Another task we undertook was to remove the configuration parameters that are not relevant to the product. Historically the JAS.INI and JDBJ.INI used for web servers were simply duplicated for the other web based products (collaborative portal, transaction server, PIMSync server, and the new business services server). We evaluated these products and removed from their configuration parameters that didn't apply. This means that each server has it's own unique set of configuration parameters. We hope this will reduce confusion in not appearing to require configuring parameters that do not apply to the server.

The transaction server (RTE) also previously contained three separate copies of each configuration file, one for each of the EARs that make up the product. This has been removed and only a single set of configuration files are shared among all the EARs.


There's much more to talk about configuration management in Server Manager: server groups, configuration comparison, and audit history. I hope to post on those topics in the future.

Quick History of Me

Mark Vakoc - Wed, 2007-09-19 22:24
Here's a quick background of who I am, why I'm blogging, and what I hope to accomplish here.

I have been with JD Edwards/PeopleSoft/Oracle for almost ten years now. The first three or so years were spent on the support organizations SWAT team flying to customer sites to address specific customer issues and provide technical assistance. Life on the road was great; I traveled to more than twelve countries and countless client sites and really enjoyed the work. It came time to stop traveling so much so I settled down in the Denver area and created the Support Assistant diagnostic product. I'm still very proud of SA, and am glad to say that the product is alive and kicking. More on that later.

After working primarily on SA for five or so years I decided to tip my hat into something new. I wanted to apply my experience from the field and support organizations and create something new. The result is Server Manager. Specifically, I wanted to address
  • The difficulty in installing and upgrading our server based products
  • The difficulties around configuration management; understanding all the configuration parameters and managing the configuration of servers across an E1 installation
  • The difficulty in monitoring the activity of E1 servers
  • The difficulty associated with troubleshooting servers when something goes wrong
Hopefully you'll see that Server Manager addresses these and many other administration activities that will truly result in a lower cost of ownership.

As someone unbelievably addicted to blogs, generally of a geeky nature, I've been "inspired" by many others to use this forum to publish tips, tricks, knowledge, and general musings on the product of which I'm so proud. I'm particularly inspired by a blog by a co-worker entitled 'The Buttso Blathers' with very insightful posts on all things OAS (Oracle Application Server).

There is one thing this blog does not represent; it is not a support forum or a place to seek help.  So tune in and learn more about the exciting Server Manager product.

Thanks!

Mark Vakoc - Wed, 2007-09-19 22:19
Before digging into the product itself I want to express some thanks to the team that worked on Server Manager. At this point I'll let the involved parties remain anonymous. This was a team effort, and I want to express my personal thanks to the development team and quality assurance team that helped create the product.

So, for all those involved in Server Manager, I say thanks.

Making Sense of Fusion Middleware

I was in Redwood last week and got a chance to meet some of the best minds in Server Technologies including a few ex-colleagues and a couple of guys on the revered

During the Cold War, US and Russian analysts spent millions of hours analyzing one another’s public pronouncements trying to understand what was really going on with the other side.In the same manner today, we often find ourselves trying to understand what Oracle is trying to communicate (or not communicate) through their many announcements, white papers and presentations.

Payroll Reversal

RameshKumar Shanmugam - Sun, 2007-09-16 16:38
After running the payroll and if post run processing has already occured we cannot correct the payroll by Retry, even in case of roll back we need to roll back the complete Payroll for correcting an entry for one or two assignment.
In these cases we can use Payroll Reversal. In short Payroll Reversal helps to correct the run result for an single assignment

To Reverse the Payroll run for an assignemnt
(R) US HRMS Manager
(N) Fast Path > Reverse Payroll Run
Select the Assignment that you need to reverse from the LOV, Tick the Reverse Check Box for the Payroll that we need to reverse and save the work. Consolidation set for the run will be automatically displayed for the Reversal
Now the Run Result is been reversed to the Value before the payroll Run. Now you can modify the Entry and start processing your payroll again.

Try this out!!!

Query to determine the clustering factor before you create the index

Mihajlo Tekic - Sun, 2007-09-16 10:33
I found the following query useful to determine the clustering factor for the indexes that has not been created yet.

select count(1) clustering_factor
from
(
select dbms_rowid.rowid_block_number(rowid) block_no,
list of the indexed columns,
count(1) num_rows,
LAG(dbms_rowid.rowid_block_number(rowid))
over (order by list of the indexed columns) prev_block
from table_name
group by dbms_rowid.rowid_block_number(rowid),
list of the indexed columns
order by list of the indexed columns
)
where block_no<>prev_block or prev_block is null


Let's take a look at the following example:

SQL> create table test
2 tablespace example
3 as select
4 mod(rownum,8) col1
5 lpad('x',1000) col2
6 from all_objects
7 where rownum<=1000;


Using the following query, we can see that there are about 7 rows per block (block size 8192) that makes the records with same COL1 to be scattered across different blocks:

SQL> select num_rows_in_block, count(1) blocks
2 from
3 (
4 select block_no, count(1) num_rows_in_block
5 from
6 (
7 select dbms_rowid.rowid_block_number(rowid) block_no
8 from test
9 )
10 group by block_no
11 )
12* group by num_rows_in_block
SQL> /

NUM_ROWS_IN_BLOCK BLOCKS
----------------- ----------
6 1
7 142

Let see how big would be the clustering factor of an index built on TEST(COL1).

