Backup of Oracle8 database finished with error.
1. Check OmniBack II errors and follow OmniBack II
troubleshooting procedure.
2. Check Oracle8 RMAN errors.

How to troubleshoot or any limitation ?

Thanks in advance,

Hi,
if you are using OmniBack, I believe that the number of concurrent tape drives is limited in your license.

Hi,

I have 61-250 library extension license.

Hello,
I do not think, the concurrency is limited by license. Do you have a little bit more of error messages. I had a similar problem, when I had kernel parameters low for shared memory (this was on Linux).
May be you need to assign more shared memory. Check your shm.... Kernel parameters.
Hope this helps
