> Possible values for derby.storage.rowLocking Derby engine is not currently documented eventhough the property is at:
> http://db.apache.org/derby/docs/10.1/devguide/cdevconcepts23810.html
> 'derby.storage.rowLocking' basically disable RLL (row-level locking) in the engine.
> The possible values for 'derby.storage.rowLocking' which are 'true', 'false' and the default value are not documented at:
> http://db.apache.org/derby/docs/10.1/tuning/ctunproper22250.html
> Extract from the source code related to 'derby.storage.rowLocking' derby engine property definition:
>    /**
>     * In cloudscape products which support Row Level Locking (rll), use this
>     * property to disable rll.  Application's which use rll will use more
>     * system resources, so if an application knows that it does not need rll
>     * then it can use this system property to force all locking in the system
>     * to lock at the table level.
>     *
>     * This property can be set to the boolean values "*true*" or "*false*".     * Setting the property to true is the same as not setting the property at
>     * all, and will result in rll being enabled.  Setting the property to
>     * false disables rll.
>     *
