Symptoms

While using Oracle E-Business Suite 12.2, Self-Service Web Page performance is very poor.  It is taking longer than expected to navigate from one page to the next, ~15 seconds or more in most cases.

Steps to reproduce the issue:

1. Login to Oracle E-Business Suite and navigate through Self Service Pages.  Notice the following:

• The login page taking too much time to load.
• The OAF_HTML pages taking a long time to open.
• The overall navigation time between the pages is very long.

A review of an AWR report during the time of the performance issue shows the following WF related SQLs as Top SQLs:

The SQL Ordered by CPU Time shows this:

Changes

 This usually happens after the upgrade from EBS 12.1+ to EBS 12.2+ but could occur at any time if Workflow Notifications become too numerous.
