OpenTP1 recovery can be classified into:

• partial recovery
• complete recovery

In partial recovery, OpenTP1 recovers a UAP by performing a commit or rollback operation (usually a rollback) on incomplete transactions. Partial recovery localizes the effects of the UAP failure to the single UAP, and preserves the integrity of the resources used by that UAP.

In complete recovery, OpenTP1 recovers from a complete system failure. This requires a partial recovery for every UAP executing when the system went down, as well as recovery of the various OpenTP1 system statuses.

For further details, see the manual OpenTP1 Operation.
