Hi All,
I am looking for your guidance on how to handle SAP backup which is working through RMAN, it is taking almost 18-20 hours to complete the backup, database size is 3.5 TB.
I am using RMAN channel 2, I am looking for a option to set below option to speed up the backup process.
Multiplexing- For me i guess tsm doesn't support.
Parallel Session- I can see through BRtools i can use this but on which i am using RMAN_util it is not working
I am not able to see option where to update this while using RMAN_UTIL
Parallel sessions :
Multiplexed files :
Buffer size :
if any other parameter which i am missing please advise that as well, backup is happening through STA, that is why i am not convince it is taking that much time.
SID.sap few details.
# number of members in RMAN savesets [ 1 | 2 | 3 | 4 | tsp | all ]
# default: 1
saveset_members = 1
# additional parameters for RMAN
# rman_channels and rman_filesperset are only used when rman_util
# rman_channels defines the number of parallel sbt channel allocations
# rman_filesperset = 0 means:
# one file per saveset - for non-incremental backups
# all files in one saveset - for incremental backups
# the others have the same meaning as for native RMAN
#rman_channels = 1
rman_channels = 2
# rman_filesperset = 0
# rman_kbytes = 0
# rman_readrate = 0
# rman_maxopenfiles = 0
# rman_setsize = 0
# additional parameters for RMAN version 8.1
# the parameters have the same meaning as for native RMAN
# rman_diskratio = 0
# rman_pool = 0
# rman_duplex = 0 | 1 | 2 | 3 | 4
# rman_proxy = no | yes | only
