Some sub_transactions are not compensable in CSCW system. If the recovery technique in database is adopted, the recovery of cooperative transaction will not be realized completely. To make it sure that cooperative transaction can be finally committed or aborted, extension schedule must be constructed. This paper discusses the recovery of cooperative transaction for semantics_based cooperative transaction model.
