• Oracle BI developer Client tools without Tnsnames.ora

  Hello gurus,
  
  
  In my local computer of the user, I installed Oracle BI developer Client Tools version 11.1.1.6
  It allows us to open a repository online/offline without installing OBIEE and Oracle database in our user, just put in ODBC connection.
  But the problem is when the user want to try to create the new repository, it seems that "the connection failed".
  There we have to copy some tnsnames.ora? In our local computer of the user, there is no tnsnames.ora since it does not install OBIEE/Oracle database on the local computer.
  
  Help, please
  
  
  Thanks in advance
  
  See you soon,.

  Hey Joe,
  If you import data from an oracle database. You must install the Oracle database client. Then only, you can import data from Oracle database.
  In addition, you are supposed to copy file ora, TNSNAMES.

• customer will not use the correct tnsnames.ora file

  Hello all, I installed oracle 10g client on my machine... but here's the thing... I tnsnames.ora several file on my machine (which I can't delete or play with)... and because of this oracle is not able to connect to the database I want it to connect to... I can't do tnsping to the database... is there a way where I can point my client to use a specific tnsnames.ora file? as a pointer? or something where it will look in this file specific tnsnsame.ora?

  You can specify what tnsnames.ora for use the TNS_ADMIN environment variable
  Switch to the directory that contains your tnsnames.ora to use.

  Kind regards

• DBD::Oracle and instant client - can't find tnsnames.ora

  Hi all! :-)

  Guys, please, help!

  My OS: CentOS 6.6, i386

  Installed:

  Oracle - instantclient12.1 - devel - 12.1.0.2.0 - 1.i386

  SELinux disabled.

  ORACLE_HOME = usr/lib/oracle/12.1/client, LD_LIBRARY_PATH = /usr/lib/oracle/12.1/client/lib

  tnsnames.ora exist in /usr/lib/oracle/12.1/client/network/admin

  I wrote a simple perl script to test the connection:

  use strict;
  use DBI;
  
  my $dbh = DBI ->connect("dbi:Oracle:crm", 'login', 'password',{RaiseError => 1} );
  $dbh->disconnect();
  
  

  When I try to run script command line - everything isn't ok, no errors (Yes, I can run queries, etc... )

  But!

  With apache, I get an error:

  DBI connect('crm','login',...) failed: ORA-12154: TNS: could not resolve the connect identifier specified (DBD ERROR: OCIServerAttach) in /opt/otrs/bin/cgi-bin/oratest.pl on line 9

  I am trying to add ORACLE_HOME with PerlSetEnv and script see (I checked through % ENV), but no luck.

  Probably easier to use EZconnect instead of tnsnames.ora:

  $machine = 'my.oracle.database.com';
   $port = 1521;
   $sid = 'my_sid';
   $dbh = DBI->connect("dbi:Oracle://$machine:$port/$sid", $user, $pass) ||
    die "Failed to connect: $DBI::errstr\n";
  

• Oracle TNS not getting format not recognized

  Hi all

  I have two installations in my system:

  Oracle 10g

  Oracle, forms and reports 6i - Oracle8

  I don't know in what order its been installed, it came with my installation of windows office directly.

  The problem is with the TNSNAMES file.

  The tnsnames.ora file is being levied on the 'C:\Ora10g' only location (10g installation location).

  But the tnsnames I mentioned in the file are not getting identified. I get the error message "TNS could not resolve service name".

  And if I replace the tnsname for (for example: UAT) with UAT.world, and then its getting identified. Which means that I realized that this format is to check with the Oracle8 version. There is no problem with format tns.

  Now my question is what are the settings that should be changed to make this file be scanned with the installation of Oracle 10 g.

  Please help me...

  But if you have, as you say, two ORACLE_HOMES, you need to make the change in the relevent one.  Better to do that sybrand said and set your TNS_ADMIN variable to point to one or the other.  Indeed, in such a case, I would say for the creation of a special "tns admin" directory.  Say, "C:\app\oracle\tnsadmin\."  Place your files tnsnames.ora or sqlnet.ora in this directory and set 'TNS_ADMIN = C:\app\oracle\tnsadmin'

• Issue of INS-35354 when installing Oracle RAC 12 on infrastructure Oracle Grid 12

  Hello

  I am trying to install Oracle RAC 12.1.0.2 one node installation on Windows Server R2 2012, but the installer told me:

  'Valid [INS-35354] the system on which you try to install Oracle RAC One doesn't not part of a cluster.'

  On the same server I have is installed and running Oracle Grid Infrastructure + ASM.

  I don't know what is missing the installation program, which is possible to register? The installation program does not provide which had not passed the specific audit.

