Both Informix and Oracle will have new XBSA libraries, so they both will need to be relinked.
Informix
1. No need to shutdown/restart Informix
2. No need to alter the $INFORMIXDIR/etc/sm_versions file
3. No need to alter the backup/restore scripts, or the ALARMPROGRAM
4. Install the newer Informix XBSA library (i.e. "/usr/openv/netbackup/bin/infxbsa.so")
5. ln -s /usr/openv/netbackup/bin/infxbsa.so /usr/lib/ibsad001.so
Oracle
1. No need to alter the backup scripts
2. Install the newer Oracle XBSA library (i.e. "/usr/openv/netbackup/bin/libobk.so")
3. ln -s /usr/openv/netbackup/bin/libobk.so $ORACLE_HOME/lib/libobk.so
4. Shutdown/restart Oracle
5. On AIX platforms, you probably will also need to run slibclean while Oracle is shutdown
Make sure that you've checked the support matrix for both. Informix is more forgiving for an unsupported configuration than Oracle. Good luck.
