Mainframe, MVS and zOS Discussion

Thanks Robert.

I did not mean to offend anyone but I wanted to learn if my way of thinking is correct. I understand that DASD is not that expensive now but it used to be. I wanted to know about the calculation and the implications. I understand it now.

Thank you.

your data set will put 42 records per track with a block size of 27300 as opposed to 23 records per track with a block size of 29900. How did you get these numbers? As far as your ISPF 3.2 session goes, I don't know exactly what you did but I suspect you put in the data set with a blank command to ...

Yes that I understand but is it the optimum BLKSIZE? And if yes, why it is?

COBOL program has BLOCK CONTAINS 0 RECORDS.

There was an abend in production which was because of LRECL mismatch. In that the production support person, as a workaround, changed the record length on all the steps that used that program and as well as the backup step in the job. They changed the blocksize from 27600 to 29900 saying that the ex...

Thanks all but does not any log capture such a thing which can be communicated automatically, is that possible?

About overriding parameters in JCL

In one step I am using multiple files (say 5 files)as input with single DD Name (SORTIN).
When I am overriding file using STEP1.SORTIN DD DSN= ; it is overriding first file

Is any possible to override other than 1st file ?

Hi, We have number of CICS test regions. And there are some common files which are allocated to these regions, used by all. We send email to tell everybody for a changing these files, before changing, but, many a times someone just changes it without notification. How can we find who is changing the...

I am sorry but I did not get you. You mean if the options appear in the above list, irrespective of the point whether they were supplied at compiler or binder does not matter?

I was working with the team involved in setting up the tool. They told me if the options shown the in the COBOL listing from CLIST and TOOL are same, we are good. As shown below: Is that correct, even when the we have difference in the JCLs generated as stated in the first post? PP 5655-S71 IBM ENTE...

Hi, We had been using a home grown CLIST to compile the COBOL programs of all sort. Now we have a new SCM tool coming in. we want to make sure that the compile JCL created by the CLIST and the new tool are same. While testing I found out that for a batch COBOL program these were the options: CLIST :...

Thanks. I was trying to analogy for understanding. If there were only CICS maps, could I say that 'panel group editor' is equivalent to MAPSET, as far as the functionality of it is concerned? I am asking this to understand it conceptually.

Hi, I've been trying to figure out What is the use of Panel Group in SDF 2 when we create the CICS map? Is not it equal to a CICS MAPSET? I looked in to the manuals, but it talks how to use it but does not tell what would happen if we don't use it and if can be compared with MAPSET? Can someone plea...

iles should be data sets. Under zOS and its predecessors data is kept in data sets hence DSN= (or DSNAME=). And for a straight copy job IEBGENER or ICEGENER should be used. I believe DFSORT will invoke ICEGENER anyway for that sort of copy but why not give a little assist to the system and specify ...

Hi,

In SORT, are SORT FIELDS=COPY and OPTION COPY same? If yes, why they have created two options?

Thanks Robert. Actually I could not make my point clear. When I used this Job: //GENER JOB... // EXEC PGM=ICEGENER //SYSPRINT DD SYSOUT=* //SYSUT1 DD DSN=CONTROL.MASTER,DISP=OLD,UNIT=3380,VOL=SER=MASTER //SYSUT2 DD DSN=CONTROL.BACKUP,DISP=OLD,UNIT=3380,VOL=SER=BACKUP //SYSIN DD DUMMY I thought SuncS...

I reread the document and it says this too: "The IEBGENER DD statements SYSUT1 (input), SYSUT2 (output), and SYSPRINT (messages) are used by DFSORT for SORTIN, SORTOUT, and SYSOUT, respectively. These DD statement names will be translated by using an extended parameter list to invoke the copy f...

read the DFSORT manuals to see what are the prerequisites ( input/output datasets attributes/specifications ) for using ICEGENER if they are NOT satisfied ICEGENER will revert to IEBGENER I have looked at this document: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ICE1CA30/9.2.16?DT=2...

This is from JESYSMSG:
What is VTRT in this? I searched for it but could not find any info.
