Dynamic database connection using JNDI

How to pass the userid and password in get the database connection in weblogic 8.1 app server?
The following method throws exception while getting the database connection from oracle.
DataSource.getConnection(String username,String password)
Please advise if I need to use any other weblogic's method to get the dynamic connection. Every user of this application uses their own useid and password to connect to the database.
Any help is appreciated.

Hi,
I upgraded from WL8.1sp2 to sp4 and basically had to redo everything.
But since my understanding is that all patches and fixes are already
incorporated in this version, so I did not apply any patches. Now my
application which was previously working is getting an error with my
stateless session bean that I have not had before. This is the error
I get: I wonder why I would get oracle.jdbc.driver.Accessor.isNull
error now. Am I missing something in my install? Thanks for any help.

     at oracle.jdbc.driver.OracleResultSetImpl.wasNull()Z(OracleResultSetImpl.java:111)Hi. You should not have had to redo everything.... Yes, sp4 should contain
most all of the patches you may have been running for sp2, except for any
that you may have gotten fairly recently (found recently in sp2, but not
fixed in time for sp4)...
The exception above is an internal Oracle thin driver bug (it seems), so
the difference between sp2 and sp4 may have to do with the version of Oracle's
thin driver installed. If you want, you can try swapping out the sp4 version of
the thin driver, and trying the one from sp2, or the latest from oracle etc.
What is the full stacktrace of the exception? Is that it? No message?

    I've had a similar error. In a filter I was able to call lookup("java:comp/env") but got that exception when calling env.lookup("jdbc/mydatasource") in the init() method. Some nice people here answered that I should configure a jndi name for my datasource with a __pm termination, and did it without success.
    My workaround was to call lookup outside init, in the doFilter method.

  • How to create database connection using DB2Driver in JDeveloper 10.1.2.1.0?

    I am trying to create a JDeveloper/Data Connection using com.oracle.ias.jdbc.db2.DB2Driver. The driver is registered from a User Libraries: DataDirect JDBC. I have the following class path for the library:
    E:\DataDirect\3.4\lib\YMdb2.jar;E:\DataDirect\3.4\lib\YMbase.jar;E:\DataDirect\3.4\lib\YMutil.jar
    I have no trouble configuring the connection but when I test it and I got ‘No suitable driver Vendor code 0’. What’s wrong? I have successfully created several database connections using Oracle thin driver. This is first time I am using a third party driver. Has any one successfully create a database connection using the com.oracle.ias.jdbc.db2.DB2Driver?

    Hi
    Since the error points to the unavailability of the driver class,can you double check your library claspath entries again.
    I just tried a DB2 connection using the following properties and the connection went through fine:
    Driver class name: com.oracle.ias.jdbc.db2.DB2Driver

  • JPA using dynamic database connection

    Hello everybody.
    My current project requires JPA to use dynamic datasource connection. And I need to register the database connection implementation in JNDI. For the dynamic part, the idea is that if user A logs in, JPA should use A's id and pw to create a datasource connection. When user B logs in, JPA should use B's credentials to create a datasource connection instead. I poked around a bit in the forum and found out that DataNucleus supports Dynamic datasource for JPA.
    But, could any one tell me if JPA supports dynamic datasource connection out of the box? If it does, could you point me to some samples.
    Thanks!

    Hello,
    I am using an implementation of OpenJPA.
    I can now overwrite the database user id/password defined in a data source with Persistence.createEntityManagerFactory(name, props). However, the props (java.util.Map) needs openjpa.ConnectionUserName and openjpa.ConnectionPassword key/value pairs.
    My issue now is that the user authentication will be through LDAP, so I won't be able to know the password of any user ( therefore no value for openjpa.ConnectionPassword). I am wondering if there is any way that JPA can use LDAP for the data source authentication. I guess Datanucleus framework could probably do that, but is there any way other than using Datanucleus?
    Thank you.

  • Creating dynamic database connection (SQL server 2008) from Adf application

    Hello,
    I am creating an ADF Fusion Application. I use Jdev. 11.1.2.3.0 , WebLogic 10.3 and MS SQL server 2008 database. My question is that how can I create a database connection configuration file, now I connect to the database through hard coding, there should be a way to do this with sql server I think.
    my database name is : testDatabase
    my database username is : testUser
    my database password is : testPassword
    Anybody can help me please.
    Thanks,
    Shahe

    Hello Frank,
    The database schema is the same for all the users, but the location of the database differs, for example: I have set the hostname of the database to localhost because the database is installed on the local pc, but to other clients the database is installed on a managed server so in the hostname I should put the server's ip address or name. So I need an external file where I can set these options.
    Thanks,

  • Database connection using sqlplus

    Hi All,
    Can someone please do explain why am getting different result with the following scenarios:
    scenario 1
    1. I installed a database server and created a user ops$user1 identified externally.
    2. I created a unix user user1 (on the same machine) and make it member of oinstall and dba groups, set the environment variables the same as the oracle user.
    3. I create a database user user2 identified by password2
    4. Login as user1
    5. run sqlplus /nolog
    6. conn / <----- connection successful
    7. conn user2/password2 <---- connection successful
    scenario 2
    1. I created instantclient group and user (nologin) with home directory at /opt/instantclient (perm 750).
    2. I installed instantclient together with sqlplus and put it in /opt/instantclient.
    3. I modified the group profile of user1 by removing oinstall and dba, member it to instantclient group.
    4. set environment variables PATH, ORACLE_SID, LD_LIBRARY_PATH, CLASSPATH to include /opt/instantclient folder.
    5. Login as user1
    6. run sqlplus /nolog
    7. conn / <----- got an error, it says ORA-12545: Connect failed because target host or object does not exist
    8. conn user2/password2 <---- the same error
    9. conn user2/password2@oracle_sid <-- successful
    How come when using instantclient I need to supply the oracle sid? What we need is to connect using instantclient and need not to specify the oracle sid. Is this possible?
    Many thanks for those who will reply.

