ORA-12154: Help Pls

Hi, all,
Under red hat linux 6.2, I have a OCI program running as mail delivery program for qmail, which is invoked by qmail-local when new mail is coming. This program runs fine in shell ( for testing ), but always gets ORA-12154 error ( could not resolve service name ? ) during login process when it is invoked by qmail.
Since it can be run in shell, I suppose the configuration of net service is correct. However, what is the difference between those two situation? Has it anything to do with security?
Any help would be appreciated.

Sorry, forget to say that I am using Oracle release 8.1.6 client for linux

Error message ORA-12154, pls help

Have got 2 database( A and B) on the same machine, A is the main database while B is meant to be the recovery catalog database, I have been able to create the catalog tablespace, but when I want to register the database from the target database from the RMAN command line with connect [b]catalog "rman_user/rman_user@B", its gives an error message of ORA-12154---TNS : could not resolve the connect identifier specified. I using windows environment, thanks in advance

Did you create a TNS alias for B database ? If not, you can use Net Configuration Assistant, in the Oracle menu, for that.
If you did already create B TNS alias, then try "tnsping B" : if result is OK, then try connecting to B DB from Sql*Plus :
C:\> sqlplus rman_user/rman_user@B

My friend, I believe you created a mess by Installing Oracle 10g Enterprise with your DHCP enable in Windows.
There are only 2 options if you want to install Oracle 10g Enterprise on Windows.
1. You install it using Static IP or not connected to network
2. You install Microsoft Loopback, it is a virtual Network driver and this should be assigned as your primary Network driver instead of your current Network.
So if you don't want any headache, the easiest way is uninstall your Oracle 10g, disable the DHCP and use static instead, then install again. that will work for sure.
Don't try to play with the listener and everything because you will get into deeper and deeper problem that end up into frustration :(
cheers

Hi...Please help...Getting ORA 12154 TNS Listener could not resolve...

Hi,
I have just loaded Oracle 10g Rel 2 in Win 2003 Enterprise Edition.
But when I try to connect to sqlplus, I am getting ORA -12154 : TNS: Listener could not resolve the connect identified specified.
I have registered the database, the listener and tnsnames have been set correctly.
I have also set the Oracle Home environment variable.
Still getting the error.
Any help will be highly appreciated.
Thanks,

I agree
ORA-12145: (does not exist in the standard manuals)
ORA-12154: TNS:could not resolve the connect identifier specified
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
ORA-12541: TNS:no listener
It is pretty easy to fat-finger these 4 message numbers. As a result, when a person has the actual and complete error message and an error number for a different message, it is usually not a bad idea to use the actual message. (Based on transposing only 3 digits compared to typing over 50 characters correctly.)
In this case the OP has really bollixed things: Subject implies a true 12154, text in the thread is an actual 12514 but mentions 12154.
As a result, there are several potentially correct answers, depending on the interpretation of the question.
- sb92075 gave the correct answer based on the number
- I gave the correct answer based on the message in the thread
- Anurag and Ed gave the correct answer based on 'the question is not formed correctly'

PLEASE HELP! Installation error :ORA-12154 - TNS

Hi everyone,
When I'm installing 9ilite and when it comes to the mobile server repository screen, it get an error message :"ORA-12154 - TNS: could not resolve service name".
But my service name pass the test of TNSPING.
Please help me and any suggestion is greatly apprieciated.
Thank you very much!

Check your tnsnames.ora and make sure that webtogo.world tns entry is correct. The entry should refer to the
correct database service name.

Ora 12154 error help needed

Hi,
I am a newbie in oracle forms. I have installed oracle database 10gr2 on windows xp in c directory. In D drive i have installed oracle developer suite 10g. When i try to connect database from developer suite i receive ORA 12154 error.
Do i need to change tnsnames.ora in developer suites 'D' directory or in database'C' directory.
Please explain me in steps so that i can configure developer suite.
Thank You

Forms will use its own Tnsnames.ora file so create alias for it
Run NetCA from
START > PROGRAMS > ORACLE - Oracle HOME name > Configuration and Migration tools > Net Configuration Assistant
and create Alias for Local naming
also make sure the Listener and Database is up and running

Gives ORA-12154 error, when trying to connect as sysdba

Hi Gurus,
I am new to oracle. I have successfully install Oracle Database 10gR2 on RHEL4.
Everyghing is working fine.
I found that loging through sqlplus not success as sysdba.(ORA-12154) But as a normal user I can loging through sqlplus. Anyway I can loging as sysdba through emctl console.
Can anyone help on this pls. Urgent.......................

You're welcome.
I dont know how this happened Probably your old password had some special characters within it, that's why I wanted to know if connecting without password did work. Then I would have advised you to change your password (avoiding special characters...).

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?

