• .Mdb MS Access using ODBC connection failed to resolve ORA-12154 connection identifier

  Dear all,

  I am using the MS Access file .mdb as the source of my request for OWB. I need to connect to the ms access .mdb file first using odbc. This is the step that I do:

  1. define the ODBC connectifity

  Control Panel-> admin tools-> data-> system-> add DSN sources

  Select Microsoft Access Driver (*.mdb)-> Finish

  Data source name: msaccess-> database: Select-> location of the file .mdb (C:\MSAccess\att2000.. (MDB)

  2 configure the listener

  SID_LIST_LISTENER =

  (SID_LIST =

  (SID_DESC =

  (SID_NAME = CLRExtProc)

  (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)

  (= Extproc PROGRAM)

  (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")

  )

  (SID_DESC =

  (SID_NAME = msaccess

  (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)

  (PROGRAM = hsodbc)

  )

  )

  LISTENER =

  (DESCRIPTION_LIST =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = CIP)(KEY = EXTPROC1521))

  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost) (PORT = 1521))

  )

  (SID_DESC =

  (SID_NAME = msaccess

  (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)

  (PROGRAM = hsodbc)

  )

  )

  ADR_BASE_LISTENER = C:\app\Administrator

  3 Configure Oracle HS

  File name Initmsaccess.ora

  #

  # HS init parameters

  #

  HS_FDS_CONNECT_INFO = msaccess

  HS_FDS_TRACE_LEVEL = 1

  #

  # Required for the non-Oracle system environment variables

  #

  #set < varenv > = < value >

  4 edit tnsnames.ora

  Msaccess =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost) (PORT = 1521))

  (CONNECT_DATA =

  (SID = msaccess)

  (SERVICE_NAME = msaccess)

  )

  (HS = OK)

  )

  5. create the database link

  create the link msaccess database using "msaccess";

  6 execute a query to test the connection

  SQL > select * from departments@msaccess;

  ERROR on line 1:

  ORA-12154: TNS: could not resolve the connect identifier specified

  I check the AMT using msaccess tnsping, it returns

  TNSNAMES adapter used to resolve the alias

  Try to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhos)

  (t) (PORT = 1521)) (CONNECT_DATA = (SID = msaccess) (SERVICE_NAME = msaccess)) (HS = OK)( )

  OK (120 MS)

  Any body knows how to solve this problem?

  Best regards

  Akhmad H Gumas

  Akhmad,

  just to confirm that I understood:

  You have an Oracle database and the bridge installed on your machine. The database and the bridge are all part of this Oracle_Home: C:\app\Administrator\product\11.2.0\dbhome_1

  Fix?

  When you look at your listener.ora file it lack a right bracket:

  (SID_NAME = msaccess

  => should be (SID_NAME = msaccess)

  Once done, please STOP and START the listener.

  Then open a command line window and type:

  Set ORACLE_HOME=C:\app\Administrator\product\11.2.0\dbhome_1

  Status of C:\app\Administrator\product\11.2.0\dbhome_1\bin\lsnrctl

  C:\app\Administrator\product\11.2.0\dbhome_1\bin\dg4odbc

  C:\app\Administrator\product\11.2.0\dbhome_1\bin\tnsping msaccess

  And copy and paste the output of each command.

  Hello

  I see just a glance on the tnsnames file you are missing at least one sign =...

  You have

  ORCL

  (DESC...

  You should have

  ORCL =

  (DESC...

  There may be other issues too, but give that a try at first - you better run netmgr to allow oracle to create the file for you.

  I've learned to trust in your obfuscation you covered something important, or you are showing some apples and oranges.  Error to declare you come from not being able to find referenced in tnsnames.ora entry, but the way you say you created your link db, you hardcoded the entire connection, so he never users tnsnames.ora.

  I would change the definition of db_link

  create the database link * _DBLINK

  connect to the USER IDENTIFIED BY 'user '.

  using "REM."

  Then create an entry in your tnsnames.ora

  REM =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP) (HOST = *. *. *. *)(PORT = 1521))

  )

  (CONNECT_DATA = (SERVICE_NAME = REM)

  )

  )

  Also, use server name instead of the HOST = IP address

  The closer looks that you can miss brackets final closing on your original definition.

• Unable to connect, ORA-12154, the installation routine to find ODBC Microsoft errors

  It is enough that one of them (the other should be enough).

  I launched the ODBC data sources administrator and added a user DSN but gave rise to two errors:
  1. the Setup for the Microsoft ODBC driver ODBC routines oracle is not found. Please you reintall the pilot.

  "Microsoft ODBC for Oracle" is a different provider than 'Oracle ODBC'. Make sure that you do not use Microsoft one.

  2. the specified DSN contains a mismatch of architecture between the driver and the application.

  This can happen if you mix 32-bit and 64-bit. There are two ODBC Control Panel in Windows 7:
  -64-bit, one is that of the Panel
  -the 32 bit one is c:\windows\syswow64\odbcad32.exe

  Because you use an Oracle 64-bit driver, you must use the 64-bit ODBC Administrator and 64-bit applications. If you try to use this ODBC connection with a 32-bit application, you will need to use the 32-bit ODBC (and the driver Oracle 32-bit).

  In addition to that, if I go to the system DSN tab and tried to test the connection it gives me an error:
  1. cannot connect SQLState = 08004 [Oracle] [ODBC] [Ora] ORA-12154: TNS: can not solved the specified identifier.

