Re: Linux Monitoring
Frequently this problem is caused by memory problems within linux. From VNC, launch top and watch it carefully over an extended period. if you see memory used creeping up or swap space used creeping up steadily, you might have an application with a memory leak.

All 4 guests were cloned from the same base install. The problem we have is that occasionally, Linux will stop functioning. Our connection is via VNC. I haven't been able to establish a pattern as to what is causing this. The symptoms are as follows: Linux could be up for hours or days running fine. Working on anything from YaST to web browsing to accessing a SMB share, upon clicking something, the VNC session will hang and then disconnect. We've tried logging on to the guest under VM, but even VM doesn't allow us to do anything. We end up forcing the guest off using MAINT. Then, we can reboot the image fine and it could run fine for hours or weeks. I've checked our HMC for CPU activity on the IFL, but it is 5% utilized so I don't think something is looping. If anyone has experienced this, I'd be curious to hear how your resolved it. Or, if anyone knows of a way to log what is happening, that might help as well.

Re: Backup clients
We are using TSM and are moderately happy with it. The TSM server runs on z/OS and was originally purchased to back up zOS USS. The client runs on the linux servers. It's moderately fast to our zOS virtual tapes and is relatively simple to use. We may add the Oracle table backup piece. Byzantine pricing model is right. We had a meeting with ourselves, our buyers, our IBM SE, the local IBM reps, the local Tivoli reps, the regional Tivoli sales manager, and a national Vice President of Tivoli on the phone, all at the same time. We spent four hours trying to figure out what the price was and no one could figure out how to price it for a zOS server, zVM with two IFLs and about fifty linux guests and several hundred linux users. After four hours or so, one of the Tivoli reps just said, Let's just guess that this is how it works and write the contract this way. So, even Tivoli can't figure out how to price their own stuff.

Re: Oracle and Linux under z/VM
We have almost exactly the same setup. Same linux, same oracle, same vm, and same processor box with the same number of IFLs. However, we have about twice the amount of real storage you have, and we're seeing the same problem. The problem is, simply, memory. Oracle uses a lot of it, especially if you have Java or Tomcat front-ends to Oracle. Several things you can try: Try reducing the amount of virtual storage on the server to the point where it will just run reliably. Set up linux swap in V-disk. Give it lots of swap space. We use 2:1 swap to virtual. Set up multiple (dedicated!) volumes of paging space on your VM system, The total paging rate divided by the number of dedicated paging volumes should not exceed 100, nor should your paging volumes get more than about 40% full. VM paging should be to the fastest DASD you have. Set up your oracle database across lots of small volumes as opposed to a few large volumes and, using LVM, stripe it. If your user is using a lot of Java-like processes, see if he can rewrite them into C and compile them. If these don't solve your problem, I'm afraid the only recourse is more real memory in the processor box. We just ordered another 8GB for ours, just for this purpose.

The results of our performance tests are bad (in words of our DBA, because my problem is that I have no knowledge of Oracle, so I only know what my DBA tells me). What I can observe from Performance Toolkit is that we have a high rate of pages moving from central to expanded, and from expanded to central, causing a high CPU use. At this moment, I'm aplying fixes UM31411 and UM31485 because they are commended for this kind of problems. Any help would be welcome, because I have tried everything, and I don't know what could be the problem. http://webmail.wanadoo.es.

Re: zVM SLES 9 instance becomes inoperative
Sounds like one of your applications has a memory leak. Run top and watch the memory statistics for the system as a whole. If it appears to be increasing steadily, watch the memory of the processes running to see which one is using memory and not releasing it. You didn't say how long it will run before it dies. If a few hours, you can catch this easily with top. If several weeks, you have to monitor it periodically over days and days. Some people are like Slinkies...

