Component org.nuxeo.runtime.datasource

Documentation

Component use to register datasources.

Example contribution:

    <datasource driverClassName="org.apache.derby.jdbc.EmbeddedDriver"
        maxActive="20" maxIdle="5" maxWait="10000" name="jdbc/foo">
        <property name="url">jdbc:derby:/home/db;create=true</property>
        <property name="username">nuxeo</property>
        <property name="password">nuxeo</property>
    </datasource>

Or, for a XA datasource:

    <datasource maxActive="20" maxIdle="5" maxWait="10000"
        name="jdbc/foo" xaDataSource="org.apache.derby.jdbc.EmbeddedXADataSource">
        <property name="databaseName">/home/db</property>
        <property name="createDatabase">create</property>
        <property name="user">nuxeo</property>
        <property name="password">nuxeo</property>
    </datasource>

The allowed attributes of a datasource

element are:

name the JNDI name (for instance jdbc/foo )
driverClassName the JDBC driver class name (only for a non-XA datasource)
xaDataSource the XA datasource class name (only for a XA datasource)

To configure the characteristics of the pool:

maxActive the maximum number of active connections
minIdle the minimum number of idle connections
maxIdle the maximum number of idle connections
maxWait the maximum number of milliseconds to wait for a connection to be available, or -1 (the default) to wait indefinitely
... see org.apache.commons.dbcp.BasicDataSource setters for more.

To configure the datasource, individual property sub-elements must be used. For a non-XA datasource, url

, username

and password

are commonly used. For a XA datasource, the properties are done according to the JavaBean setters of the datasource, see the documentation for your JDBC driver for more.
