Additional information 1 Section II Resource details Understanding script resources For a group that has three or more servers specified in the failover policy to behave differently on servers other than the primary server, use CLP_PRIORITY instead of CLP_SERVER(HOME/OTHER). OAC OB O (3) X OABC O O OAB OC (6) Server 1 went down, and restarted. (6)A O OABC O Example 1: “(3) Failover at the failed server1” in the cluster status transition diagram A group has server1 as its primary server. If an error occurs on server1, the group’s start script is run on server2 that has next highest priority failover policy. You need to write CLP_EVENT(=FAILOVER) as the branching condition for triggering applications’ startup and recovery processes (such as database rollback) in the start script in advance. For a process to be performed only on the server that has the second highest priority failover policy, you need to write CLP_PRIORITY(=2) as the branching condition.
