we have been experiencing a strange memory problem with a new p550
server that is going to host a new JDE EnterpriseOne implementation.
So far, oracle & JDE are installed, and users are able to log in,

the machine shipped with 8GB memory, as specified by the JDE/Oracle
requirements... all of the neccessary AIX & application prereq.
filesets & patches are installed (java, c-compiler, etc...)..
everything looks good except that the machine is hitting 80% memory
usage with only 12 users logged in!!! when we go live in a couple of
weeks, there will be aprox. 80 users.
I understand that we will probably need to add more memory (we're
thinking of going to 24GB), but still... the system should not be
hitting 80% of 8GB with only 12 users logged in. Also, we're
averaging 29% paging.
I don't know alot about oracle/jde, and there are a lot of processes
running from both... i'm suspecting the problem may be within the app
side... but the jde implementation guys are saying they don't know
whats wrong. so.
here is some output below... does anybody have any idea what might be
causing this, or have any suggestions?
Thanks!

Hi!

Think you search on the wrong place for your problem! As far as i know oracle (think u mean the db part) isnt a "normal" process. If you start oracle *you* tell them how much memory it will use. Independent of number of user oracle use! Dont know JDE, but it sounds like it uses a java vm. Then the same problem: *you* define the amount of Memory the vm can use.
First dont worry about 29% pagingspace used (read all the posts why) and then use the oracle enterprise manager(?) to check your db buffers and check out the jconsole to look if you give the java vm enough memory.

with best regards
