• 4EA2: oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber () I supplier code 0

  Hi people, when I tried to connect to an Oracle 11g server, I came across this error:

  "An error occurred to perform the requested operation."

  oracle.jdbc.driver.T2CConnection.getLibraryVersionNumber () IVendor code 0

  "
  

  As I Googled it, the reason was this setting:

  tools::preferences:database: Advanced: use driver OIC/thickness = true

  Customer tested versions: 12.1.0.1.0, 11.2.0.1.0 (bth client versions raises using the same error)

  Solution: put tools::preferences:database: Advanced: use driver OIC/thickness false

  Is this a bug or a feature? In previous versions (3.xxxx), it worked perfectly, but I found some messages describing this error with the first versions of the adopter of the 3.xxxx.

  Thanks for all the relevant answers :-)

  This is a feature.   The version of the Oracle client must always match the JDBC version using SQL Developer.

  that is if the SQL Developer runs 11.2.0.3 JDBC, then your oracle client must be 11.2.0.3.

  Unfortunately, it is not always clear what version of JDBC SQL Developer is provided with.

  There are a number of solutions, you can search the forum. He's probably using the driver not supported 10g.
  Make sure you have preferences - Database - advanced - use OIC/thickness uncontrolled pilot and maybe use basic connections rather TNS. You can also install the 11.2 customer or change your ORACLE_HOME.

  MSR

  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.

  Hello

  Rather than use startWeblogic.cmd, I suggest using the setDomainEnv.cmd file so that the property can be set to the FQDN.

  use the value to the setDomainEnv.cmd file below:
  Set JAVA_PROPERTIES =-Duser.timezone = "+ 05:30 ' % JAVA_PROPERTIES % EXTRA_JAVA_PROPERTIES %

  Use of the "" use your DB to the value of the time zone.

  Thank you

  Hi Nils

  12.1.3 WebLogic jdbc libraries are located in the MW_HOME/oracle_common/modules/oracle.jdbc_12.1.0 directory level.

  For this WLS jdbc driver is ojdbc7.jar which is loaded on startup of WLS.

  As mentioned on the post preceding this is is not compatible with the 11.1.1.7.3 MapViewer to display the ORDIMAGE. Seems that even the ojdbc6.jar that exists in this directory cannot be used.

  What to do is make the WLS Server uses the ojdbc6.jar for 11.1.1.7.3. There are different ways to use a different pot in WebLogic.

  This page http://docs.oracle.com/middleware/1212/wls/JDBCA/third_party_drivers.htm was noted in this regard.

  As a quick test, you can try to make the ORDIMAGE with the following steps;

  (1) on page MapViewer OTN, Oracle Fusion Middleware MapViewer access downloads and download the quick start for the 11.1.1.7.3 Version.

  You will find the glassfish3/glassfish/domains/Domain1/lib folder a file jdbc ojdbc6.jar.

  (2) on your installation of a WebLogic domain:

  Navigate to the oracle_common/modules/oracle.jdbc_12.1.0 directory

  make a backup of ojdbc7.jar

  copy the ojdbc6.jar on top of ojdbc7.jar

  (3) start Weblogic server and try to make your theme ORDIMAGE.

  As I mentioned before, there are different ways to add a jar to WebLogic classpath. The quick test above is just replace the original ojdbc7.jar in a facility that is not good, as you lose you original ojdbc7.jar.

  Best regards.

• How to avoid using oracle.jdbc.driver.OracleConnection

  I am new to Java, but recently, I have a project on support.

  Problem:

  solution worked on the 1.4 jvm, now on 1.7.

  Respectively, the oracle.jdbc.driver.OracleConnection class has been used.

  Now, I need class oracle.jdbc.OracleConnection to use CLOB.createTemporary (), but... I can't.

  According to the docs, just replace in the code and config files a declaration of the class on another. But I replaced all in all the files of configuration of no. and anyway, no there wasn't that oracle.jdbc.driver.OracleConnection was created. (there is no explicit declaration of the type of connection in the code, everything is configured in the config files)

  Project uses marven, mybatis - 3.1.1. Database: oracle 9

  Driver: ojdbc14 - 9.2.0.5.jar contains two classes: the oracle.jdbc.driver.OracleConnection (for backward compatibility) and oracle.jdbc.OracleConnection.

  The question is what do I need to use a second instead of the first.

  Maybe there are a few java cache? I do not know...

  Everyone knows?

  I solved the problem!

  This thread helped me: https://forums.oracle.com/thread/556426 ("I have to use classes12.zip for this work.")

  The main problem was the jdbc driver - I tried all the ones I found on the page of download of oracle and the only factor that does the job was classes12.jar (Oracle Database 10g Release 2 (10.2.0.1.0)). I replaced it in 'ORACLE_HOME\jdbc\lib\' and 'apache-tomcat\lib\.

  Each driver has its own bugs, and I also did different things, so I can't say that any replacement driver is enough. Te I changed the time zone database, run the tzupdater, vm set param - Duser.timezone = ""-07:00 ", may be something else."

  Thank you very much for the answer so detailed!

• 125, hogging threads waiting for lock oracle.jdbc.driver.T4CConnection@5500

  We use DBAdapter in soa suite 11 g (xa thin drivers, AIX platform) to talk to the database. At one point today, we could see the system WLS slows down considerably and thread dumps could see 125 hogging son everyone waits for the next lock:
  
  ' ExecuteThread: '16' for queue: '(self-adjusting) weblogic.kernel.Default' "waiting for lock *oracle.jdbc.driver.T4CConnection@55005500* BLOCKED

  weblogic.jdbc.wrapper.VendorXAResource.rollback(VendorXAResource.java:78)
  weblogic.jdbc.jta.DataSource.rollback(DataSource.java:1146)
  
  Can someone point to this oracle.jdbc.driver.T4CConnection@55005500. Is that a lock on a connection object? If so this means that all 125 discussions were waiting for a single connection? The source of data used has default settings for the connection pool.
  
  I couldn't see any thread thread discharge which States that it is now the same lock, possibly could be a problem with the way thread dump is generated in AIX
  
  Can someone shed some light on this?

  Hello. Grep just for T4CConnection@55005500 in the discharge. You will see the number of threads
  blocked (as you would expect) on this point, but only one thread that already have this object
  locked and uses it. Unfortunately, the thread is suspended in a call to DBMS, so it cannot
  go ahead and release the connection object and let all other threads proceed.
  I has you pointed out only one thread.

• The package level logging to the Oracle JDBC driver?

  With JDK Logging (java.util.logging) I was not able to open a session active newspapers at the class level. It was only possible to activate the logs for a particular java package.
  For example to enable the logs from the oracle.jdbc.pool.OracleDataSource of the class in the oracle jdbc driver, must be added below the line in the logging.properties file.
  

   oracle.jdbc.pool.level = FINE 

  You couldn't do
  

   oracle.jdbc.pool.OracleDataSource.level = FINE 

  Am I missing something? If it is not possible to activate the logging of class level, can someone indicate the reason behind not able to do so or why java.util.logging does not allow this?

  This isn't for lack of java.util.logging. It's because that's how Oracle chose to implement logging in the package oracle.jdbc.pool, i.e. at the level of the package name. Java.util.Logging can go as thin as you like, depending on what names pass you to Logger.getLogger ().

• 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?
  
  
  Kind regards

  Oracle RDBMS cannot differentiate between connection OPTION of any other flavor of the customer.

  Knew that :)

  listener registers EACH connection request, you get

  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.

  PS: I do not belong to the sanctified tribu tribe of DBAs, so please excuse the obvious ignorance!

  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
