Understanding script resources<br />

You can register scripts managed by <strong>ExpressCluster</strong> and run when starting, stopping, failing over,<br />

or moving a group in <strong>ExpressCluster</strong>. It is also possible to register your own scripts <strong>for</strong> script<br />

resources.<br />

Note:<br />

The same version of the application to be run from script resources must be installed on all<br />

servers in failover policy.<br />

Dependencies of script resources<br />

By default, this function depends on the following group resource types.<br />

Group resource type<br />

Scripts in script resources<br />

Types of scripts<br />

Start script and stop script are provided in script resources. <strong>ExpressCluster</strong> runs a script <strong>for</strong> each<br />

script resource when the cluster needs to change its status. You have to write procedures in these<br />

scripts about how you want applications to be started, stopped, and restored in your cluster<br />

environment.<br />
