AEM author fail to start with jvm error

[subrato_kha]

Hi All,

We are facing below error when we are trying to start AEM. AEM fails to start with 

below entry in our stdout.log file
Unrecognized VM option 'MaxPermSize=512M'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

Has anyone faced this issue?

I hope you are starting the AEM from Command Line

Use the following command 

java -Xmx1024M -jar cq-quickstart-p4502-6.5.0.jar 

or if you need startup gui then add

java -Xmx1024M -jar cq-quickstart-p4502-6.5.0.jar  -gui

 Option MaxPermSize=256m; support was removed in 8.0 Java.

Also refer this documentation for memory arguments setup instide batch file and starting via batch file itself.

Hope it helps.

Hi @subrato_kha 

If you are using AEM 6.5 then you can use the below command to start AEM.

java -jar AEM_6.5_Quickstart.jar -r author -Xmx2048m -XX:+UseParallelGC --add-opens=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED --add-opens=java.base/sun.net.www.protocol.jrt=ALL-UNNAMED --add-opens=java.naming/javax.naming.spi=ALL-UNNAMED --add-opens=java.xml/com.sun.org.apache.xerces.internal.dom=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/jdk.internal.loader=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED -Dnashorn.args=--no-deprecation-warning