  Thanks for the tips

  Georg

  

  

  

  Hello

  A CCR node does not mean that you install the grid infrastructure in a single node and install a base of a RAC data on this node.

  Basically, a concept CAR is similar to active passive clustering to provide high availability. To have a node database RAC upward and launched, you will have to install clusterware on at least two server by selecting the option during the installation of the IM.

  Pls follow the below post for detailed answer

• When I need the machine tnsnames.ora and customer configurations?

  Hello
  
  I installed Oracle 11 g on Linux system and successfully created the databases. I can access the database (on server) Enterprise Manager and SQL * (by sqlplus SYSTEM/pass@ora). On another computer I installed the Oracle 11 g database Client (and chose the type administrator installation). Before you start the network for local configuration Setup Wizard Net Service Name, I started Enterprise Manager (the same address, what happens on the server). I was very surprised that I can access Enterprise Manager client without any additional configuration.
  I know, tnsnames.ora help with SQL * more (we can access SYSTEM/pass@ora and don't give no address ip and port).
  And my questions: can I access by Enterprise Manager of any client computer without creating tnsnames.ora and additional configurations client machine?
  Is SQL * more use only tnsnames.ora?
  
  Thanks awfully for help.

  Yes, because the Business Manager is an application of 3 layers: you connect to an application server that connects to the database instance.

  Luk004 wrote:
  Is SQL * more use only tnsnames.ora?

  No.: each client must connect directly to the instance of database with a base layer Oracle Call Interface (OCI) must use tnsnames.ora.
  There are a few exceptions:

• Net Oracle does not read the tnsnames.ora file.

  I am running 11.2.0.3 on Solaris 10 SPARC x 64. I'm trying to configure oracle net for a new database on hold in order to be able to use rman duplicate to create. LDAP is what we mainly use for all of our connections and, possibly, what I could use very well for my goal of rman duplication. But, I fear that I do nothing seems to allow me to read the tnsnames.ora file.

  My SQLNET. ORA file is as follows:

  NAMES. DIRECTORY_PATH = (LDAP, TNSNAMES)

  My TNSNAMES file. ORA file is as follows on both servers:

  (ADDRESS = (PROTOCOL = TCP)(HOST = standby_server) (PORT = 1521))
  )
  (CONNECT_DATA = (SERVICE_NAME = wldb_there.mydomain.com))

  I have a static entry in the remote listener.ora file so I can connect to create the instance:

  Because you have NAMES. DEFAULT_DOMAIN = mydomain.com in your sqlnet.ora, when you try to connect to "WLDB_HERE", before tnsnames.ora is read, sqlnet will transform your application in "WLDB_HERE.mydomain.com".  And that's what he's going to get.

• Oracle apex 5.0: not update the values in the Collection.

  Hello again,

  I have a problem in IR where content comes from the collection query.

  Now the question is when I update the value of the column in the report and click on the custom button, that it will update the value of collection and insert the updated values of the collection member in another table that works well according to my condition, but when I will apply to any word in the search bar (say books in order not to update the values of books) and tries to update the value as a result of research above requirement does not work I mean the collection is not updated. Apex. Oracle.com

  testdump/developer/Office

  All of the Suggestions!

  Thank you

  The "coll update" process fails with a ORA-01403: no data found error. This happens in line 11 because of the access attempt to the wwv_flow.g_f01 using the variable array subscript c who has been incremented beyond the size of the table, which is now smaller because of the IR filter applied.

  begin declare
    c pls_integer := 0;
  begin
  for c1 in (
    select seq_id,c001 from apex_collections
    where collection_name = 'MATRIX2'
    ) loop
  c:=c+1;
  apex_debug.message(c);
    apex_collection.update_member_attribute (p_collection_name=> 'MATRIX2',
    p_seq=> c1.seq_id,p_attr_number =>'2',p_attr_value=>wwv_flow.g_f01(c));
  
  end loop;
  end;
  end;
  

  I agree with fondant tabular forms on interactive reports, but you can meet your requirement as follows. In your application, see page 2.

  1 Add a column of form element hidden IR containing the sequence number of collection:

  select
      c001 col1
    , apex_item.text(2, c002) col2
    , apex_item.hidden(1, seq_id) seq
  from
      apex_collections
  where
      collection_name = 'MATRIX2'
  

  2 place the question of the hidden form in the report using the COL1 Expression HTML attribute:

  #COL1##SEQ#
  

  3. change submit to the process if it is driven by the subject table, not the existing collection:

  begin
  
    for i in 1..apex_application.g_f01.count
    loop
      apex_collection.update_member_attribute(
          p_collection_name=> 'MATRIX2'
        , p_seq=> apex_application.g_f01(i)
        , p_attr_number => '2'
        , p_attr_value=> apex_application.g_f02(i));
    end loop;
  
  end;

  Someone at - he encounter the same problem with 12.1.0.2 by deploying the CDB for Grid Infrastructure Management repository? Is there something special with UEK3 (3.8.13 - 35.3.4.el7uek) on 7 OEL? Any necessary special kernel parameter (although the runInstaller controls do not mention)? I'm totally tapped by GI 12.1.0.2.

