Re: Redhat Linux 2.4.9 Hanging
I have worked around the problem. I had forgotten that October 3 was the first IPL after we applied RSU 0402 to our z/VM 3.1.0 system. Previously, we were at RSU 0102. It appears that something in RSU 0402 changed the DIAG interface, causing Linux to hang when accessing the swap device. Changing the swap device to FBA has fixed the problem. Thanks to everyone for their suggestions.

iptables shutdown problems
Hello. This past weekend I added hipersockets to our system. We are running two lpars, one with a regular processor and the other an IFL. I've got everything working; I'm able to ping both lpars, etc. The problem I'm having is when I shut down the Linux (running under VM running in the IFL), it gets stuck at the iptables termination. I've had this problem in the past on another linux but it was intermittent. On this linux, it happens every time. We eventually will be moving some production process to this linux and I need to resolve this issue. So . . . when a linux is shut down and it gets stuck at the iptables termination, a) what is causing it and b) how can I fix it?

Re: Performance of linux on zVM does not compare to x86
Don't let the compile times scare you. It is long established that the zSeres processors are not the fastest on the market, far from it. What you gain by running on zSeries is extremely fast internal communications with Hipersockets and Virtual Switch, high I/O bandwidth (FICON and SCSI disk support) and the economies of scale of being able to run multiple middleware machines with only the license cost of the zSeries CPUs. Will you be able to consolidate all of your x86 machines to zSeries? That greatly depends upon what is running on those machines and how heaily loaded they are. Measuring their current load (before and after) is important. You've touched on one of the best ways to run Linux for zSeries machines, cut back their virtual machine sizes to only what they need. For the most part, ignore that your Linux 'experts' tell you for memory sizes. Chances are they will de-tune your environment. Cut back their size to the point where they just start to swap, then bump it up a LITTLE. Vdisk swap is great for bursts of activity, as long as the swapping is not constant and high, you should be running just fine. Miller, Ila wrote: We have SuSe enterprise linux 9 running on 6 zVM partitions. We are running VM in an IFL - one cpu on a z900. One linux is the clone copy that is pushed out to clone the other partitions. One linux clone is running a mail relay that isn't very busy. Three linux are running apache, tomcat, ant, cvs, and java. These are not in production yet and are not doing much of anything other than running all the applications. One linux is supposed to be a Tivoli Gateway, but we continue to have problems with Tivoli and Enterprise Linux 9. It appears a compile on any of the linux takes a very long time and compares to a Pentium III processor speed. Is this what we can expect running linux under zVM? We were anticipating we could eliminate 10 x86 servers at least. Even though we were given a deal on the IFL, if it cannot run 5-6 linux partitions, it does not make sense to add the overhead of maintaining zVM. One of the sys admins 'found a way to achieve the memory restrictions for a Linux guest and still allow Tomcat/java to run. There are a couple of kernel parameters that allow a process to malloc more memory than is phycisally on the machine, specifically /proc/sys/vm/overcommit_memory. We can use this and implement swapping to vdisk. By starting the guests with say 100 MB of RAM, we should be able to limit the amount of RAM used for file buffering. At the very least this should enable us to create smaller footprint guests in RAM terms. However, all that said, I'm still concerned we're trying to get Formula One performance out of a pinto. Are we going down the wrong path trying to run linux under zVM to eliminate all the x86 boxes we have? I would like to have feed back on what kind of performance we can expect to get out of a 1 cpu z/VM on the z900 IFL and how many linux can run there? Ila Z.

Re: Performance of linux on zVM does not compare to x86
Yes, compiles are almost 100% CPU intensive tasks. Mainframes are not the best choice for compute intensive tasks, which is why you have to pick your workload carefully. The other applications you talk about, HTTP serving, Web Application serving, email *are* good choices for the mainframe. Database serving in particular can save you a ton of money if you run Oracle, since they license by the machine and price it the same regardless of architecture.

Finding an not installed file
Weird question, but it may have an easy answer. During a product installation, it said that I was missing libdb.so.2 file. So I go to Yast, and do a search for it. Not there. I queried the vender and was told that I needed the gnome-libs rpm installed. OK, Yast found that. Sure enough, when I installed it, my immediate problem was fixed. But the question is... When you know what file is needed, but not what package it is in, is there a way for Yast (or other command) to scan for that file and say what package it is in?

Re: Performance of linux on zVM does not compare to x86
When planning a move from a collection of distributed systems ( intel, Sun, HP, whatever ) to Linux on zSeries - the question you are asking is not Is Linux on zSeries Faster than platform X? The question is Is Linux on zSeries Fast Enough? In your case - will the Linux systems on your zSeries IFL be able to meet the service requirements that your customers have? The only way to know is to try them out. It looks like you already have some systems running there - ask some of your customers to try the app running on the zSeries Linux instance and see if it meets their needs. The comment that I've always heard from folks new to Z is Where is all this capacity coming from? For a system that has what appears to be a slow CPU, when it comes to real world applications it seems to be able to do more work that you would think. Unless your customers are developers, compiling code is not something that they will be doing on a regular basis so its not a valuable comparision point between intel and zSeries systems. If your customers *are* developers - then isn't it great that you can give them as many virtual machines as they need to do their development work without having to go recable/rewire/repower etc vast racks of machines on the test floor? Once they get used to the idea of a virtual development environment they may not want to go back. If they have to wait a little longer to get their tweak/compile/test cycle done is that offset by the flexibility offered by the virtual environment? In my experience, it is. -- 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

It's not really a filesystem at all. In fact, you can make a file within an arbitrary filesystem be used as swap space, without a loop-back device or anything. Use the swapon -s command to get information about your swap spaces. - MacK. - Edmund R. MacKenty Software Architect Rocket Software, Inc.

Re: Is Swap included in df?
No, it is not.

Just to try running it under strace to see if you can figure out where it is hanging. It could very well be that it's waiting for a response from the MVS system, and not getting it.

Re: Performance of linux on zVM does not compare to x86
Linux on 390 Port LINUX-390@VM.MARIST.EDU írta 2005.11.07 15:09:38 időpontban: Don't let the compile times scare you. It is long established that the zSeres processors are not the fastest on the market, far from it. What you gain by running on zSeries is extremely fast internal communications with Hipersockets and Virtual Switch, high I/O bandwidth (FICON and SCSI disk support) and the economies of scale of being able to run multiple middleware machines with only the license cost of the zSeries CPUs. Running java programs is always cpu intensive.. 1 x86 CPU is _much_ faster than an IFL (on our z800), so to migrate 10 x86 to 1 IFL is not the best idea if you have heavy cpu loads. I have never seen that extremly fast i/o: an x86 can do that also with a storage server.., so if you don't have thousands of users with thousands of opened files x86 will be faster (the same goes to HiperSockets: it's nice, goes with memory speed, but at the end you need a cpu to do something with the sent/arrived data :) I think zSeries may be faster in concurrent operations. You won't have any problems if you see 60-70% system load in top program. And of course we cannot forget the zero-downtime..
