Hello,

I am facing a dead backup with msgno ANR0487W...

Unfortunately, the product lacks any way to assign a preemption-
governing priority to sessions: the preemption scheme is immutably
hard-coded into the architecture.  See "Preemption of Client or
Server Operations" in the Admin Guide manual for an overview, and the
one option you have to prevent preemption of backups.
