Analytics JMS queue Errors and Event Router Stops

(Doc ID 2217280.1)

Last updated on JANUARY 12, 2018

Applies to:

Oracle Knowledge - Version 8.5.1.5 and later
Information in this document applies to any platform.

Symptoms

When the Analytics Event Router stops moving data for a long period of time the JMS queue can stop functioning correctly.  Then Oracle Knowledge instances will receive errors and the Analytics event router server can crash when the queue fills up and then the ICs go down getting an Analytics error with a jms queue full message.  The Analytics events are collected in the .dat files need to be backed up and then processed when the system can be brought back up.  In order to restart the Analtyics event router server more memory is needed than when starting it with a mostly empty queue.  We recommend that the Analtyics Event router run with 2G - 3G of memory to account for any Event router outages or issues.

Changes

If the server stops running then these events are lost.  Some events can be recovered with the help of Oracle support.
