Thread Safety

Remarks

BYOT (Bring Your Own Transaction) allows a component to be created with or to inherit an external transaction. That is, a component that does not already have an associated transaction can acquire a transaction. COM+ allows setting an arbitrary pre-existing DTC or TIP transaction as the transaction property of a new component's context. This allows COM+ components to be associated with transactions whose lifetimes are controlled by a TP monitor, OTS, or DBMS.

BYOT transactions must be used with caution. In certain situations, they can result in a transaction spanning multiple synchronization domains-that is, they allow parallelism with another transaction, causing a deadlock condition.

Automatic transactions, rather than BYOT transactions, are the preferred programming model for writers of business components.
