Resource not available: The LU, PU, link station, or
link specified in an RU is not available.
Bytes 2 and 3 following the sense code contain sense-code-specific
information.
- 0000
- No specific code applies.
VTAM® hint: Possible
causes of this error include, but are not limited to, the following
ones:
- A CINIT request fails because an application rejects a terminal
log on. Message IST663I is displayed when this error occurs, and the
logon from the terminal fails with USSMSG07. See the information about
common subarea network problems in z/OS Communications Server: SNA Diagnosis Vol
1, Techniques and Procedures for more information about this problem.
- The logmode is incorrect.
- The major node is not active for the resource. (A frequent reason
for this error is that the NCP has not been activated.)
- The line is inactive.
- The line is a CALL=INOUT line over which simultaneous connections
are being attempted (dial-in and dial-out). This is a temporary
condition and the session might be tried again.
- APPC=YES was coded on the APPL definition, and there is an attempt
to establish the session using OPNDST.
- With NTRI, this error can occur when DIALNO is incorrect.
- For IMS™, the LU might not
be defined.
- 0001
- Independent LU does not receive ACTLU: An ACTLU has been sent
by the SSCP to an independent LU (sent by BF).
- 0002
- Reserved resources requested for sessions exceed allowable maximum:
The resource reservation request in RNAA exceeds the maximum allowed
by system definition. The address was not assigned and no change
was made to the current reservation of resources for the LU.
- 0003
- Name aliasing cannot be performed because the name alias function
is not available.
- 0004
- A switched connection currently exists for the link being activated,
and the SSCP or the subarea PU does not support the protocols necessary
to allow takeover of such a link.
- 0005
- A SETCV has been received for a resource that is still represented
in the pool of available control blocks.
- 0006
- The line is not associated with a line adapter, or the line is
associated with a line adapter that is not valid for the genned usage
tier.
- 0007
- The line is associated with a line adapter that is not installed
or not attached to the CCU.
- 0008
- The line is associated with a line adapter that is inoperative.
- 0009
- The LU is not available because it is not ready to accept sessions.
- 000A
- The PLU is not available because it is being taken down or has
issued SETLOGON with the OPTCD=QUIESCE. The PLU is, therefore,
not accepting new sessions. The initiation request should not
be tried again.
VTAM hint: If
the PLU is TSO, then it is likely that the TSO USERMAX limit
has been reached. If a MODIFY TSO,USERMAX=0 was issued, then
all LOGON attempts for TSO will fail with this sense code.
- 000B
- The PLU is not available because it is unable to comply with the
PLU-SLU role specification.
- 000C
- The SLU is not available because it is unable to comply with the
PLU-SLU role specification.
- 000D
- The LU is not available because its SSCP is in the process of
being taken down, and is therefore not allowing new sessions
to be started. The initiation request should not be tried again.
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 a dynamic application
program is trying to open its ACB at the same time its SSCP is in
the process of being taken down.
- 000E
- The LU is not available because an intermediate gateway SSCP is
in the process of being taken down, and is therefore not allowing
new sessions to be started.
- 000F
- The SLU is not available because it is being taken down, and is
therefore not accepting new sessions. The initiation request
should not be tried again.
- 0010
- A switched subarea connection cannot be established because no
switched subarea links are defined.
- 0011
- Switched subarea connection to another network cannot be established
because no switched subarea links are defined within a gateway NCP.
- 0012
- An APPN connection cannot be established because this node has
no available integers to represent a new TG.
- 0013
- Switched connection cannot be established because a SHM GROUP
was not defined in the switched PU's PATH definitions.
- 0014
- A switched connection cannot be established. Call request verification
was requested, but is not supported for this configuration. This condition
results from conflicting system definition.
- 0015
- The link connection is unavailable as a result of a hardware failure
within the line adapter.
- 0016
- A link resource is not available as a result of maintenance occurring
on the supporting hardware.
- 0017
- A link resource is not available because a mismatch exists within
the microcode of the supporting hardware.
- 0018
- Activation of the channel link failed because the supporting hardware
is undergoing error recovery.
- 0019
- Activation of the channel link failed because the supporting hardware
is undergoing concurrent maintenance.

- 001F
- A link connection is associated with a protocol that is inoperative.
- 0020
- A link resource is not available because of a mismatch between
current operational parameters and the values specified at system
generation.
- 0026
- The PU is not available because the dependent LU server-dependent
LU requester connection could not be established.
- 0027
- A switched connection cannot be established because no switched
link has been defined.
VTAM hint: A
switched connection cannot be established because a GROUP was not
defined in the switched PU's PATH definitions or the defined GROUP
does not exist in any active NCP major node.
- 0028
- REQDACTPU was received for a PU that is known but whose SSCP-PU
session is currently inactive.
- 0029
- A multipath channel connection cannot be established because the
system level is not at least MVS™ 4.3.
- 002A
- An ACTLINK has been received for a resource that is still represented
in the pool of available control blocks.
- 002B
- Resource is unavailable due to program or operator action. This
sense code is returned by the DLU network node server when it performs
resource verification reduction for a DLU in its domain which has
registered itself as unavailable for an unexpired time.
- 002C
- The required extended coupling facility is not available.
- 002E
- Generic Resource
exit indicated to fail this session.
