Question #: 25
Topic #: 2

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

AOracle does not allow replicating files between data centers, so keeping transaction log in database allows for replication.

BMany transactions in WebLogic are database centric, so keeping log in database makes Two Phase Commit protocol possible.

CIt 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.

DTransaction log in a file system is extremely slow so it cannot be efficiently replicated.
