注意: 1.12.0 Release需要JDK11
参数配置
在配置的部分，我们主要配置的是ParseHeapDump.sh脚本中的内存参数。
在脚本的最后一行的最后面，加上如下的参数
-vmargs -Xmx30g -XX:-UseGCOverheadLimit
具体的内存的大小，要根据dump的大小来修改，设置的太小会出现OOM的情况。
分析dump文件及生成报告
接下来，我们就是要通过ParseHeapDump.sh来分析dump文件
命令如下：
ParseHeapDump.sh <path/to/dump.hprof> [report]*
示例：
./mat/ParseHeapDump.sh ./gl.hprof org.eclipse.mat.api:suspects
执行过程，如下：
[root@nccztsjb-node-27 data]# ./mat/ParseHeapDump.sh ./gl.hprof org.eclipse.mat.api:suspects

执行完成后，会生成一个报告的文件
将这个文件，解压到本地电脑，通过浏览器就可以进行查看，比如：
