| 5 | [[H2>>http://h2database.com]] is a fast, free, in-memory or disk-based java database. | ||
| 6 | |||
| 7 | Follow these instructions to use it with XWiki: | ||
| 8 | |||
| 9 | * H2 is a very simple database to configure as you don't need to install nor to start it before being able to use it. It comes as a single JAR file named ##h2*.jar##. You'll need to [[download this JAR>>http://www.h2database.com/html/download.html]] and copy it in your ##WEB-INF/lib## directory. | ||
| 10 | * Once this is done, you need to configure XWiki to use H2 and to tell it where the database files will be created. To do this, edit the ##WEB-INF/hibernate.cfg.xml## file where you have expanded the XWiki WAR file and uncommented the H2 part. If you're using an old version of XWiki you won't find a commented out section for H2. In this case, use the following:((( | ||
| 11 | {{code language="xml"}} | ||
| 12 | <property name="connection.url">jdbc:h2:${environment.permanentDirectory}/database/xwiki</property> | ||
| 13 | <property name="connection.username">sa</property> | ||
| 14 | <property name="connection.password"></property> | ||
| 15 | <property name="connection.driver_class">org.h2.Driver</property> | ||
| 16 | <property name="dialect">org.hibernate.dialect.H2Dialect</property> | ||
| 17 | {{/code}} | ||
| 18 | ))) | ||
| 19 | |||
| 20 | = Using a JDBC DataSource = | ||
| 21 | |||
| 22 | {{code language="xml"}} | ||
| 23 | <property name="connection.datasource">java:comp/env/jdbc/XWikiDS</property> | ||
| 24 | <property name="dialect">org.hibernate.dialect.H2Dialect</property> | ||
| 25 | {{/code}} | ||
| 26 | |||
| 27 | = Using a remote H2 instance = | ||
| 28 | |||
| 29 | {{code language="xml"}} | ||
| 30 | <property name="connection.url">jdbc:h2:tcp://remotehost/xwiki23</property> | ||
| 31 | {{/code}} | ||
| 32 | |||
| 33 | On the H2 side, here's one way to have H2 running on a remote machine: | ||
| 34 | |||
| 35 | {{code language="bash"}} | ||
| 36 | java -cp ./h2-1.2.136.jar org.h2.tools.Server -web -tcp -tcpAllowOthers -baseDir /var/spool/javadb/h2 | ||
| 37 | {{/code}} | ||
| 38 | |||
| 39 | Thus any database you create will be stored in this location, so with the above example you will have a database called ##/var/spool/javadb/h2/xwiki23##. |
