Description

Summary

When importing an XML Backup from Cloud to Server on Oracle 12c, the process fails.

Environment

Oracle 12c with ojdbc6 and ojdbc7 driver
Oracle 12c 12.1.0.2.0 with ojdbc8 driver

Steps to Reproduce

Export an XML Backup from Cloud
Modify the pdata file in the XML Backup (details here CONF-28272)
Make sure to create the all_objects view as recommended in our Database Setup guide for Oracle
Install a fresh instance of Confluence 5.10.x or 6.0.x using Oracle JDBC Driver (either ojdbc6 or ojdbc7)
Go through the initial setup
Import Content from a Backup

Expected Results

The import should run without any problems

Actual Results

The import runs fine until it reaches the part of importing the AO tables data and throws the following error in the logs. The UI rolls back to 90% until it exits with an error. (Eventhough we applied the fix on the pdata)

Workaround

The current workaround is not perfect but it does the job:

Bring up Confluence from scratch, and make sure it's up and running as a blank instance
Go to the "Backup & Restore" page ready to import your backup file
Directly in the database, drop all AO sequences (but do not drop any that are not prefixed by AO_)
Start the import

Sometimes the first time, it doesn't work but if you run it again right after it, it works!
