SYSIPL macro in DMKSYS

 

Hello,

I've been reading through the various VM Planning guides looking for information on the SYSIPL macro, but I can't find any, even in the R6 PLC17 or VM/SP R3 manuals.? Where can I find documentation on this macro?? I should remember, but don't, where the MACLIB is for the DMKSYS macros.

Thank you in advance for your help,

Bertram Moshier

SYSIPL seems to be an addition to VM/370 by the Hercules community. The file SYSIPL MACRO is located on minidisk 094 of MAINT. I am sure some people in this group can tell you more about it.

Hello, and thank you for your reply.

What?do people think of having VM support going down the list concerning IPL startup? By this, I mean that if WARM fails, failover to CKPT, etc., if allowed by the SYSIPL macro.

Examples of these are:

SYSIPL? WARM and CKPT. This would mean that if WARM fails, then go to CKPT, and if it fails, then present the prompt to the operator. If SYSIPL?was WARM, Force the system would not do a?COLD start leaving it to the operator.

You can see another discussion of the sequence here: /g/h390-vm/message/4517

This is kind of late in the game for us, but provides some background on the sequencing and why. See page 12.



When I was a sysprog for a university system, I wrote a program to backup spool files, so if we couldn't recover from WARM/CKPT, we would choose COLD and reload those we were sure of from tape, rather than guessing what we might recover from a FORCE.

Hello Mark,

When I woked for Owens Corning Fiberglas Research Center as it lead systems programmer, I wrote a program to backup the spool space every hour.? We didn't use it often, but it saved some people who purged one or more files.
