A customer needs to implement a Highly Available solution for JMS that has a primary data center  and a backup. Which three steps would you perform when designing your solution?（）

• A、Store Transaction Logs in a database and use Database stores for JMS to make replication  between sites easier.
• B、Use file based Transaction Logs and JMS stores and implement a separate replication solution  for files in addition to database in case database replication fails.
• C、Implement Oracle RAC at each site to provide a highly available solution within each datacenter.
• D、Configure Whole Server Migration to migrate WebLogic Managed Servers from the primary to the secondary site.
• E、Configure Automatic Service Migration for JMS high availability within a datacenter.
