VM Software Licensing
Let me apologize in advance for asking so many questions related to VM software licensing. I don't get a clear picture sometimes of what is a non-chargeable feature and what is. I'm preparing to install the non-chargeable DFSMS/VM feature. However, the install instructions list ISPF and the C runtime library of LE as co requisites. Does anyone know if these two components are already installed as part of the base z/VM or are chargeable features that need to be ordered separately? I'm running z/VM 5.3. Also, are there commands that will show me everything that's installed on my system? VMSES/E appears to have all the answers but not sure where in the 800+ page manual I need to reference. If this were z/OS, I could get the answers easily from SMP/e. As always, thank you for any help. Responses from the community thus far have been a huge help and greatly appreciated. Thanks...Chris (a.k.a. vm newbie)
Webshare CGI will not run using SFS
Hello list, I have been playing a bit with the Webshare package from Rick Troth. It has been succesfull so far but now I ran into a problem running CGI scripts. My webserver machine, HTTPD, is an SFS only machine. (IPL CMS PARM FILEPOOL VMSBSFS) I started with all files in the root of the HTTPD machine. This works as it should, filelists are ok and also the CGI processing is working fine. HTBIN FILELIST is available, the CGI files in there are listed as *CGI to enable execution of the script, and cgi-bin points to HTBIN so I can run CGI like /cgi-bin/CMSHELP. I can get the CMSHELP in my webbrowser. No problem there. Now I have setup the server to use the .webshare directory and moved the webfiles into .webshare and subdirectories (like .webshare.vminfo and .webshare.htbin). This way we do not have to use the FILELIST files anymore. It makes adding files and directories much easier. I can access the regular webpages (home.html, vminfo.html etc). But a CGI is not executed. I've tried several ways but so far I was not able to get the CG I to run. I guess some configuration has to be set to be able to run CGI in an SFS based structure the same way as it does in a single disk configuration. How can I get the webserver to run an CGI exec instead of sending me the file itself? TIA. Kind regards, Berry.

Chris: LE (and thus the C runtime) is an integral component of z/VM so you don't need to install anything else. ISPF is required ONLY if you want to use the storage management panels in DFSMS/VM. If you are installing DFSMS/VM for RMM or you are fine using the commands for storage management, you don't need ISPF. Jim

Hi Chris, Welcome to z/VM and this list. It is a great place to hang out! The C runtime library of LE should already be installed on your system. It is not a chargeable feature. But ISPF is. Our bill shows 5684043 ISPF Version 3 for VM/SP. It is a very old, but stable release of the product. I think the last PTF I put on was for Y2K! Ed Zell Illinois Mutual Life (309) 636-0107 .

I'm preparing to install the non-chargeable DFSMS/VM feature. However, the install instructions list ISPF and the C runtime library of LE as co requisites. Does anyone know if these two components are already installed as part of the base z/VM or are chargeable features that need to be ordered separately? I'm running z/VM 5.3. They are not, and (at least in the case of ISPF) be prepared to open your wallet Real Wide. ISPF/VM is not cheap; I don't think you need the PDF component unless you REALLY want it. But, you don't really need it unless you are going to use the panel interface. Most of the DFSMS commands also have a line-mode version. The panels are only really helpful if you are defining SMS policies (if you have DFSMShsm on another platform, you can generate the policies there and then move them over). What part of SMS do you want? If it's just the RMS piece necessary to share a tape library with z/OS, then there is a RMSONLY parm on the SMS install that bypasses the requirement for ISPF, and there is an embedded cut-down LE preinstalled that will probably suffice for your use. Also, are there commands that will show me everything that's installed on my system? VMSES/E appears to have all the answers but not sure where in the 800+ page manual I need to reference. If this were z/OS, I could get the answers easily from SMP/e. The section in the VM Service manual on the software catalog has examples. It'd be really neat if someday IBM ran a course or conference session on how to package user tools for SES - I think more of us would actually do it if we knew how. Responses from the community thus far have been a huge help and greatly appreciated. That's normal SOP for VM. We had to survive IBM and our management telling us VM was dead repeatedly, so we learned to stick together. 8-)

