jmeter — java.lang.OutOfMemoryError: Java heap space解决方案

添加了一个超大返回数据量(超过100M)，jmeter default 的配置hold不住了，直接报 java.lang.OutOfMemoryError: Java heap space 的错误。

查询userguide，发现：To run JMeter, run the jmeter.bat (for Windows) or jmeter (for Unix) file

我猜到了要这种文件，以为在linux上改下jmeter.sh就OK，结果还是有问题，用top -d 1 (shirt +m) 查看memory使用情况，木有什么变化。 真是聪明反被聪明误。

大家还是好好看看：

for windows:

jmeter.bat - run JMeter (in GUI mode by default)

jmeter-n.cmd - drop a JMX file on this to run a non-GUI test jmeter-n-r.cmd - drop a JMX file on this to run a non-GUI test remotely jmeter-t.cmd - drop a JMX file on this to load it in GUI mode jmeter-server.bat - start JMeter in server mode mirror-server.cmd - runs the JMeter Mirror Server in non-GUI mode shutdown.cmd - Run the Shutdown client to stop a non-GUI instance gracefully stoptest.cmd - Run the Shutdown client to stop a non-GUI instance abruptly

for linux:

jmeter - run JMeter (in GUI mode by default). Defines some JVM settings which may not work for all JVMs.

jmeter-server - start JMeter in server mode (calls jmeter script with appropriate parameters) jmeter.sh - very basic JMeter script with no JVM options specified. mirror-server.sh - runs the JMeter Mirror Server in non-GUI mode shutdown.sh - Run the Shutdown client to stop a non-GUI instance gracefully stoptest.sh - Run the Shutdown client to stop a non-GUI instance abruptly

如果改这些文件不起作用或者想override的话

windows 可以这样写：set JVM_ARGS="-Xms1024m -Xmx1024m -Dpropname=propvalue"jmeter -t test.jmx ...

linux可以这样写：JVM_ARGS="-Xms1024m -Xmx1024m" jmeter -t test.jmx [etc.]
