Cumulus comes with a number of commands installed in /usr/local/Cumulus_Workgroup_Server. The assets can be in a shared directory location, such as an NFS mount mapped to /cumulus or /Volumes/Cumulus. But in the /usr/local/Cumulus_Workgroup_Server directory there are a number of commands that can be pretty useful. For example, the stop-admin, stop-cumulus, start-cumulus and start-admin commands can be used to restart the Cumulus using a simple ARD template:
There are others, such as status.sh, which shows size of repository, PIDs, and the time running. The repair.sh can be used to repair the database and remove-admin.sh and remove-cumulus.sh can uninstall the admin console and cumulus servers respectively (danger, Will Robinson). The install-admin.sh and install-cumulus.sh scripts can also be used to install these items respectively. The bin directory contains daemons such as cumulusd and services information/cumulusrad.
If you want to work with assets, you’ll probably need the Java SE JDK to run and then query the Tomcat server. This web application environment leverages Cumulus Java classes to provide the API that can then be scripted into various workflows, such as providing a site that queries images in the DAM and displays those matching a given pattern on a website.
Overall, the scripting that can be done without the API is service control oriented, but with the API and a little SOAP you can pretty much grab or change almost anything you need to.
