Editing the memory and JVM settings for Talend CommandLine

Last updated: 8/28/2025

Talend CommandLine as a Server is deprecated from Talend 7.1 onwards.

To gain in performance at runtime and when launching Talend CommandLine, you can edit the memory settings in the corresponding .ini file.

Procedure

Edit the Talend-Studio-linux-gtk-x86_64.ini file.
Edit the memory attributes. For example:
-vmargs -Xms512m -Xmx1536m -XX:MaxMetaspaceSize=512m
Information noteTip: For big projects, you may need to increase Xmx to 4096m.

For more details, see http://www.oracle.com/technetwork/java/hotspotfaq-138619.html.
Edit the commandline-linux_x86_64.sh file.

Change the following information:

./Talend-Studio-linux-gtk-x86_64 -nosplash -application 
org.talend.commandline.CommandLine -consoleLog -data 
commandline-workspace startServer -p 8002

/My_Jvm_Path/java -jar
plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar
-nosplash -application org.talend.commandline.CommandLine
-consoleLog -data commandline-workspace startServer -p 8002
-vmargs -Xmx1536m -XX:MaxMetaspaceSize=512m
