The amount of lock list memory currently in use for a database or database partition. This value is shown in bytes. If the value is high, you might want to increase the size of the locklist configuration parameter.
Note: In most cases, the aggregate row for a multi-partition database shows the sum of numeric values for its partitions. However, the aggregate value shown for Lock List Usage may not always be the sum of the values shown for its partitions. This is because data for the partitions is not acquired simultaneously.
