Re: Linux file Shareing
We've been sharing /usr (and sometimes /opt) for about three years on SLES7 and SLES8. It works very well. The only area you have to be careful about is when you add service or upgrades to your images. Adding service or upgrade .rpm's for a product usually means that files get updated on /usr and also in non-/usr areas. If /usr is shared read-only, that means you can't run the rpm on each and every image. You have to run it on some central image that owns /usr. And if you change a disk that other systems access read-only, the other systems will give errors thinking the disk is corrupted, and you won't see the new files until it's remounted anyway, which you probably can't do while the system is running. We are currently using two full-pack 3390-3's for production and upgrade versions of /usr and toggle between them. But that doesn't get all the files. You'll have to copy over all the files that aren't in /usr to each and every image, shut down the image, re-link the disk that points to /usr and reboot. This is turning out to be a lot of trouble just to save some disk space when you have dozens of images. You have to ask yourself, "Is the extra labor involved in the maintenance process justified in light of how cheap disk storage is?" Add to that the fact that many of my customers don't want their Linux server to be taken down for service upgrades and the problem compounds itself. There are companies that sell maintenance solutions that take care of these problems, like Levanta and Aduva. They aren't cheap and they use a lot of system resources. We were evaluating Levanta when management killed it because of cost. Of course, at that time our stock price was about half of what it is now and management was watching every penny. We are actually thinking about going back to a configuration where everything is read-write. Disk is cheap and labor for maintenance isn't. Then we could link to a central NFS server where the rpms are stored and use ssh from a central point to load the service from rpm.

Re: Linux Benchmark
You're making the same mistake everyone does -- comparing apples to wildebeests. Mips are not mips. We go through this every few months, so here it is again: S390 machines are VERY good at handling I/O but are relatively slow in compute power. Intel machines are fast at raw compute power but are very slow in I/O handling. Intel has to do ALL the computing and I/O with its central processor, and probably spends 90% of its time handling I/O. You're comparing the total processing power of an intel box against the central processor only of a mainframe. a 350 mips z800 (we have one) is just the central processor. By the time you add in the processing capability of the channel processors and the processors inside the control units, you might raise that 350 mips to around 30,000 mips -- but only for I/O intensive jobs! If your application is compute intensive (beowulf clusters,engineering calculations, lots of Java), use Intel or HP. If it's I/O intensive (databases, network infrastructure, web processing) the s390 will beat it hands down from Sunday. You also need to consider the cost-per-computing power ratio. My personal pet peeve in our company is when someone sets up a database on a "fast" distributed machine running Unix or Windows, then finds out the "fast" machine can't handle the load, so they bring in another processor to "mirror" the data to allow more people to access it simultaneously. Any time you have 20 copies of the same data being updated, AT LEAST 19 of them will be wrong! Why not put it on a machine that can handle the load in the first place?

Re: SuSE vs Red Hat
Which distribution you want depends entirely on what you're looking for. All three distributions have good support, either from the vendor directly or through third parties. On Intel, Red hat is more popular in the US and SuSE more popular in Europe. Debian is considered by many to be technically the best but third-party software vendors will usually only certify their code for SuSE and/or Red Hat. We're using SuSE because it was the first production supported GA distribution (Red Hat didn't come out with theirs until 9 months later) and it has many features we want that aren't available on other distributions. Oracle, DB2 and WebSphere are certified to run on it. (probably on Red hat, too.) We are getting a lot of pressure from our distributed community to convert to Red Hat simply because all our Intel Linux stuff is on Red Hat and they want us to standardize to them. We, of course, think they ought to standardize to us. Standardization is one consideration. In the US, Red Hat is considered to be the "standard", but it also has somewhat of a reputation on this list for being slightly more difficult to implement than SuSE. The original Marist download distribution (still available, I think) was based on Red Hat 2.2.14. Red Hat has, in the past, declined to include some features such as LVM or OSA support because source code wasn't available. This has, I think, been resolved now, but you need to check to see that the features you want are included. Debian has a reputation for being closer to the cutting edge of newest technology. I haven't worked with it, so I can't speak much to it. "An Optomist is just a pessimist with no job experience." - Scott Adams Gordon W.

