| How to use an external database? |
| |
| * Supported databases |
| |
| * Derby |
| |
| * MySQL |
| |
| * Postgres |
| |
| * MS SQL Server (with modifications) |
| |
| * Oracle (with modifications) |
| |
| * Configure Continuum |
| |
| There is some information in the installation guides for the {{{../installation/standalone.html} standalone Continuum |
| installation}} and the {{{../installation/tomcat.html} Continuum web application deployed to Tomcat}}. |
| |
| ** Standalone version |
| |
| To use an external database with Continuum standalone, you must configure DataSources in <<<$CONTINUUM_HOME/contexts/continuum.xml>>> |
| |
| %{snippet|id=datasources|url=http://svn.apache.org/repos/asf/continuum/trunk/continuum-jetty/src/main/contexts/continuum.xml} |
| |
| In addition, you must add the JDBC driver to the <<<$CONTINUUM_HOME/lib>>> directory, and update |
| <<<$CONTINUUM_HOME/conf/wrapper.conf>>> to list the driver instead of Derby. For example: |
| |
| ---- |
| wrapper.java.classpath.15=%REPO_DIR%/postgresql-8.4-702.jdbc3.jar |
| ---- |
| |
| If you use MS SQL Server or Oracle, you will need to adjust the |
| <<<$CONTINUUM_HOME/apps/continuum/WEB-INF/classes/META-INF/plexus/application.xml>>> file to change the |
| <<<javax.jdo.option.Mapping>>> value from <<<default>>> to <<<mssql>>> or <<<oracle>>> respectively. Bear in mind that |
| this change will need to be made again across release upgrades. |
| |
| %{snippet|id=mapping|url=http://svn.apache.org/repos/asf/continuum/trunk/continuum-webapp/src/main/resources/META-INF/plexus/application.xml} |
| |
| ** Web Application |
| |
| To use an external database with the Continuum web application, you should configure the DataSource in your container. |
| |
| Make sure the JDBC driver is available in the expected location for your container. |
| |
| If you use MS SQL Server or Oracle, you will need to adjust the |
| <<<WEB-INF/classes/META-INF/plexus/application.xml>>> file in the unpacked web application to change the |
| <<<javax.jdo.option.Mapping>>> value from <<<default>>> to <<<mssql>>> or <<<oracle>>> respectively. Bear in mind that |
| this change will need to be made again across release upgrades. |
| |
| %{snippet|id=mapping|url=http://svn.apache.org/repos/asf/continuum/trunk/continuum-webapp/src/main/resources/META-INF/plexus/application.xml} |
| |
| * Shutdown Procedure |
| |
| When using an external database, it is very important to stop Continuum prior to stopping or restarting the database. |
| Continuum may exhibit unpredictable behavior if the database disappears while it is running, and may not recover |
| once the database comes back up. If this happens, you must re-start Continuum. |
