Question: VS FORTRAN DCSS
Good day everyone, I am trying to restore VS Fortran shared segments after a re-arrangement of SPOOL areas (by a person with an MCSE diploma, I know, ridiculous) on a VM/ESA system running on P/390. No backups of previous DCSSes are available. Have no great experiencs on doing this; last time I've been doing something with saved systems was on a VM/SP 5 system years ago. I have tried following: LINKed VSFORT 260/270 minidisks to maint machine an d run I5668806 EXEC with DCSS arg. The EXEC complains about lack of FORTRAN DEFAULTS file (which I cannot find anywhere on minidisks). The guy who us ed to support the system left the scene. Any advice will be appreciated. Alexey
Re: Question: VS FORTRAN DCSS
You may be just as well off in just forgetting about the DCSS for Fortran. If the bootstrap module or invocation exec just uses the DCSS if one is available and if there is not much or, as in our case, probably no concurrent use of Fortran, there is no savings to be gained. It sounds as if you may be better off chasing a real problem.

VMRPC placement in z/VM 5.2
When installing z/VM 5.2 I found a discrepancy between the documentation and the actually installation. The manual says that the VMRPC TXTLIB should be on TCPMAINT 592 and the tcp2prod exec place it on the MAINT 193 Where is the right place for VMRPC TXTLIB? The 5VMTCP20 CATALOG file BLD3Z BLD10Z VMRPCTXTLIB== DMSVSMAS BLD3Z BLD11Z VMRPCTXTLIB== DMSVSMAS Manual z/VMTCP/IP Programmer's Reference Version 5 Release 1.0 Chapter 5. Remote Procedure Calls subchapter Compiling, Linking, and Running an RPC Program To compile, link and run an RPC program: 1 Access the TCP/IP Client-code disk (usually TCPMAINT 592), which contains the header files for RPC and the VMRPC TXTLIB, after the disk that contains the Language Environment header files (usually the Y-disk).

Re: CMS Levels
We had a problem in the past when running an SFS SVM at a higher CMS level than CP. Specifically the VMSYS: SVM took an abend. We now insure that CP is always higher than or equal to both CMS and GCS. -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Schuh, Richard Sent: Friday, May 05, 2006 4:14 PM To: IBMVM@LISTSERV.UARK.EDU Subject: CMS Levels Tomorrow will be our next (last, we hope) attempt to move to 5.2. In the event that we should have to regress to our current system, I was wondering if it is possible and prudent to leave some of our servers at the CMS22 level. Specifically, is it necessary to fallback the SFS and NFS servers? We know that TCP/IP and all of its friends will need to revert to their former selves. Does the NFS machine have to match the level of TCP/IP? If so, does SFS have to degress to match? We are back-level with SFS and have a problem that is fixed in V5, so we really would like to leave SFS at the CMS22 level if we go back. We have been running CMS22 in most of our other service and several individual user machines (80+ users in all) for over a month with absolutely zero release-related problems.

Re: FCP Attached Tape Drives (z/VM, z/Linux) - Help Please!
Hi Paul, When issuing a SET EDEV TYPE FBA ATTR [paths] command, the value should be an unused RDEV number that will be created. The FCP RDEV number (D200) is used later in the command, following the FCP_DEV operand. Hope this helps you avoid your maintenance window.

Ack! I really can spell, but my typing is terrible when I typing into a web page. Apologies to all. Thanks Eric, I will try this in the morning. I've pretty well been up all weekend and my eyes just won't stay open. Again, apologies to the list for that horrific typing. -Paul - Original Message - From: Eric R Farman To: IBMVM@LISTSERV.UARK.EDU Sent: Monday, May 08, 2006 6:03 PM Subject: Re: FCP Attached Tape Drives (z/VM, z/Linux) - Help Please!

Re: Question: VS FORTRAN DCSS
When you generate the FORTVS2 MODULE, you are asked (or you specify via parameter, I forget) that you want one big MODULE, or a smaller MODULE and DCSS. We always used to generate and rename each, and had a stub module that would figure out which one to call at run-time. Sorry, I don't recall the DEFAULTS file. cheers, wayne
