Don't let improperly managed deleted records slow down system performance.
Written by Sandra Cabral
When records are deleted or marked for deletion, they may remain as part of the physical file. It is a good practice to run the RGZPFM command to remove deleted records and free up DASD. Removing deleted records can improve performance of programs that read a file sequentially. It can also help reduce the paging of data in from DASD to memory. The recommendation is to run RGZPFM if the number of deleted records exceeds 20 percent of the total number of records in the file.
