ORA-12154: TNS:could not resolve the connect identifier specified
 *Cause:  A connection to a database or other service was requested using
 a connect identifier, and the connect identifier specified could not
 be resolved into a connect descriptor using one of the naming methods
 configured. For example, if the type of connect identifier used was a
 net service name then the net service name could not be found in a
 naming method repository, or the repository could not be
 located or reached.
 *Action:
   - If you are using local naming (TNSNAMES.ORA file):
      - Make sure that "TNSNAMES" is listed as one of the values of the
        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
        (SQLNET.ORA)
      - Verify that a TNSNAMES.ORA file exists and is in the proper
        directory and is accessible.
      - Check that the net service name used as the connect identifier
        exists in the TNSNAMES.ORA file.
      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
        file.  Look for unmatched parentheses or stray characters. Errors
        in a TNSNAMES.ORA file may make it unusable.
   - If you are using directory naming:
      - Verify that "LDAP" is listed as one of the values of the
        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
        (SQLNET.ORA).
      - Verify that the LDAP directory server is up and that it is
        accessible.
      - Verify that the net service name or database name used as the
        connect identifier is configured in the directory.
      - Verify that the default context being used is correct by
        specifying a fully qualified net service name or a full LDAP DN
        as the connect identifier
   - If you are using easy connect naming:
      - Verify that "EZCONNECT" is listed as one of the values of the
        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
        (SQLNET.ORA).
      - Make sure the host, port and service name specified
        are correct.
      - Try enclosing the connect identifier in quote marks.

   See the Oracle Net Services Administrators Guide or the Oracle
   operating system specific guide for more information on naming.

You're probably using the wrong tnsnames.ora file. Create a TNS_ADMIN registry setting so that all the different versions of forms use the same one.

TNS_ADMIN may also be defined as a system-wide or global variable
within the operating system. To do so:

1. Logon as Administrator.
2. Click Start > Settings > Control Panel
3. Double click the SYSTEM icon
4. From System Properties, select Environment tab.

The Environment tab lists System environment variables defined by
Windows NT - these are the same no matter which user is logged on
to the computer. When logged as as a member of the Administrator
group, you can modify, add or delete values.

5. Highlight OS in the list of Systems Variables

In the Variable field you should see: OS and in the Value field,
the value: Windows_NT

6. Change the Variable from OS to TNS_ADMIN.
7. Change the Value from Windows_NT to the complete path were the
configuration files will reside.

For example: c:\orant\net80\admin

8. Click Set, then apply.

In the System Variable table you should now see the TNS_ADMIN
variable with the path to the location of Oracle Net configuration
files.

9. Click OK to close window."


THIS IS SO GREATE...............
THIS WORKED FOR ME..............
