OS/400 Registration Facility

Exit points for TCP/IP applications are automatically registered when the parent product or option is installed, using the OS/400 registration facility. The registration facility contains a repository that allows customers to associate their exit programs with specific exit points. TCP/IP applications check the registration facility repository to determine which exit program to call for a particular exit point.

You must add your exit program to an exit point in the registration repository before a TCP/IP application can call it. Adding the exit program to the repository associates the exit program with a specific exit point.

For security exit programs, the TCP/IP application will typically request the exit program to indicate if a specified operation should be allowed. When no exit program has been added to an exit point, the TCP/IP application assumes that no additional security controls are to be applied.

You can use the Work with Registration Information (WRKREGINF) command to display a list of the exit points in the OS/400 registration facility. Use this list to display information about an exit point or to work with exit programs associated with an exit point. The Work with Registration Information display is shown in Figure 63 on page 82.

TCP/IP Application Exit Points

The following table lists the exit points provided for each TCP/IP application.

Note: If using Distributed Data Management (DDM), see the DDMACC parameter on CHGNETACMD in Control Languages (http://publib.boulder.ibm.com/pubs/html/as400/v5r1/ic2924/info/rbam6/ rbam6clmain.htm) for more information. If you are using the Supplemental Manuals CD, then switch to the iSeries Information Center CD to access this information.
