  • Java.lang.StringIndexOutOfBoundsException when trying to create a JDBC pool connection.

    Hi, I get a java.lang.StringIndexOutOfBoundsException when making a JDBC
    pool connection via the console of WLS 7.0. I use SQL Server 2000 in Win2K
    SP2 environment. Exactly the same configuration works perfectly in WinXP
    Pro. Can anyone advise me what might cause this problem? Thanks a lot.

    (it's a waste of cycles).

    show us your pool definitions from the config.xml file. There's
    probably a
    problem
    with the URL or properties.

    The database is oracle 8.1.6 and I am using the thin jdbc driver as shown in the config below.
    weblogic.jdbc.connectionPool.bobePool=\
    url=jdbc:oracle:thin:@localhost:1521:<sid>,\
    driver=oracle.jdbc.driver.OracleDriver,\
    loginDelaySecs=1,\
    initialCapacity=10,\
    maxCapacity=22,\
    capacityIncrement=5,\
    allowShrinking=true,\
    shrinkPeriodMins=3,\
    testConnsOnReserve=true,\
    testTable=dual,\
    refreshTestMinutes=5,\
    props=user=<username>;password=<password>
    The problem I am facing is that some connections remain active
    after the SQL query has finished. The no. of open connections
    keep on piling up till the limit of 18 connections is reached and
    ultimately at that point weblogic hangs.
    Has someone else faced this problem...and found a solution??

    Hi Caren,
    Weblogic doesn't close connections on "time-out". There are some reasons
    for this. The most important one is that even if you have such a
    functionality,
    in case of a connection leak all the available connections can be trashed in
    a matter of milliseconds, so it wouldn't help at all. Though, weblogic does
    close leaked connection when they are garbage collected, but it's easy to
    see
    that it doesn't help a lot, too.
    So you need to make sure that all the JDBC objects are closed properly,
    for example like in this code:
    try {
    } finally {
    try {resultSet.close();} catch (SQLException se) {}
    try {preparedStatement.close();} catch (SQLException se) {}
    try {connection.close();} catch (SQLException se) {}
    Also it's possible that you simply don't have enough connection.
    You could try to increase size of the pool.

    Closing the DB connections is important. But is there any parameters to be
    set in the WebLogic configuration in order to release the connection whenit
    hasn't been closed for a long time? Say, setting the connection timeout?
    Many thx!

    Do you close the DB connections in a finally block after you've finished
    using them?
    If not your application is leaking the connections and sometimes GC is
    not able or does not free those in a timely manner.

  • Unable to create dynamic JDBC Connections in RMI Server

    Hi,
    Goal: Using Swing client to connect to a variety of JDBC databases via RMI dynamically....
    J2SE : 1.4.2
    J2EE: 1.31
    Databases: Oracle 9i(R2), MySQL 4.0, MS Access 2000
    Platform : Windows 2000 SP4 (Professional and Server)
    I have a working client-server application using RMI to connect to a single database. I want the ability
    to create JDBC connections dynmically by invoking a RMI method after it has been bound. Presently
    I am getting null pointers. Anybody offer any solutions or work arounds?

    Goal: Using Swing client to connect to a variety of
    JDBC databases via RMI dynamically....Actually what u want from the client swing is to form a Form using the datamodel from the database, invoke query as the client is allowed and wants and update changes. I hope I got it right, thats what u want.
    Actually as per my knowledge goes thats what any Database 3-tier program should do.
    I have a working client-server application using RMI
    to connect to a single database. I want the ability
    to create JDBC connections dynmically by invoking a
    RMI method after it has been bound. Presently
    I am getting null pointers. Anybody offer any
    solutions or work arounds?Database connections are only needed as long as the query to the database are being processed. So for ur solution if u have a RMI method that, will invoke first, the database connection and then process the query and then disconnect it , would be enough. When multiple clients will call the method there will be multiple connections to the database as they can have threads working or if u want one process at a time u can sycronize the method. This RMI method will only return the result set of the query and that would be enough for ur solution. Now to be able to say why ur getting null pointers I would need the code u r using.

  • Steve Muenchs "Dynamic JDBC" on WLS 11g (10.3.1)?

