Changing SID

Hello everyone,

I use Oracle 10g R2 on Fedora Core 4.
I was trying to change the SID of my test database.
What I did was:
1- Shutting down the Instance

2- changing ORACLE_SID Environment Variable (I also changed the oracle user's .bash_profile, cause I set all required variables in there)

3- changing the PFILE's name and content (I use SPFILE, but I've created a PFILE from the SPFILE and I've changed its name and content)

4- changing the content of tnsnames.ora and listener.ora

5- creating a new password file with a new name

then:

sqlplus "/ as sysdba"
startup;

and database started successfully.
but, when I was trying to startup oracle's listener, I couldn't..

Here is the error:

)
)

The error is talking about an error in parsing the listener file.
But the file looks alright. I thought maybe something else causing this problem.
Any Idea, please?

Thanks in advance

thats not the way to change a sid / database name.

check the docs for the proper way (hint: nid)

Could you please mention the proper one?

i already did, use nid

Thanks for the answer,

But in the NID's documentation I just found a way to change DBID and DBNAME, not SID.
Please correct me if I'm wrong?

Thanks again

I found my answer. I put it here for record and for those that are quiet confident about thier wrong answer.
The way that I've gone through is correct and I don't need to use NID. The problem was a syntax error in the sqlnet.ora file. That's it.

NID is tool to change the DBID and the DBName, not SID.
