Problem with the JRockit
I hope to run the tomcat 5.0 with JRockit 5.0 R26.3.on a linux machine and installed JRockit in the root directory (/root/jrockit-R26-3.0-jdk1.5.0_06) The following is the environment variables which I set:** export JAVA_HOME=/root/jrockit-R26-3.0-jdk1.5.0_06 export JAVA_HOME PATH=$JAVA_HOME/bin:$CATALINA_HOME/bin:$PATH export PATH export CLASSPATH=/root/jrockit-R26-3.0-jdk1.5.0_06/lib/tools.jar:/root/jrockit-R26-3.0-jdk1.5.0_06/jre/lib/rt.jar:./ export CLASSPATH=$CLASSPATH:/var/tomcat/common/lib/servlet-api.jar export CLASSPATH=$CLASSPATH:/var/tomcat/common/lib/mysql-connector-java-3.1.12-bin.jar export CLASSPATH=$CLASSPATH:/root export CATALINA_HOME=/var/tomcat export CATALINA_HOME However, when I start the tomcat (./startup.sh), I received the following message: The JAVA_HOME environment variable is not defined correctly This environment variable is needed to run this program NB: JAVA_HOME should point to a JDK not a JRE I double checked the environment variables which I set and there is no typo. The tomcat runs very well if I use Sun J2EESDK . Is there something wrong with the configuration? Thank you very much!
Re: When does the MarkSweepCompact Garbage Collector perform GC?
Thanks for the reply! Does this kind of the GC only run when the memory usage almost reaches the limit which we allocate (for example, by default, it is 64 MB)? Sorry that I am not familiar with the GC. I just know that the JVM would do it for us by itself.

What makes you think the GC should run? Are you out of memory? The GC will not run in many situations unless it has a need to.

Hello! Now I am using the jconsole to monitor the heap memory usage of the tomcat 5.5. I've constructed a testbed to test the performance of the applications running on the tomcat. However, the jconsole shows that the MarkSweepCompact Garbage Collector never does its job. The only two ways to make this garbage collector to perform GC are: 1 I push the button perform GC shown on the Memory tab of the jconsole 2 I insert the code System.gc() into the servlets. I think both of these two ways are not good, and this garbage collector should perform GC automatically (in my opinion). I just wonder when or under which conditions the MarkSweepCompact Garbage Collector would perform GC. Or actually there is something wrong with my configuration so it doesn't perform GC?
