It's been a while, but perhaps I can help. Unlike CICS, IMS is not normally conversational. You enter a transaction and IMS moves it from queue to queue until the unit of work is complete. If the transaction so chooses, a reply of some sort may be sent back to the entering terminal.
It is reasonable to suspect that one or more resources are not available and the transaction is waiting in some queue. It's been too long for me to be able to suggest ways to identify what resources may be causing the issue. I seem to recall some sort of detailed report (DC Monitor?) that can be activated. But it is also reasonable to suspect that the transaction has simply not sent anything beck to the terminal. As I recall, the most basic form of a transaction was to clear the screen, then enter the transaction name. The transaction would then send a formatted reply to the terminal. You can pre format the screen with a /FOR command if you know the format (message output descriptor or MOD) name. I've never had occasion to use the /SET TRAN command. If you are finding that you have to use it, then perhaps the screen is being formatted without the transaction name as the first eight bytes of the input message. Having some experience with both CICS and IMS, I would not say that one is any easier to use than the other. IMS may be a bit more complicated, but it tends to scale well. HTH and good luck. -----Original Message----- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of David Logan Sent: Wednesday, May 20, 2009 9:09 AM To: IBM-MAIN@bama.ua.edu Subject: "CEDF" type of ability in IMS?? Thanks all to those who helped me get through step one in IMS. It's pain in the butt, a lot of stupid little pieces and parts and steps, but it's not that hard once you know what the pieces and parts and steps are. I got one of my two transactions working. However, the other one still isn't, and I see no obvious reason. No messages or anything. So my question is this: Is there some type of debug/log ability in IMS (perhaps similar to CEDF in CICS)? Is there an easy way for me to tell that it may be trying to access a DBD that doesn't have a file or something? I don't know why it just ignores me when I type the transaction in. As a secondary question, now that I'm thinking about it. My developers appear to be used to logging onto IMS, signing in, then just typing the transaction. Currently, I have to do a /SET TRANSACTION XXX" before I can type in XXX. What is the magic to not have to do the /SET first? Thanks!
