List of all properties understood by the system. It also has some other static fields.
This class exists for two reasons
- To act as the internal documentation for the properties.
- 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.

gemfirexd.distributedsystem.forceDatabaseLock
Derby attempts to prevent two instances of Derby from booting
the same database with the use of a file called db.lck inside the
database directory.
On some platforms, Derby can successfully prevent a second
instance of Derby 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 Derby may have already booted the
database C:\databases\toursDB.
The error is also written to the information log.
On other platforms, Derby issues a warning message if an instance
of Derby attempts to boot a database that may already have a
running instance of Derby 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.
The warning message looks like this:
WARNING: Derby (instance 80000000-00d2-3265-de92-000a0a0a0200) is
attempting to boot the database /export/home/sky/wombat even though
Derby (instance 80000000-00d2-3265-8abf-000a0a0a0200) may still be
active. Only one instance of Derby
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 Derby, then restart
one instance of Derby 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 Derby system can delete the db.lck
file.
If the "gemfirexd.distributedsystem.forceDatabaseLock" property is set to true
then this default behavior is altered on systems where Derby cannot
prevent this dual booting. If the to true, then if the platform does
not provide the ability for Derby to guarantee no double boot, and
if Derby 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
Derby system. Also note that if the db.lck file is removed by
hand while a VM is still accessing a gemfirexd.distributedsystem, then there
is no way for Derby 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:
