Home -> Community -> Mailing Lists -> Oracle-L -> RE: Solaris /etc/system values for Oracle8i
Just wanted to jump in a bit here. I have 4 oracle instances running on a
solaris box with 2GB of RAM. My available memory hovers at a little more
than 1 GB free. Swap size isn't really a factor, unless you are actively
swapping, which we are not. Now granted the largest of these instances has
a SGA footprint of about 200MB. While we are not talking about large
databases, I think I could easily drop 4 more smallish DBs out there. Now I
admit, that if I needed to do this this, I would also request additional
memory, but that is just my nature, not a real requirement. oh and since
you did ask about swap size in Tanel's case, our swap slice is 2GB we rarely
use more than 500MB of swap.

How large is the swap file? For Oracle usage, maximum memory settings in the /etc/system file are based on total memory available, or REAL memory. This would be physical memory + swap file space (virtual memory). So, with 1GB of physical memory, and an equal amount or more of swap space, you could run it the way you have configured it.

Please respond
to ORACLE-L
Yep, I have development and even small production 8i instances which take only about 100MB of memory (SGA, listener, dispatcher, shared servers).
