Oracle DB on Redhat 5 connectivity with MS sql Server

Dear All,
Env.
Oracle EBS R12 – DB 10gR2 with RAC on Redhat linux 5
We want to connect OracleDB10gR2 to MS sql Server 2000/2005 on Windows 2003.
What is the way or which utility(ODBC) can be used to do this, anybody help us with detail??
Regards

HSODBC is what you'll want to do that, but you'll need a SQL Server ODBC driver that runs on Linux, and you'll have to get that from a 3rd party unless MS provides one.
Assuming you have Metalink access, the following note should help:
Note.264567.1 Ext/Pub How To Setup Generic Connectivity - HSODBC - on Linux:
Hope it helps,
Greg

    Hi there;
    I am a starter with Java and need your help with this little program.
    Create a console application project named Payroll that stores an employee's hourly pay rate and hours worked. Compute gross pay (hours times rate), withholding tax, and net pay (gross pay minus withholding tax). Withholding tax is computed as a percentage of gross pay based on the following:
    Gross Pay: Withholding percentage :
    0 to 300.00 ::::: :::::: Withholding percentage 10%
    300.00 to 400.00:::::: Withholding percentage 12 %

  • Connection with MS -SQL server Database

    Hi Experts,
    We are new with Oracle SES.
    We have created one table in MS SQL server 2005 in testing database called as Northwind, table is EMPdate with adding required column name as "URL","KEY","CONTENT","LASTMODIFIEDDATE","LANG".
    Now we create database source in Oracle SES by giving following things
    Database Connecting String: jdbc:sqlserver//<Loaclhost>:1433;databasename=Northwind
    UserId:
    Password:
    Query: Select URL,KEY,CONTENT,LASTMODIFIEDDATE,LANG,'text/html' CONTENTTYPE from EMPdate
    path separator: #
    Document Count : -1
    Parse Attributes :false
    And create Source & when we run schedule on this datadase source we got error that "invalid SQL command"
    Please can you provide sequence of steps to create MS SQL Server database source & generate the statistics.
    Thanks

    Hi,
    Thanks for the response.
    Running the Schedule for Stats collection -- I mean,the Schedule step whcih could be the immediate step just after database source creation
    The Crawl of the SQL Server not succeeded is Crawl Error
    which is located in C:\oracle\product\10.1.8\oradata\ses2\log direcory.
    We succeded with Web,ORACLE TABLE and FILE system sources as they were documented in the manual.
    Please Suggest all the steps to configure SQL server as Source

  • PeopleTools 8.49 PeopleSoft Database Cannot Connect with MS SQL Server 2005

    Folks,
    Hello. I am working on PeopleSoft PIA. My system is Windows Server 2003, MS SQL Server Express 2005 Standard, PeopleTools 8.49. I am setting up PeopleSoft Database \PsMpDbInstall\setup.exe and got the errors as follows:
    Error: Setup fails to connect to SQL Server. The default settings SQL Server does not allow remote connection.
    Then I type in "sqlcmd" in Command Prompt and got the same error as follows:
    Name Pipe Provider: Could not open a connection to SQL Server. MS SQL Native Client: the default settings SQL Server does not allow remote connection.
    In order to fix SQL Server 2005 remote connection problem, I have done the 3 steps as follows:
    Step 1: In SQL Server Surface Area Connection, enable local and remote connection, TCP/IP and Name Pipes, SQL Server browser Startup type "automatic" and status "running".
    Step 2: Create exception for SQL Server 2005 and SQL Server browser Service in Windows Firewall.
    Step 3: Add the default SQL Server Port 1433 into Windows Firewall.
    But the above 3 steps cannot resolve SQL Server Express 2005 remote connection problem. Can any folks help to resolve this problem ?
    Thanks.

    Folks,
    Management Studio can connect with SQL Server 2005 successfully.
    I have turned off Windows Server 2003 firewall completely. But "sqlcmd" in Command Prompt still connect with SQL Server 2005 because its remote connection is not allowed.
    Is the "not allow remote connection" problem caused by Windows Firewall or SQL Server 2005 itself ?
    Thanks.