Re: Mainframe REXX EXEC to logon to zVM Linux instance and issue commands
The easiest way to do this is if you are running a release of zVM late enough to use the CP SIGNAL command. I don't remember when exactly this command was added to zVM, but I think it was zVM 4.3. The following is for SuSE Linux and will work on SLES8 or SLES9, but not SLES7. It wil probably work on RHEL3 and RHEL4, but I haven't tested it. Go into Linux and add the following lines to /etc/inittab: # what to do when CTRL-ALT-DEL is pressed ca::ctrlaltdel:/sbin/shutdown -h -t 4 now Then look at /etc/zipl.conf and be sure the line with root=/dev/dasda1 (or whatever your root disk is) contains vmpoff=LOGOFF Run zipl, shut down and reboot your linux image to make all of this active. Now when you want to shut down the linux image, say LNX6, from VM, issue the command CP SIGNAL SHUTDOWN USER LNX6 WITHIN 60 (if this is running Oracle, you may want to make the 60 be 300) Then set a loop to monitor the command CP QUERY LNX6 And look for a return code of 45, which lets you know the image is down. Then do what you need to do to back it up, and restart it with CP XAUTOLOG LNX6 (The linux image may need an XAUTOLOG entry in its directory to allow this) The Church is near, but the road is icy.

Then through the scheduling mainframe package, a mainframe job could be run to do an FDR backup of the DASD assigned to that instance. When the job successfully completes it could trigger a subsequent mainframe job to issue a command to bring the z/VM instance back up. I was thinking I could use a rexx exec to make this happen, but I am not quite sure how. Is there an easier way to accomplish this task? Well, the *easy* way is to license FDR's Linux backup solution (it works well, and since it's running inside the Linux guest, it handles the caching problem neatly). But, we're here, and easy solutions aren't any fun... This actually would be a good use of our SYSVINIT package -- it's got all the PROP automation for controlling guests already done; you'd just need to set up the NJE connection between z/OS and VM. The price is right, anyway. In that case, your command to send from z/OS might look like this: XMIT (MSG) VMSYS AUTOLOG1 SERVICE linux STOP(shuts down the Linux guest gracefully) Wait a bit, or wait for the service stopped message. Do your backup XMIT (MSG) VMSYS AUTOLOG1 SERVICE linux START(bring the Linux guest back up) If you made a minor modification to the SERVICE exec in SYSVINIT, you could send a file back that could be used to trigger the backup job via a ETT trigger in TWS or CA-7. You'd need RSCS on the VM system, and a CTC connection to z/OS to make this work, but that's actually a good thing; once this is available, then you can do a lot more with controlling the Linux environment from z/OS. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

No-password public-key access is a little more complex. If not, try erasing all the keys in /etc/ssh that were generated at first boot and then rebooting to regenerate all the keys.

Re: Hundreds or Thousands?
As Bill Bitner would say, It Depends. With Linux it depends even more... It depends on the nature of your hardware and the nature of your computing load. A small CPU with a small amount of memory and slow disk drives will have trouble. The oft-quoted experiment with thousands of servers ran some 40,000 identical Linux images with apache webservers all serving the exact same page with almost none of them actually being accessed. One the other hand, I am informed that Deutche Telekom and Bank of Venezuela do run over a thousand active linux servers on the mainframe with no problems. We ran 42 Linux servers, mostly Apache and Samba, on a 2-IFL z800 system with 8GB of memory and very old (7 years old), slow DASD with no problems other than the occasional performance problem with Java or Tomcat. We had capacity to spare and figured we could handle 300-500 servers. Then we added 8 Oracle 10G servers at around 1GB virtual each and things started to slow down considerably, even moving to 11GB of memory. We're running about 50GB of virtual working sets in 8Gb of main memory and 3GB of expanded. Basically, Java, Tomcat, JBoss, Websphere and the like use lots of CPU cycles. they can max out your CPU in no time. Oracle and multiple Java processes (e.g. Websphere) and the like use lots of memory. VM paging and linux swapping to slow DASD just makes it worse. You can (and we do) move Linux swapping to V-disk and take advantage of expanded storage, which essentially moves Linux swapping to VM paging, but if your DASD is slow, you will see slowdowns and page waits.

