Error when clustering a Connection pool

          We are testing the cluster feature of WebLogic 6.0 Sp2 on MS Win2K Pro and have
          run into a problem trying to cluster the petstoreServer in the Petstore domain
          to a remote machine. I cannot get the Connection pool, called "petstorePool",
          to load on the remote managed server. This is preventing the database from working
          properly on the remote managed server. What can I do to enable the Connection
          Pool to load properly? Below is the boot-up window for the remote managed server.
          Starting Cluster Service ....
          <Jul 13, 2001 8:19:40 AM CDT> <Error> <JDBC Connection Pool> <Cannot startup con

could you post your managed server's start script?
          Make sure Cloudscape's libs are in the classpath.

  • Error while creating JDBC connection pool for MSSQL database

    Hi,
    From my windows m/c, I am trying to configure a connection pool to connect to
    an MSSQL database on another m/c. While setting the targets, i get the error :-
    <Mar 11, 2004 6:17:52 PM GMT+08:00> <Error> <JDBC> <Cannot startup connection
    pool "gcdb_connpool" Cannot load driver class: com.microsoft.jdbc.sqlserver.SQLServerDriver>
    I have added the path of the jars for the driver in the classpath.
    Any help would be appreciated.
    Thanks.

    Hi. Read the weblogic startup script, and follow how it creates
    a classpath argument for the server. You must get the driver jars
    into that classpath.

  • Errors when trying to connect CRM 7.0 to Enterprise Search

    4.0 should be fine. My initial thoughts were on the script targetting a framework lesser than 3.5. Am bummed about the error cause in the line
    ClientContext clientContext =
    new ClientContext(client);
    it just creates an instance of the ClientContext class. It should have nothing to do with permissions cause it is not even trying to connect to the sharepoint site. So it looks like it can't find the assembly. Can you place the asembly
    under the Microsoft.Net\Framework folder of your machine. SSIS looks for custom assemblies in this folder on design time (Refer
    this) Worth a try hey!

    Have you recently patched/upgraded? This sounds like there might have been a problem relinking the executables / libraries, and/or a permissions problem. For example you may be referencing a 32 bit library with your 64 bit client.
    I believe I recently read a similar case - check Metalink for this symptom.

    Hi,
    Try installing Windows 2012 Live Essentials here.
    You will have to set up your Pop 3 or IMAP email account after installing the updated version per above.
    Are you using an Internet Service Provider Email  account or a cloud based (IMAP) Email account?
    Pop 3 accounts will require incoming and outgoing server addresses and any additional security settings required by your ISP. If you don't have the required settings for Pop 3 you will have to contact your ISP for those.

  • Keep getting sync service error when trying to connect my iphone 5S.

    Keep getting sync service error when trying to connect my iphone 5S. It freezes itunes and I can't do anything else. I see that there is an update for my phone and I need to back up, upload new apps, etc before installing. I plug my phone in and get this error every time. I am using a Win 7 SP1

    Howdy Susie48825,
    It sounds like you are getting an error that mentions the sync services when you connect your phone to your computer and so you cannot sync your device. I would use the troubleshooting from the following article that  mentions an error regardign the sync services named:
    iTunes for Windows: "Unable to load data class" or "Unable to load provider data" sync services alert
    http://support.apple.com/kb/ts2690
    Start with these steps:
    1. Check that iTunes is up-to-date
    Ensure that you have updated to the latest version of iTunes.
    2. Reset Sync History
    Resetting your Sync History is a simple step which may resolve some syncing issues. If this works, iTunes will prompt to Merge or Replace the information on your device when you next attempt to sync. To reset your Sync History:
    Disconnect your device.
    Open iTunes.
    From the Edit menu, choose Preferences.
    Click the Devices tab.
    Click the Reset Sync History button, and then reconnect your device.
    If this resolves the issue, and you know all of your contacts, calendars, bookmarks and notes are on your computer:
    Reset the Sync History again using the steps above.
    Select the device in iTunes and click the Info tab.
    Scroll down to the Advanced section, and under "Replace information on this iPhone/iPad/iPod touch" select Contacts or Calendars.
    Click Apply.
    If the issue persists, and you know all your contacts, calendars, bookmarks and notes are on your iPhone, iPad, or iPod touch:
    Remove all of the contact and calendar information from Outlook.
    Select the device in iTunes and click the Info tab.
    Scroll down to the Advanced section, and under "Replace information on this iPhone/iPad/iPod touch" make sure Contacts and Calendars are not selected.
    Click Apply.
    There are additional steps to use in the article if needed, but these will get you started.
    Thank you for using Apple Support Communities.
    All the very best,
    Sterling

  • Helpme I have error when I try connect from struts  to web service

    helpme I have error when I try connect from struts to web service using basic authentication . the error message is
    [SOAP Exception: fault code= SOAP-ENV Protocol; msg=Unsupported response content type "text/html" must be "text/xml"; ] Response was <html><body> 401 Unauthorized </body></html>
    I'm not using ldap for authentication only xml (jazx-data.xml) ... I already create user with jazn.jar for that user , and I dont know why it still error like that ..
    Please helpme I don't have anytime more to find the mistake , ??
    I'm using Jdeveloper 9i , and oc4j 9.0.4 Server (Not embedded with Jdev)
    But when I use with sample java client it success .....
    then I try with Struts the response is unsupported response content type text/html must be text/xml response was 401 Unauthorized

