Specifies the way VTAM® locates a DLUR PU when the connection is initiated by the DLUR. If you do not code DLRORDER, VTAM searches for a DLUR PU by the station identifier (IDBLK and IDNUM operands on the PU definition statement for the switched major nodes) first. If VTAM does not find the PU by the station identifier (STATNID), it searches for the DLUR PU by CPNAME since the second parameter defaults to FIRST.
If the second parameter is defined as ONLY, the search using CPNAME will not be done. If the PU is not found using STATNID, and dynamic PUs are allowed, a dynamic PU will be created and connection processing will continue. If dynamic PUs are not allowed, the PU connection processing will fail.
You can change the value of DLRORDER with the MODIFY VTAMOPTS command while VTAM is running.
Tip: Some DLURs have the capability of sending the PU name to the DLUS. In this case, the DLUS VTAM tries to find the PU by name before looking for the PU by CPNAME or station ID, and the DLRORDER setting is ignored. Refer to the DLUR implementation procedures to see if this function is supported.
- value_1=CPNAME
- Specifies that VTAM searches for a DLUR PU by the CPNAME.
- value_1=STATNID
- Specifies that VTAM searches for a DLUR PU by the station identifier (default).
- value_2=FIRST
- If a switched PU is not found using the value specified by value_1, the alternate value of value_1 will be used to search for a switched PU.
- value_2=ONLY
- If a switched PU is not found using the value specified by value_1, a search using the alternate value of value_1 will not be performed.
