Hello
I believe you are using a TSM storage solution for the database backups.
In that case you need to first make sure that the target server is able to communicate with the TSM server.
For that you may contact the TSM specialist to plug the target server for the database restore.
Once that is done you need to copy the files used by the backup from the source system to the target system.
Files required are : .utl, .sap (located at /oracle/SID/112_64/dbs), backup logs including the backupSID.log (located at /oracle/SID/sapbackup), TSM password/config file.
Once they are copid to the target system you can start the restore with the brrestore tool.
If you are using an online backup the you need to restore the archived logs as well to recover the database.
Regards
RB
