Connecting to SQL 2005 from Oracle error

Question

I have an Oracle Database and SQL Database on the same server and wants to use odbc to connect to the SQL 2005 database and query tables of my choice.
I did configured the ODBC correctly and called the DSN TSH_ARCHIVE. I have tested it and it works great. But each time I run the following query I get error:
SQL> select count(*) from BALANCES_HS@tse_archive;
select count(*) from BALANCES_HS@tse_archive
ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specified
Any suggestion and help will be greatly appreciated.

Hi,
Thanks for the files.
There are some problems with the configuration.
listener.ora -
LISTENERTSE_ARCHIVE =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST = xxxxx.ita.doc.gov)(PORT=1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=TSE_ARCHIVE)
(ORACLE_HOME=J:\app\product\11.1.0\db_2)
(PROGRAM=hsodbc)
(SID_DESC=
(SID_NAME=tpisdb06)
(ORACLE_HOME=J:\app\product\11.1.0\db_2)
This should be -
LISTENERTSE_ARCHIVE =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST = xxxxx.ita.doc.gov)(PORT=1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
SID_LIST_LISTENERTSE_ARCHIVE =
(SID_LIST=
(SID_DESC=
(SID_NAME=TSE_ARCHIVE)
(ORACLE_HOME=J:\app\product\11.1.0\db_2)
(PROGRAM=dg4odbc)
(SID_DESC=
(SID_NAME=tpisdb06)
(ORACLE_HOME=J:\app\product\11.1.0\db_2)
The SID_LIST_LISTENER needs to match the actual listener name and the program for 11g DG4ODBC is called dg4odbc and not hsodbc.
tnsnames.ora -
TSE_ARCHIVE =
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = TSE_ARCHIVE)(PORT=1521))
(CONNECT_DATA =
(SERVICE_NAME = TSE_ARCHIVE)
(HS=OK)
The HOST name - TSE_ARCHIVE does not match the HOST in the listener, so it should be -
TSE_ARCHIVE =
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = xxxxx.ita.doc.gov)(PORT=1521))
(CONNECT_DATA =
(SERVICE_NAME = TSE_ARCHIVE)
(HS=OK)
I've changed the actual name to xxxxx so replace that with the name in the original file.
Change the files, stop and start the listener then try again.
If you still have an ora-12154 error then send the output from the following SQL -
select db_link, host from user_db_links; <=== as the user getting the error
and
select db_link, host from dba_db_links; <===== as a DBA user
