Explanation
VTAM® issues
this message as part of a group of messages in response to a DISPLAY SESSIONS,
DISPLAY APING, or DISPLAY ID=rtp_pu command. See
the explanations of IST873I, IST878I, IST879I, IST1476I, and IST1489I
for a complete description of possible message groups.
This
message displays information about an adjacent SSCP (ADJSSCP),
adjacent link station (ALSNAME), or APPN Class of Service (APPNCOS).
VTAM(r)
might issue this message twice if the issuing SSCP is an intermediate
host.
adjacent_resource_type is
one of the following:
- DLU
- The adjacent SSCP is in the direction of the destination logical
unit (DLU), and a CDINIT or DSRLST is pending for the session. DLU applies
only to adjacent SSCPs.
- PLU
- The adjacent SSCP or adjacent link station is in the direction
of the primary logical unit (PLU).
- RTP
- The ALSNAME or APPNCOS is used in the direction of other endpoint
of the RTP pipe.
- SLU
- The adjacent SSCP or adjacent link station is in the direction
of the secondary logical unit (SLU).
resource_name is
one of the following:
- If ADJSSCP or ALSNAME display in this message, resource_name is
the name of the adjacent SSCP toward the indicated adjacent_resource_type.
- If APPNCOS displays in this message, resource_name is
the APPN class of service (CoS) name.
text is not displayed when:
- The resource described in this message is an adjacent link station.
- The SSCP is not gateway capable.
- The SSCP-SSCP session is a cross-domain session.
- An APPN Class of Service name is displayed.
Possible values are:
- GWNCP NAME NOT AVAILABLE
- The gateway NCP name is not known to VTAM(r).
- GWNCP TOWARDS gateway_type = gwncp
- The gateway NCP name is known to VTAM(r).
Possible values
are:
- DLU
- The gateway NCP is toward the DLU. VTAM(r) issues DLU only
if adjacent_resource_type is DLU.
- PLU
- The gateway NCP is toward the PLU.
- SLU
- The gateway NCP is toward the SLU.
gwncp is the gateway NCP
toward the pluname or sluname in
message IST874I.