    Hi,
    I try to run Steves Example "11g Dynamic JDBC Credentials for Model 1, Struts, Trinidad, and ADF Faces Rich Client" on Standalone WLS 11g (10.3.1) but it doesn't works... on integrated WLS it runs without problems. The WLS-Log shows:
    Modul:     oracle.adf.mbean.share.config.ADFConfigLifeCycleCallBack
    Message:     Failed to create config mbean.
    details: java.lang.Exception: oracle.mds.core.MetadataNotFoundException: MDS-00013: No Metadate for Metaobject "/META-INF/adf-config.xml" found.
    Does somebody have the example to run brought? Or if new settings are necessary for the example on WLS 11g?
    Kind regards
    Martin

    Hi,
    since Steve's solution has nothing to do with the adf-config, I suggest you create a simple testcase that reproduces the problem. It appears as if the ADF binding is not set up properly

  • Workaround for using Oracle JDBC extension with WLS pooling

    Reading the newsgroup I saw that many of us encountered the problems
    with ClassCastException when tried to use Oracle JDBC extension
    with WLS pooling. I also had.
    In this case BEA recommends to use dangerous
    method getVendorConnection() which exposes
    the physical connection object to your code.
    Yes it's really dangerous because of unsafe usage may breaks
    WLS pooled connection(s).
    Moreover, this practice will make your JDBC code
    unportable (your JDBC code in addition to Oracle dependence
    became Weblogic dependent):
    void doSmth() {
    Connection con = ...;
    Connection vCon = ((WLConnection)con).getVendorConnection();
    // + mess of usage con in one places and vCon in others
    // (where Oracle extensions are needed)
    // !Don't forget to don't close vCon!
    Sux.
    I found the workaround.
    Introduction
    ============
    Yes the real cause of ClassCastException is that
    in depth of Oracle driver the casting
    to class oracle.jdbc.driver.OracleConnection
    (not to interface oracle.jdbc.OracleConnection)
    is performed.
    Someone can say that this is bug or pure desing.
    Weblogic pooled connection provide dynamic
    implementation for all public interfaces
    which real physical (wrapped) connection object implements.
    Great feature!
    But I guess that all interface methods implemented
    by simple call-delegation to physical (wrapped) connection object.
    In case of oracle.jdbc.OracleConnection interface
    this approach doesn't work for at least one its method:
    public OracleConnection unwrap()
    WLS pooled connection shoudn't implement this method by
    delegation to physical connection object BUT should
    return physical connection object itself!
    // Wrong implementation of unwrap()
    // delegation is used
    public OracleConnection unwrap() {
    return physicalConnection.unwrap();
    // Right implementation of unwrap()
    // physical connection returned
    public OracleConnection unwrap() {
    return physicalConnection;
    Workaround
    ==========
    1. Develop your own OracleConnection wrapper class:
    import oracle.jdbc.OracleConnection;
    import weblogic.jdbc.extensions.WLConnection;
    public class MyOracleConnectionImpl implements OracleConnection {
    private OracleConnection con;
    public MyOracleConnectionImpl(OracleConnection connection)
    throws SQLException
    this.con = connection;
    public OracleConnection unwrap() {
    return (OracleConnection)
    ((WLConnection)con).getVendorConnection();
    /* Implement all other methods by delegation to con object */
    2. Don't get Connections directly from DataSource --
    develop your own simple (may be static) utility
    class which retrives Connections from dataSource
    and returns them wrapped into your MyOracleConnectionImpl
    to your code from some method:
    puclic abstract class MyConnectionSource {
    public static Connection getConnection() {
    Connection con = // get it from DataSource
    return new MyOracleConnectionImpl((OracleConnection)con);
    3. Add attribute RemoveInfectedConnectionsEnabled="false"
    to definition of your JDBCConnectionPool within config.xml
    You may do it because of you `safely` use vendorConnection --
    you don't expose it to application code.
    4. Enjoy the Oracle JDBC extensions in your code!
    Example:
    Connection con = MyConnectionSource.getConnection;
    ArrayDescriptor add =
    ArrayDescriptor.createDescriptor("your_type", con);
    Hope it helps to someone.

    Hello Eugene Voytitsky,
    Thanks Eugene Voytitsky for your idea
    I have tried the solution suggested by You, but it did not work.
    It still throws ClassCastException.
    I am sorry for posting the whole code of two classes below.
    I did this to give you more clarity.
    I am also indicating the place where the exception was thrown..
    Please let me know if I am doing something wrong.

  • Problem creating dynamic pools with JdbcServices?

