Re: NETDATA QUERY rc 5 from zOS output
How is your virtual reader (00C) set? What class, hold/nohold - there are a few things you can look at.

It works better under z/VM than on the bare metal (LPAR or no LPAR). It fails miserably only in one situation, and that is where whatever you are running on it is very compute intensive. For example, Tivoli really takes a couple of IFLSs to run all by iself, and is, IMNSHO, far better situated on an xSeries blade or pSeries server.

zSeries Linux - How Many Users?
Does anyone happen to know a ballpark figure of how many companies are using zSeries Linux?? My reason for asking is I am working on trying to convince the management here that we could save tons of money by consolidating a lot of the easier workloads (ie- print servers) to zSeries Linux. One of the things I get back is no one is doing it, although I have to think there is a lot of it being used, especially with todays economy as it is. I think IBM has not done a very good job of promoting zSeries Linux, although from a marketing standpoint they undoubtedly make more money with a room full of p-boxes than one or two z-boxes running the same workload.

Re: Can RSCS start a TCPNJE link and keep listening for the remote side to start?
One thing you could do in the interrim is set up an RSCS events file to issue a START command every ten or fifteen minutes to the link. If it's already going it will just say Already Started, but if it isn't started it'll try to start it. That way it's half-way automated if they happen to recycle VM, RSCS or the other zOS side, and you don't want to get a late night call about things not going across the link because it is inactive.

However, the discussion had more to do with fetches of boundary-aligned vs. non-aligned data. There was no mention of the optimum speed for getting either a specific or an arbitrary value loaded into a register. In this day of pipelined machines This is sort of reminiscent of the good old days, programming in 7080 Autocoder. Boeing insisted that the programmers use a MOVE macro because there were 26 different ways to move data from one storage location to another. It was expected that most programmers would use either their favorite way or the first one that popped into their heads if left on their own. The macro chose the optimal way, depending on the operand definitions.

Re: Real core
I believe the 370/155 and 370/165 had core memory, and later in their lives DAT was available as an RPQ or a field upgrade on those processors. I think the 370/168 and certainly the 370/158 came with DAT and solid state memory on the base model. I recall the memory unit for the 370/165 having a model label that read 3360, that probably eliminated IBM having a 3360 model DASD!! The number I remember, but, if pressed, I wouldn't know all the specifics on what it ment was... IBM 370/168 $1,000,000 per MB. We had a 4 MB 168 which cost us a cool $6 million dollars. But I think that $6 Million was without a DAT box as the box was field upgraded later to support virtual memory. I say I don't remember all the specifics.because I wasn't in those meetings. But I was a viewer of the specifications of the replacement box (I think it was an IBM 3083...didn't that come before the IBM 3030 line?). It was, initially, a week long process with IBM detailing how you wanted your mainframe built. Do you want floating point registers? How many? Here is what they cost... So memory wasn't as simple as, I want 4 MB. It had to include cabinets and wiring and lights on the console for addressing. Not to forget, water cooling considerations and power units. The IBM would come back in a week or two, to say if you wanted xxx then we need to add in yyy and zzz and the cost is $$$. Or you can't have both aaa and bbb. It seemed to take over a month to finally spec out what you wanted to order.

Re: Rumors of the next z/VM?
I hardly think that in the 64-bit world some new CP thingie was designed to be restricted to the 31-bit world. CP was designed when all that existed was 31-bit addressing. Claiming that design is now broken 'cause it hasn't been changed fast enough to be 64-bit everywhere is just not reasonable. IMO. Richard Corak I agree wholeheartedly - if too much gets changed too quickly it could possibly cause some big-time instabilities due to the vastness of all the changes. It's better to take things one smaller step at a time and be safer than sorry. It's a lot easier to debug smaller changes anyway :-) Paul Adrian Jr.

