• Solaris PHP 5.2.12 Oracle Instant Client error

  We test an Oracle Solaris 11 Express Server with the standard installation of Apache and PHP. But we have the Oracle Instant client and module oci8 enabled for applications of our society.
  
  We did it using the. / pecl install oci8 in usr/php/5.2/bin. We set the LD_LIBRARY_PATH in /etc/apache2/2.2/envvars
  
  version 32 bit for solaris (x 86) of the Oracle Instant Client 11.2 is installed in/opt/oracle/instantclient_11_2 with the symbolic link.
  
  envvars:
  LD_LIBRARY_PATH = / opt/oracle/instantclient_11_2
  ORACLE_HOME = / opt/oracle/instantclient_11_2
  ORACLE_BASE = / opt/oracle/instantclient_11_2
  
  PHP and the oci8 module set the charge.
  
  phpinfo(); output:

  When we discover everything first a site there is no problem but very random, we get the following error:
  
  OCIEnvNlsCreate() failed. There is a problem with your system - please check LD_LIBRARY_PATH includes the directory with Oracle Instant Client libraries*.
  
  but when we use echo getenv ("LD_LIBRARY_PATH"); in php, the output is "/ opt/oracle/instantclient_11_2.
  
  now, the strange, that it's as random as it appears he disappears we can load the web page without a problem and after a few clicks of the error is back. If we wait for a cup of seconds you can reload the page and it loads normally.
  The error seems to be random and we get it over and over again, it comes and goes after a cpl of pages are read. It seems to appear more when there are multiple users browsing the Web site.
  
  Is there any solution for this? is this a known bug? It seems strange that the instant client works sometimes and fails a second later without a change in the system.
  Hope someone can help us.

  A few tips on how to solve this problem would be greatly appreciated.
  
  Thanks in advance

  This error seems to confirm my suspicions, it is due to the fact that main.o (and perhaps someDotOFile.o too) have been compiled for 32-bit.

  You must also add - maix64 when you compile the two objects in source files.

  I mean, I am not sure that the bit incompatibility really is the problem here, but it would at least explain why the linker can't find these symbols in libclntsh.a.

  I guess you made sure that libclntsh.a is in/oracle/instantclient_10.2, right?

• not able to connect to the database using the oracle instant client

  Hello
  
  I am not able to connect to the database using the instant oracle from my local PC client. They use to connect to the database files and sqlnet.ora files LDAP.ora. If I want to test the connection, I found this executable tns wasn't there, so not able to tnsping. So I'm not able to solve this problem.
  
  Please let me know if a solution for everything
  
  Client Oracle: oracle 10.2bFAT client 32-bit
  
  Platform: windows 7 64-bit
  
  Thank you
  Veera

  There is little that tnsping can do sqlplus can't.

  Instead of
  tnsping mydb.myorg.com
  Try
  sqlplus-s-L /@mydb.myorg.com
  or
  sqlplus-s-L user/[email protected]

  If you get
  ORA-12154: TNS: could not resolve the connect identifier specified
  you know that the customer could not resolve 'mydb.myorg.com '.

  If you get
  ORA-12541: TNS:no listener
  then "mydb.myorg.com" could be resolved, but there is no listener it running.

  If you get
  ORA-12514: TNS:listener is not currently of service requested in connect descriptor
  then "mydb.myorg.com" could be solved, the listener is in place, and the database is out of service.

  If you get
  ORA-01017: name of user and password invalid. connection refused
  you know that 'mydb.myorg.com' has been successfully resolved, and the database is running.

  If you want more details, such as how and what "mydb.myorg.com" is resolved, turn the tracking by adding the following to "sqlnet.ora:
  TRACE_LEVEL_CLIENT = ADMIN
  TRACE_DIRECTORY_CLIENT = C:\TEMP (a writable directory)

  Then you will find lines like this in the trace file:

  -THE INFORMATION SOURCE PARAMETER FOLLOWS-
  Attempt to load system pfile source C:\oracle\network\admin\sqlnet.ora
  Source of the setting successfully loaded

  Attempt to load the local pfile source C:\Dokumente und Einstellungen\lanadvall\sqlnet.ora
  The parameter source has not been loaded.

  This shows you which configuration files are read, followed by the settings real read.

• SQL Loader for Oracle instant client 11

  I have a problem sqlldr.exe running on a machine having Oralce 11.1.0.6 instant client installed. I already copied all the DLL files it says that he needs and the whole repertoire of a machine with installation complete of RDBMS. This is the error I get:
  
  + SQL * Loader-704: Internal error: ulconnect: OCIEnvCreate [-1] +.
  
  I have no problem to connect what either using sqldeveloper. Are there files or the steps I'm missing?
  
  Thank you
  -Chris

  The add-on only supported for the moment customer is sqlplus, integration of other utilities is not supported. You can just mix DLLs of different software. There are a few documents on workarounds, for example:

  http://www.nyoug.org/presentations/2007/200703_Ji_Instant%20Client.PDF

  But no guarantee that it works and not support of Oracle.

• Using the Instant Client via OIC

  Hello world
  
  A developer says he has problem to connect to Oracle and I asked how do you connect from his pc. He said that it is "use Instant Client via OIC."
  
  Is this the normal stuff like Oracle_sid, tnsnames and sqlnet in the pc of the client or something more than that?
  
  Please enlighten me on this.
  
  Thank you.

  OIC is the Oracle Call Interface and Instant Client implements this API.

  There is a large painting of OIC and how it fits into the pile of products [url http://download.oracle.com/docs/cd/E11882_01/server.112/e10729/ch7progrunicode.htm#i1005974] Oracle database access.

