API Signons
The communication address used to establish a connection to IBM® Connect:Direct® is determined by the TRANSPORT parameter defined in the SIGNON command. The default for the TRANSPORT parameter is NET (NETMAP), which means that the protocol defined in the NETMAP adjacent node entry is used.
| Parameter Value | Description |
|---|---|
| TRANSPORT = NET | Default. When TRANSPORT is defined as NET, the
signon process retrieves the adjacent node entry to determine if the
TCPAPI parameter has been defined. If TCPAPI exists, then a TCP connection
is attempted using the communications address defined. The communications
port number is obtained from the TCPAPI parameter, and if the IP address
exists in the TCPAPI parameter, it is also used. If the IP address
does not exist in the TCPAPI parameter, it must be obtained from either
the adjacent node or the LDNS parameter. If the TCPAPI does not exist, the APPLID parameter is retrieved, and SNA is used as the protocol. |
| TRANSPORT = SNA | When TRANSPORT is defined as SNA, the signon process retrieves the adjacent node entry to determine the APPLID parameter, and SNA is used as the protocol. If the APPLID parameter does not exist, then an ESF SIGNON is performed. |
| TRANSPORT = TCP | When the TRANSPORT is defined as TCP, the communications
address must be specified on the SIGNON command. To initialize IBM Connect:Direct without SNA support, refer to Initializing IBM Connect:Direct without SNA Support in the IBM Sterling Connect:Direct for z/OS® Configuration Guide. |
