Error ORA: 12154 Creating 64 bit DSN

  • ORA: 12154 TNS: Could not resolve the connect identifier specified.

    The only part that I was not sure about was the TNS Service Name as specified in the following and I chose the SERVICE_NAME initially and subsequently verified

    In this dialog in the text entry box labeled TNS Service Name, type the <SERVICE_NAME> found in the tnsnames.ora file.

    NoteFor example, here’s a typical path to the tnsnames.ora file: C:\oracle\product\10.1.0\Db_1\NETWORK\ADMIN. In this file there are entries similar to the following: ORCL = (..(CONNECT_DATE = (...(SERVICE_NAME = orcl)))

    :

    I used the same TNSNAMES.ORA and SQLNET.ORA from the 32 bit Client in SSIS and I was able to create connections to Oracle and Load Several Tables from Oracle to SQL Server.

    I have created hunders of DSN's to Oracle 8, 9 & 10 Clients but it has been a few years.

    Any help would be greatly appreciated.

  • I forgot to create the TNS_NAMES Environmental Variable.

    I also had to reboot before I could test the DSN.
