  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.

  Hi all

  I create a portfolio of oracle and everything works fine until a script is launched by the OS oracle user. (same user that whoever created the store)

  I use authentication external store and inside my script, I do something like a sqlplus / @MYSECURE_TNS.

  However, when I run a script OS another user as a 'data_loading_user' I get the error: Oracle Database Vault ORA-12578 connection error: TNS:wallet open failed

  Hi all

  Tried something out of the blue, that has worked.

  I added the data_loading_user of the user to the group administrator (Group of BONES that created the wallet).

  The I added the read permission to the group, so the permission on the files below were 640:

  # > chmod 640 cwallet.sso

• "ORA-12154: TNS: could not resolve the connect identifier specified" error executing the execution in CAD Plan.

  Hi friends,

  We do face-down question when executing the execution Plan in DAC for full charge. We are working on the project of modernization of the OBI Applications and my client has worked on this environment is a few days. Before this, they load to the source 'EBSTST' instance and now changed data for instance 'EBSWKLY '. We have changed the details of connection under the tab 'Physical Data Sources' DAC. Test the connection Source and target are good. We have added input TNS of EBSWKLY in the path: u01/app/oracle/oracle11g/product/11.2.0/client_1/network/admin.

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

  Database driver error...

  Function name: connect

  [The database error: could not connect to the database using the [apps] user and the connection string [EBSWKLY].].

  Please suggest me if I m done mistake anywhere...

  Thanks in advance.

  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

  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.

  I am facing the following problem:

  labVIEW 2012 32 bits 64 bits of Windows 7, 10.2.0.1.0 oracle client (32-bit).

  I have test the DSN in this way (IE. Data sources (ODBC) and the connection is successful (which means that the tnsnames.ora is correct).

  I use the "DB tools Open Connection.vi" in order to get connected to this database, passing as parameters the DSN above, the user name and password.

  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.

  Thans a lot.

  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,.

  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.

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

  https://support.quest.com/search/SolutionDetail.aspx?ID=SOL21018

  What version of Oracle 10 is the question?

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

  (1) I have TNS entries under MW_HOME/OracleBI/network/admin
  (2) TNSPING works fine.
  (3) source updated JDBC in place on the side WLS...
  
  
  What should I do?

  Show complete exception stack trace. This does not seem to relate to WebLogic. The WebLogic console
  view running data source? In fact you use WebLogic DataSource?

• 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.
