TNS:protocol adapter error in oracle 9i

hi,
I am using Windows vista in my PC. I just installed Oracle 9i. When I put in my
user-name and password to run SQL+ 9.0.1 it gives me the following error
message : ERROR:ORA-12560: TNS:protocol adapter error.
Please give me the steps how to fix this error.
Thanks,
Noble

Hi
You are right pal. I just tested it and it seems like when the oracle_sid is not set then you get this error.
LSNRCTL> stop

ORA-12560: TNS:protocol adapter error in Oracle Forms...

Hi, I installed Oracle developer suite to use for Oracle forms but am getting "ORA-12560: TNS:protocol adapter error" when trying to run a form. The database is running locally on my PC.
I've run the command line to see if hostname matches up with the "HOST= " in the ".../network/admin/listener.ora " file match, they do. What can I try next? I did have Oracle 10gXE installed, which I have now removed. I'm including my tnsnames and listener file content:
# tnsnames.ora Network Configuration File: C:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora

Thanks in advance for any help!

Of course you found another one. Each .and every Oracle database client home (such as developer, app server) has one.
Don't just change the port - the tnsnames.ora in the dev home does not point to a database service. It only points to an extproc [external procedure called by a database]. You need to put a database service entry into that file similar to the one in the database home. (Easiest solution - copy the tnsnames.ora from db home ... after you've made a backup)
And please don't tell me you are using Developer 6i - a simple Google search would verify that the networking is incompatible.

TNS-12560: TNS:protocol adapter error on Oracle Enterprise Linux

hi,
I am getting -
TNS-12560: TNS:protocol adapter error when I try to connect the Db installed on Oracle Enterprise Linux from other machines.
I made all the .bash_profile changes and created one shared listener also to check whether there is any problem with the dedicated default listener or its port.
Please suggest the solution .

You need to open the firewall on OEL.
Edit the contents of /etc/sysconfig/iptables file. I added the line in bold:
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter

COMMIT
As you can see, my listener port is 1521.
Do not put that line after the line with REJECT keyword ( it won't work then) !
Save and close the file. Restart iptables:
/etc/init.d/iptables restart
Now you can connect from the outside.
It works on my OEL version 5 update 4.

Does anyone have any ideas what else I can check. I'm a Unix person, not a Windows person, which is making it even more complicated. If I was on Unix, I'd just blow everything away and start again from scratch, but since I'm not sure how to remove all traces from the registry, etc., I don't want to try that on this machine. There was already one other database created, but it's not goign to be used.
Any help would be greatly appreciated.
regards,
Tarisa.

hi,
thanks for the info. the problem, as it turns out, was that I was connected to the db server via a terminal service (Microsoft Management Console), which for some reason caused probelms with TNS. After I connected directly to the machine using VNC, I was able to create the database with no problems. strange but true.
regards,
Tarisa.

If you have backup and you dropped database then you can create it again.
1) Create directories for background,user,audit dumpdest and control,online log,datafiles.
2) Create OracleServiceComp if that is not exists using ORADIM utility(oradim -new -sid COMP -intpwd <syspass> -pfile <pfile location>)
3) After starting oracle service
set ORACLE_SID=COMP
rman target /
/*if you do not have spfile also then you have to restore it from
full/auto backup or startup database using pfile(create it manually)*/
startup nomount ;
restore controlfile from 'full or autobackup location';
alter database mount;
catalog start with 'backup location';
restore database;
recover database;
alter database open resetlogs;

how can im going to login Oracle 9i database Sql Plus ? anywany other fix this problem ?
Edited by: shajib on Mar 12, 2010 1:31 PM

Step 1 - from a command line on the database machine, enter 'lsnrctl status' and report the output
Step 2 - display the contents of the %ORACLE_HOME%\network\admin\tnsnames.ora file on the machine running sqlplus.
These are the first two stepo, whether on the database machine or in a traditional client-server configuration.

Gives ORA-12560: TNS: protocol adapter error when installing oracle 10g

I tried to install oracle 10g r2 in server 2008. but it gives ORA-12560: TNS: protocol adapter error when installing. how I can fix this issue??? please help me ASAP. because its urgent.
thanks in advance.
chamara

Welcome to the forums !
Pl indicate which version of 10g you are installing and on which version of Win 2008. Neither 10gR1 nor 10gR2 are certified to be installed on Win 2008 R1, AFAIK.
For 10gR2, only 10.2.0.5 is certified for Win 2008 R2 - see MOS Doc 1173433.1 (How to Install Oracle 10.2.0.5 on MS Windows 7 / Windows 2008R2)
Also see MOS Doc 740926.1 (Where can I find the Database / Client software to download for Microsoft Vista, or Windows 2008R1?).
Both 10gR1 and 10gR2 are now in extended support - is there a reason you are not using 11gR2 ?

Vbscript to connect to oracle fails with ORA-12560: TNS:protocol adapter error

I am running a Windows 7, 64 bit system with the Oracle 32 bit client installed. The 32 bit client is required for use with Oracle's Documaker Studio which is working fine with the current client configuration. I would like to connect the same database using a vbscript. Here is the test script I am using:
Option Explicit
Dim strCon
strCon = "Driver={Oracle in OraClient11g_home1_32bit}; " & _
         "CONNECTSTRING=(DESCRIPTION=" & _
         "(ADDRESS=(PROTOCOL=TCP)" & _
         "(HOST={VSTODEEDATxx.xxxxxxx.com})(PORT=1521))" & _
         "(CONNECT_DATA=(SERVICE_NAME=IDMAKER))); uid=xxxxxx;pwd=xxxxxxxx;"
Dim oCon: Set oCon = WScript.CreateObject("ADODB.Connection")
Dim oRs: Set oRs = WScript.CreateObject("ADODB.Recordset")
oCon.Open strCon
Set oRs = oCon.Execute("SELECT TO_CHAR(SYSDATE,'MM-DD-YYYY HH24:MI:SS') AS DateTime FROM DUA")
While Not oRs.EOF
    WSCript.Echo oRs.Fields(0).Value
    oRs.MoveNext
Wend
oCon.Close
Set oRs = Nothing
Set oCon = Nothing
In the connection string I am using the 32 bit driver used succesfully by Documaker. I provided all the parms to eliminate the need for tnsnames.ora. However, I do have tnsnames.ora on my system and Documaker is using it.
Since the client is 32 bit, I am using the following command to run the script:
c:\windows\syswow64\cscript.exe c:\temp\oracle\testing\testconnect.vbs
This is suppose to run the script in 32 bit mode and be compatible with the client.
When I run the program I get the following error:
Microsoft (R) Windows Script Host Version 5.8
Copyright (C) Microsoft Corporation. All rights reserved.
c:\temp\oracle\testing\testconnect.vbs(12, 1) Microsoft OLE DB Provider for ODBC
Drivers: [Oracle][ODBC][Ora]ORA-12560: TNS:protocol adapter error
Would someone please advise on how to debug this problem? Thanks, Gary

"connectstring" is not a valid attribute with Oracle's ODBC driver, so since there is no datasource attribute specified, the app is trying to connect to a local database, and since you don't have one, you get 12560.
To resolve the problem, pass DBQ=      instead of CONNECTSTRING=

ORA-12560: TNS:protocol adapter error while configuring ORACLE Workflow

Hi,
I am trying to configure ORACLE Workflow. I have given sys password and other parameters in the given format in Workflow Configuration Assistant. My DB Server is in my local network and I connect to it using SID in SQL Plus. But I got the following error while WorlflowCA tries to execute relevant script.
ERROR:
ORA-12560: TNS:protocol adapter error
SP2-0640: Not connected
WorkflowCA: Non-Oracle10g database detected
If anybody is having any clues, please help me.
Thanks in advance
Ajish M.

