Memory Sizing for oracle and Grid users
I have a two node RAC environment. The servers are identical. We installed the oracle software with the user oracle and the grid software with the user grid. I have this much available memory on each server:
$prtconf|grep -i mem
Memory size: 130560 Megabytes
memory (driver not attached)
virtual-memory (driver not attached)
We are using Oracle Clusterware and ASM, which is owned by the user grid. 32G has been allocated to the user oracle and 32G has been allocated to the user grid
/etc/project shows the following:
$more /etc/project
system:0::::
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
oracle:100::::process.max-file-descriptor=(basic,1024,deny);process.max-sem-nsems=(privileged,4096,deny);process.max-sem-ops=(privileged,4096,deny);project.max-msg-id
$prtconf|grep -i mem
Memory size: 130560 Megabytes
