Session Disconnection, Load Rebalancing, and TAF
None of the manuals, including the latest Oracle11g release 1 editions, indicate any link between ALTER SYSTEM DISCONNECT SESSION and Transparent Application Failover (TAF). This is also true for a transactional shutdown of an instance, that is, a shutdown operation, which is deferred until all clients have committed or rolled back their work, with the command SHUTDOWN TRANSACTIONAL. A third undocumented link exists between the disconnection of sessions with the PL/SQL package DBMS_SERVICE in Oracle10g as well as Oracle11g and TAF.