Thanks a lot for your quick reply.
I've read all the posts mentioned (quite a few more) but I couldn't find any suggested solution to the "non-oracle10g"-problem other than using the global db name instead of the sid - which didn't help in our case:
However, in a last desperate attempt to solve the problem on my own before launching another cry-for-help-post I did try running the configuration assistant using the correct password for the SYS user 8-} and - strange but true - it did work :-)
Needless to say: I used the global db name of course, so I can't say what would have happened without it, but I trust your hint was a legitimate one.
Anyway - I gues that error Message concerning a "non-oracle10g database" was slightly misleading in this case.... grrrr.

It is also possible to get that message is you are not using the same adapter (or do not have networking) when the listener attempts to start or when trying to connect.
Post the results of
ipconfig /all
lsnrctl status
and the contents of the listener.ora and tnsnames.ora found in the %ORACLE_HOME%\network\admin directory
And tell us what steps you skipped/missed in the install doc at http://www.oracle.com/pls/xe102/homepage

TNS:protocol adapter error while starting Listener created by Oracle SES11.1.2.2 Setup

I am trying to install Oracle Secure Enterprise Search 11.1.2.2 on Windows 7 64-Bit Enterprise Edition.
The machine has Oracle Client installed on it. Loopback adapter was configured.
The setup created a Listener named LISTENER and SID is ASUSES.
I am getting the following error when trying to start the Listener.
LSNRCTL> start LISTENER
TNS-01106: Listener using listener name LISTENER has already been started
LSNRCTL> status

Kindly let me know what should be done.

i have done that. i copied the tnsnames.ora, sqlnet.ora, listener.ora files from the c:>oracle-home\network\admin folder into oracle_devhome\network\admin folder. i have also set the environment variable oracle_sid=skoolman. skoolman is my sid as you can see on the tnsnames.ora. but the error massage still comes up as soon as i run forms from the forms builder environment.
but as i said i am able to connect to the database with my user name and pass word from within the forms builder environment to access my tables and create data blocks etc but as soon as i run the form through internet explorer the forms servlet boots up and the error massage ora-12560 tns protocol adapter error pops up.
thanks guys for your heip. please i need more solutions

Hello,
Probably that you already have the listener up and running from your installation of SES.
Also, you could check in your Windows Services (from the Control Panel), you'll see that
there is a service like OraclesesTNSListener up and running.
If it is the case, then it's probably why it is telling you the message below when trying to start it again:
TNS-01106: Listener using listener name LISTENER has already been started
Then, before trying to start the listener, you can check if it is already up by running the command : lsnrctl status
If you need to shut it down, then you can run the command : lsnrctl stop
for example, from the command line:
> set ORACLE_SID=ASUSES
> set ORACLE_BASE=D:\ses\
> set ORACLE_HOME=D:\ses\seshome
> cd %ORACLE_HOME%/bin
> lsnrctl status            <== this will give you the status of your listener
> lsnrctl stop              <== this will stop your listener
> lsnrctl start             <== this will start your listener
Hope this can help you and others.
Regards,
-Stephan

Oracle 64bit Server (From JD Edwards) and oracle 32 bit client showing ORA:12560 "TNS: protocol adapter error "??

I installed 64bit Oracle successfully and was able to connect to DB using SQL Developer and sqlplus (Oracle E1local and TNSListener is up and running). I installed Oracle 32bit client and copied both tnsnames.ora and sqlnet.ora files to C:\app\Administrator\product\11.2.0\client\Network\admin. But if i am trying to access DB through Oracle 32bit client (thru cmd as sqlplus /sys as sysdba or thru sqlplus , it is throwing ORA:12560. "TNS: protocol adapter error ". (Both 62bit server and 32 client on same VM machine - Windows 2008 R2 ). I directly executed sqlplus from "C:\app\Adm\....client\bin", but it is still throwing same error and because of this JDEdward installation is not able to find if any database is running or not.!
My environment variables order: %PATH% = C:\app\Administrator\product\11.2.0\client\bin;c:\Oracle\E1Local\bin; I have seen all the previous threads and try setting ORACLE_HOME and PATH variable using CMD and tried accessing the database, but it fails all the time.
Please help me with the problem. Thanks in advance.

Thread moved from Peoplesoft forum to JD Edwards.
