Re: Any real world WebSphere ND guidance?
We have about 25 WAS servers running PEGA on zLinux. We created two zVM LPARS and clustered WAS across the two; this has worked really well allowing us to do maintenance on individual servers or zVM LPARS with no service interruptions. The biggest frustration we have had is reconciling zLinux memory and java heap sizes, the Heap Sizes seem to prefer to think in intel memory. -Original Message- From: Linux on 390 Port [mailto:LINUX-390@VM.MARIST.EDU] On Behalf Of Mrohs, Ray (JMD) Sent: Monday, April 22, 2013 10:37 AM To: LINUX-390@VM.MARIST.EDU Subject: Any real world WebSphere ND guidance?

Re: Any real world WebSphere ND guidance?
Easy and Websphere seldom co-exist in the same paragraph. 8.5ND has some nice new bells and whistles. It's also proportionately more of a hog. Their clustering implementation has a number of poll till I get what I want cases. It is aware of the application-layer stuff, so can do some other tricks. I'd investigate the Linux clustering possibilities first. Then you'd have a general purpose solution rather than a one-trick pony. From what you describe, sounds like you're not going to see a lot of upsides other than the capability to add cluster members easily if/when you get another system or LPAR.

Re: Any real world WebSphere ND guidance?
I would argue that WAS ND on zLinux is much simpler than clustering across a bunch of x86 servers. We've been doing Websphere ND on zLinux for 4-5 years with WAS 6.0, 6.1, 7.0, and 8.5. The biggest advantage is scalability of each host. We run 85 Websphere instances across 5 hosts with the DMGR on it's own 6th host. And this scalability is key, because maintaining 5 Websphere installations is much easier than managing 85 Websphere installations For production, we cluster but do not load balance. We've found plenty of scalability with running the workload on a single instance of each prod server, and the clustering is simply for failover. This makes debugging massively easier than trying to troubleshoot on what instance a problem occurred. Just for context, our volume is about 2,000,000 servlet hits per day. I don't have as good of a count on EJB's. Because of that scalability, we will not have much of a need to use the new dynamic clustering in WAS 8.5 until a bigger load comes along. Having your Websphere logs in the same place makes it easy to give your developers access via a simple common interface. Automated change control is simpler in our case, as that single DMGR can push code to any of the 85 servers. And we just have to put the prod application property configuration files in a single (plus the failover) location that prod server instances share. There's more, but I don't want to write a book. Downsides The biggest downside is that wsadmin installation is CPU expensive! zVM is extremely simple, but not intuitive and as easy to find answers on the internet as other OS's.

FW: Any real world WebSphere ND guidance?
Actually, I forgot by far the largest downside - 3rd party vendor support both for purchased java applications and also for extra support infrastructure (like backups or whatever). Though that really depends on who your vendors are. We have had to push vendors to support the mainframe and many of them were reluctant to try. But we have never had anything that had errors due to it being on zLinux. It's more a vendor comfort level thing. Jon -Original Message- From: Veencamp, Jonathon D.

WebSphere Application Server Horizontal Versus Vertical JVM Stacking Report The following paper is available at : developerWorks (pdf) http://www.ibm.com/developerworks/linux/linux390/perf/tuning_webapp.html#hv TechDocs (pdf) http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP102077 IBM Information Center for Linux (html) http://publib.boulder.ibm.com/infocenter/lnxinfo/v3r0m0/topic/liaag/l0wasg00_2012.htm This paper presents performance data for a test that compares the effects of stacking 200 WebSphere Application Servers. The question is whether it is better to host all WebSphere Application Servers on a single (vertical stacking) z/VM® guest, or distribute the servers across multiple guests (horizontal stacking). As an additional test, the use of shared mini-disks or a DCSS for the WebSphere installation was analyzed, to determine if there are criteria that favor one or the other setup.

Re: zLinux / WebSphere spinup times
Are you paging? Do you have SRM STORBUF set higher than the default? If you are paging are you keeping the page space 50% full and well spread over your I/O system? Does your perf monitor tell you what your servers are waiting on? How'd you size the servers virtual mem requirements and their JVM sizes? (It is a huge challenge to get server people to realize that bigger is not always better). There's lots of areas where things might be configured less than optimally.

