ORA-12154: TNS:could not resolve the connect identifier specified [10g XE]
Greetings
There are many topics on this issue over the internet but None of them addresses this issue properly, so I couldn't find a solution to the problem.
I installed: Oracle Database 10g Express Edition
After the installation was done, I opened SQL Command Line
and I used the command "connect" to login
I enter the username
Then I entered the password
After a couple of seconds I got the following ERROR message:
ORA-12154: TNS:could not resolve the connect identifier specified
Screenshot of the error:
http://i35.tinypic.com/14o26g7.png
I installed this version of Oracle on both Windows XP 32 bit and Windows 7 32 bit and I get the same error message when it tries to connect.
Why doesn't Oracle work right after the installation?
Are there any further steps that need to be done in order to make this work? If so I would really appreciate any step by step help, I've been stuck trying to find a solution for days.

I wento to CMD, then I entered sqlplus / as sysdba and that just opened the SQL*Plus program in CMD (SQL>)
But nevertheless I still need to login with a user name and password which and I tried and I got the same error message.
>
We're making progress, you'll be logging in soon....
Get into SQL*Plus with the command I gave you, now type this:
alter user <theusernameyouwant> identified by abc123;followed by (still in SQL*Plus):
connectafter you type "connect", SQL*Plus will ask you for a user name and password. Use the same user name and password you used in the alter command.

Hi All,
I'm trying to run RDT on BO 4.0 using the following command on <INSTALLDIR>\SAP BusinessObjects Enterprise XI 4.0\win64_x64:
reposcan.exe -dbdriver oracledatabasesubsystem -connect "UID=ceprod;PWD=ceprod;DSN=dsnname;HOSTNAME=ip of db server;PORT=1521" -dbkey [[XXXXXXX]] -inputfrsdir "\\share\FileStore\FileStore\Input" -outputfrsdir "\\Share\FileStore\FileStore\Output"
I cannot be able to run the RDT as I get the following error:Business Objects Enterprise CMS:Unable to connect to the CMS system database DSN:dbserver ip:1521.Reason ORA 12154.TNS could not resolve the connect identifier specified
I have created DSN for oracle db using 32 bit and 64 bit ODBC drivers. I can connect from this system to the database using the client tools.
Also this is a clustered cms and do I need to use any other parameters here?
regards,
SridharHi,
Check if you have two different oracle directories listed in system variable path.
e.g.:
D:\oracle\product\11.2.0\client_1\bin;C:\Program Files\oracle\product\11.2.0\client_1\bin
If this is the case, you have two different tnsnames.ora files.
Then sometimes the first one is used and sometimes the second.
If they don't contain the same info, you get these issues.
Delete one of the paths in the system variable or synchronize the tnsname.ora files to get rid of that.
Regards

ORA-12154: TNS:could not resolve the connect identifier specified Oracle 11
I'm having a slight issue with Oracle 11 R2
Oracle 10g was removed from the machine - The registry was cleared and I couldn't see anything of 10g left.
I then installed Oracle 11 with just the software only, and then created a listener.
Using the Database Configuration Assistant, I tried to add a database but I get the error:
'ORA-12154: TNS:could not resolve the connect identifier specified'
The TNS_ADMIN is set to: \\ravel\tnsnames and I can connect to other instances around the company.

Hi guys,
I tried to execute a package with Oracle Data Source from Integration Services Catalogs and I got the following error.
ORA-12154: TNS:could not resolve the connect identifier specified
The package runs fine from the SSIS project but once I deploy to SSIS Catalog it fails to run. I need help!
Thanks
meHello ,
The ORA-12154 is a very common error, always related to your local copy of the tnsnames.ora file, your listener configuration and your database name aliases.
Make sure that your listener is listening for the same service name that you are using.
Your service name might have an alias, so check for global (world) entries and local entries. Check:
$ORACLE_HOME/network/admin/tnsnames.ora
Check your global_name setting with this SQL:
select * from global_name;