A question about Linux on z/VM and scalability. Early tests of Linux on 390 (Test Plan Charlie and Omega) demonstrated that thousands/tens of thousands of virtual Linux servers could physically be supported by z/VM (and I note with respect that Sine Nomine has a presence in this forum). These days IBM steps up to the plate in public for 'hundreds' of virtual servers (ibm.com), and Charlie/Omega aren't referred to as frequently. There is a big gap between hundreds and thousands. My question ... is zVM (with up to 16 engines) really capable of supporting thousands/ tens of thousands of servers in the real world, and IBM just being coy? Or is it really hundreds? If it is in the thousands, is this theoretical, or are there really customers using it at this level? For the purposes of this question, let us assume a 'server' is used by a small business of 10-20 employees with several hundreds of customers, supporting web site services and email (in a penguin colony with non-uniform resource demands). Vague, but hopefully a pointer to something useful. I recognise that this question is dependent on a wide range of variables. These would include the fact that the actual workloads encountered will matter a great deal. Possibly there are many opinions about this, and no one correct answer, but I am very interested in hearing perspectives from those with first hand experience. Apologies in advance for asking such an open ended question, or if this question has been tackled in depth previously. I could find no references in the FAQ or recent postings. If there is a more useful way of defining a standard small business workload that you are aware of, please comment using that as a base. Before you criticise my lack of precision on workload, I hope you can comment on the basic question (admittedly posed from a perspective that is less technically informed on z/VM than most participants in this forum). Personal disclosure: I am a former IBMer, from the business consulting group rather than hardware/zSeries. My interest is in the potential commercial application of Linux on zSeries, beyond server consolidation.

Re: SLES 9 SP 1 - Tomcat IBM Java - failure.
I submitted a ticket to SuSE/Novell on the Java/Tomcat bug. I got a reply (below) that this appears to be a problem within IBM Java for zLinux itself and i should report it to IBM. Anyone know how or where? Do I just go through IBMLink or is there somewhere else? Hi Gordon, thank you very much for the crash report. I am getting reports from one of my systems administrators that, within SLES9-SP1 for zSeries (64-bit) running under z/VM 5.1 on an IBM z800 machine, the use of java causes Tomcat to crash or hang. What I can see from the crash analysis is: SIGABRT received in gsignal at 0x20a2a9c in /lib64/tls/libc.so.6. Processing terminated. Don't get confused by the notice that it seemed to have happend in libc.so.6, aparently gsignal() with SIGABRT as a parameter was called with the default interrupt handler in place. As gsignal() has been marked obsolete for ages under Linux, the application or library using it is very unlikely some of those we have access to the source code... SIGABRT usually gets used to exit a program cleanly after a caught segmentation fault (alternatively, some programs and toolkits such as Motif use SIGBUS for this purpose) Unfortunately, I don't see which one of the Java threads has called this function, but all threads where doing something in libhpi.so. Thus it is save to assume that libhpi were calling it. libhpi belongs to Java2: /usr/lib/IBMJava2-1.4.2/jre/bin/libhpi.so Thus it is safe to assume that this is an IBM Java bug, you might wish to ask IBM for further analysis.

Re: DASD shared between SLES9s.(running on different z/VMs)
In certain circumstances, sharing a limited amount of dasd read-write among LPARs is possible using hardware reserve/release. We do this with our shared tape catalog in VM:Tape (which is on its own real 3390 with its own controller separate from our regular DASD.) However, it is NOT useful if there is more than just a little I/O to the volume. It will lock up the volume(s) in question faster than anything if there is lots of I/O. It also opens up a can of worms and I do not recommend it unless you really really know what you're doing. We had lots of help from IBM, STK and Systems Center (before it was Sterling, before it was CA) in setting it up for VM:Tape and our STK tape silos. I'm not going to stick my neck out and advise you on how to do it in an e-mail without knowing your system or what you're trying to accomplish. If you're really interested, seek help from your IBM SE. A statesman is a dead politician.

