Nagaraj,  

From the looks of erros below, you have not had a successfull archivelog backup. This is because you deleted/compresses the archive logs before they could be backed up by RMAN. You need to run "crosscheck archivelog all" before running RMAN backup. So that RMAN knows about missing/deleted archivelogs, and can successfully backup all archivelogs generated during RMAN backup.  

Regards,
Vishal Gupta

        Check your alert log for the time frame when the backup was running. If you cut archive logs during the time frame the backup ran (start until finish inclusive), you must have them to recover the database. I don't believe the database will open if you cut logs during the hot backup and don't have them for the recovery. (What happened with your archive logs?)          

        If you have not done anything in this database since your backup, and no new archive logs were cut, you may get lucky and be able to use your on-line redo logs as the logs that it wants for the recovery.
