Hi,

I'm trying to install Oracle DB 10g on MS Windows XP Pro, on a machine having a static IP, and every time the installer stops in the "creating and starting oracle instance" step, showing the following error:
" ORA- 12154: TNS: could not resolve the connect identifier specified "

I tried the same installation on Windows Server 2003 on the same machine and got the same error.

Also I successfully installed from the same package on another machine.

need help please.

Thank you in advance,
Karim.

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.

Regards
Michel

Dear Michel,

Thank you very much for your help, but the problem is I'm totally new to Oracle administration world, and this is the testing machine I'm trying to install the Oracle software on.

and I can not figure out which type of naming should be used by default, as I did not make to pass the installation process.

Thank you,
Karim.

It is tnsnames.ora.
You don't need network part if you are testing locally.

You have to read documentation if you want to waork with Oracle: http://download.oracle.com/docs/cd/B19306_01/nav/portal_1.htm

Michel