Our client uses SAMBA for file and print on an NT4 domain and we are working on migration to Active Directory on Windows 2003. To simplify the migration of users to the new domain, the plan is to create a new global group and nest the existing global group within.Also we have received conflicting advice as to whether AD needs to run in native or mixed mode in work with SAMBA. So I guess LDAP is out of the question. Too bad. 1. Can SAMBA handle nested global groups? I don't believe so - UNIX/Linux groups cannot contain groups. I recall someone flattened nested groups somehow, but this was a migration strategy, not a coexistence one. 2. Are there reference sites and/or other IBM experience with SAMBA and Active Directory? I know there are a few shops out there doing this. I recall TCS presented on Samba at SHARE about a year ago. Anyone? 3. What mode should Active Directory run in in order to interface with SAMBA? I believe with Samba 2, AD must be in mixed mode. With Samba 3, AD can be running in native mode (but that precludes 9x/ME clients).

Re: zLinux 31 to 64 bit
So, my assumption, based on real hardware on other platforms, that if you install Sles9 on a 64 bit VM user, it installs Sles9 as 64 bit. If you have a 31 bit user, it installs as 31 bit. But I haven't seen any documentation on how a decision is made during Sles9 installation. Actually, If you buy SLES9, you have to specify if you want 31-bit or 64-bit. If you buy the 64-bit, you get the 31-bit version at no cost. The product comes on a set of CD's. Six CD's for 31-bit and 6 CD's for 64-bit. Pick the set of CD's you want to use.

More CPU in SLES9
Hi, List: I'm seeing what appears to be an unusual situation. SLES9 (64-bit) appears to use about 3 times as much CPU time when idle as SLES8 (31-bit) and I can't see why. If this is systemic, it's going to make mainframe linux a harder sell. With SLES8 we're selling mainframe linux (partly) on the basis of the fact that it costs about a third of what a Windows server costs. That advantage is wiped out in SLES9x. We're going to 64-bit because we have some Oracle servers that need to get really big. We'd rather not maintain two systems, 31-bit and 64-bit. That drives our costs up, too. cat /proc/sys/kernel/hz_timer shows 0 top shows 48 processes in use, only 1 active (top itself). snmpd pops up every so often, but it does in SLES8 as well. All other processes show 0 cpu. Nothing unusual there. I noted the paging rate of the SLES9 server was a bit high. top showed swap (to v-disk) in use, so I bumped the virtual memory to 128M from 80M so it doesn't have anything in swap at all. Didn't help. SLES8 generally runs 64M. I turned off snmpd and the firewall. Didn't help. Is it just that SLES9 64-bit uses more cpu than SLES8 31-bit? 3 times as much? Or am I missing something? .

I'm in the process of building cpint-2.3.0 and making it GA (it fixes a
problem with 32-bit programs on a 64-bit system). The build process requires
that you use the kernel build method. The Makefile should now look like:
cpint_mod-objs := cpint.o cmdmain.o idmain.o monmain.o actmain.o
obj-m := cpint_mod.o
prefix =
bindir = /usr/sbin
COMMAND = hcp mongen monstat actgen diag0

install -c -m 750 hcp ${prefix}${bindir}
clean:
rm -rf *.o *~ core mongen monstat actgen hcp diag0 *.ko *.cmd
.tmp_versions
The build process is:
1. For the device driver -
make -C /lib/modules/`uname -r`/build M=`pwd` SUBDIRS=`pwd` modules
You need to have the kernel source installed and at last a make *config
performed.
This will generate cpint_mod.ko which can be installed via:
make -C /lib/modules/`uname -r`/build M=`pwd` SUBDIRS=`pwd` modules_install
Issue -
depmod -a
Then modprobe cpint_mod to load it. In SLES9 SUSE have decided that major
no 107 is
used for cpint so you could put an entry into /etc/modules.conf to get the
driver
loaded automatically (i.e. sans cpint_load).
2. For the utilities (hcp etc.)
make tools
The 2.3 package should be available shortly. In addition to the ioctl fix it
contains a
fix for the diag0 driver on 64-bit systems.

Is the diag dasd module in SLES9?
I'm in the process of installing the 64-bit version of SLES9. If I do a lsmod, I don't see the dasd_diag module to be able to use diag minidisks. doing a modprobe on dasd_diag_mod gives me a fatal error: not found. doing a find for dasd_diag* shows me the .c and .h files for it, but I can't find a .ko file to load. Is the diag module included with 64-bit sles9 and I'm just using the wrong name? Do I have to compile it myself? If so, does anyone have any instructions on doing so?

Re: Thanks for your concern WAS: Red Hat Enterprise Linux and NSS
Betsie, et. al., I'm doing much better. At SHARE, I felt like something the cat did on the rug. (actually, I would have had to improve significantly to feel that good...) I won't go into all my symptoms to preserve the sensibilities of those on the list, but let's just say it was really ugly. I went to the emergency room in Anaheim and a committee of five residents overreacted to my symptoms and told me to IMMEDIATELY go home and consult my specialist, since my condition is a very rare one and none of them had ever treated it. With the help of Alaska Airlines, I was in the doctor's office in Seattle at noon the next day, and she immediately put me in the hospital. After a battery of tests, it was determined that I was NOT having a major emergency of my long-standing condition, just a li'l ol' kidney infection. Five days of rest at home and massive antibiotics and I'm back at work. A lot of people on this list and elsewhere have been so kind as to inquire about me. That's why I'm responding to the list instead of back to you personally. I want to thank you all for your concern. So one elephant says to another, You'll never believe what happened last night.

Re: Putty users
I could do that, but I'd have to pay for it out of my own pocket. The company won't.

CTCMPC Driver
We are currently running SuSE SLES8-SP3 (31-bit) on our z800 mainframe under z/VM 5.1. We have a need to run the IBM Communications Server to replace soon-to-be-unsupported communication controllers and CIP routers. This is an ideal solution for us and a perfect use of Linux. The IBM Manual GC31-6769-00 IBM Communications Server for Linux on zSeries Quick Beginnings on zSeries, page 18, says CS Linux requires the zSeries Multipath Channel device driver to communicate with VTAM via CTC. The IBM manual LNUX-1313-04 Device Drivers and Installation Commands October 7, 2004 Linux kernel 2.4, June 2003 stream, in chapter 12 describes the installation and use of the CTCMPC device driver. It says that all that is needed is to modprobe ctcmpc I cannot find the ctcmpc.o module anywhere on my SLES8-SP3 (31-bit) system. Nor can I find it on any of the installation or service rpms I have downloaded from the SuSE site. Can anyone tell me where it might be? I can find the patches for the 2.6.5 kernel on the IBM Developer site, but we're still waiting on our purchasing department to get through the paperwork of getting it. (It's been three months.) I can't find the patches for the 2.4.21 kernel, and really don't want to go through all the work of learning how to apply kernel patches and recompiling the kernel. Does it come with SLES9 64-bit?

Re: Max Mount Count
This is just a note that the filesystem has reached the maximum number of mounts allowed before it does a complete recheck of the filesystem for errors and internal consistency. You will note that check forced means it's doing the check. You don't have any problems, this is just an informative message, and the check is a good thing to do periodically. It slows down your reboot, though. If you want to change the number of mounts before a check is forced, run tune2fs if this is ext2 or ext3. I don't recall what the command is for reiserfs or any other file system. Why are you still running the Marist distribution? That thing is almost five years old. There are many other distributions out there that are later releases with a lot of newer features you -WILL- want to use, especially the SIGNAL SHUTDOWN feature and use of Guest Lans or VSWITCH. Marist is, if I recall, the 2.2.16 kernel. You'll want the 2.4.19 kernel or later if you can get it. The current kernel is 2.6.x. Check out linuxvm.org.

