You Will Learn How To
- Leverage SQL Server technologies to achieve high-availability database solutions
- Design a Service Level Agreement that matches business requirements
- Plan, prepare and install a SQL Server failover cluster
- Maintain a warm standby server with log shipping
- Mirror a database to ensure instant failover
- Employ peer-to-peer transactional replication as a high-availability solution
Course Benefits
SQL Server provides a full range of technologies that allow organisations to reduce downtime and maintain high levels of availability. In order to achieve these goals, an enterprise database administrator must implement failover clustering, log shipping, database mirroring and peer-to-peer transactional replication. This course offers enterprise SQL Server administrators the skills to maintain a large number of constantly available database servers.
Who Should Attend
Anyone involved in planning, supporting or implementing a high-availability solution with SQL Server. Course 138, "
SQL Server 2008 Database Administration", or equivalent experience, is assumed.
