10.2.9 Configuring Oracle Connection Manager in Traffic Director Mode for Planned Down Events
Oracle Connection Manager in Traffic Director Mode implicitly subscribes to Fast Application Notification (FAN) events. For this events must be enabled in oraaccess.xml.
For planned down events, use DBMS_SERVICE or SRVCTL to configure the service and set failover_mode to select, commit_outcome to TRUE, and failover_restore to LEVEL1.
