Configure the Java Heap Size

You can configure the Java heap size for IDOL Data Admin by setting the size in the Java run command.

To configure the Java heap size

  • At the command line, send the java run command with the Xmx"[HeapSize]"m argument set. For example:

    java -Xmx2048m -Didol.dataadmin.home=[home directory] -Dserver.port=[port] -jar dataadmin.jar

    The default value is 1024.

If you run IDOL Data Admin as a service on Windows, you can also add the Xmx property to the dataadmin.xml file.

If you run IDOL Data Admin as a service on Linux, you can set or modify the java heap size in the start scripts (dataadmin.sh for SystemV, dataadmin.conf for Upstart, or dataadmin.service for systemd).

When you modify the IDOL Data Admin configuration by modifying the XML file or start scripts, you must restart IDOL Data Admin to apply your configuration changes.

On Upstart, you must also run initctl reload-configuration before you restart, to apply the init file changes. You can then run service dataadmin restart to restart the service.
