Syntax options:

    ASYNC BATCH WRITES ARE ENABLED | ASYNC BATCH WRITES ARE DISABLED

    Specifies whether asynchronous batch-writes are enabled or
    disabled.

    Asynchronous batch-writes allow a process to write batches of
    modified data pages to disk asynchronously (the process does not
    stall while waiting for the batch-write operation to complete).
    Asynchronous batch-writes improve the performance of update
    applications without the loss of data integrity.

    By default, batch-writes are enabled. For more information about
    when to use asynchronous batch-writes, see the Oracle Rdb7 Guide
    to Database Performance and Tuning.

    You can enable asynchronous batch-writes by defining the logical
    name RDM$BIND_ABW_ENABLED.
