Applies to:Business Intelligence Server Enterprise Edition - Version 184.108.40.206.4 and later
IBM AIX on POWER Systems (64-bit)
- Oracle Business Intelligence Enterprise Edition (OBIEE) 220.127.116.11.0 BP4 on IBM AIX on POWER Systems (64-bit).
- There are Stuck Threads for OBIEE. In Administration-Manage Sessions-View Log you can find running queries that have been running for over 5 minutes, and a lot of Queued queries also running for over 5 minutes, sometimes there's a lot of them, and the quereis are saying Starting.
- In the 'View Log' option in OBIEE you wanted to see if there were any stuck running queries, and there was a large amount of running queries running for over 10 minutes.
- Once the stuck threads started going up, you notice the CPU usage is high and then received a warning from the WebLogic Server Console.
- At this point, it is normally when you get a core dump, from nqserver (BI Service) or sawserver (Presentation Server) and finally users are not able to log in OBIEE.
Several error messages like this:
