Enlists a resource manager that has an internal transaction using a promotable single phase enlistment (PSPE).
Assembly: System.Transactions (in System.Transactions.dll)
[PermissionSetAttribute(SecurityAction.LinkDemand, Name = "FullTrust")] public bool EnlistPromotableSinglePhase( IPromotableSinglePhaseNotification promotableSinglePhaseNotification )
- Type: System.Transactions.IPromotableSinglePhaseNotification
A IPromotableSinglePhaseNotification interface implemented by the participant.
Enlistments in a transaction are volatile; that is, they do not survive the failure of the participant. In addition, this method only suggests the transaction manager to escalate control, but the escalation itself is not guaranteed. If escalation fails, the user is not notified and the transaction is rolled back.
The parameter promotableSinglePhaseNotification is used to communicate to the transaction manager the outcome of attempting to commit the resource manager's internal transaction. If inconsistent data is reported, the transaction manager throws an exception. If an InDoubt outcome is reported, the transaction manager looks for the outcome notification in its own internal enlistment and ignores the reported response.
For more information on enlistments and escalation of a transaction, please see Transaction Management Escalation. For more information on PSPE, see Optimization Using Single Phase Commit and Promotable Single Phase Notification.
Note This method uses LinkDemand to prevent it from being called from untrusted code; however, only the immediate caller is required to possess the FullTrust permission set.
