public interface Property

List of all properties understood by the system. It also has some other static fields.

This class exists for two reasons

  1. To act as the internal documentation for the properties.
  2. To remove the need to declare a java static field for the property name in the protocol/implementation class. This reduces the footprint as the string is final and thus can be included simply as a String constant pool entry.

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.

FORCE_DATABASE_LOCK

public static final java.lang.String FORCE_DATABASE_LOCK
derby.database.forceDatabaseLock
Cloudscape attempts to prevent two instances of Cloudscape from booting the same database with the use of a file called db.lck inside the database directory. On some platforms, Cloudscape can successfully prevent a second instance of Cloudscape from booting the database, and thus prevents corruption. If this is the case, you will see an SQLException like the following: ERROR XJ040: Failed to start database 'toursDB', see the next exception for details. ERROR XSDB6: Another instance of Cloudscape may have already booted the database C:\databases\toursDB. The error is also written to the information log. On other platforms, Cloudscape issues a warning message if an instance of Cloudscape attempts to boot a database that may already have a running instance of Cloudscape attached to it. However, it does not prevent the second instance from booting, and thus potentially corrupting, the database. If a warning message has been issued, corruption may already have occurred. NOTE: When you are using Cloudview, error messages appear in the console or operating system window from which Cloudview was started. The warning message looks like this: WARNING: Cloudscape (instance 80000000-00d2-3265-de92-000a0a0a0200) is attempting to boot the database /export/home/sky/wombat even though Cloudscape (instance 80000000-00d2-3265-8abf-000a0a0a0200) may still be active. Only one instance of Cloudscape should boot a database at a time. Severe and non-recoverable corruption can result and may have already occurred. The warning is also written to the information log. This warning is primarily a Technical Support aid to determine the cause of corruption. However, if you see this warning, your best choice is to close the connection and exit the JVM. This minimizes the risk of a corruption. Close all instances of Cloudscape, then restart one instance of Cloudscape and shut down the database properly so that the db.lck file can be removed. The warning message continues to appear until a proper shutdown of the Cloudscape system can delete the db.lck file. If the "derby.database.forceDatabaseLock" property is set to true then this default behavior is altered on systems where cloudscape cannot prevent this dual booting. If the to true, then if the platform does not provide the ability for cloudscape to guarantee no double boot, and if cloudscape finds a db.lck file when it boots, it will throw an exception (TODO - mikem - add what exception), leave the db.lck file in place and not boot the system. At this point the system will not boot until the db.lck file is removed by hand. Note that this situation can arise even when 2 VM's are not accessing the same cloudscape system. Also note that if the db.lck file is removed by hand while a VM is still accessing a derby.database, then there is no way for cloudscape to prevent a second VM from starting up and possibly corrupting the database. In this situation no warning message will be logged to the error log. To disable the default behavior of the db.lck file set property as follows: derby.database.forceDatabaseLock=true

See Also:
Constant Field Values

DEADLOCK_TRACE

public static final java.lang.String DEADLOCK_TRACE
Turn on deadlock trace to help debug deadlocks. Effect 1: This property only takes effect if DEADLOCK_MONITOR is turned ON for deadlock trace.

Constant Field Values

PAGE_SIZE_PARAMETER

public static final java.lang.String PAGE_SIZE_PARAMETER
The page size to create a table or index with. Must be a multiple of 2k, usual choices are: 2k, 4k, 8k, 16k, 32k, 64k. The default if property is not set is 4k.

See Also:
Constant Field Values

ROW_LOCKING

public static final java.lang.String ROW_LOCKING
In cloudscape products which support Row Level Locking (rll), use this property to disable rll. Application's which use rll will use more system resources, so if an application knows that it does not need rll then it can use this system property to force all locking in the system to lock at the table level. This property can be set to the boolean values "true" or "false". Setting the property to true is the same as not setting the property at all, and will result in rll being enabled. Setting the property to false disables rll.

See Also:
Constant Field Values

DURABILITY_PROPERTY

public static final java.lang.String DURABILITY_PROPERTY
derby.system.durability

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.

See Also:
Constant Field Values

DURABILITY_TESTMODE_NO_SYNC

public static final java.lang.String DURABILITY_TESTMODE_NO_SYNC
This is a value supported for derby.system.durability When derby.system.durability=test, the storage system does not force syncs and the system may not recover. It is also possible that the database might be in an inconsistent state

See Also:
DURABILITY_PROPERTY 55 , Constant Field Values

FILESYNC_TRANSACTION_LOG

public static final java.lang.String FILESYNC_TRANSACTION_LOG
derby.storage.fileSyncTransactionLog

When set, the store system will use sync() call on the log at commit instead of doing a write sync on all writes to the log; even if the write sync mode (rws) is supported in the JVM.
