Notes:

SORDER is meaningful only in an interchange node or a migration data host.

Controls the order in which the APPN and subarea networks are searched when a network search request is received from the subarea network. This search order may be overridden if the target LU's location is already identified and SSCPORD=PRIORITY is specified. SORDER is valid only for network nodes (NODETYPE=NN) functioning as interchange nodes, and end nodes functioning as migration data hosts. For further information on the interaction of the SORDER start option with other start options, see the z/OS Communications Server: SNA Network Implementation Guide.

You can change the value of SORDER with the MODIFY VTAMOPTS command while VTAM® is running.

For more granular control over the search order, a different SORDER can be specified for each individual adjacent SSCP table. For more information, see Adjacent SSCP table.

See cdrmname for related information on network searches.

SORDER=ADJSSCP: Specifies that the search should be conducted based on the order coded in the adjacent SSCP table. If you specify SORDER=ADJSSCP, the APPN network is not searched unless you also coded the operand ISTAPNCP as one of the entries within the adjacent SSCP table.
SORDER=APPN: Specifies that searching the APPN network is preferred, regardless of whether (or where) the operand ISTAPNCP is coded in the adjacent SSCP table. However, the owning CDRM, the predefined owning CDRM, and any previously successful adjacent CDRMs (if SSCPORD=PRIORITY is specified), if known, are searched before the APPN network.
SORDER=APPNFRST: Specifies that the APPN network is to be searched first, without regard to whether (or where) the operand ISTAPNCP is coded in the adjacent SSCP table, or whether the owning CDRM, the predefined owning CDRM, or any previously successful adjacent CDRMs are known.
Note: SORDER=APPNFRST and SSEARCH=APPNFRST are meaningful only on Network Nodes. If SSEARCH=APPNFRST is coded on an EN, it will prevent finding resources on the EN's domain.
SORDER=SUBAREA: Specifies that the subarea network is to be searched first, regardless of whether (or where) the operand ISTAPNCP is coded in the adjacent SSCP table.
