Oracle Database Discussions

Hello,

I was finally able to successfully install Oracle 10g on my Mac Pro workstation.

Following the installation, I used this command to start the listener:

lsnrctl start

and it responded with this, so I think it started correctly:

However, when I tried to connect from the command line via SQL Plus, or using the SQL Developer GUI, it won't connect. SQL Developer says "ORA-12505, TNS:listener does not currently know of SID given in connect does not currently know of SID given in connect descriptor The connect descriptor ussed by the client was: localhost:1521:ORCL"


When I look at my tnsnames.ora file I see this:

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)


I see the ORCL service there.

So, it seems that I have a TNS Listener started, but for some reason I can't connect to the ORCL service. Can anybody tell me how to connect to the ORCL service?

Thank you!!!!
