DROPMAP subcommand — delete storage map records

Use the DROPMAP subcommand to delete records from the storage map in a source description for a dump. The source description is in the dump directory allocated with ddname IPCSDDIR and is your current dump directory. The current dump directory is your user dump directory or, for users with write access authority, might be the sysplex dump directory.

    -------- SETDEF-Defined Parameter --------------------------
    Note: You can override the following SETDEF parameter.
    See SETDEF subcommand — set defaults.

  • Parameters
    RANGE(address:address)
    Specifies that the range of addresses in the dump for which map records exist are to be deleted. The range can be specified as an address and a length or as a range of addresses.

    If you omit the range parameter, the subcommand deletes all map record s for the dump.

    If a map record describes an address within the range, the subcommand deletes the map record.

    data-descr
    Specifies the data description parameter, which consists of five parts:
    • An address (required with the RANGE parameter and when data-descr is explicitly specified on the subcommand)
    • Address processing parameters (optional)
    • An attribute parameter (optional)
    • Array parameters (optional)
    • A remark parameter (optional)
    Data description parameter explains the use and syntax of the data description parameter.

    If you specify address processing parameters (which are optional) but omit the address (which is required), the subcommand deletes all map records for the address space.

    SUMMARY or NOSUMMARY
    SUMMARY indicates that a processing summary (a final total line) is to be produced.

    NOSUMMARY specifies that a processing summary is to be suppressed. The NOSUMMARY parameter is useful to turn off summary messages when the subcommand is invoked within a CLIST or a REXX exec.
