The only way that I am aware of (and I had to write this exact function for the MXI G2 CICS plug-in) is to loop thru the TCBs in the suspect address space hunting for the AFCX control block which is pointed to by TCBCAUF. To do this you need to squirt an SRB into the suspect ASID and recover from any 0C4s (and other nasties) that you are going to get snooping around.
It helps *hugely* if you have some site knowledge that narrows down the list of possibles by using one or more patterns in the Jobname and/or some of the WLM classes (service, report or workload). Also be aware that CICS control blocks sometimes wear their "I LOVE JES2" t-shirts and enjoy shuffling fields around and changing offsets between releases - so any code you write in x-memory mode for CICS needs an "offset table per release" approach.

By identifying, I mean programmatically. As an example of what I'm talking about, to locate DB2 address spaces, a search of the SSCT chain is done to find an SSCT with a pointer to a DB2 ERLY block. Once that is found, the DB2 system name is known, and the address spaces that make up that instance of DB2 can be located. Is the technique for CICS similar? I would appreciate any help one can provide on this. Thanks in advance. --Dave Day ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
