RMAN-20512: source database already registered in recovery catalog

RMAN-20512: source database already registered in recovery catalog
Cause: Source database was already registered in the recovery catalog.
Action: If the source database is really registered, there is no need to register it again. Note that the recovery catalog enforces that all databases have a unique DBID. If the new database was created by copying files from an existing database, it will have the same DBID as the original database and cannot be registered in the same recovery catalog.

RMAN-20512:源数据库已在恢复目录中注册,
.原因:源数据库已在恢复目录中注册。,
.操作:如果源数据库真的注册,则不需要再次注册它。请注意,恢复目录强制所有数据库都有唯一的DBID。如果通过从现有数据库复制文件来创建新数据库,则它将具有与原始数据库相同的DBID,并且无法在同一恢复目录中注册。,
