Bytes 2 and 3 contain sense-code-specific information
that indicates the specific reason for not rerouting the request.
- 0000
- No specific code applies.
VTAM® hint: A
possible cause of this sense code is an error in the CDRM definition.
- 0001
- An SSCP has attempted unsuccessfully to reroute a session services
request to its destination via one or more adjacent SSCPs; this value
is sent by a gateway SSCP or a nongateway SSCP when it has exhausted
trial-and-error rerouting.
Note: This code is used when SSCP rerouting
fails completely. The remaining codes are used for failures to reroute
to a particular SSCP. For example, they are associated with specific
SSCPs when information about a rerouting failure is displayed in the
node that was trying to reroute.
VTAM Information: When VTAM receives this sense code for a session
initiation, it continues searching through the adjacent SSCP table
until the destination LU is found or routing is exhausted.
VTAM hint: Possible causes
of this error include, but are not limited to, the following ones:
- VTAM knows which node owns
the LU but is not able to route a directed search to that node to
verify the availability of the LU. If messages IST894I and IST895I
are issued and indicate that one of the adjacent SSCPs was ISTAPNCP
with a failure sense of 087F0001, this is probably the reason for
the error.
Verify that a valid search path exists. This can be
CP-CP sessions and/or a subarea path. One possible cause of the problem
is the absence of a CP-CP session between two nodes that share an
active CP-CP capable link. If this is the case, take one of the following
actions:
- Reactivate the CP-CP session.
- Deactivate the link and reactivate it as a link that is not CP-CP
capable so that topology and routing services will know that it is
no longer available for use in directed search routing.
- There is no SSCP-SSCP session.
- The half-session control block (HSCB) count is too low in the
NCP to handle the number of sessions. A possible solution to this
problem is to code a larger value on the ADDSESS keyword of the BUILD
definition statement and regen.
- Both sides are using the same SSCP name.
- 0002
- An SSCP is unable to reroute a session services request because
a necessary routing table is not available. This means that there
is no adjacent SSCP table corresponding to the rerouting key in the
resource identifier control vector. The receiver of this value will,
if possible, try rerouting to another SSCP.
VTAM Information: When VTAM receives this sense code for a session
initiation, it continues searching through the adjacent SSCP table
until the destination LU is found or routing is exhausted.
- 0003
- This sense code is set in either of these two cases:
- A CDINIT is received from an ADJSSCP (OLU), and the CDRM statement
for the ADJSSCP (OLU) does not allow this SSCP to build a dynamic
CDRSC (CDRSC=REQ).
- An SSCP (OLU) or SSCP (INT) built a dynamic CDRSC for the DLU,
but the ADJSSCP (DLU) selected does not allow this SSCP to build a
dynamic CDRSC.
VTAM Information: When VTAM receives this sense code for
a session initiation, it continues searching through the adjacent
SSCP table until the destination LU is found or routing is exhausted.
- 0004
- Session services path error: Conflict in gateway capabilities
support.
VTAM Information: When VTAM receives this sense code for
a session initiation, it continues searching through the adjacent
SSCP table until the destination LU is found or routing is exhausted.
- 0005
- An SSCP is unable to use the gateway node specified in CDINIT
because that gateway node cannot allocate an address transform for
the intended cross-network LU-LU session.
VTAM Information: When VTAM receives this sense code for a session
initiation, it continues searching through the adjacent SSCP table
until the destination LU is found or routing is exhausted.
- 0006
- An SSCP is able to use only a subset of the alternate gateway
nodes available to it. However, for the subset that it can use, none
can provide the needed alias address pair.
VTAM Information: When VTAM receives this sense code for a session
initiation, it continues searching through the adjacent SSCP table
until the destination LU is found or routing is exhausted.
- 0007
- An SSCP is unable to reroute a session services request. One of
the session partners was defined as a real CDRSC, as well as a CDRSC
without netid. This is not allowed.
- 0008
- The adjacent SSCP does not support the requested CDINIT function
(for example, notification of resource availability or XRF).
VTAM Information: When VTAM receives this sense code for
a session initiation, it continues searching through the adjacent
SSCP table until the destination LU is found or routing is exhausted.
- 0009
- Network address not valid: NCP returned an address that was already
in use for a different session. The initiate request cannot be rerouted.
- 000A
- An SSCP is unable to reroute a session services request because
the request has been routed through the same SSCP twice.
VTAM Information: When VTAM receives this sense code for
a session initiation, it continues searching through the adjacent
SSCP table until the destination LU is found or routing is exhausted.
VTAM hint: This error can occur
during an attempt to take over a switched connection because a connection-network-capable
control point (CP) on the connection network does not have a complete
system definition. See the information about common APPN problems
in z/OS Communications Server: SNA Diagnosis Vol
1, Techniques and Procedures for more information about this session takeover
problem.
- 000B
- The DLU specified in the CDINIT is unknown to the receiving SSCP,
and the receiving SSCP cannot reroute the CDINIT.
VTAM Information: When VTAM receives this sense code for a session
initiation, it continues searching through the adjacent SSCP table
until the destination LU is found or routing is exhausted.
- 000D
- An SSCP has purged a session services request because the adjacent
SSCP did not respond to the request within a specified installation-defined
time limit.
VTAM Information:
When VTAM receives this sense
code for a session initiation, it continues searching through the
adjacent SSCP table until the destination LU is found or routing is
exhausted.
VTAM Hint:
A possible cause of this error is that the response from the CDINIT
sent toward the DLU has not been received during the operator specified
time interval. The CDINIT timed out, and a negative CDINIT response
is assumed.
- 000E
- A locate search request was limited because a prior search had
determined that the subject target resource was not currently accessible
and the search delay thresholds had not yet been met.
VTAM hint: The resource was
not found. A locate search request was limited because a prior search
had determined that the subject target resource was not currently
reachable (a valid search reduction entry exists).
