Blackboard Performance Engineering

The Blackboard Academic SuiteTM and Quest Software Monitor and Diagnose Database Performance Issues of Your High-performance e-Learning Applications

BLACKBOARD PERFORMANCE ENGINEERING

Academic IT professionals who work with the Blackboard Academic Suite™ spend a great deal of time maintaining control over their deployment environments due to constant change. The Blackboard Academic Suite is an enterprise application supporting several deployment environments running Microsoft® Windows® operating systems with a Microsoft SQL Server™ database or Red Hat® Enterprise Linux® and Sun Solaris™ operating systems running with an Oracle® database. There are many factors that impact the environment including hardware upgrades and maintenance, software upgrades and service packs, as well as changes in adoption and growth. The database and its underlying code are at the core of your Blackboard Academic Suite solution. The assignment of managing an enterprise database can be daunting to database and system administrators alike.

A primary function of a database administrator is to maintain the health and stability of the database, ensuring optimum efficiency and performance while managing the impact of database changes. Database administrators are responsible for: • Installing and configuring databases • Maintaining the database—managing back-ups, extending data files and storage, adding and removing

database users, auditing, and reviewing the database for security problems • Ensuring the performance of the environment and keeping database response times within required service

levels • Installing new software, service packs and patches specifically for the database and testing these installations

before deploying to production • Imposing standards and procedures for data storage and growth • Acting as a liaison to systems administrators, analysts, and programmers to add new applications or upgrades

to the database

Quest Software’s Spotlight® discovers performance bottlenecks in your database environment both in real-time and historically. Spotlight is extremely flexible and capable of providing performance diagnostics on the Oracle, Oracle RAC and SQL Server database platforms, as well as DB2, Sybase and MySQL. Spotlight cuts through the complexity of the database environment and graphically portrays the performance status for administrators, enabling familiarity with the environment regardless of experience level. Spotlight automatically sets a baseline of normal activity for each database environment and calibrates its displays accordingly. You can also set thresholds and alarms relative to these baselines. Blackboard’s Performance Engineering and Architecture team uses Spotlight in house daily, including Spotlight on Oracle, Spotlight on Oracle RAC and Spotlight on SQL Server.

The responsibilities of database administrators are becoming more and more diversified with the addition of technologies to the IT business unit. Business-critical databases include more than just Oracle with the expansion of Oracle RAC and the rapid growth of Microsoft SQL Server in the production environment. Each of these environments comes with its own specific performance concerns, which can be overwhelming without the proper tools to quickly diagnose performance issues and empower administrators to bring issues to resolution with minimal impact on service levels.

For the Oracle environment, Spotlight on Oracle: • Provides a visual representation of process flows within Oracle instances, allowing observation of database

activity in real time. • Displays all important information in one place, including actual database and operating system activity. • Allows historical playback of Oracle performance to understand and troubleshoot past performance issues. • Visually identifies bottlenecks and provides extensive drill-down capabilities to understand the root of a

performance issue. • Increases the effectiveness of staff with expert help delivered with the product. • Enables you to see all critical database components on one screen. • Displays the details of problem areas including top sessions, inefficient SQL, locks, latches, wait events and disk I/O. • Measures the performance and efficiency of ASM (Automatic Storage Management). • Provides detailed performance metrics and alarming for Oracle performance issues.

Oracle databases existing in a Real Application Cluster environment offer another layer of complexity to monitoring performance of the database by including cluster-related performance concerns. Spotlight on Oracle RAC removes this layer of complexity.

Spotlight on Oracle RAC provides all the functionality of Spotlight on Oracle, as well as additional functionality specifically for RAC: • Provides a visual representation of process flows within Real Application Clusters, allowing observation of

activity in real time. • Displays everything important in one place, including actual database and operating system activity on each node. • Diagnoses RAC performance from three key perspectives: o Individual node o Cluster as a single database o Interconnect load, latency and overhead • Visually identifies bottlenecks and provides extensive drill-down capabilities to understand the root of a

performance issue. • Increases the effectiveness of staff with expert help for RAC that’s delivered with the product. • Enables you to see all critical RAC components on one screen. • Provides an historical record of performance of the cluster for analysis and playback of past performance

problems. • Provides detailed performance metrics and customized alarming for RAC environments.

In the Microsoft SQL Server environment, Spotlight on SQL Server facilitates the discovery, diagnosis and resolution of SQL Server-related performance issues in single SQL Server database environments, as well as clustered, enterprise-level environments.

Spotlight on SQL Server helps database administrators: • View and trace all sessions in a single interface.• See performance of critical IT components at a glance – Spotlight shows both database and operating system

activity.• Improve responsiveness to potential bottlenecks with real-time alerts.• Simplify database management tasks by eliminating the need to write diagnostic SQL scripts.• Monitor performance of multiple SQL Server databases simultaneously.• Promote the experience levels of staff through a built in expert knowledge base.

Quest Software’s Spotlight enables you to meet the demands of managing and growing the Blackboard Academic Suite database environment by providing the ability to diagnose and resolve performance issues occurring both in real-time and historically. Spotlight also offers the flexibility of performing these tasks on all major database platforms, allowing administrators to be immediately productive regardless of their platform expertise.