Re: New Performance Whitepaper:: WebSphere on IBM System z 64-bit/31-bit Studies with J2EE Workloads
I was reading this new paper... There was a discussion on this list about vm.swappiness a while ago. We had found with it at 60, our biggest app would just continue to march through its swap space and keep increasing its size. We found things happier at 60. But I never did get a good feeling about what this setting really did. This study recommends setting it to zero. from paper Setting swappiness to zero These instructions are used to set the swappiness parameter to zero. The swappiness parameter influences the kernel preference to move memory pages from applications to swap page, versus reclaiming memory from the cache. After system restart, set the swappiness parameter to zero. This ensures that if memory is constrained, the page cache is reduced in an attempt to recover memory, before application pages are moved to swap space: +--+ |echo 0 /proc/sys/vm/swappiness +-+ This setting may improve or degrade the performance of an application. Since there is adequate memory already dedicated to this workload, large amounts of memory would not need to be swapped to disk anyway. Since precautionary 'early' swapping is now avoided, our results should be free of the effects of this kind of swapping. /from paper?

Since precautionary 'early' swapping is now avoided, our results should be free of the effects of this kind of swapping. As I interpret the paper, the author concludes that for this particular workload the setting is appropriate because they have plenty of memory anyway (I am tempted to think that if you have plenty of memory, Linux memory management would not need a helping hand...) Wouldn't this always be a good thing under VM to force it to reduce its memory footprint? Are there cases where it wouldn't be? I spent some more time on this lately and I believe that for Linux on z/VM the proper setting would be 0. But I did not have time yet to set up tests to show the benefits with real numbers. And I don't really like presenting theory without the numbers. My motivation for disabling swappiness is not the same as in that paper, but because of the double layer of memory management. It will probably require a slightly larger virtual machine, but the good part of it is that VM can page those parts out. The memory cost of the virtual machine remains the same, but it takes less paging to get there. For this to work well, idle virtual machines must drop from queue. When Linux does not go idle according to VM, memory management is pretty random and you probably will not notice the effect. So I would mainly suggest this for Linux guests that have low utilization and drop from queue when idle.

Re: WebSphere Application Server for zLinux
Probably a bad idea I think, the garbage collector will take a long time and might have an impact on response times. I'm not an expert on this but what I hear from others here is far from 10 GB, more like 500MB-1GB but I don't know any details abouth their applications.

We've had excellent performance with 4 GB and larger JVMs; our experience with the 1.5 JVM in WAS 6.1 is that you can get excellent performance with large memory allocations. Note, though, that can be dependent on the application. I would be more concerned about the large session sizes - if you're using clustering between guests you'll quite likely see high CPU use serialising sessions that large. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

I am trying to get some scripts set
up to start / stop DB2, MQ and Websphere applications. The
scripts I have are in this format:
#! /bin/bash
set -x
case $1 in
'start')
/bin/su - udbdb1 -c

'restart')
stop
start
;;
*)
echo $Usage: $0
{start|stop|restart}
exit 1
;;
Esac
This is failing because the environment variables are not
set up correctly (-1390 reason 3 return code). Any
suggestions on how to fix this?
I have found a way to initiate this with:
sudo -u udbdb1 -i /etc/init.d/db2 start
The problem with this is that I cannot find a way to
implement this in the /etc/sudoers file so a non-privileged
user can run the command.
Any suggestions on how to make either of these methods work
will be greatly appreciated.

/etc/init.d start/stop scripts for DB2 MQ and Websphere
I am trying to get some scripts set up to start / stop DB2, MQ and Websphere
applications. The scripts I have are in this format:
#! /bin/bash
set -x
case $1 in
'start')
/bin/su - udbdb1 -c /home/udbdb1/sqllib/adm/db2start
;;
'stop')
/bin/su - udbdb1 -c /home/udbdb1/sqllib/adm/db2stop
;;
'restart')
stop
start
;;
*)
echo $Usage: $0 {start|stop|restart}
exit 1
;;
Esac
This is failing because the environment variables are not set up correctly
(-1390 reason 3 return code). Any suggestions on how to fix this?
I have found a way to initiate this with:
sudo -u udbdb1 -i /etc/init.d/db2 start
The problem with this is that I cannot find a way to implement this in the
/etc/sudoers file so a non-privileged user can run the command.
Any suggestions on how to make either of these methods work will be greatly
appreciated.

