Resource manager

The Oracle database resource manager (the Resource Manager) enables us to optimize resource allocation among the many concurrent database sessions. When database resource allocation is done by the operating system, we may encounter the following problems with workload management:

Excessive overhead results from the operating system context by switching between Oracle database server processes
The operating system de-schedules database servers while they hold latches, which is inefficient
The operating system distributes resources equally among all active processes and cannot prioritize one task over another
Inability to manage database specific resources, such as parallel execution servers and active sessions

Susan Harper

Sue Harper was a senior school mathematics and science teacher by profession. It was this teaching qualification that opened the door to Oracle in South Africa, where Sue started as a SQL, PL/SQL, SQL Forms, and Reports instructor in 1992. Before long she'd added Oracle Designer to her repertoire and soon left for the UK, to join the Designer curriculum development team. Sue was a course writer and then product manager for Oracle Designer for many years, traveling extensively meeting customers and training Oracle staff and instructors. Sue was later product manager for Oracle JDeveloper working with database and modeling tools in that product. Sue is currently product manager for Oracle SQL Developer, SQL Developer Data Modeler, and SQL Developer Migrations. Based at home, Sue works with her team, scattered around the world and customers, running web-based training sessions or helping with individual queries. She frequently attends conferences where she presents SQL Developer material and works with customers on their queries. Sue lives in West London, where she enjoys walking with her camera and her dog in the extensive local parks and further afield throughout the UK.
