• x 64 application entity Framework using Oracle.DataAccess.Client

  I am trying to build a x 64 application Entity Framework using the current Oracle.DataAccess.Client.  I can launch the application as Any CPU and x 86 using the managed provider, but when I compile for x 64, I get the error below when running. If I change the provider to Oracle.ManagedDataAccess.Client it works with x 86 and x 64 compiler.  Unfortunately, we are unable to use the managed provider until the xml is supported.  I have two clients x 86 and x 64 installed.  Any ideas?

  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.

• Test of the E-Business Suite applications using Oracle performance ATS

  Hello
  I'm going to do tests on the E-Business Suite applications using Oracle Application Testing Suite of performance. I used it for the Siebel load earlier tests, but never for E-Business applications. Can someone tell me what specific setting, I need to put in place on the side of the E-Business Application for load tests?
  
  Are there any parameters server side that needs to be changed so that everything is saved in openscript? Please notify
  
  
  
  
  Concerning
  CP

  Hello
  Nothing to do on the side of the EBS.
  Compare to Siebel, load tests using more memory agent, don't expect not to run too SAW with a single agent. So depending on the number max of SAW, you must properly size your CA.
  Linux is a more scalable system to manage the memory usage. (you can not do that with siebel since the lib of correlation must run on windows).
  According to the script (web or forms, mix, short or long), you will be probably limited to 200/300 users per agent.

• 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

  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.

• "404" error when running ADF Applications using Weblogic / OAM / Webtier

  Hi Experts,
  
  Our organization works on the implementation of Weblogic 10.3.5 on HP - UX 11.31 / PA RISC hardware.
  
  All is well enough to work, but we met a particular hurdle and I hope I can get some advice from people here in the forums.
  
  We have virtual hosts within the Weblogic web layer for different areas. We also have Oracle Access Manager configured to protect some web resources (to force the user to authenticate to access the page). Each virtual host is configured to use the https protocol, and we have SSL certificates installed.
  
  The problem arises when trying to deploy an ADF application for weblogic, then run it through one of these virtual servers. We want these applications to use https only. Mod_wl_ohs has also been configured to forward requests to the web layer weblogic.
  
  App deploys fine, and when you try to access the app, we are redirected to a login page by OAM, which is what we want. However, when the application starts to run, it seems that ADF is adding to the URL query parameters, and when he does this, redirecting to https, which causes a 404 error. If you manually add the 's' on the URL, the application loads and works very well.
  
  For example:
  Say the url of our application is
  https://foo.mydomain.com/MyApp/faces/search
  Navigate to this url redirects to the login page. After the connection, we headed over to something like this (the actual settings vary):
  http://foo.mydomain.com/MyApp/faces/search?_afrLoop=7078069345015890 & _afrWindowMode = 0 & _adf. CTRL-State = yvpch8hdh_4
  .. which returns a 404 error.
  If put us the 's' on the url, it works as expected.
  
  Why is this happening? Why is redirect to the login page staying is not in https?
  
  To facilitate debugging, we created a very simple jsp page that was not developed using ADF, and deployed in a similar way, and he remained in https after redirection from the login page.
  
  Is this a specific problem ADF? Is something that needs to be configured in the ear file deployment of JDeveloper?
  
  Any advice would be much appreciated...

• Case study: reorganize an Oracle Forms application using Oracle JDevelope

  After reading http://www.oracle.com/technology/products/jdev/collateral/4gl/papers/redeveloping_forms_in_adf_11g.pdf (case study: reorganize an Oracle Forms application to help)
  Oracle JDeveloper 11 g and 11 g of OracleADF), I noticed that the Total Order field has not migrated to ADF. I want to create a summary based on a column like this field. How can I do?

  I think (without looking at the code.tables) that the order total is the sum of the of the linetotal of elements

  So in the OrdersVO, you should have a transient OrderTotal attribute that is assigned to the groovy expression ItemsVO.sum ("LineTotal").

  The syntax may not be perfect, but it's the essence of what you need.

• Planning an Application using Oracle EPM 11.1.1.1.0

  Hello
  
  I just installed Oracle EPM 11.1.1.0 and I want to create a planning application. Do I still need to have all EMP services running? For some reason, these services are not starting and I wonder if I can still go ahead and create a planning application.
  
  Thanks in advance,
  
  AD

  Hello

  If you create a planning directly through a planning application and not the workspace then the minimum services you have started will be.

  OpenLdap
  Shared services
  Essbase
  Planning
  RMI Registry & EAS (although strictly you might not need them running only to create an application, but it is advisable to make them work)

  Then you can go directly to set up an application via http://: 8300/HyperionPlanning/AppWizard.jsp

• IIS to DSN Oracle using Oracle Instant Client 12.1

  Hello

  I hope someone here can help me, because it turns out to be a real chore.

  I need a web application of .NET in order to connect to an Oracle database.

  I use IIS 7.5 on a Web of Windows 2008R2 server 0 x 64 and ASP.NET framework 4.0

  I know very little about Oracle, I'm afraid (I'm a dedicated man of SQL Server - sorry!), so I duly donwloaded and installed the 12.1 client instant 0 x 64.

  I followed all the instructions, created the environment variables PATH and TNS_ADMIN (located at c:\instantclient_12_1, where are installed the Oracle), I had some problems with a missing 0 x 64 DLL (visual .net distribution mfc100.dll) delivered with the instant client (since this is a production almost Virgin Web server, and I don't want to install anything I don't need) , but I finally managed to make the system ODBC DSN to connect successfully.

