Job Accounting
Job accounting is a function available on every i5/OS™ system that
can be used to track usage of system resources. The
journal accounting information system value (QACGLVL) determines what type
of system usage information is journaled to the system accounting journal (QACGJRN).
The type of information that can be collected includes processing unit time used
(CPU), transaction counts, time job was active, number of database operations,
communications operations, and number of printed pages. A full list of fields found
in the accounting journal entries can be found in the Table:
JB, DP, and SP journal entries section of the PDF. This information can
be used to track resource usage for a particular user or group of users. Queries
or application programs can be written to use this data for several purposes such
as charging users for use of system resources, analyzing performance, or statistical
analysis. This experience report covers how to set up job accounting, special
considerations for prestart or server jobs, and how to look at the data after it has
been collected.
