ORA-12154 on WinXP x64

Hello,
I have a WinXP x64 with Oracle Client 9.2
it works fine with SQLplus,SQL Navigater and XAMPP server
but with Golden and Crystal I get everytime an error
"ORA-12154 could not resolve service name error"
with a normal WinXP SP2 I did not have problems
Has anyone a solution for my problem?

Did you ever find a solution? I have the same problem.
I have tried the Oracle 32 bit and 64 bit client applications. Both were installed in C:\oracle\product... when I tried them. The 32 bit client was 10.1.0.2 and the 64 bit was 10.2.0.1. Both will not allow me to use an ODBC connection in MS Access.
MS Access is part of Office 2003 and is installed in the C:\Program Files (x86) folder. I even tried installing Access from Office XP in C:\Program Files and had the same results.
I have tried creating the ODBC connection from Control Panel>Administrative Tools and from C:\Windows\SysWOW64\odbc32.exe. Both would let me connect to Oracle successfully, but when I try to use them in MS Access I get errors. For the 64 bit ODBC driver I get an error that it isn't installed, and for the 32 bit ODBC driver I get an ORA-12154 TNS names error.
HELP!

64-bit OCILogon() is fine, but 32-bit version always gives ORA-12154

Hello,
I am porting an application from Oracle 9.2 on Solaris 8 on Sparc to
Oracle 10.2 on Solaris 10 on x64, using Sun C++ 5.8 on both.
The Oracle installation was quite straightforward, and everything works fine, except that if I compile my app for 32-bit all I ever get from
OCI is 'ORA-12154: TNS:could not resolve the connect identifier specified'
sqlplus and tnsping, which are both 64-bit executables are also fine.
Here is a little example program which writes a few BLOBs into
an existing table:

Recompiling for 32-bit like this works fine on Oracle 9.2 on Solaris 8,
so I have obviously missed something simple in my installation.
Any help would be appreciated.

Hi prajithparan,
I am facing the same problem on my Dual Core AMD running Solaris 11.06 x96-64. As long as I compile and link using the flag '-m64' everything work fine. But I use '-m32' or none getting 32 bit binaries I got the same error:
'ORA-12154: TNS:could not resolve the connect identifier specified'
even my LD_LIBRARY_PATH is set as below:
echo $LD_LIBRARY_PATH
/oracle/app/product/10.2.0/lib32
Also I have to mention that SQLPLUS and TNSPING works fine on my side too. So I suppose that there is something wrong with trying to use 32 bit ORACLE libraries. Any idea?
Please find attached my output (my APP is OCI / C based but not OCCI / C++):
./cdemouni user comext password noftnc dblink test stmt "select table_name from all_tables"

ORA-12154 Error

Hi there,
I am having a problem connecting to a database that we have just created on a new server. The connection is fine using SQL*PLus, Enterprise Manager or SQL Developer, but we have an application that connects to this database sitting on the same server and this returns the error listed above. The username / pwd etc are all correct in the config file, and is a .NET app, but I cannot understand why it won't connect. I am using the standard oracle client (Oracle.Client) in .NET, the only real difference is that I am running the software on a x64 OS, could this be causing a problem?
Many thanks for any help that you might be able to provide
Dan

Hi Dan,
It sounds like the local sqlnet.ora or listener.ora file is wrong . . .
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;
The query value should match your init.ora parms for db_name and db_domain, You can change the global_name with an alter database commend, as follows:
alter database rename global_name to xxx;
ORA-12154: 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.

ORA-12154 Connection error from HFM to Oracle Database

Hi,
I am trying to configure Hyperion HFM but can write to HFM database.
The implementation architecture:
Hyperion 11.1.2.2 (with all the requiered patches for HFM, FDM, Shared Services, Workspace and Oracle Application Development)
Server 1:
Windows Server 2008 x64
Installed products: Foundation (EPMA, CalcManager), BI, HFM web components and ADM driver
Configured products: Foundation(EPMA, CalcManager), BI.
Database Client: 11gR2 x64
Server 2:
Windows Server 2008 x64
Installed products: HFM, FDQM
Configured Products: FDQM, HFM
Database Client: 11gR2 x32, 11gR2 x64 (x32 version installed first)
Server 3:
Database: Oracle 11.2.0.2
All the products from server 1 are working fine, FDQM (server 2) is also working fine, but, when I try to do any action related with HFM database the system fails.
I have tested the connection is these scenarios:
1. SQLdeveloper: successfull!, I can create tables, views, etc. Double checking the user privileges it has all the required.
2. tnsping: successfull!
3. HFMApplicationCopy utility: Successfull using UDL file and writing the connection parameters.
4. EPM System Configurator: the configurator successfully validates the database connection information, but does not create the tables on the database. No errors in the configtool log.
5. EPM Diagnostic Tool: fails with this error message:

