FP5: Super asynchronous HADR synchronization mode has been added

The HADR synchronization mode determines when the primary database server considers a transaction complete based on the state of the logging on the standby database. Starting in Version 9.7 Fix Pack 5, you can specify SUPERASYNC (super asynchronous) as a synchronization mode in DB2 High Availability Disaster Recovery (HADR) environments.

The new super asynchronous mode complements the existing set of synchronization modes by ensuring that transactions can never be blocked or experience elongated response times due to network interruptions or congestion, therefore allowing transactions to be processed more quickly than in any other HADR synchronization mode.

You enable the super asynchronous mode by setting the hadr_syncmode database configuration parameter to SUPERASYNC.
