Overriding the SSCP lists

If a list of adjacent SSCPs exists for a destination network, an SSCP, or both, and if VTAM® already has an SSCP-SSCP session with the destination SSCP, session setup processing can override the list; that is, the destination SSCP becomes the first choice for the specific session request. This override is temporary and does not change the actual adjacent SSCP table that you define.

Thus, the default SSCP list (TABLE2) includes the following definition statements:

         NETWORK  NETID=NETWORK3  DESTINATION NETWORK
GWSSCP32 ADJCDRM                  DEFAULT ADJACENT SSCP LIST
GWSSCP31 ADJCDRM                   FOR NETWORK3

Assume that a cross-network SSCP-SSCP session exists between GWSSCP21 and GWSSCP31. If GWSSCP21 receives a cross-network initiate request for a session with a logical unit owned by GWSSCP31 in NETWORK3, the list of adjacent SSCPs in the table (GWSSCP32 and GWSSCP31) is reordered for this session setup as follows:

GWSSCP31
GWSSCP32

The actual table you define is unaltered.

The destination SSCP name, GWSSCP31, is available in the initiate request if the alias name translation facility or a predefined CDRSC with CDRM name is used.
