ORA-38799: Cannot drop guaranteed restore point internally created for snapshot standby

What triggered the Error:

An attempt is made to drop the guaranteed restore point Oracle created internally for a snapshot standby.

What should we do to fix it:

Use the "alter database convert to physical standby" command to convert the snapshot standby to a normal physical standby. This will automatically flashback the database and drop this guaranteed restore point.
