Confluence does not start, and gives a "there may be a configuration problem in your confluence.cfg.xml file." message.


Confluence allows you to define custom hibernate settings, and checks them on startup. This message indicates that you may have misconfigured your settings.


Revert any custom settings you may have set in the confluence.cfg.xml file in your Confluence installation directory that start with hibernate. The following properties and values should be present by default:

    <property name="hibernate.c3p0.acquire_increment">1</property>
    <property name="hibernate.c3p0.idle_test_period">100</property>
    <property name="hibernate.c3p0.max_statements">0</property>
    <property name="hibernate.c3p0.min_size">0</property>
    <property name="hibernate.c3p0.timeout">30</property>
    <property name="hibernate.connection.isolation">2</property> (in 3.5.6 and later)
    <property name="hibernate.setup">true</property>

The following properties should be present, but will have varying values (indicated by ?) depending on your installation:

    <property name="hibernate.c3p0.max_size">?</property>
    <property name="hibernate.connection.driver_class">?</property>
    <property name="hibernate.connection.password">?</property>
    <property name="hibernate.connection.url">?</property>
    <property name="hibernate.connection.username">?</property>
    <property name="hibernate.database.lower_non_ascii_supported">?</property>
    <property name="hibernate.dialect">?</property>
