I also showed you how to create new replication profiles and how to log an agent's output.
Armed with the information in this article, you're ready to maintain and troubleshoot transactional replication. As with any other ammunition, it is prudent to use care with your power; exercise it only when needed, and don't shoot yourself in the foot!
