SmartObject

Transaction Support in Service Instances

               All Service instances are instantiated and executed as part of a Transaction Scope in the SmartObjectBroker. The transaction option as specified on the SmartObject method determines the TransactionScopeOption.

We have three options:

1. Continue: TransactionScopeOption = Suppressed - No transaction, all services (execution blocks) will execute even if one or more fail.
2. Stop: TransactionScopeOption = Suppressed – No transaction, execution will halt immediately after first service execution fails.
3. Rollback: TransactionScopeOption = Required – A root transaction is created and will be the relating transaction for all participating services to obtain in.

The concept of Transaction Scope and ambient transactions is clearly explained in the following article
