This message is the first in a group of messages that VTAM® issues in response to a DISPLAY ID command for an external cross-domain resource manager. A complete description of the message group follows. This group of messages might also appear as a part of another group of messages.

 IST638I  ADJNETSA = adjnetsa, ADJNETEL = adjnetel
 IST675I  VR = vr, TP = tp
 IST639I  GWN = gwn, ADJNET = adjnet
 IST640I  hostname ADDR IN ADJNET - SA = hostsa, EL = hostel

IST638I

• Message IST638I indicates the subarea address, adjnetsa, and the element address, adjnetel, of the external CDRM as defined in the adjacent network. If these addresses are unknown, this message will not appear in the display.

IST675I

• Message IST675I indicates the virtual route number (vr) and the transmission priority (tp) of the CDRM session in the adjacent network. VTAM issues this message only if the route information in the adjacent network is known.

IST639I

• Message IST639I indicates the gateway NCP name, gwn, used on the path to the CDRM in the adjacent network, adjnet. VTAM issues this message only if the gateway NCP name and adjacent network name are both known.

IST640I

• Message IST640I indicates the name of your host, hostname, its subarea address, hostsa, and its element address, hostel, as defined in the external CDRM’s network. If the name and address are unknown, this message will not appear in the display.

IST641I

• Message IST641I is a header line identifying the gateway path selection list that follows. The gateway path selection list is a list of alternate gateway NCPs used in establishing the cross-network SSCP-SSCP session (that is, the session between your host CDRM and an external CDRM in an adjacent network). If status does not appear, then messages IST642I and IST643I will follow with a list of gateway NCPs. If status is DOES NOT EXIST, then no gateway NCP is defined for the CDRM and messages IST642I and IST643I will not appear.
• Each entry in the list contains parameters used to select a particular gateway NCP for establishing the session. Once a session is active, other messages identify the path used to establish the SSCP-SSCP session.

IST642I and IST643I

• Message IST642I is a header line for the data displayed in message IST643I. The information displayed by message IST643I is obtained from the operands defined on the GWPATH definition statement in the CDRM major node. VTAM issues message IST643I for each GWPATH definition statement. If any of the information in the display is missing, the corresponding value was omitted from the GWPATH definition statement.

The information includes:

adjnet

The network identifier of the adjacent network

gwn

The name of the gateway NCP used on the path to the CDRM

adjsa

The subarea address of the CDRM as defined in your network

el

The element address of the CDRM as defined in your network

adjnetsa

The subarea address of the CDRM as defined in the adjacent network

adjnetel

The element address of the CDRM as defined in the adjacent network
