How many types of Transactions are there in COM + .NET ?
.NET INTERVIEW QUESTIONS - How many types of Transactions are there in COM + .NET ?
There are 5 transactions types that can be used with COM+. Whenever an object is registered with COM+ it has to abide either to these 5 transaction types.
Disabled: - There is no transaction. COM+ does not provide transaction support for this component.
Not Supported: - Component does not support transactions. Hence even if the calling component in the hierarchy is transaction enabled this component will not participate in the transaction.
Supported: - Components with transaction type support will be a part of the transaction. This will be only if the calling component has an active transaction. If the calling component is not transaction enabled this component will not start a new transaction.
Required: - Components with this attribute require a transaction i.e. either the calling should have a transaction in place else this component will start a new transaction.
Required New: - Components enabled with this transaction type always require a new transaction. Components with required new transaction type instantiate a new transaction for themselves every time.
