Dear :
If you have to use EMC NW NDMA to backup oracle database and want to see what happen when backup failed.
You can use this wau and do not do that way.
Let use XXX as an example:
nsrdasv -z /nsr/apps/config/nmda_oracle_XXX.cfg
In that config file there two area need to attention.
NSR_RMAN_ARGUMENTS ="nocatalog msglog '/nsr/applogs/oracle_XXX.log' append"
If you go that way you can see backup log when each time start. But be careful ..

DEBUG PARAMETERS (for troubleshooting)

NSR_DEBUG_LEVEL =5

NSR_DIAGNOSTIC_DEST =/nsr/applogs

NSR_DEBUG_LEVEL: 0-9.

NSR_DIAGNOSTIC_DEST: /nsr/apps/logs (default). Location of the debug logs.

Do not enable debug model unless oracle support request you to. OtheRwise much much debug log will occupy log directory.
