RECOVERY OF A TRANSACTION AFTER XA END |
| 摘要 |
Embodiments of the present invention disclose a method for recovery of a two-phase commit transaction. A computer receives an end command prior to completing execution of a prepare command for a transaction identifier. The computer determines if a failure and restart occurred within a distributed data processing environment after a resource manager receives an end command. The computer responds to a determination that the failure and restart did occur within the distributed data processing environment by retrieving the first transaction identifier from a data store. The computer transmits a rollback command for the retrieved first transaction identifier to the resource manager. |
