CRS-0245: User doesn't have enough privilege to perform the operation


Reason of CRS-0245 is that you are executing “srvctl” command to perform a task that is not authorized for current logged in user. For example, I was trying to remove a RAC database from CRS using srvctl and I faced this error because I was executing this command as “grid” user whereas I was supposed to execute this command as “oracle” user that is RDBMS software owner.

PRKO-3141 : Database could not be removed because it was running


If we use “srvctl” command to remove a database from CRS (in case of RAC) or Oracle Restart (in case of single server GI installation), we might face this error if database is currently  running. To successfully remove a database from CRS using srvctl, either shutdown the database (all instances), or alternatively you can use “–f” (for versions bellow 12c) or “-force” (for 12 and above) option.

Similar steps may also be followed if targets other than database targets face same issue.
