Mainframe, MVS and zOS Discussion

utkarshDoes that mean that all the steps of a JCL would still execute even if the any step gets an abend?


When using IKJEFT01, it's only the abend which occurs within that TSO step which gets caught and turned into a CC 12. Any other program running outside of IKJEFT01 would have their ...

If that's how it works, then why do they keep on saying to migrate away from mainframes to have a connectivity with front end? In the name of mainframe migration?

Thanks. I was just trying to learn PL/I my own.

Not sure if we can practice PL/I at home? Are there some ways to create an environment?

There are three ways to call TSO. They differ in the error handling. 

zum13Hello.

Most of the COBOL/DB2 programs that I have seen running make use of the DSN interface under TSO, i.e. they are invoked like this:

//STEP1 EXEC PGM=IKJEFT01,REGION=0M
//STEPLIB DD DISP=SHR,DSN=DSNC10.SDSNLOAD
// DD DISP=SHR,DSN=DSNC10.SDSNLOD2
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD ...

Hi,

I have a cobol db2 program abending in S0C7 at the first step but the job returns CC=12 and continue to run the next step instead of stopping at first step.

Anyone faced this issue?

Hi,

I have a very basic question on CICS web-services, what are CICS Web Services? What is that thing which we could not do if they were not available to us?

I looked at documentation but that does not seem to answer this question specifically or I seem not to understand this.

Would appreciate if ...

Thanks zum13 for the great explanation, this helps a lot. I have a question on CICS web-services also, but I think I should create a new thread for it.

Thanks Anuj and Robert. That project was scrapped though we started working on it again.

SSH didn't work. Our mainframe sandbox is ZD&T. Will that make a difference?

zum13Hello.

There are other utilities available that are designed for the handling of VSAM files which are attached to larger products intended to make the files more usable and accessible from ISPF. Compuware's FileAid is a good example of this. While better known for the ISPF interface, it does ...

Thanks Robert. This blog from this website also helps me: https://zmainframes.com/zlog/check-poin ... planation/

Hi,

Could any one answer this question

How do you use checkpoint in cobol program?

Thanks Robert. Never thought a DNS look-up could be required in mainframes too.

Thanks zum13. This is working, will do more test.

I asked one of my known, he said run any command of CICS in batch, capture the return code, if it fails, region is down, like you said.

Is it common to run CICS commands in batch? Even if not, how can we run a CICS command in batch?

Usually 2 to 3 weeks they take. You should write an email to the hiring HR, they should help you.

Thanks zum13, this helps a lot. Understood.

How does this lookup for IPv4 and IPv6 applies to mainframes? Do they?

Thanks zum13.

But this is very expensive specially when you earn in rupees. Not sure if we can ever create an environment for personal learning.
