Multiple-domain support routing exception: The MDS router in the
reporting NAU is unable to perform the required routing for an MDS-MU.
When this SNA report code is used in an SNA condition report (X'1532')
GDS variable, the destination NAU name is included in the reported
on location name (X'09') subvector and the destination MS
application name is included in the reported on agent (X'04')
subvector of the condition report.
Bytes 2 and 3 following the sense code contain sense-code-specific
information.
- 0000
- No specific code applies.
- 0001
- Destination NAU name unknown. Directory services could not
locate the requested destination name.
- 0002
- Directory services unavailable. No routing possible.
- 0003
- MS application program name not recognized.
- 0004
- Use of CPSVCMG session not permitted. The reporting network
node has received an MDS-MU over a CPSVCMG session from another network
node. These sessions are used for MDS-MUs only between a network node
and its served end nodes.
- 0005
- Function not supported by EN destination. The back-level end
node destination does not support receipt of MS messages (reported
by serving network node).
- 0006
- Function not supported by destination. The back-level destination
does not support receipt of MS messages other than MS Capabilities
and Alert.
- 0007
- Function not supported by serving NN. The serving network node
of the end node destination does not support routing of MS messages
(reported by network node performing routing).
- 0008
- Function not supported by EN. The reporting end node has received
an MDS-MU with a destination other than itself.
- 0009
- Destination not supported by reporting NN. A network node has
received an MDS-MU from another network node that cannot be routed.
The destination is not the reporting network node itself nor is it
one of the served end nodes.
If the MDS-MU was routed based on
nonverified directory information (as indicated by the routing verification
indicator in the MDS routing information), the MDS-MU will be returned
to the routing network node along with the SNA condition report.
- 000A
- Unrecoverable session failure. The MDS_SEND TP in the reporting
node was unable to send the message because of an allocation error.
Retries have been exhausted.
- 000B
- Unrecoverable TP failure in remote node. The MDS_SEND TP in
the reporting node was unable to send the message because of a TP
failure in a remote node. Retries have been exhausted.
- 000C
- MS application program failure. The MDS router in the destination
NAU is unable to communicate with the destination MS application program.
- 000D
- Unrecoverable TP failure in reporting node. The MDS router
in the reporting node was unable to send the message because of a
local TP failure.
- 000E
- Correlation error. An MDS-MU has been received that is not
the first for a unit of work (first MDS message indicator in the MDS
routing information message is zero), but the agent unit of work correlator
is unknown (does not match any active MDS transaction). Also used
to report the receipt of a duplicate correlator (MDS-MU with first
MDS message indicator is one, but the agent unit of work correlator
matches one currently in use).
- 000F
- MS application program congestion. The MDS router in the destination
NAU is unable to communicate with the destination MS application program
because of local congestion (implementation buffer space for queuing
additional MDS-MUs has been exhausted).
- 0011
- MDS HPO not supported by MS application program. The destination
MS application program does not support the use of the MDS high performance
option.
- 0012
- Unrecoverable failure of user-mode session. MDS has detected
an error on a user-mode session (a user-mode session in this context
is one with a mode name other than SNASVCMG or CPSVCMG). Retries have
been exhausted. Application program data might have been lost.
- 0013
- Session UNBIND notification. The last session to the indicated
destination has been deactivated. See product documentation for additional
information.
