Re: GUI development tools
Hi John, Didn't mean to imply that we would be doing development on the Z box, we won't. Currently, we run XML code development under Eclipse on the PC and then port the code up to the Z. Kevin -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of John Summerfield Sent: Saturday, November 17, 2007 1:39 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: GUI development tools Evans, Kevin R wrote: I would like some feedback on development tools, let me describe the environment first Our existing CICS system uses what we call dot delimited messages. These all arrive over point to point encrypted communications lines into what we call CORs (kinda sorta like TORs but without terminals). The COR code either does some routing or passes the messages to the AORs. The AORs process the message and send the result to the COR who then send it back to the original requester. The XML system runs under zVM as a Linux guest (software here is written in C) which we refer to as an XOR (XML owning region). Its job is to translate the inbound XML message back to dot-delimited format and push the message into the COR. The existing system runs as normal (message into the AOR and get the response etc). The COR then sends the response to the XOR who translates the dot delimited response back to XML and sends the response to the originating end user. The GUI software I am talking about developing is to control the Linux guest where we have configuration files written in XML that we want to change from the outside world while the guest software is running. We also log all messages in and out and want to write some GUI software to search these logs etc. The custom GUI software can then be used for those searches/configuration changes etc. I'm not sure I'm keen on developing/running GUI software actually on your very expensive Zed. An idea I like is to run the GUI on one system (eg your Intellish desktop/laptop) and the commands on the server (Zed in this case).. This kind of implementation would be well-suited to developing on the peecee, you would only need to compile on the Zed for final testing. The final choice as to where to run the actual GUI need not be made until implementation, and would be easily changed when you find running GUIs on the Zed's not that good an idea. Apple (OS X xserv) has a fairy sold set of commandline tools that can set and interrogate settings. While they can be used from the standard shell, I suspect their purpose is to separate the GUI from the configuration so the GUI can be run on one machine (my laptop) and the commands on the server, I don't know what communications protocol it uses, but shell commands piped through ssh would do. If you use qt libraries, then you have the option of also building the GUI part for Windows. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 Please 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 -- 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: Software licensing cost savings
Don't forget Marcy Cortes's work with Linux guests under z/VM at Wells Fargo. She gave an excellent presentation at the latest zExpo in San Antonio back in September on what's happening at Wells Fargo regarding production Linux deployment and acceptance there. It's not (yet?) available from the Linux on VM web site, but I can send a copy to anyone that wants one. Novel is also hosting an on-demand webcast on SUSE Linux Enterprise Server for System z, that might address some actual customer experiences.

I just had a meeting yesterday with a client who is unable to get any more power for their data center. (The utility refuses to sell it to them.) So, they're looking at migrating a bunch of midrange boxes to Linux on System z. -snip- From what I've read it seems that some software vendors, like IBM and possibly Oracle are charging the same amount per engine as they are per distributed cpu. As you say, a number of ISVs are treating Linux on System z as distributed workload and pricing it per engine. Almost all of IBM's middleware products are like that, for example, as well as Oracle. The problem with Oracle is that they haven't made a lot of their applications available so far. Some of them, but not even a majority of them (last I checked). Since we can run several Linux instances on one engine, there are clearly cost savings there. Basically do you guys know of any more examples ? Nationwide Insurance has been very visible at SHARE and System z Expo, talking about their savings. First National Bank of Omaha. Citigroup running DB2 was mentioned in an Information Week article a whle back. What vendors / software are people targeting to consolidate on the mainframe do to the software licensing savings ? I'm not yet really happy with the page at http://www.novell.com/partners/ibm/mainframe/success.html but you can look there to get an idea what people have been doing.

Stupid newbie question re: Installing SP1 to SLES10 on z/890
We are in the midst of installing our first production system under SLES10, under z/VM on a z/890. My question is, how do install SP1? I have a virtual machine that has the repository of all the files necessary to install both SLES9 and SLES10. I recently downloaded the iso image of the DVD for the SLES10 SP1. I have used this to install additional optional software on the target system, but I've never installed a full-blown service pack on Linux. Is there a simple way to mount the iso image, fire up Yast on the target, tell it to do the update and stand back? Or, must I go though each installed option in Yast and update each one individually?

The SLES10 SP1 DVD is a complete installation tree, in and of itself. Given that, probably the easiest way to update your systems is by IPLing them from the starter files on the SP1 media, pointing the installer to the SP1 installation tree, and then doing an update, rather than a fresh install. If you want to do it while the system is up and running, it's much more of a pain in the $ANATOMICAL_PART. If you want to upgrade a SLES9 system to SLES10 or SLES10 SP1, you have to do it via IPLing from the SLES10[SP1] starter files. You can't do it from a running system. Which ever way you go, you'll need to rummage through your system afterwards, and make sure things are still configured the way you want them. I've seen cases where stuff got changed, and I had to re-do them. Also, look for *.rmpnew files. Those will be new versions of configuration files that didn't get moved into place because you updated the ones on the running system. Also look for *.rpmsave files. I'm not sure what criteria gets used to create those, but they're copies of configuration files that were replaced, but saved.
