I called IBM in yesterday to get an update to learn if TSM for z/OS was still destined for the scapeheap come 2013 and indeed it is. Although one can prolong its life by 3-4 years aftyer 2013 paying extra for extended support. The pitch is to move your TSM over to zLinux, AIX, Windows, etc. This is not appealing for a number of reasons why we went with TSM for z/OS; 99.999% availability, automation, operational advantages, use existing IBM VTS/ATL, tape management as a part of either RMM or CA-1, etc.
Back when I heard the annoucement a few years ago, the IBM party line I heard at SHARE each year (2 years running) was TSM was converting over to use DB2 as its catalog store. IBM had discovered using DB2 for z/OS would mean a spectacular performance hit and running on distributed systems using UDB/DB2 it ran like a bandit. Therefore it was DB2's fault and they had no choice. Yesterday the story was met with amazement and it has changed to no one was using TSM for z/OS and I was only one of "five" total. Therefore it was an economic decision (which if true makes sense). Also the TSM folks believe the world is going over to zLinux besides because of the big upswing in the number sold last year (probably very true). Question - 1: "SO" I would like to know who are the other four people who had a similar idea about using TSM for z/OS, to be the data backup place in order to leverage all the good things z/OS has to offer. Like to include those who in the last 2-3 years may have junked TSM for z/OS and went over to another methodology because of the IBM notion no is using the product. Call me a skeptical, but with all the sales emphasis done by IBM Tivoli, am I to believe for the last 5-6 years, all the z/OS installations in the world assaulted by teams of IBM'ers only succeeded in "5" TSM for z/OS sales. Question - 2: So what are people going to use to back up things like your zFS/HFS files on z/OS to get granularity in the restoring at the file level. And also if you are using Linux on z, what is the same backup strategy for the Linux file systems if one did not use TSM for z/OS. I hear for TSM for Linux Server to dump the zFS files on z/OS I run a TSM Client on z/OS and will need Open Systems Tape hardware like LTO specifically for the Tape drives used by TSM. Today I only have FICON IBM 3592 type drives for z/OS and z/VM dumps. So now I would need to buy hardware along with the TSM for Linux Server? You may respond onlist or offlist. Like to take a poll here and will publish the high level survey (no names or industries, etc) besides giving the information to the IBM TSM folks as either confirmation, etc. Jim Jim Marshall, Software Engineer Washington DC 20415 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
