Cassatt Active Response Administration
Intended for use with Cassatt Active Response Standard Edition, Premium Edition and Data Center Edition V5.1.
Cassatt Active Response requires minimal maintenance. This article describes the best practices, and the few simple tasks for interacting with the Cassatt Active Response software.
Best practices
Because the control nodes are the automatic management system for your Cassatt Active Response environment, you will not want to interrupt control node activities very often. Cassatt recommends these best practices whenever you perform actions on a control node.
| Best practice |
Description |
| Use Cassatt-provided commands or the Cassatt Active Response Controller |
Always use the Cassatt commands or the Cassatt Active Response Controller to interact with Cassatt Active Response and the contents of the /cassatt directory. Cassatt Active Response commands are designed to accommodate failover, and clean up any tasks that are incomplete when failover occurs.
If you use a shell to edit items in /cassatt, you risk interruption of a task if a failover to the standby control node is in progress. A task that is interrupted could leave behind corrupted files and other debris.
Using Linux commands on Cassatt Active Response files can cause problems. For example, using the rm command to remove an image can disrupt services and leave behind clutter, and editing image files can also affect upgrade. |
| Run the Cassatt Active Response Controller in one browser window per machine |
Do not run the Cassatt Active Response Controller in more than one browser window on the same computer. The Cassatt Active Response Controller state can become confused across multiple browser windows. |
