- Develop data access applications
We can use data access applications to manipulate data from outside sources for use within the application serving environment.- Example: Setting client information with the setClientInformation(Properties) API
We can set WebSphere Application Server client information on connections to pass that information to the database with this API.- Change the error detection model to use the Exception Checking Model
The error detection model has been expanded and the data source has a configuration option used to select the exception mapping model or the exception checking model for error detection. This configuration option allows the Error Detection Model to comply with JDBC 4.0.- Exceptions pertaining to data access
All enterprise bean container-managed persistence beans under the EJB 2.x specification receive a standard EJB exception when an operation fails. JDBC applications receive a standard SQL exception if any JDBC operation fails. WAS v8.5 provides special exceptions for its relational resource adapter (RRA), to indicate the connection currently held is no longer valid.
