Properties overview

Derby lets you configure behavior or attributes of a system, a specific database, or a specific conglomerate (a table or index) through the use of properties.

• Scope of properties
  You use properties to configure a Derby system, database, or conglomerate.
• Persistence of properties
  A database-wide property always has persistence. That is, its value is stored in the database.
• Precedence of properties
  The search order for properties is as follows.
• Dynamic versus static properties
  Most properties are dynamic; that means you can set them while Derby is running, and their values change without requiring a reboot of Derby. In some cases, this change takes place immediately; in some cases, it takes place at the next connection.
