Solaris 2.6 SHMMAX setting for Oracle 8.0.5
Posted on 2000-04-20
Server Platform: Sun Solaris 2.6
Oracle version: 7.3.4
Other Install: Context Cartridge 2.3.4
Physical Memory: .5 GB
Swap Space: 1 GB
We have run into an issue with the default SHMMAX settings suggested by Oracle documentation. Oracle documentation suggested that we have a 4GB SHMMAX setting, but when we used that setting, it seemed that swap space was being taken for the SGA.
It has been suggested to us that we use an SHMMAX setting that is the same as physical memory. In our case, it would be .5 GB.
My question is for those who have dealt with this situation...
Is it better to set the SHMMAX setting to the amount of physical memory? If so, then why does Oracle documentation state it differently? May we experience problems because the SHMMAX is set so low?
