I, Nigel Stokes, certify that:

1.    I have reviewed this annual report on Form 20-F of DataMirror
      Corporation;

2.    Based on my knowledge, this annual report does not contain any untrue
      statement of a material fact or omit to state a material fact necessary
      to make the statements made, in light of the circumstances under which
      such statements were made, not misleading with respect to the period
      covered by this annual report;

3.    Based on my knowledge, the financial statements, and other financial
      information included in this annual report, fairly present in all
      material respects the financial condition, results of operations and
      cash flows of the registrant as of, and for, the periods presented in
      this annual report;

4.    The registrant's other certifying officers and I are responsible for
      establishing and maintaining disclosure controls and procedures (as
      defined in Exchange Act Rules 13a-14 and 15d-14) for the registrant and
      have:

      a.  designed such disclosure controls and procedures to ensure that
          material information relating to the registrant, including its
          consolidated subsidiaries, is made known to us by others within
          those entities, particularly during the period in which this annual
          report is being prepared;
      b.  evaluated the effectiveness of the registrant's disclosure controls
          and procedures as of a date within 90 days prior to the filing date
          of this annual report (the "Evaluation Date"); and
      c.  presented in this annual report our conclusions about the
          effectiveness of the disclosure controls and procedures based on our
          evaluation as of the Evaluation Date;

5.    The registrant's other certifying officers and I have disclosed, based
      on our most recent evaluation, to the registrant's auditors and the
      audit committee of registrant's board of directors (or persons
      performing the equivalent function):

      a.  all significant deficiencies in the design or operation of internal
          controls which could adversely affect the registrant's ability to
          record, process, summarize and report financial data and have
          identified for the registrant's auditors any material weaknesses in
          internal controls; and
      b.  any fraud, whether or not material, that involves management or
          other employees who have a significant role in the registrant's
          internal controls; and

6.    The registrant's other certifying officers and I have indicated in this
      annual report whether or not there were significant changes in internal
      controls or in other factors that could significantly affect internal
      controls subsequent to the date of our most recent evaluation, including
      any corrective actions with regard to significant deficiencies and
      material weaknesses.
