IST1531I

Explanation
 This message is the first of a subgroup of messages
that VTAM® issues in response
to a DISPLAY SRCHINFO,SID command.
 Possible message subgroups
follow.  Note that the group will be displayed if the SID can be located,
even if no search is outstanding. This means this group will be displayed
if DISPLAY SRCHINFO,SID is issued using a SID for an active session,
for example.  If search information can be found in the subarea network, VTAM issues the following messages:
  IST350I   DISPLAY TYPE = SRCHINFO

 IST894I  This message is a header for the information displayed in message
IST895I.

 IST895I  This message is issued when adjacent SSCP routing is in progress.
An IST895I message is issued for each SSCP, in the order it was tried,
until all adjacent SSCP routing information has been displayed or
until the MAX operand value on the DISPLAY SRCHINFO command has been
reached.
sscpname is the adjacent SSCP through which
trial-and-error routing was attempted.
sense is the sense code indicating the cause
of failure.

 IST1454I  The value for count can be:  The total number of adjacent SSCPs, in decimal, displayed in the
IST895I messages.
The total number of adjacent CPs, in decimal, displayed in the
IST1538I messages.

 IST1520I  This message is a header for the subarea messages that follow.
Subarea information is provided if TYPE=SUBAREA or TYPE=ALL was specified
on the DISPLAY SRCHINFO command.

 IST1526I  This message is a header for the APPN messages that follow. APPN
information is provided if TYPE=APPN or TYPE=ALL was specified on
the DISPLAY SRCHINFO command.

 IST1531I  sid is the session ID (SID) for the session.
The session ID, also known as the procedure correlation ID (PCID),
is applicable to both APPN and subarea searches.
origcp is the name of the control point for
the LU that originated the search request.  If origcp is
ISTAPNCP, the search request was passed from the APPN component of
this host to the subarea component. In mixed environments involving
both subarea and APPN nodes, origcp could be the
name of a host involved in transferring the search request between
APPN and subarea (for example, in a subarea search initiated by a
central directory server (CDS)).

 IST1532I  oluname is the network-qualified name of the
LU that is originating the search request. If known, the OLU's real
name is shown. Otherwise, ***NA*** is shown.
dluname is the network-qualified name of the
LU that is the destination of the session request. If known, the DLU's
real name is shown. Otherwise, the DLU alias name is shown.

 IST1533I  The values for conc can be:  YES
Search is concentrated behind a scout search, attempting to locate
a specific resource.
NO
Search is not concentrated behind a scout search, attempting to
located a specific resource.

The values for rds can be:  YES
This is a resource discovery search (RDS), a type of scout search.
NO
This is not a resource discovery search (RDS).

 IST1534I  This message gives the name of the adjacent CP or SSCP (dirolu)
in the direction of the originating LU (OLU).

 IST1535I  The values for reply can be:  YES
If a positive reply was returned towards the parent CP.
NO
If a positive reply was not returned towards the parent CP.

 IST1536I  This message is issued only if CONCENTRATED=YES in message IST1533I.
conc_pcid is the procedure correlation ID
(PCID) of the scout search behind which this search is concentrated.
conc_mod is the PCID modifier of the scout
search behind which this search is concentrated.

 IST1537I  This message is issued only if CONCENTRATED = NO in message IST1533I.
It is a header message for the information displayed in message IST1538I.

 IST1538I  In the subarea message subgroup:  name is the network-qualified name of an SSCP
from which this search is awaiting a reply. If the name is ISTAPNCP,
the host is awaiting a response from a search of the APPN network.

In the APPN message subgroup:  name is the network-qualified name of a control
point from which this search is awaiting a reply. If a host appears
to be awaiting a reply from itself, as shown by name in
message IST1538I, the host is awaiting a response from a search of
the subarea network.

 IST1539I  pcidmod is the procedure correlation ID (PCID)
modifier to the PCID in message IST1531I.

 IST1540I  status is the status of the search request.
See in the z/OS Communications Server: IP and SNA Codes for list of status values.
sscpolu is the name of the SSCP originating
the search request.  Note that this might not be the CP(OLU) if the
network consists of both subarea and APPN nodes.

 IST1541I  locates is the number of Locates outstanding
for this PCID.
task is the current task being performed on
behalf of the search. The value for task can be:

search is nonzero.
nbr_conc is the number of other searches concentrated
behind this scout search.

 IST1545I  role is a hexadecimal representation of the

 IST1548I  The values for bdcst can be:  YES
A broadcast search is in progress.
NO
A broadcast search is not in progress.

The values for drctd can be:  YES
A directed search is in progress.
NO
A directed search is not in progress.

 Note: Both bdcst and drctd can
be YES at the same time (for example, a directed search from an end
node that is turned into a broadcast search by the network node server
(NNS)).

This message is only issued if CONCENTRATE = NO in message IST1533I.

 IST1704I or IST1705I  sc_option indicates a search control option
associated with the search being displayed.  Possible values are:
SORDER and SSCPORD. When VTAM is
enabled for APPN, both search control options will be displayed with
SORDER being first.  When VTAM is
not enabled for APPN, SSCPORD will be the only search control option
displayed.  Either IST1704I or IST1705I will be issued for each search
control option displayed.
sc_value indicates the value of the search
control option associated with the search being displayed.  If sc_value is
ADJLIST, the adjacent SSCP table associated with the search being
displayed is for a resource that specified an adjacent CDRM list (ADJLIST);
therefore, the SORDER and SSCPORD search control options do not apply.
