When using a dblink, the database with the link is acting as a client to the remote database ... exactly like sqlplus running on the db server.

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.
My tnsnames entry is:
GMAN_1120.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = gman)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = ora112)
If i start the listener i get:

Can anyone spot what may have gone wrong? I've setup 10g multiple times and never had a problem

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?

BO 4.0 Repository diagnostic tool-ora 12154.TNS could not resolve the connect identifier specified

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,
Sridhar

Hi,
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
Moritz

what else do I need to do?

Show the full exception stack trace. This doesn't seem to relate to WebLogic. Does the WebLogic console
show the DataSource as running? Are you in fact using the WebLogic DataSource?

Hi,
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.

ORA-12154: TNS:could not resolve the connect identifier specified Error in Integration Service Catalogs

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
me

Hello ,
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:

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

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.

08004:[oracle][odbc][ora]ora-12154: TNS: could not resolve the connect ....

This error has just recently started happening, and i cannot figure out why, i have not changed anything in tnsnames.ora file.
i am always able to "test connection" in ODBC. even when i get the error in crystal.
so i restart Crystal, and i am able to connect to db.
strange thing is that always when i do a tnsping to db i always get the message :-
TNS-12541: TNS:no listener
Any ideas ?

I am receiving a similar error.
Failed to open the connection.
Details: 08004:[Oracle][ODBC][Ora]ORA-12154: TNS:could not resolve the connect identifier specified [Database Vendor Code: 12154]
I've seen all sorts of discussion on the intertubes about possible fixes however, none stated are practical or they do not address my error specifically. I've exhausted resources on the net as well as those available to me.
I'm currently running SAP Crystal Reports 2011 on WIN7 64bit and using Oracle in OraClient 10g_home1.
Please let me know what insight you have. I cannot roll back to previous versions of Windows nor less encryption.
Thank you for your time.

ORA-12154: TNS:could not resolve the connect identifier specified using TOAD client

I try to using connect with remote database using TOAD client. My oracle version is 10.2g. I follow these instructions that specified on this link, instead of step 13, because i cant understand what they explain http://http://avangari.wordpress.com/remote-oracle-database-access-using-instant-client-and-toad/ . My Oracle TNS_ADMIN path is C:\oracle\product\10.2.0\db_1\network\ADMIN and ORACLE_HOME is C:\oracle\product\10.2.0\db_1. I found many question regarding this query, but i am not found my answer.

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.

C:/> sqlplus SYSMAN/p@ssw0rd oraidAnd here You can see why this symbol is restricted as full syntax for sqlplus in this case will be:
sqlplus username/password@oraidm
but in Your case @symbol already is in password.
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.
