    Problem
    database url is generated based on SID
    eg: jdbc:oracle:thin:@localhost:1521:SID
    Solution
    (generate seperate url for SERVICE NAME)
    jdbc:oracle:thin:@localhost:1521/SERVICENAME
    ------------------------

    It is so clear: host not found error for network connection and the other SID servcie name not found means your oracle instance name is not up. check with srvctl status for given servcie name or node, else check CRS_Stat -t if you are using RAC.

  • Unable to create connection pool on weblogic startup

    Hi, I have a problem currently with the connection pool of weblogic 8.1 not being able to be created on a scheduled restart daily.
    The weblogic server is restarted daily at 6am. However, the oracle database is shut down for maintenance daily till 7am before it is up again. It is not possible to shift either timings of restarting weblogic and oracle.
    Is there any script or option settings in weblogic to reconnect the connection pool after 7am daily without restarting the weblogic instance?
    Please help. Thanks.

    Please help. Thanks.You can use the weblogic.Admin command line program to create, destroy, disable, or enable pools
    in a running server. However, the easiest thing to do is to define your pool to have an initial
    capacity of zero, so it is allowed to be created at startup, without needing to make any connections.
    Then it will self-populate as needed when application load starts, if/when the DBMS is available.

  • Cannot create connection pool with weblogic jDriver XA for oracle

    Hi everybody,
    we have serious problems configuring the weblogic jDriver for Oracle with support
    for distributed transactions.
    Everything works fine with the non-XA driver.
    We tried the suggestions given here before like setting the environment variable
    ORACLE_SID. However, this does not change the errors we get. We use Weblgic Server
    6.1 SP2 with oracle 8.1.7 (client and server) under Windows NT.
    When attempting to create the connection pool, we get the following exception:
    Starting Loading jDriver/Oracle .....

    branch. Check Oracle XA trace file(s) (if any) for database errors. The Oracle XA
    trace file(s) are located at the directory where you start the Weblogic Server, and

    Hi Michael
    Here is an example connection pool tag,
    <JDBCConnectionPool
    Name="oraXAPool"
    Targets="myserver"
    DriverName="weblogic.jdbc.oci.xa.XADataSource"
    InitialCapacity="1"
    MaxCapacity="10"
    CapacityIncrement="2"
    Properties="user=scott;password=tiger;server=ORCL"
    />
    Ensure that the server=ORCL is replaced by server=<what ever the Alias is
    defined in TNSNAMES.ORA file>
    You dont have to specify the URL for this.

    Hi everybody,
    we have serious problems configuring the weblogic jDriver for Oracle withsupport
    for distributed transactions.
    Everything works fine with the non-XA driver.
    We tried the suggestions given here before like setting the environmentvariable
    ORACLE_SID. However, this does not change the errors we get. We useWeblgic Server
    6.1 SP2 with oracle 8.1.7 (client and server) under Windows NT.
    When attempting to create the connection pool, we get the followingexception:
    Starting Loading jDriver/Oracle .....

  • Connection Pool using weblogic.jdbc.pool.Driver

    I am trying to use connection pooling in my JSP data access classes (which

  • Creating jdbc connection pool in weblogic 8.x server using oracle database

    Hi
    i am having oracle 9.2.0 and weblogic 8.1. i am new to oracle and jdbc connection pool. can any one explain how to make connection pool in weblogic.
    what will be the host name, port number??
    can any one explain
    regards,
    sekar.r

    The host name is the name or IP address of the machine running Oracle.
    The port number is the port the DBMS is listening on for connection requests.

  • Database connection pooling with weblogic 8.1.

    Hai All,
    I am new to weblogic database connection pooling.
    I am using Weblogic8.1 and want to use connection pooling to get a jdbc connection. my database server is Oracle 8.1.7.
    Things which i have done using the weblogic admin console.
    I have created a Jdbc connection pool named myconnectionpool.
    I have created a datasource named mydatasource.
    and named the JNDI as myjndi.
    Is the above process correct to create the connection pool in the weblogic8.1.
    I am not aware of the java code to get the database connection object from the connection pool which i have created.
    can any one please let me know the java code to get the connection from the pool.
    Any help is appreciated
    Thanks in advance
    pooja.

    Hai
    I have tried using the code u have mentioned but it returned me
    an error which is below.

