    Me too....

    Disabling oplocks will have a performance impact on any database application, whether an ISAM database or client/server database is used (but will not affect the data integrity of any database).
    This now has me baffled. The part in parens (to my little brain) contradicts what the whole white paper is about.

    Shouldn't it be:

    but will not affect the data integrity of any client/server database

    ???

    Maybe I need to rephrase that whole section of the paper.

    Current:

    Disabling oplocks will have a performance impact on any database application, whether an ISAM database or client/server database is used (but will not affect the data integrity of any database).

    This paper will tell you how to disable oplocks, but due to the reasons stated above, Data Access Worldwide recommends using a client-server database for multi-user DataFlex applications on Windows networks.

    Oplocks do not apply to client-server databases. DAW makes no specific recommendation on oplocks if you use a client server database and no embedded database tables.

    Revised:

    Disabling oplocks may have a performance impact on Windows networks.
