Mainframe, MVS and zOS Discussion

And your post said CPU time as if it is a single number. It is actually multiple numbers (TCB, SRB, zAAP, zIIP) that are combined to be called "the" CPU time for the job. So I need to calculate all these to get the CPU time or look at the CPU time from SYSOUT? ANd Where are these factors ...

System-Programmer: Is your batch job running?
Application Programmer: Yes
System-Programmer: Well you better go catch it.

No, never noticed it before.

CPU won't usually vary much for a given job -- but the system records it to much greater precision that the JES2 or JES3 output will show.  Hence you may see slight variations in CPU time but you won't generally see huge differences.  If you see more than .1 or .2 CPU second difference between jobs...

Thanks. But there are application of Java in mainframes and they can directly handle the VSAM updates as far I know but I do not know for sure. I was thiking of that kind of a way of doing it.

Hi, We are evaluating and trying to find new ways to access the VSAM file. Is it possible to update a VSAM file using php or some other language on windows? For example, if we download a VSAM file from the mainframes to a Windows Server and use a php program to edit it, will that be possible? And th...

This is a nice article on this very subject: IBM’s focus on design has its roots in a stroll down Fifth Avenue in New York that Thomas J. Watson Jr. took in the early 1950s. He stopped at an Olivetti shop where typewriters were set out on sidewalk stands for passersby to try out. The machines had sl...

Hi, I want to know what are the factors which can influence and decide on CPU time and the elapsed time taken by a Job. I have a Job which is running a simple COBOL batch program. This program has a single input file and two output file. The program read the input file and writes to output files. I ...

Hello,

Can we submit a job from cobol Program, if yes, how ? Please help.

Thanks William - we're working on the same lines. Hopefully we'll roll out this all soon.

Thanks for your comments,

Thanks Robert.

We're thinking to a file with a date in it and this will be considered as run-date. As of now when the Job is submitted is treated as run-date. Thanks again for your insight on this.

Thanks Robert, you're helpful.

I'll try to get the CA-7 Primer manual also.

Thanks Robert.

I'm exploring the options for CA-7, as you've suggested and in touch with the scheduling team.

I was just thinking if such a thing can be done by some utility program also, to get the RUNDATE?

Hi,

I have a JCL which would be invoked by the CA-7 scheduler.I'm trying to get the the RUNDATE and TIME information when CA-7 submits the Job.

Is this doable?
