IST182I

Explanation
 VTAM® was
unable to obtain VTAM private
storage for checkpointing of the specified major node.
 datasetname is
the checkpoint data set DDNAME.
 nodename is
the major node name.

System action
 VTAM terminates
checkpointing for this major node. If nodename is
a major node named in a VARY ACT command (with the WARM operand),
processing of the command terminates. 

Operator response
 Issue the DISPLAY STORUSE command to display
storage usage for storage pools. Message IST981I displays total VTAM private storage information.
If this message does not appear in the display, you might need to
reissue the DISPLAY STORUSE command, specifying a higher value for
the NUM operand. See z/OS Communications Server: SNA Operation for information about the DISPLAY STORUSE
command.
 Save the system log and request a dump for problem
determination.

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