Hello all,

I would like to ask for help regarding an Oracle backup with an
external tool (CommVault).

This is an 11gR2 database with approximately 70TB and 4 nodes
When backup is invoked via CommVault the backup takes around 2h to
start (between the allocation of channels and  “start backup”).

I would like help on where should I look to find the cause of this behaviour.
I also want to point that other databases in the same Oracle home
don’t show this behaviour.

Thanks,

Arestas