    Hi
    I am using WL Server 6.1 and am trying to create dynamic pools using the JdbcServices
    object. Basically, I create a properties object, and fill it with the properties,
    and then pass it as a parameter to the CreatePool command.
    I have noticed that whenever I set the initialCapacity property, an exception
    gets thrown. The pool gets created and is visible in the admin console, but I
    cannot do any operations on the pool.
    It seems to work if I don't set initialCapacity. In this case, initialCapacity
    defaults to 0 (and not 1 as the documentation says).
    Could the Weblogic people throw some light on the issue? This is very important
    for our release.
    Thanks in advance,
    P Kesh

  • Does WLS use OracleOCIConnectionPool to create it's pool?

    Hello,
    I have WLS 8.1 SP2... it ships with oralce jdbc driver version 9.2.0.0 I think...
    When WLS creates a connection pool, does it use the OracleOCIConnectionPool class from the oracle jdbc driver? OR does it use the OraclePooledConnection class?
    Thanks!

    KeithHi. We use our own pooling implementation. We do not use dirver-internal pooling,
    and don't recommend them for use with WebLogic.

  • A question about creating a Connection pool that uses Oracle JDBC

    Dear all,
    I have an issue with creating a connection pool within a web application in order to be used by several servlets. I appreciate if you could kindly give me a hand.
    I'm using:
    Web server: Apache-tomcat: 6.0.18
    Oracle Database 11g Enterprise: 11.1.0.6.0 - Production
    Operating system: Linux (ubuntu 8.10)
    IDE: Sun Netbeans
    Oralce JDBC Drivers: 11.1.0.7.0-Production (ojdbc6.jar and orai18n.jar)
    JDK 1.6
    Usually, just for creating a connection to my database (without using a connection pool), I proceed in the following way:
    String dbURL = "jdbc:oracle:thin:@localhost:1521:database01";
    String username = "scott";
    String user_password = "tiger";
    String userSqlQuery = "SELECT * FROM mytable";
    Connection connection = DriverManager.getConnection (dbURL, username, user_password);
    Statement statement = connection.createStatement();
    statement.executeUpdate(query_text);This works pretty well allowing to communicate with my oracle database. By this method I have run several projects
    with different queries (SELECT, INSERT, UPDATE, DELETE ,etc.) and each time it worked without any problem and
    returned the result of the query. Therefore I think that there is no problem with JDBC drivers
    However, when I want to create a connection pool, it seems that the lookup method cannot locate Oracle JDBC drivers. That is,
    try
         InitialContext ic = new InitialContext();
         Context envContext  = (Context)ic.lookup("java:/comp/env");
         dataSource = (DataSource)envContext.lookup("jdbc/oracle11gEnterprise");
           Connection connection = dataSource.getConnection();
    catch (Exception e)
         e.printStackTrace();
    }Just after calling dataSource.getConnection() the java.lang.NullPointerException is thrown.
    Any idea?
    Thanks in advance,

  • Slow performance WLS with jdbc pools

    Hi all, we have follow configuration of our system: the server with applications and server with jdbc pools. Recently we get strange situation. The server with jdbc pools it seems hung. We get thread dumps for this server and we see that it not hung, but normally work but very slow. Many weblogic.kernel.Default threads were busy by rmi database calls (see below). Anothe strange that before slowing server work nothing enties in server log. Last entry in server log were one hour before slow work. May someone propose why this situation can occure?

    -- end of trace</b>Hi. It seems you're doing JDBC in an external client, using our RMI-based
    JDBC wrappers to the actual connection in the WLS server, and you are
    doing LOB retrieval. This means your query goes from your client to
    the WLS process, and then to the DBMS, and the LOB data (big) has to go
    from the DBMS to the WLS process and then back over RMI to your client.
    This is bound to be inefficient. If you can move your JDBC to a JSP or
    other serverside class, it will be much faster. Otherwise, if the
    management that WLS provides is not strictly necessary for the LOB
    manipulation, it may be faster to get that directly from the DBMS to
    the external client by using the vendor's JDBC driver directly.

  • Dynamic Connection Pool Creation Failing in a cluster

    Hi,
    I am trying to create a connection pool in a clustered environment. This connection
    pool is created lazily behind a Stateless Session Bean. We first attempt to determine
    whether, the connection pool exists using JdbcServices.poolExists(someName), and
    create it if it does not exist. A failure occurs on creation because it looks
    like the connection pool might have been created by a bean on a different weblogic
    VM instance. Is there any way to dynamically create a connection pool and make
    it visible to the whole cluster? Thanks in advance for any help. Michael Dolbear

    The only way to do it is using MBeans. You could search this newsgroup
    for "JDBCConnectionPoolMBean" to get an idea of how it could be done.

