Is my memory under stress, I can see I am out of physical memory only near 100mb left, but as you can see I do not use eat any swap memory or having page outs.
Can any one put their inputs about this ?
I will be generous :) !!..
Regards.
Solved! Go to Solution.

Re: Memory bottleneck situation
You have an Oracle instance WSPROD with more PGA allocation.
Escalate this to ORACLE DBA , they may change dedicated server process to shared or they will tune the PGA (Process Global Area)

Re: Memory bottleneck situation
ok. I want to explore the O.S. side.
In the glance I can see that the system memory is taking 5GB is this normal ?
Can I tune this ?.
What ware the options here. More physical memorie more swap ?.
Thanks in advance !! ..

Solutiona) Your swap is at 57% and fine.
b) vsz is used to find memory leaks, not memory bottlenecks and since all your processes' are very similar and associated to oracle, I would contact the oracle DBA about the size of the oracle SGA. Note: To find a memory leak you'll need to gather 2-3 days of vsz info and observe any vsz growth.
c) 5 GB system memory is fine.
