Hi Steff, Please look at JES2 Exit 4 (There is a sample in CBT File 122) and (SMF Exit) IEFUJV (There is a sample in CBT File 573). Regards, David On 11/10/2024 15:51, Steff Gladstone wrote: What is the best way of modifying JCL after the job has been submitted, in order to conditionally add

Re: Old ISPF application scripting from batch?

This might be overkill as a solution but you could use CEA TSO/E address space services to start TSO/ISPF: https://www.ibm.com/docs/en/zos/3.1.0?topic=services-introduction-cea-tsoe-address-space then use the

Modifying JCL on the fly

What is the best way of modifying JCL after the job has been submitted, in order to conditionally add another DDNAME to a JOB STEP? Or perhaps adding parameters to the PARM string on the EXEC statement. We were thinking of using the IEFUSI exit point, allocating a file dynamically before the mai

Re: Modifying JCL on the fly

You can't, but there are some things that you can do on the fly. You can allocate and free datasets dynamcally with SVC 99, either directly or using one of the IBM provided front ends. e.g., ALLOC, BPXWDYN. You can do a RDJFCB, modify, e.g., the member name, the file sequence number, then OPEN

Re: Modifying JCL on the fly

Submit an additional job with the same jobname. Be sure to delay a little bit until the first job is running.. On Sun, Nov 10, 2024 at 3:51 PM Seymour J Metz wrote: > > You can't, but there are some things that you can do on the fly. > > You can allocate and free datasets dynamcally with SVC 99,

ADRVCMPT

Hi, ADRVCMPT is a relatively new tool that estimates how compressible data on a volume is using zEDC. It can be installed using APAR OA66417 for z/OS v2.5 and v3.1. Is there a way to run ADRVCMPT on multiple volumes in one job? Thanks Gadi --

Re: Question about WAIT and POST.

I think that Binyamin's point was about RB's within a task. For example, if your PRB was waiting on "ECB-PRB" and an IRB popped on that same task while the PRB was waiting and the IRB itself went into a WAIT on "ECB-IRB", the task would not be woken up upon a post of "ECB-PRB". Now that you have

Re: Modifying JCL on the fly

Short answer: NO WAY. However you can use some *programming* language for that, including REXX. Simple explanation: JCL is *not* a programming language. JCL "piece of code" is called job, not program. The job could be compared to a command entered from command line. Indeed, simple single-jobstep