    1.The reason why this error occurs is, we are getting non SOAP response when the program is expecting a SOAP response. Did you set the proxy server correctly? Try to handle the exception and see the content type of the response in your program.
    2. While creating the client stub u must check an option for authentication for webservice .should solve ur problem.
    thanks

  • Error While Creating Informix Connection Pool

    Hi,
    I am trying to port an application from Weblogic 6.1 to Weblogic 8.1. The Application accesses Informix database. I used the following driver, url and properties while connecting to this database using Weblogic 6.1
    url:->jdbc:weblogic:informix4:snss_live
    Driver ClassName :-> weblogic.jdbc.informix.InformixDriver
    Properties :->
    port=22000
    user=snssadmn
    password=snssadmn
    server=10.115.26.40
    The above used to work fine with weblogic 6.1
    With Weblogic 8.1, I am using the following properties
    url :-> jdbc:bea:informix://10.115.26.40:22000;informixServer=10.115.26.40;databaseName=snss_live
    Driver ClassName :-> weblogic.jdbc.informix.InformixDriver
    Properties :->
    informixServer=10.115.26.40
    user=snssadmn
    portNumber=22000
    databaseName=snss_live
    serverName=10.115.26.40
    However using these properties I am getting the following error while deploying the Connection Pool to the Managed Server
    <Dec 29, 2004 12:26:53 PM EST> <Warning> <JDBC> <BEA-001129> <Received exception while creating connection for pool "Btv_Vms_Pool": [BEA][Informix JDBC Driver][Informix]INFORMIXSERVER does not match either DBSERVERNAME or DBSERVERALIASES.>

    Any idea as to why this is happening
    Regards
    Nitin Nair

    Hi. I suspect that the databaseName property is causing the problem in
    8.1. Remove it and see if that works. Also, try running:
    java utils.dbping, and giving it the properties it asks for, for your
    Informix connection. Once it succeeds in making a connection, it will
    print out the URL and properties it used. Then define the pool with
    those (and only those) properties and URL.

    However using these properties I am getting the following error while deploying the Connection Pool to the Managed Server
    <Dec 29, 2004 12:26:53 PM EST> <Warning> <JDBC> <BEA-001129> <Received exception while creating connection for pool "Btv_Vms_Pool": [BEA][Informix JDBC Driver][Informix]INFORMIXSERVER does not match either DBSERVERNAME or DBSERVERALIASES.>

The DBMS driver exception was: [BEA][Informix JDBC Driver][Informix]INFORMIXSERVER does not match either DBSERVERNAME or DBSERVERALIASES..>
    Any idea as to why this is happening

  • How to catch exception when have max connection pool

    hi,
    i have define in oracle user that i could have max 10 sessions at the same time.
    I have jdbc datasource & connection pool defined at glassfish server(JSF application).
    now, if in application is too many queries to the database then i have error: nullpointer exception - becouse when i try to do:
    con = Database.createConnection(); - it generates nullpointer exception becouse there isn't free connection pool
    i try to catch exception like this:
    public List getrep_dws_wnioski_wstrzymane_graph() {     int i = 0;     try {     con = Database.createConnection();     ps =    (Statement) con.createStatement();     rs = ps.executeQuery("select data, klasa, ile_dni_wstrzymana, ile_wnioskow from stg1230.dwsww_wstrzymane_dws8 order by data, klasa, ile_dni_wstrzymana, ile_wnioskow");     while(rs.next()){       rep_dws_wnioski_wstrzymane_graph.add(i,new get_rep_dws_wnioski_wstrzymane_graph(rs.getString(1),rs.getString(2),rs.getString(3),rs.getString(4)));       i++;     }     } catch (NamingException e) {         e.printStackTrace();     } catch (SQLException e) {         e.printStackTrace();     } catch (NullPointerException e) {         e.printStackTrace();         throw new NoConnectionException();  // catch null 1     } finally {     try {         con.close();     } catch (SQLException e) {         e.printStackTrace();     } catch (NullPointerException e) {         e.printStackTrace();         throw new NoConnectionException();  // catch null 2     }     } return rep_dws_wnioski_wstrzymane_graph; }
    but at line:
    con.close();
    i have nullpointerexception
    and
    at line
    throw new NoConnectionException(); // catch null 2
    i have: caused by exception.NoConnectionException
    what's wrong with my exception class? how to resolve it?
    public class NoConnectionException extends RuntimeException{     public NoConnectionException(String msg, Throwable cause){       super(msg, cause);     }     public NoConnectionException(){       super();     } }
    at web.xml i have defined:
    <error-page>         <exception-type>exception.NoConnectionException</exception-type>         <location>/NoConnectionExceptionPage.jsp</location>     </error-page>

    thanks,
    i did it and i have error:

                    throw new NoConnectionException();  // obsluga bledy na wypadek jesli braknie wolnych polaczen do bazy
            return conn;
    }and at my ealier code i have error:

    in code:

          i++;
        } catch (NamingException e) {

        } catch (SQLException e) {

        } catch (NullPointerException e) {
            e.printStackTrace();
            throw new NoConnectionException();
        } finally {
        try {

            e.printStackTrace();
            throw new NoConnectionException(); 
    return rep_dws_wnioski_wstrzymane_graph;
    }so what's wrong?
    i have limit max sessions 10 at oracle so i set at my connection pool 5 connections as max. But when i get max 5 sesssins and try to execute next query then i can't catch exception..
