Mainframe, MVS and zOS Discussion

Thanks Robert.

That link is very helpful, Thanks again.

Thanks giskard.

What can we use in place of ISPF in Hercules?

I read it. Not all of them it's too heavy as subject. But I could not make a simple question to answer, like why do we require this concept in CICS? Is it related to Channels/containers in any way?

How do I verify that? I am not sure, can you please tell?

Thanks for the explanation Anuj.

But then how come these many JCLs have ended all with the UNIT parameters at so many places? How do different companies handle it? And why were they coded with UNIT, at first place?

But if we still give a UNIT=DASD in the JCL, what's wrong will it do?

Do you have more such picture, the description in them is interesting for me. Can you share more pics or can direct me to a link to further exploration.

Thanks again for sharing them.

Thanks for the guidance. I have started learning it again.

I am also reading about Hercules, will Hercules allow to practice assembler or do we need purchase assembler license to practice it on Hercules?

Thanks giskard.

I work from offshore and storage support is not approachable for us at all. So I mostly reply on my own studies and website like this.

Hi I am new to CICS and queues. Recently I read that a queue is "remotely defined in the local region", what does this sentence mean? If a queue is defined in a CICS region, will not it be always local to it? How can it is defined in the region but is remote? Can someone please explain tha...

This is great piece of code, Thanks Anuj!

Was the first 360 chip so small? Then why mainframes were so big?

Thanks Robert. //S1 EXEC PGM=ICEMAN //SYSOUT DD SYSOUT=* //SORTIN DD DSN=TEST.MQTEST.ERRORS,DISP=SHR //SORTOUT DD DSN=MISZD2.TEST.MQTEST.ERRORS, // DISP=(NEW,CATLG,DELETE), // SPACE=(CYL,(5,5)),UNIT=SYSDA,RECFM=VB,LRECL=231 //SYSIN DD * OPTION COPY /* //* It worked.

Hi,

Do we really require SORTWORK files in a SORT JCL? I've seen it is working both the way, with or without them, so what si the rule? Please suggest.

Happy Birthday Mainframe - you gave us bread and butter!

Hi, Is there a way that using ISPF 3.4 we can locate only the GDG bases? I mean when I use wild card it shows the generations also. The problem I have is - I want to pick only the GDG bases - every base has got may generations for it - so it takes many iterations to reach to next GDGD base, if I cou...

Thanks Anuj. Your answer helps me to understand it. Thanks.

Hi, I know this is 2020 and there are not many jobs for assembler. But there had been some programs in our company which are written in assembler. They abend once in a while in production and becomes nightmare to solve it. I'd like to learn reading an assembler program and solving the abends for the...

Hi,

What is the difference between "Database" & "Legacy Data Store"? Are rhey just same?