Re: Linux cloning - first time
Also don't forget to change your hostname. /etc/HOSTNAME in SLES8. If using Samba, also change it in /etc/smb.conf and, just to be sure, re-run /sbin/SuSEconfig after you've made all the changes to the HOSTNAME and network files. LVM ought to come up automatically in SuSE if you've DDRed the volumes. If not, try vgchange -a If using ssh, I'd also do a rm /etc/ssh/*key* to force SuSE to rebuild all the ssh keys for the new system at its next boot so that you have different and unique ones.

Using crypto cards with Linux
Cross-posted to Linux/390 and VM-ESA lists. Sorry for the duplication. Is anyone out there successfully using a PCICA crypto accelerator card with Linux in an LPAR using IFL's? We have a brand new z800 that has one LPAR set aside with two IFL engines and two PCICA crypto accelerator cards. We just had our IBM CE install the microcode to drive the cards and completely bring up the processor from a powered-off state. Per the IBM redbook SG24-6870-00 "zSeries Crypto Guide Update April 2003", when we go to the HMC and open the LPAR image and select the "processor" tab, we should see our two IFL processors - which we do - and entries to select crypto processors, which we don't. This information is not there on the page. The Crypto tab shows the LPAR number selected, but there is no PCI Crypto tab. The interesting thing is that these items show up on the other LPARS running VM, but not for the IFLs. the other LPARs are set to "ESA/390" whereas the IFL domains are set to "Linux Only". I thought perhaps maybe crypto doesn't work on IFLs, but previous messages on these lists indicate that it does, as well as page 24 of the above manual: "Linux for zSeries will also support the PCICA card for SSL usage. This applies whether the linux-only modeil is used, or the Integrated Facility for Linux (IFL) on a general purpose model is used, or if linux is running under a normal CP, or if Linux is under VM." My CE and I are obviously missing something. Anyone have any idea what it might be? "An Optimist is just a pessimist with no job experience." - Scott Adams Gordon W.

Re: Using crypto cards with Linux
Ah, but Vic, If I set the LPAR in question to ESA ONLY, will it still run on the dedicated IFLs or will it try to use the 390 processors the other LPARs are using? As far as I can see, LINUX ONLY is the only way to specify that an LPAR run on IFLs. "An Optimist is just a pessimist with no job experience." - Scott Adams Gordon W.

FW: Using crypto cards with Linux
Never mind. In looking at the HMC I see on the LPAR image profile that I can select IFLs on the processor tab. I'll try the ESA/390 next chance I get.

Re: Is there is an editor
If you don't want to hassle with "ed" and don't want to go to the trouble of licensing (free or not) "ned", I've found that the "rpl" package from Laffey computer fulfills most of the requirements stated here. see http://www.laffeycomputer.com/ This is a package that just replaces a string in a file with another string.

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.

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.

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.

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: Securing VM using LDAP?
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. 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? You could farm it out, but, frankly, buying RACF or VMSecure would be cheaper. "An Optimist is just a Pessimist with no job experience" - Scott Adams Gordon W.

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.

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: 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.

You can probably fix this problem by recompiling the source under 2.6 and putting the result in the proper library. That's what I did to get it to work under 2.4.21.

alias in SLES9
Here's a wierd one: I issue the command alias x="/usr/bin/the" to set up a shortcut for the hessling editor. It works from the command line. The same command placed inside /etc/profile.local doesn't create the alias. /etc/profile.local has read/execute permissions for everyone and other commands in there do execute.

Re: "DMSACP112S T(152) device error" normal for Linux mini disk?
Again, here's where NFS comes in handy. Both CMS and Linux understand NFS and each can mount the other's filesystems read-only or read-write. (with caveats.) It may be a bit slow, though. NFS on Linux is easy. NFS on CMS is not so easy, but doable. Investigate this as an option. In fact, it may be the only option if you want two-way file sharing between CMS and Linux.

>Rick WOULD have except that he's supposed to spend more time on things that his employer might reap revenue from. Rick, You mean your management actually knows what you're doing? What I TELL my management I'm working on and what I'm actually doing may or may not have any relevance to each other. That's if they ever decide to drop by. I haven't seen a manager in this room of 17 people since before Christmas. Quite frankly, I doubt that some members my management would know if I was working on VM, working on Linux, or running a music-download service off the Cray, even if they were standing behind me looking over my shoulder. Some of them are not very technically-literate. You mean you have managers who understand technical stuff? I always thought the main requirements for being in management in ANY company was having nice hair and a large bladder capacity for sitting through meetings.

