Mainframe, MVS and zOS Discussion

Why not learn to use Java on the mainframe? Java has been supported on z/OS since something like 1998. The mainframe also supports most of the current "hot" development tools including Perl, Python, and Ruby on Rails.

Use the TSO SUBMIT command.

CA-7 is a job scheduler (which implies that the jobs will be executed more than one time).

1. This question comes up fairly frequently. Mainframes do not have any way to read sequential data sets backwards, so without a significant amount of effort it cannot be done. (Sequential data sets can be on magnetic tape, for example, which only can be read in one direction.) 2. The problem descri...

IBM has https://public.dhe.ibm.com/software/mig ... tility.pdf to do this.

One place it can make a difference is in handling numeric data. A PICTURE with a decimal point is an edited-numeric variable, and edited-numeric values are NOT numeric. An IF NUMERIC test will fail. Reducing memory has NEVER, as far as I know, been a consideration for the V in a PICTURE.

GnuCOBOL is a free COBOL compiler for the PC. I have used it in the past and it gets close to Enterprise COBOL so it's a good way to learn COBOL.

There are multiple types of TDQs: extrapartition point to sequential files (data sets); intrapartition are only defined and used in the CICS region (there are other types, too). So a TDQ may (or may not) be pointing to a sequential file.

Merry Christmas all!

The root cause is that there is a limit on the amount of storage that tsqueues can use and you have reached that limit. You have different options: - change the program to use less ts queue storage - live with the current situation - work with your site support group to increase tsmainlimit (which m...

It is not clear what you are asking. It sounds like you want to edit trace output in CICS.

Google is your friend. Googling "s906 abend" returns about 8,570 results and the very first one says

PH05726: S906-08 ABEND ( PROGRAM LOADED MORE THAN 64K TIMES ) IN A LONG RUNNING TASK THAT ISSUES PIF COMMANDS

The lack of answers is usually a sign that nobody on the forum can help you - possibly due to lack of knowledge of the subject. And nagging with repeated posts will NOT get you any better (or faster) answers. However, I Googled "low-values easytrieve" and found this site: https://www.ibm.c...

Are you using IGYWC for your COBOL compiles? If not, you are using a custom set up and MUST contact your site support group for assistance. There are many, many, many ways to set up COBOL compiles and each site typically does it a little differently. If you are using IGYWC, then you need to find the...

This is in the FAQ.

Transient data queues are used to access sequential data, and they're not really that rare. However, otherwise using a sequential data set in CICS is something I haven't heard of in 46+ years of working with mainframes and CICS.

From the manual: -904 UNSUCCESSFUL EXECUTION CAUSED BY AN UNAVAILABLE RESOURCE. REASON reason-code, TYPE OF RESOURCE resource-type, AND RESOURCE NAME resource-name So to resolve this, look up the reason-code to figure out what the precise issue is, and use the resource-type and resource-name to zoom...

Part of the answer is that sequential data sets aren't very compatible with CICS. Also, consider locking - writing to a sequential data set requires locking at least at the record level and more likely at the data set level to prevent corruption of data. Since you can have thousands of CICS users in...

1. How do we check if the daemon is running?

If you have permissions to do this, go into a Unix OMVS shell and enter the command If you get a line back, then the daemon is running.

This is a complicated area, but you are not correct. From the Programming Guide for version 6.4 (with emphasis added by me): DYNAM Use DYNAM to cause nonnested, separately compiled programs invoked through the CALL literal statement to be loaded for CALL, and deleted for CANCEL, dynamically at run t...

In a previous company, one of the CICS support programmers became the CIO eventually. So it does happen.
