In a pooled session, the middle-tier application logs on to the system as a database user and establishes a connection pool. The application has a single set of database privileges. All application end users assume the identity and database privileges of the application.
You can use query banding to:
- Identify end users, who otherwise all appear to the system as the application user.
- Record resource accounting information, such as job number, application, or report type.
- Determine session or request level access priority, by using the query bands as workload management rule criteria.
