With Functions
Create GG_FUN table on proddb

7. Create GG_FUN_TEST on devdb

8. Connect to database via Golden Gate and add table level
supplemental logging

9. CREATE SOURCE
DEFINITIONS FILE
First, we need to create a parameter file for DEFGEN utility. You
can create it via GG prompt or manually via vi editor

11. Exit the GG prompt and initiate defgen utility to generate
definitions file
Copy the definitions file on target server under
$GG_HOME/dirdef location

12. Create extract on source
