EVENT_TIMEOUT Connection Manager configuration parameter

The EVENT_TIMEOUT parameter specifies the number of seconds that must elapse with no primary-server events before the active-arbiter Connection Manager starts failover processing. The Connection Manager waits for primary-server events or notifications from secondary servers that the primary server is offline. A primary-server event is an indication from the primary server that the server is still functioning, such as a sent performance-statistics or administration messages, or node-changes.
