The TCB and JSCB control blocks are in the private area of the ASID - therefore any external monitoring application will have to use cross-memory techniques to access their contents.
I do not think that there is an easy way to determine in non-xmemory mode if an ASID has been started under MSTR or JES - however I would suggest that you examine/compare the contents of the JSAB control block for an ASID that has issued the "Request JOBID" SSI call (eg Netview) against a ASID that did start under the JES subsystem - maybe there are fields that are not populated for the first case?

Checking if you have a jobid or not is not a good solution. For jobs running under a subsystem, I get the job step TCB, then TCBJSCB, then JSCBSSIB. Field SSIBSSNM has the controlling subsystem name (and SSIBSUSE points to the SJB). I don't recall whether I ever looked at this for a SUB=MSTR start job, but all the control blocks are standard, and you should be able to run a quick assembly to get the offsets and values for REXX coding.
