RE: Use SQL*Plus 10g to connect to 9i databases

Stephen,    

The error means that you've connected to a listener at the host/port specified in your connect string, but the listener you've connected to doesn't recognize the value of SERVICE_NAME specified in the connect string. On the database server, where the listener is running, if you do a 'lsnrctl services', is the service you're trying to connect to listed there? Also on the database server, what if you connect to the database with "/ as sysdba", and do 'alter system register;"? Then try the lsnrctl command again, is the service listed? Did that fix the problem? If not, are there multiple listeners on that database server? Maybe you're connecting to the wrong one, and it doesn't support that service?    

Hope that helps,  

-Mark

Subject: Use SQL*Plus 10g to connect to 9i databases

SQL*Plus 10.2.0.1 is installed on my laptop and I want to use it to connect to as many databases as I can. (mainly 9i variants) I have updated the tnsnames.ora in the 10g home to contain all the entries, and when I use the command-line tnsping, it resolves the names, but when I use 10G SQL*Plus for Windows, it tells me  

ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor

SP2-0640: Not connected

What am I missing?  

Bonus points if you can tell me how to connect 10g EM Database Control to other databases (i.e. especially 9i)

TIA
