Mutiple DB Instances

Hi,

I have Oracle 8.1.5 on my Windows NT and have created a tablespace and an account. Now the User require me to set up four database instances; (1) Development, (2) QA, (3) Field Data Sanitization and (4) Production on the same machine... Can you give me the steps involved in this?

Thanks

erm you better seperate production from development instance but will your machine have enough resources to support 4 instances?

Right.
If you are still going use the Oracle Database Assistant