Hi,
I Have solved one of my problems, the one that keep HFM from connecting to the Oracle database.
I just change the TNSNAMES.ORA, like this:
Initial tnsnames.ora
PRUEBA.WORLD=
+(DESCRIPTION_LIST =+
+(DESCRIPTION =+
+(LOAD_BALANACE = ON)+
+(FAILOVER = ON)+
+(ADDRESS_LIST =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = <server_name>)(PORT = <port>))+
+)+
+(CONNECT_DATA =+
+(SERVICE_NAME = <service_name>)+
+)+
+)+
+)+
Modified tnsnames.ora
PRUEBA.WORLD=
+(DESCRIPTION =+
+(LOAD_BALANACE = ON)+
+(FAILOVER = ON)+
+(ADDRESS_LIST =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = <server_name>)(PORT = <port>))+
+)+
+(CONNECT_DATA =+
+(SERVICE_NAME = <service_name>)+
+)+
+)+
I Just delete the line "+(DESCRIPTION_LIST =+" and its corresponding closing parenthesis, I did this cause in the configuration utility log I saw this line:
+TNS parsing: Entry: DESCRIPTION_LIST [[Address: Protocol:(TCP) Host:(<server_name>) Port:(1521) SID:(<service_name>)]]+
So, if the applications were trying to connect to connection descriptor DESCRIPTION_LIST, the driver could not recognize DESCRIPTION_LIST as a valid one.
There is a lot going on behind the scenes when you work with Oracle Database as the repository, maybe there is some other way to address this issue, but it worked for me, hope it can help you too.

Unable to Connect, ORA 12154, Setup routine for Microsoft ODBC errors

Hi all,
I have a Windows 7 Enterprise 64bit SP1 system and I wanted to be able to connect to an oracle database server. However, I am facing a problem with ODBC configuration.
I have currently installed both below in ... product\11.2.0\client_1 folder:
1. Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64) - http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html
2. 64-bit Oracle Data Access Components (ODAC) - http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html
I launched ODBC Data Source Administrator and added a User DSN but resulted to two errors:
1. The setup routines for the Microsoft ODBC for oracle ODBC driver could not be found. Please reintall the driver.
2. The specified DSN contains an architecture mismatch between the driver and application.
On top of that, if I go to System DSN tab, and tried to test the connection it give me an error:
1. Unable to connect SQLState = 08004 [Oracle][ODBC][Ora]ORA-12154: TNS: Could not resolved the identifier specified.
Can someone please guide me through this? Thanks in advance!

1. Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64) - http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html
2. 64-bit Oracle Data Access Components (ODAC) - http://www.oracle.com/technetwork/database/windows/downloads/index-090165.html
You only need one of these (the second one should suffice).
I launched ODBC Data Source Administrator and added a User DSN but resulted to two errors:
1. The setup routines for the Microsoft ODBC for oracle ODBC driver could not be found. Please reintall the driver."Microsoft ODBC for Oracle" is a different provider than "Oracle ODBC". Make sure you're not using the Microsoft one.
2. The specified DSN contains an architecture mismatch between the driver and application.This can happen if you're mixing 32-bit and 64-bit. There's two ODBC control panels in Windows 7:
- the 64 bit one is the one in control panel
- the 32 bit one is c:\windows\syswow64\odbcad32.exe
Since you're using a 64 bit Oracle driver, you should be using the 64 bit ODBC administrator, and 64 bit applications. If you're trying to use this ODBC connection with a 32 bit application, you'll need to use the 32 bit ODBC (and the 32 bit Oracle driver).
On top of that, if I go to System DSN tab, and tried to test the connection it give me an error:
1. Unable to connect SQLState = 08004 [Oracle][ODBC][Ora]ORA-12154: TNS: Could not resolved the identifier specified.Well that actually means it's loading Oracle correctly, so that's something. You need to add an entry for the server you want to connect to into tnsnames.ora, located in the \network\admin folder inside of your Oracle client installation. Since it sounds like someone else set up the server you want to connect to, your DBA should be able to provide the information that goes into the file.

