12.2.4 - Pycorefx.sql - Performance Issue with hrglobal
Last updated on JANUARY 13, 2017
Applies to:Oracle Human Resources - Version 12.2.4 and later
Information in this document applies to any platform.
On upgrade to Oracle EBS Applications 12.2.4, hrglobal performance is poor.
Steps to Reproduce:
After completing 12.2.4 upgrade (12.1.3 > 12.2.0 > 12.2.4), customer ran datainstall utility to select Global legislation and then applied $PER_TOP/patch/115/hrglobal.drv using adop.
Applying hrglobal driver took around 5 hours in our environment. pycorefx.sql ran for 4.5 hours. Here is the sql that was running for hours:
where user_name = t_dbi_del(i).user_name
and user_entity_id = t_dbi_del(i).user_entity_id;
Here is the row count in ff_database_items and ff_databas_items_tl tables in before and after applying hrglobal driver:
ff_database_items_tl - 26326285
ff_database_items - 1548618
ff_database_items_tl - 11660980
ff_database_items - 685953
WHAT IS WORKING
Customer did not experience this issue in earlier upgrades (12.1.3->12.2.0->12.2.3->12.2.4). This is the 1st time we upgraded to 12.2.4 directly from 12.2.0.
All their earlier 12.2.4 upgrades were done from 12.2.3.
