ORA-12154: TNS:could not resolve... - sql plus works, env vars are set...
Hi,
I am getting this error message in my ASP.Net apps (namespace Oracle.DataAccess.Client) and any app that tries to use the Oracle Provider for OLE DB.
Error:
ORA-12154: TNS:could not resolve the connect identifier specified
Here is what I do know:
- My ORACLE_HOME is set to C:\oracle\product\11.1.0\client_1\
- My path has C:\oracle\product\11.1.0\client_1\network\admin;C:\oracle\product\11.1.0\client_1\bin;
- I installed Oracle Client 11g, previously 10g was working but one of the devs wanted to upgrade
- I can connect using sqlplus user/pass@tnsname
- I can test tns entries successfully in Net Manager
Here is what I don't know:
- When using OLE connections, why does Oracle Provider for OLE DB not pick up on the environment variables - sql plus seems to, that's why it works.
- In ASP.Net, why does the connection object from Oracle.DataAccess.Client not pick up the correct environment variables?
- How do the Oracle drivers pick up the location of the TNS names?
Thanks,
Michael

Hi,
What "environment variables" are you referring to that you have set? You shouldnt have to set any, unless you're talking about TNS_ADMIN just to avoid having to configure multiple TNSNames.ora's if you have multiple homes.
Your PATH doesnt need to include OH\network\admin, but thats not hurting anything. PATH is for dll loading, not for finding config files.
Do you still have 10g installed? When you connect using sqlplus user/pass@tnsname, are you using 11g sqlplus? Or is that coming from the 10g client? Multiple homes arent aware of each other, so if you have a 10g home and an 11g home, you'd have to configure tnsnames.ora for both (or use tns_admin).
As far as I know, the client software picks up tnsnames.ora by checking:
1) the local working directory
2) the tns_admin directory
3) the network\admin directory of the client home being used.
Hope it helps,
Greg

Discoverer Plus Error: ORA-12154:TNS:could not resolve the
Hi,
I’m running the Discoverer report in Discoverer Plus and getting the below error, but when the same report ran in Desktop completes successfully and the SQL from the report is running without error in SQL nav.
Database Error - ORA-12154:TNS:could not resolve the connect identifier specified.
Thanks in Advance.
SunilHi Sunil,
Did you test the direct method I posted above? That will bypass the tnsnames.ora file. If it connects fine that way, then you likely have a configuration issue with your sqlnet.ora and/or tnsnames.ora
You can test with:
$ORACLE_HOME/bin/tnsping <tnsalias>
If it is successful, then check if you have the TNS_ADMIN environment variable set (echo $TNS_ADMIN) -- assuming Linix/Unix, if Windows, check system environment variables
You may TNS_ADMIN set and pointing to a tnsnames.ora that is not in the default location.
If it fails and your tns entry is correct in the tnsnames.ora file, then you may need to look at the sqlnet.ora
For example,
If you have NAMES.DEFAULT_DOMAIN set.. then you would need enter: <tnsalias>.<domain> (i.e. scott.world)
or you may need to check if TNSNAMES is first in NAMES.DIRECTORY_PATH=
You can remove or rename the sqlnet.ora to make sure that is not an issue.
Hope that helps. Good Luck.

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.

ORA-12154 TNS could not resolve service name error
Hi
I'm having trouble connecting to database throug sql*plus.I'm able to connect through TOAD but getting 'ORA-12154 TNS could not resolve service name error' when trying to login through sql*plus using same credentials .
I tried running sqlplus through command prompt,but when i enter the user-name i'm getting ORA-12203:TNS:unable to connect to destination.
Can someone help me with this error.
Thanks.It would probably give you an idea where to start looking. You need to make sure that you have the correct .ora files needed for establishing connections. I don't know if your service desk just does the installation but no setup or if they also do the setup configuration. You can also try doing the setup on your own to check. You can use net easy config.

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...

(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.

