Function
Causes a detailed list of locks at the time of a deadlock or a timeout
to be written to the error log (typically the file derby.log). For a
deadlock, describes the
cycle of locks which caused the deadlock. For a timeout,
prints the entire lock
list at the time of the timeout. This property is meaningful only if the
derby.locks.monitor
property is set to true.
This level of debugging is intrusive: it can alter
the timing of the application, reduce performance severely, and produce a
large error log file. It should be used with care.
