Abstract
Disclosed is a data processing system-implemented method, a data processing system and an article for manufacture for directing a data processing system to roll back to a savepoint located in a unit of work having a boundary generated by a boundary generator. The data processing system-implemented method includes examining a savepoint status indicator associated with the savepoint, and rolling back past the boundary to the savepoint depending on whether the examined savepoint status indicator indicates rolling back past the boundary towards the savepoint is permitted.
Claims21
A data processing-system implemented method for directing a data processing system to roll-back to a savepoint, having an associated savepoint status indicator, located in a unit of work having a boundary generated by a boundary generator, the data processing system-implemented method comprising the steps of:
- examining the savepoint status indicator;
- and
- rolling-back past the boundary to the savepoint responsive to the examined savepoint status indicator indicating rolling-back past the boundary towards the savepoint is permitted.
An article of manufacture for directing a data processing system to roll-back to a savepoint, having an associated savepoint status indicator, located in a unit of work having a boundary generated by a boundary generator, the article of manufacture comprising:
- a data processing system usable medium tangiblely embodying one or more instructions executable by the data processing system, the one or more instructions comprising:
- data processing system executable instructions for examining the savepoint status indicator;
- and
- data processing system executable instructions for rolling-back past the boundary to the savepoint responsive to the examined savepoint status indicator indicating rolling-back past the boundary towards the savepoint is permitted.
A data processing system for rolling-back to a savepoint, having an associated savepoint status indicator, located in a unit of work having a boundary generated by a boundary generator, the data processing system comprising:
- an examination module for examining the savepoint status indicator;
- and
- a rolling-back module for rolling-back past the boundary to the savepoint responsive to the examined savepoint status indicator indicating rolling-back past the boundary towards the savepoint is permitted.
