Parameters

BELOWBUF=

The specifications for buffers that reside below 16 megabytes of virtual storage.

FREE: The current number of free buffers.
LIMIT: The maximum number (10-2000) of buffers that is allowed.
WARN: The percentage (0-100) of local buffers used at which the $HASP050 message alerts the operator of a shortage of local buffers. JES2 deletes this message from the console when the resource shortage is relieved (either by a decrease in resource use or an increase in the threshold).

EXTBUF=

The specifications for buffers that reside above 16 megabytes of virtual storage.

FREE: The current number of free buffers.
LIMIT: The maximum number (10-9999) of buffers that is allowed.
WARN: The percentage (0-100) of local buffers used at which the $HASP050 message alerts the operator of a shortage of local buffers. JES2 deletes this message from the console when the resource shortage is relieved (either by a decrease in resource use or an increase in the threshold).

Authority Required

This command requires display authority. The description of the $T RDRnn command explains how to ensure that the authority of the appropriate MVS™ system command group is assigned.

This command requires read security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide, SA32-0991.

Scope

Single member. The values supplied for this command will be in effect for this member only. There is no need to have this command issued to all members of the MAS.

Messages

The $HASPxxx messages display the current values for all the parameters on the BUFDEF statement.

Example

 1   $d bufdef

  $HASP840 BUFDEF  BELOWBUF=(LIMIT=1000,WARN=80,FREE=823),
  $HASP840         EXTBUF=(LIMIT=1000,WARN=80,FREE=243)

JES2 displays the buffer definitions and current free counts.
