Default Automatic Memory Management on AIX and Solaris - 11-07-2011 , 01:24 AM






Could someone please point to documentation, Metalink note, blog post
etc that explains how
Automatic Memory Management (AMM - 11g feature) is implemented on AIX
and Solaris?
There are many documents for Linux explaining that with AMM enabled
instead of using normal
shared memory segment (visible with "ipcs") Oracle uses "/dev/shm".
However I couldn't find any info on AIX/Solaris. As far as I could see
Oracle still creates normal
shared memory segment visible with "ipcs". Isn't it static in size?

A very good write-up for AIX can be found here:

Check the posts tagged with "memory" - it also covers the AMM variant
on AIX extensively in several of the posts.

Hope this helps,
