• DB Link error: ORA-12154: TNS: could not resolve the connect identifier specified

  Hi all

  We need to make an entry in the tnsname.ora file in a local database to connect to the remote database using db link?

  Here is my code: -.

  create the database link * _DBLINK

  connect to the USER IDENTIFIED BY 'user '.

  using '(DESCRIPTION =)

  (ADDRESS_LIST =

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

  )

  (CONNECT_DATA = (SERVICE_NAME = REM)

  )';

  After the creation of the DB connection when I'm trying to run select 1 of dual@***_DBLINK

  He throws me an error ORA-12154: TNS: could not resolve the connect identifier specified

  Am I expected to do an entry in the file tnsname.ora for "REM". I don't remember making any changes in the file tnsname.ora for the creation and access of the remote database via dblink.

  Help, please.

  Thanks in advance.

  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.

• ORA-12154 error trying to connect with the customer instant g 11 / LDAP on Ubuntu

  Hello
  
  I managed to install the client instant 11.2.0.2 and sqlplus on my Ubuntu 11.04 desktop. I am able to connect successfully to DB defined in tnsnames.ora, but when the resolution is (or should be) by LDAP, I get error
  
  ORA-12154: TNS: could not resolve the connect identifier specified
  
  Note: while it is fine for the test, it is not a viable option to configure all DB defined in the OID in tnsnames.ora - I need to use LDAP.
  
  My configuration is:
  
  Installation folder: / opt/oracle/instantclient_11_2
  TNS_ADMIN = / opt/oracle/instantclient_11_2 /.
  
  SQLNET.ora
  NAMES. DIRECTORY_PATH = (TNSNAMES, LDAP)
  
  I am sure that the tnsnames.ora and ldap.ora are valid, as I can connect on another machine with the full client installed successfully by using the same files.
  
  I tried tracing facility in sqlnet.ora as follows
  TRACE_LEVEL_CLIENT = SUPPORT
  TRACE_DIRECTORY_CLIENT = / tmp
  TRACE_FILE_CLIENT = sqlnet.trc
  but not the trace file is generated in the directory/tmp - I'm doing something wrong? (Note, I also tried to set DIAG_ADR_ENABLED = OFF as suggested by Laurenz Albe in Instant client do not trace but which did not help)
  
  I checked DocID = 359206.1 but I don't think that this applies as I am on 11 g.
  
  I hope someone can help. Thanks in advance!

  It might be the return transport of the characters in the parameter files - make sure your sqlnet.ora and ldap.ora are in Unix format.

  Linux vi versions tend to switch seamlessly between unix and back mode so it isn't always obvious - you can check with something like "od - c sqlnet.ora.

• A question about the CREATE DATABASE LINK PUBLIC and ORA-12154 error

  Hi all
  
  
  I have a problem on the public database link creation and I would be grateful if you could kindly give me a helping hand. I have the following connection settings in my
  tnsnames.ora file:
  

  ...
  DGPAPROD.WORLD = 
       (DESCRIPTION = 
         (ADDRESS_LIST = 
          (ADDRESS = (COMMUNITY=tcp.world)
            (PROTOCOL=TCP)(HOST=ORASR001)(PORT=1521)
           ) 
         )
         (CONNECT_DATA = (SID = DGPAPROD))
      )
  ...

  Having the above mentioned parameters, I can connect to this remote database directly in a SQL * more shell:

  $ sqlplus username/[email protected]

  It works pretty well and the connection is established without any problem.
  
  Now, what I want to do is to create a public database of this remote database link to avoid the user/connection of switch for the visualization of the
  the content of this database. I proceeded in line with the syntax indicated in the Oracle online documentation:
  
  http://download.Oracle.com/docs/CD/B28359_01/server.111/b28286/statements_5005.htm#SQLRF01205
  
  This is why I run the following to create a public database link

  CREATE PUBLIC DATABASE LINK SR001_dblink CONNECT TO user IDENTIFIED BY password USING 'DGPAPROD.WORLD';

  Apparently there is no error and the link is created successfully. However, it cannot resolve the remote host and every time I run this query
  (myenterprise is the name of a table in the remote database)

  SELECT *
  FROM myenterprise@SR001_dblink
  
  ERROR at line 1:
  ORA-12154: TNS:could not resolve the connect identifier specified

  What causes this problem?
  
  Thanks in advance,
  
  
  Kind regards

  You must have defined DGPAPROD. WORLD in tnsnames.oar on the server where DB is runnig.

  Have you worked from the link I provided?  (I don't think you have time to do).

  It is possible that your tnsnames.ora is corrupted by some weird characters printable somewhere.  In some versions of the oracle, he might be sensitive to spaces vs. tabs.  If in doubt, netca to add entries, rather than doing it by hand.

  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.

  See you soon,.

  When I posted my first response, I guess you are trying to connect to your database that is running on the same server, i.e. locally. So I wanted to make sure DOB connections are ok. But appearantly not. You get the ORA-12560 error when "/ as sysdba".

  To do so below if my hypothesis is correct:

  1. go to the command prompt
  2. set the ORACLE_HOME =
  3. set ORACLE_SID =
  4. set the path ="/ bin"
  5 sqlplus "/ as sysdba".
  If it works, output
  6. now try sqlplus .

  Paste the result.

• How to overcome ORA-12154 on afdbprf.sh and adcrobj.sh in Autoconfig

  I'm cloning a database uses the same set of scripts I used for two years without problems.  This, however, when I ran adcfgclone.pl dbconfig it failed during the automatic configuration.  The error is Autoconfig 2 status while the detail in the paper shows ORA-12154.

  I put the code in the templates afdbprf.sh and adcrobj.sh at the exit of the connection, connection and env, which look all right.  I can use this same set up the environment to run the sql code requested in these shell scripts and it connects fine.  This left me in the lurch because why this behavior in adconfig.

  I'm under EBS 12.1.3 on RDBMS Oracle Linux 11.2.0.3.  I created an SR that has proved so far a vain effort as the first, I was told to use a different document because I am on EBS 11.5.9, that I had to correct them, and then I was told to apply 7 different patches and let them know when I did when 4 of these patches have for database 12 c 1 was a fix for what one of the hotfixes 12 c breaks, another was for CARS and we are autonomous, and the last was a component of specific applications difficulty when our question database layer.  In other words, none of them applied, and despite sending newspapers, there is no indication that the analyst tried to identify the problem yet.

  I hope that the community here may be able to give assistance to help me go beyond this issue, or at least still identifying a root ask so I can find a solution.

  I will close this thread claiming that rename the ifile so that custom parameters are eliminated, and their restaurant then at the end the clone was the solution.  It takes a client specific configuration so autoconfig works with generic parameter sets, he expects.  The ifile can be renamed after the clone so they can be used by the finished system.

  OK (120 MS)

  Any body knows how to solve this problem?

  Best regards

  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.

  DATABASE: PDBORCL

  error 12154 appear

  It's perfectly normal: what you type in the DATABASE is not the service or database name, but a tns alias in tnsnames.ora. If your tnsnames.ora is the one you posted, PDBORCL isn't there (see the description of the error in my post above).

  We face below error when db creating different patterns of n/b two link (on the same database).

  create database link "db_Test1" to connect to test1 identified by 'password' using service1;

  I hope that this seems to be a syntax error...
  Try as below

  SQL > create database link db_Test1 connect to test1 identified by password using 'service1 ';

  the service name must be in single quotes... someone has already suggested above.
