When you open the .cd file, the following contents appear:

  • First row — Contains information of a single CDC table policy. This row has an identifier or tag called “Table” as a prefix to identify that the policy is a CDC table policy. The value at the end of the row indicates the number of field policies associated with the CDC table policy.
    Each column in the first row appears in the following oder:
    Column Description
    Table The identifier or tag to identify that the policy is a CDC table policy.
    Policy Name The name of the table policy.
    Description The description of the policy.
    State The internal state of the policy.

    The values are 0 and 1 for Active and Inactive respectively.
    Instance The policy on the source table.

    The values are 0, 1, and 2 for Current policy, Previous policy, and Pending policy respectively.
    Source Table The name of the source table.
    Source Table Owner The name of the owner of the source table.

    The source table can be a PUB or non-PUB table.
    Data Area The storage area where the change table.
    Index Area The storage area where the change table indices are created.
    Identifying Fields Indicates if the Identifying fields are available for the policy.

    The values are Yes and No.
    Level The level of data that is captured on the source table.
    The levels are:
    • Minimal(0)
    • MinimalWithBitMap(1)
    • Medium(2)
    • Maximum(3)
    Change Table The name of the change table.
    Change Table Owner The name of the non-PUB or PUB owner of the change table.
    Encrypt Policy The encryption policy used for the change table.

    The values are Yes and No.
    Misc Fields This is an extent [16] field and the values are non-editable.

    All values of _Misc fields for _Cdc-Table-Policy are dumped.
    Field Policy Count The number of field policies available for a table policy.

    A value of zero (0) indicates that there are no field policies available for that table policy.
    For a CDC table policy in a .cd file, the following fields are ignored:
    • _Policy-Id
    • _Last-Modified
    • _ObjectId
    • _First-User-Field
    Though the _Policy-Instance field is dumped, it can be overridden when loading the .cd file.
    Note: You cannot set the _Policy-Instance field value directly. To set the required _Policy-Instance field value, you must change the _Policy-State field value during the loading process.
    In the _Cdc-Table-Policy table, the name of the source table is identified from the _Source-File-Recid, and the data and index areas are identified from the _Area-Ianum and _Index-Area-Ianum fields.
  • Subsequent rows — Contain information of the field policies associated with the CDC table policy. These rows have an identifier or tag called “Field” as a prefix to identify that the policies are field policies, followed by the name of the CDC policy name that they belong to.
    Each column in these rows appears in the following order:
    Column Description
    Field The identifier or tag to identify that the policy is a CDC field policy.
    Policy Name The name of the corresponding CDC table policy.
    Field Name The name of the field.
    Identifying Fields Indicates if the Identifying fields are available for the policy.

    The values range from 1 to 15 and indicate ordinal position in the index.
    Misc Fields This is an extent [16] field and the values are non-editable.

    All values of _Misc fields for _Cdc-Field-Policy are dumped.
    For a CDC field policy in a .cd file, the following fields are ignored:
    • _Policy-Id
    • _Field-Position
    • _Field-Recid
    In the _Cdc-Field-Policy table, the name of the field is identified from the _Field-Recid field.
  • Trailer — Contains information of the .cd file such as its name, the number of CDC table policies available in the file, the name of the database from which the policies are dumped, time and date when the dumping process completed, and format of the code page.
    Each row in the trailer appears in the following order:
    Row Description
    filename The name of the .cd dump file.
    records The number of CDC table policies available in the dump file.
    ldbname The name of the database from which the policies are dumped.
    timestamp The time and date when the policies are dumped.
    numformat The numeric format
    dateformat The format of the date when the policies are dumped.
    cpstream The format of the code page in which you want the CDC policies to be dumped.
