Connect to Oracle through ODBC - TNS: No Listener Error

Hi All,
I've been trying to chase this problem down for over a month now and I have had no luck. When I try to connect to an Oracle server through MS Access I get the TNS: No Listener error. The kicker is when I go to the odbc data source administrator in windows I am able to connect to the oracle server. My computer is windows 2007 and I have Oracle 11.2 installed. Could anyone assist?
When I type lsnrctl start in the command prompt it says it has been already started.
Here is my tnsnames.ora:
ORMANRPT.WORLD=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=bspz1565.bhdc.att.com)
(PORT=1521)
(CONNECT_DATA=
(SID=ORMANRPT)
Here is my sqlnet.ora:
AUTOMATIC_IPC = OFF
TRACE_LEVEL_CLIENT = OFF
names.directory_path = (TNSNAMES)
names.default_domain = world
name.default_zone = world
names.default_domain=world
here is my listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = C:\app\cb260e\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:C:\app\cb260e\product\11.2.0\dbhome_1\bin\oraclr11.dll")
LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ADR_BASE_LISTENER = C:\app\cb260e

I suggest you move, remove, rename, delete or otherwise move the listener.ora file out of the way.
listener.ora is NOT required to start or utilize the listener
open Command Window after doing as directed above then issue the OS commands below
lsnrctl stop
lsnrctl start
lsnrctl status
# now wait 60+ seconds before issuing the next command below
lsnrctl service
COPY the results from all above, then PASTE all results back here.

Cannot connect to Oracle through ODBC.

Please help, I don't know what else to try.
I'm writing automated test scripts and frequently need to access the database to verify data values. These scripts run under multiple environments and have to validate several different flavors of database products. I use ODBC to establish the database connection and this works well under everything except the following environment:
Database Host:
Windows Server 2008, Standard Edition
Oracle 10g
Client:
Windows Server 2008 Standard (64-bit)
Oracle 11g client software installed.
Following recommendations here on the Oracle site, I used the OUI to remove the Oracle ODBC driver that is installed with the client software and installed RDBODBC3320_x64.msi.
I was unable to connect to the database at all using the Oracle 10g client software under this environment, but it is my understanding that Oracle 11g should work. I don't have much choice. The Oracle 10g client refused to install in this environment.
I am able to create a DSN for the database using the ODBC Data Source Administrator. I specify the configuration correctly, but when I try to test the connection, it returns the error:
FAILED: Service Connection test
rc=-1
SQLState=08S01
[Oracle][ODBC][Rdb] Connect Ret -1 Err# 10061
WSAECONNREFUSED Connection refused
I interpret this to mean that I'm reaching the server and database, but it isn't recognizing the connection as being from a legitimate account. Am I wrong?
From this client machine, I am able to connect to and query the database using SQLPlus, so it isn't that the database is unavailable from the test machine.
On the host server, I am able to create an ODBC configuration that tests successfully. That is, of course, the 10g version of the ODBC driver.
I hope someone can supply an answer, this is a high visibility item that is making me look foolish.
Thanks,
Dave P.

Hi Dave,
It's difficult to make decent recommendations without knowing for sure even what kind of database you're connecting to, or what issues you're having exactly. "No success with the 64 bit flavor" doesn't provide much info to go on.
Here's the bullet points that will hopefully get you working, assuming you're connecting to "regular" oracle and that this whole RDB thing was a wild goose chase. If you're actually connecting to an RDB database, skip all the steps below and go post in the RDB forum to get their advice. If you're not sure what the difference is, or what you're connecting to, ask someone who knows.
*1)* Are you ultimately trying to connect with a 32 bit app or a 64 bit app, from the 64 bit 2008 box?
- What kind of "scripts" are you writing? VBSscript you're executing from a DOS prompt? If so, how are you invoking it exactly? Just by typing filename.vbs?
- Are the scripts running with 32bit cscript.exe or 64 bit cscript.exe?
The bottom line is that 32 bit apps need 32 bit client software, and 64 bit apps need 64 bit client software, and you need to have the right stuff installed. The first thing you need to figure out is whether you're running 32 bit app or 64 bit process. Usually you can open Task Manager and look for the process name in the Process tab; if there's a *32 next to it, it's 32 bit. Otherwise it's 64 bit.
*2)* Once you determine what bitness the software you're running is, you then need to download and install that bitness of Oracle client software. You can get 11.2.0.1 here:
32 bit 11.2 client:
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win32soft-098987.html
64 bit 11.2 client:
http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win64soft-094461.html
*3)* After downloading the client.zip and extracting it, run setup.exe, take the defaults, chose Custom install type, select ODBC driver and SQLPlus from the list, and the installer will automatically install the Oracle software as well.
Note: You could use Instant Client for this as well; but you'll have to download and install SQLPlus and the ODBC driver in addition to the instant client itself, and using the OUI and the Full client installation is "easier" as it doesn't require manual installation like Instant client does, so less error prone.
*4)* Configure tnsnames.ora for that install so the client knows where you want to connect to, test it using sqlplus from that install location to make sure you have it right.
*5)* If you want to configure a 32 bit dsn, you need to use the 32 bit administrator ( c:\windows\syswow64\odbcad32.exe).
64 bit dsn's you configure via c:\windows\system32\odbcad32.exe (or via control panel > odbc administrator).
*6)* Run your app, hopefully you're dialed.
*7)* Profit.
Hope it helps,
Greg

