Explanation
This message is the first in a group of messages
that VTAM® issues when the COS
table name (defined by the COSTAB operand) or the maximum subarea
value (defined by the MAXSUBA operand) on the BUILD or NETWORK definition
statement could not be defined to VTAM.
A complete description of the message group follows.
IST1035I ERROR WHILE {ADDING|DELETING} NETWORK netid {TO|FROM} GWN gatewaynode
IST523I REASON = reason
IST1035I - netid is the dynamic network to which a connection
was attempted. When gatewaynode is activated,
this statement is processed. For gateway nodes, this is a model network
statement.
- gatewaynode is the gateway node for which network netid could
not be added or deleted.
IST523I - reason indicates the reason for the failure,
and is one of the following:
- COSTAB NOT FOUND
- The COS table name associated with a model network could not be
found when VTAM attempted to
add network netid.
- COSTAB USE COUNT OVERFLOW
- VTAM has exceeded its ability
to record gatewaynode’s sharing of the COS
table coded on the COSTAB operand.
- DUPLICATE COSTAB
- The COS table for netid and for gatewaynode has
already been defined on a BUILD or NETWORK definition statement for gatewaynode.
- DUPLICATE MAXSUBA
- The maximum subarea value (MAXSUBA) has already been defined on
a BUILD or NETWORK definition statement for gatewaynode or
another gateway node.
- DUPLICATE SUBAREA
- The subarea value has already been defined on a BUILD or NETWORK
definition statement for another gateway node.
- INSUFFICIENT STORAGE
- Network netid cannot be added or deleted because
of insufficient storage.
- INSUFFICIENT STORAGE TO DEFINE COSTAB
- The COS table name (COSTAB) cannot be defined because of insufficient
storage.
- INSUFFICIENT STORAGE TO DEFINE MAXSUBA
- The maximum subarea value (MAXSUBA) cannot be defined because
of insufficient storage.
- INSUFFICIENT STORAGE TO DEFINE SUBAREA
- The subarea cannot be defined because of insufficient storage.
- MAXSUBA USE COUNT OVERFLOW
- VTAM has exceeded its ability
to record gatewaynode’s sharing of the maximum
subarea value coded on the MAXSUBA operand.
- MODEL NETWORK NOT FOUND
- The model network coded on the NETWORK definition statement with
COPIES= was not defined for gatewaynode.
- UNEXPECTED RETURN CODE
- An unexpected return code was found while adding or deleting network netid.
- UNEXPECTED RETURN CODE DEFINING COSTAB
- An unexpected return code was found while defining the COS table.
- UNEXPECTED RETURN CODE DEFINING MAXSUBA
- An unexpected return code was found while defining the maximum
subarea value.
- UNEXPECTED RETURN CODE DEFINING SUBAREA
- An unexpected return code was found while defining the subarea
value.
- UNEXPECTED RETURN CODE DELETING COSTAB
- An unexpected return code was found while deleting the COS table.
- UNEXPECTED RETURN CODE DELETING MAXSUBA
- An unexpected return code was found while deleting the maximum
subarea value.
- UNEXPECTED RETURN CODE DELETING SUBAREA
- An unexpected return code was found while deleting the subarea
value.
System action
If this message was issued because network netid could
not be added, all cross-network sessions destined to network netid will
fail except for SSCP-SSCP sessions and for LU-LU sessions that use
the default blank COS entry.
The system action depends on the
value of
reason:
- COSTAB NOT FOUND
- Network netid is ignored for gatewaynode.
- COSTAB USE COUNT OVERFLOW
- The COS table name is ignored. Even though the Class of Service
table is defined for other active NCPs, it still cannot be used for
this NCP definition, since its usage cannot be recorded to VTAM.
- DUPLICATE COSTAB
- The COS table name is ignored. The original COS table name for
the NETID defined in this NCP definition is used.
- DUPLICATE MAXSUBA
- The maximum subarea value is ignored. A different value has already
been defined successfully to this host, and cannot be changed or redefined
for the network identified by the coded NETID until all networks that
depend on this maximum subarea value are deactivated.
- DUPLICATE SUBAREA
- The subarea name is ignored. The original subarea name for the
NETID defined in this NCP definition is used.
- INSUFFICIENT STORAGE
- Network netid cannot be added or deleted because
of insufficient storage. Processing continues.
