Mainframe, MVS and zOS Discussion

Hi

Thank you Robert and Anuj. Is there some blog or documentation on this, that can be of help.

Thank you Robert.

But Anuj's this sentence

these are very personal choices and are endless - suggest your friend madidate - write down pros and cons, weigh them and takes a decision. Good Luck!

is very correct in this situation. Good you've a decision now.

Recently there had been very good hikes in salaries in mainframe. I am not sure why it happened in India? Anybody knows?

Does 3.3 alos calls IEBCOPY?

Congratulations, that's a very good salary.

You need to be careful here. IBM distinguishes between a data set which has never had any data written to it versus a data set that has been written to but has no records now. In the first case, you cannot read the data set so your application design fails. In the second case, there is no problem w...

Traditionally Mainframe applications development process made use of a(n) SCM tool. Many vendors provided and provides SCM tools, however, using a tool from a given vendor made a shop bound to that vendor. Using DBB makes it vendor independent - as far as adoption of other tools is considered - lik...

Different source code managers have different feature sets so there are differences between the different SCM. DBB has the advantage of working with COBOL and PL/I, which have been used on mainframes for more than 50 years. Not all SCM tools support COBOL or PL/I. So IBM DBB is a SCM tool from IBM?

May I request the answer again please.

I should have elaborated it. The situation goes like this: Open a file in the program and if the file is empty write header data and the details to file. However in case the file is not empty we need to write the details only and not the header. Is there any way to toggle between the modes within th...

Hi everyone,

I have a situation which requires me to open the same file in two different mode in a single COBOL program. Can we do that?

If you are still using PDS you could run out of directory blocks when adding members to the PDS. If this happens, and you don't have a recovery utility like PDS86, you will have no choice but to copy the PDS to a new PDS with a larger directory. PDSE don't run out of directory blocks, so one common...

Thanks Anuj.

But then what's the point of having such a complex tool? If the result is same as we have with any SCM tool?

Hi,

I read about IBM DBB, but I am not sure if I have understood it. Could anyone please explain it in layman language that how it' is used in mainframes and what are its advantages over regular mainframes?

Thanks for any reply in this regard,

If the experience is less than 10 years, you should accept the offer with more salary. Then later you'll have age on your side to change. In India, there are very very few job for mainframe experienced resources. I heard that only abroad, specially in U.S. mainframe programmers are getting retired b...

Thnks William. [quote"]How you get to go about the first part, you already know. Always check that the listing you are using to identify the offset is the same date as the program which failed. If you need to recompile, ensure that the offset at the very least shows the same instruction, and ve...

What are the reasons for which S0C7 comes and many programmers come out saying to look out for OFFSET ADDRESS and see the DUMP and trace the statement where SOC7 occured. But I wan to know, what is the actual procedure to solve SOC7 in general ? Is there any specific method available which can be us...
