Connecting and Accessing Oracle with SQL Server

In Oracle and SQL Servers I'm Updating the data manually. But I want make it Automated Process(Updating required columns automatically) in SQL Server by using trigger during manual update in Oracle's table with respect to column .
Is this possible?
Im using Oracle 11g in linux and SQL Server 2005 in windows.
Both Servers are in different locations , but are in same network and not connected with ODBC , dblink .
I need your Valuable assitance and Helpful guide for succesfully completing my task.
Useful Replies are Highly Appreciated.

Hi,
Yes, you can update SQL*Server tables from Oracle using triggers if you install and use the Database Gateway for SQL*Server (DG4MSQL). You need to use DG4MSQL because it supports distributed transactions so that the Oracle and SQL*Server commits can be synchronised and both will be rolled back if there is an error.
You could use the Database Gateway for ODBC (DG4ODBC) but you would have to write your own error routines to handle problems if the commits fail in either Oracle or SQL*Server.
There is more information about the gateways in this note available in My Oracle Support -
Master Note for Oracle Gateway Products (Doc ID 1083703.1)
Regards,
Mike

  • How can I connect NetBeans 6.1 with SQL Server 2005?

    Hello guys...
    how can i connect NetBeans 6.1 with SQL Server 2005?
    there is no SQL Server in Server list when we create a new Web Project and choose Server.
    I'm new to NetBeans and this is my first time of posting.
    If has some errors and unwanted disturbing,pls understand me. Thanks.

    The JDBC-ODBC bridge wasn't recognizing any of the primary keys I had set up in SQL Server. After lots of head banging, here's the solution I came up with:
    1. Download the appropriate driver. SQL Server 2000 requires the SQL Server 2000 JDBC driver (http://www.microsoft.com/downloads/details.aspx?FamilyId=07287B11-0502-461A-B138-2AA54BFDC03A&displaylang=en).
    SQL Server 2005 download: (http://www.microsoft.com/downloads/details.aspx?familyid=C47053EB-3B64-4794-950D-81E1EC91C1BA&displaylang=en)
    3. After installing, right-click on "Libraries" in your project, and choose "Add Library...". Next, give it a name (i.e. SQLServer2000), and select "Class Libraries".
    4. On the next screen, find the JAR files (should be in C:\Program Files\Microsoft SQL Server 2000 Driver for JDBC\lib\), and add them under the "Classpath" tab. It will now be available under "Libraries" for future projects.
    5. You can now create a connection to a specific database under the "Services" tab (next to "Projects" and "Files" in the top left of the screen). Select "Microsoft Sql Server 2000 (Microsoft Driver)" and format the "Database URL" like this:
    jdbc:microsoft:sqlserver//YOURSERVER:1433;DatabaseName=YOURDATABASE
    1433 is the default port, though your DBA may have changed it.
    I posted a simpler version of this on the NetBeans.org FAQ page - they had the following title with no content on the answer page:
    "Cannot Select Tables From MsSql 2000 Because It Says No Primary Key Next To Each Table But The Tables DO Have A Primary Key. What Do I Do?"

  • Access Oracle from SQL Server using Oracle Provider for OLE DB

    Using
    - SQL Server 2000 SP4
    - Oracle 10g
    - Oracle10g Provider for OLE DB Version 10.1.0.4.0
    - Oracle 10g client
    Able to create linked server in SQL server to Oracle 10g and display list of tables in Oracle. However, when execute query, it gives
    Server: Msg 7320, Level 16, State 2, Line 1
    Could not execute query against OLE DB provider 'OraOLEDB.Oracle'.
    OLE DB error trace [OLE/DB Provider 'OraOLEDB.Oracle' ICommandText::Execute returned 0x80040155].
    Any idea what is the problem ?

    I'm having the same error message...But I'm connecting to a Oracle 8i DB......
    I think this has to do with SP4 for SQL....I will test this tonight....

  • Connection Pooling in Tomcat with SQL Server

    Hey Guys,
    I have been banging my head against this all day :( so i now turn to you for some help :) I have a web app that uses a database now i want to start using this connection pooling that is supposed to be greatly more efficient than creating a new statement each time i need something from the database.
    I have read many articles about this already today and feel that a lot of the contradict each other and one thing that i saw was that there seems to be different way of doing this.
    One solution i have tried to implement but have so far failed is as follows:
    In Web app:
    Update Web.xml to include:
    <resource-ref>
            <description>
                Resource reference to a factory for java.sql.Connection
                instances that may be used for talking to a particular
                database that is configured in the server.xml file.
            </description>
            <res-ref-name>
                    jdbc/BBL
            </res-ref-name>
            <res-type>
                javax.sql.DataSource
            </res-type>
            <res-auth>
                Container
            </res-auth>
        </resource-ref>Update Context.xml to include:
    <Context path="/TEST_CON_POOLING">
    <Resource name="jdbc/BBL"
    auth="Container"
    type="javax.sql.DataSource"
    username="sa"
    password="sa"
    driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
    url="jdbc:microsoft:sqlserver://10.20.1.91:1433;DatabaseName=BBL"
    maxActive="8"
    maxIdle="4" />
    </Context>And then my jsp to test this:
    <%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
    --%>
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

