The new database applications need complicated integrity checking rules. Update transactions in new database applications require a large number of complicated integrity checkings. In case of system failure many transactions may be in state of integrity constraint checking phase and be highly likely rollbacked. Since, however, many transactions satisfy the integrity constraints generally, it causes the system resources to be wasted to rollback the transaction at system recovery phase. This paper proposes the recovery mechanism for integrity checking transactions. It does not rollback the integrity checking transaction at system recovery phase. After recovery phase, the system may continue to execute the remaining integrity constraints of the transaction. By simulation, we examine the validity of the proposed recovery mechanism. |
