Re: What is a mainframe?

I was talking to some of our new hires the other day and none of them had heard of SNA, APPLIDs or VTAM. I prefer to think of this as the evolution of the mainframe continuing to preserve investment over time :) Still, cloud continues to try and replicate the scalability of Sysplex and TCPIP

Re: How many ways can one sentence be wrong dept

When you compress a PDS aren't you essentially de-fragging it? No, not the way the word is used on PC disks, but you are essentially consolidating fragments of free space into one big chunk of free space. Charles -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LIST

Re: How many ways can one sentence be wrong dept

PDS Compress is moving modules forward into space formerly used by updated or removed members. ADRDSSU consolidates multiple extent datasets into less extents (hopefully down to 1) and moves datasets adjacent to free space to have larger areas of free space. On Sun, Jan 12, 2020 at 11:32 AM Char

Re: How many ways can one sentence be wrong dept

Out of curiosity, its been a while since I did storage admin but it occurred to me that for the most part a lot of the work in defragging, worrying about disk geometry and other issues are really not / less of an issue with cache and SSD technologies. So, perhaps naive on my part, but it would

Re: What is a mainframe?

Matt: I totally agree. A lot of folks dont realize its not always TCPIP and the Web, there's more to z/OS then those items. Many aspects that can be developed and used. I spent 15+ yrs in the VTAM/NCP/NPSI arena including hardware and software and it provided IMHO an excellent foundation. Regards

Using OMVS cksum with z/OS datasets

Re: Using OMVS cksum with z/OS datasets

Lionel, Access to MVS Files from OMVS via "//‘your.filename.goes.here’” only works for some commands. Pre-Allocated DD’s are not available to the OMVS thread (usually). But you might try a stream … try [cat | cp] "//‘your.filename.goes.here’” | cksum I believe you can cat (copy to std

Re: Using OMVS cksum with z/OS datasets

Thanks for the idea - what I'm trying to avoid is copying (cp) the z/OS dataset to OMVS unless it has changed by comparing it's hash to the hash of the OMVS copy. Guess either way a copy will have to be done so I might as well just copy the z/OS to OMVS regardless. Lionel B. Dyck < Website: h

Re: Using OMVS cksum with z/OS datasets

Lionel, Another option would be to use a REXX that calls the CSF API’s to do this. I think this is the coding you would need: RC=COPIES('FF'x,4); RsC=COPIES('FF'x,4) ExitDataLnth=COPIES('00'x,4);ExitData=''

That was my thinking too Paul. We should be able to mask a lot of this in software and not have to do a lot of unnecessary “busy” work. Part of the challenge is to identify some behaviors that could be deprecated. We have a lot of baggage in the z/OS wagon. The defrag comment got me to th

Exactly. Let the channels emulate CKD and have maps to the actual data. NVME even got rid of the hard disk emulation layer. On Sun, Jan 12, 2020 at 6:41 PM Matt Hogstrom wrote: > > That was my thinking too Paul. We should be able to mask a lot of this in > software and not have to do a lot of
