The DBA needs to know when recreating the control file, but it may not be able to reproduce the system throughout his career.

First of all, it is emphasized that backup is the safest, quickest, and effective recovery method. If a DBA does not plan an effective backup, one day, the Hong Kong server will be awakened by a nightmare.

After waking up, It is helpless, complicated and manual recovery. In addition, to what extent can we restore the space in Hong Kong, we have to look at the sky and life. We can't look at ourselves. Because there is no backup, you have already handed over the initiative to others. Record the reconstruction of controlfile

Create controlfile trace on other normal Databases

  • The trace file path is under user_dump_dest.

    For a complete trace, see the attachment.

    You can modify the path and other specific parameter values of the trace file and extract the creation script

    Register archivelog

    In fact, rebuilding the control file is equivalent to manually re-creating the database, adding existing database resources to the controlfile one by one, and finally registering the current archivelog file.

    At the same time, the reconstruction of controlfile can be divided into NORESETLOGS and RESETLOGS. Select the corresponding script as needed.

    At the end of the day, it was a nightmare to back up the data effectively. The US space was always ready !!
