The following table shows the settings for a target Datareplicator's communications environment.

Table 2-11 Settings for a target Datareplicator's communications environment

Communications environment	Settings
/etc/services	Specify the service-name and port-number to be used for communication with the source system. Specify this service name in the hdsservice operand in the import system definition. Use the same port number as for the source system.
XNF network definition	If the OSI protocol (channel connection) is used for communication#, specify the UCE name and T selector value to be used for communication with the source system. Specify this T selector value in the reflect_tselector operand of the import system definition. Use the same T selector value as for the source system.

#: The OSI protocol (channel connection) is supported only when the operating system being used is HP-UX; in the case of AIX, Linux, or Windows, only TCP/IP is supported as the communications protocol.

The following is an example of setting up a target Datareplicator's communications environment. For details about the TCP/IP network environment settings, see the HI-UX/WE2 Hitachi CSMA/CD Network CD105 (TCP/IP) manual. For details about the XNF network definitions, see the XNF/S-E2 Definition manual.

(a) Example of /etc/services for a target Datareplicator

The following is an example of specifying the service name and port number in /etc/services:

service-name port-number/tcp

Note

The underline portion is a fixed value.

service-name

Specify any name.

port-number
