IDOL Site Admin 24.1

# Configure the Java Heap Size

You can configure the Java heap size for IDOL Site 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.idolsiteadmin.home=[home directory] -Dserver.port=[port] -jar siteadmin.jar

  The default value is 1024.

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

If you run IDOL Site Admin as a service on Linux, you can modify the `JAVA_MAX_HEAP_SIZE` variable in the start scripts (`siteadmin.sh` for SystemV, `siteadmin.conf` for Upstart, or `siteadmin.service` for systemd).

When you modify the IDOL Site Admin configuration by modifying the XML file or start scripts, you must restart IDOL Site 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 siteadmin restart` to restart the service.
