public interface Property
List of all properties understood by the system. It also has some other static fields.
This class exists for two reasons
This class should not be shipped with the product.
This class has no methods, all it contains are String's which by are public, static and final since they are declared in an interface.

static final java.lang.String DURABILITY_PROPERTY
Currently the only valid supported case insensitive value is 'test'
Note, if this property is set to any other value other than 'test', this
property setting is ignored
In the future, this property can be used to set different modes - for
example a form of relaxed durability where database can recover to a
consistent state, or to enable some kind of in-memory mode.
When set to 'test', the store system will not force sync calls in the
following cases
- for the log file at each commit
- for the log file before data page is forced to disk
- for page allocation when file is grown
- for data writes during checkpoint
That means
- a commit no longer guarantees that the transaction's modification
will survive a system crash or JVM termination
- the database may not recover successfully upon restart
- a near full disk at runtime may cause unexpected errors
- database can be in an inconsistent state
This setting is provided for performance reasons and should ideally
only be used when the system can withstand the above consequences.
One sample use would be to use this mode (derby.system.durability=test)
when using Derby as a test database, where high performance is required
and the data is not very important
Valid supported values are test
Example
derby.system.durability=test
One can set this as a command line option to the JVM when starting the
application or in the derby.properties file. It is a system level
property.
This property is static; if you change it while Derby is running,
the change does not take effect until you reboot.

static final java.lang.String MODULE_PREFIX
Defines a new module. Modulename is a name used when loading the definition of a module, it provides the linkage to other properties used to define the module, derby.env.jdk.modulename and derby.env.classes.modulename. The value is a Java class name that implements functionality required by the other parts of a Derby system or database. The class can optionally implement these classes to control its use and startup.
static final java.lang.String SUB_SUB_PROTOCOL_PREFIX
A new subsubprotocol can be defined by specifying the class that handles storage for the
subsubprotocol by implementing the
StorageFactory
or
WritableStorageFactory
interface. This
is done using a property named db2j.subsubprotocol.xxx where xxx is the subsubprotocol name.
Subsubprotocol names are case sensitive and must be at least 3 characters in length.
For instance:
derby.subSubProtocol.mem=com.mycompany.MemStore
defines the "mem" subsubprotocol with class com.mycompany.MemStore as its StorageFactory implementation.
A database implemented using this subsubprotocol can be opened with the URL "jdbc:derby:mem:myDatabase".
Subsubprotocols "directory", "classpath", "jar", "http", and "https" are built in and may not be overridden.
