Database Software

Hello Gurus,

I am using oracle 9.2.0.6 for my production database of size 800+GB. We are using RMAN for backup using netbackup (Symantec). I am facing errors while taking full backup, it was happened as ….

In past backup was happened properly, infact I restore the same database last year from the backup took. All was well until last month, suddenly my backup was failing, and when I contacting my vendor for backup failed they mentioned modifying the backup script.
After changing the script successful backup was done only once. It is throwing error as below.

It was able to backed up few DB files, later it breaks and throws errors. Using same script I can take successfull backup from the my end, while it failed when executed from netbackup server.