  Well it actually means that it loads correctly, Oracle is something. You must add an entry for the server you want to connect in tnsnames.ora, located in the folder \network\admin inside your Oracle client installation. Because it looks like someone else set up the server that you want to connect, your DBA should be able to provide the information that is written to the file.

  In my PB, I have two database:

  D:\ORACLE\db\product\11.2.0\dbhome_1
  D:\ORACLE\db\product\11.2.0\dbhome_2
  

  What do you evidence isn't two databases, it is two ORACLE_HOMEs. In other words, two installations of the RDBMS software. Do NOT confuse the software with a database.

  This and the rest of what you post in this thread shows a real misunderstanding of how oracle in general - and tns in particular - works.
  I suggest you start here > http://edstevensdba.wordpress.com/2011/02/09/sqlnet_overview/, and then follow up with some time spent in the manual of Concepts to tahiti.oracle.com

  When I check using lsnrctl status, is the location of listener.ora:
  D:\ORACLE\db\product\11.2.0\dbhome_1\network\admin\listener.ora

  and my listener entries are in the file D:\ORACLE\db\product\11.2.0\dbhome_1\network\admin\listener.ora...

  and I was checking the D:\ORACLE\db\product\11.2.0\dbhome_1\network\admin\listener.ora file and give the same entries...

  I'm always confused with this problem

• Able to connect to SQL Developer but not a toad - ORA-12154: TNS

  My workplace uses TOAD as standard SQL tool to run against Oracle, although I prefer test and use SQL developer.
  
  When you try to connect to a database in TOAD I get the following error
  
  ORA-12154: TNS: could not resolve service name
  
  I'm using the TNSNAMES file. ORA and I am able to connect through SQL Developer, no problem.
  
  Also in the same file, I'm able to connect to the other TNS names, but all just not this one it seems.
  
  I find it very strange, because it seems that for this name TNS one, I specifically can not connect through TOAD
  
  I can connect to any other AMT via TOAD, and I can connect through SQL developer
  
  I also tried a TNSPING and his returning in OK for the server and the connection seem just.
  
  I am trying to connect to an Oracle 10 g with TOAD version 8.0.0.47 Server
  
  Any ideas appreciated!

  I'm doing this from memory, but...

  Oracle 10g database with TOAD version 8.0.0.47
  

  I believe that your version of toad is too low for this version of Oracle. You should be able to confirm with QUEST software.

  My rule with Toad's (once you get past the version number), if you cannot connect using SQL, Toad will never work.

• OBIEE 11 g, ORA-12154: TNS: could not resolve the connect identifier

  HI forumer,
  
  I installed obiee 11g and I am trying to connect to oracle 11 g db installed on the same machine. I am able to create the DSN using the tnsnames.ora, but the same details used with obiee work not and fails with:
  
  ORA-12154: TNS: could not resolve the connect identifier
  
  Appreciate any help in this.
  
  Thank you

  This is a change in behavior when we have 10g and 11g. In BI EE 10 g, there was no Oracle Client delivered with BI EE. Thus, BI EE will use your Oracle DB client host to connect to the database. Usually not a problem in this case. But in BI EE 11 g, the software itself contains a client of 11.2 DB. Thus, when you try to connect to the database using the repository or the BI server, it will try to find the tnsnames entry in the customer Oracle of BI EE 11 g instead of your database. There are 2 options to work around this problem

  1. copy your tnsnames.ora {Oracle_BI1} \network\admin directory & {oracle_common} \network\admin directory (only the first is necessary because it is the ORACLE_HOME)

  2. or instead of the source tnsnames.ora entry, use the full expanded tnsnames as shown below

  (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP) (HOST = 172.16.66.173)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED)(SERVICE_NAME = orcl)))

  Both of the above will work.

• ORA-12154: TNS: could not resolve the connect identifier specifier (XE)

  Hello
  
  «I installed on my laptop with win 7 Oracle Database 10g Release 2 (10.2.0.1) Express Edition for Microsoft Windows, but when I tried to connect with Toad for Oracle Freeware 10.6 I get the following error ' ORA-12154: TNS: could not resolve the connect identifier specifier (XE)» I read on the forum that the problem comes from the wrong configuration of the AMT.

  Can someone tell me what is the problem?
  
  Best regards

  It can be caused by the location of the TOAD software. The have you installed under "Program Files (x 86)? If Yes, then try to reinstall in a different directory, media in the path name can cause problems.

• ORA-12154: TNS: could not resolve the specified connection identifier [10g XE]

  Greetings
  
  There are a lot of topics about this problem on the internet, but none of them deal with this issue properly, so I couldn't find a solution to the problem.
  
  I installed: Oracle Database 10 g Express Edition
  
  After that the installation was done, I opened the SQL command line
  and I used the command "connect" to connect
  I enter username
  Then I entered the password
  
  After a few 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 Windows XP 32 bit and Windows 7 32 bit and I get the same error message when it tries to connect.
  
  Why Oracle does not immediately after installation?
  Are there other measures that need to be accomplished in order to make this work? If so I'd appreciate any help step by step, I was stuck trying to find a solution for days.

  >
  I was able to connect using the above command, but I would like to know why can't connect using a user name and password? I still cannot connect using a user name and password even after the environment variable.
  >

  The problem is that the normal user accounts are either locked, you use is maybe not the right password or they may not have the necessary privileges to establish a session (there are a number of reasons).

  Since you are in the console database, you don't need the environment variable set. SQL * Plus Gets the location of your database in the registry.

  Make the alter statement that I posted earlier for a user which you know that there is and we'll take it from there.
