(3) Failover at the failed server1
The start script of a group that has server1 as its primary server will be run on a lower priority
server (server2) if an error occurs. You need to write CLP_EVENT(=FAILOVER) as a
branching condition for triggering application startup and recovery processes (such as database
rollback process) in the start script in advance.
For the process to be performed only on a server other than the primary server, specify
CLP_SERVER(=OTHER) as a branching condition and describe the process in the script.
