I wanted to know the IMS version which allows working with REXX. Currently, I have IMS 8, which does not support REXX. What should be the minimum version for this??

Thanks for the reply..
I did search the net for this, and I got information regarding IMS 11 & IMS 10. Only thing that I was not sure about was that which version it starts from.. My MF admin was also not sure about that, hence this post..

Rexx SPOC is comparatively new, but REXXTDLI and REXXIMS (application programming interfaces used to access IMS data bases and message queues) have been around since at least the early 1990s.

It is odd that you should say that... can you explain what does not work?

Well, I am sorry for my limited exploration in this regard.
Recently, I tried to establish connection with IMS and perform some basic operations, but could not do that.... May be I didn't do correctly.
I contacted my admin for assistance, in case I require some settings, that is when he told it's IMS 8, & we may not be able to work with REXX. Probably, he was talking specifically about our installation....
I think I should go through the manuals in detail & try again. However, any specific/general guldelines to have a good start will be helpful.

PS: I have experience of working in REXX, but not much with IMS DB.

"I tried to connect." is not sufficient for us to provide much assistance. Perhaps provide your rexx program if it is not very long.

What are you trying to do? The REXX SPOC has not much to do with IMS DB. The REXX SPOC has to do with issuing IMS operator commands for automation purposes.

If you are trying to use the REXX SPOC, you should know that there is some work required to enable it. You cannot decide on your own to start issuing IMS operator commands. There needs to be some amount of planning, configuring, and administration.

There are additional started tasks that need to be configured and started. You need the Operations Manager (OM), and Common Service Layer (CSL) started tasks.

You need OM, CSL, and IMS to be configured to specify the same IMSplex name in their startup parameters. Also, the rexx program needs to also specify the same IMSplex name.

And you probably need RACF permission to use the IMS loadlib and further RACF permissions to issue operator commands.

In V10, the manual to read is "System Definition Guide", but I think it had a different title in V8.

Enrico provide some links to the book server, but the book server seems to have changed and now seems awkward to use.

Try this:
http://publib.boulder.ibm.com/infocenter/dzichelp/v2r2/index.jsp

fyi, I noticed this there:
Quote:
IBM® discontinued support for IMS™ Version 8 on November 5, 2008.

Though, there is a link to the discontinued manuals.
