Suddenly unable to connect Reports to database: ORA 12154 TNS can't resolve

Beginning end of last week, the Reports development tool (rwbuilder v10.1.2.0.2) suddenly lost the ability to connect to the database. The error is ORA-12154: TNS: could not resolve the connect identifer specified.
However, nothing has changed on either the database or my workstation. SQL*Developer and the Network Administrator can both access the database, confirming the configuration of TNSNAMES.
A fresh install of the DevSuite (rwbuilder v9 something) onto another workstation yielded the same error. The problem seems to be with Reports, not my workstation, my TNSNAMES configuration, or the database itself.
What could possibly cause the database to reject only Reports?

Well, continued searching this forum revealed the answer. It was found in:
ORA - 12154 - Unable to resolve TNS..
It seems that something did, indeed, change on my workstation. I renamed all of the TNSNAMES.ORA files other than the one used by the network administrator. It seems that Oracle*Reports requires its own copy of the TNSNAMES file. What I don't understand is how it gets updated when changes are made to the real TNSNAMES file via the network administrator.
In any event, I'm back up and running. Sorry for the wasted bandwidth.

Here'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.

Error Could not connect to the database - ora-12545: tns:name lookup failure

Hi,
I am a tech at a failing company. Unfortuneatly some users still need ADI installed and working with very limited resources to troubleshoot oracle. I am getting the error - ( Could not connect to the database - ora-12545: tns:name lookup failure )when the user tries to log on to ADI. Any suggestions? I would really appreciate it. We are on Windows NT on an NT network. Oracle 8.05 client installed and ADI 6.0.
Thanks, Mary

Connect to Remote Database - ORA-12154

Am I doing this in the correct location, or am I missing something else in the process for remote databases.
I have no trouble connecting to a local database with a empty string in the OCIServerAttach call.
Thanks in anticipation.

ORA-12154: "Could not resolve service name"
ORA-12541: "No listener"
ORA-12154: "Could not resolve service name"
When you try to connect to your database through Developer, try using the connect_string you've been using with .world added to it (sometimes it's appended to your connect_string automatically, and if your sqlnet.ora file has NAMES.DEFAULT_DOMAIN and NAME.DEFAULT_ZONE set to anything other than 'world' then you may have to create a new sqlnet.ora file and set NAMES.DEFAULT_DOMAIN and NAME.DEFAULT_ZONE to world for it to work properly.
ORA-12541: "No listener"
You just need to verify that the listener is running and also is listening for the SID or CONNECT_DATA value being sent be PL/SQL Developer. For example, if the listener on your remote machine is listening for 'pl_sql' but when you try to connect to the remote database the PL/SQL Developer is sending a request to connect to 'plsql', then there is 'no listener' listening for 'plsql' and it fails. IF you can connect to the remote database via sqlplus, but then when you try it from PL/SQL Developer and it fails, that means the listener is in fact running, but not listening for the correct string being sent to it by the application.
Hope this helps.

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.

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

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 :-

Any ideas ?

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.

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 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?

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

I can tnsping my machine using another machine:

1). I have TNS entries under MW_HOME/OracleBI/network/admin
2). TNSPING works fine.
3). JDBC source set up on WLS side..
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?

the conection works fine on our old XP OS....
any idea what i have to do to get this to run on Windows 7

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 connect identifier specified

Hi,
I have Oracle 11g (Release 1_32bit) Client on my C:\ drive which connect to a Remote 11g (11.1.0.7.0 - 64bit) server.
I have installed 10g DB Server(10.2.0.1.0) and Oracle 10g Forms(Forms [32 Bit] Version 10.1.2.0.2 ) on my D:\ drive.
When I try to connect to Oracle 10g DB from Forms using "Connect" button, I get following error:
"ORA-12154: TNS: could not resolve the connect identifier specified"
Tns and Listner files both are same in Developer_Suite home and 10g home.
Can someone please help me with this error?
Thanks

"ORA-12154: TNS: could not resolve the connect identifier specified"
$ oerr ora 12154
12154, 00000, "TNS:could not resolve the connect identifier specified"
// *Cause: A connection to a database or other service was requested using
// a connect identifier, and the connect identifier specified could not
// be resolved into a connect descriptor using one of the naming methods
// configured. For example, if the type of connect identifier used was a
// net service name then the net service name could not be found in a
// naming method repository, or the repository could not be
// located or reached.
// *Action:
//   - If you are using local naming (TNSNAMES.ORA file):
//      - Make sure that "TNSNAMES" is listed as one of the values of the
//        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA)
//      - Verify that a TNSNAMES.ORA file exists and is in the proper
//        directory and is accessible.
//      - Check that the net service name used as the connect identifier
//        exists in the TNSNAMES.ORA file.
//      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
//        file. Look for unmatched parentheses or stray characters. Errors
//        in a TNSNAMES.ORA file may make it unusable.
//   - If you are using directory naming:
//      - Verify that "LDAP" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Verify that the LDAP directory server is up and that it is
//        accessible.
//      - Verify that the net service name or database name used as the
//        connect identifier is configured in the directory.
//      - Verify that the default context being used is correct by
//        specifying a fully qualified net service name or a full LDAP DN
//        as the connect identifier
//   - If you are using easy connect naming:
//      - Verify that "EZCONNECT" is listed as one of the values of the
//        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
//        (SQLNET.ORA).
//      - Make sure the host, port and service name specified
//        are correct.
//      - Try enclosing the connect identifier in quote marks.
//   See the Oracle Net Services Administrators Guide or the Oracle
//   operating system specific guide for more information on naming.
$
Tns and Listner files both are same in Developer_Suite home and 10g home.Listener files are totally useless in Developer Suite home, since they are server files.
