Small question

[Charlie]

Is it possible to have java check to see how much memory a particular
program is chewing? Preferably every second.


The program whose memory needs to be checked is a windows NT based program
suspected to have a memeory leak!!


A speedy reply would be appreciated


Cheers Charlie

Hi,
I am not sure. Can you please try the following in the code

Runtime.getRuntime().freeMemory() at the beginning and at the end of the
method. It will give you the memory used for that method. Please let me know
whether it is OK or not..

It seems to me that Java isn't to relevent to this problem.If its an NT program
the why not just take a look at the task manager. It updates every second
and details the memory usage of each process!

I totally agree. But probably then comes the
question of where the memory goes, and how to
control it.

Memory usage (on the heap) can be controlled by
using the -Xms and -Xmx parameters of the sun java
tool. There is a nice article on this on IBM's
developerWorks site:
http://www-4.ibm.com/software/develo...heap-size.html

And for people who think that memory leaks are not
possible in java, here is the cold shower:

(or search on "memory leaks" at www.java-zone.com)
java does not make clean design an thorough thinking unneeded, in fact it
should invite you to do the exact opposite.

There is a tool called JProbe that seems to be the best profiling tool for
java. As far as I know it can tell exactly where your memory leaks happen