SQL> select count(1) clustering_factor
2 from
3 (
4 select dbms_rowid.rowid_block_number(rowid) block_no,
5 col1,
6 count(1) num_rows,
7 LAG(dbms_rowid.rowid_block_number(rowid))
8 over (order by col1) prev_block
9 from test
10 group by dbms_rowid.rowid_block_number(rowid), col1
11 order by col1
12 )
13* where block_no<>prev_block or prev_block is null
SQL> /

CLUSTERING_FACTOR
-----------------
1000

The result was pretty obvious.
Now let's add another column COL3 in the table TEST and set its value to mod(col1, 4).
This will make the blocks to contain at most two records with the same value of COL3.

SQL> alter table test
2 add col3 number;

Table altered.

SQL> update test set col3=mod(col1,4);

1000 rows updated.

SQL> commit;

Commit complete.

SQL>

Now let see what would be the value of the clustering factor of the index created on COL3 column:

SQL> select count(1) clustering_factor
2 from
3 (
4 select dbms_rowid.rowid_block_number(rowid) block_no,
5 col3,
6 count(1) num_rows,
7 LAG(dbms_rowid.rowid_block_number(rowid))
8 over (order by col3) prev_block
9 from test
10 group by dbms_rowid.rowid_block_number(rowid), col3
11 order by col3
12 )
13* where block_no<>prev_block or prev_block is null
SQL> /

CLUSTERING_FACTOR
-----------------
572

Now let's create the actual indexes and see what their clustering factor would be:

SQL> create index test_col1_idx on test(col1);

Index created.

SQL> create index test_col3_idx on test(col3);

Index created.

SQL> select index_name, clustering_factor
2 from user_indexes
3* where table_name='TEST'
SQL> /

INDEX_NAME CLUSTERING_FACTOR
------------------------------ -----------------
TEST_COL1_IDX 1000
TEST_COL3_IDX 572

Perfect insights about the importance of the clustering factor for calculating the cost I found in Jonathan Lewis's book Cost-Based Oracle Fundamentals.

Let's go back to the very first query in this post. Why I think this query is useful?
Because sometime, even though I think some columns are perfect combination to create index on, the index might not be used by the optimizer because the clustering factor is big.
It can give you an initial clue how effective some index could be.

Oracle 11g Documentation

Renaps' Blog - Fri, 2007-09-14 09:02

Since reading the documentation is always a good idea when a new Oracle release is out, I decided to read Oracle® Database Upgrade Guide and the Oracle® Database New Features Guide before getting into the 11g installation guide.

It is funny how I haven’t yet downloaded the new Oracle 11g database and I am already using one of its new features!

Oracle 11g now enables users to send out comments, making it faster and easier to everyone to enhance the documentation.
This new feature have also been discussed here:

While reading through the 2 guides, I used this new feature to report a couple of errors:
Oracle has responded to my user comments pretty fast:

Oracle 11g Database New Features: Data Guard Enhancements

Virag Sharma - Wed, 2007-09-12 07:59

Why We need Data Guard ?? for

  • Data protection
  • Data Availability

11g Increase ROI from standby systems and enhance manageability, New feature like Active Data Guard , Snapshot standby make better ROI.

Here is some data guard category and there enhancement

1) Data Protection
  • Advanced Compression
  • Lost-write protection
  • Fast-Start Failover
2) Increase ROI
  • Active Data Guard
  • Snapshot Standby
3) High Availability
  • Faster Redo Apply
  • Faster failover & switchover
  • Automatic Failover using ASYNC
4) Manageability
  • Mixed Windows/Linux

Active Data Guard

Oracle Active Data Guard 11g – a new Database Option
Enables read-only access to a physical standby database while Redo Apply is active
It is now possible to query a physical standby database while Redo Apply is active.This new capability increases your return on investment in Data Guard technology because a physical standby database can now be used to offload queries from the primary database in addition to providing data protection.
( We can do same with logical standby , what is diffrent here , well redo apply method is faster in physical stand by ie redo apply methode is diffrent in physical standby)


  • Stop log apply
Alter database recover managed standby database cancel;
  • Open database for read-only access
alter database open
  • Once database open start redo apply
alter database recover managed standby database
using current logfile disconnect from session;


Snapshot Standby


This enhancement is good example of ROI. This feature allow us to better utilization of standby. This feature Truly leverages DR hardware for multiple purposes.For example convert physical database to snapshot standby database do testing/ application patching etc. After testing convert back snapshot database back to physical standby.













