Hello,

I'd like to understand... why my database get 1.2 GB even if just 1 process's running...

I used top sorting by memory and got this result \/

I'm seeing, that oninit's getting a lot of memory (892M) without process runing... What's mean this ?

the first process 913M really i'm running, but the process 892M not running.

could someone help me to understand it ?


1204 root 25 0 913M 913M 913M R 85.8 23.3 21:42 oninit

It's all right there! don't worry!

All this appear this way because Informix is a multi-thread application.

All system process access the same memory allocation (shared memory).

Each of this process are VPs (Virtual Processor) inside the informix. You can see that with command "onstat -g glo" . Will show to you each VPs and the respective PID.
