BYPASS

Use the BYPASS function to set a certain record type or group of records in a record type so they are not captured. For example:
  • If you do not want to capture hexadecimal record type 0009, enter:
    • ZDBRO BYPASS RECtype-0009
    or
    • ZDBSO BYPASS RECtype-0009

    The BYPASS option sets the control bits that are ignored or preserved by the BYPASS parameter of the INIT command. When BYPASS=YES on the INIT function, the capture bits that are set with the BYPASS function are ignored.

    A practical instance of the BYPASS function involves the PROT table. The output tape device used by DBR is identified in the PROT table. This table is captured by the DBR output phase and restored by the DBR input phase. When the restored system comes online, the previous PROT table takes effect and may not agree with the tape status of the current system unless the same tape device was specified for both phases of DBR. If you cannot avoid using different tape devices, you can bypass the capture of PROT during the output phase, or correct the contents of PROT after the system is restored if the BYPASS function was not used.

  • If you want to capture hexadecimal record type 0009, but do not want to capture ordinals 020-035 in that record type, enter:
    • ZDBRO BYPASS RECtype-0009 RANGE-020.035
    or
    • ZDBSO BYPASS RECtype-0009 RANGE-020.035
  • If you want to capture only pool records that are in use, enter:
    • ZDBRO BYPASS DIR
    or
    • ZDBSO BYPASS DIR