You can ask IBM (nicely, of course!) for a copy of Standard Packaging Rules for-Based Products (SC23-3822, the version I have here is -01). It shows how to package a VM application so that it can be installed and maintained via normal VM/SES-E procedures and tools. While it's not hard to do, it does take time and a bit of effort on a vendor's part. I suspect that the major VM vendors in the marketplace simply think that it's too much work on their part with little if any payback. I agree it would be nice to have 3rd party software packages included in the VMSES-E software inventory, and to be installable via one standard tool.

Re: Backup CMS files

If you are willing to take a Linux guest down, you can back up the full minidisks with VM:Backup or the corresponding IBM product, but you can only restore a full minidisk. If you want to do file level restores on Linux, or backups while Linux is up, you will have to use Linux based tools, such as Netbackup or Bacula or TSM. We have been struggling with this question ourselves. We licensed a CA product called Brightstore Archive Bakup (BAB) two years ago. After two years of fighting with it, we just decided to delete it. It never worked reliably. The reason to choose BAB was that it will backup to mainframe tapes (such as our STK Silos). The other Linux products want to use midrange tapes instead.

I guess some configuration has to be set to be able to run CGI in an SFS based structure the same way as it does in a single disk configuration. How can I get the webserver to run an CGI exec instead of sending me the file itself? TIA. Kind regards, Berry. -- Kris Buelens, IBM Belgium, VM customer support

Re: Backing up and restoring zVM 5.2 using IBM's DSS backup utility under zOS 1.7/1.9
Thanks, likewise our linux guests and VM itself is down. I was more curious around the cp allocations for page, spool tdisk were they preserved. Page is volatile by definition, so backing it up is kinda pointless. Ditto tdisk. Spool, you need to do with SPXTAPE if you expect it to be usable for anything other than full-pack restores. If you're taking the whole mess completely down during a backup, then yeah, you'll get good disk image data, but that seems like swatting a fly with an atom bomb. Certainly wouldn't qualify for non-disruptive operation. Spool is a moving target; at best you might get lucky but my money is that you'll probably need to do a force start and hope that nothing weird happened. That's not a guarantee I'd want to back, though. You certainly won't get a clean warm start unless the VM system is down when you do the dumps.

Re: Backing up and restoring zVM 5.2 using IBM's DSS backup utility under zOS 1.7/1.9
As long as your z/VM systems are down during the backup... no problem. The DASD allocations are housed on cylinder zero. Bot for CP-owned DASD as well as all other CP formatted DASD. That's why it is generally considered a best practice to ALLOCATE 0-0 PERM when running CPFMTXA. Other stuff is housed on cylinder zero as well, including the volser, the IPL TEXT for the SALIPL program, the dummy VTOC (that tells z/OS that there is no room at the inn , and more. The allocation bit map not marks how each cylinder is allocated, but also indicates which slots are in use (or were when the system was last running).

