I search and searched and could never find this info so sharing this here with others.
If you want to restart the catalog service on the Portfolio server run this:
#!/bin/sh
#Stop the catalog service
sudo launchctl unload /Library/LaunchDaemons/com.extensis.portfolio.server.media.delegate.plist
#Start the catalog service
sudo launchctl load /Library/LaunchDaemons/com.extensis.portfolio.server.media.delegate.plist
If you want to set the server address on the Portfolio Desktop you need to capture these files from a Mac already setup with Jamf Composer.
