搭建备库时报错“ORA-00203: using the wrong control files”
最近要做容灾了,我急急忙忙的想在测试环境先测试一边流程,结果还原备库的控制文件后,需要启动到mount阶段时报错:
SYS@lhrrac1DG> startup force mount ORACLE instance started. Total System Global Area 630501376 bytes Fixed Size 2230992 bytes Variable Size 440403248 bytes Database Buffers 180355072 bytes Redo Buffers 7512064 bytes ORA-00203: using the wrong control files ORA-00202: control file: '+DATADG/lhrrac1/controlfile/current.314.1014550361'
查看:
[root@raclhr-11gR2-N1 ~]# oerr ora 203 00203, 00000, "using the wrong control files" // *Cause: The mount ID in the control file is not the same as the // mount ID in the control file used by the first instance to // mount this database. The control files are for the same database // but they are not the same files. Most likely one instance is using // a backup control file. // *Action: Check that the correct control files were specified. [root@raclhr-11gR2-N1 ~]# oerr ora 202 00202, 00000, "control file: '%s'" // *Cause: This message reports the name file involved in other messages. // *Action: See associated error messages for a description of the problem.
感觉还是控制文件的问题,于是自己查看了备库的pfile文件,发现里边少一个参数db_unique_name,加上该参数后,问题解决。
