How do you assign xmx and mxs memory to shared users under tomcat 5.9

Hello

I am able to compile a class under our shared tomcat 5.9 environment as long as I log on as root. If I log on as a shared user and submit the same compile options, I receive

"Error occurred during initialization of VM, Could not reserve enough space for object heap, Could not create the Java virtual machine."  

The compile code is below;

javac -J-Xms30m  -J-Xmx40m -cp /home/mikeippo/www/WEB-INF/classes/beans/*.java -sourcepath /home/mikeippo/www/WEB-INF/classes/beans -classpath /home/mikeippo/www/WEB-INF/classes/beans:/home/mikeippo/www/WEB-INF/classes:/home/mikeippo/www/WEB-INF/lib/servlet.jar:/home/mikeippo/www/WEB-INF/lib/mail.jar

We have tried just about every combination of xms / xmx memory values and always get the same results.  This leads us to the conclusion that there is no xms/xmx memory assigned to a shared user.


Question:

Where do we assign xms/xmx memory to a shared user in our configuration. I believe that it is in the server.xml but cannot find the parameters

We asked this question in our last Request Title: Users Cannot compile under shared tomcat 5.9 but it appeared that the person who was helping us did not know the answer and gave up because he has not responded in about a week.  This left us hanging, so we created another question.

Your help is much appreciated

Ken

Tomcat 5.9? The latest versions are 5.5.17 and 5.0.28. Which version do you mean?

Can I ask why you are compiling the java code on the server? It's more normal practise to compile the code on your own machine and then upload the generated  class files to tomcat.

I don't think that you can specify these parameters in the server.xml or context.xml. Also, that it works as root user but not as shared indicates to me that this is more likely a permissions issue.

Hi Sorry it is 5.5.9

I have customers who want to contil on the server but after hearing what you had to say, "It's more normal practise to compile the code on your own machine and then upload the generated  class files to tomcat." then I think that I will leave it that way.  If I start getting a 100 tomcat users compiling at the same time it will cause problems, so why open pandoras box.

Thank-you for your help.

Glad to help Ken :-)

I've worked from companies varying from small one franchises to investment banks and telecoms companies and uploading the class files (or better yet, war files) has always been standard practise.
