Re: SORTWK space usage

This discussion has gone well in my meeting with the programming team. One question they asked me, about our common SORT proc: Is it acceptable to code this DFSPARM data in a single PDS member, and then let it be the default for all our SORT calls? Is there any potential problem with using thi

Re: SORTWK space usage

Yes, you are right. We are looking for a common proc (well, it is common per application team - we have 7 major teams). Once we get done going through this exercise, we will see what makes sense to update installation defaults - that is a good idea! Now, for the one big job - the COBOL program

What happened to GC26-1672 Batch Local Shared Resource(LSR) Documentation?

All, Unfortunately, I have to date myself a bit, but back in the 90's while with IBM, I implemented batch LSR on some VSAM batch jobs that significantly reduced some batch jobs run time and overall CPU usage - Hours to minutes and ~75% reduction in CPU time. I have now the need to use Batch

Re: What happened to GC26-1672 Batch Local Shared Resource(LSR) Documentation?

I rather thought the modern way was with built in things like access bias, rather than relying on a subsystem. Is there a particular reason you need BLSR? Cheers, Martin From: IBM Mainframe Discussion List on behalf of Farley, Peter <031df298a9da-dmarc-requ...@listserv.ua.edu> Date: Thurs

Re: What happened to GC26-1672 Batch Local Shared Resource(LSR) Documentation?

Martin, I understand that access bias is supposed to be the replacement for the BLSR subsystem, but I have to report that the admittedly ad-hoc local tests I have done showed me that BLSR generates far better results in reducing CPU and I/O for VSAM files than the new "access bias" tools do. A

Re: What happened to GC26-1672 Batch Local Shared Resource(LSR) Documentation?

I don’t think I’ve seen any. Anyone? I do think I heard people didn’t much like having a subsystem to do this job – after all SUBSYS= in JCL is needed. (No disrespect to those that built BLSR – twice, I believe.) Cheers, Martin From: IBM Mainframe Discussion List on behalf of Farley, Peter <

Re: SORTWK space usage

OK, the team is going to figure out what is the best set of defaults for the majority of work (80/20 rule), and then use the full DFSPARM override for those odd jobs that need to add FILSZ. I think we will leave the DYNSPC out for now, and work with the default 256 unless we need to change it.

Re: What happened to GC26-1672 Batch Local Shared Resource(LSR) Documentation?

I have never heard anyone complain abut using the SUBSYS setup to save major CPU and elapsed time. The job at hand is to use the tools we have to satisfy the business needs, not to complain about the tiny extra steps required by the tool. BLSR "Just Works", and that is good enough for me until

I activated BLSR at *current job* a few years back. I had used it very successfully at prior jobs but nobody here had heard of it. I convinced a couple of the application teams to try it on some heavy hitters and they were astonished at the difference. At the time I activated it I thought I h

And the answer is ... Although it is not so documented, apparently __TIMESTAMP__ is a C (not C++) -only feature. I am further informed that __TIMESTAMP__ is not part of the C standard, so I am out of luck. Charles On Sat, 1 Jul 2023 16:52:20 -0500, Charles Mills wrote: >I am using XLC __TIM

I did a lot of work in this area 20 years ago. If you have MXG in your shop, the ANALBLSR will suggest jobs that can benefit from Batch LSR, assuming the proper SMF types are being collected and processed by MXG. Documentation is in member ADOCBLSR. It has been 18 years since I have had access