Re: OpenSolaris on System Z live at SHARE in Orlando
For those of you who have been following the saga of bringing OpenSolaris to System Z, I'm pleased to say that those of you coming to SHARE in Orlando will get a chance to get your hands on it live. IBM has allowed us to put a few copies of the virtual machine on the z9 in their booth, and we'll be around during the show hours to give guided tours and answer questions about it. Of course it is OpenSolaris on System z. Eventually (by the time I retire) I will get people to spell our product names right. :-) David will be at my ped on the show floor, so look in the IBM booth for the sign that says: Go Green with IBM System z Linux and z/VM on IBM System z David will be doing demos at the following times: Monday: 4:30, 5:30, 6:30 Tuesday: 4:30, 5:30, 6:30 Wednesday: 11:00, 12:00, 1:00 Jim
Re: Backing up and restoring zVM 5.2 using IBM's DSS backup utility under zOS 1.7/1.9
Brian--The appends that followed yours and preceded mine are all good advice, HOWEVER and there is always one of those. If you don't use a VM based database, you don't have to worry about that. If you are, you'd better, at least, shut it down for the backup time. The comments about the spool are right. You won't be able to do a warm start. FORCE starts are a lot more dangerous. If you didn't get one of your spool volumes backed up, you're really out of luck. There's no sense in backing up page space, altho in a DR situation, it just may be easier to restore every volume that having to read the DR doc and CPFORMAT spool volumes. Take your choice. Our DSS backups of the running system are done for DR purposes only. Yes, we won't have the open spool files and if someone was updating a mdisk at the time of the backup, you might have a messed up or incomplete backup. We do, a VMBACKUP FULL backup at about the same time the DSS backup is done so we're in pretty good shape. Once we've got the DR backup restored, and bring back up VMBACKUP, we can recover it's database from a separate backup and get that bad mdisk fixed up. Our line of reasoning is that if the data center burns down once every 20 years, and we restore that bad or dirty restores, losing the open spool files such as OPERATOR, that's good enough. Your situation may be completely different. If you have to account for every key press of an ATM, you're in a different situation.

Re: OpenSolaris on System Z live at SHARE in Orlando
Is it possible to run Solaris Zone on this ported version? How about available application for Solaris, I mean compiled binary applications, for example Sun JDK. Can't comment on other vendors plans, and I haven't tested zones yet. There's no reason why it shouldn't work, but you'd be lots better off just creating additional virtual machines via z/VM. It's a lot more efficient. We have some ideas about binary support, but that's a future problem.
reasons to NOT use EDEV
I should post this to the Linux list also, but I'll start with the VM list. On a VM system hosting Linux guests, I can think of one or two reasons why one might want to use EDEV instead of direct SAN connections. There are also some reasons why one would NOT want to. Can any of you think of reasons you would go one way or the other? Given a Linux guest on z/VM using SAN, should it go direct or go via EDEV? If direct, why? If EDEV, why? Thanks. I hope to add a slide to my SHARE pitch on this topic. -- R;

Re: reasons to NOT use EDEV
Given that performance is very nearly the same between SAN and EDEV connections, or acceptably so, then I would recommend that you go with the EDEV approach. Just have your SAN folks carve out a big chunk of SAN storage for your use, and then allocate EDEV (FBA type) disk storage for guests as needed from that large pool.

Consider what might happen if you were backing up SFS server disks while changes were being made.

Re: Webshare CGI will not run using SFS
Webshare ... wow ... that goes back a way! When using FILELISTs, you can code magical things like *CGI. For lack of a better term, let's call that a trigger filetype. But when running purely from SFS, Webshare internally creates FILELIST streams, so the only filetypes you get are a real filetypes (undoctored LISTFILE output), not a trigger filetype. Recollection is fuzzy, but I believe you can have CGIs and SFS hierarchy handled by the same HTTPD v-machine, you just cannot have CGIs living in an SFS-defined-only kind of space. For CGIs to be executed instead of served out (like plain files), they must reside on an ACCESSed disk or in an ACCESSed SFS directory and be listed in a hand-crafted FILELIST. If you can think of a way around this, you should code it and contribute it. :-) On Feb 19, 2008 6:04 AM, Berry van Sleeuwen [EMAIL PROTECTED] wrote: Hello list, I have been playing a bit with the Webshare package from Rick Troth.

HTBIN FILELIST is available, the CGI files in there are listed as *CGI to enable execution of the script, and cgi-bin points to HTBIN so I can run CGI like /cgi-bin/CMSHELP. I can get the CMSHELP in my webbrowser. No problem there.

Re: reasons to NOT use EDEV
As far as I know, EDEV -FBA emulation- uses much more CPU. At the other hand, with EDEV VM's minidisk cache becomes available, what can help Linuxes with shared minidisks.
