Hi William,

I getting fail to open connection when try to direct connect
without go through tnsnames.ora file My oracle client is 10g . Tks

Ok, if your 9i set up is using Oracle Names for resolution, then you
will have to create a 10g tnsnames.ora file because the 10g client
cannot use Oracle Names.

The quickest way to do this is to connect to the namesctl utility and
run the "dump_tnsnames " command. When done, the filename you
specify will be suitable to use as a tnsnames.ora file.

Copy it to the 10g home\network\admin folder and you should be good to
go.

If you are not using the Oracle Names system, then your 10g client needs
to have a tnsnames.ora file (and probably sqlnet.ora as well) that are
the same as the ones in the 9i client.

There are two ways to achieve this:

  • Copy the files from 9i\network\admin to 10g\network\admin; or

  • In the registry, add a TNS_ADMIN entry to the 10g Oracle Home, and
    point it at the location of the 9i\network\admin.

The first option is easiest, but you then have to make sure you make
changes in both the 9i client and the 10g client files.

The second option means that you only ever edit the 9i files and the 10g
client will pick them up as soon as you are done.

To do this:

Run regedit and navigate to HKLM/software/Oracle.

Note that there are a number of "HOMEn" entries listed on the LHS.

For each of the HOMEn entries, click it. The RHS will show you the
settings. Look for the ORACLE_HOME setting in each one and stop when you
find the location of the 10g client.

Now, in the RHS, right click and choose NEW form the context menu.

Select "STRING VALUE" from the list that appears.

Type TNS_ADMIN as the name of the string value, to replace the default
of "New Value #1". Press ENTER.

Double-click the TNS_ADMIN entry in the RHS.

In the dialogue (EDIT STRING) that appears, type in the full path to
your Oracle 9i_home\network\admin folder and click OK.

Exit from regedit.

If you now attempt to connect to a database that 9i client can find but
10g client cannot, you should be able to connect to it using 10g now.

Cheers,
Norm. [TeamT]

Hi,

Actually i have try as you mention by doing tnsnames.ora on 10g client. but i still not able to connect as per error message. I am sure that my tnsnames.ora on oracle home 10g is correct. I use normal sqlplus from my pc to the 9i database server is not problem. I am using winxp 64 bit.

ORA-12154- TNS could not resolve the connect identified specified.

Morning William,

ORA-12154- TNS could not resolve the connect identified specified.
This error means that Oracle cannot take the database alias you supply
and convert it to a host/port/sid_or_servioce where the database lives.

I suspect that your sqlnet.ora is not quite correct, possibly.

Try the following with the 10g client. (cd \bin):

tnsping

You should get the same error. Then try:

tnsping .world

You might get a result this time. If so, you need to amend the
sqlnet.ora file to add an entry:

NAMES.DEFAULT_DOMAIN=world

You may need to check that your entry in tnsnames.ora under the 10g
client is identical to the one in tnsnames.ora under the 9i client. Can
you please show me the corresponding entry form the 9i and 10g client
from the respective tnsnames.ora files? If desired, you can XXXXXX out
the host & port - for security purposes. Thanks.

Also, please post the sqlnet.ora file from both the 9i and 10g client.

Cheers,
Norm. [TeamT]
