Hello all,
I'm a newbie to the database world. I've downloaded Oracle 10g XE and this is working fine. I've also downloaded Microsoft SQL Server 2008 R2 Trial Version and I wish to connect it to this.
I've installed Oracle Instant Client and unzipped it in ORACLE_HOME. When I add the ODBC in Data Sources and test this I get an error:
ORA 15154 - TNS could not resolve connect identifier
I've amended the listener.ora and tnsnames.ora files and also the environment varialbe TNS_ADMIN to point to /ORACLE_HOME/Network/Admin. I've also added ORACLE_HOME to the PATH variable. I've done a tnsping and lsnrctl status in the Command Line and all looks to be fine.
TNS_ADMIN:
C:\oraclexe\app\oracle\product\10.2.0\server\NETWORK\ADMIN
PATH:
C:\oraclexe\instantclient_11_2;C:\oraclexe\app\oracle\product\10.2.0\server\bin
My listener.ora and tnsnames.ora files are as follows:
-----
tnsnames.ora
-----
h1.OracleXE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.66)(PORT = 1521))

(SERVICE_NAME = XE)
(HS = OK)
)
)
EXTPROC_CONNECTION_DATA =

(CONNECT_DATA =

ORACLR_CONNECTION_DATA =

Any help would be very much appreciated. I've tried everything but no success at all.
