ORA-00240 control file enqueue held for more than XXX seconds


ORA-00240 control file enqueue held for more than XXX seconds



Description： control file enqueue held for more than string seconds

Cause 1 :-

 The current process did not release the control file enqueue within the maximum allowed time.

Cause 2:-

 The issue was  investigated in unpublished Bug 7570453 - [3 RAC NODE]ORA-00240                       WHEN STARTUP AFTER UPGRADE TO 10.2.0.4.0 which was closed as Not a Bug.The                    Developers confirmed that this is just a warning to let the DBA know that a CF enqueue is                 being held for more than 120 seconds.

This is not an error, and error will occur if a CF enqueue is held for more than 900 seconds (15 minutes) and this is not the case here.

The message occurs when there are many datafiles in the database and  DBWriter  is taking too much time to release the CF enqueue due to having to open these  datafiles.

Action： 1. Reissue any commands that failed and contact Oracle Support Services with the incident information.

   2.  The recommendation will be to reduce this time by reducing the number of database files you have.It is more recommended having less but bigger datafiles  instead of smaller but lots of datafiles.

DBA_SCHEDULER_JOB_RUN_DETAILS and PURGE_LOG

How to purge DBA_SCHEDULER_JOB_RUN_DETAILS? Manually deleting from DBA_SCHEDULER_JOB_RUN_DETAILS is not recommended by oracle.DBA_SCHEDULER_JOB_RUN_DETAILS is a view that is using two master tables (scheduler$_job_run_details and scheduler$_event_log) and display the information about jobs history. As there is one procedure named PURGE_LOG and Oracle have Scheduler for this procedure. It will purges all rows in the job log that are older than 30 days.This is the default behavior of this procedure. You can change this to any number of days you want by setting the attribute "SET_SCHEDULER_ATTRIBUTE". e.g. exec DBMS_SCHEDULER.SET_SCHEDULER_ATTRIBUTE('log_history','15'); It will purge all logs older than 15days and it will maintain the history of 15days. But If you want manually purge these logs, you can use below solution:- exec DBMS_SCHEDULER.PURGE_LOG(log_history => 15, which_log => 'JOB_LOG'); It will purge all entries from the jog log that are o...

ORA-65016: FILE_NAME_CONVERT must be specified

ORA-65016: FILE_NAME_CONVERT must be specified I just started working on 12C version of oracle database.It's new to me and facing many problems. Error code: ORA-65016: FILE_NAME_CONVERT must be specified Description:"ORA-65016: FILE_NAME_CONVERT must be specified" normally occurs when you create a PDB.I will explain later what is a PDB. Cause and solution :  ORA-65016: FILE_NAME_CONVERT must be specified caused when Data files, and possibly other files, needed to be copied as a part of creating a pluggable database.Enable OMF or define PDB_FILE_NAME_CONVERT system parameter before issuing CREATE PLUGGABLE DATABASE statement, or specify FILE_NAME_CONVERT clause as a part of the statement and make sure the path you are giving to convert the file exists. I think if you are creating the PDB's using GUI then you will not face this error "ORA-65016: FILE_NAME_CONVERT must be specified". If you creating ODB using script and you have gave a wrong path then may you f...
