Mainframe, MVS and zOS Discussion

If you have File/Aid, you can use that to edit selected records from a larger dataset than you would otherwise be able to.

Assuming you're talking about TWS, one dataset will trigger an application with one (or more) jobs in. You cannot wait until all three datasets have been closed before the application is triggered. What you could do of course is have each of the three datasets trigger three applications that don't a...

For creating a simple UI screen with business logic, you need to create six different files in Mainframe(COBOL). Whereas in Java, you can create it with two files only. So, I think Java is better than Mainframes. And, let me assure you, Java is the future. It's here to stay for long. Surely that ju...

Have a look at the SMF type 61 records.

Assuming that all of the parameters for each volume are the same apart from the device address and the volser, you could perhaps write a utility in a language of your choice (Rexx would be simple enough) to generate the JCL for a batch job which then could be submitted. It would be simple enough to ...

We have used the ¬RUN test successfully in this scenario, in conjunction with your existing IF test. If the first step hasn't run due to the restart, the condition will still be true and your subsequent steps can run. Alternatively, what scheduler are you using? TWS can be configured to retain step ...

Have you tried the NSCR operand?

Although of course if you're on z/OS v2.1 you can use the GDGORDER parameter so that all generations are NOT processed in reverse order.
