All Implemented Interfaces:

DataBaseService, DataBaseServiceImplMBean, Service

public class DataBaseServiceImpl

extends AbsServiceImpl

implements DataBaseService, DataBaseServiceImplMBean

DatabaseService acts as a factory for the DataSource objects. Its goal is to create such objects and to register them in JNDI

Author:

Philippe Durieux Contributor(s): 00/18/04 Jun Inamori (j-office@osa.att.ne.jp) New implementation of unbindDataSources for closing correctly all connections at server shutdown. 03/01/14 Adriana Danes Highlight Configuration properties Change createDataSource() signature : take additional argument, the datasource name Manage binded datasources (mapping of jndi name to datasource name) Use datasource name for naming MBeans (instead of jndi name) Modify MBean methods to take into account the previous points.

DataBaseServiceImpl

public DataBaseServiceImpl()

Method Detail

doInit

public void doInit(javax.naming.Context ctx)
            throws ServiceException

Initialization of the DataBase service. Configuration information is passed thru a Context object.

Overrides:

doInit in class AbsServiceImpl

doStart

public void doStart()
             throws ServiceException

Starting DataBase service Initialization of the service is already done.

Overrides:

doStart in class AbsServiceImpl

doStop

public void doStop()
            throws ServiceException

Stopping DataBase service Unbind DataSources

Overrides:

doStop in class AbsServiceImpl

createDataSource

public void createDataSource(java.lang.String datasourceName,
                             java.util.Properties dsd)
                      throws java.lang.Exception

Creates a ConnectionManager (implementation of sql.dataSource).

Specified by:

createDataSource in interface DataBaseService

Parameters:

datasourceName - - datasource name

dsd - - a set of properties that describes a dataSource and the ConnectionPool

If datasource.factory is set, we create a JonasXAPoolDataSource. If not set, we create an old fashioned ConnectionManager

traceJdbc

public void traceJdbc()

Propagation of the new configuration of the trace functionnalities in the driver

unbindDataSources

public void unbindDataSources()
                       throws javax.naming.NamingException

Unbind dataSource names from the Naming

Specified by:

unbindDataSources in interface DataBaseService

getXAPoolDataSource

public static JonasXAPoolDataSource getXAPoolDataSource(java.lang.String dsname)

get the XAPoolDataSource matching the DataSource name

getConnectionManager

public ConnectionManager getConnectionManager(java.lang.String dsname)
