Performance Problems with Notifications When the Mailer has more Notifications to Process (Doc ID 1392647.1)

Last updated on SEPTEMBER 15, 2017

Applies to:

Oracle Workflow - Version 11.5.10.2 to 12.2.7 [Release 11.5.10 to 12.2]
Information in this document applies to any platform.

Symptoms


Customer is running EBS 11.5.10 + ATG Rup 7

Notifications are processed very slow on Fridays when the notification volume increases. Notifications are dequeued from WF_NOTIFICATION_OUT queue 2 or 3 hours after they were created.

The following actions were already taken but didn't help to improve performance:
1. wfntfqup.sql was already ran to re-created WF_NOTIFICATION_OUT manually
2. outbound thread was changed to 2
3. a new mailer was created
4. performed a coalesce on AQ IOTs and indexes for WF_NOTIFICATION_OUT queue
5. all the messages in PROCESSED status were purged

Changes

More time cards are generated on Fridays
