Specifies the number of buffers allocated to the automatic
    recovery process that Oracle Rdb initiates after a system or
    process failure. This recovery process uses the recovery-unit
    journal (.ruj) file.

    Specify an unsigned integer greater than or equal to 2 and less
    than or equal to 32,767. The default value for the NUMBER OF
    RECOVERY BUFFERS parameter is 20 buffers. If you have a large,
    multifile database and you are working on a system with a large
    amount of memory, specify a large number of buffers. This result
    is faster recovery time. However, make sure your buffer pool does
    not exceed the amount of memory you can allocate for the pool.
    if the number of buffers is too large for the amount of memory on
    your system, the system may be forced to perform virtual paging
    of the buffer pool. This can slow performance time because the
    operating system must perform the virtual paging of the buffer
    pool in addition to reading database pages. You may want to
    experiment to determine the optimal number of buffers for your
    database.

    Use the NUMBER OF RECOVERY BUFFERS option to increase the number
    of buffers allocated to the recovery process.

    SQL> CREATE DATABASE FILENAME personnel
    cont>  NUMBER OF RECOVERY BUFFERS 150;

    This option is used only if the NUMBER OF RECOVERY BUFFERS value
    is larger than the NUMBER OF BUFFERS value. For more information,
    see the Oracle Rdb Guide to Database Maintenance.