Setting up VMNFS
This is cross-posted to both the VM-ESA list and the Linux-390 list. Sorry for the duplications. I have a number of apache webservers on several Linux servers that need to use various pieces of data that is also in use by a number of VM webservers using VM:Webgateway. This data is updated every few months. Rather than go around and update all the various locations, it would be most convenient if I could update it in one location on VM and just have all the other systems be able to use it. It seems that NFS would be the best solution. I looked at cmsfs, but I also need the occasional read-write capability. So I'm trying to set up VMNFS for the first time. It's considerably different than NFS on Linux. I'm having all kinds of problems with permission denied. I'll want to serve out both minidisks and SFS data. I'd like to use VM:Secure as the ESM, but I can live with just using the CP directory entries. Could someone who has VMNFS working and accessible from Linux send me: 1. A copy of their VMNFS CONFIG file 2. A copy of the relevant parts of the DCTPARMS file for VMNFS 3. The syntax of the mount command you use from linux. What do you do about hard-coding the passwords in the mount command? 4. Anything else you think I'm missing? So one elephant says to another, You'll never believe what happened last night.

Re: Veritas NetBackup
I can confirm it. At SHARE in Washington DC August last year I talked with the Veritas people and they said a client would be out in October of the same year. Several months ago there was a note that appeared on this list (which I no longer have a copy of, but should be in the Archives) that said Veritas didn't think there was enough of a market for its product on Mainframe Linux at this time and would revisit the decision in 2006 or 2007. Needless to say, this caused us a lot of grief. We wanted a common backup system across all our Unix-type operatng systems for commonality of processes and training. We are currently using Tivoli TSM for backups. The VM server for TSM is stuck on a backlevel release and probably will never be upgraded. The Linux/390 TSM server is up-to-date but does not talk to ESCON-attached tape drives. We are using the TSM server at the current level on z/OS and using the Linux/390 client to back up to it. It puts out a lot of data over the network (DON'T do compression! CPU cycles are more expensive than network bandwidth.) but it's easy enough to use and even has a web interface. The licensing for this setup is very confusing, both to us and to our local Tivoli rep. We mostly did it this way because we already had the server on z/OS and adding the Linux clients was very inexpensive. For a VM and Linux -only solution, we've heard really good things about CA's Brightstor product, although the cost is more expensive (for us) than TSM. However, some people don't like to deal with CA. Amanda and Upstream are two other possibilities. Amanda means you have to grow-your-own tape interface and catalog. I know nothing about Upstream.

Re: Securing VM using LDAP?
rant You really need to educate your management that just because you have RACF on z/OS doesn't mean you have it for VM. If you have two cars, an oldsmobile and a toyota, and the toyota has a steering wheel, that doesn't mean the oldsmobile can use it at the same time. RACF for VM and RACF for z/OS are two different products and require two different licenses. Let me recommend VM:Secure in place of RACF. It's a much better product, easier to use and far more capable. And let your management know that running without an ESM is just an invitation to hackers, both internal and external. VM's built-in security is pretty good, but someone knowlegeable in VM systems can break it. (True story: About 18 years ago I got a job as SP with a small company that had a fairly new VM system. First day, I said I'd need a userid. The boss said the guy that gives userids was out that day. Six minutes later, I went back to him, having logged on as MAINT, and told him his security sucked. They didn't have an ESM. Six minutes to log on to maint without knowing a thing about the system beforehand. Old-timers will know exactly how I did it.) Finally, what company do you work for? So that I'll know never to apply there. I already have enough problems with clueless management where I work now. /rant All that said, the answer to your question, is it possible to authenticate VM against LDAP on z/OS? The answer is, in principle, yes. The real, practical, answer is no. VM does not interface with LDAP directly. There are no products on the market or available for download, to the best of my knowledge with 21 years of experience with VM, that will allow you to do this. So what you are left with is writing your own. IBM supplies the ESM stubs (HCPRPI, HCPRPW and the like) that allow this and provides documentation (somewhere) about how to write ESM interfaces. You could, in principle, if you are a REALLY good assembler programmer (and writing assembler code for CP is two orders of magnitude harder than writing application code in assembler) you could write an interface to have VM contact a remote LDAP for authentication, possibly over CTC's or hypersockets. You'd have to have some kind of default authentication in there in case communications were down or z/OS was down. This is not a job I'd want to try. Just writing three CP exits a few years ago took me four months full time and I crashed the second-level system more than 400 times and the first-level system (when I put the exits on it) about half a dozen times. I learned more about CP internals and how to use VMDUMPTL than I ever wanted to know. Do you have the time to take on this project?

