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.

  • 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                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               

  • ORA-12560: TNS:protocol adapter error with samples

    hello,
    I am trying to run the cdemo1 sample on Windows 2000 but I keep getting the ORA-12560: TNS:protocol adapter error. I have set the correct username and password in cdemo1.c before compiling.
    I am using Oracle 9i and I have the Oracle Client installed.
    I am able to connect to Oracle using the command line with the following command sqlplus qa/tester@TESTSERV and I am also able to connect to Oracle using the Sqlplus Net8 client interface.
    I have set ORACLE_HOME on the command line to the path of my oracle home directories. And just for kicks I have also set the ORACLE_SID on the command line to TESTSERV
    My tnsnames.ora is configured properly
    TESTSERV.COMPANY.NET =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = PEPSI)(PORT = 1521))
    (CONNECT_DATA =
    (SID = TESTSERV)
         (SERVICE_NAME = TESTSERV.COMPANY.NET)     
    None of the methods seem to work.Anyone have any ideas why I can't connect with the cdemo1 but I can connect using command line and SQLPLUS?
    -Will

    I have had a similar problem with 8.1.6 on W2K Server. I have managed to get around it and get into svrmgrl by typing the following at the command prompt: set oracle_sid=sid_name. I am then able to get into svrmgrl without a problem. This always happens after the server has been rebooted. I have no idea why this happens or why setting the sid name works. Hope this helps.

  • Oracle Database 11g Installation Issue: ORA-12560:TNS: protocol adapter error.

    Folks,
    Hello. Initially, my Windows XP host name is "localhost" and IP address 127.0.0.1.
    I installed Oracle Database 11g with Windows XP successfully and all Database clients work with Database instance correctly.
    For some reasons, I uninstalled the entire Database Server and delete the entire installation directory /oracle.
    I configured Windows XP IP address into 192.168.196.101 in order to ping other machines.
    For my need, I installed Oracle Database 11g with Windows XP again. On step 7 of 8: Oracle Database Configuration Assistant, I got this error:
    ORA-12560:TNS: protocol adapter error.
    I click "Password Management" button, there are no rows in this Windows (no username, no lock accounts).
    I check listener as below:
    C:\>lsnrctl
    LSNRCTL>start
    Its output: listener name LISTENER has already been started.
    LSNRCTL>status
    Its output: ......Service DB1 has 1 instance. Instance DB1 status ready. The command completed successfully.
    I check \Oracle\cfgtoollogs\dbca\DB1\trace file, the entry is :
    listen[0]=LISTENER address=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(port=1522))
    I also check \oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\SAMPLE\tnsnames.ora file and listener.ora file, the entries are the same as below
    HOST=localhost  port=1522
    I think HOST=localhost and port=1522 is the cause of the error ORA-12560 because Windows XP has been configured into HOST=192.168.196.101.
    But I don't understand how to solve this issue.
    Can any folk tell me how to solve this issue ? need to cancel the installation on step 7 of 8 and install it again ?
    Thanks.

    Folks,
    Hello. Oracle Database 11g Installation Wizard is on step 7 of 8. I don't cancel the Wizard. I am not sure whether there is effect or not. listener.ora is not removed. I have been waiting for a while after stop listener.  I run the 3 commands again and copy the result as below:

    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.

  • ORA-12560 TNS protocol Adapter error in 11g (11.1.0.6)

    Hello All,
    I have Oracle 11g installed on my machine and when i tried to log in to sql plus i got the error below:
    ORA-12560 TNS protocol Adapter error
    By setting the ORACLE_SID = orcl by browsing to the bin directory of Oracle Installation the above error disappaears and i am able to log in from sql plus.
    My intention is to create a db backup for which i am trying to use the exp command...this time the same error appears.
    Also the solution of setting the ORACLE_SID is cumbersome..everytimt i want to use sql plus i need to go in and set the ORACLE_SID.
    Can anybody please help me out find a good solution for this?
    Any help would be appreciated friends.....
    Thanks in Advance!!!!!
    Regards.
    Alicia

    Also the solution of setting the ORACLE_SID is cumbersome..everytimt i want to use sql plus i need to go in and set the ORACLE_SID.
    Can anybody please help me out find a good solution for this?The solution depends on your (not specified) operating system...
    Anyway, if you have more than one database it's normal that you have to set ORACLE_SID, if not how can Oracle know which database you want to access to ?
    You can create batch files, one per database, or you can use connection strings, e.g. sqlplus username/password@<DB>.

    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 ?

  • 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 - startup mount on windows

    hi all,

    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.

  • 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

    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=

  • ERROR:ORA-12560: TNS:protocol adapter error

    I am using Win XP Pro. 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.
    I am new to Oracle. Please give me the steps how to fix this error to be
    able to run SQL+.
    Many thanks

    When starting server manager the following error is generated:
    ORA-12560: TNS:protocol adapter error occurred
    Cause:
    Oracle classify this as a 'generic protocol adapter error'. In my experience it indicates that Oracle client does not know what instance to connect to or what TNS alias to use.
    Possible Remedies:
    * If running on the server (or workstation) that is running the database (i.e. if the database is local to the machine) then try explicitly setting 'ORACLE_SID'. e.g.
    set ORACLE_SID=<sid>
    and then try again. If this works then consider whether to make the change permanent by specifying it as a system variable.
    FOR RUN THIS SID PLEASE REFER IT
    Go to command prompt
    C:\Document and settings\ORANGE> cd\
    C:\> set oracle_sid=<DB name>
    e.g C:\> set oracle_sid=<rajesh> {press enter}
    C:\> sqlplus /nolog {press enter}
    sql:\>connect sys/sys as sysdba {press enter} it cant ask for password directly connected

    Thanks in advance

    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.