Toad ORA-12154: TNS:could not resolve the connect identifier specified
I'm installing oracle clients and tools on a new Windows 7 machine issued to me by my company.
I installed a 64 bit 10.2.0.3 oracle client, but found that 64 bit installations don't work with TOAD. So I installed a 32 bit 10.2.0.1 oracle client. I also set up my TNS names files in the network/admin directory of both installations, set up the hosts files, and ensured that the registry information is accurate. I have no ORACLE_HOME environment variable because when I installed the 2nd installation of Oracle it said that I shouldn't have one since I have multiple versions of oracle and it erased it.
I am able to connect and use SQL Plus and SQL Developer with both installations of Oracle, but I'm not able to connect with TOAD. TOAD finds the 32 bit installation and all of its registry information looks correct and TOAD says "The Oracle home is valid". TOAD also loads my TNS file and all associated IPs and everything looks good when I look at them in the the TNS Editor. I am also running TOAD as administrator in order to avoid "Can't initialize OCI. Error -1" errors.
Yet, whenever I try to connect to any database, I get the following error:
"ORA-12154: TNS:could not resolve the connect identifier specified" and then the database I am using
Is there anything else I need to setup because I have multiple installations of Oracle? Or anything else I need to setup running on a 64 bit windows machine with 32 bit installations of oracle and toad?
Thanks for any help you can give.And in case you want to know my registry information:

ORA-12154: TNS:could not resolve the connect identifier specified (sqlplus)
Hi All,
I don't know if this has ever been posted, but since I've spent a week figuring it out (no joke, a week), I thought I would post it so that no one else has to waste this much time.
"ORA-12154: TNS:could not resolve the connect identifier specified" from what I've seen on this site is a major problem for a lot of people, but I did not find a reference to my specfic problem.
FYI--
My Database is called "ordidm"
userID: SYSMAN
password: p@ssw0rd
My specific issue was the following:
I can....
- Connect to the database via the client "admin assstant" GUI in Windows while supplying the userID and password using the "Database Authentication".
- Connect via sqlplus as "/as sysdba"
- "tnsping oraidm" passes works just fine.
I CANNOT....
- connect to oraidm at the dos prompt by using sqlplus, regardless of whether or not I supply all the user authentiocation information and db name on one line, or...if I just type "sqlplus" at the command prompt and then enter the userID and password when prompted. Every time I get the "ORA-12154: TNS:could not resolve the connect identifier specified" error message.
Ready for this?? (some may have guessed this already) The problem is the "@" in my password. After looking closely at the trace logs, I noticed that one of the entries was...
[09-MAR-2009 08:23:12:921] nnftrne: Original name: ssw0rd
Remember that the format for connecting on one line at the dos prompt is
C:/> sqlplus SYSMAN/p@ssw0rd oraidm
or you can do the following...

SQL>
(BTW-I just started using the "scott" ID because from what I understand, changing the SYSMAN userID password is kind of a pain. Figured just using "scott" ID would be easier to test)
So of course what it's doing is counting everything after the first "@" as the database name...which of course it can't find in the tnsnames.ora file. Also, contrary to some other posts I found here and there, enclosing the userID and/or passowrd in quotes does not do any good. Apparently, even when using the 2nd method...in the background, the end result is it must pass the whole thing as one long string much like in the 1st method (as you will get the same truncated "Original Name" of "ssw0rd" in the log)
So...the question is, why does Oracle even allow "@" in the password if it will become an issue with sqlplus??? Also, if you can't (or shouldn't) use it, why isn't it documented somewhere? At the least I would expect the installer to at least warn you ahead of time that an "@" is not suggested. I don't remember it being there. Maybe it's just me and I'm just missing this info somewhere
I sincerely hope this saves someone else a week of their life. ;-)

My Database is called "ordidm"
userID: SYSMAN
password: p@ssw0rdThere are restrictions from oracle side how should password look:
Passwords can be from 1 to 30 characters.
The first character in an Oracle password must be a letter.
Only letters, numbers, and the symbols “#”, “_” and “$” are acceptable in a password.
And password must not be a reserved word (look into v$reserved_words).
And as You can see sysman password containt "@" - this is not allowed.

