本文介绍了uPortal系统中两种数据源配置方式：通过JNDI获取数据源和非JNDI方式使用连接池的数据源配置。对于非JNDI方式，详细说明了如何通过配置文件设置连接池的具体参数。

uPortal两种数据源:
1、JNDI 方式根据portal.properties文件中的org.jasig.portal.RDBMServices.getDatasourceFromJndi参数来决定

org.jasig.portal.RDBMServices.PortalDatasourceJndiName指定默认数据名“PortalDb”
系统用ds = (DataSource)envCtx.lookup("jdbc/" + name);得到数据源然后加到map中去。

2、非JNDI方式(org.jasig.portal.RDBMServices.getDatasourceFromJndi指定为false)

系统会读取/properties/rdbm.properties文件
jdbcUsePool=true来设置是否使用连接池
portal.properties中的org.jasig.portal.PooledDataSourceFactory.implementation 指定数据源工厂
接口类为
public interface IPooledDataSourceFactory {

    /**
     * Creates a {@link DataSource} that is backed by a connection pool.
     *
     * @param driverClassName The class name of the jdbc driver to use.
     * @param userName The username to connect to the database with.
     * @param password The password to connect to the database with.
     * @param url The url to locate the database with.
     * @param maxActive Maximum number of dB connections in pool. Set to 0 for no limit.
     * @param maxIdle Maximum number of idle dB connections to retain in pool. Set to 0 for no limit.
     * @param maxWait Maximum time to wait for a dB connection to become available in ms, in this example 10 seconds. Set to -1 to wait indefinitely.
     * @return A {@link DataSource} that is backed by a connection pool.
     */
    public DataSource createPooledDataSource(String driverClassName, String userName, String password, String url);
}
