Lee Stewart wrote: Is there a way to tell from a CP command if a guest is running in 31 bit or 64 bit mode? Thanks Lee Not directly, but you could issue the DISPLAY PSW command on behalf of the target user (using the FOR command in z/VM 5.3, or via SCIF for earlier releases) and interpret the result, which will be like one of the following: Guest in 31-bit mode: for operator cmd d p OPERATOR : PSW = 030E 8105B570 OPERATOR : HCPFOR069I Command Complete. CP return code = . Guest in 64-bit mode, PSWTRANS OFF: for raylx2 cmd d p RAYLX2 : HCPCDP6150E The option PSW has been specified but is not valid in z/Architecture mode. To enable the use of this option issue the appropriate SET PSWTRANS command or use the PSWG option. RAYLX2 : HCPFOR069I Command Complete. CP return code = 6150. Guest in 64-bit mode, PSWTRANS ALL|DISPLAY|STORE: for raylx2 cmd d p RAYLX2 : PSW = NON TRANSLATABLE PSWG = 07060001 8000 00107E2E RAYLX2 : HCPFOR069I Command Complete. CP return code = . And yes, it would be very easy (code-wise) to provide a QUERY command option to give this information, or you might try the following piece of REXX from a suitably-privileged userid (this, of course, is subject to VMDMMODE remaining at the same offset in the VMDBK - which it has for at least the last four releases): --- /* QMODE: determine whether a guest is in 64-bit mode */ Parse UPPER Arg uid If (uid='*') Then uid = userid() Numeric Digits 20 'PIPE CP LOCATE' uid '| spec w3 1 | var vmdbk' If (rc0) Then Do Say 'Error' rc 'from CP LOCATE' uid'' Exit rc End vmdmmode = d2x(x2d(vmdbk)+x2d(4c4)) 'PIPE CP DISPLAY HS' || vmdmmode || '.1 | spec w2 1 | var mode' If (rc0) Then Do Say 'Error' rc 'from CP DISPLAY HS' || vmdmmode || '.1' Exit rc End If bitand(x2c(mode),'40'x)='40'x Then Say uid 'is in 64-bit mode' Else Say uid 'is not in 64-bit mode' --- Or one could write a CP QUERY command extension - isn't that possible? I'll take a look and maybe post something later. Ray
Re: Guest in 31 or 64 bit?
If you have TRACK installed, that'll answer the question on an ad-hoc basis without any further programming effort on your part. Otherwise, if it were me and I were looking for a reliable, programmable interface I reckon I'd be starting to think about writing an extension to QUERY ...

Re: Guest in 31 or 64 bit?
Do you want to query that on the guest itself or from some other virtual machine? On the guest itself: #CP D P (it will bitch if it's running in 64-bit mode where you need to use #CP D PG - unless the guest has the PSWTRANS set to DISPLAY). If not, you'll be checking VMDBK stuff like Perfkit etc. do. Is there a way to tell from a CP command if a guest is running in 31 bit or 64 bit mode? Thanks Lee
Re: Guest in 31 or 64 bit?
The 2G test is never valid. That was a facetious suggestion. It is possible to run a 32-bit system in 2G and just not use the storage above the 2G limit, or as the earlier releases of VM did, use it to support guests. And it is possible to run a 64-bit system in 2G or less. If it is MVS instead of z/OS, that might be a valid test. Was anything actually named MVSx ever 64-bit? Not having to support an MVS guest since 1985, I do not know. Even then, it is no help for those who are supporting guests other than of the MVS - z/OS variety. You may have a SHARE requirement. I do not imagine that the programming will be rocket surgery. All of the red tape and process will likely be worse by orders of magnitude.

Re: Guest in 31 or 64 bit?
(Slightly off topic) I had a user request additional memory because their image was slow, and I tried to explain that it wouldn't help because they weren't CPU bound. They insisted and I finally gave in and increased the image from 2gig to 3gig. I waited a couple of days, and then asked if it had helped. The answer was a resounding Yes!... As they calmed down again, I said Well, you know... Your SuSE 8 31-bit image can only address 2gig, so that additional gig isn't actually being used for anything at all They tend to listen now when I tell them something won't help. -- .~.Robert P.

And GCS because it runs DAT off, too. -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Alan Ackerman Sent: Saturday, 11 August 2007 3:07 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Guest in 31 or 64 bit?
