Scenario: You have made the decision to migrate all your operations onto WebLogic Server. An application has been chosen from each department for the initial phase of migration one from each of Sales, Marketing, Accounts, and Customer Service. The applications will be deployed as individual EAR files to a cluster of WebLogic Server 9.x instances, each with a pool of connections to an Oracle 10g database that provides corporate and departmental data services. The database team hopes to upgrade the database to use Oracle RAC (Real Application Clusters) shortly, which will require you to configure multiple sets of connections. Connectivity to the existing Service Engineer Dispatch system is via a JMS message bridge. When a service engineer calls in with a report, a message is sent via JMS to the Customer Service application deployed in WebLogic Server. The customer record in the Customer Service database must be updated with details from the message. It is important that the message is not lost because the call management system is not able to resend messages. To address this, the Customer Service application is accessing a persistent JMS Queue using an XA compatible connection factory. In the future, each department will have its own schema within the Oracle database and the developers are writing their code with this in mind. However, for now, it has been decided to store all data in a single, company-wide schema. Which of the following approaches will make a future move to multiple schema simple, while making the most efficient use of resources today?

Answer(s)

1. Deploy an application-scoped Data Source module with each application.
2. Deploy a Data Source system module and assign it multiple JNDI names.
3. Deploy each department's application to its own WebLogic server.
4. Deploy a Data Source system module for each department's application.

Deploy a Data Source system module and assign it multiple JNDI names.
