Dear Netlanders and IBM unix guru(s),
I'm working on configuring some applications (using X and our dbms) on an AIX
box with a number of X terminals, but our requirements (in terms of system
resources:- memory & swap) are spiraling. What I'm missing is details about how
AIX is using these resources and ways of monitoring that usage.
Can anyone help me with this? Here come detailed questions...
1. It's rumoured that AIX divides it's swap into 3 sections : one for data, one
for text segments, one for "Client paging".
- Is the boundary between these sections dynamic ?
- How do I see/influence these boundaries ?
- How can I monitor the "client paging" (apparently the X terminals can page
to the UNIX. Is this by magic ? Can I watch it happen ?
2. Are their tools I can use to watch how the memory & swap are divided amongst
the processes ?
- "ps vax" gives me numbers with column headers, but I dont know how they're
calculated. If text segs are shared, (or libs) are they counted twice for
RSS, SIZE etc ?
- How can I examine the way the swap is used ?
- Does anyone have desciptions of how AIX is allotting memory ?
- Does anyone have desciptions of how X stations allotcate memory ?
3. Are their any special bugs/problems on a X station using an AIX as a
server ?
I'd be grateful for any replies (to steves@troll.ingres.COM ) and I'll
roll up the responses and post them back.
Cheers, Steve Sheil.
