Обсуждение: Postgres on Ultrasparc

Hello folks!

I would very much like to know if anybody has any experience in running
Postgres on Linux, on a Ultrasparc machine. Any version of Postgres, any
version of the Linux Kernel, any model of Ultrasparc.

My system still halts completely when I run regression tests.

Any information ?

Thank you!

   Sure. All versions of Postgres, all linucies, all sparcs - no problem.

Host oper.med.ru - Pentium, linux, Debian 2.1. Postgres 6.4.2.
   Recently the system got major hardware problem (overheated processor and
damaged memory or motherboard). The system got down to its knees, but I
moved the disk to another system. Filesystem was slightly corrupted, but
fsck restored it, postgres started up and now it is alive and well.

Host www.indicator.ru (now closed due to lack of manager's interests).
   Pentium, linux, Redhat 5.2. Postgres 6.4.0 and 6.4.2. No problem.

Host sun.med.ru - Ultra-1, Solaris 2.5.1 with some Sunsolve patches. It is
my debugging environment, so there were all versions of Postgres - 6.3.2,
6.4, 6.4.2, 6.5.1. All went well, including regression tests.

Hi Oleg!

Thank you for your email.
Maybe I was not clear enough.

I wanted to know information about running Postgresql on Linux on a
Ultrasparc. Like this:

Postgresql on top of
|| | | | |
Linux Kernel on top of
| | | | |
Ultrasparc Hardware


So, no Linux/Intel , no Solaris/Sparc , but Linux/Sparc.

I have my Linux Kernel (2.2.5 || 2.2.12 || 2.2.13 ) running on a
Ultrasparc without any problems ( I run httpd, ftpd, nfs, samba, gnome,
lpd, etc etc, compiled a few kernels, etc) but when I run postgres and
start the regression tests... BOOM! Not even SysReq, register dump..
nothing...


Thanks anyway!
It's always good to know that Solaris will always be a solution...

   Wow, this is danger. I usually avoid Linux on non-x86. And I avoid Linux
on x86 with high load - I use FreeBSD (but not with Postgres - MySQL).
   I heared there are major problems in Linux SCSI subsystem, making it
inapropriate for high load situations. It is possible that you touched one
of these bugs.
