Thanks a lot roman ,it working fine.
i am doing new rman setup in my environmental.please advice if need any change the below setup,
# additional parameters for RMAN
# rman_channels and rman_filesperset are only used when rman_util,
# rman_disk or rman_stage
# rman_channels defines the number of parallel sbt channel allocations
# rman_filesperset = 0 means:
# one file per save set - for non-incremental backups
# all files in one save set - for incremental backups
# the others have the same meaning as for native RMAN
# rman_channels = 1
# rman_filesperset = 0
# rman_maxpiecesize = 0 # in KB - former name rman_kbytes
# rman_rate = 0 # in KB - former name rman_readrate
# rman_maxopenfiles = 0
# rman_maxsetsize = 0 # in KB - former name rman_setsize
# additional parameters for RMAN version 8.1
# the parameters have the same meaning as for native RMAN
# rman_diskratio = 0
# rman_pool = 0
# rman_copies = 0 | 1 | 2 | 3 | 4 # former name rman_duplex
# rman_proxy = no | yes | only
# special parameters for an external backup library, example:
rman_parms="ENV=(XINT_PROFILE=/oracle/sid/112_64/dbs/initsid.utl,PROLE_PORT=57323,&BR_INFO)"
# rman_parms = "BLKSIZE=65536 ENV=(BACKUP_SERVER=HOSTNAME)"
# rman_send = "'<command>'"
# rman_send = ("channel sbt_1 '<command1>' parms='<parameters1>'",
# "channel sbt_2 '<command2>' parms='<parameters2>'")
# rman_compress = no | yes
# rman_maxcorrupt = (<dbf_name>|<dbf_id>:<corr_cnt>, ...)
