Important point needs to be consider while configuring RMAN for SAP BRTOOLS.
I had to configure RMAN for taking incremental backup of our SAP database by using RMAN.
Here i have mentioned point which helped me to connect BRTOOLS to RMAN.
create following link first after installing TSM service at OS host
ln -s /usr/tivoli/tsm/tdp_r3/ora64/libtdp_r3. /usr/lib/libobk.
ln -s /usr/lib/libobk.so $ORACLE_HOME/lib/libobk.so
Mentione device type as for taking backup through RMAN
Set rman_parms to identify brtools for TSM parameters.
Locate the appropriate ProLE port number in the /etc/services file. Look
for port name tdpr3ora64
Below parameters also need to set in initsid.sap parameter file
saveset_members = 1
rman_channels = 6 : This parameter defines the number of parallel channels used by RMAN with an external backup library, that is, backup_dev_type = rman_util
rman_filesperset = 8
Make sure /usr/lib is specified in the library path environment of your
