Error: BEA-141281, unable to get file lock, will retry …

I have installed OBIEE 11g on OEL 5.7 and when I was trying to automate OBIEE 11g start up/shutdown scripts on Linux, I have faced “”error.

Description: This message indicates that WLS can not get file lock because other process still holds the lock. W LS will try again before timeout.
Cause: This is an information-level message only.
Action: If WLS fails to start due to unable to get file lock, then lock files need to be removed manually before restart WLS.

Go to  <installDirectory>/user_projects/domains/bifoundation_domain/servers/AdminServer/tmp, locate AdminServer.lok file and remove it.Then restart the WLS and all other BI services.