New Whitepaper available:: Tuning WebSphere Application Server Cluster with Caching
Tuning WebSphere Application Server Cluster with Caching The paper is available at: TecDocs: http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP101406 developerWorks: http://www-128.ibm.com/developerworks/linux/linux390/perf/tuning_pap_websphere.html#wascc This paper analyzes parameter and configuration variations in a WebSphere® Application Server cluster running the Trade workload when caching is enabled. A secure environment was used with a DMZ to protect the application servers against an uncontrolled external zone. The findings include: Any form for caching resulted in a significant throughput improvement over the no caching case, where Distributed map caching gave in the highest throughput improvement. Dynachache disk-off load can significantly improve the performance with small caches without additional CPU cost. The z/VM® VSWITCH LAN configuration resulted in higher throughput than the Guest LAN feature. The IBM® System z10® system obtained a significant throughput advantage over the IBM® System z9® system They highly recommend z/VM for environments like this.

WebSphere sizing on Linux for System z
We are looking at moving our WebSphere workload from z/OS to Linux. We have lots of 4way x86 Linux boxes running WebSphere - each instance capable of running dozens (nearly 100 in some cases) of application servers (JVMs) with many GB of memory. On WebSphere for z/OS, an LPAR might have 32 application servers collectively collectively using 8GB of memory and 2 zAAPs - not saying that is the max it can run, it's just a sample size of an existing workload. If I move this example Websphere for z/OS workload to zLinux, would it fit on one Linux guest with 8GB of virtual memory and 2 IFL's. Anyone have rules of thumb to offer regarding trying to run a single virtual zLinux for WebSphere with something like 8GB memory and dozens of application servers? This WebSphere design works great for us on x86 and z/OS, so wondering if it holds true on zLinux.

Sounds like you're relying heavily on knowledge that not all the JVMs will ever fire at the same time (on both platforms). If so, then the answer is maybe; you need to measure usage patterns. Otherwise, the answer is probably not, unless you have a fairly large z10. If all those JVMs ever fire at once, you're going to be in a world of pain. You need a lot more information about how those apps and JVMs behave before you can answer the question. The fact you mention that you're already using 2 ZAAPs and you get many fewer JVMs per z/OS tends to worry me already. -- 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
Re: Delayed start of WebSphere
Thanks for the suggestions, all. I got pulled off onto some z/OS work for a while, but I'm back on this now. I think that I will go with the nostart file solution for the quick fix and look at implementing a menued solution later. I'm hoping to set up clustering later for this particular guest, but it will take me a while to get that done. I'm also not sure how well that would work with our uniprocessor configuration.

Delayed start of WebSphere
I have a few Linux guests which run WebSphere. There are times when applying maintenance, etc, that I need to reboot Linux on these guests. If I have WebSphere auto-start during the boot process then every time I boot I have to wait for WAS to finish coming up - something that takes several minutes - before I can even so much as sign on. Obviously, if I need to boot more than once, I end up having wasted a lot of time. What I would like is maybe a way for Linux to finish booting then give me a choice as to whether to start WAS; after a period of time - say, 30 seconds or a minute - it would just go ahead and auto-start WAS.

