    CHGPF is changing the physical file command in AS400, i.e., CHGPF. This command changes the PF attributes and structure without losing the actual data stored in PF.
    CHGPF FILE(TESTLIB/PF1) SRCFILE(PF1/QDDSSRC) SRCMBR(PF1)
    We can change the following attributes of a PF using the CHGPF command:

    • Maximum members
    • Access path maintenance
    • Member size
      • The initial number of records
      • increment number of records
      • maximum increments
    • Share open data path
    • Reuse deleted records
