What is the architectural benefit of keeping WebLogic Server transaction log in the database?（）

• A、Oracle does not allow replicating files between data centers, so keeping transaction log in database allows for replication.
• B、Many transactions in WebLogic are database centric, so keeping log in database makes Two Phase Commit protocol possible.
• C、It obviates the need to keep in sync two replication technologies (file and database) between  data centers. The single replication technology is used for frequently changing data.
• D、Transaction log in a file system is extremely slow so it cannot be efficiently replicated.
