IST1260I
type TRUNCATED–INSUFFICIENT STORAGE

Explanation

This message is the first in a group of messages that VTAM® issues when a lack of storage prevents VTAM from creating a complete internal representation of the specified resource type. It is also issued as a stand-alone message when a lack of storage prevents VTAM from allocating a larger trace table for TRS topology or route traces.

The message is issued alone when one 40 KB buffer of storage for the TRStopology table or route trace table is full and an attempt is made to allocate an additional buffer of storage for TRS trace table entries.

A complete description of the message group follows the example. 
IST1260I   type TRUNCATED-INSUFFICIENT STORAGE
IST701I    CONFIG configname LABEL = labelname STMT TYPE = statementname
IST314I    END
type indicates the specified resource and can be one of the following:
  • NETWORK NODE SERVER LIST
  • ADJACENT CLUSTER TABLE
  • COSMAP TABLE
  • TRS TOPOLOGY TRACE TABLE
  • APPN ROUTE TRACE TABLE

IST701I

This message identifies where in the resource the truncation occurred.
  • If type is NETWORK NODE SERVER LIST:
    • configname is the name assigned to the VBUILD definition statement.
    • labelname is the name of the network node specified on the NETSRVR definition statement.
    • statementname is the NETSRVR definition statement.
  • If type is ADJACENT CLUSTER TABLE or COSMAP TABLE:
    • configname is the name assigned to the VBUILD definition statement.
    • labelname is the name specified by NETID on the NETWORK definition statement.
    • statementname is the NETWORK definition statement.

The VTAM definition statements and tables are described in the z/OS Communications Server: SNA Resource Definition Reference.

System action

VTAM uses as many of the entries as it is able to process successfully and ignores the rest.

If type is TRS TOPOLOGY TRACE TABLE or APPN ROUTE TRACE TABLE, the table will be truncated at the end of the already allocated buffer of storage and additional entries in the table will wrap back to the beginning of the table. If storage is available the next time the end of the trace table is reached, another attempt will be made to allocate an additional buffer of storage for the table.

If type is NETWORK NODE SERVER LIST, an entry indicating that any known network node can act as the network node server is added at the end of the truncated list.

Processing continues.

Operator response

Issue the DISPLAY BFRUSE command to display information about the common storage area (CSA). Total VTAM private storage information is also displayed in message IST981I. Issue the DISPLAY STORUSE command to display storage usage for storage pools.

If type is ADJACENT CLUSTER TABLE or COSMAP TABLE, enter a DISPLAY ADJCLUST command or a DISPLAY COSMAP command to determine which entries were recorded.

Save the system log and request a dump for problem determination.

System programmer response

Increase storage as required.

If type is NETWORK NODE SERVER LIST, after the storage shortage problem is corrected:
  • Ask the operator to enter the VARY ACT,ID=member_name command where member_name is the name of the definition list member that contains the network node server list.

See the z/OS Communications Server: SNA Operation for more information.

See the z/OS Communications Server: SNA Diagnosis Vol 2, FFST Dumps and the VIT for information about analyzing dumps and about analyzing storage using the VIT analysis tool, if external trace is active.
