In this section, we will show you how to import or re-import existing Oracle DDC file into dbvcontrol dashboard. DDC file contains complete configuration for a pair of Primary and Standby Oracle database synchronization.

...

Note

DDC file contains all settings needed for Oracle Synchronization. When doing import, you must ensure that all settings stored inside the DDC file are correct (for example primary and standby server roles).

Do not perform import if you’re not sure that all DDC file variables are correct. Instead, create DDC file from scratch instead.

If you’re not sure, skip to “3. Importing pre-version 12 DDC file or importing version 12 DDC file with detailed prechecks” and do full prechecks

Once you verify the primary and standby server roles are correct, you’re ready for GUI import. Start with creating new Oracle configuration:
