Internet Server Application

This section provides a discussion of some of the parameters in the ZINET ADD and ZINET ALTER commands that you must consider when adding an Internet server application or subsequently changing its characteristics. See TPF Operations for more information about the ZINET ADD and ZINET ALTER commands. The USER parameter must specify one of the TPF-supplied user IDs listed in the TPF C/C++ Language Support User's Guide.

For each Internet server application, the Internet daemon either automatically starts the listener process or the operator manually starts the Internet daemon listener. Use the ACTIVATION parameter, which can be abbreviated to ACT, to specify whether listening is automatic or manual.

The Internet daemon is active starting from CRAS state, so you must decide the appropriate state in which to start your Internet server application. The STATE parameter can be specified as STATE-CRAS or STATE-NORM. Table 8 shows the interaction of the STATE and ACT parameters with the state of the TPF system.

Table 8. Relationship of STATE and ACT Parameters with the TPF System State

STATE ACT System State Comment
CRAS AUTO CRAS or NORM Internet server application is started automatically.
OPER CRAS or NORM Internet server application can be started manually.
NORM AUTO CRAS Internet server application is not started automatically and cannot be started manually.
OPER CRAS Internet server application cannot be started manually.
AUTO NORM Internet server application is started automatically.
OPER NORM Internet server application can be started manually.

Internet Server Application Control

Use the ZINET START command to allow the Internet daemon to start an Internet daemon listener process for the specified Internet server application. Use the ZINET STOP command to stop the Internet daemon from starting Internet daemon listener processes for the specified Internet server application. See TPF Operations for more information about the ZINET START and ZINET STOP commands.

Note:
After an Internet server application is added to the IDCF, use the ZINET START command to start an Internet daemon listener process for the Internet server application.
