Specifies that Replication Option create an extraction rollup
    database at the target site with records selected from one or
    more source databases. Because each extraction rollup database is
    independent of the source database, users at the target directory
    can access extraction rollup databases with either read-only or
    read/write transactions. Each time an extraction rollup transfer
    executes, Replication Option creates a new version of the
    target database and transfers a complete copy of the selected
    records to the target node.

    Indexes, constraints, and access rights are not transferred when
    the target database is created. Once the target database has been
    created, you can define indexes and constraints for it and modify
    the access rights. Refer to the Replication Option Handbook for
    more information about extraction databases.
