'AVG # RECDS/JOB: 2' means that, on average, two records on the AJF file are required to hold the information for one job. Since the AJF file can hold a maximum of 100,000 records (DEFINED RECDS), it can hold approximately a maximum of 50,000 jobs. 'USED RECDS:' is 84,051, which means that there are approximately 42,025 jobs on the AJF file. In percentage terms, approximately 84% of the AJF file is used to hold jobs. Another six percent (6,138/100,000) of the AJF is used to hold index records. Therefore, a total of approximately 90% of the AJF is used for both jobs and indexes.
FREE SPACE-NEW JBS is calculated by dividing 9,811 (FREE RECDS) by 2.00. The result is 4,905. This means that, in theory, 4,905 jobs can be added to the AJF file. Note that when jobs are added to the AJF, index records are also created. Since approximately six percent (6,138/100,000) of the file is used to hold index records, this means that six percent must be subtracted from the 4,905 jobs that can be added to the AJF. Therefore, approximately 4,611 jobs can be added to the AJF.
If the Active Jobs File Space Reuse Facility is active (AJF SPACE REUSE: ACTIVE),
'# RECDS REUSABLE' specifies how many records on the AJF can be reused for new jobs. For more information about the Space Reuse Facility, see the INCONTROL Administrator Guide.