Re: Shared /usr
This is one possible architecture. Whether it's recommended or not depends on why you want to do it. The advantages are 1) saving disk space. Depending on how expensive dasd is in your organization, this can be considerable. 2) Allowing minidisk cacheing to take place, reducing the number of physical I/O's and speeding up response. 3) keeping your users from installing programs or making modifications on their own and then calling you at three in the morning when their server goes down. then you find out after two hours of work that the problem is some modification they made. 4) Creating a standard version of Linux that is easily deployable. The disadvantages are: 1) Service is much more difficult. You have to install updates on a test server, then compare before and after with tripwire to see what files were updated on /usr and which were not. You have to route the non-/usr files around then swap /usr disks and reboot. You end up having almost as many /usr disks with different versions on them than you would have if everybody just had their own disk. I've got 38 servers and 6 different shared /usr disks, not to mention 4 or 5 servers with non-shared /usr. 2) you have altercations with users who want to write to the /usr disk. Usually you can get around it by loop-mounting a subdirectory in /home over a /usr subdirectory. Installing WebSphere with a read-only /usr is virtually impossible, as are other program products. I'd say if all of your linux servers are essentially identical, shared /usr makes a lot of sense. If they are all configured differently, question it. We've been using shared /usr for about three years. We are considering going to individual read-write /usr areas with SLES9, just for the ease in maintenance. Disk is cheap here. We bill our customers only $6.14 per gigabyte per month for 3390 dasd storage. A full-pack 3390-3 for /usr is about 80% full and is about 2.2GB.

Re: mp2003
Basically, you can do one or the other. What you're asking is I have a ford. Can I install a chevy on it? Both Marist and Debian are versions of Linux, as are Suse and RedHat and Slacware. Choose one of the five. Frankly, the Marist version is quite old now and rather out-of-date, still running the 2.2.16 kernel. You at least want the 2.4.x kernel because it has all kinds of goodies in it to make things easier. If you want free, go with Debian. If you want support, go with SuSE or Red Hat. The Slacware version is quite new, and if you're new to Linux on the mainframe you might want something that's been around a while and has a long-established support group for the mainframe. It is actually conceivable to install Debian on Marist, but it would take a lot more knowlege than I have, or most of the people on this list have, to do it.

You follow the prompts. If you're running on an MP2k3, you could also get Matt Zimmerman's preconfigured DASD image (50 MB) from: http://people.debian.org/~mdz/hercules/Debian-3.0r1.3390 This is intended for Hercules, but I think it should work as an emulated DASD volume on a Multiprise. It's slightly out of date so you'd want to do an update to 3.0r2, but you can easily do that over the network. On the other hand, if you plan on installing many images under VM, Sine Nomine makes and sells a CD set of the Debian 3.0r2 release, which lets you easily set up an installation server, so your guests don't have to use external network resources except to fetch security updates. (We are also working closely with the debian-installer team and hope to have a 3.1 Sarge distro, similarly packaged (although probably on DVD, not CD) soon after the official release.) The CD set is $150 (whereas the first two options are $0, but more time-consuming if you're planning on multiple Debian images), and you can also buy real live commercial production support from us if you want.

