ORA-00240控製文件入隊持續超過XXX秒

ORA-00240控製文件入隊持續超過XXX秒


說明：控製文件排隊持有超過字符串秒

原因：1.當前進程沒有在最大允許時間內釋放控製文件入隊。
       2.未經發布的Bug 7570453 - [3 RAC NODE] ORA-00240在升級到10.2.0.4.0之後啟動的問題已被調查，該錯誤被關閉為Not Bug。開發人員確認這只是一個警告，讓DBA知道一個CF入隊被持有超過120秒。這不是一個錯誤，如果CF入隊超過900秒（15分鐘），則不會發生錯誤。
當數據庫中有很多數據文件時，會發生該消息。 DBWriter（dbw0）由於不得不打開這些數據文件而花費太多的時間來釋放CF入隊。

操作：1.重新發出失敗的任何命令，並與事件信息聯繫Oracle支持服務。

   2.建議通過減少數據庫文件的數量來減少這個時間。更多的是建議使用較少但較大的數據文件，而不是較小的數據文件。

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...
