Tuning and Troubleshooting Transactional Replication - Kendal Van Dyke

At some point in every DBA's career, they are probably asked to work with transactional replication. But most DBAs don't look under the covers after they've walked through the setup wizards. Even worse, when something breaks, you don't know where to look and end up trying to figure out what's wrong and how to fix it. In this session, we take a deeper look at setting up, monitoring, and calibrating transactional replication. We also share troubleshooting tricks and tips gleaned from years of experience working with high-volume, multiple-datacenter topologies.
