Using the NetView program for network management

The NetView® program provides facilities for problem determination and network management in a gateway configuration. These facilities include:

Information about the alias addresses, alias and real LU names, and owning SSCPs for LUs involved in cross-network sessions
Session awareness data, such as session protocols
Inquiry, on a session basis, as to whether a complete physical path exists between the controlling subarea nodes of the two session partners
Display of the subarea nodes and transmission groups

The availability of these functions for a particular cross-network session depends on the NetView program being installed in the appropriate hosts. It also depends on the appropriate level of VTAM® or NCP being installed in each subarea.

It is recommended that the NetView program be installed at every gateway VTAM host and at every host that controls resources that might have cross-network sessions. This ensures that the NetView program is able to provide the maximum amount of problem determination data for cross-network sessions.

Note: When Netview is active, some messages will be sent to the Netview instead of the MVS™ system console. See z/OS Communications Server: SNA Messages for further information about solicited and unsolicited messages and their destinations.