- INSUFFICIENT STORAGE TO DEFINE COSTAB
- The COS table name is ignored.
- INSUFFICIENT STORAGE TO DEFINE MAXSUBA
- The maximum subarea value is ignored. If this host resides in
the gateway NCP’s native network, and will own links or link
stations in the network identified by the NETID operand, it will be
impossible to activate those links or link stations without knowledge
of that network’s maximum subarea value. However, if the definition
of another NCP has successfully defined the maximum subarea for the
network, such link and link station activations will be possible,
as long as that other NCP is not deactivated.
- INSUFFICIENT STORAGE TO DEFINE SUBAREA
- The subarea name is ignored.
- MAXSUBA USE COUNT OVERFLOW
- The maximum subarea value is ignored.
- MODEL NETWORK NOT FOUND
- The definition of network netid fails.
- UNEXPECTED RETURN CODE
- The definition of network netid fails.
- UNEXPECTED RETURN CODE DEFINING COSTAB
- The COS table name is not defined.
- UNEXPECTED RETURN CODE DEFINING MAXSUBA
- The maximum subarea value is not defined.
- UNEXPECTED RETURN CODE DEFINING SUBAREA
- The subarea value is not defined.
- UNEXPECTED RETURN CODE DELETING COSTAB
- The COS table name is not deleted.
- UNEXPECTED RETURN CODE DELETING MAXSUBA
- The maximum subarea value is not deleted.
- UNEXPECTED RETURN CODE DELETING SUBAREA
- The subarea value is not deleted.
Operator response
- If text is COSTAB NOT FOUND, DUPLICATE COSTAB,
or COSTAB USE COUNT OVERFLOW, enter a DISPLAY COS,ORIGIN=gatewaynode,NETID=*
command, and save the system log for problem determination.
- If text is INSUFFICIENT STORAGE…,
deactivate all links to network netid, then reactivate
those links later when more storage is available. Enter a DISPLAY BFRUSE
command. Issue the DISPLAY STORUSE command to display storage usage
for storage pools. Save the system log and request a dump for problem
determination.
- For all other reasons, save the system log
for problem determination.
System programmer response
- COSTAB NOT FOUND
- Review the output from the DISPLAY COS command and contact the IBM® software support center.
- COSTAB USE COUNT OVERFLOW
- Review the output from the DISPLAY COS command. Restrict the usage
of the COSTAB name for each network and NCP to less than 256. If many
NCPs need to be active simultaneously, use different COSTAB names,
each defining COSTABs for many other networks. Use the MODIFY TABLE
command to correct problems.
- DUPLICATE COSTAB
- Identify the COSTAB name coded for the same NETID by reviewing
all the BUILD and NETWORK definition statements preceding the definition
statement specified for the indicated network, netid.
Code only a single COSTAB name for any one network in this NCP definition.
Use the MODIFY TABLE command to correct problems.
- DUPLICATE MAXSUBA
- Check to determine whether the maximum subarea value specified
on the MAXSUBA keyword for the BUILD or NETWORK definition statement
for the indicated NETID start option, netid is
valid. This value must also be identical to the maximum subarea values
on all other BUILD or NETWORK definition statements in this or another
NCP definition that have ever been activated.
- DUPLICATE SUBAREA
- Check all the BUILD and NETWORK definition statements preceding
the definition statement specified for the indicated network to identify
the subarea value coded for the same NETID. Code only a single subarea
value for any one network in this NCP definition. Be sure to check
all definition statements that are active.
- INSUFFICIENT STORAGE…
- It may be necessary to cancel nonessential jobs or deactivate
an unused part of the network to prevent further losses. You might
have to halt and restart VTAM if
there are too many failures.
You might want to redefine your buffer
pool or CSA limits. If the start option cannot be modified using the
MODIFY VTAMOPTS command, you must modify the VTAM start options file (ATCSTR
xx)
and restart VTAM to use the
start option.
- MAXSUBA USE COUNT OVERFLOW
- Contact the IBM software
support center.
- MODEL NETWORK NOT FOUND
- This error can be caused in one of two ways:
- The NCP was generated with a definition statement that included
a model network, but the model network was removed before the definition
was activated by VTAM. If
this is the case, restore the model network and activate the corrected
definition statement.
- There is an error in the NCP that is causing it to generate requests
for no reason. Contact the IBM software
support center.