Diag disks disappear
Hi, gang: We're trying to use the DIAG driver on disks in SLES8. We have the DIAG driver installed as a kernel module. We CMS FORMAT/RESERVE (blocksize 4096) the minidisk before giving it to Linux. We do NOT dasdfmt the disk. We place an ext3 filesystem on the device with mke2fs -j -b 4096 We mount the filesystem and are able to use it. It is placed in /etc/fstab. cat /proc/dasd/devices shows the device as using the DIAG driver. Performance toolkit shows the device as using minidisk cache. Now, reboot the server now cat /proc/dasd/devices shows the device as using the ECKD driver. Performance toolkit shows the device as no longer using minidisk cache. What gives? What are we doing wrong?

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: Poll Results
We have 2 IFLs, 6GB main storage, 2GB Xstore, and the workload is all over the place. You name it, we've probably got a server doing it. Samba, Java, NFS, Apache, Tomcat, J2EE, virus scanning, Oracle, MySQL, new software development. Just about anything. We even have one server dedicated to monitoring the performance of the others.

Re: Putty users
I could do that, but I'd have to pay for it out of my own pocket. The company won't. Processor upgrade, memory upgrade, video card, USB/firewire card and bigger (SCSI) disk drive would probably run me over half a grand. Upgrading program products to run OSX would probably go more than the other half. Maybe I can just peel up the inventory tag on the 8600 and put it on my G4 powerbook.

Re: Running Linux SUSE9 without a SWAP file
Or better yet, put your swap in z/VM Virtual-disk-in-storage. It becomes part of VM's paging storage, and will be created at logon time, but not used unless you actually need the swap space. There is a HOW-TO on how to do this at http://linuxvm.org/Info/HOWTOs/vdiskswp.html and look up the SWAPGEN EXEC on the Sine Nomine website.

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.

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? Are there any problems with using the diag module on 64-bit SLES9? "A statesman is a dead politician.

Re: CPINT Question
I have a different, but related question: in SLES8, if I have in my zipl.conf dasd=292-2AF, and I "hcp link linux5 292 298 mr" the link is performed (VMSECURE RULES allows the link), and if I immediately look in /proc/dasd/devices, I show the new 298 disk as active at /dev/dasdg. I can then mount dasdg and work with it. Now, in SLES9 with the same zipl.conf information, If I do the link "hcp link linux5 292 298 mr" the link is performed, but the 298 does not appear as active in /proc/dasd/devices. Anyone know what the difference is? Am I missing something? "A statesman is a dead politician.

SLES9 nmb going nuts!
I am in the process of getting SLES9 up and running. Samba is installed and working. However, every few seconds nmbd comes up and does something. I get the following on the system console: Mar 22 09:36:14 lnx5 nmbd 2500 : 2005/03/22 09:36:14, 0 nmbd/nmbd_packets .c:process_nmb_request(1480) Mar 22 09:36:14 lnx5 nmbd 2500 : process_nmb_request: Multihomed registra request must be directed at a WINS server. It will do this about 5 times and then stop, and do it again 5 seconds later. It's using about 40% of the cpu and you can't even log in when it starts doing this. If I'm already logged in, I can see nmbd come up in top. Can anyone tell me what this means? "A statesman is a dead politician.

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? .

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.

Using IFL processor
We just recently upgraded to a G5 processor and got an IFL engine with the other processors. Just last night I did an I/O gen with an IOCDS that created a separate LPAR that will run z/VM 4.2 and will eventually have all of our Linux servers as guests on this one z/VM LPAR. We have just obtained z/VM 4.2 (currently running on z/VM 3.1.0 on our other LPARs) and so we can't test this new LPAR yet since we don't have a VM that will IPL on it yet. We have five other LPARs that share three 390 processors, but we want the Linux LPAR to use just the IFL processor. Since I've never done this before with an IFL processor, my question is, how do I tell the LPAR controls to use the IFL engine for this LPAR? When creating the LPAR image profile on the HMC console, under the "General" tab, I went into the "Mode" window and I see four choices there: ESA/390 ESA/390 TPF Coupling Facility Linux Only Do I choose the IFL engine by selecting 'Linux Only"? I don't see any other choice anywhere in the image profile that would indicate an IFL processor. Is there something else I have to do? Should I dedicate this processor to the LPAR? The only manual we have for the HMC is for our old G4 processor. I'd appreciate any help from someone who's done this before, or perhaps someone from IBM who's in the know.

