Abstract
In response to identifying an update operation for a system table of a DBMS, a row that corresponds to the update operation is identified using a partial image of the update operation. A before image that corresponds to the row is gathered and a new before image of the row that reflects the update operation is generated by overlaying the before image with the partial image. In response to identifying a delete operation that relates to the system table, a row of the system table that corresponds to the delete operation is identified using an identifier of the delete operation. A before image that corresponds to this row is gathered. A new before image of the row of the system table that reflects the delete operation is generated by applying the delete operation to this before image.
