Configuring the database

This section describes how to configure the database connection, if required.

By default, an H2 database is configured and created when the application first starts. The H2 database named gn.h2.db is created:

  • In the jetty folder of the GeoNetwork application folder when using the ZIP distribution;

  • In the bin folder of Tomcat when deploying the WAR on Tomcat (started using startup.sh).

Note

You don’t need to configure the database if you are happy with the local H2 database. Only change the configuration if you wish to store the data on a remote database.

To modify the database configuration, first check which type of database is used. Depending on the node (default node name is srv) check the node configuration file WEB-INF/config-node/srv.xml. Choose the database type to use.

Then update the WEB-INF/config-db/jdbc.properties file with connection information.

The database default structure will be created by the application on startup.

To see more details about the database connection and queries, the log can be switched to DEBUG level in source file web/src/main/webapp/WEB-INF/classes/log4j.xml (or see Serveur de catalogue > Log level).
