RAM needed to run WAS and analysis tools
|
|
|
| Hi all-
The org I work for just decided to go with WAS for our test, staging, and production app server. As such, we are trying to get WAS, the Heap Analyzer, and the AST to run on the same Linux box with 2GB of RAM. We're running into a problem though, and are
having to choose between running WAS or the Heap Analyzer or the AST--but not all three (or even 2 for that matter) at once. Are WAS, HA, and the AST just memory hogs, or are we doing something wrong?
Thanks in advance for any help.

What else is on the box? Are you running multiple instances of WAS on
the same box? What problem are you running into?
I would suspect that you can do all of those on the same box, but it
would depend on your app's memory requirements.

| We have WAS, Heap Analyzer, and the AST installed on the box right now, and only have one instance of WAS running. To run our app effectively, it usually takes 1.5 GB of the available 2 GB of memory, but that's only for the server itself. We need to run
HA and the AST as well as WAS so we can effectively profile the app and analyze the heap dump when it is triggered, but we are running out of memory if we have more than just the app server running on the box.

You should be able to run HA and AST on a developer's machine, rather
than a production/test box.
