As you can see, the display is showing ASCII interpretations of the hex code.
This is assembled as 390.
Is there any way I can get the display area to show me the EBCDIC translation?

Mark, from one of the developers of ooRexx From the segmentation fault data, it looks like you're compiling this in 64-bit mode. This code has lots of type cleanliness issues that preclude 64-bit execution. You're going to need to force this to compile/run using 32-bit addressing.

Re: Oracle instances
I'm now hearing requirements that the application will be on its own, dedicated, instance. We are trying to keep away from that. Why? This is actually a Good Thing in most cases. It also allows you to individually throttle badly behaved applications when necessary, and makes accounting for rotten code a lot easier to do. Or course, if the database structure and/or the queries are poorly designed, then having most of the database in the SGA, can hide a lot of performance problems. G Most Oracle apps are poorly designed or tuned, or both. Isolating each app into separate servers gives you demonstratable proof of which part is going bad. Reduces finger-pointing by significant margin -- although keep in mind that it also exposes who's been hiding badly designed apps in the hardware budget, and those people won't be happy. So, who has some guesses on valid reasons for having one application per Oracle instance. Again, a dozen or so users, the tables occupying about 1-2 GB in total. There's no licensing issue to do it (in fact, that's a good factor to feed into the cost case). Most cases, the virtual machines don't need to be as big as they were before, so you can squeeze the requirements significantly (subject to your performance monitor results), and you get the simplicity of managing one app per server without competing resource demands. You have to pick your battles. This is one where it's not worth fighting, and you get benefits by giving in. Give it to them. -- 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: Oracle instances

Re: Oracle instances
Before I asked for clarification, I was thinking pretty much the same thing David said... Stop whining and get to work! But, seriously aside from the fact that there is the possibility for consolidation (you have to fight that fight, we can't help you there)... I would strongly suggest you read and consider implementing the XIP filesystem for Oracle as described in the redbook. With 50 Oracle instances the potential for virtual storage savings is pretty grand.

We just can't have that many users. Currently we have 204 PC type database servers and we only have a few thousand PCs. I figure it comes down to 20-30 possible users per database with the very fast majority of them, occasional users. First, the 2G size is *way* too big to start. Also, with that few users, the server images are likely to go idle fairly often, and Linux has become much better behaved about releasing resources when not needed. So, I have been planning for about 5-7 production servers such as: 1. First shift server (most City functions end at 5 PM) 2. 6 AM to midnight server 3. Near high availability 4. Convention Center (their usage and uptime requirements based on the current conventions) 5. Courts system perhaps a couple other weird ones Plus their test systems, development systems. Think about it in terms of time spent tracking down problems. 1 app per server means you know exactly where the problem is if someone calls in a ticket. Your time - and time out of service - is much, much more expensive than more hardware. Also think about what it would take to reconstruct test servers, etc. Having separate servers for each purpose allows you to easily create/destroy instances, clone from dev to test, etc in a controlled way. That's a lot harder to do if you're sharing guests with multiple apps. 1. Very high utilization along with performance requirements 2. Political 3. Some idiot designed things that every user needs DBA authority, hence would have access to all other applications tables. #2 and #3 are the dominant force in most distributed applications. It's the toddler view of the world -- I have it, therefore it's mine. Mine, mine, mine. 8-) But, seriously, think about the time you'd need to diagnose stuff, or sort out how to combine applications into smaller #s of servers. Is it really worth the amount of administrative overhead you'll undertake to get a fairly small savings in resources? It's a lot harder over time to maintain shared images, especially if you don't have ways to coerce programmers to write maintainable systems. People are also a lot more expensive than hardware, and in the combined scenario you need more skilled people, which are even harder to find. In large mainframe shops (not that we are one of them), I've only seen a few database servers running to support all their applications (outside of the PC servers). Most of those large mainframe environments also have the benefit of control over the applications development or deployment that you're not likely to have if you're using apps brought over from the distributed environment. You might, but it's a rare occurrence, and that's a LOT harder battle to fight than just giving them separate instances and showing an immediate ROI improvement on license count. Rich's comment on XIP is a good one -- that's a winner, and you can still give them what they want w/o wasting resources, but the other parts are kind of penny-wise/pound-foolish. This is a battle you don't have to fight; think of it as a quicker way to get machine upgrades...8-). -- db -- 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

Hmm. Where do I start. Sorry this has been frustrating and unexpected. We began with a straight upgrade path with a guest pointed at a SLES10 NFS installation source. After lots of attempts we installed the starter system (which is nice) It allows you to boot the existing guest (sles9 spX) you would like to upgrade then execute a startup script which leads to having a SLES10 starter system with the old SLES9 DISK/RPMs, etc. Then you are able to (or alleged to be able to ) simply execute YAST/System update and the update would continue with a proposal and all that. We have been at it for weeks. Bottom line is the disks/mount points are NOT recognized. I'm almost ready to bag it up and do straight installs but no_can_do with the number of guests and amount of customization of each.

