Hi.
I'm quite new to linux and am trying to set up java (JDK) on a virtual server via SSH.
Although I've installed the JDK, I need to limit it's memory whenever it's run from the ssh terminal window AND by other applications.
To do this I need the parameters '-server -Xms16m -Xms32m' to be automatically included whenever java is run.
I've tried setting JAVA_HOME and JAVA_OPTS variables via editing ~/.profile however this has no effect.
I also tried renaming the executable and creating an alias, which worked fine for when I ran java from ssh terminal, however when apache ant tried to use java it looks directly for the java executable (alias doesn't work).
I'd really appreciate any help that can be given, as it seems like it should be a relatively easy thing to do (?)
The version of linux being run is Red Hat enterprise 3.
Thanks

if this is when the "java" command itself is run, you can always just use an alias:

alias java='java -server -Xms16m -Xms32m'

in your ~/.profile or ~/.bashrc

but there may be a more java specific way to achieve this.

You could write a wrapper script and call that instead of java directly. It might contain something like this:
Rename the original java to java.orig, and put this script where the original was...

Thank you both for your suggestions.
I had tried to create an alias before - and as pointed out, it only worked from the command line.
Writing the wrapper script has enabled me to do what I was after.
Thanks again
