ORA-12154 after 10g Developer installed

Guys
Not seen any specific references to these exact circumstances, and this may be in the wrong forum, but please bear with me .....
I've recently installed Oracle Developer Suite 10.1.2.0.2 on to my PC. Now, every time I try to connect to any Oracle database via PL/SQL Developer, Impromptu/Cognos etc, I get;
ORA-12154: TNS:could not resolve the connect identifier specified
Everything worked fine before the Developer install. As far as I can see my PC has exactly the same files and settings as before, as my old PC that was dumped a couple of weeks ago and as colleague's PCs who have not installed Oracle 10g Developer and are happily accessing databases.
Is there something the install amends that may have impacted?? Something that I need to be aware of or accomodate??
Thanks in advance for any help
Ian

You are about the 100000000 person with this problem.
This problem occurs when not reading the installation manual, not trying to find out what is going on, and jumping to the Usenet or this forum rightaway to ask this boring question AGAIN.
Why do people never pay attention? Why can't they be bothered to read the troubleshooting section in the Net administrators manual?
Why does everyone need to be spoon fed.
The answer is for the 100000001 time:
You have installed Developer in a different Oracle_home, you now have TWO different tnsnames.ora, and you need either
- to synchronize them
or
- to set TNS_ADMIN string variable in HKLM\software\oracle to the old tnsnames.ora directory.
Can't anyone sue Bill Gates for causing a worldwide epidemia of laziness?

Ora-12154 after creation of second database

DB 10g ver 10.1.0.2.0
OS Windows server 2003 32bit +sp1
Summary:
Due to the addition of extra storage to the server I decided to rebuild from scratch, and all was working correctly until I came to create a second database on the server, once this is created I get ORA-12154 errors at logon for both databases.
Full:
Installation of Windows and Oracle are fine, creation of the first database also works correctly and connection is without problems e.g sqlplus user/pass@database1 allows me to logon.
On creation of the second database the same command: sqlplus user/pass@database1 or sqlplus user/pass@database2 gives me an ORA-12154 error.
If in the command prompt window I set ORACLE_SID=database1 then try sqlplus user/pass it connects without problems, the same for database2, although sqlplus user/pass@database1 still fails.
I have checked tnsnames.ora, all looks fine, I used the net configuration assistant to generate the entries and used the connection test to verfiy all was ok, both connection tests worked fine.
I can tnsping both database1 and database2 and lsnrctl status shows
Service "database1" has 1 instance(s).
Instance "database1", status READY, has 1 handler(s) for this service...
Service "database1XDB" has 1 instance(s).
Instance "database1", status READY, has 1 handler(s) for this service...
Service "database2" has 1 instance(s).
Instance "database2", status READY, has 1 handler(s) for this service...
Service "database2XDB" has 1 instance(s).
Instance "database2", status READY, has 1 handler(s) for this service...
I have searched through back posts and the web and as yet have not been able to find how to resolve this. Any pointers or ideas as to why I cannot use the sqlplus user/pass@database to connect?
TIA

Hi,
Thanks for the quick reply, I created the listener using the net configuration assistant, I assumed this would add all necessary configuration entries?
I have added an extra section as suggested to the listener.ora, it now reads
# listener.ora Network Configuration File: c:\oracle\product\10.1.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

 (ORACLE_HOME = c:\oracle\product\10.1.0\db_1)
 (SID_NAME = medline)

)Is this correct, I have bounced the listener and still get ora-12154 errors on connection.

ORA-12154 after a few hours

My application runs fine for a few hours, before returning an "ORA-12154: TNS:could not resolve service name" error when trying to open an ADO connection to an Oracle 9i database.
1) What does this mean? It can't find the name server, it can't find a matching name in the name server, it can't find the machine the name refers to, or it can't find the requested database on the machine? Or something else?
2) What could be the cause? Since it works perfectly for some time before giving an error, I assume everything is set up correctly. Are there options other than a glitch in the network? Is it possible for the application itself to be doing something that triggers the TNS error?
3) What can be done about it? If it's a temporary problem reaching the name server, is it possible to somehow cache the results, so that if the name server isn't found, it will default to the previous definition of the name?

I'm not entirely surprised nobody has a solution to my problem, but surely somebody can at least explain what the error message means? Does it mean that no definition for the name is found at all, or could it occur if the definition points to a machine that is no longer accessible? If connection to the name server is lost, will Oracle look in the local tnsnames.ora instead of reporting that failure to connect?

Is Oracle Client 10 part of Oracle 10g Developer Suite install?

Hello,
I am currently using Oracle Client 9i for Business Objects. I suppose once I move to Oracle 10g Developer Suite, I'll need to move this to Oracle 10g Client. Is this a separate install from the developer suite?
Thanks.

A Developer install should be including it's own Oracle Client -- ie Oracle_Home. That is how I've seen it in older versions -- haven't done Developer installs for quite a few years now !
See http://download.oracle.com/docs/cd/B25016_08//doc/dl/core/B16012_04/chap2.htm#i1018939 and http://download.oracle.com/docs/cd/B25016_08//doc/dl/core/B16012_04/chap3.htm .
The 10g Developer install is expected to be seperate from existing ORACLE_HOMEs

Loosing connections with ORA-12154

Our scenario goes like this. We run transaction(1000's) fine for a while
(hours!), then we get the following errors in sequence for short period of
time(~2-5 minutes):
<JDBC Pool> Sleeping in createResource()
<JDBC Pool> Sleeping in createResource()
<JDBC Pool> Connection for pool "bankframePool" created.
<JDBC Pool> Connection for pool "bankframePool" created.
<JDBC Pool> Sleeping in createResource()
<JDBC Pool> Sleeping in createResource()
Our application, during that time, stops with ORA-12154 from Oracle. Then
everything seems to recover fine and we process transaction again fine for
hours. Why would we loose the connections like this while we are running
transaction non stop through the system?
Regards,
Andre Dionne

We are running on solaris 8. This morning we tried to start the application
servers with the minimum connection equal to the maximum(150) and we got
ORA-12154 after creating 122 connections. Could it be related to the Oracle
OCI8 driver we are using?

Andre DionneHi. For stability and performance, I recommend defining your connectionpool
to make all it's connections at startup (init = max). Oracle is sometimesweak
when being asked for lots of connections at any one time. Sometimes itgets overrun,
and fails some connection attempts. Also, tell me if you're running onSolaris.

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.

ORA-12154 Error After Install of Enterprise Manager

I have a new new laptop with minimal software installed. Everything was fine and I was able to connect to 4 different Oracle 9i databases.
This morning I installed Oracle Enterprise Manager (10g) and now I get the dreaded ORA-12154 error.
I now find a copy of TNSNAMES.ORA in three places. I have copied the correct version to the two new 10G locations and I have verified that all three copies of TNSNAMES.ORA and SQLNET.ORA are correct and identical.
Do anybody have any idea what else could be wrong?

I am certain the TNSNAMES.ORA file is fine as it is "pushed" from a central IT department. I have compared it to the one on a second computer (which has only 9i installed) in my office and they are identical.
I examined the Oracle 9i directories and there was no LISTENER.ORA anywhere. On the 9i only computer the command - C:\>dir listener.ora /s /p executed in a DOS window returned no files.
Everything was working fine until I installed Enterprise Manager 10g (10.2.0.2.1).
I have TOAD installed and it connects to both of the 9i development and production databases, so I know the TNSNAMES.ORA is okay.
It woudl seem that there is a conflict between 10g and 9i Developer/2000.

Oracle 10G 2 install on RedHat Enterprise Linux 4 - Get ORA-12154 exception

During the install, on the step "Oracle Database configuration assistant", I am getting the error:
ORA-12154 TNS": could not resolve the connect identifier specified.
Has anyone seen this before? I am struggling for past couple of days on this.

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: 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 Developer 6

I need advice on resolving ORA-12154 while trying to
connect to a database using developer 6 ( Win NT 4.0
install using SP5 - standalone machine ).
I've installed :
Oracle 8i ( home - OraHome81 ) - :\Oracle\Ora81
Oracle Client ( home - OraClient ) - :\Oracle\Ora81Client
Oracle OEM ( home - OraOEM ) - :\Oracle\OraOEM
When I installed developer it needed to be installed
as :\Oracle\Oradev
I have a starter database and have configured it with
Net 8 easy config, the connection test ran O.K.
However when trying to connect to the database from
developer I received an ORA-12154.
I've checked technet.oracle.com and looked at document id
'106355.243 WIN:ORA-12154 and SQL*NETV2' for any advice.
The TNS listner and the database have been started in the
Oracle services.
The TNSNAMES.ORA file exists but I'm not sure of the
correct location.
Help please !

<body>
hope this will help, i had this same problem and looked up the site with for
a solution, got some good 
tips, but nothing seemed to work............well there are two solutions, stated
below 
 
first my system and its configuration, 
i'am using oracle 9i enterprise installer and developer suite 6i, on windows nt
OS with the following 
hdd's...... 
c drive fat, 55mb, OS loader drive (for future multi-boots OS's ) 
d drive, ntfs, 16gb, contains the OS and programs etc 
e drive, ntfs, 8gb, dedicated to hold oracle db 
the original installation: the e drive held all data and code for the oracle
database server and 
developer suite 
in other words, the e drive contained both the homes, the database and developer
homes (under e:\oracle) 
the d drive held all installation requirements and logs 
under d:\program files\oracle 
 
first soln, least head-breaking, requires a definite amount of time, not more
then usual, not less then 
usual 
clean restart, 
removed all the oracle services installed into nt ( namely used a freeware prog
called Service+ ) 
delete everything under HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE key 
using regedit ( be very careful what u do in regedit, there is no recovery here
) 
and cleared all files under e:\oracle dir ( need a reboot to remove all files,
some wont delete coz they 
are still active and loaded ) 
also cleared everything under d:\program files\oracle so that the next new
installation doesn't know of the 
previous one 
after doing that, rebooted, and re-installed the database server - 9i enterprise
and then installed the 
typical forms developer 6i suite ( no forms server as of yet) 
after doing all this, the db's client (sqlplus) was able to connect to the
server, but the forms client 
(another sqlplus, under the developer home) wasn't able to connect. 
to solve that, went to E:\oracle\ora90\network\ADMIN 
( i.e. [ORACLE_HOME]\network\ADMIN ) and copied listener.ora, sqlnet.ora and
tnsnames.ora into 
E:\oracle\ora90\dev6i\NET80\ADMIN ( i.e. [DEVELOPER_HOME]\net80\ADMIN ) 
and all problems were solved 
 
the other method, could b faster, but also could take forever, depend on ur
'luck', but definitely more 
head breaking, is to replace the '.ora' files with the info provided below, 
here are what my files contain at the moments ( and yes all works fine with em ) 
1. LISTENER.ORA 
# LISTENER.ORA Network Configuration File: E:\oracle\ora90\network\admin\listener.ora 
# Generated by Oracle configuration tools. 
 
LISTENER = 
(DESCRIPTION_LIST = 
(DESCRIPTION = 
(ADDRESS_LIST = 
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0)) 
) 
(ADDRESS_LIST = 
(ADDRESS = (PROTOCOL = TCP)(HOST = driven)(PORT = 1521)) 
) 
) 
) 
 
SID_LIST_LISTENER = 
(SID_LIST = 
(SID_DESC = 
(SID_NAME = PLSExtProc) 
(ORACLE_HOME = E:\oracle\ora90) 
(PROGRAM = extproc) 
) 
(SID_DESC = 
(GLOBAL_DBNAME = drvn) 
(ORACLE_HOME = E:\oracle\ora90) 
(SID_NAME = drvn) 
) 
) 
 
2. SQLNET.ORA 
# SQLNET.ORA Network Configuration File: E:\oracle\ora90\network\admin\sqlnet.ora 
# Generated by Oracle configuration tools. 
 
SQLNET.AUTHENTICATION_SERVICES= (NTS) 
 
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME) 
 
3. TNSNAMES.ORA 
# TNSNAMES.ORA Network Configuration File: E:\oracle\ora90\network\admin\tnsnames.ora 
# Generated by Oracle configuration tools. 
 
DRVN = 
(DESCRIPTION = 
(ADDRESS_LIST = 
(ADDRESS = (PROTOCOL = TCP)(HOST = driven)(PORT = 1521)) 
) 
(CONNECT_DATA = 
(SERVICE_NAME = drvn) 
) 
) 
 
INST1_HTTP = 
(DESCRIPTION = 
(ADDRESS_LIST = 
(ADDRESS = (PROTOCOL = TCP)(HOST = driven)(PORT = 1521)) 
) 
(CONNECT_DATA = 
(SERVER = SHARED) 
(SERVICE_NAME = MODOSE) 
(PRESENTATION = http://HRService) 
) 
) 
 
EXTPROC_CONNECTION_DATA = 
(DESCRIPTION = 
(ADDRESS_LIST = 
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0)) 
) 
(CONNECT_DATA = 
(SID = PLSExtProc) 
(PRESENTATION = RO) 
) 
) 
 
