Partitioning and Purging Best Practices for Oracle E-Business Suite

For my last post prior to a Thanksgiving holiday, here's a treat for DBAs looking to squeeze some additional performance out of existing database hardware. 

Partitioning Example GL Balances Table:

Ahmed Alomari and Mohsin Sameen put together an excellent OpenWorld 2006 session on optimizing the performance of E-Business Suite environments via partitioning and purging.  Starting with a quick survey of how partitioning has changed from the Oracle 8 database release all the way up to Oracle 10g, Ahmed and Mohsin then dive into:
  • Overview of partitioning benefits and some Apps modules that take advantage of this out-of-the-box, and custom partitioning
  • Technical advantages, such as backup, index rebuild, and Cost Based Optimization (CBO ) implications
  • Integration with Information Lifecycle Management (ILM) for data storage on lower-cost storage devices
  • Techniques and relative merits of range, list, hash, and composite partitioning
  • In-depth discussion of index partitioning methods, including the new Global Hash Partitioned (prefixed) capabilities in 10g
  • Useful data dictionary views for partitioning
  • Before and after comparisons, and actual customer case studies with real statistics
  • Review of purging and archiving programs shipped out-of-the-box with the E-Business Suite
  • Samples of typical customer purging runs
  • Review of the latest Purge Portal released with the E-Business Suite 11.5.10
  • Sneak previews of Release 12 enhancements to the Purge Portal, like this (I can't resist a screenshot):

Very usefull. I currently looking at develoing a archiving and purging plan for the Oracle E-business suite.

Hi Steven.
We have a doubt.

Every mounth we execute rebuild and move in many tables in our environment (12.0.6 RDBMS 10.2.0.4). The impact is long time to execute these tasks.

My quaetion is:
Is it really necessary to do this?

I read some doc:
Index Rebuild, the Need vs the Implications [ID 989093.1]
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:2913600659112
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:35336203098853
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:913264544589

And now I think that is not necessary to do this.

Thank you

Tiago Doné

Tiago,

One of our EBS database architects replied with:

"As a general rule, I would agree with AskTom. That doesn't mean there aren't exceptions, and it comes down to the small number of transaction tables. And why are they doing it? Purging data is one thing, but index rebuilds on their own doesn't seem particularly cost effective."

Regards,
Steven

Hi, Nilesh,

You've come across an article that was published in 2006. Unfortunately, the OpenWorld 2006 archives have been taken offline and are no longer available.

As of today, our latest database partitioning recommendations can be found here:

Hi Steven,

Sorry for replying to an old thread, but I am struggling to find the information anywhere, and I couldn't see it mentioned in the paper in the link provided.

Basically, I just wanted to know whether a separate partitioning license is required if we are using modules that have partitioned tables, but we haven't partitioned any tables ourselves? Or whether a restricted use license is granted in this case?

Regards
Neil

Hi, Neil,

If you use only the seeded partitions supplied with the E-Business Suite, no extra Partitioning Option licence is required. If you create your own partitions or modify the seeded ones, that will require a separate licence.

Regards,
Steven
