Recovery

Naturally, you can also restore the database “manually”, i.e. without using the 
automatic facilities of NSR-ORA.

Figure 6: The recovery component

The recovery until time (with the command ora_recut) allows the database to be 
recovered for an optional point in time. Thus it is also possible to automatically 
recover logical errors in the database.

Changes made to the structure of the database can also be reversed, since 
ora_recut

 also recovers the saved control file for the relevant point in time. 

   The database must be physically sound (operable) because ora_recut 

needs to query the position of the control files (not for NetApp filers).
