Catalog is unable to attach/trigger PAM process.
In the USMHome/logs/view.log we see that Catalog is calling PAM SRF's:
DEBUG [Rule Action Executor-3] [ITPAMAction] Sending ITPAMCommand message to queue:itpam
However, PAM does not show any error and does try to run anything.
USM_HOME/logs/view.log also shows:
TRACE [WrapperSimpleAppMain] [ITPAMQueueManager] Blocked queues : [itpam]
PAM and Catalog restarts won't change the behavior.
SDM, Catalog: 17.4 RU5
EEM: 12.7.2.0
PAM: 4.4 CP04 HF01
ITPAM queue is in blocked state. This indicates that there is a constant failure happening between Catalog and PAM and after the retry count is exhausted, the ITPAM queue will go to blocked state to avoid unnecessary calls to PAM .
1. Log into Catalog as Administrator
2. Go to Home | Messages | Alerts | Click on "List Failed Alerts"
3. In the list an "ITPAM_QUEUE_FAILURE" alert should show up. Check the checkbox for this alert and click on "Retry failed action". This will unblock the ITPAM Queue and all the pending PAM processes which are waiting in queue will be triggered.
