2. Copyright © 2009, Oracle. All rights reserved. 10 - 2 Objectives After completing this lesson, you should be able to do the following: Initialize a mapping debugging session Prepare the testing environment and test data Set breakpoints and watch points Run a test mapping Evaluate the flow of data to detect mapping errors

4. Copyright © 2009, Oracle. All rights reserved. 10 - 4 Mapping Debugger: Overview 1.Initialize a mapping debugging session. 2.Connect to test source and target schemas. 3.Define test data. 4.Create debugging target tables to protect actual targets. 5.Set breakpoints and watch points. 6.Run a test mapping. 7.View data flowing through the mapping to correct errors.

8. Copyright © 2009, Oracle. All rights reserved. 10 - 8 Test Data Tab Shows Tables Not Found Test data not found for source and target table operators Before you can run the mapping in the debug mode, each listed source or target operator must be bound and have a check mark. Use the Edit button to add or change the binding of an operator.

10. Copyright © 2009, Oracle. All rights reserved. 10 - 10 Operator Debug Binding Dialog Box Search for PRODUCTS database table to bind with mapping table operator. You know PRODUCTS is in XSALES schema; SELECT XSALES_LOCATION Select PRODUCTS and click OK

11. Copyright © 2009, Oracle. All rights reserved. 10 - 11 Direct Access to Database Entity The debug binding name is the name of the entity, plus any needed qualifiers for database link or schema.

12. Copyright © 2009, Oracle. All rights reserved. 10 - 12 Define the Other Source Table PRODUCTS is “found”; now find the CATEGORIES table.

13. Copyright © 2009, Oracle. All rights reserved. 10 - 13 Replace Target with a Debugging Table Now that the two source tables are found, edit the target to replace it with a temporary debugging table.

18. Copyright © 2009, Oracle. All rights reserved. 10 - 18 Watch Panel For Non-Data-Based Operators A separate Watch panel is invoked to watch data for non-data- based operators such as Constant, Map Input, Map Output, Premap, Postmap, and Sequence.

19. Copyright © 2009, Oracle. All rights reserved. 10 - 19 Quiz When you are testing a mapping using the Mapping Debugger, you should change the actual target table to a test target table in the mapping. a.True b.False

20. Copyright © 2009, Oracle. All rights reserved. 10 - 20 Quiz After you have set the data sources and targets, which of the following tasks must you perform to restart debugging? a.Resume b.Reinitialize c.Break d.Watch