    Hi Joe !
    I didn't get what you would like to point out. Actully, I am using same config.,
    but not to disclose the info. I gave you @test and username/password xxx/xxx.Ok. Now, assuming your pool looks like what I showed, the issue is probably
    that there are multiple Oracle driver zips around, and your standlaone program
    is using a different, newer, better one than the server. Our weblogic jar files
    include a classes12.zip Oracle thin driver, but there are multiple versions of
    classes12.zip, and the latest from oracle is better than the one we sealed into
    our packaging. Please use jave -verbose to identify exactly which Oracle sip file
    you are using in the successful case, then make sure this zip file comes before
    any weblogic stuff in your weblogic server's classpath, so we'll use the same
    driver. This should work. Edit the script you sue to start weblogic to verify
    the classpath does end up with the oracle driver ahead of all weblogic stuff.

    .MadhuriWell fine! That was easy. Your pool definition didn't have the same URL

    Now we need to simplify the problem. Please make a simple 15-line

    Java program like you'd find with the Oracle driver's examples, with
    no
    weblogic code in the picture. Just make a JDBC connection using Oracle's

  • Multiple Connection Pools in Weblogic

    Hello.
    We have a requirement whereby a user logging on to an existing web application has the option to then use another application that uses a different database.
    So.. I configured Weblogic with a second Connection Pool and a second Data Source, which references the new Connection Pool.
    In order acces the new Connection Pool, I tried this:
          Context ctx = null;
          Hashtable ht = new Hashtable();
          ht.put(Context.INITIAL_CONTEXT_FACTORY,
              "weblogic.jndi.WLInitialContextFactory");
          ht.put(Context.PROVIDER_URL, "ourProviderUrl");
          ctx = new InitialContext(ht);
          ds = (javax.sql.DataSource) ctx.lookup("newDataSourceName");but it didn't work. The Data Source couldn't be resolved (I don't have the stack trace of the exception at the moment.)
    How can I access the different connection pools?
    Am I going about this the wrong way?
    Help much appreciated!!

  • JDBC CONNECTION POOL FOR WEBLOGIC 8.1 TO ORACLE 8.1.6

    I am having problems with my connection pool. When I try to use the classes12 driver I get periodic TNS:connection closed errors and I can not set my initial pool size very high because one will fail with this error. When I try to use the ojdbc14 driver I get a character set not supported error. I am using the nls_charset12.jar file
    I am running weblogic 8.1 sp2. I am connecting to an Oracle 8.1.6 database.
    Any suggestions would be greatly appreciated.
    Thanks
    Eric

    Hi, thanks for your assistance. Here is the log dump.You should add a 1-second login delay for the pool. (loginDelaySeconds=1).
    Oracle can get swamped and ocasionally fail valid connection requests if
    too many are sent in a short time, such as when a pool is being initially
    populated. This setting will put a delay between successive connection
    requests, and should solve the problem.

  • Share the connection pool using weblogic

    I want to make shared connection with the JDBC driver, I read that the follow syntax:
    jdbc:oracle:thin:<USER>/@(PROTOCOL = TCP)(HOST = <HOST>)(PORT = <PORT>)))(CONNECT_DATA = (SID = <SID>) (SERVER = SHARED)))
    would let me have the JDBC connections shared with the others regular connections.
    Is it true ?
    Where to set such parameters in weblogic ?
    I'm currently using the JDBC driver ( SERVICES->JDBC->DATA SOURCES-> connection pool (tab) ) configured in the following manner:
    URL: +jdbc:bea:oracle://[dbIP]:1521+
    Driver Class Name: weblogic.jdbc.oracle.OracleDriver
    Properties:
    user=ETL
    portNumber=1521
    SID=LIVDEV1
    +serverName=[dbIP]+
    Thanks

    A 'shared' connection has to do with whether the DBMS spawns a separate OS process at the DBMS end to handle every single connection, or whether it spawns fewer, letting one DBMS-side process handle multiple logically distinct user connections, at some performance cost.
    Depending on the DBMS configuration and platform, this may be optional, the default, or impossible. As to clientside properties, try setting
    ServerType=shared.
    And just to be clear, this has nothing to do with how/whether the connection is to be used at the application end. It will
    always be considered as a single logical user, not a port for multiple independent client threads to use at once....

  • JDBC connection pools problems: weblogic doesn't release connections

    Hi all,
    we use Weblogic 5.1 in conjunction with Content Server 3.6 and Oracle
    8.1.6;
    We have this strange problem:
    Calling a page the connections, in the content server connection pool,
    grows up till the maximum. We think the problem is that Weblogic
    doesn't release used connections.
    Does anybody can help us? Did anybody had the same problem?
    Best Regards,
    Marcello Villani

    Hi. I'd have to see the code. When a pool connection is closed, it gets
    back into the pool. Until it's closed, it doesn't.