Installing Websphere Commerce Suite and DB2 on Linux
We've just obtained an evaluation copy of Websphere Commerce Suite and DB2 for Linux/390. We are currently using SuSE 7.0 with the 2.2.16 kernel until our order for SuSE 7.2 arrives. The install manual is a bit vague about how much disk space is needed, just saying it needs 1 volume for Linux and 1 volume for the product, but it doesn't say how it's distributed among the various subdirectories. It also looks like it requires write access to /usr (ours is r/o shared commonly) so I'll have to create a separate /usr volume for this virtual server. >From anyone who has installed this and has it running:How much disk space do I really need for /home? /opt? any other subdirectory under root used heavily by these products? And what's the minimum virtual storage I can get away with? The manual specifies 1GB, and that's as big as our whole VM LPAR. We'd end up stealing like crazy.

Re: swap file alloc
You can also use V-disk for swap. This doesn't use any allocated disk, but puts your swap into virtual storage, which means into XSTORE and paging DASD. It requires a little setup, but is much faster than Linux DASD swapping. The following example assumes you boot from the 292 disk (dasdb) and use the 293 disk (dasda) for swap. Your /boot/parmfile should reflect this. In the VM Directory for the Linux server, add MDISK 293 FB-512 V-DISK 25 MR LINUXSWAP DASDA Then in the Linux Server's PROFILE EXEC, you will have to add queue '1' queue 'LXSWAP' 'FORMAT 293 E ( BLK 4096' if rc <> 0 then exit rc queue '1' 'RESERVE LINUX SWAP E6' if rc <> 0 then exit rc 'CP IPL 292 CLEAR' Then you have to modify the /sbin/init.d/boot file as follows: (about line 150 in SuSE 2.2.16) #cho "Activating swap-devices in /etc/fstab..."#wapon -a &> /dev/nullecho "Formatting T-DISK swap partition"dasdfmt -b 4096 -y -f /dev/dasdaecho "Creating swap file signature"mkswap /dev/dasda1echo "Activating swap partition"swapon /dev/dasda1 Then when you IPL CMS for the Linux server, it will create a CMS RESERVED V-disk for Linux, and then boot the 292 disk. During the Linux boot, Linux will format the 293 for Linux and create a swap partition on it and use it.

Mounting multiple .iso images for YAST
I'd like to set up one of my Linux images as a server for the .iso images for SuSE package install. That way I can turn over package installation to the owners of the various Linux sevrers. I've got the three .iso images in a /home directory on one linux server. I know how to mount an .iso file using loopback to a mount point. The question is, how do I organize the mount points so that YAST on another machine can ftp to it and get the first CD, and then when YAST needs the second CD, go to that one automatically? I've looked all over the list archives to find this. Is it just /cdrom/SuSE/CD1 /cdrom/SuSE/CD2 /cdrom/SuSE/CD3?

