Mainframe, MVS and zOS Discussion

Yeah, perhaps, i was not selected for that round...

At age 5 his Father died. At age 16 he quit school. At age 17 he had already lost four jobs. At age 18 he got married. Between ages 18 and 22, he was a railroad conductor and failed. He joined the army and washed out there. He applied for law school he was rejected. He became an insurance sales man ...

When you talk about "dummy utilities", remember the following:  IEFBR14 does not open the DD, so it's good for deleting, but not for allocating. Use IEBGENER with SYSUT1 dummied and SYSUT2 with the correct DCB. Gene So did you mean there are other universal utilities from IBM which can be...

I've never hard of IEFBR14 being called "the dummy utility". I'd have done exactly the same as Ankit. Although perhaps I'd have said a little more at the end. Everybody and their dog has used IEFBR14, and any site that thinks they've got a cool cutesy name for it, and that someone who is ...

IEFBR14 called as dummy utility because it almost do nothing. Please refer the link https://www.ibm.com/support/knowledgecenter/zosbasics/com.ibm.zos.zdatamgmt/zsysprogc_utilities_IEFBR14.htm Thanks, Chandan I saw that link but I could not find if dummy is used somewhere to refer to IEFBR14, offici...

I've never heard IEFBR14 called the dummy utility, but I can see the term being used.  IEFBR14 consists of a BR 14 assembler instruction, so all it really does is return to the calling program (usually the operating system). Thanks Robert. May be because of your experience, you can see it being use...

I searched on it and most of the results says that some tools other than from IBM can do it, but it's like similar in DB2 I think. SOme of the link which I looked at are here: https://www.ibm.com/support/knowledgecenter/SSS8QJ_2.1.0/com.ibm.imstools.bbe.doc.ug/topics/bbe_ovvw-whatis.html http://www....

Interviewer: What is a Dummy Utility and what it does? Ankit: :? What is dummy utility, can you please elaborate ? Interviewer: So you don't know about it? Ankit: I might but may be I don't call it dummy. If it's a utility itmust be doing something. So word dummy confuses me. What exactly you are as...

Hi,

Do we have the concept of REORG in IMS DB same as in DB2? Does it have the same impact on the dataase? How do we do REORG in IMS DB? Please guide me on this.

Thanks for the welcome...

Thanks a lot Anuj.

Hi
Is there a step by step example of some example program in which it is shown to change/convert the cobol data into XML format and covert XML data back to cobol. It'd be nice if you can direct me to some sample program? Thanks,

The term "simulator" is associated with Hercules-390, which simulates a mainframe through software on a PC or Unix machine.  Given an operating system, a Hercules-390 machine acts very closely to the same as a mainframe (although there are differences). I do not know who made the associat...

Hi,

Is the concept of Emulator and simulator in mainframe same? If I say I am using a simulator to connect to mainframes or if I say I am using an emulator to connect to mainframes, do they carry same or similar meaning? I have seen many people using them interchangeably..

Thanks for the links.

Thanks Anuj!

Can you please give some answer for this too: "And when do we use it? Have you used in a real production environment, can you please give a practical example on it?"

What is Application Binding in CICS? And when do we use it? Have you used in a real production environment, can you please give a practical example on it?

It sounds like a nice idea but do you have something to show so that we can understand it better?
