Re: Wakeup and Shuttrap
I've been reading and testing: - I get WAKEUP's RC 6 too, but when calling WAKEUP again, it directly exist with RC 1. So, the SHUTTRAP signal triggers 2 WAKEUP events: COSN SMSG. Removing the CONS option doesn't do anything. - SHUTTRAP does not work like ADDRESS CMS, (so an eventual CP EXEC wouldn't matter) - Diverting the SMSG delivery method from VMCF to IUCV doesn't help either. - Using SHUTTRAP CP MSG * STOP doesn't change a thing. Bypasses: When getting RC=6, test if another SMSG event is ready too: 'WAKEUP +5 ( RDR SMSG FILE(HOBBIT TIMES *)' if rc=6 then do /* RC 6 caused by SHUTTRAP? */ saveRc=rc /* If yes, WAKEUP also has */ 'WAKEUP +0 (SMSG' /* an SMSG event stacked */ if rc=2 then rc=saveRc end Or, use the approach I ised in RxServer: I run WAKEUP with the EXT option and test for external interrupt 2401 (see subrtn Extrn_event:); SHUTTRAP can be loaded with the following: 'PIPE COMMAND NUCXDROP SHUTTRAP' 'NUCXLOAD SHUTTRAP (SYSTEM' 'SHUTTRAP' Disadavantage: when using EXT in a server that is conencted to an active SFS, WAKEUP will get many EXT 4000 interrupts (your code can ignore them, but the handling is extra overhead anyway). 2007/11/8, Thomas Kern [EMAIL PROTECTED]: The SIGNAL SHUTDOWN command was issued from another authorized user.

Re: Wakeup and Shuttrap
I'd say: test it, look at subroutine Extrn_event: and code a SAY when you get a 4000 interrupt, than you can see how often it happens in your environment. I know we can live with the number. You don't get an EXT 4000 interrupt for each SFS call, far from that. From what I tested, I see that one gets an EXT 4000 when you have an SFS dir accessed and someone issued a GRANT AUTH for you for a file in that subdirectory (the SFS server has to broadcast this to you). Maybe if you'd use Asynch CSL calls to SFS you'll get much more. 2007/11/9, Thomas Kern [EMAIL PROTECTED]: Well, at least I did not make some silly error.

CP Recording problem
A while back I had a problem in which a class g user was inadvertently given iucv abilities and started cp account recording. The directory for that user was corrected removing the IUCV statements. I then stopped recording and purged the records for the userid in question. End of story...I thought. Now I find that after each VM IPL I have to stop and purge again. Any ideas on how this could be happening and how to turn it off. The userid is seldom logged on - it has many mdisks which others link to. I checked it's profile exec and didn't see anything suspicious. Thanks for the help.

Re: Poster of computer hardware events?
If we didn't have caching controllers and we were still on the 370 I/O subsystem, would we still be concerned about RPS misses now a days? I think most disk drives have 512K of cache on them. My understanding is that you don't read/write directly to the disk anymore, but to the drive cache. And then there is the cache on the RAID adapter to consider. Since a RPS miss was that the channel path was busy with some other transfer when the block to be transferred came under the heads, true synchronous I/O, do we every do, true synchronous I/O any more?

Schuh, Richard [EMAIL PROTECTED] 11/8/2007 3:52 PM Don't forget that Marty's note mentioned the word miss in conjunction with RPS An RPS miss meant that the disk had rotated so that the next record to be read was past the heads so that there was a wait until it came back around. That was the performance issue he was talking about, and it was a big deal in those days. The maximum rotational speed of a disk was about 3600 rpm. Regards, Richard Schuh

A list of the users combined with enough EXEC DIRMAINT commands in one exec, run it and go on to something else? I recall having to do that for a different option that changed changed its default value between DIRMAINT on VM/ESA and DIRMAINT on z/VM 4.4.

I have every id that acts as an admin to the directory or as a system support person listed as authorized for every DIRMAINT command in AUTHFOR CONTROL. I don't see Kris's connection in his posting re: the 1x0CMDS file. The authorization level required for each command is included in the AUTHFOR file for each user. I tried just editing the DVHOPT entry for an id that was included in AUTHFOR and changing the record to specify NPW0. Even after restarting DIRMAINT on that test system, I had to still enter the DIRM NEEDPASS NO on that id to be able to do a DIRM FOR /userid / GET. I would like to be able to switch to the z/VM 5.3 level of DIRMAINT without having to try to explain to the userid admin people that before that can do something to the directory, they have to issue the DIRM NEEDPASS NO command from their own userid.

How I came to have it is more ironic than coincidental, given how little I know - or ever knew - about CICS. I've never seen another, although the IBM persons who gave me that one clearly had their sources. There's a CICS-L list at UGA ... I still have mine, given to me by the CICS guys on a trip to Hursley back in 1986 or 87, back when we were working on CICS/VM. :-) Alan Altmark z/VM Development IBM Endicott
