The accounting journal QSYS/QACGJRN is processed as any other journal. Files can also be recorded in this journal although for simplicity it is recommended that you keep it solely for accounting information.
You can use the Send Journal Entry (SNDJRNE) command to send other entries to this journal. While there are additional operational considerations involved in using several journals, there are advantages to NOT allowing any file entries in the QACGJRN journal. It is typically easier to control the QACGJRN journal separately so that all job accounting entries for a particular accounting period are in a minimal number of journal receivers and that a new journal receiver is started at the beginning of an accounting period. System entries also appear in the journal QACGJRN. These are the entries with a journal code of J, which relate to IPL and general operations performed on journal receivers (for example, a save of the receiver).
Job accounting entries are placed in the journal receiver starting with the next job that enters the system after the Change System Value (CHGSYSVAL) command takes effect. The accounting level of a job is determined when it enters the system. If the Journal accounting information (QACGLVL) system value is changed after the job is started, it has no effect on the type of accounting being performed for that job. The direct print (DP) and spooled print (SP™) entries occur if the job that created the file is operating under accounting and the system value is set for *PRINT. If spooled files are printed after the accounting level has been set to *PRINT or if the job that created the file was started before the accounting level was changed, no journaling is done for those spooled files.
