Hi,
These documents talk about purgin WF_NOTIFICATIONS_OUT queue. But document i mentioned
says.
7. Try rebuilding the WF_NOTIFICATION_OUT queue if necessary
The wfntfqup.sql script rebuilds the WF_NOTIFICATION_OUT queue by dropping and recreating
that queue, removing pending notification messages from the WF_DEFERRED queue, and
repopulating the WF_NOTIFICATION_OUT queue from the Oracle Workflow Notification System
tables.
Wfntfqup.sql Version >=115.9
If you have implemented Oracle Alert and the WFNOTIFICATION_OUT queue contains any pending_
alert e-mail messages, those messages must be processed before the queue can be rebuilt. The
wfntfqup.sql script checks the queue for any alert e-mail messages and, if it finds any, the
script returns an error message that specifies how many alert e-mail messages are pending
and indicates that these messages must be processed before the script can run.
Kindly suggest.
