Transaction Management
In the case of context-sensitive access, a session can also encompass calls to multiple
server classes. The dialog with each server class is a subsession within the session. A
SOAP server class that provides access to context-sensitive services must consist of
only one server process (Maxservers=1 in the server class configuration).
A client requests a session by including a specific element in the SOAP request
header. The SOAP server returns a session ID, which the client must include in all
subsequent requests until the end of the session. The response to a request to end the
session does not include the session ID.
Figure 1-4 represents session context management by a SOAP server for TS/MP
services. For more detailed information, see Session Management on page 4-3.
Transaction Management
NonStop SOAP allows a client to begin, commit, or abort transactions within a session.
The underlying technology for transaction control on a NonStop system is HP NonStop
Transaction Management Facility (TMF).
