Bug: Replica system versions are not cleaned up after receiving an acknowledgement

Description

When synchronizing a replica, system versions are created and removed. When an acknowledgement message is received, system versions that are no longer needed are removed. With this bug, however, there are some cases where they are not removed. Leaving these unneeded system versions can have an effect on the compress process.

Cause

This is a known issue.

Workaround

Exporting a data changes message triggers the logic to remove the unneeded versions. Run this any time after receiving an acknowledgement message; for example, when sending changes using connected synchronization or when receiving an acknowledgement message explicitly.

Since the message is being exported for the purposes of deleting the system versions, it is not necessary to send the message. Any changes in this delta file will be sent again with the next synchronization. It is also possible to set options to export the message without any changes. The following describes how:

  1. Run the Export Data Change Message geoprocessing tool.
  2. Enter the replica geodatabase, data changes file, and replica.
  3. Uncheck the Switch to Receiver once the message has been exported, include unacknowledged data changes, and include new data changes since last export check boxes.
  4. Click OK to create the delta file. Once the process completes, unneeded system versions should be removed.

    Note:
    There is an ArcGIS 9.3 Service Pack 1 patch that addresses this issue.
