• 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

• JDBC connection does not with ORA-12514

  Hi all

  I also have problems with the connection to the DB CARS because the listener does not recognize the name of the service. I read many messages from the forum itself here and elsewhere and I just can't understand it. Everything seems in order, so I'm a little confused as to why it does not work.

  Thus, some specifications: I actually use SAP as advanced application to connect to the DB.

  DB is RAC 11203, two nodes.

  OS: Linux RH6

  Headphones and remote headphones are a race to the top.

  JDBC connection string fails:

  JDBC:Oracle:Thin:@(Description=(Address=(Protocol=TCP)(Host=virtualhost1)(port=1527))(Address=(Protocol=TCP)(Host=virtualhost2)(port=1527)) (CONNECT_DATA = (SERVICE_NAME = MYSERVICENAME. «"" WORLD)))»»»

  I check that the service is available in the cluster:

  ORA. < dbname >. myServiceName.svc online on physicalhostname1

  When I check the status of the listener on node1 he mentions the MYSERVICENAME downstairs so it's here

  [oracle@physicalhost1 bin] $ lsnrctl serv < DBNAME >. WORLD

  That's where. The database is running.

  I am spent days on this and I am unable to understand. I tried to re - register the name of service to SIR with lowercase, uppercase. In fact, when I joined the service I used capital letters, do not know why crsstat it shows always lowercase. Also in sqlplus I see lowercase. I do know that if it's case sensitive at all, but shows the despair that I really tried everything. I think that the fact that I am using SAP is not serious as long as any application - what is uses the thin JDBC connection string.

  Help, please.

  Your JDBC connection string requires a service MYSERVICENAME. WORLD, it should be MYSERVICENAME.

• JDBC connection error

  I am trying to create a DSN in server v11 of ColdFusion Standard using Sybase jConnect 6.05 driver JDBC connection to Sybase SQL AnyWhere 12 Server (running on another server). ColdFusion was installed on a new server (Standard) 2012 Windows and uses IIS 8 to the web server.

  I did everything mentioned on this page (of course, the driver class and other details have been changed) ColdFusion MX: Configure the Sybase jConnect 5.5 driver

  When I try to check the connection in CF administrator, it throws the following error:

  Connection verification failed for data source: ars_jdbc

  java.sql.SQLException: the com.sybase.jdbc3.jdbc.SybDatabaseMetaData.getJDBCMajorVersion () method has not completed and should not be called.

  The root cause was that: java.sql.SQLException: the com.sybase.jdbc3.jdbc.SybDatabaseMetaData.getJDBCMajorVersion () method has not completed and should not be called.

  I know that all the connection parameters are correct because I was able to create a DSN on another instance of CF (CF 9) on the same basis that I am creating a DSN for CF 11. Please guide me in the right direction to solve the problem.

  Thank you.

  Milind

  Carl Von Stetten and Alexandre thanks for your help.

  There, someday I could correct the connection failure. I downloaded the new version of the (7.0.7) JDBC driver and the DSN was able to connect to the database.

• 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.

• New Taskflow-ADF transaction acquires a new JDBC connection?

  Hello
  
  I would like to learn more about ADF Taskflow transaction regarding the JDBC connection.
  
  TF1-(contains) - page1 and call for tf2
  TF2-(contains) - page 2
  
  Page1 - search objects
  Page 2 - edit objects
  
  
  I have two pages in two taskflows, first taskflow doesn't create any transaction but the page1 in tf1 shows a searh for objects screen. I want to use the transaction behavior of ADF TF for tf2 which is called TF1.
  
  My tf2 contains a page to change objects, if I put the new transaction as a transaction of TF for tf2 behavior.
  
  Is it really to acquire a new JDBC connection?
  
  I'm really grateful if anyone can help me with this.
  
  Thank you
  Sunil.

  Simple answer: Yes.

  Long answer:

  Think when you connect to say database using a tool such as SQL Developer, opening of the SQL worksheet. In this SQL one spreadsheet there is only one connection to the supporting db commit / rollback. You can perform multiple DML statements, and then commit or rollback, followed by several DML statements, then commit and rollback. Basically, it's a connection supported a single transaction at a time, with several transactions sequentially one after another. What you cannot do in the single SQL worksheet is to have several operations going at the same time, you need to spawn separate leaves SQL with separate connections.

  Therefore, the concept of a connection and transaction are related 1 to 1. If you say your BTF you want a new transaction, he must take a new connection, to take charge of the transaction. Simple as that.

  At the end of the day, therefore the features planned.

  Now I detect your question, you do not want this behavior, but I don't know if you understand the concept of transactions, you will need to answer with a description of what you want to achieve... However, if you want a new separate transaction for your BTF, it requires a connection.

• 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...

  Hope that helps,

  Hi 1340420,

  You open a session indicates that you are using incompatible binary RPi and ME SDK. Please make sure that you use both of the same version. That is all two 'Early Access 2' or both ' Early Access 2 (developer last build)' (which is currently b54 as you can tell from the file name). These are not cross-compatible you must always use ME SDK and runtime Java ME to exactly the same version

  The journal of the user404 I can't say what the problem is, it looks more like an internal bug but I'm not sure. Indeed, also please doublecheck you have the same version. In the meantime, we will try to study

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

  Hello

  INI: error opening connection, generic for TxsOqServer::connectINI: error of initialization of the second DataProvider on a JDBC connection, generic TxsOqConnection::initialize

  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:

  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.

  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:

• 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,

  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.
