IST074I

Explanation
 A command for nodename failed
because VTAM® could not obtain
a work area to process the request.

System action
 VTAM rejects
the command. 

Operator response
 Messages IST561I, IST562I, IST563I, IST564I,
IST565I or IST566I might be issued prior to this message to indicate
the type of storage affected. 
 Issue the DISPLAY BFRUSE command
to display storage used by VTAM buffer
pools and information about the common service 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.
 Save the system
log and request a dump for problem determination.
 If nodename is
an independent logical unit that is being converted to a definition
for a resource in another domain, then the NCP major node for nodename must
be deactivated. Activate the NCP major node when the storage shortage
no longer exists. 

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.

1, Techniques and Procedures for information about analyzing dumps and
about analyzing storage using the VIT analysis tool, if external trace
is active.
