• Oracle Forms 11g - ORA-12154: TNS error

  Well, until I post my info, I searched and searched all over Google, OTN, Experts-Exchange, etc... to try and figure this one out and I am puzzled. So here goes. I get the dreaded ' * ORA-12154: TNS: could not resolve the connect identifier specified * "error. This is my environment:

• ORA-12154 with 11g and heterogeneous services

  Hello
  I have a procedure that bring data from a mysql on a service of HS server.
  In 10G has worked very well, but after I migrated to 11g, weird things happen.
  If I ran the procedure (or work that calls it) directly from sqlplus, it's fine, but if I schedule a task to run this procedure, he breaks up with: ORA-12154: TNS: could not resolve the connect identifier specified.
  It's like some environmental parameters or the rights are missing when this work is performed automatically.
  So what's changed in 11g?
  
  
  Any help is appreciated,
  Thank you

  ORA-12154: ALWAYS occurs only on SQL Client & not SQL * Net packets never leave client system
  ORA-12154 NEVER involves the listener, the database itself or whatever it is on the DB server.
  ORA-12154 occurs when the client wants to connect to a DB Server system by using a connection string.
  AMT-03505 is thrown by tnsping & is the same error ORA-12154 thrown by sqlplus or others.
  The find operation fails because the supplied name can NOT be resolved at any remote DB.
  The analogous operation would be when you wanted to call someone, but did not find their name in any directory.
  The most common cause for ORA-12154 error is when the connection alias cannot be found in tnsnames.ora.
  The research of the alias operation can have an impact on the content of the sqlnet.ora file. DOMAIN entry specifically.
  So after the content of the sqlnet.ora file.

• ORA-12154 as user oracle, Pentecost root account, it works very well

  Hello
  
  I have a problem with a client installation, if I try to connect to the database. I have the following configuration:
  
  1 database: running on an Ubuntu Jeos VM, Oracle 11 g (11.1.0.6.0 version 64 bit)
  2. customer: running on a CentOS 5.2 VM, Oracle 10 g Linux 32-bit Client
  
  I have configured the tnsnames.ora and stored in the directory of $ORACLE_HOME/network/admin. The content of the tnsnames.ora file is the following:
  ORCL64 = (Description = (ADDRESS_LIST = (Address = (Protocol = TCP)(host=192.168.12.128) (port = 1521))) (CONNECT_DATA = (SID = ORCL)))
  
  If I try to connect to the database as the user oracle with the following command sqlplus SYS@ORCL64 AS SYSDBA, I will get the ORA-12154 TNS: could not resolve the connect identifier specified error message. If I try the same as the root user, it works fine and I can make the connection. I have the same result if I try the command tnsping ORCL64. As user root the tnsnames adapter can resolve the alias, as the oracle user this appears not possible and I will get the error message: TNS-03505: failed to resolve the name. In both it uses the setting from the file u01/app/oracle/network/admin/sqlnet.ora. The content of the sqlnet.ora file is the following:
  NAMES of . DIRECTORY_PATH = (TNSNAMES, EZCONNECT).
  
  Do you have any suggestions how can I solve this problem of having a connection with the oracle user.
  Thanks in advance

  Hello

  Thanks for your replies. On the CentOS machine, where the client is installed, there is no directory $ORACLE_HOME/bin/oracle and $ORACLE_HOME/bin/lsnrctl. The output of the $ORACLE_HOME/network/admin / * ora is:

  -rw - r - 1 oracle oinstall 171 28. Apr 21:25 /u01/app/oracle/network/admin/sqlnet.ora
  WX - 1 root root 118 5. May 11:33 /u01/app/oracle/network/admin/tnsnames.ora

  The 'client' reads the tnsnames.ora to determine where the database. Looking at t he above, you have a configuration in which the user name only client able to read the tnsnames.ora is the root user. Which means that you have run the netca or netmgr as root.

  Change the tnsnames.ora to provide the appropriate, perms and then try again.

  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.

• 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.

  Chinar,

  Sorry to bug you like this.

  Why can't hang in the database with a DB link when I can log the same database by using a client? And I thought that the tnsnames.ora on the client computer has been making analyzed to extract the server connection details.

  I have a couple of queries. I would really appreciate if you could answer or point me to a link that explains this:

  (1) the names of descriptor connect in tnsnames.ora on the client and server must always match? -(Je pensais qu'ils didn't doit).
  (2) most of the databases that I use the same request to connect to the server and the client, descriptor names. I tried to change, and I was hitting ORA-12154 more time, but not always. Why this behavior a bit?

  Thank you
  CJM

  When you use a db_link, the database in which the link is defined and referenced acts as a client to the target of the link. That is why the machine hosting the source of the link must now be considered the client computer, insofar as this db link is concerned.

  The connection string, you really used to connect knowing would have been helpful...

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

  This error means one thing and one thing only. The customer couldn't find the entry specified in the tnsnames.ora file being used.

  Following this statement, remember that when you use a dblink, the database that defines the link acts as a client to the database that is the target of the link. So in this case, the tnsnames.ora on the host of your source file must have an entry for your db target, as defined in the db_link.

