Parameter Description for SMFDEF

BUFNUM=nnnn|5

Specifies the number (0-1000) of system management facilities (SMF) buffers JES2 obtains. If the value specified is less than 2, JES2 will neither produce SMF records nor take the SMF exit, IEFUJP.

When determining the value of nnnn, be aware that the SMF buffers used for the 3800 printer output remain in use until all associated output is stacked. Additionally, multiple SMF buffers can be active concurrently for the 3800. Therefore, the minimum number of SMF buffers, for an installation that uses 3800 printers should be:

5 + n + (30 / p) y + o + pu

where:

n=: number of non-3800 printers
p=: average number of pages per data set for each 3800 printer
y=: number of 3800 printers
o=: 3 x (number of offload devices)
pu=: 2 x (number of purge processors)

Use your present SMF records to determine the average number of pages per data set currently processed by each 3800. Dividing 30 by this value (the average number of pages per data set currently processed by each 3800 printer) provides the average number (generally not more than 2) of job output elements (JOEs) that represent active work on all 3800 printers. (Active work is represented by those JOEs that were sent to the 3800 printer but have not been completely stacked.)

The value specified for BUFNUM is rounded up so that the storage used for SMF buffers is a whole number of pages.

Note:

Use this parameter to increase the limit for the JNUM resource that is reported on the HASP050 message. End of change

Modification: Single-member warm start.

BUFWARN=nnn|80

Specifies the percentage (0-100) of SMF buffers in use at which the operator will be alerted by message $HASP050 JES2 RESOURCE SHORTAGE. If you specify 0, no alert is given.

Modification: $T SMFDEF operator command.
