Setup Client Failover
1. To setup client failover, you need to add an entry to the dbmapping.txt file in $ACLDIR/config directory:
<cluster_id> = adatcp://<host_name-1>:<adatcp_portnumber-1>?cluster=adatcp:/<host_name-2>:<adatcp_portnumber-2>;adatcp://<host_name-3>:<adatcp_portnumber-3>
2. From the application point of view, the <cluster_id> represents the dbid and can be any number between 1 and 255.
