Jenkins不以-Xrs -Xmx2048m -XX：MaxPermSize = 512m开头（Windows）

Question

My Jenkins does not want to start with parameters -Xrs -Xmx2048m -XX:MaxPermSize=512m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\\jenkins.war" --httpPort=8080 in jenkins.xml file. I also added JENKINS_HOME variable to windows variables and set path to my jenkins folder c:\\Program Files (x86)\\Jenkins . But it does not help. I see in the log file error

Error: Could not create the Java Virtual Machine. 
Error: A fatal exception has occurred. Program will exit. 

Can somebody help me?

Answer 1

Most likely you are using 32-bit JVM on Windows. This has a heap limit of about 1.2 - 1.5 GB depending on what you have run before.

I suggest either limiting yourself to -Xmx1200m or use a 64-bit JVM.

If you increase the PermGen, you need to decrease the heap size as the amount of virtual memory you can have in 32-bit windows is limited.

I found solution. Need to update JRE version of Jenkins in its folder. I just copied new files to its folder and replaced the same files) Now I can start Jenkins with option

<arguments>-Xrs -Xmx2048m -  Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar   "%BASE%\jenkins.war" --httpPort=8080</arguments>

Also I use soap ui api for running tests in Jenkins. I changed option

set JAVA_OPTS=-Xms512m -Xmx2048m -Dsoapui.properties=soapui.properties "-Dsoapui.home=%SOAPUI_HOME%\"

in testrunner.bat And now my tests are run correctly and there are no errors Perm Gen!