  Your application can be OIC based, as is the Sql * plus, .net Data provider, thick driver JDBC, etc. etc. (read the description following the figure for more examples).

• Instant Client connection problem - Excel 2007 for Oracle 10 g

  Dear users,
  
  I want help to connect Excel to Oracle.
  I use Excel 2007 (32-bit) on Windows Vista Enterprise 64-bit. I want to connect to a database 10g to Oracle through our local network using ODBC. I need to retrieve data once in an excel sheet.
  There is no firewall or connection between my current computer problems, problems as I can connect to my machine, using SQL developer as a local client to the Oracle database that is located on another machine on the network.
  I tried to make an ODBC connection, but Oracle is not listed as a driver.
  In my view, what ODBC is the best way to do it, but please correct me if I'm wrong.
  
  It is an Oracle 10 G database.
  I downloaded instantclient-basiclite - 64 - 11.2.0.2.0.zip a windows.x
  I also downloaded the additional ODBC components: * Instant Client Package - ODBC: extra to allow ODBC applications libraries.
  
  I unzipped in a folder called C:\instantclient_11_2
  The system path include one. I checked after reboot.
  I placed my tnsnames.ora (that I copied from the server) in this folder.
  I got it from the server: D:\Oracle\Ora10gR2DB\network\admin\tnsnames.ora
  
  I ran the exe "odbc_install" and he told me that the ODBC has been successfully intalled.
  
  When I went to the Control Panel, administrative tools, ODBC
  
  On the user dsn tab
  
  I added a new entry. I chose the Oracle driver (previously it was not in the list)
  
  Use the following values
  
  Data Source name: OracleL
  123 description
  The TNS Service name: I chose for my prod environment drop-down list. (There are two entrances with the name of the production, one uppercase and one lowercase)
  
  
  UserID: my user name
  
  I tried the connection Test and got this:
  
  Unable to connect
  
  SQlState = S1000
  [Oracle] [ODBC] [Ora] ORA-12545: Connect failed because target host or object does not exist
  
  
  Any suggestions please.
  
  Thnaks in advance.

  If Excel is 32-bit (2007a) and the Oracle client libraries are 64-bit, it will not work. needs 32-bit 32-bit.
  You should probably remove current ic packages and get the 32-bit instead.
  Start over.

  On Windows x 64, to run the 32 - bit ODBC DSN/drivers, we need run the Windows\SysWoW64\odbcad32.exe tool.

• error in a WPF application using oracle.manageddataaccess.client

  Hello

  We have problems with a WPF MVVM using Oracle.ManagedDataAccess.Client application. We installed oracle.manageddataaccess.dll release 12.1.0.1.0 on a developer machine with 64 bit of Windows 7, Microsoft Visual Studio 2013 and Microsoft .NET Framework 4 OS. Installation seems to be ok and oracle.manageddataaccess.dll results to be registered in .net\assembly\GAC_MSIL c:\windows\microsoft. But when we try to compile the application, the following errors occurs

  Error 175: The ADO.NET provider with invariant name 'Oracle.ManagedDataAccess.Client' not is either not saved in the config machine or the application of the file, or could not be loaded

  errors are caused by the entity data model files (there is an error for each .edmx file).

  Note that the application works on another computer with the same configuration, so I guess that the problem is due to a bad setting on the computer

  any idea?

  Hello

  Finally, we have solved the problem! simply, we uninstalled and reinstalled Visual Studio and Oracle.manageddataaccess in this order. Now it's working. Thank you

  Alex,

  Finally, we have solved the problem.  It turns out that we had a bad x 64 home path in the PATH variable.  I lost track of what it was originally, but I'm sure the x 64 bin path was correct. I did not notice that it was wrong, until I tried to install the full client and began to see an error indicating that it was missing a dll.  This led me to a post on the forum, in which you indicated that the PATH variable has not been set (ODAC 12 c for xcopy issues).  In our case, it is not missing, just fake.

  This is the behavior that we see if the PATH variable for the home directories and bin is incorrect:

  • Full client: an error of external system (no exceptions).  The error message is that the oraons.dll is missing.
  • XCOPY customer: generates an exception without error message.  The Exception.Message property is empty and there is no inner exception.

  Can the ODP team can add a meaningful message for this exception?  If the exact error cannot be highlighted during execution, a generic name on the path audit would help enormously.  I must have looked at it a dozen times and didn't notice that it was false.  If I had no idea that this could be the cause, it would be discussed more in detail, or had someone else Verify that it was correct.  I hope that we would have solved much earlier.

  Thank you.

• Oracle.ManagedDataAccess.Client no Oracle client deployment

  Hello

  We are trying to deploy our application on a server that has no Oracle client installed. We use the managed dll dataAccess with entity framework 5. Our web.config file contains the following:

  < connectionStrings >

  < add name = "CroEntities" connection string connectionString="metadata=res://*/CroModel.csdl|res://*/CroModel.ssdl|res://*/CroModel.msl;provider=Oracle.ManagedDataAccess.Client;provider = & quot; DATA SOURCE =oracle; PASSWORD = password; PERSIST SECURITY INFO = True; USER ID = user & quot; "" ProviderName "/ >

  < / dataSources >

  < / version >

  < /Oracle.ManagedDataAccess.Client >

  Oracle.ManagedDataAccess.dll is in our Bin folder.

  At run time, we get the following error: ORA-12541: TNS: no listener.

  The earpiece works very well. My thought is that something is missing in our configuration. When we add some debug information for the value of context. Database.Connection.Database we get empty string that make me think that the information in the configuration file does not in the run-time application.

  Any thought on what might be missed?

  Thank you

  Ken

  The XML tag should be . All lowercase. In your configuration file, you pulled profit some letters in the tag. It's probably why ODP.NET can't read XML.