Re: Current Linux/390 Distributions Aren't Cheap
The Linux pricing issue works both ways, though. A recent post said that there were about 700 Linux/390 installations world-wide (300 production and 400 in test). If SuSE sells one copy at $100 to each installation, that's only $70,000 to cover research, creation of the kernel, packaging of all the program products that go with it, testing and quality assurance to make sure it all works together, development of YAST and other products, packaging on CD, manuals, crating, storage and shipping. These days $70,000 won't even pay for one employee with benefits, and you're not going to do all that with one employee and still get out a new release every year in 20 diferent languages. Remember, this is a complete operating system and all associated program products. How much are you paying for VM and all its software, including maintenance? At $11,500 an engine, SuSE Linux can be considered a bargain in comparison! We're all just spoiled because we've been able to get it free from Marist or SuSE for two years. When was the last time the Marist distribution was updated? How many program products come with it? You can still get Red Hat for free, but it's a partial distribution with few or no program products. And Red Hat has stated that if it can't make money it will get back out of the business. We don't have the manpower here at Boeing to compile our own kernels, research and install/compile program products and try to figure them out without any manuals. We need a prepackaged solution. (There's only 8 of us to handle all of VM/CMS and Linux/390 and all program products, performance and tech support for 6 LPARS and 45,000 users. Five years ago we had 19 people doing this, half the load and no Linux.) Other distributions are incomplete. TurboLinux, you have to compile your own kernel and obtain and install your own program products. Same with most of the other distributions like Cayman and Debian. Red Hat has the whole OCO problem with OSA, no support for LVM, and the Beta Oracle will only run on SuSE at this time. (We do a LOT of Oracle on VM and Oracle isn't enhancing the product for VM/CMS.) If SuSE can't make money on the product, there is no reason for them to stay in the business at all. If you've been following the financial news, you may have noticed that SuSE, GMBH has been having some problems (like the rest of the world), alleviated only by a large infusion of cash from IBM. I agree that the current situation is inconvenient, but SuSE has to have SOME way of supporting their investment in time in the product. How would you all suggest they make money on the deal, or should they just do it out of the goodness of their heart? I haven't heard anyone actually suggest a new business model for SuSE based on cheap prices, just whining about the new price. I predict that other commercial distributions will follow in SuSE's footsteps and raise prices on S/390 distributions to the same general level. Either that or go out of business. The non-commercial distributions will continue to plod along, having you do most of the work and putting out new releases whenever they can get around to it. Take your choice: an "overpriced" product, a product where you do all of the work (and whose vendor may not be around a year from now), or no product at all.

Seems to me, then, the solution is simple. 1. Download one of the "free distributions" (like I did - Marist orginally, then SuSE because that's all there was until recently. I probably would have stayed on Marist if they hadn't been stuck on the 2.2.14 kernel.), 2. Spend two years getting it to work as a production system with no manuals and no help other than this list and a few presentations at SHARE (like I did), 3. Finally convince management with this proof-of-concept (like I did - or at least am still doing) and then 4. Evaluate all the full systems to find the best for your needs and buy this full-featured system with full support (like I did). It may not be the same system you evaluated. We seriously considered Red Hat until we found that there was no guarantee Oracle would work with it. p.s.

Re: IBM announces LINUX-only 1 to 4 engine zSeries
Me too. I spent a good part of my career in VM migrating users and applications off of many VM/IS 9370's onto our big VM/HPO-VMXA-VMESA mainframe. Five or six of them, as I recall. We actually had to do a fast migrate of one in October of 1999 when the user was finally convinced that none of the hardware, operating system, program products or applications were Y2K compliant and they would just STOP in three months. They went from VM/IS (nee VM/SP 5) to VM/ESA 2.3.0. I think that's a jump of something like 9 or 11 releases.

Re: NT server consolidation with samba
For the benefit of those of us who are only too ready to admit all our ignorance when it comes to Linux on the Mainframe, could someone explain what ACLs (Access Control Lists are and how they relate to SAMBA? We had a set of NT servers lately that we wanted to migrate to Linux/390 SAMBA for cost purposes. The cost savings would have been enormous. The NT weenies did everything they could to shut us up and "prove" that we couldn't do the job, desparately looking for anything and everything that NT could do that SAMBA couldn't. They finally focused on the fact that individual NT users can define, by userid, who has what privileges on each file in their shared folder and SAMBA can't do that unless the administrator goes in and does it for them. They managed to turn it into a show-stopper for us. Could ACLs do this for us? If so , where do we get it for 390 Linux?

Logical Volume disappears at reboot.
I'm having a very strange problem. I needed to make a public repository for the contents of five CD's, so I set up a Linux server using SuSE 2.2.16. For five CD's, I figured two volumes ought to hold the contents. I added two 3390-3 full-pack volumes to Linux and did a dasdfmt on them. I went into YAST and created a logical volume group "vgcd" and a logical volume "lvcd" using these two volumes. I did a mke2fs on the logical volume /dev/vgcd/lvcd I was able to mount /dev/vgcd/lvcd as /mnt and was able to do a "df' and see them and copy some files to them So far, so good. Everything looking just fine. Now, the wierd part: I manually umounted /dev/vgcd/lvcd, shut down and rebooted Linux. After the reboot, the device /dev/vgcd/lvcd does not exist. vgscan says "vgscan -- no volume groups found" pvscan says "pvscan -- no valid physical volumes found" vgck says "vgck -- no volume groups found" pvdisplay /dev/vgcd/lvcd says "invalid physical volume name "/dev/vgcd/lvcd" ls /dev/lvcd says "No such file or directory" If I go back into YAST to do it all over, it says I can't create volume group "vgcd" because it already exists. But it doesn't show up in the list of volume groups. Can anyone point me to where I might find out why I can't keep a logical volume? "Never trust any computer you can lift."

