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.
