On a HP DL580 with 12 GB of RAM ( Intel Xeon - 32 bits), We are running the following config in a demo environment without any major incidents. * PAE is enabled at the hardware level ( probably not relevant for EM64T ) and you use a big-smp kernel (2.6.5-7.257-bigsmp) * You increase /proc/sys/kernel/shmmax to something like 4294967295 and /proc/sys/kernel/shmall to something like 2097152 * You use indirect buffers && "old style memory" allocation in your init.ora use_indirect_data_buffers=TRUE ( Big performance hit I guess) db_block_buffers=445000 db_block_size=8192 We can open a database till 6 GB of SGA. (our SGA is 4.3 GB right now in this environment though).

Box can run up to 12 GB. Up to what main memory size is it possible to run 32 bit Oracle and 32bit SLES? We tried 64 bit Oracle and SLES but had 20% performance loss. Anybody running > 4GB with 32 bit? We do not plan to use more than 1GB for Oracle SGA. regards, Toni -- +--------------------------------------------------------------------+ | Anton Dischner, Unix admin, Oracle-DBA Phone: +49 89 70953202| | Institut fuer Klinische Chemie Fax : +49 89 70958888| | Klinikum Grosshadern Home : +49 89 69708766| | Ludwig Maximilians Universitaet Muenchen Mobil: +49 172 8388880| | 81366 Muenchen Germany | | Marchioninistr. 15 dischner at med.uni-muenchen.de| +--------------------------------------------------------------------+ -- To unsubscribe, email: [email protected] For additional commands, email: [email protected] Please see http://www.suse.com/oracle/ before posting -- To unsubscribe, email: [email protected] For additional commands, email: [email protected] Please see http://www.suse.com/oracle/ before posting
