Transactions

The OLE DB Provider for Oracle implements local transaction support. The consumer can use distributed or coordinated transactions by using Microsoft Distributed Transaction Coordinator (MS DTC). For consumers requiring transaction control that spans multiple sessions, this provider can join transactions initiated and maintained by the Microsoft Distributed Transaction Coordinator.

By default, the Oracle provider uses an autocommit transaction mode, where each discreet action on a consumer session comprises a complete transaction against an Oracle server. For this provider, autocommit mode is local. Autocommit transactions never span more than a single session.

This provider exposes the ITransactionLocal interface, allowing the consumer to use explicitly and implicitly started transactions on a single Oracle connection. This provider does not support nested local transactions at this time.
