Hello all,
I read the documentation on the Tomcat6 site and I have attempted to modify the max jvm memory settings when tomcat starts up by modifying Catalina.bat, but it *appears* to have no effect. Here is a summary of the situation and what I have done. I am using Tomcat6 stable release, WinXP, java 1.6 I am running tomcat from zip distribution and not from an installed windows service. I am using the startup/shutdown .bat files to start/stop my tomcat instance I have run some test code in a simple web service inside of tomcat to determine the max memory settings for the JVM that tomcat is using. Runtime rt = Runtime.getRuntime(); return rt.maxMemory(); the value that gets returned : 66650112 I shutdown tomcat, and modified Catalina.bat with the following in the JAVA_OPTS section(I included the surrounding remarks for context) rem JAVA_OPTS (Optional) Java runtime options used when the "start", rem "stop", or "run" command is executed set JAVA_OPTS = -Xms512m -Xmx512m I then restarted tomcat, ran my service call above and it still returns the same value for maxmemory from within my tomcat webservice. >From reading the Tomcat Docs/ FAQ, and Googling I think that I am setting what I need to set(Catalina.bat), but it seems to have no effect. What resource am I not taking advantage of with this information, or what am I missing to set the max memory usage in the JVM when Tomcat starts up? Thank you for your time in reading this, Chris
