Database connection works fine when connecting from the server itself( i.e. locally on the database server).
Is there anything still missing on the oralce client machine ?
Regards

Hi,
also below is the o/p of netstat -nr command
-bash-4.1$ netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
172.16.40.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 172.16.40.1 0.0.0.0 UG 0 0 0 eth0
seems some issue with IP address in the Destination column as the IP address of the database server machine is 172.16.40.64
may be this can be creating the problem.
If it is so, then in which file to change the IP address ?

Error ORA-12560:TNS:protocol adapter error - on client

dear frnds,
I am try to install oracle 11g to my client iam getting error
ORA-12560:TNS:protocol adapter error
pls help me out
thanx in advance

Most likely reason for TNS Protocol adapter error is....you must have older client FIRST in your path.
You 11g binaries are not kicking in, cuz...you must have 10g or similar/older binaries first in your PATH ( in windows )
In windoz...in cmd window...
set ORACLE_SID=xxxx
set ORACLE_HOME= to your 11g home
cd %ORACLE_HOME%\bin OR set PATH=%ORACLE_HOME%\bin;%PATH%
Then your sqlplus etc..
This time you should not be getting the protocol error.
Let us know whether this solved your problem

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.

Tarisa.

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:

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.

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.

ERROR:
ORA-12560: TNS:protocol adapter error
This is a local connection (called an internal connect in the old days). The connection does not go via the Listener. It is a local IPC connection. And as you can see, you do not supply a database schema and password as credentials - the o/s user and environment need to provide the credentials.
So I would not expect a TNS protocol adapter error, as this usually indicates a network driver related problem.
For a local IPC connection to work, TWO_TASK must not be set, and ORACLE_SID and ORACLE_HOME must be set (and valid). The local client driver needs to launch an Oracle server process (dedicated server process to service the client driver). It finds that executable in ORACLE_HOME/bin. Next it needs that server process to "attach" itself to the database's brains (the SGA). This shared memory area is identified via the ORACLE_HOME and ORACLE_SID variables.
There also is a requirement that the dedicated server process created, has the o/s permissions to attach to the SGA - which means it needs to be run as the same o/s user as the owner of the shared memory (in other words, the client should be running in the same o/s user as the database processes).
Thus the need to have these variables set. And no need for using a Listener - it is not a factor.

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 ?

ORA-12560 TNS:Protocol Adapter Error and ORA-12557 Error

Hello ,
I have installed Oracle 11.2.0 64 bit database on my Windows 7 ( Home Premium) PC which is also 64 bit. I installed it because I am trying to setup Informatica. Later, I learnt that informatica is 32 bit and can not communicate to Oracle 11.2.0 64 bit database. So after digging through solutions, someone mentioned that I need to install Oracle 11g client 32bit.
I have installed 11g client software successfully now. Here is problem though :
When I launch SQL-Plus from 11g database , it works fine. However I launch SQL-Plus from 32bit client it gives me error as :
Ora-12560 :TNS: Protocol Adapter Error.
So I have been trying to resolve this error. I saw that this question has been posted many many times and have tried many thing as listed below :
1. copy tnsnames.ora from database ( dbhome_1) to client installation ( client_1 ) under ..\network\admin\ --- Didn't work.
2. Set $ORACLE_HOME and $ORACLE_SID environment variable.
Here is interesting fact - If I set $ORACLE_HOME to database path and not client path error changes to :
ORA-12557 TNS: Protocol adapter not loadable.
If I keep $ORACLE_HOME as client path then I get same error as earlier ORA-12560.
3. I have also tried changing $PATH variable. I did set to path containing only database installation, only client installation, both database and client installation with database installation appearing first
But all of these haven't worked.
Can anyone please suggest what I am missing and any further things I could try ?
Thank you in advance !

Thank you in advance !unfortunately, we need to know exactly how you tried to connect with sqlplus when it "worked" and when it "didn't work". The key to the reported error messages is highly dependent on the environment settings AND the specification of the connect string. A copy and paste of the entire command line session would be most helpful.
But again, running on any 'home' edition of windows is not supported.

Ora-12560 tns protocol adapter error (can connect with cmd line creds only)

SQLPLUS returns the following when trying to log in with user/pass:
ora-12560 tns protocol adapter error
Have tried setting ORACLE_SID=VMFG, etc, before launching SQLPLUS, still does not work, though if I do this:
SQLPLUS SYSADM/SYSADM@db1/VMFG
it works, which is probably something to do with tnsnames.ora or sqlnet.ora which I copied from our database server? I added the SYSADM/SYSADM account and gave it db rights to VMFG (the db name).
This is a new installation. What am I doing wrong? tnsping db1 returns pongs, testing the service with the oracle client returns success when I change the u/p to SYSADM/SYSADM. Thanks in advance!

ORA-12560: TNS:protocol adapter error while creating new database

Hi,
I installed Oracle Enterprise Manager 10g Grid Control Release 1 (10.1.03) and created the default database it had which was emrep. Once Oracle Grid Control was installed I ran the install for Oracle Database 10g Release 1 (10.1.0.2).
Now when I try to create a database I get the following error: ORA-12560: TNS:protocol adapter error.
My assumption is because I seem to have 2 Oracle home's now because I installed the Grid Control??
My question is, have I done this backwards? Should I install Oracle 10g before installing the grid control? If thats not it, can someone point me in the right direction?
FYI: The server we're using is running Windows Server 2003.
Thanks for your help

I don't know what else I could have done given the behavior of the service.You can avoid problems like this in the future by avoiding Windows & using any approved *NIX Operating System.
No such "service" or daemon exist on any *NIX OS.

ORA-12560: TNS: protocol adapter error while linking tables in Access

One of my app dev is encountering an interesting error message while linking Oracle tables from Access. I am not able to able to reproduce this in my desktop or anywhere else. Details enclosed. Can you guys point me to a solution? Thanks in advance!
ODBC: Oracle Client version 10.2.0.1
Desktop : Win XP ; Access 2003
=>Able to login to the Oracle database sucessfully using sqlplus.
=>Able to create an ODBC datasource to Oracle database.("Test Connection" works fine)
=>But encountering the TNS protocol adpater error while linking the table(Access->File->Get External Data-> Link tables).
=>Not able to link any table in any schema in any Oracle database. Hence this is not a data centric issue.
What did I do?
=> Uninstalled Oracle 8 client and installed Oracle 10 client. No luck. Encountering the same error.
=> Turned on the ODBC trace and reproduced the error. The log is enclosed:

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.

ORA-12560: TNS:protocol adapter error after patch 9.2.0.7 on Windows2K

I just install the patch 9.2.0.7 for client Oracle machine on windows 2000 server.
Since then I'm constantly getting "ORA-12560: TNS:protocol adapter error" and I cannot connect via SQL plus.
Any help is appreciated, mj

I'm trying to connect to databases that are running on a separate machines - aix5.2, and I can connect from every other machine in the office but not from this one.
There's no database on this machine - only Oracle client tools installed with 9.2.0.1 and then updated to 9.2.0.7. Before the update the sqlplus was working just fine. After the patch run, I'm not able to connect viw sqlplus.
There were no errors when running the patch.
Thanks a lot,mj

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=
