Physical file member operations

These topics describe the member operations that are unique to physical file members. If the physical file members being operated on are associated with referential constraints, the operations might be affected.

• Initialize data in a physical file member
  To use relative record processing in a program, the database file must contain a number of record positions equal to the highest relative record number used in the program. Programs using relative-record-number processing sometimes require that these records be initialized.
• Clear data from physical file members
  The Clear Physical File Member (CLRPFM) command removes the data from a physical file member. After the clear operation is complete, the member description remains, but the data is gone.
• Reorganize a physical file
  These topics describe how to reorganize physical files on the i5/OS™ operating system, how to suspend or cancel reorganize operations and what type of reorganize operations you can choose. Considerations for reorganizing physical files are also included.
• Display records in a physical file member
  The Display Physical File Member (DSPPFM) command displays records in a physical file member.
