Hi All,

I have been having problems to connect to my 10g database using DOS/command prompt window. I 've already connected to that database using SQL*Plus, and it is working ok. I checked my sqlnet.ora, lsitener.ora, and tnsnames.ora, and they seems to be ok as well. I got an ORA-12154 error message.
Can anyone tell me why it is  happening?..any idea?
Thanks.

Did you set ORACLE_HOME, ORACLE_SID and the correct PATH environment variables?

Over the registry?..if so, yes I did it.
This are my entries:
ORACLE_HOME=c:\OracleHomes\db10g
ORACLE_SID=emrep

when you use a command prompt, you need to issue the command:

set ORACLE_SID=<YOUR_SID>

before connecting using command line sqlplus.  you do this for every command window you open.  did you do this?

not oracle_home, oracle_sid.

set ORACLE_SID=EMREP

is EMREP the name of your database?
