To start the RAP-processing listener and RAP-processing server, execute the dcsvstart command. Alternatively, you can start the RAP-processing listener and RAP-processing server by starting OpenTP1 with the dcsvstart definition command specified in the user service structure definition.

If you execute the dcsvstart command with the name of the RAP-processing listener specified as a command argument, the command starts both the RAP-processing listener and the RAP-processing server.

Example of command execution:

> dcsvstart -u RAP-processing-listener-name

To stop the RAP-processing listener and RAP-processing server, execute the dcsvstop command. You can also stop the RAP-processing listener and RAP-processing server by using the dcstop command to shut down OpenTP1.

If you execute the dcsvstop command with the name of the RAP-processing listener specified as a command argument, the command stops both the RAP-processing listener and the RAP-processing server.

Example of command execution:

> dcsvstop RAP-processing-listener-name

Start up the RAP-processing listener and RAP-processing server using the user identifier of the system administrator. The RAP-processing listener and RAP-processing server create files under $DCDIR/spool and therefore a startup without the user identifier of the system administrator results in an error. This error happens because of the permission of the directory.

When the RAP-processing listener starts up, the message KFCA00327-W may appear. This is an error message to an RPC that the RAP-processing listener issues to the RAP-processing server when it executes a service function. The RAP-processing listener is set to retry even if an error occurs in the RPC. Since it is set to retry, there is no problem in the program even if the error message appears.

Do not shut down (by the dcsvstop command) or start up (by the dcsvstart command) the RAP-processing server solely. While the RAP-processing server is online, do not execute the scdhold command for the RAP-processing server. In the following cases, however, start up the RAP-processing server by using the dcsvstart command.

• When an error occurs due to a definition error
  The RAP-processing listener automatically starts up the RAP-processing server. The message KFCA00244-E does not indicate the location of the error in the system definition. If the cause code in the message KFCA01812-E is CONFIGURATION, check the definitions of the RAP-processing server. The RAP-processing listener has no way of knowing that the RAP-processing server cannot start up because of a definition error. Therefore, it outputs the message KFCA26950-I and waits for the remote API service to become ready. In this case, correct the operand of the RAP-processing server and start up the RAP-processing server by using the dcsvstart command.
  
• When the RAP-processing listener goes down while shutting down the RAP-processing listener or server
  When the RAP-processing listener goes down while shutting down the RAP-processing listener or server, the RAP-processing server may output the message KFCA26950-I and wait for the remote API service to become ready, even if the next dcsvstart command starts up the RAP-processing listener. If the RAP-processing server is not started up, execute the dcsvstart command to start up the RAP-processing server manually.