This would mean no outage. Yes, that's true. I read the question as if I'm testing stuff like operating system patches, how can I skip *some* of the heavyweight startup scripts like WAS w/o taking them out of the configuration or waiting for a full-up system startup every time? The two solutions are actually complementary -- the flag file or sysconfig variable approach lets you leave the system configuration alone (it's those times that you forget to put something back in that wake you at 2 am), but still skip the heavy stuff during testing. The cluster bit lets you keep services up and running; you still need the flag idea to let you control what parts start/stop when you bring a node up and down, but the cluster bit hides the details from the users. -- 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
Re: Delayed start of WebSphere
The following bit of insanity was crafted by myself and my partner in crime
Dave Hansen.
Here's what we have for an environment:
Two production nodes in a cluster, Two QA nodes in a cluster, and two single
node test systems, all running on the same z/VM.
We have a z/VM guest called 'LNXADMIN' on which we created a 192 disk, and
stuck and accessed it as disk 'n'
for each of our linuxes there are two files. an IPL file and a DELAY file:
ABINODJI DELAYN1 F 80 1 1 11/17/06 9:52
ABINODJI IPL N1 V 7 1 1 9/26/07 2:45
The delay file contains an offset in seconds to wait before starting WebSphere.
This only comes into play on a Sunday, since that's the only day of
the month we do scheduled maintenance, and we don't want 6 WebSpheres all
starting at the same time.
* * * Top of File * * *
DELAY=780
* * * End of File * * *
The other file is the 'IPL' file. Which was going to contain anything we wanted
to tell the guest not to do when it was IPL'ed. SO far, we just have a
yes/no for WebSphere in the file:
* * * Top of File * * *
WAS=YES
* * * End of File * * *
We control the entries with a couple of scripts
The script we use takes the parms Y or N and {server name} and sets the server
in question to YES or NO. If no server is passed, it sets ALL of them
to yes or no. Very simple. You can also edit the files manually in a pinch.
The Linux guests uses the CMSFS to access the LNXADMIN 192 disk which has been
CP linked in profile exec at IPL time as 292. There are other options
than CMSFS now, and arguably better, but this isn't broke, so I'm not fixing it.
The was6_start.sh script, which I've included below, reads the IPL file, and if
it's a Sunday, it reads the delay file. IF the IPL parm is set to
WAS=NO then WebSphere will not be started. If the 292 disk is not present,
WebSphere will be started. If the parm is WAS=YES, WebSphere will be
started. We can manually start WebSphere with the script websphere_start which
does stuff like:
echo -e \nStarting Deployment Manager
/opt/wasprofile/DeploymentManager/bin/startManager.sh -replacelog
echo -e \nStarting Node Agent
/opt/wasprofile/AppServer/bin/startNode.sh -replacelog -nowait
echo -e \nStarting Application server 'server1'
/opt/wasprofile/AppServer/bin/startServer.sh server1 -replacelog

Websphere support of HATS (was: JBoss, Anyone?)
Subject changed... sorry Mark... :) Tom Duerbusch wrote: However, are you saying that if we were only running HATS and the part of WebSphere that comes with HATS, that I need no knowledge, what-so-ever of Websphere to make it run fine in a production environment? Correct. Any support of the Websphere component that makes up HATS is done by the support center, not the customer (unless the support center directs the customer to do some Websphere thing on their behalf). The gist(s) of my concerns are: 1. We end up having to support multiple Java platforms. 2. With multiple platforms, come the need to support, installation, maintenance, performance, debugging of multiple platforms. 3. With each platform comes the need (IMHO) of one or more test platforms. 4. And with each flavor of Java platform, we have some licensing fees (product, support, etc) on a per engine basis. In this case, licensing multiple products, that apparently do the same thing, on the same single engine, when there is no application driven reason to do so. Welcome to multi-cultural computing... :) I don't have an easy answer. What you need to acquire and support is a business decision and needs to be evaluated based on the needs of the enterprise. Am I right about this... That the full blown Websphere, can do: 1. HATS It is entirely possible that HATS will ONLY be supported with Websphere that is delivered with HATS. Any other Websphere packages that are installed and used with HATS (even if they are the same level) will not provide a supported environment. 2. Any in-house developed application that uses Oracle 10g. In as much as your Websphere applications need to use the Oracle database, sure. 3. Any thing that we would have used Jboss for. A second question, other than a cost issue, is there any thing you would use Jboss for that wouldn't work just as well on Websphere? I can't answer those. I would expect that there are things that can be done in Websphere that can not be done in JBoss and vice-versa. -- Rich Smrcina VM Assist, Inc.