            Context initCtx = new InitialContext();
            Context envCtx = (Context) initCtx.lookup("java:comp/env");
            DataSource ds = (DataSource)
            envCtx.lookup("jdbc/BBL");
            Connection conn = ds.getConnection();
            //... use this connection to access the database ...
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery("select id from users");
            while(rs.next()){
                out.write(rs.getString("ID"));
            conn.close();
            %>
        </body>
    </html>When i actually deply this i get the following nasty tomcat error:

    Am i going about this correctly? Some tutorials i have read say that i should be updateing the server.xml file but whenever i go near that tomcat will not even start.
    Help greatly appreciated.
    If there is anything i have not posted let me know and i will get it up.
    Rob

    Updating the server.xml file used to be necessary. It is no longer required, and actually not recommended any more.
    The best approach I feel is as you have done here, putting the definition into a context.xml file specifically for this application.
    In fact it all looks pretty good to me.
    JDBC driver jar in [TOMCAT]/common/lib - check
    Configuration in context.xml rather than server.xml - check
    Using JNDI - check.
    Have you got the connection url right?
    Is it jdbc:microsoft:sqlserver or just jdbc:sqlserver ? I have seen both on various sites around the internet.
    What version of SQL Server are you using? Check its documentation on the JDBC driver as to what class to use, and what the connection string should be.
    Try it in a plain java class - can you get a connection just using plain JDBC code?
    What values do you use for that?
    Hope this helps,

    I saw this error when implementing this white paper previously.  I believe we ended up using the 32 bit version of SQL Server, and we might have ended up using R1 to get it to function.
    The problem is actually with the librfc32.dll...I don't believe it's compatible with SSIS 64-bit.

  • Downloading and installing Oracle (with sql plus) on Windows 7 Professional

    Hi,
    I got a new laptop which has Windows 7 Professional (64 bit). I intend to download Oracle 10g and would like to install bothe the database and the sql plus in this system.
    I would appreciate if somebody could provide me a link to the appropriate database (with sql plus installation capability). Also if available the installation guide.
    Thanks in advance.

    Hello,
    Windows 7 Professional (64 bit). I intend to download Oracle 10g and would like to install bothe the database and the sql plusOracle *10g* is not certified on Windows *7*, except with the latest patchset *10.2.0.5*, and its Premium Support ended on the *31st of July 2010*.
    You should download Oracle *11.2* which is certified on Windows *7 - 64 bit*.
    You'll find the Documentation and Download tabs on the link below:
    http://www.oracle.com/technetwork/database/enterprise-edition/overview/index.html
    About SQLPlus, it's delivered with Oracle Server and, in *11g*, you can still use it from a DOS box. If you intend to have a Graphical Tool, you should use Oracle SQL Developer instead:

  • EA 3.0  and schema Browser with SQL Server

    Once again a very good tool!
    In testing today I noted on a SQL Server connection in Schema browser even logged on as SA (like SYS in Oracle) I could not change from schema to schema as you can do in Oracle.
    If would be awesome if this could be resolved prior to GA.

    Yup, this is a bug. The Schema Browser in the EA is Oracle focused. But we intend to provide support for our supported third-party connection types (and Times Ten as well).

  • Need help with Thin JDBC connecting Oracle to SQL server.

    I am fairly new to JAVA. We have ORACLE 8.1.7 running on Solaris 8. I have a need to
    periodically extract data from ORACLE DB and transfer it to SQL Server. I am limited to
    moving data from the ORACLE/UNIX environment to SQL Server side.
    From what I have read, Server-side Thin driver should work.
    1) Are there any issues in trying to achieve this with ORACLE running on the UNIX platform?
    2) Will the Server-side Thin driver talk to both the DBs ?
    3) Is it possible to provide some sample code ?
    Thanks in advance,
    Solomon

    Quattro,
    I had complete success in reading from Oracle and writing to SQL Server. First of all let me thank you for all your help. I do have one last request. Its more on optimization than any thing else.
    I was trying to optimize my code by grouping both the connections in one place and to keep my reads and inserts together so that I don't commit at the end of each insert etc. I don't seem to have the scope rules under control yet. Could you suggest how to improve this:
    import java.sql.*;
    public class Test_Combined2 {
    public static void main(String args[]) throws SQLException {
    // Load the Oracle JDBC driver
    DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
    // Connect to the database
    // You must put a database name after the @ sign in the connection URL.
    // You can use either the fully specified SQL*net syntax or a short cut
    // syntax as <host>:<port>:<sid>. The example uses the short cut syntax.
    Connection con2 = DriverManager.getConnection ("jdbc:oracle:thin:@Test:1521:PSDEVElOP",
    "SOLOMON","SOL1");
    // Create a Statement
    Statement stmt2 = con2.createStatement ();
    String url = "jdbc:microsoft:sqlserver://INTRADEV:1433;DatabaseName=Measure";
    Connection con;
    String query = "select dataYear, dataMonth, yieldRate from tblYield " ;
    Statement stmt;
    try {
    Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
    } catch(java.lang.ClassNotFoundException e) {
    System.err.print("ClassNotFoundException: ");
    System.err.print(e.getMessage());
    // Select the ENAME column from the EMP table
    ResultSet rset = stmt2.executeQuery ("select year_start, monthofyear, percent_comp " +
    " from ps_usm_ytd_yield ");

    Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user ''.

    Hi Karthikeyan,
    This is not the issue at all. I can open the management studio by the same login id and password and also i can make the database jdbc connection from plain java file.
    It does not give me any problem by them.
    I'm unable to find the actual problem. May be i'm missing something in connection pooling.
    Please help.
    Regards
    Mina

  • Oracle 10g connectivity with sql server 2000 through oracle transpa gateway

    dear gurus.
    i am to connecto oracle 10g with sql server 2000 through oracle transparent gateway.
    i have installed transparent gateway and proper configured. also link is created.
    but when i execute query "select * from city@inventory" , so an error displayed.
    ORA-12500: TNS:listener failed to start a dedicated server process.
    kindly suggest me what could be the cause.
    regards,

    if the listener fails to spawn a dedicated server process it is commonly indicating an issue with the listener. So posting the listener and also a listener trace including a description of the env where you installed the gateway into which directory would be helpfull. Please keep also in mind if you have for example a 10.2.0.3 database and you install into this directoty a 10.2.0.1 gateway you have to reapply the patchset again do get consistent file version.
    So please describe more detailed your env.

  • Pool connection issue with sql server database in adf application

    Hi everyone
    I'm Developing a BPM application using Oracle bpm 11.1.1.5.0
    My JDeveloper version is 11.1.1.5.0 and my database is SQL Server 2008.
    I have created a new BPM application, an application module and created several view objects based on my sql server tables in the database.
    I have only one initiator user task which has a task flow and one jspx page for that.
    The problem :
    when I deploy the application, in the bpm workspace initiator page, the page is shown correctly only once every other time.
    I mean it's strange, the first time the user instantiates the process, it's shown correctly. The second time, it is not! The third time, it is! etc...
    The interesting part is, when the page is not shown correctly, if I refresh the page it will be shown correctly.
    Here's the log output from when the page is not shown correctly:
    JBO-30003: Application pool model.sam.specialAppModuleLocal fails to check out an application module due to the following exception:

    Hello thank you
    I found the file and changed the SQL Flavor to SQL Server but it still shows a blank page with the error instead of the page every once in a while.
    The error has changed though, now it is like this:

    I have noticed that this time only if the user submits the page, the next time he/she initiates a new task the error appears.
    Do u think this has to do something with pool settings or session settings or something like that?
    Thanks again

  • Connection with SQL Server 2000 to SQL Developer 1.2 Migration Workbench

    Hi all,
    I keep getting the following error with setup for SQL Developer 1.2 Migration Workbench connection to SQL Server 2000 database:
    "Status: Failure -Network error IOException: Connection refused:connect"
    I can access the Microsoft SQL Server 2000 database with username
    and password using Enteprise Manager. However for some odd
    reason the Oracle SQL Developer 1.2 cannot connect to it.

    I was having this problem too. I'll mangle this explanation, but Our SQLServer instance was on a local server with some named DNS something. So, to get to the server, we used theservername.outdomain instead of an IP. We could never get it to connect through the named server. We got an SQLServer instance going on a server that we could connect to through a regular IP, and it connected just fine.
    Also, are you using the JTDS driver, or microsofts driver? We have only been able to connect with the JTDS driver. http://jtds.sourceforge.net/
