If I change DBID will it effect anything. If I duplicate the database with same database name. Does it have same DBID or new one.

The docs talk all about this.

If you do not change it, it has the same DBID.  If done properly it should not effect anything.

Check your versions....

nid you ran was 9.2 and the database is possibly 10gR2?

This is the problem with getting all your answers from a site like this and not taking the time to read the docs and actually learn.

You've asked enough questions about multiple Oracle homes that selecting the correct ORACLE_HOME and PATH should no longer be an issue.

No.  That would be a duplicate question.  We can either continue like this or I can reopen this question if you wish.

Give me a minute on the error.

>>So nid target=/

This will connect to the instance set by ORACLE_SID.  Verify the SID is correct and please try it.

>>getting the above error

The timeout error can be caused by a few things but it is typically caused by a firewall issue.  

Verify the ipaddress/host for oracle10 in your tnsnames.ora and listener.ora files and make sure everything is set up properly.

I have everything on a single laptop. so It is not necessary to verify ipaddress for listener or tnsnames.ora file right. Anyway its working fine with nid target=/. so do I need to close the question again or just leave it
