Miscellaneous Processes...


Notes:

Additional processes may be running on your server. These include:
Dnnn – One or more dispatcher processes must be started if the Shared Server mode (formerly called Multithreaded Server or MTS) is desired. Shared servers are useful in environments with thousands of users, many with high think (idle) time. The dispatcher process places a client request on a request queue; the next available shared server process processes the request.
Snnn – One or more shared server processes. This process, shared by more than one user, will act on behalf of a user. For example, a shared server process, like a dedicated server process, will process SQL statements (parse, execute and fetch) and perform physical and logical I/O to access the data a user requests.
RECO – This process cleans up after a failed distributed transaction. Distributed transactions utilize two-phase commit protocol. See the Oracle9i Concepts Guide for more information.
