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 file. If you ever move the log manually, you will need to alter the entry in If you move the log back to the default location, remove the logDevice entry from the 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:
