Configuration

This page is part of the Getting Started Section. It gives some insight into the configuration of BaseX.

Configuration Files

BaseX maintains some configuration files, which are stored in the project’s Home Directory:

  • .basex contains all options that are relevant for running the server or standalone versions of BaseX.
  • .basexgui defines all options relevant to the BaseX GUI.
  • .basexhistory contains commands that have been typed in most recently.
  • An empty .basexhome file can be added to a directory to mark it as home directory.

Note that:

  • Depending on your OS and configuration, files and folders with a '.' prefix may be hidden.
  • In the Web Application context, options can be defined in the web.xml file.

Home Directory

As BaseX is distributed in different flavors, and as it may be started from different locations, it dynamically determines its home directory:

  • First, the Java system property org.basex.path is checked. If it contains a value, it is chosen as directory path.
  • If not, the current user directory (defined by the system property user.dir) is selected if the .basex or .basexhome file is found in this directory.
  • If not, the application directory (the folder in which BaseX is located) is chosen if one of these two files is found in that directory.
  • In all other cases, a basex subdirectory in the user home directory will be returned. The user home directory is retrieved via the HOME environment variable, or (if unassigned) the Java system property user.home.

If BaseX is used in an embedded environment (such as a servlet in a Web Application), it may not immediately be clear which directory was picked. You can run the XQuery expression Q{java:org.basex.util.Prop}HOMEDIR() to find out.

Database Directory

Databases consists of several binary files. These are located in a directory named by the name of the database. The database root directory is named data.

The database path can be changed as follows:

  • GUI: Choose OptionsPreferences and choose a new database path.
  • General: edit the DBPATH option in the .basex configuration file

Note: Existing databases will not automatically be moved to the new destination.

Log Files

Log files are stored in text format in a .logs subdirectory of the database folder (see Logging for more information).
