ALSREQ

Specifies a list of adjacent link station names that VTAM® can use to gain session connectivity to the independent LU you are defining. The adjacent link station might be currently defined. Validation of the names occurs during session activation.

You can include ISTAPNPU in the list instead of a real adjacent link station name. ISTAPNPU is a generic representation for an APPN adjacent link station. If VTAM finds ISTAPNPU in the adjacent link station list for an independent LU, VTAM treats ISTAPNPU as if it were a real APPN adjacent link station when trying to determine whether to attempt routing through the APPN network.

If ALSREQ=YES, all session requests for this independent LU must be received over an adjacent link station that matches one in the adjacent link station list. For a LEN adjacent link station, the names must be the same to be considered a match. For an APPN adjacent link station, if any other APPN adjacent link station is in the adjacent link station list (including ISTAPNPU) it is considered a match.

Note: For a LEN adjacent link station, the NETID must match the NETID value of the independent LU at session establishment. You are responsible for ensuring that PUs named in an adjacent link station list have NETIDs that correspond to the independent LU resource. An APPN adjacent link station has no such restriction.

There might be special ALSLIST requirements for certain migration configurations involving LEN connections. See z/OS Communications Server: SNA Network Implementation Guide for details.
