Decoupled applications list without connection concentrator enabled

It is possible to see decoupled applications when issuing the list applications command even without connection concentrator enabled.

Progress monitoring of the run time rollback process

Progress monitoring of run time rollback provides progress information 7of rollback events using application snapshots. Rollback events are of two 7types:

7

Unit of work rollback

7

Includes explicit (user invoked) and implicit (forced) rollback of the 7entire transaction. 7

7

Savepoint rollback

7

Includes statement and application level savepoints. Nested savepoints 7are considered a single unit, using the outermost savepoint. 7

7

The information provided is the start time of the rollback event, the total 7work to be done, and completed work. The work metric is bytes.

Total Work units is the range in the log stream that needs to be rolled 7back for the transaction or savepoint.

Completed Work units shows the relative position in the log stream that 7has been rolled back.

Updates to Completed Work are made after every log record is processed. 7 Updates are not performed evenly because log records vary in size.
