Mainframe, MVS and zOS Discussion

Hi Robert, Thanks for the answer. Please allow me some time and I'll post the required information. We have recently upgraded to CICS v5.5 and I have been told that it supports container / channel. I am not very familiar with this concept and I did some reading online about it but I don't feel like ...

Hi, I've a CICS program in which there is a value which I'm writing to TSQ. This value I need on next 'start' of the program but some where in the program this value, which is a flag, is getting lost when I read the TSQ again. Ideal logic is that I figure out that why data in TSQ is getting initiali...

Hi Friends, I've a huge table in production. Which I need to unload. It's taking a lot of time to unload this table. I thought to unload it in 'pieces' like unload some rows of it then rest of it. To do that, I used FETCH FIRST nnnnn rows from the table, this is order by a column. But now how do I u...

Hi, What is the use of DBCTL in IMS DB? Does DBCTL defines the database? We have 3 DBCTL in production but in previous it was only one. What is the benefit of having more than one of them? I read about it but don't understand it. Can someone please guide? [ Post made via Android ] https://www.zmainf...

Hi,

If I need to copy a VSAM file to another VSAM file where I change the name of the output VSAM. In doing so is there a possibility to copy the input VSAM attributes to output VSAM? Just like model DCB parameters?

Hi, When should we think about using pointers in COBOL? Is there a situation which can not be solved without pointers? I did look at some documentation https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_72/rzase/dfinpnt.htm but I am not sure if I got the answer yet. Could someone please share ...

Thanks Robert.

Thanks, will look in that direction too.

May you are right that there is a lot of misperception about it. In our company they waned to develop microservices outside legacy platforms, that's the only statement we hear.

Hi All,

Though it is possible to develop microservices on Mainframes as well as as400 why is it that customers are wanting to develop microservices outside legacy platforms rather than doing it within IBM i or IBM z

Any answers would help.

Hi, Can any one suggest how to access jobtrac using REXX or jcl?

Purpose: I want to extract the list of abended jobs from scheduler

Does anybody know what should be the data type for the return value of timestampdiff function when it is using In COBOL?

Hi,

How and when we make use of SYMNAMES in SORT?Could anyone please explain it to me. I dont' get it.

16792 WS-C1 is a penalty and will always be numeric You REALLY need to learn COBOL rather than spouting off about things you have no clue about. In the code you posted, WS-C1 is PIC X(4) and starts the program with spaces in it; spaces are NOT numeric and hence your statement I quoted is TOTALLY BO...

Actually the real problem came in when I started looking at an existing program. The code is something like this: 05 WS-PENALTY. 10 WS-C1 PIC X(4) VALUE SPACES. 10 WS-C2 PIC X(2) VALUE '00'. 05 WS-PENALITY1 REDEFINES WS-PENALTY PIC 9(6). . . . CALL 'A-TABLE-ROUTINE' USING TBLE-VARIABLE IF TBLE-RESP ...

Hi,

Will checking a variable like

WS-VAR > 0 and

WS-VAR > ZEROS

will yield the same results? When WS-VAR is defined as PIC (X)?

I could not tell it well what I wanted to ask but that is fine. Thanks for the answeres.

Thanks Robert and William. I did some reading online about it and one of the place it was written like this in support of wait and it confuses me whether or not wait is a good option in COBOL batch or COBOL-CICS: maybe you want to switch the CICS dump data sets or perhaps start an online transaction...

14159 Is this a CICS or batch program? If CICS you could start the transaction with an interval. If batch, this is a SPECTACULARLY BAD DESIGN. Batch programs should NEVER wait -- you are tying up system resources with such a design. And there is no facility in COBOL to do such a wait (which SHOULD ...

Thanks forthe answers.

I was talking about zOS as "base software". As UNIX is written in C.

And was curious to know about COBOL too that in what language it is written?
