$T ESTBYTE

Function

To specify the default amount of spool space needed for a job's output and the action that JES2 takes if the output exceeds this amount.

Syntax


>>-$T--ESTBYTE--+------------------+--+------------------+------>
                '-,--INT--=--nnnnn-'  '-,--NUM--=--nnnnn-'   

>--+------------------+----------------------------------------><
   '-,--OPT--=--+-0-+-'   
                +-1-+     
                '-2-'

Parameters

INT=nnnnn

The interval (1-99999), in thousands of bytes of spool space, at which JES2 repeats the $HASP375 message to the operator.

NUM=nnnnn

The number (1-99999) of bytes of spool space, in thousands, used by a job's output, after which the $HASP375 message informs the operator that the job's estimated output has been exceeded.

OPT={0|1|2}

Specifies the action JES2 takes when a job exceeds the estimated spool utilization value as specified by the NUM= parameter. The options and subsequent action are:

0: Job is allowed to continue execution.
1: Job is cancelled without a dump.
2: Job is cancelled with a dump (if a dump statement was coded for this job step).

Authority Required

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

Processing Considerations

This command affects only those jobs that have not yet been selected for execution.

Scope

Single member. This command will be in effect for this member only.

Depending on your installation's setup, however, you might want this command to be applied to all members of the MAS (to ensure a consistent environment across the MAS). If so, you can use the MVS ROUTE *ALL command to issue this command to all active members (if the JES2 command character is the same on all members). See z/OS MVS System Commands, SA38-0666 for more information on using the ROUTE *ALL command.

Messages

The $HASP845 message displays the current values of all the parameters on the ESTBYTE initialization statement.

Example

 1   $t estbyte,num=4500,int=300

  $HASP845 ESTBYTE NUM=4500,INT=300,OPT=0

If a job's output exceeds 4,500,000 bytes of spool space, JES2 issues the $HASP375 message to inform the operator that the job's output has been exceeded. JES2 reissues this message each time the job exceeds another 300,000 bytes until the job finishes execution.
