Using a VTAM application program to manage the network
VTAM® provides two independent facilities through which properly authorized application programs can manage a network. With the first facility, a program operator application program can issue most of the VTAM operator commands and can receive VTAM messages normally delivered to a VTAM operator console. VTAM language, describes the SENDCMD and RCVCMD macroinstructions. Refer to Program operator coding requirements, for information on program operator coding requirements.
With the second facility, an authorized application program can use the communication network management (CNM) interface. Such an application program can collect data related to SNA sessions from VTAM and NCP, collect maintenance-related information from a PU, or load a PU type 2 within its domain. This capability, described in Coding for the communication network management interface,
