problem with listner on a box with 10g and 9i

This is windows XP. I'm doing this at home. So its not urgent.

I have 10g installed. I have a new database. I can login if I go to the command line.

1. I started my listener with lsnrctl, and it listed my 9i databases as active and not my 10g database.
2. My lsnrctl is the 10g version. I looked in Network/admin for 10g and no listener, etc... files existed. However, there are 2 10g listeners listed in my services? How can that be? It looks like its looking at my 9i home.
3. I checked my tnsnames.ora in my 9i home. It has my 10g database listed, but its not 'seen' when I run lsnrctl.
4. It looks like my 10g install, did not create another Oracle home in my registry? Isn't it supposed to do that automatically?
5. I changed my ORACLE_HOME to point to the path of my 10g install and now after I get start listener and try to connect, I get 'no listener'. I changed it back and the problem continues(this may be a combination of things).

Anyone have any idea? I never work with network issues. I read the release notes and followed the instructions for a 10g install.

Another on thing. I run the 10g net manager gui and it only sees my 9i databases. I can't figure out what tnsnames its reading. The one in my 9i home has my 10g database in it.

Right now, my biggest problem is that I'm getting 'no listener', when my listener is started. I checked status in lsnrctl. Received on Sun May 16 2004 - 12:57:16 CDT
