The graph says that Memory Heap in used is almost 95%. How to free memory

Dear 9424419352,

You are running with a 64MB heap, which is really small. I would suggest you raise the heap size to 256MB to see if that helps. Use the -Xmx flag for that.

To free memory, you can use a memory profiler and see what the memory is being used for. Then change the code not to use so much memory.

Dear Kee Jan

As you suggested that I need to increase memory heap to 256 MB. And also u menstioned the flag also. But this not clear to me , in Apache Tomcat server, where I need to mention that. Hope your solution may give me best performance of my web server

Thanks

Dear Dhruba,

Setting this configuration is different for each operating system. Tomcat listens to an environment variable named JAVA_OPTS for things like this. On UNIX-like systems, you can edit the startup script to have do something like this at the beginning:


JAVA_OPTS="${JAVA_OPTS} -Xmx256m"
export JAVA_OPTS


On other systems I don't know how to set that flag, but I am sure that is you Google for "tomcat JAVA_OPTS xmx" you will find more about that.

Please note that you need to restart Tomcat afterwards.
