Question : oracle error: ORA-01665: control file is not a standby control file

Hello,
  I am new to oracle and I created a standby database in a different location. the log were transferred ok. I tried to break standby by creating  a 10g Flashback Database

Now, I get an error  when I tried to undo and make the db a standby again I get the error "ORA-01665: control file is not a standby control file".

How do I solve this issue?. Do I have to redo the data guard procedure ?

Thanks

I think no standby redo logs file are there on standby database side.

To create standby redo log see this:
