Explanation
VTAM® issues
this message when the DYNLU value associated with an adjacent node
is set. DYNLU specifies whether cross-domain resources (CDRSCs) using
adjacent link stations (ALS) attached to the adjacent node can be
defined dynamically. The DYNLU value for an adjacent node will be
set from one of the following:
- The DYNLU keyword on the corresponding ADJCP definition statement
in a predefined adjacent control point (ADJCP) major node.
- The CDRSC keyword on the corresponding CDRM definition statement
in a cross-domain resource manager (CDRM) major node, when the first
connection activated to the adjacent node is a virtual route transmission
group (VRTG).
- The DYNLU keyword, if specified, on the first PU used to establish
a connection from this node to the adjacent node, when the first connection
activated to the adjacent node is not a VRTG.
- The DYNLU start option if the DYNLU value is not obtained elsewhere.
The DYNLU value is associated with an adjacent APPN
node when the first link to that adjacent node is activated. When
the DYNLU value is associated with the adjacent node, that value will
be propagated to all APPN links to the adjacent node as they are activated,
regardless of the DYNLU value specified for each link. See the DYNLU
Combinations table in the description of the adjacent
control point major node DYNLU operand in z/OS Communications Server: SNA Resource Definition
Reference for information about how to determine the
source of the DYNLU value assigned to an adjacent CP and attached
resources.
In the message text:
- dynlu_value
- The DYNLU value associated with the adjacent node, adjacent_node,
which will be propagated to all resources attached to the adjacent
node. The dynlu_value value can be one of the
following:
- YES
- Specifies that dynamic definition of CDRSCs is allowed for sessions
to or through this adjacent node. You are not required to predefine
resources that use adjacent link stations attached to the node indicated
by the adjacent_node value.
- NO
- Specifies that dynamic definition of CDRSCs is not allowed for
sessions to or through this adjacent node. You must predefine resources
that use adjacent link stations attached to the node indicated by
the adjacent_node value. If you do not predefine
the resources, session requests for sessions with the node indicated
by the adjacent_node value will fail with sense
code 08970015 or 08970016.
See sense
code 08970015 or sense code 08970016 in z/OS Communications Server: IP and SNA Codes for more information.
- adjacent_node
- The network-qualified CP name of the adjacent node.
- source
- The source of the DYNLU value being associated with the adjacent_node.
Possible values are:
- ADJCP
- Specifies that the DYNLU value associated with the adjacent node,
which will be propagated to all resources that attach to that adjacent
node, was learned from a predefined ADJCP definition statement in
an ADJCP major node.
- CDRM
- Specifies that the DYNLU value associated with the adjacent node,
which will be propagated to all resources that attach to that adjacent
node, was learned from the CDRSC keyword on a predefined CDRM definition
statement for that adjacent node in a CDRM major node. The DYNLU
value is learned from a CDRM definition statement when the first connection
activated to that adjacent node is a VRTG.
- puname
- The name of the first PU that connects to the adjacent node value,
when no predefined ADJCP exists for that adjacent node, or a predefined
ADJCP without DYNLU specified exists for the adjacent node. If a
DYNLU value is specified on the PU definition for the PU specified
by the puname value, it is the source of the DYNLU
value being associated with the adjacent node. Otherwise, the DYNLU
start option value is associated with the adjacent node and set in
the PU.
System action
Operator response
Programmer response
If the DYNLU value for the adjacent node
is not the setting that you want, do the following to reset the value
for this adjacent node:
- If an ADJCP major node exists with an ADJCP definition for the
adjacent node, without DYNLU specified or with DYNLU specified
with the incorrect value, first deactivate the ADJCP major node.
- To ensure predictable results, you should code the desired DYNLU
value on the ADJCP definition statement for the adjacent node in an
ADJCP major node. See the adjacent control
point major node information in z/OS Communications Server: SNA Resource Definition
Reference for more information about coding an ADJCP.
- Deactivate all PU connections, VRTG (CDRM) connections, and the
CP-CP sessions to the adjacent node.
- Enter a DISPLAY NET,RTPS,CPNAME=adjacent_node and
make sure there are no RTPs active to the adjacent node. If active
RTPs to the adjacent node exist, they must be deactivated. See
the DISPLAY RTPS command in z/OS Communications Server: SNA Operation for more information about this command.
- Activate the ADJCP major node.
- Reactivate the desired PU connections, VRTG (CDRM) connections,
and the CP-CP sessions to adjacent_node.
