createDataSource

public static javax.sql.DataSource createDataSource(String dataSourceName,
                                                    String jdbcDriverClassName,
                                                    String jdbcUrl,
                                                    String userName,
                                                    String password,
                                                    int initConnCount,
                                                    int maxConnCount,
                                                    int namedPoolCount,
                                                    int namedPoolMaxSize)
                                             throws SQLException

Returns a generic DataSource.

Parameters:

dataSourceName - the internal name of the datasource used to identify it in error logs and exceptions

jdbcDriverClassName - the name of the class that implements the JDBC driver used to create connections for this datasource, e.g., "com.sssw.jdbc.oracle.Driver"

jdbcUrl - connect string for the driver, for example "jdbc:sssw:oracle:heartstopper"

userName - db user name under which to connect to the database

password - password under which to connect to the database

initConnCount - indicates the number of connections with the above username/password that should be opened when the pool is first created

maxConnCount - defines the maximum number of connections that can be opened for the default user by calling getConnection() on a returned datasource object,

namedPoolCount - indicates how many non-default users can be supported. Note that connections for a non-default user are obtained by calling getConnection(username,passwowrd) on the returned DataSource object.

namedPoolMaxSize - defines the maximum number of connections that can be opened for each non-default user
