A computer system coordinates the handling of error codes and information describing errors in a commit procedure. The system supports a first resource manager of a first type and a second resource manager of a second type. An application is coupled to a sync point manager and initiates a two-phase commit procedure. The sync point manager is coupled to the first and second resource managers and coordinates the two-phase commit procedure involving the first and second resource managers. The sync point manager receives notification of a failure or failures relating to the first and second resource managers that prevent completion of the commit procedure and identification of the resource manager or resource managers associated with the failure or failures. The sync point manager sends to the application a failure notification after receipt of the notification of a failure or failures relating to either or both of the resource managers, and upon request, also sends to the application the identification of the resource manager or resource managers associated with the failure or failures. The sync point manager also receives cause of failure information for each failure, and sends the cause of failure information to the application upon request.
