Description

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.
  *
