Abnormal termination involving Db2 and RRS

If Db2 abnormally terminates but RRS remains active, RRS might commit or roll back work without Db2 knowledge. In a similar manner, if RRS abnormally terminates after Db2 has completed phase 1 of commit processing for an application, Db2 does not know whether to commit or roll back the work.

In either case, when Db2 restarts, that work is termed indoubt.

Db2 cannot resolve those indoubt units of recovery (that is, commit or roll back the changes made to Db2 resources) until Db2 restarts with RRS.

If any unit of work is indoubt when a failure occurs, Db2 and RRS automatically resolve the unit of work when Db2 restarts with RRS.
