Hi,

I have a fully backup of production database in the last month, and I have using Oracle 8.1.7. I want to known how can I use
this backup to generate a new instance so that I can reproduct some report from the last month data or doing some update
testing
from the backup database with the both production instance and last month instance is opened at the same time. I have tried to
create a new instance by using the oradim and startup the new sid with mount option and then use the alter database function
to change the datafile name to the new directory. After this i also create the local service name and change to listerner. I can
startup the new instance but when i start the production database. I got the error that I can open the database with exclusive.
I do this in Oracle 7.3.4 and it works. But how can i setting it in Oracle 8.1.7. Anyone can help me and many thanks.
