you must also specify something to execute :) example: java -Xmx128m -Xmx256m com.mycompany.HelloWorld

As long as the JVM can reclaim memory, you should be alright. For your second question, it should look something like this: JAVA -Xms128m -Xmx256m Where -Xmx256m is your "maximum heap size". It gave you that error because the default is 80 megs (which I'm having trouble with), so setting the minimum above 80 megs gives you the error message. http://java.sun.com/j2se/1.4/docs/tooldocs/windows/java.html For the windows standard and non-standard options (such as -Xms and -Xmx). Hope that clears it up for you. -----Original Message----- From: Patrick Codere [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 15, 2002 1:10 PM To: 'Tomcat Users List' Subject: OutOfMemory Error Hi, outofmemory problem crashes my Standalone Tomcat Server(NT 4, Tomcat 4.03). large images on the site. From reading on subject, seems I have to increase the JVM heap size. Question? I created a jsp page that shows me the Total memory and Free memory on the site. The free memory balances between a number and another getting smaller and smaller until it crashes. If I add memory, does that only mean its going to take longer before it crashes? Question? writing JAVA -Xms128m get Incompatible initial and maximum heap size Please help Pat -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