  And for the umpteenth time... This error has NOTHING to do with the status of a listener. The connection request never got far enough to reach a listener. If someone tells you to check a listener in response to ora-12154, they do not pay attention, or do not understand how works the TNS. This error is equivalent to not be able to place a phone call because you do not know the number of the part you want to reach. You would not debug this situation by going to the home of the other guy and test his phone, or by accessing the phone company and the standard test. And you are debugging an ORA-12154 by checking the listener. If I had a list of ten albums of 'Incredibly Simple Concepts (tm)' which must be burned in the brain of anyone claiming to be an Oracle DBA, it would include "ORA-12154 has nothing to do with the listener.

  =================================

  Suppose you have the following in your tnsnames.ora:

  larry =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
      )
      (CONNECT_DATA =
        (SERVICE_NAME = curley)
      )
    )
  

  Now, when you issue a connect, say like this:

  $> sqlplus scott/tiger@larry
  

  TNS will appear in your tnsnames.ora for an entry called "larry". Then, tns sends a request to (PORT = 1521) on (HOST = myhost) to aid (PROTOCOL = TCP), requesting a connection to (SERVICE_NAME = curley).

  Where's (HOST = myhost) on the network? When the request is passed to tns to the next layer in the network stack, the name "myhost" resolves to an IP address, either via a file 'hosts' local, through DNS, or possibly other mechanisms being used less. Alternatively, you can hard-code the IP (HOST = 123.456.789.101) in the tnsnames.ora.

  Then, the request arrives at port 1521 myhost. If all goes well, there is a listener on myhost configured to listen on port 1521, and this listener knows SERVICE_NAME = curley. If so, you'll be connected.

  A few important points.

  First, the listener is a process only server-side . It's all in life seeks applications for reception for connections to the databases and set up these connections. Once the connection is established, the listener is out of the picture. It creates the connection. Is not maintain the connection. A listener, linking an oracle of the House, listening on a single port, use multiple instances of database in several versions of several houses. It is unnecessary complexity to try to have several headphones. It's like the telephone company, to build a separate table for each customer.

  Secondly, the tnsnames.ora file is a problem on the client side . Its purpose is to address resolution - the equivalent of the 'hosts' file tns further to the bottom of the network stack. The only reason it exists on a host computer is because this machine also can run client processes.

  What can go wrong?

  First, there may not be an entry for 'larry' in your tnsnames file. In this case, you get "ORA-12154: TNS: could not resolve the connect identifier specified" no need to go looking for a problem on the host, with the listener, etc.. If you cannot place a phone call because you do not know the number (cannot find your phonebook (tnsnames.ora) or can not find the party looking for listed in it (no entry for larry)) you don't look at problems at the switchboard.

  Perhaps the entry for larry was found, but myhost could not be resolved to an IP address (for example there is no entry for myhost in the local hosts file). This will mean by "ORA-12545: Connect failed because target host or object does not exist.

  Maybe there is an entry for MyServer in the local hosts file, but it specified a bad IP address. This will mean by "ORA-12545: Connect failed because target host or object does not exist.

  Maybe the INVESTIGATION period was good, but there is no listener running: "ORA-12541: TNS:no listener.

  Maybe the INVESTIGATION period was good, there is a listener to myhost, but he is listening on a different port. "ORA-12560: TNS:protocol adapter error.

  Maybe the INVESTIGATION period was good, there is a listener to myhost, listening on the specified port, it's unknown SERVICE_NAME = curley. "ORA-12514: TNS:listener is not currently of service requested in connect descriptor.

  I created a DSN from Data Sources (ODBC) (32-bit version of what in % windir%\syswow64\odbcad32.exe) pointing to an instance of Oracle 10 g.

  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.

  I get the error:

  ADO error: 0x80040E4D
  Exception occurred in the Microsoft OLE DB provider for ODBC drivers:

  [Oracle] [ODBC] [Ora] ORA-12154: TNS could not resolve the specified correct identifier

  all will help much appreciated

  Thanks in advance

  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.

• 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.

  Hi EdStevens,

  I used option TNS with Alias network as 'OCA010' in Sql Developer.

  I checked in tnsping and tnsnames.ora directory is correct.

  Please find below the exit of tnsping:

  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.

• I get an ORA-12514 in Oracle 12 c when restart Windows 2012

  Hi Mr President:

  I just installed Oracle 12 c in a 2012 Widnows Server. Sometimes, I get the famous ORA-12154 error - tns could not resolve the connect identifier specified. the problems occurs in two different servers. I think the problem is when I reboot the server, Oracle has a problem with the identifier name or database server / IP resolution.

  I fix"Database Management Wizard" running Oracle. When I run this application, the database comes to life. Can you explain to me what is happening? How can I fix or put in place to solve the problem?

  Thanks in advance.

  you need the administration for windows, not the dbca assistant

  

  This will give you the options to start automatically to your windows startup oracle

  

  

  Set the nt service starts automatically and also the oracle instance

  This should resolve the startup problem

  provide your listener will also start automatically...

  You can set to auto in services.msc
