Explain oracle instance...

Answer / Anurag Chaturvedi

An Oracle instance is the runtime environment of an Oracle database. It consists of a SGA (System Global Area) and one or more background processes that manage various tasks such as recovery, memory management, and file I/O. The Oracle instance communicates with clients through SQL*Net protocol.nnWhen you start the database, both system global area (SGA) and background processes are allocated, creating an Oracle instance.
