Explanation
This message is part of a group of messages that VTAM® issues in the following situations: 
When duplicate session information is received during SSCP takeover
processingThe first message in this message group is IST1419I.
See the explanation of that message for a complete description.

 is specified.A complete description of the message group follows.  IST350I  DISPLAY TYPE = SESSIONS

Notes: Information about sessions with unknown partners is not provided
by the DISPLAY SESSIONS command. If this information is needed, enter
a DISPLAY ID command for the known session partners.
Messages IST1161I and IST1162I are only displayed when information
about all active sessions is requested. If specific sessions are requested
using the PLU, SLU, LU1, LU2, or SID operand on the command, messages
IST1161I and IST1162I are not displayed.
See z/OS Communications Server: SNA Operation for a description of the DISPLAY SESSIONS
command.

IST350I  This message identifies the type of information shown in the
display. For this message group, the display type is always SESSIONS.

IST873I  This message is a header message for the information displayed
in message IST874I.

IST874I  pluname is the network-qualified primary session
partner name.
sluname is the network-qualified secondary
session partner name.
sessionid is the session identifier. For additional
information on the session, enter a DISPLAY SESSIONS,SID=sessionid command.
status is the session status. See the z/OS Communications Server: IP and SNA Codes for a description of possible session initiation
and termination states.

Note: If the display shows the same session twice with
two different values of       status, both LOCATE
and BIND processing for the session might be occurring      simultaneously.
This situation should last for only a short time. Try the DISPLAY
SESSIONS      command again. If the session still appears twice, there
might be a hung session.

IST875I  This message displays information about an adjacent SSCP (ADJSSCP)
or adjacent link station (ALSNAME).
VTAM 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 the name
of the adjacent SSCP toward the indicated adjacent_resource_type.
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.

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.

IST878I
This message displays
the number of PENDING, ACTIVE, QUEUED, and TOTAL sessions.
count is
the number of sessions of a specified type.
Notes: If the value of the MAX operand is exceeded, count displays **********. 
If LOCATE and BIND processing for a session is occurring simultaneously, count includes
both sessions.

IST1154I  This message is displayed when name in message
IST1364I is a generic resource name.
resourcename is a logical unit or an application
in the form netid.name.

IST1161I  This message is a header message for IST1162I. The IST1161I and
IST1162I subgroup is displayed when active SSCP-LU and SSCP-PU sessions
and active and pending active SSCP-SSCP sessions exist.

IST1162I  This message is issued when active or pending active sessions
exist.  If all active sessions are requested, this message follows message
IST878I and displays the number of active LU-LU and CP-CP sessions
(CONWINNER and CONLOSER).  Note: If the value of the MAX operand is
exceeded, count for the LU-LU sessions displays **********.
count for CP-CP
CONWINNER and CP-CP CONLOSER is usually the same. If these
numbers are different, VTAM(r) is in the process of bringing up the
session or taking it down. No user action is needed.

If all active sessions are requested, this message follows header
message IST1161I and displays active SSCP-LU and SSCP-PU sessions
and active and pending active SSCP-SSCP sessions. count for
SSCP-SSCP sessions also includes pending sessions. count in
message IST878I for ACTIVE and TOTAL sessions does not
include these sessions.  The value of count for active SSCP-LU sessions
includes two VTAM-initiated sessions with the ISTNOP and ISTPDCLU
applications.
The value of count for SSCP-SSCP sessions includes
both pending and active sessions.

If specific sessions are requested using the PLU, SLU, LU1, LU2,
or SID operand on the command, this message is not displayed.

IST1237I  This message is issued for PENDING and QUEUED sessions
only, and displays status information. If count is 0,
message IST1237I is not displayed.
state is the state of the session. See the z/OS Communications Server: IP and SNA Codes for a description of possible session initiation
and termination states.
number is the number of sessions in the specified state.

IST1364I  This message is displayed when name is a generic
resource name. It serves as the header message for message IST1154I.
name is the generic resource name for the
group of resources displayed.
