Parallel Purge Performance Optimization (Doc ID 2251699.1)

Last updated on MAY 15, 2023

Applies to:

Oracle SOA Suite - Version and later
Information in this document applies to any platform.


When running parallel purging in an SOA environment, you may notice that the performance is slower than expected. An AWR report may show the following statements taking excess time:

delete from AIA_SOAINFRA.composite_instance_assoc where assoc1_composite_instance_id in ( select id from AIA_SOAINFRA.composite_instance_purge) or assoc2_composite_instance_id in ( select id from AIA_SOAINFRA.composite_instance_purge)

There is a patch available to improve the performance of these scripts.
