MySQL Server Hardware
by joel d 27 Apr '07

27 Apr '07

I'll take a stab at this one. At work our MySQL database contains product info and indexing data. The reasoning for designing and taking this outside of the business application is the business app. doesn't do web communication well (limited functionality and at times spotty app reliability). The business app doesn't matter (and I bet no one has heard of it anyway). Our design spec was hearty at a HP DL 385 with dual AMD CPUs (dual core I think) 5GB of RAM and around 7 internal 15k drives in RAID 5. Every bit of hardware is HP/Compaq. Without starting a distro thread we picked Red Hat AS V4. This combo has served us well and I am sure *many* other distros would do this at least as well. For us our biggest corporate reason for R.H. was most of our application vendors suported R.H in one way or another (a vote for getting good at only one skillset/distro). During application & DB development we considered uptime and ordered a second identical box mainly for a total server failure of any sort. They run very well as MySQL master and slave. In the year it has been up we are very happy with this combination. Feel free to forward any specific questions (direct or via the group). Hope this helps, Joel ============================= Date: Tue, 24 Apr 2007 14:59:55 -0400 From: "John Westcott, IV" <John.Westcott(a)tufts.edu> Subject: [Wlug] MySQL Server Hardware To: wlug(a)mail.wlug.org Message-ID: <20070424145955.3hftuclhdwg0ck4s(a)webmail.tufts.edu> Content-Type: text/plain; charset=ISO-8859-1; format="flowed" Howdy All, I work in a place that has traditionally used Sun Sparc hardware running Solaris to host a production MySQL environment. We are going to be replacing our database servers this year and I am trying to determine if I want to maintain the norm or if I want to try to change. I am interested to see what other people use for hardware/OS for a production MySQL installation that requires a high amount of uptime. Thanks in advance for any replies. -John Westcott

Hauppauge 500 woes
by Mike 22 Apr '07

22 Apr '07

I've been working on setting up a MythTV box with a Hauppauge 500. The reception I am getting is a bit grainy. I read that it could be the firmware, too high of a signal, or too low of a signal. I took care of the firmware last night by following the directions on their wiki. The picture is still a bit grainy. Before I go out an buy a signal booster I was wondering if anyone had any ideas or experience with the 500. ~Mike -- They who would give up an essential liberty for temporary security, deserve neither liberty or security --Ben Franklin

New ULTRA1 - one step forward, two steps backward....
by ken jones 20 Apr '07

20 Apr '07

Folks, When the box failed to boot, you might remember, it complained that the kernel was "too old". I remade the box using the newer kernel 2.6.20. I apparently configured the correct silo.conf (there are five of them in there when using the livecd). It looked like it was going to BOOT!! :-) See below..... Trouble is this is as far as it got. I printed and used as reference the Gentoo Linux 2006.1 SPARC Handbook, the Using UTF08 with Gentoo document and the Gentoo Upgrading Guide. Nevertheless I had a very difficult time with manual configuration of the kernel. I had not the faintest idea which modules I could ignore and which I needed to modularize Question: is there a log somewhere? I did emerge syslog-ng. Another question: Where is the detailed documentation on all the modules? Final question: How do I get a hint at what I did wrong?

3D support
by dulsi＠identicalsoftware.com 19 Apr '07

19 Apr '07

I started looking for a new laptop. I'd like one that can play Neverwinter Nights with open source drivers. Obviously that is a problem since 3D support without the binary drivers is not great. I figured since the game is rather old a good cpu (or two for the duo) and a well supported open source driver (I remember hearing Intel having released an open source driver) that it could run reasonably. I asked some linux laptop vendors and everyone told me that I would need the binary drivers. Are they right and we still can't run a 5 year old game? Am I stuck waiting for nouveau?

I am getting discouraged with Gentoo on ULTRA1
by ken jones 16 Apr '07

16 Apr '07

For those of you who are kind enough to care....sigh. On my Ultra1 I succeeded in following the directions in <http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml> to the letter, or so I thought. I "emerge'd" successfully. I compiled successfully. I chroot'd successfully. I removed the CD from its drive. I boot'd and I got the following. yadda yadda yadda.... VFs: Mounted root(ext3 filesystem) readonly Mounted devfs on /dev FATAL: kernel too old Unimplemented SPARC system call 188 Kernel panic: Attempted to kill init! Press Li-A to return to the boot prom I compiled kernel-2.4.34. I chose 2.4 over 2.6 because the handbook hinted I should.. Now I do not even know what questions to ask myself. I checked Google on the "kernel too old" message and the "Attempted to kill" message. I could not understand the few matches that it found. My bet is that I need bigger SCSI hard drives. I'll also be glad to shut up if this is getting boring. Ken

New ULTRA1 success - almost
by ken jones 15 Apr '07

15 Apr '07

I have succeeded in compiling Gentoo Linux-2.4.34-sparc kernel on my new ULTRA1. This machine-toy has kept me off the streets and out of trouble for the last couple days. (The weather has been cooperative toward the same end.) I have a question. The Gentoo instructions <http://www.gentoo.org/doc/en/handbook/handbook-sparc.xml?part=1&chap=7#comp…> tell me that if my kernel is too big that it might not boot. "If the (uncompressed) size is bigger than 2.5 MB (for Sparc32) or 3.5 MB (for Sparc64), reconfigure your kernel until it doesn't exceed these limits. One way of accomplishing this is by having most kernel drivers compiled as modules. Ignoring this can lead to a non-booting kernel." My kernel after a strip command is still 3.7M. -----------snip from command line after a strip command----------- (chroot) livecd linux # strip -R .comment -R .note vmlinux (chroot) livecd linux # ls -lh vmlinux -rwxr-xr-x 1 root root 3.7M Apr 13 06:03 vmlinux --------------end snip---------------- Should I take this warning seriously? How do I figure out which drivers to deselect from menuconfig? lspci gives me no response. I am not sure what is in my machine. Ken Jones
