1.3.1 Context Properties

This protocol operates by passing COM+ specific information in object activations, ORPC calls, and as part of marshaled OBJREFs, using the context and context property extension mechanisms as specified in [MS-DCOM] section A COM+ object is configured using an implementation-specific mechanism to require none, some, or all of the features described in this specification. These features are implemented by creating the object within a context and associating properties with the context. A context is a collection of attributes or context properties that describes an execution environment. When an object in a context with one or more context properties creates or calls other objects on the network, the protocol specifies mechanisms for those context properties to influence the state of the object activations and ORPC calls.

A context can contain the following context properties:

  • The Transaction Context Property (section 1.3.2)

  • The Activity Context Property (section 1.3.3)

  • The Security Context Property (section 1.3.4)

  • The User-Defined Context Property (section 1.3.5)
