Oracle database single instance architecture

Oracle database single instance architecture

 Maine database runs on a single machine we referred to this architecture as the Oracle database single instance architecture this setup involves having one Oracle database instance running on the mission serving its clients 

 The term Oracle database instance simply refers to the combination of memory structure and database process that collectively represent the database service.

 However this Architectire has a significant availability risk.

 If anything goes wrong with the mission that database becomes UN available.
