Confirm
    Noconfirm

    Specify the Confirm qualifier with the Update qualifier to
    gain more control over the update function. When you specify
    the Confirm qualifier, you are asked whether the update should
    be performed for each selected table or index whose stored
    cardinality value is different from its actual cardinality value.
    You can respond with YES, NO, QUIT, or an alternative value for
    the stored cardinality.

    Specifying YES means that you want to update the stored
    cardinality with the actual cardinality value. Specifying NO
    means that you do not want to update the stored cardinality
    value. Specifying QUIT aborts the RMU Analyze Cardinality
    command, rolls back any changes you made to stored cardinalities,
    and returns you to the operating system prompt. Specifying an
    alternative value updates the stored cardinality value with the
    alternative value.

    When you specify the Noconfirm qualifier, you are not given the
    option of updating stored cardinality values with an alternative
    value of your own choosing. Instead, the stored cardinality
    values that differ from the actual cardinality values are
    automatically updated with the actual cardinality values.

    The default is the Noconfirm qualifier.

    The Confirm and Noconfirm qualifiers are meaningless and are
    ignored if they are specified without the Update qualifier.
