installing Oracle on Debian AMD64
Dear People, I am (unfortunately) trying to install Oracle Database 10g on Debian AMD64. I know this is routinely done on i386, but I'm having some problems. The errors I get appear below, when I try to bring up the installer screen (using ./runInstaller), which I believe uses Java. I have found discussions of this problems in Ubuntu forums, but nothing for Debian. Eg. http://ubuntuforums.org/showthread.php?t=40392highlight=locale+set+CX I installed the 64 bit versions of Java 1.5 using javapackage. ii sun-j2sdk1.5 1.5.0+update05 Java(TM) 2 SDK, Standard Edition, Sun Micros One significant difference between Ubuntu and Debian is that 64 bit Ubuntu, like other commercial distributions, has some 32 bit libraries included in it, including the X one. All the discussions I've found pertaining to Ubuntu reference the 32 bit X libraries in some way. I'm not clear what the problem here is. Can anyone clarify, and/or suggest a workaround? This is probably wishful thinking, but is it possible that this error arises because I am doing X forwarding from a 64 bit machine to a 32 bit machine over ssh, and would go away at the console? At the moment I don't have access to the machine in question, but will try then when I do. As a fallback position, does anyone know whether installing a 32 version of Oracle Database 10g in a chroot in a 64 bit system would be workable?

What is the other half being used for? The kernel is taking 2Gb of address space, not memory. You can have multiple applications using 2Gb each. An application can only have 2Gb allocated to it. The kernel uses its space for PCI devices etc. Hmm. Thanks, that's very informative. That makes it much less likely we will be switching back to 32 bit. One option is to run a 64 system with a 32 bit chroot. I think there should be no problem with this. However, I was wondering if people has any idea whether it was possible to use the regular /home from inside the chroot. Also, is it possible to have X forwarding working from inside the chroot (assuming one is logging into the regular system)? Yes and yes. You can use a bind mount to make /home available in the chroot. Yes, I thought that might be possible. X works if you keep $DISPLAY and have access to $HOME/.Xauthority. If you use dchroot, then the -d switch keeps the environment and X just works. Can you point me to a good reference to this kind of stuff? There is lots of info on the net, but I don't know what is the best. One more question is whether there is any problem sharing a home directory between a 32 and 64 bit Debian system on an amd64 (assuming one is dual-booting)?

perspectives on 32 bit vs 64 bit
Dear People, I have an Opteron server, on which I am running the AMD64 Debian port. For various reasons, I'm contemplating going back to 32 bit. The major reason is that aside from the packages in the AMD64 Debian archive, it is not always easy to find Debian packages for AMD64, since i386 is still very much the default. Also, not all software compiles with AMD64. I am aware that 64 bit computing has considerable advantages as well. I'm looking for perspectives from people who have experience with both, and what their feelings about this are. Specifically, I was looking for clarifications about memory issues. I have looked at stuff on the web, but am still confused. What is the 4 Gig limit for 32 bit processors that people talk about? Does this mean that each process/thread can only get a limit of 4 Gig? Is there any workaround for this? What are the other limits? I read elsewhere that a 32 bit Linux system has an effective limit of 16 Gig usable memory total. Thoughts appreciated.

strange error messages on bootup
Hi, I just did a new installation on a server with dual Opterons and 8 250 G disks using RAID 10, with a total of 1 Tb usable storage space. I can give more specs detailed if necessary. I'm seeing lots of lines like the following scroll by at bootup scsi: host 4 channel 0 id 0 lun 0x642e6b6f3a202f6c has a LUN larger than currently supported.

This is with both of the stock Debian kernels kernel-image-2.6.8-11-amd64-generic and kernel-image-2.6.8-11-amd64-k8. The machine seems to be working completely normally as far as I can tell.

On Thu, 21 Jul 2005, Lennart Sorensen wrote: One dual core opteron compared to two single core opterons: Each opteron has a memory controller built in that does dual channel memory support. A dual core opteron still only has one memory controller and hypertransport to the chipset. The two cores share it, so two single cores have theoretically twice the memory bandwidth of a single dual core. Of course they also require a dual socket board rather than a single socket board, and you could put two dual core opterons in a dual board and get to use 4 cores total without having to pay for a much more expensive 4 socket board. Two cores in one package may on the other hand have faster access to each other's caches which may be an advantage in some situations, while in others sharing the memory bandwidth could hurt. At the same time the dual core would always have it's memory local, while two single cores half the ram is likely connected to the other cpu so access would have a 1 cycle penalty for access. A decent OS would try to make sure applications are running on the cpu whos ram they are currently in whenever possible. Hi, Thanks for the information.

comments about hardware
Dear People, My bioinformatics research group at Duke is buying a server, which will mostly be used as a server, particularly for web based services. The idea here is that a user will submit a request for some bioinformatics calculation via a web interface (often using Python or R or similar), the server does the calculation, and returns it as a web page. None of us are experts about recent hardware, so would appreciate any feedback about hardware specs. The following quote is from Monarch Computers. We plan to run Linux on this. It has not yet been decided yet what, but it seems most likely that it will be either some Red Hat variant (Fedora Core, CentOS), or Debian (possibly Ubuntu). Ok, so here are some specific questions. 1) Dual core Opterons first came on the market in April. The sales rep said that AMD Dual Core Opterons did not work with Fedora Core. Since they only install Fedora and SuSE, they had no info about Debian. Any idea what the status is here? How well are they supported, and how stably do they run under Linux? Also, I was told that a dual core Opteron, which is somewhat more than twice the cost two regular Opterons of similar speed, is not equivalent to two regular Opterons in functionality. Can anyone point me to information about this, or offer a comment? 2) I'm wondering if the listed motherboard is the best choice. I see it listed in http://alioth.debian.org/docman/view.php/30192/27/mainboards.html We are looking for the motherboard that has the least known issues. Preferably something that will work right out of the box. Google found me http://lists.debian.org/debian-amd64/2004/09/msg00443.html but would be interested in other reports. The specs are here http://www.tyan.com/products/html/thunderk8spro_spec.html It looks like both the graphics card and the ethernet cards are onboard. Looks like the graphics card is ATI RAGE XL PCI, which supposedly works with the 'ati' driver. Is this under XFree 4.3? The ethernet cards are an Intel Ethernet Pro 100, which supposedly works with the e100 driver and a Gigabit Broadcom which works with the tg3 driver. There seem to be two cards here. Is that correct? I'm kinda allergic to onboard cards. They are often trouble. Has anyone had experience with Debian Sarge installation with this? Does anyone have a board to suggest that they prefer to this? 3) I'm also wondering if peple have thoughts about the RAID setup. The rep said he would be using RAID 1, but I see RAID 10 is listed. I'll have to check on this. Anyway, assuming this corresponds to http://en.wikipedia.org/wiki/Redundant_array_of_independent_disks#RAID_10 with each RAID 1 set as two drives, and 4 RAID 1 sets striped together, does this seem reasonable?

Do you have any personal experience in using this? I'm concerned about stability issues. Also, would there not be some practical difficulty in getting this installed, seeing as with an earlier kernel it probably won't boot, and the official Debian installers all use 2.6.8?
