11.1.7 on Windows 2008 R2 - Error TNS:protocol adapter error

I am getting the error on Windows 2008 R2 ORA-12560: TNS: protocol adapter error.
Even I applied the patch: 9166858
Installed the software and created the Database with Database Configuration Assistant.
Even I started all the Oracle Services.
Same problem I am getting for 10.2 g also.
Edited by: sk123 on Jan 30, 2010 4:27 PM

I installed the patch
11.1.0.7.0 Patch 22 (11.1.0.7.22P) 32-Bit Patch:9166858 64-Bit (x64) Patch:9166861
It works.

ORA-12560:TNS:protocol adapter error on windows 2008 server(32 bit) for 10g

Hi Friends,
I am installaing Oracle 10g database on windows 2008 Server(32-bit) and when the Database is getting cretaed and during the database files copying portion it's throwing the error :
ORA-12560: TNS:protocol adapter error
I tried intsllaing 10g software alone and invoked DBCA and again during the database files copying portion it's throwing the same error
what could be the issue?
Regards,
DB

Pl indicate which version of "10g" and which version of Windows 2008 - R1 or R2 ?

Any suggestions for how to fix this error?

What's the status of the corresponding Windows service? OS error 1058 means normally service is deactivated. In the worst case it could be necessary to remove the service from the registry. Afterwards reboot the machine and recreate the service by 'lsnrctl start'.

ORA-12560: TNS: protocol adapter error - startup mount on windows

hi all,
I want startup the database with mount option on windows.
The OracleServiceORCL is stopped.
I need to startup mount, but I get the error:
ORA-12560: TNS: protocol adapter error.
In Linux this task is easy, but on windows I cannot connect
to database to startup mount.
How can I do this?
thank you

thank you!Once the windows service is started, you can use sqlplus to connect, shutdown, and startup just like you do in *nix.

Thx.

Yes, the XP firewall is running. During the Oracle instalation it poped up twice, but I selected 'Unblock'. I can't turn it off because it is running using the domain settings, but I can add exceptions (programs or ports). Port 1521, tnsping or sqlplus are not blocked and there is an option 'Display a notification when Windows Firewall blocks a program' witch is checked.

How to solve ORA-12560:TNS:protocol adapter error?

I'm trying to use sqlplus on Windows 2008 R2 which is installed on VirtualBox to access an Oracle 11gR2 database on Red Hat Linux.
I'm sure that the database on Red Hat Linux is up and tnsnames.ora is a copy from another machine which is used by another application to connect to the same Oracle database.
When I run sqlplus, I got the ORA-12560: TNS:protocol adapter error.
sqlnet.ora
SQLNET.AUTHENTICATION_SERVICES = (NTS)
Both sqlnet.ora and tnsnames.ora are located in c:\app\administrator\product\11.2.0\client64\network\admin folder.
The registry ORACL_HOME has c:\app\administrator\product\11.2.0\client64.
echo %ORACLE_HOME% incommand window returns %ORACLE_HOME%
echo %ORACL_SID% in command window returns %ORACLE_SID%
If I set ORACLE_HOME to another folder, I will get the following error:
Error 6 initializing SQL*Plus
SP2-0667: Message file sp1<lang>.msb not found
SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory
So, I believe the ORACLE_HOME in registry has the correct value.
I have also tried set ORACLE_SID to the service name listed in tnsnames.ora but sqlplus still returns the ORA-12560:TNS:protocol adapter error.
For unknown reason, the value of ORACLE_HOME and ORACLE_SID I set by using set command will not persist after I close the command window that I set the values.

It make NO sense do to as above when attempting to connect to Oracle DB on *NIX
which knows NOTHING about NTS Authentication.
SQLNET.AUTHENTICATION_SERVICES = (NONE)
or just remove the line or whole file.
Also need to be sure that ipchains is disabled on *NIX system

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 ?

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.

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.

TNS-12560: TNS:protocol adapter error

Hi,
I recently upgraded from oracle 9 to 10g and I get the error above.
I created a new database I CAN connect to it using sqlplus (from console), but I cannot connect using any ide.
.ora files are the following:
listener.ora:
LISTENER =
     (DESCRIPTION_LIST =
          (DESCRIPTION =
               (ADDRESS_LIST =
                    (ADDRESS = (PROTOCOL = TCP)(HOST = loki.dev.justplus.ro)(PORT = 1521))
sqlnet:
NAMES.DIRECTORY_PATH= (TNSNAMES)
tnsnames:
SM_LOKI =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = loki.dev.justplus.ro)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = SM)
Oracle version is:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
When I try to start listener (lsnrctl status) I get the error:
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=loki.dev.justplus.ro)(PORT=1521)))
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
32-bit Windows Error: 61: Unknown error
Forgot to mention the OS: windows 2003
Any help is appreciated.
Thanks.

You didn't describe how you performed the upgrade process. But it looks like you performed a migration process instead. If there is no listener service listed it's because it has never been started, or even configured. You should use the netca or the network manager to configure the listener and start it. The first time it starts it shows an error on windows platforms because the service originally doesn't exist, once it is created it displays the listener status.
Please check the name resolution mechanism. If you are working on dhcp assigned IP or if you have a fixed IP. In case you are working with dynamic IP address you should configure a loopback adapter, and I suggest you reading this reference: Connectivity. Loopback Adapter.

TNS-12560: TNS:protocol adapter error (when starting database)

Hi.. everyone.
I am testing oracle9i and oracle10g on the same machine, windows xp pro.
When I was trying to start oracle10g using command line mode,
I got the error, TNS-12560: TNS:protocol adapter error.
I entered these command.
set oracle_home=10g_homexxxx
set oracle_sid=xxdb
sqlplus /nolog
conn sys/xxx as sysdba
I got the error, TNS-12560: TNS:protocol adapter error.
The install of two different versions of oracle , oracle9i and oracle10g,
on the same machine(windows xp pro) could cause this problem?
Is it safe to install two different versions of oracle on the same window machine?
Is there any confliction in environment variables?
I think there is no problem on the linux, unix system.
I stoped the listener of oracle9i and tried again. But I failed.
I am looking forwared to hearing your experience and advice.
Thanks in advance. Have a good day.
Ho.

Dear Werner.
Thanks for your reply.
I shutdown oracle9i and 10g, using "services.msc" utility from windows.
Therefore, "OracleService<xxdd>" is not running.
What I want to do is to startup 10g database using "cmd",command line mode.
In addition, I would like to know why I could not start 10g database, using "cmd"
on windows xp pro.
I installed 9i first and installed 10g. I think there are a kind of environment variable
conflictions.
I am wondering how I can fix them, and whether or not they are curable.
Thanks for your reply. Have a good day.
Regards.
Ho.
