Creating a DataSource 

Use

In certain scenarios – for example, if you need to use a different database from the default one – you need to create a new DataSource.

Activities

Registering a DataSource in the Visual Administrator

You can register a DataSource in the Visual Administrator using the functions provided by the JDBC Connector Service. For more information, see:

·        Creating a DataSource with JDBC 1.x Driver

·        Creating a DataSource with JDBC 2.0 Driver

Deploying DataSource with an Application or a Library

The SAP J2EE Engine supports deployment of DataSource objects with an application or a library.

·        Deploying DataSource with an application

You have to include an XML definition of the DataSource in the META-INF directory of the application archive file (EAR). For more information about the format of the XML file, see data-sources.dtd in the Reference Manual. You can use the DataSource when the associated application is started.

·        Deploying DataSource with a library

You can include a DataSource deployment descriptor in a library archive file (SDA) and deploy it on the SAP J2EE Engine. Unlike the case when you deploy the DataSource with an application, in this scenario the DataSource becomes functional when the JDBC Connector Service is started.

To deploy a DataSource in an SDA, you have to include the XML that describes the DataSource in the ../server/descriptors directory of the library SDA.

You can also deploy an alias for an existing DataSource with your library. To do this, you have to include a relevant XML file in the ../server/descriptors directory of the SDA. For more information about the format of the XML file, see data-source-aliases.dtd.
