The "Excluded Tables" step allows you to exclude Oracle tables by name.
The following fragment is the xml generated when specific tables have been excluded by name:
<TablePairs>
<!--**** excluded pairs ****-->
<Pair Action="Exclude">
<LeftObject Name="EMPLOYEES" />
<RightObject Name="EMPLOYEES" />
</Pair>
<Pair Action="Exclude">
<LeftObject Name="JOBS" />
<RightObject Name="JOBS" />
</Pair>
<Pair Action="Exclude">
<LeftObject Name="REGIONS" />
<RightObject Name="REGIONS" />
</Pair>
