Administration Tasks for Analysis Services Tutorials
This article covers essential administration tasks for Microsoft SQL Server Analysis Services (SSAS). Effective administration is crucial for maintaining the performance, security, and availability of your Analysis Services environment.
Key Administration Areas
1. Security Management
Securing your Analysis Services data is paramount. This involves managing user roles, permissions, and access to cubes and dimensions.
- Role-Based Security: Define roles with specific permissions to control access to data at various levels (database, cube, dimension, cell).
- User and Group Management: Integrate with Windows authentication or SQL Server authentication to manage user access.
- Auditing: Implement auditing to track who accessed what data and when.
2. Backup and Recovery
Regular backups are vital for protecting your Analysis Services data against loss or corruption.
- Full Backups: Back up the entire Analysis Services database.
- Incremental Backups: For large databases, incremental backups can save time and space.
- Transaction Log Backups: While Analysis Services is not a transactional system in the same way as SQL Server relational databases, proper backup strategies are still essential.
- Recovery Models: Understand the different recovery options available.
3. Performance Monitoring and Tuning
Monitoring the performance of your Analysis Services instances helps identify bottlenecks and optimize query response times.
- SQL Server Management Studio (SSMS): Utilize SSMS for monitoring server activity, query performance, and resource utilization.
- Performance Monitor (PerfMon): Use PerfMon counters specific to Analysis Services to track key performance indicators (KPIs).
- Query Performance Analysis: Identify slow-running queries and analyze their execution plans.
- Caching: Configure query and data caches to improve response times.

4. Database Management
Managing the Analysis Services databases includes tasks like deployment, configuration, and maintenance.
- Deployment: Deploy cube and dimension projects from Visual Studio or other development tools.
- Processing: Schedule and manage the processing of Analysis Services objects to refresh data.
-- Example: Processing a database via XMLA
ALTER DATABASE [YourDatabaseName] PROCESS
Asynchronous
5. Server Configuration
Adjusting server properties can significantly impact performance and resource usage.
- Memory Configuration: Fine-tune memory allocation for caching and processing.
- Concurrency Settings: Configure the number of concurrent queries the server can handle.
- Logging: Adjust logging levels for troubleshooting.
Best Practices for Analysis Services Administration
- Regularly review security configurations.
- Implement a robust backup and disaster recovery plan.
- Proactively monitor server performance and resource utilization.
- Keep Analysis Services up-to-date with the latest service packs and cumulative updates.
- Document all administrative procedures and configurations.
By implementing these administration tasks and best practices, you can ensure a stable, secure, and high-performing Analysis Services environment.
