Обсуждение: postgres on Solaris 10 with ZFS

Hi All,

I have solaris 10 update5 sunfire X4240 with 32GB RAM and ZFS system.I am having problem while configuring below parameters especially how shmmni works ---

 1) shmmax
 2) shmmni
 3) arc_max
 4) shared_buffers

Since, it's a dedicated server i want to utilize all resources.As of now i have set parameters as below --

 1) shmmax -- 16GB ( size of single shared memory segment)
 2) shmmni  -- Default 100
 3) arc_max  -- 26 GB
 4) shared_buffers -- 2 GB
 5) effective_cache_size -- 5GB

Also, would it be possible if i can have more memory segment for same postgesql.If yes How ?

Please help.

Regards,
