Is it possible to take an export backup of a standby database? And how?
What mode is the standby database running in? If the standby database is in managed recovery mode, then you cannot connect to the database and read the table's contents, therefore you will not be able to take an export of the standby database. However, you can switch the standby database to READ ONLY mode and create your export dump. During this time, your standby database will not be applying any redo and it will become out of sync with your production database. You can have the standby catch up with production once you place it back in managed recovery mode. But during this time, you will be unprotected.
