Have a TDP 5.4.1.0 running on AIX. The RMAN script does a backup of the
database, backup of the logs and then a DELETE OBSOLETE. From the output you
see the channel allocating fine and the delete starts working
until.BANG.ANS1033E Invalid TCP/IP Host. From the TSM server actlog I can
see multiple sessions start/stop for this delete obsolete. It looks like
RMAN opens/closes a session for each backup piece. So it's going along just
fine and then failing with a DNS lookup failure?? Any ideas?

RMAN> allocate channel for maintenance device type 'SBT_TAPE' parms
'ENV=(TDPO_OPTFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.opt)';
allocated channel: ORA_MAINT_SBT_TAPE_1
channel ORA_MAINT_SBT_TAPE_1: sid=502 devtype=SBT_TAPE
channel ORA_MAINT_SBT_TAPE_1: Data Protection for Oracle: version 5.4.1.0


RMAN> delete noprompt obsolete recovery window of 35 days device type
'SBT_TAPE';