Oracle XE installation (TNS:protocl adapter error)

Hi,
I have been reading through all emails regarding installing Oracle 10g XE.
I have successfully installed XE on Windows XP on first attempt with no problems.
Next, I have to install on Windows 2000 but during the Installation process Task 1 of 5 ends prematurely.

3. value of TNS_ADMIN env variable.
I did not have it set as this machine never had Oracle before and I am newbie to Oracle. I will set it a try again. I'll also define TNS_NAME as I just learned about this one too.
now my Env variables have:
COMPUTERNAME=MYPC
ORACLE_BIN=c:\oraexe\app\oracle\product\10.2.0\server\bin

======================
Now I have stopped and re-started the services in this order.

These last two don't automatically start w/ Beta 3 but I started anyway.
A quick check to see if:

No luck. Which I expected because I think the XE database needs to be created first. So let's check to see if I can get into sqlplus now.

TNS:no listener error with dblink

I am able to connect to oracle database 10g machine from other machine with oracle 8i then I have create dblink in 8i machine but when I am accessing 10G database it is giving me error
for example select count(*) from t_cons@orcl
ORA-12541: TNS:no listener
is it a version issue or something else?

Thanks Dushyant.
following is the result of query
SQL> select value from v$parameter where name='global_names';

one thing I have noticed that when I am connecting to database server with same
hostname & dbname then there is no problem but when hostname & dbname is
different then it is not connecting through dblink.
I have gone through oracle doc but no where it is mentioned that both should be same.

Thanks for reply.I checked with onsite DBA for listener and it is up.If you have an on-site DBA why aren't you working with him to solve the problem?
Since you assert that other client machines are able to connect to the database, the issue must be with your own setup. I strongly suspect your tnsnames has a bad entry. Please compare it to the same file from a working client. Also, show us the contents of your tnsnames.ora file.

"TNS:no listener" error

Hi,
I have got Oracle 9iR2 on Redhat 8 I have installed Oracle 9i client software on Windows 2000.
Using the Oracle Net Configuration Assistant I am trying to set up my connection to my Linux server. When I com to test the connection I get
CONNECTING ORA-12541: TNS:no listener
The listner is started on the linux box so I am a bit stuck at the moment
I would be very greatful if someone who has set up a linux server/windows client before could let me know what they did or if anyone knows of any documentation that would be a good starting point
many thanks

Check the SID you configured in the client with <oracle_home>\network\admin\tnsnames.ora.

TNS-12541 TNS: No Listener error HELP!!!

Hello,
We have installed Oracle 8.0.5 on Windows 2000.
Oracle was well installed (no errors) but sometimes we can connect to the database (via SQL+ or by a tnsping on the client), sometimes we cannot and it shows above message (TNS-12541 TNS: No Listener). That is very strange: the listener do really exist and is running. (Service is started). I tried to stop and start manually the listener (tnslnr80) but the 'start' failed (it was too long so I killed the command).
Can someone help us to solve this or to understand what happens?
Thx a lot

SQL*Plus: Release 11.2.0.3.0 Production on Tue May 7 17:29:56 2013
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Enter password:
ERROR:
ORA-12560: TNS:protocol adapter error
C:\Users\mohammed>
Could you please advise..
Regards,
MohammedIf the client is on the same machine as the database, then you don't have ORACLE_SID set.
More likely the database is on a different server, you have to specify 'sqlplus sys/pswd@dbname'.
And your db will need to be configured to allow remote sysdba authorization, which is not a good idea from a security perspective.

TNS no listener error when internet is enabled

Hi
When my internet connection is enabled and if i try to connect to the database, I get the No listener error.
Although I'm able to connect to database when there is no internet I find it hard to run my forms 9i as they run on Internet Explorer and only when there is internet connection.
Please help me in this regard.
Thanks in advance
rishank

I think, that your listener listen to only one address.
Try to edit tnsnames.ora to replace you hostname with local network address.
