How do I create two intances in one computer?

I want to create two intance in one computer,but I don't know how to create it and how to set parameter about sql*plus!

please give me some information ,thanks !

What is your operating system?

How to depending on your os.
For eg. on NT you can use the create db or db configuration asst to create a new instance.
logging on to them thru sql*plus you'll do when promted upon by the host/string/service.

You can make as many instances as you wish...(i wouldn't know if there is limit). limitations are your memory/physical disks etc.

My System is Win2k Ads.

maybe you can use oradim.exe. It is usually located in the bin folder.