Re: Using IFL processor
Crossposted to Linux on 390 port list and VM/ESA list. Sorry for the duplicates. About two months ago I wrote to this list asking about how to set up VM to run on an IFL processor. We've finally got z/VM 4.2.0 up to where we can IPL it in a new LPAR. We have a 9672-r36 with an IFL engine and we want to run it in the new LPAR on a dedicated IFL engine. In the HMC we've defined the LPAR to be "Linux Only" in the General tab of the LPAR image profile. Activating the image profile we even get a cute little icon with a penguin on it in the list of CPC images. However, it will not IPL if we set up the processor for the LPAR as "dedicated central processors" on the "processor" tab of the image profile (says no processors are available and to free one up from the other LPARs). It -will- IPL if we set this up as "dedicated integrated coupling facilities processor". So far, so good. However, looking at the SAM monitor shows CP0 CP1 and CP2 (our 390 processors on this box) active, but CP3 as not active. Furthermore, if we start a program on the Linux/zVM420 LPAR running that chews up CPU time - VM in the LPAR shows 94% active - we note that CP0, CP1 and CP2 increase their bars in the SAM monitor and CP3 does not. If we stop the program, the bars return to normal. It appears that we are NOT running on the IFL engine! Has anyone actually gotten z/VM 4.2.0 to run on an IFL engine in a G5 processor? If so, how did you do it? "Never trust any computer you can lift."

Re: Using IFL processor
You misunderstood. We have five LPARs running on three S/390 engines. We want to create a sixth LPAR running on a dedicated IFL engine with z/VM 4.2 running Linux guests. The LPAR is up, but we don't think it's running on the IFL engine, even though we've told it it's a Linux LPAR. "Never trust any computer you can lift."

Partitioning DASD
Can someone run me through the steps for partitioning a minidisk in Linux? I have SuSE 2.4.7 and a 200 cylinder minidisk accessed as /dev/dasdf and tried dasdfmt -d cdl -b 4096 -f /dev/dasdf (also tried -d ldl) fdasd -c /root/dasd.conf mke2fs -b 4096 /dev/dasdf1 mke2fs -b 4096 /dev/dasdf2 in the case of dasdfmt -d cdl mke2fs says both partitions are zero size. In the case of dasdfmtn -d ldl mke2fs says dasdf2 is zero size. What am I missing? "Never trust any computer you can lift." Gordon Wolfe, Ph.D. (425)865-5940 VM Technical Services, The Boeing Company
Re: Linux for S/390 recommended and experimental bux fixes for s3 90-tools and kernel 2.2.20
I'm in the process of trying to install the "jiffies patch" from the developerworks site below for SuSE Linux 2.4.7. I got the .tar.gz files and un-tar-ed them. I placed the file linux-2.4.7-timer-3.diff in the /usr/src/linux directory, did a cd to that directory and did a patch -p1 -R < linux-2.4.7-timer-3.diff Most of the patches applied, but a few did not. I get these messages: patching file arch/s390/config.in Hunk #1 succeeded at 51 (offset -1 lines). patching file arch/s390/defconfig Hunk #1 succeeded at 43 (offset -1 lines). patching file arch/s390/kernel/entry.S Hunk #7 FAILED at 297. Hunk #15 succeeded at 891 with fuzz 2. 1 out of 15 hunks FAILED -- saving rejects to file arch/s390/kernel/entry.S.rej patching file arch/s390/kernel/s390_ext.c patching file arch/s390/kernel/s390_ksyms.c Hunk #1 FAILED at 57. 1 out of 1 hunk FAILED -- saving rejects to file arch/s390/kernel/s390_ksyms.c.r patching file arch/s390/kernel/setup.c patching file arch/s390/kernel/smp.c and so on. I'm not really that familiar with the patch and diff process. Why do some work and not others? Can anyone point me in the right direction? "Never trust any computer you can lift."
