好开发

 IBM HeapAnalyzer是一款免费的JVM内存堆的图形分析工具，它可以有效的列举堆的内存使用状况，帮助分析Java内存泄漏的原因。

下载解压后有一个ha413.jar

运行环境要求：

1、使用 Java 2 Platform,JDK 1.6或以上来运行IBM HeapAnalyzer

2、然后配置好环境变量

运行命令：

<Java path>java –Xmx[heapsize] –jar ha<HeapAnalyzer version>.jar <heapdump file>

举例：

/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 should not be larger than the size of available physical memory size for this tool due to performance issue.
