3. Start up the database instance in nomount state. 4.Mount the database.

  1. Restore the data files.

  2. Open the database with the resetlogs option. 7.Recover the data files.

8.Set D3ID for the database.

Identify the required steps in the correct order.

A. 1, 8, 3, 2, 4, 5, 7, 6

B. 8, 1, 3, 2, 4, 5, 7, 6

  2. Use the RMAN convert command to convert data files to the target platform#39;s endian format, if required.

  3. Perform a full transportable export on the source database with the parameters

    VERSI0N=I2, TRANSPORTABLE=ALWAYS, and FULL=Y.

  4. Transport the data files forall the user-defined tablespaces.

  5. Transport the export dump file to the target database.

  6. Perform an import on the target database by using the full, network_link, and transportable_datafiles parameters.

  7. Perform an import on the target database by using the full and transportable_datafiles parameters.

Identify the required steps in the correct order.

A. 1, 3, 5, 4, 2, and 6
