Edit the Runtime Environment Configuration of App Launchpad

To add a system proxy for accessing resources, or to increase the Java Virtual Memory, you can edit the Java Runtime configuration of App Launchpad.

To edit the runtime environment, you edit the /opt/vmware/alp/ALPJavaEnvironments file.

Caution: Edit the runtime configuration cautiously, as incorrect values can lead to a failure to start App Launchpad services.

Procedure

1. Open an SSH connection to the App Launchpad machine.
2. Using a text editor, open the /opt/vmware/alp/ALPJavaEnvironments file.
3. To create a system proxy, append the following parameters and save the file.

   -Dhttp.proxySet=true
   -Dhttp.proxyHost=${proxy_host_fqdn_or_ip}
   -Dhttp.proxyPort=${proxy_port}
   -Dhttps.proxySet=true
   -Dhttps.proxyHost=${proxy_host_fqdn_or_ip}
   -Dhttps.proxyPort=${proxy_port}

4. Restart App Launchpad services by running the systemctl restart alp command.
5. Verify that the runtime environment is successfully updated by running the ps -elf | grep java command.
   The system returns the following command history, which includes your parameters:

   java 
   -Dhttp.proxySet=true
   -Dhttp.proxyHost=… -jar /opt/vmware/alp/alp.jar --logging.path=log
