Analysis of Java heap dump tools

IBM
Heapanalyzer is a free graph analysis tool for JVM memory heap. It can effectively list heap memory usage and help analyze the causes of Java Memory leakage.

 

After downloading and decompressing the package, there is a ha413.jar

Running environment requirements:

1. UseJava 2 Platform, JDK
Run IBM heapanalyzer 1.6 or more

2. Configure the environment variables.

Run the following command:

<Java path> JAVA-xmx [heapsize]-jar ha

Example:

/Usr/java60/bin/Java-xmx1000m-jar ha146.jar heapdump1234.txt

If there's Java. Lang. outofmemoryerror while you are processing heapdumps, please try increasing the maximum heap size (-xmx) value to give the JVM more memory.

Maximum heap size shocould not be larger than the size of available physical memory size for this tool due to performance issue.

 

Execution result:
