The format looks fine, but it sounds like you are putting it in the wrong directory. BTW, you're apparently using Derby Check db. I did place it in the wrong directory and it's working now. Instead, you must create, write, and edit this file yourself.

The file should be in the format created by the java. The following is the text of a sample properties file:. Properties set this way are persistent for the system until changed, until the file is removed from the system, or until the system is booted in some other directory in which case Derby would be looking for derby.

If a database is removed from a system, system-wide properties do not "travel" with the database unless explicitly set again. Verifying system properties:. Derby writes information and error messages to a log file with a default name derby. The properties file contains configuration data and parameters specific to the Derby system. The derby system is not persistent.

We must provide the location of the system at every startup. The Derby system is specified with the derby. If the directory specified in the property does not exist, Derby creates it automatically. If we do not specify the property explicitly, the current directory is used.

The current directory is the value of the JVM user. It is recommended to always specify the derby. The property can be set on the command line, in an environment variable, in a dialog box in case we use an IDE, or in the derby. The derby. It is a simple text file which enables us to configure the entire Derby system, a specific database or a conglomerate. A conglomerate is a table or index in Derby. We can configure several options, such as user authorisation, which databases to boot, the name of the log file, the location of the system directory.

In the embedded mode, the database is started when an application first makes a connection to it. It is possible to configure the Derby system to boot all available databases when it starts with the derby.

When the database has started, a message is written to the derby. We can shutdown a database or an entire Derby system. The first JDBC call shuts down the testdb database. The second call ends the whole Derby system. Note that an SQLExpection is raised when a system shuts down.
