• Do not get the jdbc connection error

  Hi all
  I use ODI 11.6 and Oracle 11 g.
  I'm currently checking functionality of commit / rollback senario ODI.
  But I get the error in my procedure where I wrote a simple Jython script in command on source below RAISE EXCEPTION ("\N \N \N IS TOTAL COUNT: #COUNT\N \N \N")
  
  We need to write a Jython script for this check counting this is required to verify whether or not the validation works.
  
  Issue in this approach:
  
  I'm trying this way but has detected an error, don't know why its do not receive the jdbc connection.

• ADF: Management graciously JDBC connection errors?

  Hi gang
  
  We have a use case view a specific web page when the JDBC connection falls on our ADF application, specifically the following error:
  
  oracle.jbo.DMLException: Houston-26061: error when opening JDBC connection.
  
  I did research on solutions to this and came up with a solution of proximity to place the following entry in the application's web.xml file:

  <error-page>
    <exception-type>oracle.jbo.DMLException</exception-type>
    <location>/MyErrorPage.jsp</location>
  </error-page>

  This works very well, but is a blunt mechanism because it captures all the DMLExceptions which includes failures of insert/update / delete, as well as the fall of JDBC connection on the.
  
  Everybody comes back with a better solution for the treatment of the JDBC connection drop-outs?
  
  Thank you and best regards,
  
  CM.

  Hi Chris,

  Caveat: I've not tested this - just think aloud at this stage before my departure to catch a train...

  Could you do that in a custom class of DCErrorHandlerImpl? I don't know if you are authorized to make a redirect in reportException or not - I'll have to try that.

• AWM 11 g - the second DataProvider initialization error on a JDBC connection

  Hello
  
  determination of 11g AW in Database 11.2.0.2 with AWM 11.2.0.2.0A fails with the error message:
  
  INI: error opening connection, generic for TxsOqServer::connectINI: error of initialization of the second DataProvider on a JDBC connection, generic TxsOqConnection::initialize
  
  An error occurred on the server
  Class of error: OLAPI
  Server error descriptions:
  INI: error opening connection, generic for TxsOqServer::connect
  INI: error on a JDBC connection, generic DataProvider initialization in TxsOqConnection::initialize second
  
  Connection to the database itself works fine, only attach AW gives the error.
  There is no other connection or session of AW present.
  Until yesterday, it was fine and now it has stopped working suddenly.
  
  Client:
  AWM 11.2.0.2.0A
  Windows 7 64 bit
  Java 1.6.0_22
  
  Any ideas?
  
  Thank you and best regards,
  Silvio.

  I just confirmed against a 11.2.0.3.0 version of MN and
  11.2.0.3.0 RDBMS, there is a bug in AWM.
  I've found a workaround until the bug can be fixed in the next
  patch. I tested the workaound and it does not work properly.

  Workaround solution:
  When you open a session in AWM and connect to your database, please
  attach an analytic workspace that doesn't have data security.
  This will initialize the data provider of the server for you session or connection.
  After that, you can connect an analytic workspace that has safely
  data security and do not get the error you have seen.

  Note:
  The bug is the combination with the security of the data AND using the custom
  AWM. Properties setting _aw.model.show.attach = y. The bug is not
  happen if you choose to define _aw.model.show.attach = n or use the parameter
  off by default quite properly awm.properties automatically set the
  analytic workspace in rw mode.
  I'll fill a bug for this report and see it being solved in the next series of patch.
  Thank you for your patience and the bug report.

• Follow incoming JDBC connections to the database server

  Hello
  
  We have a database of 10gr 2 on RHEL4. This database is mainly used by Oracle E-Business suite.
  External applications connect to the database using JDBC. Most of the time this configuration works very well. Sometimes, however, we get an error "no data to read from socket" at the end of the external applications. It seems to be a problem with the JDBC connections, but we could not even identify him. But I feel that the problem is NOT the end of the database. I just want to confirm that.
  
  To cut a long story short - is it possible to follow incoming JDBC connections on the database server? Of course, I can follow the actual sessions created for external applications. But is it possible that I can say that if the JDBC request reached the server database or not?

  As the JDBC connection string is correct at the client end, I'll be able to find details of all applications for connection in the newspaper of the listener, even if some of them do not end up like connections to the database.

  Each connection request that gets the listener is registered; regardless of the success or failure.
  listener registers status = 0 for successful queries.
  listener registered status = (as 12514) for failed requests
  If/when the connection request goes wrong & can't seem to the listener, then the listener does nothing;
  Since he never received such a request

• CF10 MS SQL JDBC connection

  Hello

  I can't do with MS SQL 2008 Express Edition and CF10 JDBC connection. CF MS SQL Server driver works fine. I use this string to connect

  JDBC:SQLServer://127.0.0.1/myinstance:12345; databaseName = name of the database, but get the error this server is not available. I tried MS JDBC driver v3 and v4, but with the same result.

