The Database 11.2.x APEX Session Ignores Created SQL Baseline which Affects Performance (Doc ID 1684250.1)

Last updated on FEBRUARY 14, 2016

Applies to:

Oracle Application Express (formerly HTML DB) - Version 3.2.1 and later
Information in this document applies to any platform.

Symptoms

Running SQL statements from APEX applications are slow, even though an SQL Baseline was created to speed them up. Tracing the APEX session showed that the database session which was opened by APEX was not taking into account the created SQL Baseline and the optimizer chose another (less effective) execution plan.

Changes

 Upgraded database from 11.1.0.7 to 11.2.0.3. It worked fine in 11.1.0.7