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

A question about CREATE PUBLIC DATABASE LINK and ORA-12154 error

Dear all,
I have a problem about public database link creation and I would appreciate if you could kindly give me a hand. I have the following connection parameters in my
tnsnames.ora file:
DGPAPROD.WORLD =
     (DESCRIPTION =
       (ADDRESS_LIST =
        (ADDRESS = (COMMUNITY=tcp.world)
          (PROTOCOL=TCP)(HOST=ORASR001)(PORT=1521)
       (CONNECT_DATA = (SID = DGPAPROD))
...Having the above mentioned parameters I can connect to this remote database directly in a SQL*Plus shell:
$ sqlplus username/[email protected] works pretty well and the connection is established without any problem.
Now, what I would like to do is to create a public database link to this remote database in order to avoid the user/connection switching for viewing the
content of this database. I proceeded according to the syntax indicated in the Oracle online documentation:
http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_5005.htm#SQLRF01205
Therefore I run the following in order to create a public database link
CREATE PUBLIC DATABASE LINK SR001_dblink CONNECT TO user IDENTIFIED BY password USING 'DGPAPROD.WORLD';Apparently there is no error and the link is created successfully. However it cannot resolve the remote host and whenever I run the following query
(myenterprise is the name of a table in that remote database)
SELECT *
FROM myenterprise@SR001_dblink
ERROR at line 1:
ORA-12154: TNS:could not resolve the connect identifier specifiedWhat causes this problem?
Thanks in advance,
Kind Regards,
Dariyoosh

You must have defined DGPAPROD.WORLD in tnsnames.oar on server where you DB is runnig.Hello there,
Thanks a lot for this nice solution. In fact I had to add the connection parameters into the tnsnames.ora file of the server on which the link was created (not the tnsnames.ora of my oracle client stored on the localhost)
After a bit googling I found another solution that allows to create the database link:
CREATE PUBLIC DATABASE LINK SR001_dblink CONNECT TO user IDENTIFIED BY password USING '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (COMMUNITY=tcp.world)
(PROTOCOL=TCP)(HOST=ip_adresse)(PORT=1521)))(CONNECT_DATA = (SID = GPAPROD)))';Thanks a lot for your help!

Php3 + oracle + apache - ORA-12154

Hi,
I build php3 with oracle support, installed oracle 8.1.5 on
RedHat 6.0 and used dbassit and netasst to configure it.
Oracle works fine. I can use sqlplus and read table from Acces.
But, when I try to log on oracle with php3, it does not work :
ORA-12154
here what i try to run :
<?php
print "<HTML><PRE>";
$db = "WWWITT";
$c1 = ocilogon("scott","tiger",$db);
?>
here my tnsnames.ora :
WWWITT.ITTRALEE.IE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = apache)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = WWWITT)
here my sqlnet.ora:
TRACE_UNIQUE_CLIENT = on
NAMES.DEFAULT_DOMAIN = ittralee.ie
TRACE_LEVEL_CLIENT = USER
TRACE_LEVEL_SERVER = USER
SQLNET.EXPIRE_TIME = 0
here my listener.ora :
LISTENER =

so what did i did wrong ?

Hi,
You may require ODBC access to your Oracle database; this can be
provided by Openlink Software at http://www.openlinksw.com. We
have many clients using PHP scripts on Linux/Unix to connect
with Oracle running on remote servers (or the same machine).
Good luck!

Windows 2003 R2 installation failing with ORA-12154

Windows 2003 R2 Enterprise default installation, no Windows Updates at all
Pentium 4, 2 gb ram, 127 gb hard drive
In a workgroup using DHCP
Installed Microsoft Loopback Adapter as per installation docs (which I read)
Default installation of Oracle 10g R2 Enterprise, which installs a starter database.
During the step Creating and starting Oracle instance with Clone database creation in progress at 46%, an error dialog appears:
ORA-12154: TNS:could not resolve the connect identifier specified.
The same problem occured when using a static IP address. About a year ago I followed the same steps with 2003 Enterprise (not the R2 version) and was successful. I also tried installing on XP Pro Service Pack 2 and failed at the same point.
At this point I am completely unable to install Oracle 10g R2 on Windows using the default options. I even tried just installing Oracle without the starter database and then use DBCA to create a database. It failed to create a database.

some more information
I’ve just restarted the server with its full quota of 16GB of RAM and selected both boot.ini switches (/PAE and /3GB) at server startup. I then amended the dbblock_lru_latches parameter from 128 to 64. Before I even started the database I tried running ‘ipconfig /all’ at the command prompt with the following result:
D:\Oracle>ipconfig /all
Windows IP Configuration
An internal error occurred: Insufficient system resources exist to complete the requested service.
Please contact Microsoft Product Support Services for further help.
is it windows causing these issues?

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.

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.
Thanks

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"
option --user (-u) with value comext
option --password (-p) with value noftnc
option --dblink (-d) with value test
option --stmt (-s) with value select table_name from all_tables
OCIServerAttach( test -- 4 )
FAILED: OCIServerAttach(), RC = -1
Error [ OCI error 12154 ]- ORA-12154: TNS:could not resolve the connect identifier specified