The server could not be found on the network ORA-12154

Hi All,
I have problem with one application. She run with Oracle DB. I installed Win2008R2 x64 and Oracle DB 32bit on the same server. I tried connect to DB via Oracle SQL Developer and SQL Plus and both run without problem, but when I insert the same parameters into application OpenText Content Server 10, then I see this Error:
Content Server Error:
[Error: The server could not be found on the network. ----> Error stack ----> 1) E675414020:The server could not be found on the network.:ORA-12154: TNS:could not resolve the connect identifier specified ]
This application need only 3 parameters (System User Name, password and service name). I compare it with ORA files (listener, sqlnet and tnsnames) and I think that all is right. Here are this three files
listener:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = WIN-R0OEE0OAE5Z)(PORT = 1521))
sqlnet:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES)
tnsnames
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = WIN-R0OEE0OAE5Z)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
Do you have any idea where is problem?
Thank you
Vaclav

VaclavYou listener has nothing to do with this error. Your request for a connection never left the client machine.

ORA-12154(Urgent PLZ)

I have installed oracle app. server Rel2 on winXP professional, after installation when i try to connect through PLSQL editor it says error ORA-12154 unable to resolver service name. I have checked for tnsnames.ora file in ORA_HOME/network/admin and i cant find it. so what to do ?

Hi,
 Sorry, I'm confusing, do you install Oracle database server, or Oracle application server ?
 Perhaps the Oracle Application Server - General is more suitable in your case.

Error while trying to retrieve text for error ORA-12154

Hello,
I try to install php 5.1.2 on a WIN2003 server and IIS6 with the OCi8 extension without success from several days.
On my server I've a 920 oracle client and the 10.1 instant client, I copy the tnsnames.ora in the instant client's directory.
I've declare many environnement variables :
- NLS_LANG : AMERICAN_AMERICA.WE8MSWIN1252
- TNS_ADMIN : E:\...\oracle\instantclient_10_1
- ORA_NLS33 : E:\..\oracle\920\ocommon\nls\ADMIN\DATA
With the php command line the oci_connect function correctly works : the php command line use the instant client's tnsnames.ora. I can query with success my database.
When I try to load a web php script (the same as the php command line script) I have the following error " Error while trying to retrieve text for error ORA-12154" ( oci_connect( $user , $pass, $sid ) . The $sid variable have the value of an alias declared in the tnsnames.ora.
If I replace the sid's alias by something like this " (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=xx.xx.xx.xx)(PORT=1521)))(CONNECT_DATA=(SID=xx)" in the oci_connect function, I have another error : Error while trying to retrieve text for error ORA-12705.
A web page with the phpinfo function displays the following messages about oci8 extension : It seems to be correct.
oci8
OCI8 Support enabled
Revision $Revision: 1.269.2.8 $
Active Persistent Connections 0
Active Connections 0
Temporary Lob support enabled
Collections support enabled
Do you have any idea ? Thanks a lot

The web server is not seeing the Oracle environment correctly. You need to set PATH to the instant client libraries. ORA_NLS33 is not used for Oracle 10g clients. Perhaps you have some library conflict with two versions of Oracle on the machine?

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 when using Database Link

We're running 11r2 on our servers. I have a primary db and a standby db, using Data Guard. The standby is open for read-only querying. We are not using ASM.
The primary (and thus the standby) have a PUBLIC database link to a third db server.
When I run a query against the database link on the primary: select * from test@MyDBlink; Everything works fine.
When I run the same query against the database link on the standby: select * from test@MyDBlink; I get ORA-12154: TNS:could not resolve the connect identifier.
I check that the db link exists on the standby. It does.
I go to command prompt on the standby and run "tnsping MyDBlink". It executes fine. It says "Used TNSNAMES adapater to resolve the alias" and sure enough, MyDBlink is referenced in the TNSNAMES.ORA.
I also run "tnsping IP-of-MyDBlink" to doublecheck. No issues.
What is going on that is blocking the db link on the standby? Many reports utilize that standby and I'd hate to deny them the functionality of a db link.
Thanks

ThanksMost people with this problem don't understand that the dblink is just another client, no different than sqplus running on the same machine - and therefore the link uses the tnsames in the ORACLE_HOME of the database containing the link. But it seems from the steps you've described that you've grasped that. The only thing I can think of off the top of my head is when you try sqlplus from the standby server you are hitting a different tnsnames than the one the database is using.

