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.
