如何在不修改jmeter.bat文件的情况下增加JMeter堆大小？

Question

我有多个堆需求的多个脚本。所以如何在不改变bat文件的情况下动态处理它？是否有可能从用户定义的属性文件？环境变量传递堆大小？您可以提出建议。谢谢你在前进

Answer 1

它在getting started手册：

环境变量JVM_ARGS可用于在jmeter.bat脚本来覆盖JVM设置。例如：

set JVM_ARGS="-Xms1024m -Xmx1024m -Dpropname=propvalue" 
jmeter -t test.jmx … 

Answer 2

update your jmeter.sh file as below 
java -server $JVM_ARGS -jar `dirname $0`/ApacheJMeter.jar "$@" 

your executable".sh"(which has all information about jmeter home, script name which needs to be executed) should be as follows---- 
#!/bin/sh 
JVM_ARGS="-Xms2g -Xmx2g" 
JMETER_HOME=/tui/endeca/endeca/ToolsAndFrameworks/jmeter/app/apache-jmeter-3.1/ 
export JVM_ARGS 
export JAVA_HOME 
echo $JAVA_HOME 
echo $JVM_ARGS 
#export JMETER_HOME 
$JMETER_HOME/bin/jmeter.sh -n -t "/tui/endeca/endeca/ToolsAndFrameworks/Script/TH/script.jmx" 

To see the updated heap use the below in JSR223 Sampler(Thanks to Dmitri for solution) 
import java.lang.management.ManagementFactory 
import java.lang.management.RuntimeMXBean 
def runtimeMxBean = ManagementFactory.getRuntimeMXBean() 
def arguments = runtimeMxBean.getInputArguments() 
for (argument in arguments) { 
    println('Effective JVM argument: ' + argument) 
}
