IEnlistmentNotification.Commit Method (Enlistment)
Notifies an enlisted object that a transaction is being committed.
Assembly: System.Transactions (in System.Transactions.dll)
The transaction manager calls this method of an enlisted object during the second phase of a commitment, when it instructs all participants to commit the transaction.
The resource manager should perform any work necessary to finish the transaction and then inform the TM that it has finished by calling the Done method on the enlistment parameter.
If the resource manager has enlisted durably, but does not respond by calling Done method, the transaction manager is unsure that the resource manager has received the call. As such, the transaction manager keeps waiting for a response, and maintains information relevant to this transaction. If Done is never called, this piece of information is kept around indefinitely in memory or in a system-wide resource. This results in resources not being able to be reclaimed. In the case of a distributed transaction, this could eventually fill the MSDTC log which halts the MSDTC process. In the case of a transaction managed by System.Transactions, this results in a gradual and continual increase in the memory consumption of the resource manager's process. Therefore, it is crucial that you call the Done method once your resource manager is done with your prepare work.