Re: SLES 10 SYSTEM UPGRADE and Starter SYSTEM
Me too. Interested in upgrading my many sles9's to sles 10 without doing a complete re-build. If anyone has anything to share about the sles 10 upgrade process please post. I haven't been able to make the upgrade function work between major releases at all, and don't really trust it anyway.

Re: Oracle instances: resolved
Wasted a hour in a meeting, but for them, it was productive (which is a positive thing). The consultant normally deals with SQL Server. He has used Oracle 10g on a PC. In that world, Server, Database and Instance are all the same thing, and I guess in the normal SQL Server world, that can't be separated or isn't normally separated. Finally, we brought up Oracle OEM to view our structure. All he wanted was his own Schema with its own tablespace, about 100 MB now, extending to 500 MB in the future. Wanted to create a dozen users. Wanted to create and load some tables. 10 minutes of some mouse clicking...done. The pilot starts tomorrow. Fun times...

Re: Oracle instances
Never it be said that I haven't (and will) go off on tangents that may or may not be productive... And the advice to just run one application per database, is an easy one..it is simpler. For those that gave advice...do you run Oracle on zLinux? What rate of resource consumption does your idle Oracle images consume? I currently have 4 images running. When they are completely idle, the IFL runs at 12%. That is 3% per idle Oracle image. When I take down the 4 images, we idle under 1%. That would seem to me that about 30 idling Oracle images will drive an IFL (z/890 flavor of IFL) near capacity. Hence running lots of images, just because you can, may not be a good choice. And maintaining 30 copies, disk, backups, etc, just to avoid performance tuning... I don't know. Is the economics such that, that is better? I think I could argue the issue either way, until we start loading this up. And we have Oracle Enterprise Manager running which does some decent performance monitoring. That should aid in performance problems. VM shows that an idle Oracle 10g server, with OEM running, also does about 10 I/O per second. A lot of this could be things I caused. I took the development servers down in memory size to what would still come up. That is 146 MB for the SGA and 16 MB for the PGA, running in a 500 MB image (of course with vdisk). FYI, at 400MB, the image didn't swap until hours after a boot. That is when the SGA was finally, entirely used and wrapped around. Then, we would swap at a rate of few pages a second. I didn't want an idling image swapping, so I bumped it up to 500 MB. As for production serversI don't know yet. I haven't been given requirements on what anyone expects. Anyway, sometime this week, we will have a discussion on why they want a dedicated Oracle image. And since this application will go into production in May, I hope to get some metrics so I can provide a production server that can meet expectations. I expect, under 20 users. I expect under 1,000 queries a day. I expect the overhead of Oracle and OEM, to exceed the resources used for those 1,000 queries. I expect this application, where it is important, is lightly used, in the grand scheme of things. G As far as memory saving techniques (such as XIP). I'm under the impression, and hoping for, that it will be fairly easy to retrofit XIP in Linux later on, when I can get some bang for the buck.

Re: SLES 10 SYSTEM UPGRADE and Starter SYSTEM
Gerard, We are at SLES9 SP3 and have upgraded over 30 systems to SLES10 SP1. It helps to install a SLES10SP1 system from scratch before you try to upgrade. Our shop runs SAP. SAP requires changes to files like /etc/services. Some of those files get overlaid. One of the tasks before starting the upgrade is to identify what all the upgrade is going to overlay that you have changed. We started out with the redbook, so we copy our SLES10 SP1 CDs to our NFS server. We updated our parmfile to point to the NFS server. Then we execute the REXX to boot off of the SLES10 CDs using the parmfile. We then pick the language, then configure the disk drives, then when it ask you what installation mode to use, pick update. The upgrade overlays certain files like /etc/services, so we have to fixup the /etc/services file. We are also an SAP shop, so we have to fix things so that SAP will start up after the upgrade. Our document with our procedures is about 28 pages (with lots of pictures). One thing I did check was the release notes for SLES10. Supported Update Paths Updates from SLES 9 to SLES 10 are supported starting from one of the following bases: * SLES 9 GA * SLES 9 SP3 * SLES 9 SP3 plus the latest patches from the maintenance Web SLES9 SP2 is not listed as supported.

Re: Oracle instances
I can't really tell, but I can guess. TOP only shows a bunch of oracle processes, but... At least one of them is the Oracle Enterprise Manager, with does performance and such. Another one is the log process. It closes a 10MB log file about every 50 minutes under idle conditions. Much more frequent when active. And Oracle OEM has its own scheduler which pops to see if it needs to do anything. I can run without OEM, and get rid of much of the overhead. But then when a bad query comes along, I have no way of knowing, unless it gets to the point of users complaining to the help desk. With it, I look at the historic charts, see nothing, and do something else.