  The tnsnames.ora file has been provided by the DBA and is as follows;

  xxx =

  (DESCRIPTION =

  (ADDRESS_LIST =

  (ADDRESS = (PROTOCOL = TCP)(HOST = xx.xx.xx.xx) (PORT = 1521))

  )

  (CONNECT_DATA =

  (SID = xxxx)

  (SERVER = DEDICATED)

  )

  )

  Great, I thought. Now for IIS.

  My IIS connection string is of the form;

  Dim conn As New Odbc.OdbcConnection("DSN=xxx;) UID = xxx; Pwd = xxx; »)

  However, whenever I try to open the said connection, I get the ubiquitous;

  "ERROR [08004] [Oracle] [ODBC] [Ora] ORA-12154: TNS: could not resolve the connection identifier specifiedERROR [IM006] [Microsoft] [ODBC Driver Manager] driver's SQLSetConnectAttr failed.

  After much research, I came to realize that I'm not the only person with the above error. He seems to be everywhere.

  This means that my IIS application is probably not rethink research tnsnames.ora reference?

  OK, I thought, let's add all accounts of IIS to the c:\instantclient_12_1 (read and execute). It's IIS do not have access to the tnsnames.ora file permissions, but still no joy.

  I also tried to set the identity of the application pool to run under a domain with privalidges account additional IIS, but still the same error.

  I tried to play with various permutations of connection string. I tried it;

  Dim conn As New Odbc.OdbcConnection ("Driver = {Oracle in instantclient_12_1}; ("Source = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST=xx.xx.xx.xx) (PORT = 1521))) (CONNECT_DATA = (SID = xxxx) (SERVER = DEDICATED))); uid = xxx; pwd = xxx") data

  and this one...

  Dim conn As New Odbc.OdbcConnection ("Driver = {Oracle in instantclient_12_1}; Data Source = (DESCRIPTION = (ADDRESS = (PROTOCOL = tcp)(HOST=xx.xx.xx.xx) (PORT = 1521)) (CONNECT_DATA = (SERVICE_NAME = xxxx))); uid = xxx; pwd = xxx")

  The two caused a completely different error, but all too ubiquitous, it seems;

  "ERROR [HY000] [Oracle] [ODBC] [Ora] ORA-12560: TNS:protocol adapter interneErreur [IM006] failedERROR SQLSetConnectAttr in the [Microsoft] [ODBC Driver Manager] [HY000] [Oracle] [ODBC driver] [Ora] ORA-12560: TNS:protocol adapter error.

  In order to try the House on it, I tried to write a small VB SCript file to access the DSN using the same connection string, I first tried;

  Set adoConnection = CreateObject ("ADODB. Connection")

  adoConnection.ConnectionString = "DSN = xxx; UID = xxx; Pwd = xxx; »

  It worked a treat, and I was able to connect perfectly. To try to drill down to the problem, I run this file as the domain user, I put IIS to run as, and it worked a treat with IIS authentication information too.

  So I'm at the end of my mind. I don't understand why IIS can simply use the system DSN.

  
  Thanks to everyone in advance for their help. It is much appreciated.

  Ok. I spent some time on this and managed to get to the bottom of all this.

  Here's what the problem was, in the case where everyone faces a similar problem.

  By deliberately that gives a bad name DSN (another mistake) and an incorrect password (resulted in the same error), I was able to determine that the problem is really that the tnsnames.ora file is not get referenced. No traffic left the server at all, and so the password was not relevant.

  Next step was to check that relax TNS_ADMIN variable has been read by IIS.

  I used the command System.Environment.GetEnvironmentVariable ("TNS_ADMIN") to prove it was empty. That explains pretty much everything that. The recently set the environment variable has not been picked up by IIS. It was nothing to do with permissions to the location of the file tnsnames.ora to all. It's a Kipper.

  It would seem that, surprisingly, server restart is necessary for the work process IIS pick up new environment variables. Basically this simple problem cost me a lot of time and bother. NOT BELIEVE messages that say the restart of IIS or the application will pick up any changes to the environment variables - IT WILL NOT.

  There is a problem more annoying, and it's to make sure that you remove the spaces trrailing on behalf of the Service TNS odbc name box, but it was easier to drill down reletatively for, compared to having to restart the production server.

  Thanks ReubenC for your help. I didn't need to go down the road ODP.NET, but thanks for your suggestion. I wish only Oracle would be to write some notes about it, because I'm sure others will hit / have this problem too. It would also be too much to expect Oracle to include all DLLS in the download as well (!)

  In any case, I'm glad I'm on the right track.

• Why Oracle ManagedDataAccess (4.121.1.0) throws a System.FormatException "first chance" exception to the debugger when you use OracleCommand.BindByName (on some machines, but not others)?

  Why Oracle ManagedDataAccess (4.121.1.0) throws a System.FormatException "first chance" exception to the debugger when you use OracleCommand.BindByName (on some machines, but not others)?

  This occurs when calling a ref cursor-returning packaged function stored with OracleCommand.BindByName set to true.

  When BindByName undefined, it works as expected.

  I've only been able to recreate this problem on a machine in my control. This issue has also reported to me by a customer.

  I tried to change the locale of the system of EN - UK EN-US, but I was not aware of any change in behavior.

  Similarly, I've tried explicitly overriding the default locale of the system with the OracleGlobalization parameters, and it also had no effect.

  Please see the example below.

  Thanks a lot to qualify again for me Alex.  I'll try upgrading to the latest version of the provider.

  The difference in behavior between the two hosts was found to be reduced to differences in configuration VS.

  Checking 'Just my code' prevents the first chance thrown in the debugger exception. As in fact, the exception is handled in the provider, it is enough for me.
