問題1: 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?
A. Deploy an application-scoped Data Source module with each application.
B. Deploy a Data Source system module and assign it multiple JNDI names.
C. Deploy each department's application to its own WebLogic server.
D. Deploy a Data Source system module for each department's application.
正解: B
