# Using the logDevice=logDirectoryPath attribute

To specify a non-default location for the log directory, set the `logDevice=logDirectoryPath` attribute on the database connection URL when you create the database.

This attribute is meaningful only when you are creating a database. You can specify `logDevice=logDirectoryPath` as either an absolute path or as a path that is relative to the directory where the JVM is executed.

Setting `logDevice=logDirectoryPath` on the database connection URL adds an entry to the service.properties file. If you ever move the log manually, you will need to alter the entry in service.properties. If you move the log back to the default location, remove the logDevice entry from the service.properties file.

To check the log location for an existing database, you can retrieve the `logDevice=logDirectoryPath` attribute as a database property by using the following statement:

    VALUES SYSCS_UTIL.SYSCS_GET_DATABASE_PROPERTY('logDevice')

For more information, see "logDevice=logDirectoryPath attribute" in the Derby Reference Manual.