    Slava,
    I am working with Mike on this issue and wanted to add some moreclarifications.
    We have a two server cluster where one of the EJB's on one of the Managedservers
    creates the connection pool. The problem comes in when a request comes tothe
    second server in the cluster. The connection pool is created by the firstserver
    but it is only assigned to the first server in the targets section on theconsole.
    It isn't assigned to the cluster. Is there a way to programmaticallyassign the
    pool to the cluster instead of just the server that created the pool?

    Hi Michael,
    Could you show us the code? Without looking at the code
    I can only say that JdbcServices.poolExists(someName)
    returns true only in case the pool is up and running.
    If the connection pool MBean was created but not assigned
    a target, subsequent tries to create it would fail.

  • Microsoft SQL Server JDBC driver and WLS JMS problem?

              Greetings,
              I'm using the Microsoft SQL Server JDBC driver with WLS with JMS
              persisted to SQL Server, during WLS startup the JMS attempts to
              read the JMSStore and JMSState tables in the db, if they are
              already present (say, from a previous run) the driver kicks out:
              java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]ResultSet can
              not re-read row data for column 1.
              If the tables are not present, then WLS creates them and
              everything proceeds fine. Now, its not a good thing to attempt
              to reread row data for a ResultSet, especially for portability. Why is WLS JMS
              doing this? is there some config I can use to adjust JMS startup behavior for
              persisted JMS stores?

              Tom,
              thanks for the info, I'll bring this to support.
              I did try the weblogic jDriver for SQL Server and it works fine, so i think it
              must be the way JMS is interacting with the MS driver.
              here are my components:
              WLS 6.1sp1
              Microsoft® SQL Server™ 2000 Driver for JDBC™ is a (Type 4 JDBC) which provides
              partial JDBC 2 support (no blobs, clobs, etc)
              MS SQL Server 2000 (sp2?)
              thanks!

  • Which BC4J / JDBC pooling configurations are global for a JVM?

    There are several documents and postings saying that some of the BC4J / JDBC Pooling properties are unique for the JVM.
    So if i have 3 WAR files with 3 different settings in bc4j.xcfg (transaction factory, pooling settings) some of the settings are ignored after the first AM Pool is instanciated. This could be the reason for some "unreproducable" problems we have.
    So please provide us a list, which properties additional to the ones below are global per JVM and which are really used from the bc4j.xcfg.
    1. Getting the Connection object out of ApplicationModule says about the TransactionFactory
    Please not that this property is a static BC4J property. Meaning that the value of this property when the first ApplicationModule is created is the value which will be used. If you have multiple ApplicationPool(s) then it is necessary to define the property in all configurations, dynamically, or as a system property.
    2. http://www.oracle.com/technology/products/jdev/tips/muench/ampooling/index.html says about jbo.ampool.monitorsleepinterval
    Since there is only a single application monitor pool monitor per Java VM, the value that will effectively be used for the AM pool monitor polling interval will be the value found in the AM configuration read by the first AM pool that gets created. To make sure this value is set in a predictable way, it is best practice for all application modules to use the same Pool Polling Interval value.
    and
    3. Since the tuning parameters for all ADF database connection pools - regardless of <JDBCURL,Username> value - will be set based on the parameters found in the configuration for the first AM pool that is created. To insure the most predictable behavior, it is best practice to leave the values of the parameters in the Connnection Pooling section of the Pooling and Scalability tab at their default values - so that no entry for them is written into the bc4j.xcfg file - and to instead set the desired values for the database connection pooling tuning parameters as Java System Parameters in your J2EE container.
    Sounds like this means the parameters: jbo.initpoolsize, jbo.maxpoolsize, jbo.poolmonitorsleepinterval, jbo.poolmaxavailablesize, jbo.poolminavailablesize, jbo.poolmaxinactiveage ?
    4. And http://oracle-web.petersons.com/bc4jdoc/bc_aappmodpooling.htm tells There is one connection pool manager for each business logic tier's Java VM. Connections remain in the pool until the Java VM stops running.
    Thanks, Markus

    Just another funny observation regarding BC4J parameter settings in 9.0.5.2:
    Setting jbo.ampool.sessioncookiefactoryclass in the jboserver.properties is ignored. Setting in bc4j.xcfg works.
    rgds, Markus
