Parallel Purge Performance Optimization (Doc ID 2251699.1)

Last updated on APRIL 11, 2017

Applies to:

Oracle SOA Suite - Version 11.1.1.7.0 and later
Information in this document applies to any platform.

Goal

When running parallel purging in an 11.1.1.7.x 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.
