Oracle Database Discussions

Im using RMAN to copy a database to another server. The new server is IDENTICAL to the old one. By identical I mean it has the same sever name, ip address, operating system, Oracle version and directory structure.

The new server already has the instance created, (same name as the old server instance, paths etc)

The backup files have been manually restored to the new server, same locations as they were on the old one. ( RMAN did an automatic controlfile backup and also the archivelogs on the old server ).

Ive restored the control file on the new server from the RMAN backup pieces.

Ive catalogued the RMAN backup pieces on the new server.

I know the last sequence available in the archivelogs backup by running on the new server :

So far its all going swimmingly well.

Now I want to restore the datafiles and recover. So I ran :

RMAN run { restore database; recover database; alter database open resetlogs; }

This gave me the output below which goes great but I get a final error, I think the error is because its looking for an archive log thats not in the backup set, but it should be. However, I think SCN 560851 is for a log that hadnt been created yet on the old server when the backup was ran ?

How do I address resolving the error ? Its worth pointing out log, "archive log filename=C:\ORACLE\PRODUCT\10.2.0\FLASH_RECOVERY_AREA\SAT\ARCHIVELOG
\2011_05_11\O1_MF_1_6_6WOK1X4W_.ARC recid=10 stamp=750881741" isnt on the old server either which is why its not in the backup set.

I can do a alter database open reset logs but Id prefer to know why its failing.


Any help would be much appreciated.
