BEA-337 [WebLogicServer] errors detected in EM12c

The ”Refresh From My Oracle Support” job in EM12c runs daily at 00:00 (midnight) by default.  If the OMS host is under load at that time (backups etc.) then this can cause the refresh job to run past the 10 minutes StuckThreadMaxTime limit, which leads to a stuck thread being detected within WebLogic, and EM raising the following incident:

Host=[host]
Target type=Oracle WebLogic Server
Target name=/EMGC_GCDomain/GCDomain/EMGC_OMS1
Categories=Diagnostics, Fault
Message=Incident (BEA-337 [WebLogicServer]) detected in /u01/app/oracle/middleware/oms12c/gc_inst/user_projects/domains/GCDomain/servers/EMGC_OMS1/adr/diag/ofm/GCDomain/EMGC_OMS1/alert/log.xmlat time/line number: Wed Feb 6 00:10:17 2013/1289
Severity=Critical

Looking at the log.xml file mentioned above, you’ll see something like this which clearly shows the stuck thread:

This can be resolved, by re-scheduling the ”Refresh From My Oracle Support” job to a less busier time.

Make sure you log into the Cloud Control Console as SYSMAN

Navigate to > Enterprise > Job > Activity > select ”Advanced Search” > select ”Refresh From My Oracle Support” for the ”Job Type” drop-down > “Go”

Then Edit the ”Refresh From My Oracle Support” job and update the Schedule.  I changed my Start Time from 12:00 AM to 12:00 PM whilst leaving the frequency etc. unchanged.
