CICS EVENT PROCESSING

Michaelod · New User Joined: 02 Sep 2008 Posts: 49 Location: Edinburgh

When a region is COLD or INITIAL started the default is to START event processing in the CICS region.

When WARM or EMERGENCY the last known value is used from the previous session.

Is there a way to disable event processing on a COLD or INITIAL start e.g using a SIT parameter etc?

If you are able to disable event processing it will be on COLD or INITIAL or WARM or EMERGENCY.

If there was no COLD or INITIAL first, there could not be a WARM or EMERGENCY. So, you want no "event processing" at all, or what, exactly?

I want no event processing at all......when the region is cold or inital started I want it disabled.

OK, google came up with lots of stuff, I don't know from that what is relevant to your set-up, but have you looked? What about your CICS sysprog?

Maybe this can help you :

had a look at google......from what I can see it seems that event processing is started as default. Can't see anything that suggests there is anyway to override it in the SIT.

CICS sysprog unsure.

Did you look at the specific link Peter provided? Why are you concerned about where it can be disabled, rather than whether it can be disabled, or to put it another way, why are the links no good to you?

the TS was referring to the fact that ( as per CICS manuals )
on a NOT<cold/initial> CICS start event processing status is what it was at CICS <shutdown/termination>
on a <cold/initial> CICS start event processing status i<started> by default

most probably no googling will change that

worth looking at the IBM support packs to check if there are any tweaks for it

I did look at the link Peter provided. I'm running version 4.1.

I did try to look at the adapters and get the following error:

CNX0624E: Get EP Adapter from "CICSE1" failed
CNX0221W Resource type 'EP Adapter' (EPADAPT) unsupported

I'm not concerned where it canbe disabled......just want to know if it can be.

There is a manual devoted to describing the SIT parameters and their use. If you have not read this manual, start with CICS TS 4.1 Info Center, open the CICS Transaction Server for z/OS, version 4.1 drop down, find the Configuring drop down, and you will find the SIT parameters.. If you have read this manual, then you should have no reason to post on this forum because you would know whether or not there is an SIT parameter to do what you want to do (hint: if you didn't find anything, that may be a clue that perhaps there is no way to do it the way you want).

The SIT was only an example......I was wondering if there were other ways.

I was looking for a quick answer as I dont have time to sift through manuals.....the orginal google search wasnt helpful.

I'll ask IBM as no one here seems to have anything constructive to say.

Apologies for wasting your time.

Mmmm... you don't have time. You don't have a CICS sysprog who can find out. So you expect us to step in and help out your company for free.

Then you give up on the board even before many of those contributors across the Altantic are at their workplaces. OK.

I haven't given up on the forum.

I just don't see the point in people adding their tuppence worth if they have nothing of value to add.

There are a few CEMT commands for event processing :

CEMT SET EPADAPTER
CEMT SET EPADAPTERSET
CEMT SET EVENTBINDING
CEMT SET EVENTPROCESS

With the help of automation these commands could be used to start, stop etc. event processing.

In the CICS Explorer, the EP adapter operations view provides a functional equivalent to these command.

No - I thought someone may have known off the top of their head - or at least point me in the correct direction (Thanks Peter btw)

Also - thanks for the warning - can I ask what its for exactly?

PeterHolland · Posted: Mon Mar 04, 2013 7:41 pm

Probably your attitude is considered condescending.

Unless this function can be overridden via an Assembler program, which addresses the SIT, then EVENT processing (Yes/No) will be obtained from the CICS Global Catalog as an inherent part of the internals. However, I don't see a SIT option to activate/deactivate EVENT processing, regardless of how the region is started. I also don't see a CEMT override nor a System Programming API override, although Peter pointed out CEMT SET EVENTPROCESS, which has its possibilities. But, take a look at CECI as I could have glanced over it?

Even if there was a SIT option, that necessarily doesn't mean a user-program, which addresses the SIT, can override this value.

For example, SIT label "SITTRDUX" (tran-dump maximum as a hword), even though it's defined to the DFHSITDS DSECT (and not available to any API), is read-only and can only be changed by manually updating the SIT and recycling the region.

Perhaps a query to IBM may shed some light?

Thanks Bill

I've submitted an IBM query.

I'll let you know.