Sql@loader-704 and ORA-12154: error messages when trying to load data with SQL Loader

I have a data base with two tables that is used by Apex 4.2. One table has 800,000 records . The other has 7 million records
The client recently upgraded from Apex 3.2 to Apex 4.2 . We exported/imported the data to the new location with no problems
The source of the data is an old mainframe system; I needed to make changes to the source data and then load the tables.
The first time I loaded the data i did it from a command line with SQL loader
Now when I try to load the data I get this message:
sql@loader-704 Internal error: ulconnect OCISERVERATTACH
ORA-12154: tns:could not resolve the connect identifier specified
I've searched for postings on these error message and they all seem to say that SQL Ldr can't find my TNSNAMES file.
I am able to connect and load data with SQL Developer; so SQL developer is able to find the TNSNAMES file
However SQL Developer will not let me load a file this big
I have also tried to load the file within Apex (SQL Workshop/ Utilities) but again, the file is too big.
So it seems like SQL Loader is the only option
I did find one post online that said to set an environment variable with the path to the TNSNAMES file, but that didn't work..
Not sure what else to try or where to look
thanks

Hi,
You must have more than one tnsnames file or multiple installations of oracle. What i suggest you do (as I'm sure will be mentioned in ed's link that you were already pointed at) is the following (* i assume you are on windows?)
open a command prompt
set TNS_ADMIN=PATH_TO_DIRECTOT_THAT_CONTAINS_CORRECT_TNSNAMES_FILE (i.e. something like set TNS_ADMIN=c:\oracle\network\admin)
This will tell oracle use the config files you find here and no others
then try sqlldr user/pass@db (in the same dos window)
see if that connects and let us know.
Cheers,
Harry

ORA-12154 while installing Oracle 10g on windows 7

Hi,
I am trying to install Oracle 10g express edition on my machine (core 2 duo 2.93) running on Windows 7.
The installation moves on perfectly for the 1st step and while running the 2nd step (Net configuration Assistant), it gives the ORA-12154 error.
The contents of my configuration files at this point are as follows:
Listener.ora
=============
SID_LIST_ORCL =
(SID_LIST =
(SID_DESC =
(SID_NAME = ORCL)
(ORACLE_HOME = F:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
ORCL =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
=============
And that of tnsnames.ora is:
=============
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = ORCL)
=============
After some googling around, I have found and installed the Microsoft Loopback adapter too (since my LAN is DHCP enabled) and also tried to turn on the firewall on my machine to check if it is not a problem with the port 1521 being blocked by the firewall.
However, even after all that I still get the error "ORA-12154: TNS:could not resolve the connect identifier specified." while running the Net configuration Assistant and/or running SQL Plus to connect to the SID - ORCL.
I can only see one service running in my services by the name : OracleOraDb10g_home1TNSListenerORCL
Any suggestions or advice on the error would be much welcome.
Is it anything related to Windows 7 ? Because I have managed to install using the same installer on another machine which runs Windows XP and everything seems fine there.
Thanking you all in anticipation.

Hmmm.. but then I'd have expected some installation error. I have read around that people have managed to install oracle on windows 7.
The error displayed seems to be indicating that there is some configuration or permissions issue.Check that the user has permission to write in the ORACLE_HOME\network\admin - UAC might be blocking that.
Install with software only, and run netca & dbca separately to create the database after the s/w install. (That's the way it is done in production anyway, so get used to it.)
But yes - you still may have problems. Those who did fake it out on Windows 7 usually understand what to do. If you are smart enough to actually do it, my hat is off to you.

Error while trying to retrieve text for errror ORA-12154

Hi,
I have an Oracle8 database installed and able to connect it from my Desktop running Windows 2000 Server.
I have setup my PL/SQL developer ver 6 on my laptop running Windows XP Pro SP2 and the oracle client with Net8 service setup. Able to logon via sqlplus command.
However, when i run the PL/SQL program and enter the logon info, it couldn't connect and prompt me this error.
Thanks for your help in advance.
Warmest regards,

Tony,
Can you please post the error details that you are getting while connecting from PL/SQL developer.
The error ORA-12154 is generaly TNS:could not resolve service name .
Also perfrom these steps
1)Verify that a tnsnames.ora file exists.
2)Verify that there are not multiple copies of the tnsnames.ora file.
3)In the tnsnames.ora file, verify that the net service name specified in your connect string is mapped to a connect descriptor.
4)Verify that there are no duplicate copies of the sqlnet.ora file.
5)If you are using domain names, verify that your sqlnet.ora file contains a NAMES.DEFAULT_DOMAIN parameter. If this parameter does not exist, you must specify the domain name in your connect string.
6)If you are not using domain names, and this parameter exists, delete it or disable it by commenting it out.
7)If you are connecting from a login dialog box, verify that you are not placing an "@" symbol before your connect net service name.
Hope this helps.
Thanks