Here can be used a small trick
sqlplus sysman/"p@ssw0rd"@oraid

alter user scott identidified by p@ssword
You will get error message (ORA-00922: missing or invalid option), but You can
alter user scott identified by "p@ssword" - and that will work.
These double quotes will allow to overide Oracle restrictions. -

Please let me know why I am getting this error if everything is fine above.
Regards,
MichelHere's your issue
(HOST=localhost.localdomain)
If you are going to use "localhost" at least fake it by adding an entry in your /etc/hosts files
Example ( add to both servers so they can see each other )
192.168.0.20 primary.localdomain primary
192.168.0.21 standby.localdomain standby
Does the "hostname" return localhost.localdomain? Setup something so RMAN has something to connect to.
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address> <fully-qualified-machine-name> <machine-name>
localhost.localdomain is 127.0.0.1, you don't want that.
Best Regards

Ora-12541 ORA-12154: TNS:could not resolve the connect identifier specified
I am having trouble obtaining an ODBC connection from a client XE to a server XE. ora-12541 ORA-12154: TNS:could not resolve the connect identifier specified
I am new to Oracle.
I have oracle client XE running on my XP pro box.
I have oracle server XE running on an XP pro box on the LAN.
I am trying to connect to the oracle database using ODBC from my client box.
I can logon to the oracle server box through HTTP.
I can logon to the oracle server box by using a connection string in "Command Line SQL" from my client computer. I can then run queries on my client computer. (select * from global_name)
I cannot setup an ODBC connection in windows which will connect to the oracle server box from my client box. (I have no trouble connecting to MSSQL databases).
I can ping my server by hostname or ip address. Both ok.
I can run tnsping XE on the server box and it works. I believe this tells me my server listener is working.
I cannot run tnsping on my client box as it is not included in the download for Client XE.
Windows firewall is turned off on both machines.
I have been reading all over the web for and all attempts fail. Most all help says use Oracle Net Manager or some such tool. They then say go to start\programs\oracle….etc. There is no type program included on the server or the client software. I would like to know here I can download it.
XEClint\Bin is the firs entry in my PATH. The tnsnames.ora, sqlnet.ora, and listner.ora files are there. I have been to http://www.oracle.com/technology/software/products/database/xe/files/install.102/b25143/toc.htm several times. My tnsnames.ora are identical to the ones in the example except for the host =.
I have 3 tnsnames.ora files on my computer:
Directory of c:\
04/03/2008 11:43 AM 635 tnsnames.ORA
Directory of c:\Documents and Settings\All Users\Application Data\Microsoft\Net
work
04/03/2008 11:43 AM 635 tnsnames.ORA
1 File(s) 635 bytes
Directory of c:\XEClient\bin
04/03/2008 11:43 AM 635 tnsnames.ORA
1 File(s) 635 bytes
They are all identical.
When I ran lsnrctl status on the server the results were the same as found in other articles in the web site. Default service XE
I have the Oracle in XE Client driver in my windows ODBC driver list of the client box. And other Oracle drivers.
It appears I am lost.
Any help would be appreciated.
RandyI cannot setup an ODBC connection in windows which will connect to the oracle server
box from my client box. (I have no trouble connecting to MSSQL databases).How you tryed to do that?
On which step you have problems? -

Error ORA-12154 TNS: Could not resolve the connect identifier specified
Hi. I'm getting the above error message as I'm trying to create a connection to my oracle 10g database from visual studio 2008. (it's not an ASP.NET app, but a windows forms)
I've installed the Oracle Developer Tools for Visual Studio and am following the instructions found in the "2 Day + .NET Developer’s Guide" for connecting to the database via the "Add Data Source" menu option.
When I get to the form where I'm supposed to supply the data source name, and sign in credentials, it's failing with the above error.
I know I'm using the right credentials but I can sign into SQL Developer using the same ID and password.
Does this have anything to do with my SQLNET.ORA file? I read in another forum that you have to use SQLNET to connect to 10g databases...
is this correct?
any help would be appreciated.
Edited by: user10902634 on Jul 2, 2009 11:32 AM
I've also followed the instructions at http://download-west.oracle.com/docs/cd/A91202_01/901_doc/network.901/a90154/gettings.htm#483215. I just modified the existing service name, and tested it using the same credentials i'm using in vstudio and it worked with no problems.I found a resolution. I followed the "Oracle developer tools for visual studio FAQ". After my administrator installed the developer tools for me, i had to copy the original tns file over to the new ora home directory.
that fixed the problem.
I'm still having problems though getting my application to run on my client machines.
as a test, i started a new vstudio 2008 project. (.net 2.0) I created a new data source, connected to my oracle database using odp, and then created a data grid control that has all my data from the database.
i compile with no problems. when i copy the files to my client machine and try to run it, i get the following error:
