Local Connection Creation Problem

I want to create a local connection, but it failed. It didn't appear any related dialog box after I click "Create Local Connections", it just remain same. Then, I try to use another way to create local connection by choosing "Local/Bequeath" for Connection Type via "New/Select Database Connection". However, it shown me "Status : Failure-Test failed: Incompatible version of libocijdbc[Jdbc:112030, Jdbc-OCI:112020" when I test the connection.
Now I really confuse and don't know how to solve the problem.
Software: Oracle SQL Developer (3.2.09)
Build MAIN: 09.30
Java(TM) Platform: 1.6.0_35
I help anyone can solve my problem, thanks.

SYSTEM and system_xe password is the one you put it in while setup.

  • Local Connection Problem

    Hello guys, I'm having a problem with my swf files
    communicating with each other.
    I am using Local Connection to coax them. The problem I'm
    having is that I have a main.swf which uses a MovieClipLoader to
    load swf files within itself. The main.swf actually acts as kind of
    a “holder” with a menubar above it.
    I want the user to be able to make any clicks on the menubar
    effect whatever happens in the current swf that is loaded. Thus, I
    had used Local Connection on one of the buttons in the main.swf:
    on (release) {
    section = "home";
    talkingLC = new LocalConnection();
    talkingLC.send("simple_lc", "comeBack", section);
    And at the top of the about.swf (which is being held) right
    now, I have this:
    listeningLC = new LocalConnection();
    listeningLC.comeBack = function(section) {
    if (section == "home") {
    trace("testing");
    this._parent._parent.dcMovie.gotoAndPlay(71);
    this._parent._parent.catMovie.gotoAndPlay(282);
    this._parent._parent.coolerMovie.gotoAndPlay(52);
    this._parent._parent.csMovie.gotoAndPlay(52);
    this._parent._parent.copter.gotoAndPlay(156);
    listeningLC.connect("simple_lc");
    stop();
    So far the tracing test shows nothing and of course, nothing
    is playing in this file.
    I'm not exactly sure what's going on, but would appreciate it
    if anyone can offer some help with this.

    I don't think that's what LocalConnection is intended for.
    Why can't you use something along these lines?
    on (release) {
    trace("testing");
    _root.dcMovie.gotoAndPlay(71);
    _root.catMovie.gotoAndPlay(282);
    _root.coolerMovie.gotoAndPlay(52);
    _root.csMovie.gotoAndPlay(52);
    _root.copter.gotoAndPlay(156);

  • How to access local connection factory created within Foreign Server in OSB

    Hi All
    I am facing an issue in my config plan. We have a RIB Foreign server with the following local connection factory:
    jms/RibAqJmsXATopicConnectionFactory
    I am using the below in my configuration plan:
    <cus:envValueAssignments>
    <xt:envValueType>Service URI</xt:envValueType>
    <xt:location xsi:nil="true"/>
    <xt:owner>

    </cus:envValueAssignments>
    and i am getting the below error:

    what am i missing here?

    [java] com.bea.wli.sb.transports.TransportException: Failed to lookup connection factory jms.RibAqJmsXATopicConnectionFactory
    Looks like the JNDI that you created for the ConnectionFactory is not reflected in the server.
    Login to WLS Console> Summary of Servers > server_name > View JNDI Tree
    Browse to the JNDI tree and see if your JNDI is visible there. If it is not then, please restart the server and recheck.
    Once you are able to find it in the JNDI tree, then execute the customization file.
    If you have modified the existing JNDI properties (that have a small exclamatory symbol) then any changes to those are not reflected till all the servers in the cluster are restarted.
    If it still does not work, then recreate a new Connection with a different name and then retry. It should work then.
    Thanks,
    Patrick

  • Change local connection string on remote server

    Hello,
     I have searched every post and tried every connection string there but can't figure out how to connect to my database on my  remote server. I am using Visual Developer 2005 Express Edition in C# and uploading it to a Windows server running asp.net 2.0. The domain has not resolved yet.
    I am so new to this and have followed many tutorials step by step but none of them address this issue. They just show how to upload it to the server.
    Do I need to use the SQL server provided by my host or can the database stay in the App_Data folder?
    My local connection string works locally:
      <add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\add_newSQL.mdf;Integrated Security=True;User Instance=True"
       providerName="System.Data.SqlClient" />
    When I uploaded to my server I changed \SQLEXPRESS  to (local) as advised in the forum.
    <add name="ConnectionString" connectionString="Data Source=(local);AttachDbFilename=|DataDirectory|\add_newSQL.mdf;Integrated Security=True;User Instance=True"
    providerName="System.Data.SqlClient" />
    When I debug a page I get the <customErrors mode="Off"/>
    error message even thought I have already set it in my remote web.config file which may be causing problems itself:
    <configuration>
    <appSettings/>
    <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=(local);AttachDbFilename=|DataDirectory|\add_newSQL.mdf;Integrated Security=True;User Instance=True"
    providerName="System.Data.SqlClient" />
    </connectionStrings>
    <system.web>
    <customErrors mode="Off" />
    <compilation debug="false" />
    <authentication mode="Windows" />
    </system.web>
    </configuration>
    Thanks for any help you can offer. I wish I could find someone to hire to do this part for me or teach me how over the phone. Any suggestions?

    Is this still an issue?

    Hi All,
    I have a two node installation of EBS R12.0.4 running on HP-UX Itanium.
    Last night we were having maintenance in our server room so we stopped the application and the database.
    Afterwards, on restarting, the database came up without a problem.
    On starting the application using adstrtal.sh script, the exits with status 5.

  • Cannot get Local Connection, No available resource, Wait-time expired

    Hi Friends,
    Please answer my queries below.
    Thanks and Regards
    Busincess Requirement
    I have to display a particular set of rows in a dashboard or screen, and it is being refreshed every 1 minute, also user can update from that screen displayed values.
    The below program extracts some data from database and passes to the front end through a collection where it is being displayed.
    Code Logic Flow
    1. CockpitAction calls CockpitOraDAO for database results
    2. CockpitOraDAO is a singleton class.
    3. After getting the CockpitOraDAO object, the action will then call the getLabAreaCockpitDetails() method.
    getLabAreaCockpitDetails will
         - Get the Connetion from the OracleConnectionManager class (It is a plain class with getPooledConnection() and releaseConnection() methods).
         - Execute the query and put the result to a collection
         - close the connection
         - return result to the calling action.
    This getLabAreaCockpitDetails() are called around once in every 1 minute
    So, I believe everytime a call is made to action for cockpit display, it will take the existing object of the CockpitOraDAO class and make a call to database. i.e there will be only one object of CockpitOraDAO reside in application server at any particular interval of time.
    My Understandings
    1. Only 1 object of CockpitOraDAO will reside in application server (provided it is not user longer and garbage collected) at a particular instance.
    2. Many objects of Connection will be created and destroyed.(Each time the getLabAreaCockpitDetails() method is called, we will get one connection from connection pool and in finally the Connection will be released to connection pool).
    My Problems
    It is showing the "Cannot get Local Connection, No available resource, Wait-time expired"
    after running around 1 full day.
    My doubts
    1. Can anybody say why I get this error ?
    2. There may be some connections are not closed. But I have checked at finally block, the status of the connection is closed after calling this method.
    3. There may be some problem due to the singleton instane of CockpitOraDAO, Is it affecting performance ?
    4. Is it valid that I have to make CockpitOraDAO as Singleton ?
    public class CockpitOraDAO extends DAOAdaptor //implements BISample
         private static CockpitOraDAO instance=null;
         private static boolean debug = true;
         * The below method will be used to provide the singleton intance of the CockpitOraDAO object.
         public static CockpitOraDAO getInstance()

    Hi,
    As you can see from other posts, this is a very common problem. Until now the cause always ends up pointing to a connection not being close.
    I suggest you try to run through a full single cycle of you app, while using the CLI monitoting to check that the connections created/closed matches the expected created/closed connections. Also that the number of free connections at the end is correct.

  • Flash Local Connection Issue

    Im fairly new to flash and am building a web page in
    Dreamweaver using two frames that contains flash movies on several
    pages. I have a movie on one page that contains buttons that link
    to another page, my problem is that I have another Flash movie in
    the new web page that needs to start at different frames depending
    on which button is pressed in the links section from the previous
    page.
    I have already set up a local connection from the links
    section to update the movie in the header (Top Frame) and this
    works fine, is the Local Connection method the way to go to achieve
    this or is there another way that im missing?
    Please help!
    If it helps the site im building is:
    www.ubeats.com
    and the movies im referring to are the 'Links' section (that
    appears on the right of the screen on all pages but the Buy Our
    Music page) and the 'Choose Retailer' movie on the 'Buy Our Music'
    page...one more thing, i have also set up a local connection
    between the 'Choose Retailer' buttons and the 'Retailer Display
    Area' above the table.

    I just set up 7 web pages with different swf files that start
    at different points. It leads to more files but it works, Hope this
    helps you arkhon13. Check out my site again to see it.
    Ive got a another problem now. My local connections seem to
    not work properly in IE on the PC! They work fine with Safari (Mac)
    and Firefox (PC) however which is the strange thing! Anybody heard
    of this before? Could it be something to do with the updates that
    have been made to IE 6 and would there be a quick fix for this?
    PLEASE HELP! Ive been trying to sort this out for ages!!
    Many thanks

  • Local connection

    hi!
    i want to connect my windowedapplicationA to
    windowedapplicationB using local connection..
    but i have error when i click button at windowedapplicationA
    to make connected to windowedapplicationB.
    the error sounds like this: Error #2044: Unhandled
    StatusEvent:. level=error, code=
    can anybody tell me what's the prob..
    thank you.

    when i struggle to find the solution of this problem..
    i can see a lots of people also face the same problem..
    a lot of solution suggested by th experts and no guarantees
    that it can solve the problem..
    why not just adobe flex make some proper video and proper
    notes to overcome this solution.
    the problem occurs when the users study through their note
    and video also..
    i am sure that the video and note handled by adobe flex about
    this problem can make the user like me shining and be the happy
    person in the world..
    yes. flex is best!

  • Local Connection Issue

    Hey everyone, I have a local connection established between
    two pages of my site which loads an image on my protfolio page when
    a link is clicked on my index page. The problem is, this only works
    when both pages are already open in a browser. I want to make it so
    that when someone clicks on a link on my index page, it opens the
    portfolio page and loads the corresponding image. Right now, I am
    trying to use navigateToURL to open the portfolio page but it
    doesn't seem to acknowledge any of my local connection functions
    until after the page is already loaded. This is the code I have
    right now:

  • Flash CS3 - Director Local Connect

    HI,
    I posted a problem in the Flash forums but its also
    potentiall a director problem. Please take a look and let me know
    what you think. Basically, putting a flash 8 cs3 file in director
    is crippling its ability to local connect with a flash projector
    file

    I do have the 10.1 update installed and have tested other
    flash 8 movies with flash 8 features( ie using filters which only
    shoews up if its working) which do work. The problem seems to be
    connected to the flash 8 files being generated by CS3. Also it is
    only effecting the local connect feature everything else seems to
    working normally. Do you know if CS3 is really creating flash 8
    files or its some kind of emulation that would confuse
    director.

  • Getting Local connection only

    I am having a problem with my WRT160N.  Sometimes I can only get a local connection but not the internet.  Most of the time if I restart the computer it will fix the problem but it is becoming a real problem.  Any suggestions?

    You this issue with the wired or wireless connection?

  • EPM Error while creating a local connection

    Hello everyone,
    I am a Dashboards designer and am new to BPC 10 MS. I am working on a dashboard that connects to BPC 10 MS to retrieve data via the EPM Connector. For this a 'Local' connection type must be used when creating the report in the Excel sheet using the EPM Add-In. I tried to create one but am facing a curious error which does not seem to be a known issue. I have installed the ODBO Client and therefore can create a local connection of type 'SAP BusinessObjects Planning and Consolidation'. Once I select this provider I entered my application server name and chose Windows Authentication for BPC MS as I have the service account credentials. I encountered an EPM - General error with the following text: Error while communicating with the server. Details: Framework message: Authorization failed. This error shows even if I'm using Excel and not Dashboards. If I use a different connector, I am able to access all the BPC data just fine. However, with local type (which is needed for the dashboard connector) it just doesn't work. I tried reinstalling the EPM Add-In as well as the EPM Connector without any change to the error.
    I am using Win7 32-bit, Excel 2010 32-bit, ODBO Client SP12, EPM Excel Client SP16 Patch 1, BPC 10 MS server SP08, Dashboards 4.1 SP1.
    Has anyone come across this before? Any help would be great as I'm very much stuck at this point.

  • Oracle.DataAccess 2.112.1.0 - Connection Pool Problem

    Hi,
    Oracle.DataAccess 2.112.1.0 is having connection pool problem. The no. of TCP connections to Oracle database keep increasing untill the server's session run out of limit. My application created connections, use them, close them, and dispose them properly. When using previous Oracle.DataAccess 2.111.6.20, the no. of TCP connections do not increase.
    My database connection string has "Min Pool Size = 3 and Max Pool Size = 150".
    With 2.111.6.20 version, TCP connection stays at 3.
    With 2.112.1.0, TCP connection keep increasing for every 5 minutes. I've tried to disable Self Tuning, but still can't prevent the connections from increasing.
    Later today, I downloaded Oracle.DataAccess 2.112.1.2 (it comes with ODAC 11.2.0.1.2) and test again, the problem is resolved... no more connection increases... but.... it is only for 32 bit Windows.
    Unfortunately, there is no Oracle.DataAccess 2.112.1.2 for 64 bit Windows Server 2008.
    May I know how can i resolve this problem on 64bit Window installed with Oracle 11g R2 client, which comes with Oracle.DataAccess 2.112.1.0, which has serious problems...(according to this 11.2 ODP.NET causing test runner failures )
    Many thanks for your time and answers!

    Hi,
    The only thing that jumps out within your problem description is that connections are being increased every 5 minutes. Are you sure its every 5 minutes and not 3 minutes which is the timing interval used by the Connection Pool facility to perform connection pool maintenance. If this occurs even when the application is idle then you could be running into the following known issue filed against 11.2.0.1.0 and fixed in 11.2.0.1.2.
    Bug 9711600 - CONNECTIONS INCREASE BEYOND MAX POOL SIZE EVERY 3 MINUTE
    This is specific to using the option CommandBehavior.CloseConnection when calling execute reader. Are you using this option and then also closing the connection in code before the datareader object is closed, if so you may be hitting this bug. You can also generate an ODP trace at level 15 of the behavior and if you see negative pool counts, that is also a diagnostic that points to this bug.
    This is fixed in 11.2.0.1.0 Patch 3 or later for x64. If you have support, I recommend you open a service request to verify if this is your issue and if a patch set may help you.
