Subject:equivalent of /proc/meminfo in AIX
Hello All,
I'd like to quantifying large page (16mb) Memory Savings with Oracle
10gR2
(10.2.0.5) running on aix 6.1 like this test below:
In Linux we have /proc/meminfo ("PageTables") , what is the
equivalent of
/proc/meminfo in AIX? Where is the pagetables in AIX?
Thanks in advance.