Re: Linux under VM and Cloning
How much DASD does this really save you? Is it worth the time and effort it takes to set this up A lot of people do it this way. I gave a paper on it at SHARE. You can see a copy at http://linuxvm.org/present/SHARE101/S9343GWa.pdf It covers a wide gamut of the problems of managing multiple Linux servers running under VM. Lately, however, we've been beginning to have second thoughts. When we started the scheme detailed in the presentation, we thought a whole 3390-3 was a lot of dasd and were trying to save as much as possible. Now that we're running about 40 servers, maintenance is becoming a real pain in the patootie. Getting our users to allow us to take down their server so we can change /usr disks is really hard. More and more our users are wanting full 7X24 availability. Our current offering is 1500 cylinders for /, /opt, /bin, /var, etc 3338 cylinders for /usr, read-only shared. swap in v-disk A separate disk with much as they need for /home A read-only disk with the Oracle code on it and a separate LVM volume for Oracle databases, if they want oracle. We are considering changing our offering when SLES9 comes out. The current proposal is to combine the / and /usr disks into one single minidisk of about 5000 cylinders, being half of a 3390-9. Everything read-write. Then, for service, we can just use ssh to send some commands to the server, link an NFS disk in with all the rpm's and just load the rpms directly on to the server. We can even send ssh commands to recycle various daemons. The only thing we'd have to bring the server all the way down for would be to bring in a new kernel. What we give up to do this is disk space. Each server goes from using 1500 cylinders to 5000 cylinders. However, we're beginning to think that disk is cheaper than labor, especially when it comes to dozens of servers to maintain. YMMV. Give it some thought.

It depends a lot on how well-behaved your applications are in terms of keeping all their files together.

IF your application is well-behaved enough to keep all it's pieces together, then it makes a fair amount of difference. Could you just setup Links to specific disks in VM for a Guest like if you just wanted to share the binaries for say Oracle, or the /usr directory or /home directory? No, because in the case of Oracle and a lot of the ISV software you mentioned, the application wants to dump code outside the directory that holds the main binaries. You also need to have write access to the RPM catalog and some other stuff (something I consider to be a design flaw in RPM -- no provision for concatenated user and system software catalogs). /home is difficult because of the multi-system caching problem -- virtal machines are really separate systems, and each does separate caches of R/W data that are completely ignorant of each other. Without something like AFS or GFS to coordinate writes, you get bad corruption problems. Best solution there is to use NFS or one of the more sophisticated filesystems mentioned previously to handle /home. Wouldn't this accomplish the same thing? What would be the best way to go about this? See above. You're somewhat mixing up two problems: shared resources and operational maintenance. The basevol/guestvol concept is attempting to handle the operational maintenance problem (ie, how do you distribute fixes and do configuration control). Sharing disks takes it into configuration management (how do I share binaries, but deal with the fact that the applications expect stuff to appear in places outside the directory holding the binaries). Best is a hard thing to define. What I'd suggest is: 1) Use the

Re: Progress on PL/1 for Linux
One could say the same thing about Java. That the language wasn't well
conceived.
Actually, one can make the case that NO computer language is really well-conceived.
Of all the languages I've learned over the years, none is really universal in nature
and will handle all possible situations with ease of programming. My current list of
languages includes
Fortran (my first, back in the '60's)
Cobol
Basic
RPGII (probably the worst of the bunch)
Various assembler languages for various platforms
Algol
APL (puh-LEEZE!)
PL/I(Is it fortran or cobol?)
C (but not C++)
Unix Shell Script
Rexx/Regina (My favorite)
Java
Perl
Applescript
And I find that none of them will do everything I want to. So I end up coding in
whatever language I can get the task done most quickly and easily. Sometimes it's
Rexx, sometimes it's assembler, sometimes it's fortran, sometimes it's C, sometimes
it's shell script. Makes for Job Security, because often I'll have one module call
another and they're not written in the same language and no one but me can follow it.