About ORA-12154: TNS:could not resolve service name
Hi~
i have a problem about Oracle Form/Report connecting
when i keyin UserName/PassWord & Service Name(like myInstance_172.22.22.22) connecting to Instance,connection failed(Form/Report),error as follow
ORA-12154: TNS:could not resolve service name
but when i try this(the same userName/PassWord & Service String) on the SQL*Plus or DBA(OEM),it can successfully connection to Instance.
what should i to do to resolve this problem?
Thanks.Robson
"TNS:could not resolve service name" means the tnsnames.ora file doesn't have the entry for your service name.
There are couple of situations where this error can come even if you see the sqlplus works
Please check the follwoing
1. You may be having morethan one tnsnames.ora file in your system and the entry doesn't exist in any one of them , which is unfortunatel used by Forms/Reports.
In your Oracle_Home for Forms / Reports, serach for the folder Network/admin or Net80/Admin and see the tnsnmaes.ora file there. Ensure you have the proper entry for your referred tnsname
2. If your Reports server / client is in different machines, ensure both the machne's tnsnames.ora files have the entry
Alternatively, you canedit the registry of your Oracle_Home to add another variable call ed TNS_ADMIN and give your directory where theproper tnsnames.ora
is available
Thanks

ORA-12154: TNS:could not resolve the connect identifier
I am simply trying to move a site from a Windows 2003 32bit server to a Windows 2008 R2 64-bit. The database was on and is remaining on the 2008 server. Trying to run the new site results in:
ORA-12154: TNS:could not resolve the connect identifier
This error pops up more than a few times in the forums but do not seem unique to my situation where I know the connection string works fine from another server. Any insights?Working

ORA-12154: TNS:could not resolve the connect identifier speci
Getting this Error on our new windows 7 64bit OS

I can make the conection to the db by Loging directly into the Oracle SQL using the same info as my sams.
the conection works fine on our old XP OS....
any idea what i have to do to get this to run on Windows 7
thanksHi,
1) Check the tnsnames.ora file you are using, verify that it is accessible.
Eg: On Unix:
- Check if you have a $HOME/.tnsnames.ora file - This will be
used in addition to 'tnsnames.ora'.
- Check TNS_ADMIN is set in your environment.
- There is a readable tnsnames.ora file in $TNS_ADMIN
2) Ensure that the tnsnames.ora file contains a line of the form
'alias=(...)' for the alias you are specifying.
Aliases are NOT case sensitive.
3) Make sure that there are no mismatched parentheses in the
tnsnames.ora file.
4) Even if TNS_ADMIN is set SQL*Net looks in other locations for
configuration files. Check the default directories for old (or bad)
copies of TNS_NAMES.ORA. Eg: /etc, /var/opt/oracle,
$ORACLE_HOME/network/admin
5) Check the default domain name being used, and the path used to
locate aliases, in the SQLNET.ORA file.
The default domain is specified in the NAMES.DEFAULT_DOMAIN
parameter - this is appended to the alias specified in the
connect string if there is no domain given.
Eg: If NAMES.DEFAULT_DOMAIN=mydom.uk
and a connect to "scott/tiger@mydb" is requested
SQL*Net will look for the alias "mydb.mydom.uk"
If NAMES.DIRECTORY_PATH is also specified this determines where
SQL*Net looks for the alias expansion.
6) If none of these show an error enable client side tracing
at level 16 and see what has been written to the client trace
file. There list of aliases in the trace file under the heading
'TNS.NAMES.ORA TABLE HAS THE FOLLOWING CONTENTS'.
7) If ORA-12154 is returned when selecting over a database link from a
client check that the alias in the link can be resolved in the
tnsnames.ora file ON THE SERVER.
8) If you are connecting from a login dialog box, verify that you are
not placing an "@" symbol before your connect net service name.
9) When going from Windows to Linux/Unix platforms,
you can see <carriage return> <new line> characters at the
end of each line instead of <new line> <new line>. Be sure you
use ascii mode when ftp'ing this between Windows and Linux/Unix.

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;

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?