WebSphere, SLES 9 64 bit and Above/below the bar strangeness
Greetings. This may be 'working as designed' but I'm not sure If anyone has seen this please feel free to enlighten. We have a WebSphere cluster, with WebSphere in Network Deployment configuration. This means that the primary node has a configuration slightly different than the secondary node in that the primary has a deployment manager task. That in and of itself causes a nearly 600 meg difference in memory footprint. WebSphere on Linux for z/Series is a 31 bit task, running in a 64 bit operating system. I've verified that both machines are at the same maintenance level, and both are indeed 64 bit SLES. So the conundrum here is why would the node with the deployment manager consistently have almost twice as many resident pages above the bar as the node without the Deployment manager? Is there some function of the Deployment manager that would request memory above the bar to a much greater extent than the node agent or the app server tasks? Just curious as we'd like to explain the behavior difference. -J -- 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

JBoss? WebSphere?
Can anyone give me a brief description of what JBoss is? We are apparently going to need it in conjunction with a project we have here that involves using WebSphere Application Server and HATS to front-end some of our CICS applications.

You're right, it is a J2EE web app server. Someone may be getting confused about real requirements versus what I heard was...

Websphere
I'm prepping for an trial install of Websphere. This is on an IFL. As it turns out, the Websphere trial for Windows and Linux that anyone can down load, the Linux one, which looks like an Intel version, is a common install and is suppose to work for zLinux systems also. Wish it would have said that on the web site. I lost a couple weeks trying to locate a zLinux version of Websphere to trial. Anyway Any problems/headaches or other words of advice anyone wishs to share about Websphere on zLinux? This will be on SUSE 9. 31 or 64 bit for Websphere? I can start the install on z/VM 5.1, but I have z/VM 5.2 on second level. Should I wait to install Websphere until I'm on z/VM 5.2? As this is just a test, I plan on installing everything in the same package (that is the Java machine along with the webserver). Big mistake? If we start to go the route of Websphere, I, most likely will install it over a dozen times in the next year. Different variations of dasd setup and machine setup, to see which meets our needs best and also to allow me to take baby steps in implimenting new technology.

I'd recommend putting your logs on a sep minidisk (filesystem) or at least setting it so they don't exceed a certain size. We've only done 64bit.

Re: Websphere
Any problems/headaches or other words of advice anyone wishs to share about Websphere on zLinux? 1) Websphere expands to fill all available resources, both human and machine. Plan on it. 2) Make sure you have plenty of contiguous page space. Virtual machines containing WAS tend to be very large. 3) Have a Java profiler handy. Much of the animal product that doubles as application programs that you'll be handed from the small-systems world worked acceptably there because CPU cycles were low-cost. Stupid programming techniques will become highly visible very quickly in this environment, and without evidence that it's the program, stupid, it will be your fault. This will be on SUSE 9. 31 or 64 bit for Websphere? 64-bit. Helps ameliorate #1. I can start the install on z/VM 5.1, but I have z/VM 5.2 on second level. Should I wait to install Websphere until I'm on z/VM 5.2? If you can, wait until you have 5.2 up. WAS machines often rapidly expand beyond 2G, and you'll see the 2G limitations of 5.1 very quickly after that point. As this is just a test, I plan on installing everything in the same package (that is the Java machine along with the webserver). Big mistake? Not huge, but warps your test results somewhat -- philosophically, it's always better to start as you mean to continue, and splitting things up also allows you to demonstrate the ability to construct both production and test environments on the same system. Having multiple small instances for VM to juggle is usually better than a small number of ginormous instances. It's where you want to manage the complexity (inside WAS or at the VM layer). The separate machines also give you finer control over resource utilization caps for different pieces of the app. If we start to go the route of Websphere, I, most likely will install it over a dozen times in the next year. Different variations of dasd setup and machine setup, to see which meets our needs best and also to allow me to take baby steps in implimenting new technology. Another reason for small, separate servers. You can have different virtual machine configurations in the same WAS server farm and see which one works best. You can then take the others out of the WAS cluster with only a little pain, rebuild them in the way that works best, and bring them back. Consider carefully whether you really need all that WAS overhead for your apps.

Stupid programming techniques will become highly visible very quickly in this environment, and without evidence that it's the program, stupid, it will be your fault. Very good point. Programmers do crazy things when they are used to having the whole machine to themselves - real life example a) Let's wake up every 2 seconds and see if such and such process is alive b) Let's run log scanning to see if we have any occurences of error messages we should report (prod logs are HUGE). None of our WAS virtual machine are bigger than 1500M. A lot depends on the app and how many apps per virtual machine. Just about all of the run MQ Series as well. David mentions cluster. That requires the ND version of WAS - you probably won't get to try that out with the trial version, but is definitely the way to go when you purchase. For large apps, you may want to consider running IHS in a sep virtual machine too if you are using that. We found we gained some performance doing that.

Programmers do crazy things when they are used to having the whole machine to themselves - real life example a) Let's wake up every 2 seconds and see if such and such process is alive b) Let's run log scanning to see if we have any occurences of error messages we should report (prod logs are HUGE). We encountered that very early on. We said 'here is your problem' they made ONE code change and CPU utilization dropped by 70%. Another thing to look for is taking advantage of the build in hardware features like hipersockets to get at z/OS resources such as DB2 if they're on the same box. None of our WAS virtual machine are bigger than 1500M. A lot depends on the app and how many apps per virtual machine. Just about all of the run MQ Series as well. David mentions cluster. That requires the ND version of WAS - you probably won't get to try that out with the trial version, but is definitely the way to go when you purchase. Once you get into many instances look up Steve Wehr's paper on running WebSphere with ONE executeable directory and sharing that to each linux guest, to 1) minimize your maintenance nightmare and 2) reduce the amount of disk you needlessly would duplicate. For large apps, you may want to consider running IHS in a sep virtual machine too if you are using that. We found we gained some performance doing that. We wish we did that and eventually will do this. If you have the IHS front end in a smaller machine and it has the plug-in in it, you can direct traffic to the members of the cluster. A node of the cluster can go down, and other nodes will still do work. Right now we have our IHS on our primary node for the cluster. So we can't ever take the primary node down for maintenance without an outage. If you run IHS as it's own guest, your maintenance is invisible to the customer. Or nearly so. -J -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of David Boyes Sent: Tuesday, November 28, 2006 10:35 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] Websphere Any problems/headaches or other words of advice anyone wishs to share about Websphere on zLinux? 1) Websphere expands to fill all available resources, both human and machine.

Should I wait to install Websphere until I'm on z/VM 5.2? If you can, wait until you have 5.2 up.

Not huge, but warps your test results somewhat -- philosophically, it's always better to start as you mean to continue, and splitting things up also allows you to demonstrate the ability to construct both production and test environments on the same system. Having multiple small instances for VM to juggle is usually better than a small number of ginormous instances. It's where you want to manage the complexity (inside WAS or at the VM layer). The separate machines also give you finer control over resource utilization caps for different pieces of the app. If we start to go the route of Websphere, I, most likely will install it over a dozen times in the next year. Different variations of dasd setup and machine setup, to see which meets our needs best and also to allow me to take baby steps in implimenting new technology. Another reason for small, separate servers. You can have different virtual machine configurations in the same WAS server farm and see which one works best. You can then take the others out of the WAS cluster with only a little pain, rebuild them in the way that works best, and bring them back. Consider carefully whether you

I had WebSphere installed and in a basic, non-secured, non-clustered configurartion in less than an hour. Securing it via LDAP to RACF LDAP Backend was exceptionally challenging in version 5 but that methodology has worked goig forward in WAS 6. I expect you'll have relative ease with a WAS 6 install.

Websphere trial on zLinux?
I was looking at the IBM web pages for a trial of Websphere for zLinux. The only trials they had were for Windows and Linux (Intel). So, is there a trial for Websphere on zLinux? And if so, what are the procedures to get it? We have a project on the Open Systems side, JAVA based. Seems to be in house code. But then, it can't be much, because management is only looking for a trial. Anyway, they were looking at Websphere on 386, when they started looking at Oracle Application Server. Then things started getting bogged down in acquiring the hardware for the trial. Hardware? I have a z/890 with an IFL (running about 10% utilization) So I started bringing it up and decided to try it. My guess is that I can bring up a Linux machine (I already have some 17 of them), and install Websphere and hand it over to development, in a day. We can decide what platform the application should reside, later. If there isn't a trial available for zLinux, then I don't see how we will ever have Java applications on the mainframe (which, being Java, may be a good thing).

WebSphere PlugIn priority
Hello! I've finally installed WAS plugin for 64 bit z/linux successfully but now I've another little problem. I've configured in my plugin-cfg.xml with the Uri Name=/oto/*/ directive. I would like to serve al static elements as .sws file from my httpServer. They are called in this way http://hostname/oto/htdocs/xxx.html for example. Then I've inserted in my httpd.conf: Alias /oto/htdocs /opt/CHROOT/HTTPD-2.0.59/htdocs/atmweb/oto Directory /opt/CHROOT/HTTPD-2.0.59/htdocs/atmweb/oto AllowOverride none Order allow,deny Allow from all /Directory I've inserted these directives before the LoadModule of WAS PlugIn but it seems that WebSphere PlugIn has always priority and that the httpd.conf file would not been read in a sequential way. This configuration was ok without was plugin but using proxy pass directive in a way like this: . Alias /oto/htdocs /opt/CHROOT/HTTPD-2.0.59/htdocs/atmweb/oto Directory /opt/CHROOT/HTTPD-2.0.59/htdocs/atmweb/oto AllowOverride none Order allow,deny Allow from all /Directory ProxyPass /oto/htdocs ! ProxyPass /oto/ http://192.168.77.165:9080/oto/ ProxyPassReverse /oto/ http://192.168.77.165:9080/oto/ . In this way I could exclude /oto/htocs from the general /oto that was passed to the remote WebSphere Application Server. Is there a way to have a similar behaviour with the was plugin? I'm thing about something to add in my plugin configuration file or another directive in my httpd.conf file. Please let me know, in other ways I've to modify the context root for static elements. Thanks in advance.

It's more-or-less what we did un RHL 7.3 when /etd/fstab didn't have the appropriate description, and what I do now to loop-mount filesystem images. I very nearly nuked the FC5 systems in favour of opensuse 10.1, but I didn't really like 10.0. For the moment, I've contented myself with /tc/fstab and /mnt, the old RHL 7.3 (RHAS 2.1) way. Be aware of the security risks of using sudo on a production system. At least, you can trace usage with logs... I don't know how that will translate to zLinux when new DASD arrives... You can play with hotplug to automatically mount new storage devices on x86 Linux. Hotplug is also there with SLES9, so it could probably be possible to auto-mount newly added dasds. hotplug has left us. It's replaced with udev. RH/Fedora's implementaion, to my mind, sucks. For the desktop part, I don't think you'll run any desktop environment on a mainframe. I would not do that, personally. For applications that need graphical environment (let's say for installation as an example), I run a X11 server on my workstation and export my display from the mainframe to my workstation. Red Hat seems to expect users to run a GUI on everything, and a heaveyweight one at that. I suggest prospective users of RHEL 5 take a close look at the beta which, I think, is due out RSN. Take a close look. ps Fedora Core 3's performance on my laptop (256 Mb RAM) was poor. FC5's performance is better characterised as appalling. I removed 128, added 512 and that's fine. If anyone here does like a GUI for admin work, best take a close look at the next beta:-) -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ do not reply off-list -- 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

Frank: Generally any application which runs on Linux on x86 will compile and run on Linux on z (or Linux on POWER) with few or no changes. The exceptions are those with hardware dependencies (these are often seen in systems management type of software which gets down into the kernel). The real effort in any port is in two areas: 1) The installation tools (you would be amazed at how many Linux apps, even server apps, are dependent on a GUI install!) Nah, I wouldn't be surprised. :-) (It's Windows bad influence. g) 2) TESTING. Testing can often take as much as half the development cycle and this is pretty much repeated (or should be) on every platform. That's what I figured. Thanks for the info.

I don't know how that will translate to zLinux when new DASD arrives... 2) TESTING. Testing can often take as much as half the development cycle and this is pretty much repeated (or should be) on every platform. It depends highly on the app, but once, by way of example, Apache works on IA32 and Sparc64, there shouldn't be more to do than run the test suite pretty much to say we did it, JIC. I'd be fairly surprised if 64-bit z had new problem. 31-bit, maybe. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] Tourist pics http://portgeographe.environmentaldisasters.cds.merseine.nu/ do not reply off-list -- 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