  May be using MS SQL Server driver is fine, but I had some problems with it on CF8 and CF9, as he said that this request was not exist. So, I had to use the JDBC driver. Maybe it's fixed in CF10. We will see soon, if I do not solve the above problem.

  Thank you

  Beware of drive. Why use Java 7? I had that Java already installed and it was easy for me to sweep CF10 above and use it. Adobe CF does not support Java 7, but it may make more sense to use Java 6 (1.6.0_35?) tho also keep in mind CF Adobe do not officially support beyond 1.6.0_29.

  Sudhakar salvation, you must use the exact client version when possible; your JDBC driver problem is not related to the version of the client...

  The customer is not used by the components Web J2EE for example the Foundation Web Services (Shared Services), RA Framework Web (Workspace), EPMA Web, financial reports, Web planning, Web...

  If you use these components, it is used by the part IIS of EPMA, HFM and FDM.

  Your DBA confirm that you use indeed to connect the correct listening port? If the telnet test works you will see it go with a blinking cursor. When it fails, you receive the message: "could not open connection to the host, on port: XXXX...". ».

  Designated operational entities the above exception occurs when the database is unavailable and weblogic attempts to create the connection to the database using the file descriptors in turn that is causing the files too many error messages.
  
  Please feel free to correct me.
  
  Thanmks in advance :)

  It occurs when the database is completely down.
  But it could happen if the database is blocked and you try to create a large number of connections.
  Watch this forum for more information on too many files open.

  Hi Ed

  As Carsten mentions his new and also more than simple JDBC, mapping can be set up and out of the box or customized models code assigned to the execution units. This allows you to have the use of two models of code based on the standards or in bulk models style movement data.

  There are a few messages from Mark Rittman on SQL Server using these mappings in GR 11, 2 here:

• Taking JDBC connection configuration supported the RAC in Oracle SQL Developer?

  How can one Oracle SQL Developer be configured to successfully connect to a [Oracle RAC | http://en.wikipedia.org/wiki/Oracle_RAC] environment, that is, not only the installation program always to connect to one of the individual nodes?
  
  [http://programmersjournal.blogspot.com/2008/08/jdbc-connection-string-for-oracle-rac.html] is an example of a classic and taking version supported the equivalent CARS of a JDBC connection string. I've used a CAR of the same format connection string from within Java applications custom without problem. I thought that the same thing should be configurable in Oracle SQL Developer, by setting the 'Connection Type' drop-down menu on "Advanced", then enter the connection string JDBC RAC-aware as "Custom URL JDBC". However, after the test connection, the following error message is displayed at the bottom of the dialog box:
  
  Status: Failure-Test failed: IO exception: NL Exception has been generated
  
  There is no additional information shown on the display 'Page Logging'. With the help of Oracle SQL Developer 1.5.5.
  
  Thank you!

  You could always give the current 2.1 ai2 test... continuous development may have fixed the issues in this area...

• Update the Adobe Flash plugin always translates into a connection error

  Firefox quote plugin Adobe Flash as being outdated (has happened several times previously); the latest version of the plugin is downloaded (as done successfully many times before). This time, a connection error occurs. Repeat the process several times over several days gives the same results.

  More in detail, the smallest prior download EXE which is first downloaded from the Adobe site is able to be downloaded, but by operating it said something like "Download will begin shortly," with the download of the application itself never occurring, and a later message connection error.

  Although there seems to be a problem with Adobe, I suppose that other Firefox users would have also encountered this problem and he may know a solution.

  Better to use the full installer offline from here:
  https://www.Adobe.com/products/flashplayer/distribution3.html

• I get a 'Secure connection' error failed with google stating "certificate contains the same serial number.

  When I click on a link to a google search, I get the "Secure connection" error failed in Firefox. He says, "please contact the administrator of the server or email correspondent and give them the following information: your certificate contains the same serial number for another certificate issued by the certification authority."

  I followed the instructions here:

  and looked at this article:
  https://support.Mozilla.org/en-us/questions/1028103?ESAB=a & As = AAQ

  I uninstalled and reinstalled Firefox, deleted the entire folder profiles and reset Firefox. I see that the older (orphans) article points to my router. However, I have a new router and have updated their software. There is no button to add an exception (as stated in the article), so I can't just work around it. This problem does not occur with IE, so I have a hard time to believe that it is my router.

  How to solve this problem? I really want to change browser.

  Finally, I tracked the issue. The answer was found here:
  https://support.Mozilla.org/en-us/questions/1028985

  It turns out that Avast has a web shield that passes through its own verification of certificate https. Of course, this feature is not quite right and loses track of the certificates. Disable "https scanning" in the settings of Avast resolved the problem.
