I already have oracle 8.1.7.4 running on windows 2000, and I also have namesserver running on the same machine. I just install Oracle 9i on this same machine and I create a new instance on the 9i, the question is:

1. Can I use the namesserver of 8i and just load the new instance of 9i???

2. Can I have two namesserver (8i and 9i) on the same mahince????
3. Can I have only one namesserver and use it for 8i and 9i instance or vice vesus????

thanks
