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:

[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。
