# Derby properties

The Derby properties are used for configuring the system and database, as well as for diagnostics such as logging statements, and monitoring and tracing locks.

This section includes all of the core Derby properties.
Note: When setting properties that have boolean values, be sure to trim extra spaces around the word true. Extra spaces around the word true cause the property to be set to false.
Derby properties summarizes the general Derby properties. In this table, S stands for system-wide, D stands for database-wide, and C indicates the value persists with newly created conglomerates. X means yes.