  Thank you.

  Hi guys,.

  I was finally able to solve this problem.

  She was related to a memory on the provisioning of problem in the virtual environment as both nodes are VMs. Unfortunately none of these errors of memory were populated / pushed somehow in the virtual machine.

  Your paging file must be at least as big as your physical ram, or in your case specific at least 9 GB or larger.  The value of your swap 32 GB if you plan to use the AMM but I wouldn't use it AMM because Oracle does not support on Solaris.  Supported only for the ASM instance and not the databases.

• EM does not create entry tnsnames.ora with service name orcl11gr2

  Hi all
  
  I am trying to create a service network with EM Database Control, Net Services Administration link name. On the service name field, under the "Edit Net Service Name" screen, I type in orcl11gr2, and it throws the following error:
  
  Validation error
  Review and correct the following errors, and then try again:
  Service name - specify a valid service name.
  
  I wonder what is the additional validation that checks EM. I guess it's to check the number of characters to 8 characters or less.
  
  In addition, because of this additional validation that is in MS, all entry tnsnames.ora with service name = orcl11gr2, I won't be able to use 'EM to change, as I have the same error.
  
  But why Oracle implements this additional validation when the same validation is not implemented on other Oracle tools? For example:
  1 dbca allows me to create a database with instance_name greater than 8 characters, and the results of the initialization parameters will be as follows:
  db_name = orcl11gr - truncated to 8 characters
  instance_name = orcl11gr2
  db_unique_name = orcl11gr2
  noms_service = orcl11gr2
  
  2 oracle Net Manager supports the name of orcl11gr2. The name of the created Service Net, I have no problem connecting to the database.
  3. name of the service orcl11gr2 of listener support
  
  I am using Oracle 11 g R2 (11.2.0.1.0) for Microsoft Windows (x 64), running on Windows 7.

  Its a known issue fixed 12gc Ms.

• tnsnames.ora and oracle cleint

  We have a duty to make an analysis of data on one of our oracle databases. We have a copy of the tnsnames.ora file with the Server DB and SID etc.
  
  If you use something like toad or gold to query the DB, you also need to install client oracle on the machine (windows XP)? Or just the TOAD software?
  
  Is there a device by default on XP where tnsnames.ora needs to be saved?
  
  And if we don't need the customer what is the right version?

  Toad, Yes, you have the Oracle client. Cannot say on 'gold', I don't know what it is. In general, any product like that will sit on top the Oracle client, not replace it.

  There is nothing magical about tnsnames.ora. It is just a file of name resolution that is used by the software oracle client. If you have a magical application which replaces the customer oracle instead of using it, then your tnsnames.ora will be without intrinsic value beyond giving you the necessary information configure magic of the application.

• Sqlplus not find tnsnames.ora

  Hey guys,.
  
  I have a question about oracle client and the tnsnames.ora file. Basically, I have the customer put in place and it seems to work on the use of sqldeveloper such that she can see the tnsnames.ora file in the drop-down list but I don't seem to be able to connect using sql, which makes me think that it cannot find the file ora. I set the env as:
  

  DON@donkeyhome:/usr/lib/oracle$ echo $PATH
  .:/usr/lib/oracle/oracle_client/bin:.:/usr/lib/jvm/jdk/bin:/usr/lib/jvm/jdk/jre/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
  DON@donkeyhome:/usr/lib/oracle$ echo $ORACLE_HOME
  /usr/lib/oracle/oracle_client
  DON@donkeyhome:/usr/lib/oracle$ echo $TNS_ADMIN
  /usr/lib/oracle/network/admin
  DON@donkeyhome:/usr/lib/oracle$

  Sql developer seems to work with the tns ok but not sqlplus:
  
  

  DON@donkeyhome:/usr/lib/oracle$ sqlplus SYSADM@STUDA1

  Any help with this would be greatly appreciated that I had this problem and commented on many forums for about 1 month now :(

  Wheelie,

  I understand that you have tried many options to solve and in general, this mistake is easy to correct. Bad especially as a tnsnames.ora entry, you can also try dos2unix tnsnames.ora see if it removes all special characters and it changes size.
