Rman backup fails..
hello,
For some odd reason, i have getting this error while backing up the database from past 2 days. Was not able to find anything good online. We are using TSM(tivoli) as our MML.... Database has allways got backed up fine...this just started 2 days ago...any suggestion?? This is 10g on AIX...it looks like it start the backup and this occurs around when half the database gets backed up...is this something towards the database or tivoli ??? And also not to mention...the archive logs get backed up perfectly fine..its just the database backup that fails with these errors....THANKS
