Processing Item and PO Upload In Parallel Cause Deadlocks (Doc ID 2427451.1)

Last updated on JULY 25, 2018

Applies to:

Oracle Retail Merchandising System - Version 16.0.1 and later
Information in this document applies to any platform.

Symptoms



Actual Behavior
---------------

After you start processing a Purchase Order (PO) Upload, you see the deadlocks for an existing Item Upload which eventually causes the PO Upload to perform slow.

Expected Behavior
-----------------------
 Though Item and PO Upload belong to different AQ, these two AQs feed into one DB Scheduler. Hence, expect the application to provide a way where the user can define or feed in the scheduler to reduce the contention.


What is Working
-----------------------
There are no issues when only Item Induction.

Steps to Reproduce
-----------------------
The issue can be reproduced at will with the following steps:
1. Start Item Upload and PO Upload in parallel.
2. Notice the deadlocks.
