Abstract
A computer system and method are provided in which an existing database instance is able to report the status of an externally initiated distributed transaction that existed in another database instance that has crashed. The existing database instance is also able to roll back or commit the changes made by the externally initiated distributed transaction in response to instructions from the external coordinator process that initiated the transaction. Because the existing database instance is able to perform these services, the external coordinator process does not have to wait for the crashed database instance to be revived to complete the distributed transaction.
