IST820I

Explanation
 VTAM® did
not have sufficient storage to receive the response data included
on ACTLU or ACTPU sent by node nodename.  The data
was discarded.

System action
 Node nodename is deactivated.

Operator response
 Enter a DISPLAY BFRUSE or DISPLAY STORUSE
command to check the availability of storage. Wait and     try the
activation of nodename again when storage is available.
 If
the problem persists, save the system log and dump for problem determination.

System programmer response
 Verify that the operator entered
the buffer pool or CSA start options as specified in the start procedures.
 Increase
storage as required. For insufficient storage errors, 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 (ATCSTRxx)
and restart VTAM to use the
start option.  See the z/OS Communications Server: New Function Summary to determine the storage requirements for VTAM.
See the z/OS Communications Server: SNA Resource Definition
Reference for a description of VTAM start options.
See z/OS Communications Server: SNA Operation for information about the DISPLAY BFRUSE
command, the DISPLAY STORUSE command, and the MODIFY VTAMOPTS command.
See the z/OS Communications Server: SNA Network Implementation
Guide for an explanation and description of buffer
pools and for general information on buffer pool specification and
allocation.
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.
