Chapter 14 Introduction to the Call Level Interface : Valid Calling Sequences

Valid Calling Sequences
You must call Call Level Interface functions in a particular sequence. For example, before you can start a session, you must first start an Execution Environment. In general, you cannot use the functionality of a TIBCO Object Service Broker object until it has been explicitly created by starting it and you cannot create a TIBCO Object Service Broker object until the appropriate environment has been established.
Calling Sequence
 
External Environment
In a multiple-session environment, the Execution Environment must be started separately, which is normally done as part of standard operations. This process establishes, at start-up, the concurrent number of standby sessions deemed necessary for the connect of the interface.
The STOPSS function terminates the session. Session termination releases the standby session and makes it available to other calling programs.
Permissible Transitions Between the Call Level Interface Functions
The following illustration shows the permissible transitions between the Call Level Interface functions. Invalid calling sequences generate a non-zero RETURN-CODE.
