User Interface Enhancements
Replication wizards
40% fewer pages
Improved default values and auto- detection
Less branching
New Subscription Wizard
Replaces the Push Subscription Wizard and Pull Subscription Wizard
Allows you to define multiple subscriptions with different properties at the same time
Replication Management
Initializing a subscriber
Backup and restore
Copying a database
Dynamic snapshots
Resuming snapshot transfers Replicating DDL statements
Allowing anonymous subscriptions for all publications
Performance and Scalability
Precomputed partitions Updates to unique keys
Transactional parallelism —
independent agent option used by default
Download only articles — to reduce change tracking metadata
Reduced contention on reporting subscribers
Use snapshot isolation level
Use snapshots
Replication Monitor
Independent from SQL Server Management Studio
Passive monitoring
Define acceptable performance figures Minimize monitoring impact
Merge replication
Article level statistics
Upload and download statistics
Transactional replication — real-time monitoring with tracer tokens
Other Enhancements
Merge replication concurrency
enhancements — guaranteed delivery of logical records
Programming changes — release of RMO
Replication of more types of objects
.NET UDTs
Assemblies
Lesson: New Types of Replication
Heterogeneous Replication
Peer-to-Peer Transactional Replication HTTP Replication
Heterogeneous Replication
Use Oracle v8 and later databases as the publisher in a replication system
Snapshot replication — no impact on Oracle database
Transactional replication
Triggers and tracking tables added to Oracle database
Log Reader Agent transfers changes to SQL Server Distributor and Distribution Agent transfers
changes to subscribers

Differences between SQL Server and Oracle
Use of Oracle tools
