Module 9: SQL Server 2005 Replication

Overview Overview of Replication Enhancements New Types of Replication Configuring Replication

Lesson: Overview of Replication Enhancements User Interface Enhancements Replication Management Performance and Scalability Replication Monitor Other Enhancements

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 Potential issues because of:  Differences between SQL Server and Oracle  Use of Oracle tools

How to Configure Replication Using SQL Server Management Studio Creating a publication — New Publication Wizard Creating a subscription — New Subscription Wizard Synchronizing a subscription

Practice: Creating a Publication Using SQL Server Management Studio In this practice, you will see how to: Start the New Publication Wizard Configure a publication
