You can use the alias function of the session management exit routine to perform name translation. By using this exit routine, you can provide your own alias and real names for logical units, logon mode names, Class of Service names, and SSCP names, instead of using the NetView® alias name translation definitions. You can also indicate whether the NetView alias name translation facility is to be invoked for additional translation.

The session management exit routine can be invoked to translate a real or alias logical unit name associated with one network to a real or alias logical unit name for the destination network. You can map different LOGMODE and COS names in different networks to be functionally equivalent, and can also provide directory services by providing the owning SSCP names for the destination resource.

If you are using the NetView alias name translation facility, you can selectively invoke it to perform additional translations not performed in the exit routine. When the exit is invoked, there is an indicator that informs you if the NetView alias name translation facility is currently active. The exit routine can determine whether the session requests should be rejected, depending on the need for further translation by the NetView alias name translation facility and whether it is active. It can also accept or reject the use of a substitute COS.

For information about using the alias selection function of the session management exit routine, see z/OS Communications Server: SNA Customization.
