Sabarna,
This could be an issue with your restore script - is it in format below?
run
{
allocate channel t1 type 'SBT_TAPE' parms
'ENV=(NSR_SERVER=server,NSR_CLIENT=client,NSR_DPRINTF=TRUE, NSR_DEBUG_FILE=/nsr/applogs/t1.log,NSR_DEBUG_LEVEL=2)' ;
release channel t1;
}
I think you may have send instead of parms in the script.
If so please amend and retry.
Regards,
Bill Mason
Hi Sabarna_Deb,
If you are performing directed recovery , make sure that the communications between the two clients is perfect , also check the hosts file on both clients, to make sure that there is entries for each client's hosts file to the other client.
Otherwise if you are recovering to the same machine, I believe the issue will be in the restore script as mentioned by William Mason in the previous post.
Thanks,
Ahmed Bahaa

Actually in backend, few RMAN backup sessions was running from stopped backup which makes controlfile inconsistent therefore controlfile is referring to some other database files which dosen't belong to latest full backup. I put all incomplete saveset in 'recyclable' mode and started fresh database full backup. I believe this time we should complete restoration. I will let you the result. Thanks for your valuable reply.

Last time also restore database failed. Then we did crosscheck backup; post restoration of control file
Sample script:
RUN {
ALLOCATE CHANNEL CH1 TYPE 'SBT_TAPE';
SEND 'NSR_ENV=(NSR_SERVER=Backup server,NSR_CLIENT=client)';
Crosscheck backup;
RELEASE CHANNEL CH1; }
Restore and recover database completed successfully.