    Here it is:
    SQL> show parameter authent

  • Database Connection using PHP/MySQL on OS X

    I created a database connection originally on my XP machine
    using Dreamweaver CS2 and everything worked as it should. I
    recently switched to a Mac and CS3 and while I can see the
    connection file in the Connections folder, it appears grayed out in
    Dreamweaver. I tried to create a new data connection to see if that
    would solve this problem, but it won't let me. I typed in all the
    information and when I clicked "Test" or to browse for the
    appropriate database it pops up an error message saying "An
    unidentifiable error has occurred". I'm sure I could work around
    this by manually coding everything, but I'm a novice in programming
    and need to be able to use this feature. The worst thing about it,
    is that anytime I have to make a change to the web page, even if
    it's not regarding this section of code, it gets messed up. I have
    made backups, but once they are opened on the Mac they are messed
    up.
    I'm using Dreamweaver CS3, PHP/MySQL on a remote server as I
    still can't get my local web server functioning properly under
    Leopard. Any help would be appreciated because I haven't been able
    to find anything regarding this error online.

    That usually means that something is preventing communication
    between
    Dreamweaver and the testing server. It could be a firewall or
    anti-virus
    software. In the Testing Server section of the Advanced tab
    in Site
    definition, Host directory and URL prefix should both point
    to the same
    place. The first is the physical path to the top level of
    your site, the
    second is the URL you enter into a browser address bar to get
    to the
    same location.

  • Jsp and database connection using bean

    * I want create a bean to handle database connectivity.The
              <jsp:usebean> tag uses
              no argument constructor ..so I cannot pass the userid and password to
              the constructor.
              So how can I create a database connection when the user_id and password
              will be a part of parameter ?
              * Now I'm opening database connection in the jsp scriplets. Everytime I
              refresh the
              jsp page a new connection is created ? Is it not going to choke the
              database ? I cannot use connection pool because every user logs in with
              different userid.
              Thanks
              

    You can pass your arguments in this way:
              <jsp:usebean id="myBean" scope="page"/>
              <jsp:setProperty name="myBean" property="userId", value=<%= user_id%>/>
              <jsp:setProperty name="myBean" property="password", value=<%=
              user_password%>/>
              of course, in your bean class, you should create two setter methods,
              setUserId and setPassword.
              Hopefully, this will help you.

  • How many number of database connections used in a transaction

    Hi All,
    We are using weblogic 8.1 with Oracle 9i both running on windows 2000. We are trying to estimate the potential resource usage in the system we are building. As part of this activity we want to find out how the database connections are used for entity beans -
    If a session bean calls more than one entity beans
    (each method in the entity bean doing one update) does weblogic use the same database connection for all the entity beans or does it use seperate connections ? Is such behaviour documented somewhere ?
    Here the assumption is all the entity beans are linked to the same datasource.
    If the (default) behaviour is to use seperate connections is there a way to make it use one connection across multiple entity beans.
    Thanks

    Hi Bodapati,
    Sorry for the delay in replying to this.
    There is optimization, which will use the XA
    connections from the pool. Can you tell me what your
    observations are? I may be able to see if we can tune it.From our tests the XA driver too appear to make use of one connection only for the life of the transaction. There is a good document here explaining how it is ensured that only one connection is used - http://e-docs.bea.com/wls/docs81/oracle/trxjdbcx.html#1083132
    Quoting from the above URL :
    When a thread attempts to use a connection, the XA jDriver calls xa_open (and xa_start) to create the connection and associate it with the thread. After the database connection is created, the connection remains associated with the thread; the driver does not call xa_close. When the thread subsequently needs a database connection, it uses the same database connection associated with it, even though it appears to get and return a connection from the JDBC connection pool
    I am not sure why you say the connections will be
    blocked. One connection will be blocked only if you are > using non-XA driver to setup the pool, until the
    transaction commits. For XA there is no need to reserve
    the same connection for the transaction.Probably my understanding on this is incorrect and I need to read up. I was under the impression that - once a transaction begins, each connection used within that transaction, is enlisted as a part of that transaction and can not be used by in another transaction until the transaction commits or rollsback.
    Thanks

  • How to make common database connection using bean, etc.

    blingbling
    Edited by: BlingBling15 on Oct 22, 2007 1:16 PM

    Making a 'common' connection and passing it around is a bad idea. And making a new connection on every page, as you seem to have already guessed, also involves an overhead that you can do without.
    Like drvijayj2k2 has mentioned, you should use connection pooling.

  • How to make new database connection using Oracle BI Interactive Dashboards

    Hi,
    I install Oracle BI Intelligence on my system.
    I am using Oracle BI Interactive Dashboard. Here we have default database connection.
    but now i want to use it for my own database. Can any body give me guideline how to
    make a new data base connection using this s/w or how to connect to my database so
    that i can make my own reports.
    I am using
    http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/saw/saw.html
    this link.
    i make odbc connection which is fine.
    but
    Restoring the Business Intelligence Presentation Catalog and Updating Metadata
    The third point blow above heading is not clear.
    Thanks

    Umesh - in order to build Answers and Dashboard content you must first setup a Physical model, then a Business model, followed by a Presentation Catalog/Subject Area.
    All these tasks are carried out using the Repository Administration Utility.
    1) Import your physical tables using OCI/ODBC into the physical layer.
    2) Build your model
    3) Deploy
    Then you're ready to start building answers/dashboards.
    Good Luck.
