Database Connections

If the OracleAS TopLink Mapping Workbench encounters problems communicating or logging into the database, you should:

• Ensure that the driver class, login name, password, and JDBC database URL are correct.

• Verify that your system classpath includes all files (for example, native .dll files) required by the driver.

• Verify that your OracleAS TopLink classpath includes all classes and files (for example, .zip or .jar) required by the driver.

• Consult with your database administrator and confirm that the:

  • Database server is setup correctly

  • Database permissions are set correctly

  • Database has enough available connections
