Workflow Background Process For OEOH Is Looping In The Workflow Deferred Queue (Doc ID 345090.1)

Symptoms

The Workflow Background Process (WFBG) is running for hours without completing.
The wf_item_activity_statuses_h table has over 80 million records, and is growing quickly.
The problem started after a new custom Workflow process was introduced to handle rate change orders.
It was observed that new items are being added at a very fast rate to the WF deferred queue.

Another symptom of this problem may be the archive log size growing rapidly when the WFBG process
is running.

STEPS
1. Submit the Workflow Background Process with the YNN or YYY options.

BUSINESS IMPACT
Since the Workflow uses a deferred booking mechanism, the orders are not being picked up and booked
by the WFBG as this process never completes normally. As such, orders cannot be picked and shipped.
Another impact is the large amount of data being built up in the Workflow tables, leading to large redo
logs in the database.

Changes

A custom Workflow process was introduced into Production recently.
