> 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.
