Concurrent managers are components of Concurrent Processing that monitor and run time-consuming, non-interactive tasks without tying up your terminal. Whenever you or your users submit a request to run a task, a concurrent manager processes that request and does the work in the background, giving you the ability to run multiple tasks simultaneously.
Oracle Application Object Library predefines the Internal Concurrent manager, which functions as the "boss" of all other managers. The Internal Concurrent Manager starts up, verifies the status of, resets, and shuts down the individual managers. It also enforces program incompatibility rules by comparing program definitions for requested programs with those programs already running in an Oracle username designated as a logical database.
After installation, the system administrator can create and tailor the concurrent managers as needed. The system administrator chooses the number of requests that each concurrent manager can process simultaneously and what types of requests it can process. Concurrent managers provide total control over the job mix and throughput in your application.
