Before starting to work in cluster mode, make sure that:
- two instances of the Tomcat application server are installed and started.
- several execution servers are grouped in a virtual server and are up and running.
For more information on how to group physical servers in a virtual server, see Configuring virtual servers.
In the Job conductor node of the Configuration page, you should use the same folders to store the generated Jobs and the same folders to store the logs. To synchronize these folders, it is recommended to use a file-synchronization tool like Unison to propagate the changes to the two folders, or you should at least use a shared directory to store these folders.
