Обсуждение: Upgrading to Solaris 9
Good morning, Could you please let me know if Postgres 7.1.3 will run on Solaris 9. If it does, are you aware of any issues. Thank you for your help. Danielle Cossette

I did and had too many problems and performance issues. Solaris- PostgreSQL just doesn't gel as wel as Linux-PostgreSQL. (ouch) If PostgreSQL were to get retooled to work with threads the way it works between processes today for Solaris or if someone were to find a tweak to make the Solaris scheduler more process-centric than thread-centric (maybe via dispadmin(1)?) then I'm sure Solaris-PG would clobber Linux-PG. I still spin up 7.3.3 on our Sun V480 4CPU, 8GB, 2 internal fibre drives occasionally and our 7.3.3 on RedHat 7.3 with 2.4.20, 2 1.4GHz, 2GB memory and 2 internal U160 kills it. I've tried the many options for UFS and VxFS and EXT3 on Linux still beats it. The database I use on the Sun comes from a pg_dump on the Linux system. But, IMHO Solaris 8 or 9 in comparison to Linux on like hardware, databases, configurations and queries the latter will outperform the former every time. -= IMHO =- The short answer to your question is yes, it will run on Solaris 9.

Sounds like an opportunity for someone at Sun to fund a little research project. Any Sun/Postgresql hackers out there? Any Sun project managers lurking out there?

I had a very strong reason to make PG work well on solaris and after some digging we found that by default, PG was being compiled with no optimization on solaris. That resulted in an AMAZING speed increase - making it comprible to linux. You can get the same effect on 7.3.x by setting CFLAGS=-O2 before running configure. However, establishing connections will not get much of an increase due to solaris' amazingly slow fork(). The thread issue has been beaten to death on -HACKERS. You can also check the -performance lists for the threads I posted about this... oh a couple months ago? -- Jeff Trout <jeff@jefftrout.com> http://www.jefftrout.com/ http://www.stuarthamm.net/

I thought .org and .info were being run on postgresql/solaris? As another poster pointed out, the Solaris version was building with no optimzation, and it was kinda figured to be in the sysadmin's realm to fix that at build time. You're likely using Solaris' qsort, which was slow in the olden days but I thought it had been sped up recently. If it's been fixed, no worries, as I'm pretty sure Solaris 9 has a qsort that sorts fast with many identical keys. Either way, upgrading to 7.3.4 or 7.4RC2 (for testing, in a couple weeks release...) should provide a very noticable speed increase over 7.1 due to many improvements made since that version. The upgrade to 7.4 might be easier than the upgrade to 7.3 followed by 7.4, as 7.4's pg_dump and pd_dumpall are version aware and can dump a live 7.1.3 database. So, if you wanna try it, just build a test server and: pgsql7.4rc2: pg_dumpall -h production_machine_running_7.1.3 |psql -h testbox_running_7.4.rc2 and see what happens.

Windows is worse ;-)

They are. I'd happily dump the Solaris use overboard, however, if it
weren't for all the nifty hardware support it give us. It is
dog-slow for handling large numbers of processes. We get around that
by throwing hardware at the problem.

I've run 7.1, 7.2 and 7.3 on Solaris 8 x86 and Solaris 9 x86. 7.1 install, config, run was nearly 100% hands-off. 7.3 takes setting LD_LIBRARY_PATH to point to /usr/local/lib. They've run fine for 3+ years ... except I had always allocated a trivial amount of shared memory to Postgres. A few months back, I decided to increase the shmmin/shmmax parameters to something a bit more usable and the OS promptly kernel panic'd upon bootup. It took a few tries to get values that worked. But this week, Solaris just went nuts and kept kernel panicing until I dropped shared memory to next to nothing -- which set Postgres performance back to be unusable. I blew the OS away, installed Linux and everything runs fine. Actually better than fine; better performance due to better drivers (especially for ATA hard drives), better disk cache management, lower memory footprint, etc. I had already switched to Linux on one server due to a non-working LSI 32320-R driver and this shared memory problem has pretty much cemented our plans to move off Solaris.

One might choose to use Solaris for a number of reasons _other_ than it being the fastest platform for PostgreSQL: - If some applications are written in Java, Sun might be chosen as the hardware vendor because "Java works there best." - If you're buying hardware in bulk, it may be a better deal to have to throw extra money at the DB server if you saved money on the other boxes. - Local familiarity might be worth something; better the devil you know than ones you don't. - Reprovisioned hardware from another project is cheaper than starting afresh. I wouldn't warrant that any of those are necessarily applicable in this particular case, but "which platform runs PG fastest" could readily get pushed lower on the list by these sorts of factors... -- let name="cbbrowne" and tld="ntlug.org" in String.concat "@" [name;tld];; http://www.ntlug.org/~cbbrowne/postgresql.html "How much more helpful could I be than to provide you with the appropriate e-mail address?
