Not using the FULL option
If the FULL option is not specified, the space utilization report is based on information on the Space Management Pages. The information reported may vary widely from the actual space utilization. For example, if all pages in a particular segment were 50% full, the SMP pages will indicate that each page is 100% available. When using the default on the PRINT SPACE utility, the report will indicate that the database is being used at a 0% level. When running the PRINT SPACE utility with the FULL option, the report will indicate that your database is 50% utilized.
Running Under Central Version
Only PRINT SPACE FOR AREA and PRINT SPACE FOR SEGMENT are supported under central version.
Logically-deleted records and reports
PRINT SPACE BY FILE sequentially reads the files, letting you include only the files in the JCL stream that you want to process.
When you use this option, PRINT SPACE will not report relocated logically deleted records as logically deleted. These records will be reported as normal records. Therefore, record space utilization reports for an area can produce different results when compared to the file report for the same page range.
