最近有个数据库的rman backup任务出错了,错误是 RMAN-20004
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20004: target database name does not match name in recovery catalog
在metalink上搜索的结果,Oracle说这是一个内部错误,建议开SR。
Error: RMAN 20004
Text: target database name does not match name in recovery catalog
---------------------------------------------------------------------------
Cause: name of the target database doesn't match the one stored in the
recovery catalog
Action: This is an internal error, call support.
经查发现有另外一个数据库与本数据库有相同的dbid并且在catalog数据库中注册,导致本数据库连接catalog数据库的时候报错。于是把另外一个注销掉,然后注册本数据库,问题解决。
