Hi I am a novice here but I have to admit this seems very interesting: *The IEAAPP00 member did in fact exist in MVS.* Does this mean that it is possible to apply this member to MVS TK4/5 with the

The IEAAPP00 member did in fact exist in MVS. That TK5 does not have one simply means that no appendages are used. The member, and what appendages are and how to use them, is described starting at

Thanks for your thoughts. About the only documentation that I can find about the abend in question is in a z/OS manual. It says...... An OPEN macro instruction was issued using the EXCP access method

It's been a loooong time but ISTR the 360 version of DL/1 couldn't run on MVS. The OSAM open routines built a DEB which goes into (I think) LSQA or CSA for local protected storage. In MVS there was a

I haven't had time to do anything lately with the IMS/360 DLI tape that was being discussed here a year or so ago. But I've just had a chance to have another go at it, and I've run into what's looking

The following items have been added to the Files area of the [email protected] group. * /tapemgr.tgz ( /g/H390-MVS/files/tapemgr.tgz ) *By:* Stephen Dennis

In case you are interested in seeing what the 3850 MSS looked like when it was operating, fetching the tapes from the honeycomb, I found these videos at this

This brings back cringing memories! We were part of the bleeding edge community and has 2 3850 MSS devices. In the pre HSM days, we actually were quite successful in implementing a migration/retrieval

ISTR that JES3 had some issues if the data to be transmitted via NJE/RJE was on a MSS volume that needed to be mounted. The line would hang until everything was ready causing timeouts and line

Let me clarify a few things here: User data was never read directly from or written directly to the magnetic tapes in the MSS. There was a viertualization layer where physical disk space was allocated

Bill, Sounds like your version of my mvsInstallationResources archive, whichever you use - Windows or Linux - is not the correct match for the instructions on the page. Whenever I update these

Please, download correct version of mvsInstallationResources from https://www.jaymoseley.com/hercules/installMVS/iPREREQv8.htm Andre

Hi - just a note to document a small error in the above remarkably detailed and comprehensive instructions. SMPJOB04 instruction section requests tape j90012.het - this is present but appears to be

That is certainly better than the reputation the MSS had; when the Central Bank switched to IBM, we had NCR CRAM units ("double drop!") and at some time the MSS was discussed briefly. But rumour had

My current employer recently received three new DS8A00 storage arrays, the latest, 10th generation, in IBM's DS8000 SAN storage array line. All drives in the arrays are flash core modules. --

This discussion has been interesting, a good idea that never really worked out due to implementation. --- I was unaware that IBM had discontinued all spinning platters, while I certainly myself

Back in, probably the mid 1990's, the competitive analysis team of the tape development mission in Tucson, bought one of these STK tape library silos and played around with it. They wanted to find a

Oh yes .. the MSS (or Mess as we used to call it). The JES3 interfaces were horrendous - JES3 tried to own all tapes and disks. The cobbled together MSS support was a support nightmare. At the time I

Even modern machines can be interesting. I was on-site at an implementation of a new IBM tape robot box a few years back. The box tested out fine, but intermittently shut down when we were loading

Charles, All true - with the caveat - when it worked - it was fun and amazing - HOWEVER, when it failed - there were some horrific messes - We used to laugh that this was a VERY INTELLIGENT MACHINE
