Netbackup , TWS and RMAN
DB version: 11.2
OS : AIX
I have joined a new company where RMAN backups go to Tape using Veritas Netbackup and these backup jobs are scheduled using IBM TWS (Tivoli Work Scheduler).
Prior to joining this company, I have only worked with RMAN using crontab.
I realise that Veritas Netbackup is just a middle man between RMAN executable and the Tape. But I can see Netbackup parameters like NB_ORA_POLICY being created for the server hosting the DB. When I googled NB_ORA_POLICY , I learnt that it is related to schedules of the RMAN backup (on which day should the Full backup should run , on which day should the incremental backup should run , etc...).
So, what is the role of TWS work sheduler if we are specifying the schedules in the Netbackup?
