Recommendations before Configuring the Cluster
Before proceeding to configure the SBR Carrier nodes and the SSR database, remember that you are configuring a set of machines to act as one entity. You must take some special steps to keep them all working together.
We recommend that you follow these guidelines:
Always create a backup file before making any modifications to any file.
Remember that certain files must be the same on all nodes of the same type. To make this easier to manage, include a comment in modified files that records the date and type of modification.
To implement changes, one or more processes often need to be restarted to force modified files to be read and used. Controlling restarts precisely is easier if you become familiar with the sbrd script and its parameters.
