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.

There are various situations when you can use this process such as when re-installing Dbvisit StandbyMP from the scratch or even manually importing older version DDC file after failed or incomplete upgrade. Oracle DDC file is standalone entity and can be used to quickly add existing standby database to you your dbvcontrol dashboard.

Info

There is no need to recreate standby database when importing DDC file (if the standby database is healthy).

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.

Info

you need to be sure that the version of the DDC file you’re restoring doesn’t have significant differences - for example primary and standby server roles are the same in the DDC file as you would expect. You can easily swap the Primary and Standby server roles by running dbvctl command:

Code Block
/usr/dbvisit/standbymp/oracle/dbvctl -d SLASH -o update_ddc_file
=============================================================
Dbvisit Standby Database Technology (12.1.0RC) (pid 2823091)
dbvctl started on czlin0231: Mon Feb 24 14:20:01 2025
=============================================================
>>> Dbvisit Database configuration (DDC) file
    /usr/dbvisit/standbymp/oracle/conf/dbv_SLASH.env has been updated and variables have
    been reversed between primary and standby server
    SOURCE=czlin0232 DESTINATION=czlin0231

Note the last line tells you the actual server roles (SOURCE = primary server, DESTINATION = standby server) - this must be in line with what you expect. If not, run the command again

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