Re: IMS v9 on z/os 1.13
Thanks to all those that replied. Good to know we aren't the only ones! We lost our IMS guy (retired), and are unlikely to replace him. I've never done an IMS upgrade, so rather than rush into it, I'm probably going to upgrade z/OS 1st, and approach IMS with caution!

Re: IMS v9 on z/os 1.13
I would suggest checking the IMS-L Listserv and the history of this sort of question. There have been changes to both z/os and IMS access methods over the years. IMS makes heavy use of VSAM shared services once called the VSAM DC option. IMS also has its own zOS access method known as OSAM (Originally Overflow Sequencial Access Method designed to replace ISAM overflow but now used by IMS for something else) These access methods are very z/os service sensitive. The more you use IMS the more you are exposed. I would not pay much attention to ISVs who claim that they run many historicial version of IMS under zos 1.13. They tend not to run them with high volume complex workloads and also do not really do any mesurable work on a day to day basis.

Re: IMS v9 on z/os 1.13
It all depends but In general IMS upgrades are easy as IMS is not tightly bound to the data. The first upgrade beyond V9 is often not easy. It was at V10 that IMS required security to be managed by an external security package like RACF. Prior to that IMS internal security called SMU was an option as well as default security. As an historical asside many early IMS shops did not use default security because it was too restrictive. An IMS upgrade beyond V9 is difficult to the extent that SMU is used.

It's generally quite straightforward to upgrade versions, you can skip versions when you upgrade, the newer versions pick up substantial CPU efficiency improvements, they're supported, and the new functions are often interesting. What's not to like? My 2 guesses: 1) IMS is behind along with other software (so you might as well ask why all that other software is behind also). 2) Red Headed step child - I suspect in shops where IMS is as important as DB2 and CICS they don't tend to run (as far) behind. My experience at several shops has been #2. Not much production IMS, not much expertise left or people who care to get it upgraded, so it is an after thought.

IMS v9 on z/os 1.13
Hi all, Is anyone out there running IMS V9 on z/OS 1.13? I know IMS v9 has been out of support since 2010, but that's where we are. I can see from the IBM site that V10, 11 12 of IMS will run on z/os 1.13, but not v9.

Re: IMS v9 on z/os 1.13
I know of a client site where V9, v10, V11, and V12 are all in concurrent use under z/OS 1.13. It has been unproblematic except on the occasion of one operator error, which has not been repeated. --jg On 8/20/12, Bob Shannon bshan...@rocketsoftware.com wrote: Is anyone out there running IMS V9 on z/OS 1.13?

Re: IMS v9 on z/os 1.13
As long as you have the most current maintenance available for your IMS release, it should work without problems. We currently have customers all the way back to V8 running under z/OS 1.12 and 1.13. None of them have any release related issues with IMS.
