Re: HCPPGT401I 90% of spool
That's a really good point, Rob. A thrashing system that overflows page space into spool can chew through spool at a far faster rate than even th e most egregious user / application spool abuse. (The paging subsystem has far higher bandwidth than the spool subsystem, both in terms of allocatio n and actual data movement.) Worse, paging using up spool space will almos t certainly lead to a PGT004 hard abend, whereas spool using up spool space normally just leads to spool files being closed and new writes lost. - Bill Holder z/VM Development, IBM

Eventually things will fill up when you're not looking ;-) For example because someone was going to add the new page pack later and forgot. Or because you have given out fairly large VDISKs for swap that don't get used normally (you don't want to match twice the size of all unused VDISK space in paging, I think). On most systems there should be a lot of time to react when you have the alert at 50% (and once you hit that threshold, you look back in history to see how it got there and who did it, because you may have other options than adding page space).

Re: RC = 12 FROM CSL FUNCTION DMSWRBLK; REASON: 97400
Steve, The formula for determining the USERS is not at all accurate. I once had a small filepool on a system that only had 35 userids in its directory. I found that with a value of 100 for USERS, which was higher than the formula suggested as only 16 of the users were even granted authority to access the single defined filespace, the system would rapidly grind to a halt. By upping the value for USERS to 1000, things ran smoothly.

Current versions of z/Linux don't care either. We have some that start a t even virtual addresses and some at odd virtual addresses. Older versions of Linux did have a restriction, I believe.

And even that is just an artifact of the device driver. There's nothing special about adjacent subchannels on a CTC. Your IOCP could even configure device number n and n+1 on different CTC chpids. It just doesn't matter... This even thing with OSAs and HiperSockets is the vestigal memory of the original OSA-1s that required the control path to be on an even address. I think that was lifted in the OSA-2 and was definitely gone by the time OSA-Express appeared. It ranks right up there with PORTNAMEs. They have been optional on z/VM and Linux for several years, yet I keep finding NEW configurations that have them coded and people saying they have to match, which they do, but ONLY IF YOU CODE THEM!
