How much RAM allocated to free box?

[khalidaaa]

Hi All,

I just got a question from our DBA saying that when he stopped oracle 10g application which was running on an AIX box, the computational memory was 30%.

So his question was why it is 30% while nothing is using the system?

When the machine was rebooted, that RAM was 12% only.

My guess is that this precentage is just some leftover program text files that would not be there (swapped out) if that memory is needed for other processes.

Could you please clarify this?

Thanks.

Regards,
Khalid

If your running any java stuff, I can almost guarantee you have a memory leak. I've have a couple of scripts if you need to check.

Thanks Mike for your comments.

Yes, you are right, Oracle 10g application uses Java.

Please help me with those scripts!

But i'm wondering how come this happen (memory leak) while the application is down when i first viewed the memory!?!
