IAbstractSessionOpenServiceAsync(String, CorrelationID)
Exceptions
ExceptionCondition
InvalidOperationException The session is not started.
DuplicateCorrelationIDException The specified correlationId is already active for this Session.
Remarks
Initiates a request to open the service identified by serviceName. serviceName must be a fully qualified service name. That is, it must be of the form "//[namespace]/[service-name]".

Once the request has completed, a SERVICE_STATUS event will be generated indicating the result of the request. The correlationId will be returned in generated message. It can also be used to cancel this request before it completes by calling the Cancel operation. Note the supplied correlationId MUST BE unique from any "active" correlation supplied to this session via any operation(e.g., "subscribe", "sendRequest"). A correlation id is active if the request for which it was supplied is still pending, or if it refers to a subscription request that has not been terminated either explicitly or by an unsolicited termination.
