IBM has said the following -- IBM has tested TSM with AIX 7.1 and it also was shower for the DB backup performance. The TSM ATS Performance team has had other customers report this same problem and they resolved it by down leveling AIX to level 6.1.6. You can test a higher AIX patch level other than AIX 7.1 and if you get good DB backup speeds, please let IBM know. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of Remco Post Sent: Wednesday, March 21, 2012 2:21 PM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] Slow TSM DB Backup Update #3 Hi All, is there an APAR, or 'just' a PMR?
