Examples of LockStats

com.sleepycat.je.LockStats
Lock statistics for a database environment.
Note that some of the lock statistics may be expensive to obtain because the lock table is unavailable to other operations while the statistics are gathered. These expensive statistics are only provided if {@link com.sleepycat.je.Environment#getLockStats Environment.getLockStats} iscalled with a StatsConfig parameter that has been configured for "slow" stats. @deprecated as of 4.0.10, replaced by {@link Environment#getStats(StatsConfig)}.