Re: More Ancient History: source for 3420 cleaning fluid?
Try tape head cleaner for audio tape decks, that might work okay for what you're doing. David Boyes [EMAIL PROTECTED] Sent by: The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU 07/19/2006 01:48 PM Please respond to The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU To IBMVM@LISTSERV.UARK.EDU cc Subject More Ancient History: source for 3420 cleaning fluid? Does anyone still know of a source that sells 3420 cleaning fluid and supplies? In the process of working through these old tapes from Princeton, Im burning through the small supply I have of the stuff rapidly (2 pints so far), and still have a few thousand tapes to go. The amount of oxide flaking and just general destruction these tapes have is amazing gunk everywhere. Hats off to the data recovery folks Id really hate to have to do this all the time. Freeze drying, careful rereading, multiple retries sheesh. Phase of the moon for some of these volumes. Pretty scary that the circa 1970s volumes actually seem to have a higher readability index so far. David Boyes Sine Nomine Associates
Re: a really little pipe question
If they *really* want to get rid of the 'DASD cuu DETACHED' message, the following update to DMSARE will do the trick. For the most part, I like getting the message -- it verifies that the disk was detached. ./ I 0237 $ 02375000 5000 DIAGMSG2 MDC CL24' ' Detach Command Response Area ./ R 0520 0521 $ 05201990 1990 *LA R6,DIAGMSG Rx Address of CP Command LA R1,L'DIAGMSG Ry Length of CP Command ICM R1,B'1000',=X'40' Ry Turn on Response-In-Core LA R7,DIAGMSG2 Rx+1 Address of Response Buffer LA R2,L'DIAGMSG2 Ry+1 Length of Response Buffer DC X'83610008' Issue CP DETACH Request
Re: a really little pipe question
How about just setting IMSG OFF before the release... Something like this: CP SET IMSG OFF RELEASE X ( DET CP SET IMSG ON
Re: ICKSADSF
No, you can not generate a stand-alone ICKSADSF from the module. FWIW, you can generate a module from the Stand-Alone ICKSADSF file and put it on CP's CONFIG disk and execute it (just as you do CPLOAD) in case of a catastrophic condition by issuing: ICKGENSA IPL ICKSADSF Fm from the DSF maintenance userid, where IPL ICKSADSF Fm is the file name type and mode of the stand-alone DSF file. If a disk were to get messed up and you had to recover, this could come in very handy. All you do to use it is get into the HCPSAL screen and replace CPLOAD with ICKSADSF and then press PF-10. Graeme Moss [EMAIL PROTECTED] Sent by: The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU 06/21/2006 06:25 PM Please respond to The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU To IBMVM@LISTSERV.UARK.EDU cc Subject ICKSADSF Stand-Alone ICKDSF seems to only be orderable via UK15426 and UK15427 as documented in II01692. In the dim past I seem to remember generating standalone programs by punching a three-card loader then punching the module before closing the punch. The punch file was then read into a cms file and afterwards using a movefile to put it on tape. Does this work for ICKDSF and if it does where can I find instructions ? Should I even worry about keeping ICKDSF and ICKSADSF in sync ? Thanks Graeme
Re: VM users with more than 200 cylinders
If you user DIRMAP with the UNSORT option, it will create a file called DIRECT UNSORT. The First Token is the Userid, the Second Token the Virtual Address, and the Sixth Token is the number of cylinders. And, it's all neatly lined up and easy to sort !!!
Re: Performance Toolkit Tables
The PIPE VMC would work great if it could return more than 101 lines. If I could do something like PIPE VMC PTK NEXT, that could work -- although they would have to change the performance toolkit to make it work right. I have tried that, and it doesn't seem to work the same twice. Sometimes it gives the second page of userids, other times it gives the first page again.. Setting the limits does merit some thought -- that could just work! Thanks for the idea -- Paul.

(See section 'User Monitoring') These messages can then be intercepted by means of 'FC PROCESS ..' commands, and used to call your own EXECs that may do anything you want. Is this what you were looking for? Eginhard Jaeger - Original Message - From: Paul Adrian Jr [EMAIL PROTECTED] To: IBMVM@LISTSERV.UARK.EDU Sent: Friday, June 16, 2006 12:41 PM Subject: Performance Toolkit Tables I have a userid (LINUXMON) that snaps the RTM user tables once per minute and scans the linux userids. If they are over a pre-defined limit on CPU, I/O, or Paging, it sends a message to the system operator to keep an eye on that linux server - and if the message reoccurs there could be a problem with that server. With zVM 5.2 (I got RTM to work on 5.1 - it took a little work, nothing really major) it looks like RTM will not work. Is there some way to get the internal tables from the Performance Toolkit to allow me to do something similar?? Or does anyone know of something else that might work??
