What is the difference between database server and database instance?

[Anshu_Anand_]

Dear All,

1. Can anyone explain difference between Database instance and database server

2. How database servers are discovered. i know about database instances but database servers i have no clue.

 

[Anshu_Anand_]

So we cannot discover database servers.

and also i would like to know, these database instances run on database servers
or the database servers run on database instance?

sorry for the silly question, but i am confused.

Hi Anshu,

Database instance runs on Windows Servers/Servers and depends on Database servers.

Thanks,
Ashutosh

(1) First there is a VM/Physical Server - Server Class

(2) Then You Install DB software on Given Server - S/W Installed on Server

(3) After Installation You Make DB process/Daemon UP and Running -- This is your DB Instance

Instance Running on Server
