• 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.

• 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.

  Best regards

  I found the page "which versions of Oracle of Toad for Oracle support?

  What version of Oracle 10 is the question?

  Published by: mseberg on July 22, 2011 15:47

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

  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.

  Hello
  It is not related to Toad, check the TNS entry in your TNSNAMES.ora & make sure what is it pointing to the appropriate service name.

  -------------------------------------------------------------------------------
  Cause: The specified service name is not defined correctly in the

  Action: Perform the following checks and fix the error:
  -Check that a TNSNAMES file. ORA file exists and is in good

  For more information on the location and the name required.
  -Check that the name of the service exist in one of the

  I was saying about the environment variables defined by you on the server of informatica/dac under the .profile or .bash_profile as below:

  TNS_ADMIN = $ORACLE_HOME/network/admin; Export TNS_ADMIN

  ORACLE_BASE = / home/oracle/app/oracle; export ORACLE_BASE

  ORACLE_HOME=$ORACLE_BASE/product/11.2.0/; Export ORACLE_HOME

  ORACLE_SID = InstanceName; export ORACLE_SID

  Path = $PATH: / usr/sbin: $ORACLE_HOME/bin. export PATH

  LD_LIBRARY_PATH=.:$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH

  CLASSPATH = $ORACLE_HOME/jlib: $ORACLE_HOME/rdbms/jlib. Export CLASSPATH

  Here are some examples I mentioned everything. You can set them in the user profile from which you installed the server informatica/dac.

  If it is a CAR Forum, try to set the value of the instance-specific SID for example: orcl11 or orcl12 or orcl13... try to connect to each instance. Sometimes the general SID does not recognize configuration

  Hello everyone.

  I already solved the problem (work until late Saturday).

  the solution was to install the latest version of the Oracle customer, namely: Oracle 11 g Release 2 CLIENT for Windows 32 (11.2.0.1.0).

  Now everything works OK.

  I also tested in Windows 7 32 bit (the .vi even and the same Oracle client). This will also OK.

  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.

  You can remove your tnsnames.ora if he isn't there the other TNS inside. and use netmanager

  Concerning

• Mover - ORA-12154: TNS - problem

  Hello
  
  My system: Windows Server 2003 32-bit. Oracle DB 10.1.0.2.0; PT 8.52; HCM 9.0;
  
  I have error when connecting to Data Mover:
  
  File: Error SQL Access ManagerSQL. Stmt #: 2 error Position: 0 return: 12154 - ORA-12154: TNS: could not resolve the connect identifier specified
  
  I add in tnsnames.ora and listener.ora record for my DB:
  
  tnsnames.ora:
  
  HR9 =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP) (HOST = LNZ-PS90)(PORT = 1521))
  (CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = HR9)
  )
  )
  
  Listener.ora:
  
  )
  (SID_DESC =
  (SID_NAME = HR9)
  (ORACLE_HOME = E:\oracle\product\10.2.0\db_1)
  )
  
  Restart the listner but it doesn't work I can not connect to DATA MOVER, please help.

  Add SID, which means something like that

  HR9=
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = LNZ-PS90)(PORT = 1521))
      )
      (CONNECT_DATA =
        (SERVICE_NAME = HR9)
        (SID = HR9)
      )
    )
