or group of nodes. If there are no flags, the node or group is
operating normally.
RTR Command
Line Interface
The command line interface (CLI) to the RTR API enables the
programmer to write short RTR applications from the RTR
command line. This can be useful for testing short program
segments and exploring how RTR works. Figure 4–2 shows
the RTR CLI interface. For example, the commands shown in
Examples 4-1 to 4-4 start RTR and exchange a message between
a client and a server.
Note
The channel identifier identifies the application process
to the ACP. The client and server process must each have
a unique channel identifier. In this example, the channel
identifier for the client is C and for the server is S. Both
use the facility called DESIGN.
Sample TP
The examples that follow show transaction processing (TP)
communication between a client and a server created by entering
commands at a terminal keyboard. The client application is
executing on the frontend and the server on the backend.
The operational process is:
• Create the journal
• Create a facility
• Create a partition
• Open channels
• Start a transaction
• Accept the transaction
All applications will use some variants of these steps in the same
order.
The user is called user, the facility being defined is called
DESIGN, a client and a server are established, and a test
message containing the words "Kathy’s text today" is sent from
the client to the server. After the server receives this text, the
user on the server enters the words "And this is my response."