  • -- Convert physical database to snapshot
ALTER DATABASE CONVERT TO SNAPSHOT STANDBY;
  • --
  • -- Do testing on database
  • --
  • -- Convert snapshot Database to physical database

ALTER DATABASE CONVERT TO PHYSICAL STANDBY;


This Similar to storage snapshot , but it useage same space , not additional space is needed ( I know this possibly can achieve in 10g R2 too , using flashback feature , But for sure it is not easy as it is in 11g )


Redo compression

To transport redo data in compressed form to destination use COMPRESSION attribute.
By default compression is disabled.


  • Alter system set log_archive_dest_1 = 'SERVICE=standby1 compression=ENABLE';

  • select dest_name , compression from v$archive_dest;

    SQL>
    DEST_NAME COMPRES
    --------------------------------- -------
    LOG_ARCHIVE_DEST_1 DISABLE
    LOG_ARCHIVE_DEST_2 ENABLE
    LOG_ARCHIVE_DEST_3 DISABLE
    LOG_ARCHIVE_DEST_4 DISABLE
    LOG_ARCHIVE_DEST_5 DISABLE
    LOG_ARCHIVE_DEST_6 DISABLE
    LOG_ARCHIVE_DEST_7 DISABLE
    LOG_ARCHIVE_DEST_8 DISABLE
    LOG_ARCHIVE_DEST_9 DISABLE
    LOG_ARCHIVE_DEST_10 DISABLE

    10 rows selected.

Data Protection

New Initialization parameter db_lost_write_protect Introduced. This parameter Compare versions of blocks on the standby with that in the incoming redo stream
Version discrepancy implies lost write on either primary or standby database

db_lost_write_protect


Managibilty Enhancement

SYS user and password files no longer required for redo transmission authentication. Non-SYS user can be specified through the parameter, This user must have the SYSOPER privileges, Requires password for this user to be the same at primary and all standbys
Upon SYSDBA / SYSOPER changes, password file must be copied from the primary to all physical standby databases

redo_transport_user

Data Guard Support for Heterogeneous Primary and Standby Systems in Same Data Guard Configuration (- Since 11g Linux installer only available, so not able to test this feature)

Fast-Start Failover

Immediate automatic failover for user-configurable health conditions



DGMGRL> show FAST_START FAILOVER
DGMGRL> ENABLE FAST_START FAILOVER [CONDITION ];

Condition examples:
  • Datafile Offline
  • Corrupted Controlfile
  • Corrupted Dictionary
  • Inaccessible Logfile
  • Stuck Archiver
  • Any explicit ORA-xyz error


Application can also request for failover using package DBMS_DG

DBMS_DG.INITIATE_FS_FAILOVER

My new laptop

Siva Doe - Mon, 2007-09-10 15:15

Last week our team got couple of new laptops. Sony Vaio VGN-FZ17G.
Looks shiny and sleek. It came loaded. Core2 Duo @ 2.00 GHz, 2GB RAM,
160G Disk, Vista Home Premium. The battery life sucks though. With the
default power plan of Vaio Optimized, just about 40 mins of battery
backup. May be it will give more with power saver plans.

Coming to the main story - with the help of GParted, resized the Vista
partition. Then started installing Nevavda build 72. I was all worked
up eager to see Caiman installer at work. Alas, no such luck. Looks
like the Nvidia GeForce 8400M GT card was not supported by the bundled
driver in nv_72. So, I had to endure one more session of the familiar
blue/green console installer.

First thing I did was to create a ZFS pool and had /opt in ZFS (is
this safe?). Next, downloaded and installed Nvidia latest driver,
which worked beautifully. Now Xorg is running at the native 1280x800
resolution. Strangely, my Wifi is working but not my ethernet port.

These will be my next steps. Get the ethernet working (Marvell Yukon).
Install Compiz Fusion (thanks Erwann), Second Life for Solaris (thanks
Dana). Install Sun Studio 12 (I have to get back to work, dont I?);
Coolstack. The others will be TBD later. Sound is not working, but
this will be my lowest priority though.

Latest supercomputer!

Peter Khos - Sun, 2007-09-09 01:38
I found this news very interesting indeed. The latest supercomputer is here and it is not controlled by government or private agencies. Instead, it is under the control of (most likely) criminals and the question being asked is "what do they planned to do with it?"It's scary but just imagine the possibilities and none of them are good at all. I think it might be prudent for the white hats to Peter Khttp://www.blogger.com/profile/14068944101291927006noreply@blogger.com0