that's the end of it, 
in the text above, where it says ....... 
>> HOST = driven , replace 'driven' with ur computers name, b4
reinstalling i had tried 127.0.0.1, but it 
didn't work, so just stick to the computer name ( to find ur computer name look
under "Control Panel > 
SYSTEM" properties ) 
>> ORACLE_HOME = E:\oracle\ora90 , replace 'E:\oracle\ora90' with
the folder that u have chosen 
on ur computer while installing the database server 
>> GLOBAL_DBNAME = drvn , replace 'drvn' with the name of the db that u
have created 
>> SID_NAME = drvn , replace 'drvn' with the SID that u stated while
installing the db server, if u 
havent modified the default, it will be the same as GLOBAL_DBNAME 
>> SERVICE_NAME = drvn , replace 'drvn' with the service that u have
started, this can b located under 
"Admin Tools > Services" look for a service begining with "OracleService" on my
computer it is 
"OracleServiceDRVN" where DRVN in the service name, to confirm the service name,
look at the services 
properities, it will something like "Path to executable:- e:\oracle\ora90\bin\ORACLE.EXE
DRVN" where 
'DRVN' was the service name 
if u used all defaults while installing, SERVICE_NAME, SID_NAME and
GLOBAL_DBNAME will all b the same 
 
just modify the files as stated above and place them in 
[ORACLE_HOME]\network\ADMIN and [DEVELOPER_HOME]\net80\ADMIN 
 
hope that helps 
-df 
 
p.s.: to make sure have replaced all the instances, give a search for the 
following keywords one at a time 
1. driven 
2. drvn 
3. E:\oracle\ora90 
if the lookup fails, good, everything is in place and it should(will) work.

Please check the configurations which i made as well may be i am wrong somewhere.....
For further info i am pasting my configuration files.
Gateway Home C:\OraHome_1\network\admin\listener.ora
LISTENER =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=zahid)(PORT=1522))
(ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=tg4msql)
(ORACLE_HOME=C:\OraHome_1)
(PROGRAM=tg4msql)
Rest everything is commented
Oracle Database home C:\oracle\product\10.1.0\Db_1\NETWORK\ADMIN\listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = zahid)(PORT = 1521))
C:\oracle\product\10.1.0\Db_1\NETWORK\ADMIN\tnsnames.ora
tg4msql=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=TCP) (HOST=zahid) (PORT=1522) )
(CONNECT_DATA=
(SID=tg4msql))
(HS=OK))

ORA-12154 means that the Oracle database cannot resolve the tnsnames entry 'tg4msql'. Just make sure that your oracle database has the following entry in the $ORACLE_HOME/network/admin/tnsnames.ora entry:
tg4msql=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)(HOST=zahid)(PORT=1522)
(CONNECT_DATA=
(SID=tg4msql)
(HS=OK)
But checking your config you have...
To start with, activate an sqlnet trace on your database, add following lines to the sqlnet.ora in your C:\oracle\product\10.1.0\Db_1\NETWORK\ADMIN\ path:
TRACE_LEVEL_CLIENT=16
TRACE_FILE_CLIENT=client.trc
TRACE_FILE_DIRECTORY=C:\TEMP
and restart your SQL*Plus session and try the select again. This should generate a sqlnet client trace which hopefully will show why the database cannot resolve 'tg4msql' to the tnsnames.ora entry specified. For example are you using the TNS_ADMIN variable?

Oracle 10g installation ora 12154 i really need help anyone

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

9i Report Builder stops working after 10g install

I have the 9i Developer Suit installed and recently I installed the 10g Developer Suit. After installing the 10g Developer Suit the 9i Report Builder stopped working. When I try to start it, it hangs at the launch screen. All the other apps in the 9i and 10g Developer Suits seem to work except for the 9i Report Builder. Please Help.

Nope. The 10g report builder works fine. The issue is only with the 9i report builder.

Error while installing oracle 10g developer suite on windows xp

I am getting following error when i am trying to install the oracle 10g developer suite windows xp with sp3
+*"---------------------------*+
Oracle Universal Installer+
---------------------------+
Error in writing to directory c:\TEMP\OraInstall2010-03-18_12-57-52PM. Please ensure that this directory is writable and has atleast 55 MB of disk space. Installation cannot continue."+
Even i have enough space of my C drive plus i m the administrator on my PC. I changed the temp location as well and download the zip files(installation) again but it doesn't work. Kindly provide some solution for this error.

Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator (URL). (12202) This means you already have ISA configured as proxy server. Disable the proxy from the browser and you should be able to access the application. Or simply add the application URL to the list of the proxy exceptions.

ORA-12154 when connects. Instant client installed.

Hi. I am installed instant client 10.2 and cannot connect to database : give error ORA-12154: TNS:could not resolve the connect identifier specified. I am using Linux. I am set TNS_ADMIN and put into this directory file tnsnames.ora with all necessary instances, but have not no one result.

Add the following line to sqlnet.ora in the directory to which TNS_ADMIN points:
TRACLE_LEVEL_CLIENT = SUPPORT
Then try again and examine the *.trc file created. This should tell you what's wrong.
Yours,
Laurenz Albe
