STEP 1
First Use BPLIST command with the time stamp of the First handle and time stamp of the last handle (Get this information from DBA)
bplist -B -C client_name -S master -t 4 -k RMAN_Policy -keyword database_name -s mm/dd/yyyy hh:mm:ss -e mm/dd/yyyy hh:mm:ss -R -l -u /
Above command should list out all the handles, important is the keyword which should match with the database name. Compare the handle Names given by the DBA and they should match exactly. If don't make sure timestamp is correct. If the names of the handles does not match with names from DBA list you cannot proceed further.
STEP 2-
Then use the BPIMAGELIST command with same time stamp
bpimagelist -client client_name -policy RMAN_Policy -keyword database_name -d mm/dd/yyyy hh:mm:ss -e mm/dd/yyyy hh:mm:ss -U
Above command should give similar number of image output as in STEP 1
STEP 3
Run the same command in STEP2 just add -media at the end and it should give you the medias required for the restore of the RMAN backup
bpimagelist -client client_name -policy RMAN_Policy -keyword database_name -d mm/dd/yyyy hh:mm:ss -e mm/dd/yyyy hh:mm:ss -U -media
