RMAN to NAS & SSD steps ::
-------------------------------------
-------------------------------------
RMAN to NAS tests:
1) Check RMAN configs to remove RATE parm if any
2) Check to insure MAXOPENFILES parm and MAXSETSIZE parm are not in place
3) Reduce RMAN channels to 1 ( to get a base line number)
4) Leave FILESPERSET at default level, which is 64.
5) Perform backup/Observ backup time
6) Iterate the above steps 1-5 modifying RMAN channels to 2, 4, 6 etc
7) Check default # of write buffers/count & Perform restore operations and note Restore time.
8) Increase write buffers/count and perform Restore operation & note time.
RMAN to SSD:
9) Switch RMAN to point backups to SSD
10) Set #of RMAN channels set to 1.
11) Leave FILESPERSET at default level, which is 64.
12) Perform backup/Observ backup time
13) Iterate the above steps 1-5 modifying RMAN channels to 2, 4, 6 etc