  • Simple way to connect Oracle 11g XE with MS SQL Server 2000

    Is there a simple way to access SQL server database/ Tables within from Oracle 11g XE (Windows-32bit) on same machine. I am a novice so kindly keep it simple. Thanks

    To connect to a SQL Server you need to use an Oracle product called Database gateway for ODBC which uses a 3rd party ODBC driver to connect to the SQL Server.
    The easiest set up is to install DG4ODBC release 11.2 on the SQL Server. How to configure the Database Gateway for ODBC is described in note:
    How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on Windows 32bit to Connect to Non-Oracle Databases Post Install          [Document 466225.1]     
    when you install DG4ODBC on a 32bit Windows operating system and the instructions for a 64bit Widnows operating system can be found in this note:
    How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on 64bit Windows Operating Systems to Connect to Non-Oracle Databases Post Install          [Document 1266572.1]     
    The database gateway for ODBC is available for free from here:
    http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html
    Please make sure you select the 32bit or 64bit Windows operating system depending on the platform where you've installed the SQL Server and on which you now install the gateway and download the <win32/64>_11gR2_gateways.zip CD.
    Once downloaded, unzip it and install it using the Oracle Universal installer. Make sure you select the product Database Gateway for ODBC (there's also a dedicated SQL server gateway called Database Gateway for MS SQL Server - this gateway is NOT for free and it requires a separate license).

    when you want to connect from Oracle to a SQl Server you need the Oracle Gateway (HSODBC or even better Dg4ODBC) and a FOREIGN ODBC DRIVER for your foreign database - a SQL Server ODBC driver. You have to get this driver from a 3rd party vendor - Oracle does not offer any foreign ODBC drivers.
    So before being able to use DG4ODBC/HSODBC you need to install from a 3rd paryt vendor a SQL Server ODBC driver. Commercial vendrs are for example Data Direct, Openlink or Easysoft.
    On Unix ODBC drivers commonly also require a driver manager. If the ODBC driver vendor does not ship one with the ODBC driver you can get it from www.unixodbc.org

  • Anyone successfully set up connection pool in s1as with ms sql server 2000?

    As subject. Since I have seen a lot of posts about the NoSuchMethodException issue with various dbms providers, and the only "official information" I found thru different forums, google, different sun/javasoft sites and forums are this:
    http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fsunone%2F8172&zone_32=NoSuchMethodException&wholewords=on
    Which is wonderfully vague and provide not-so-much useful information...
    As for the information and suggestion posted by other forum members, most or all of them have experience with setting up Oracle, DB2, mySQL, etc., not aimed for MS SQL Server 2000 (you may think, I am just asking for it running MS SQL server with Java... oh well, not my choice)
    I still haven't seen any positive feedbacks on how this exception was caused and how to resolve it. I have literally exhausted all leads on how to fix this issue, so right now I'm only interested to know whether anyone in the forum actually have a successful connection pool set up with MS SQL server 2000.
    My platform:
    w2k sp3
    SunOne app server, update1, JDK 1.4.1
    latest MS SQL 2000 JDBC driver
    This fails with the NoSuchMethodException error:
    try {
    InitialContext ic = new InitialContext();
    DataSource ds = (DataSource) ic.lookup("test_db");
    con = ds.getConnection();
    System.out.println( "con is created -> " + con );
    } catch (Exception ex) {
    System.out.println( "failed -> " + ex.getMessage() );
    This works just fine:
    try {
    Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
    con = DriverManager.getConnection("jdbc:microsoft:sqlserver://xxx.xxx.xxx.xxx:1433;DatabaseName=testdb;SelectMethod=cursor", "username", "password");
    System.out.println( "con is created -> " + con );
    } catch (Exception ex) {
    System.out.println( "failed is fucked -> " + ex.getMessage() );

    Thanks for pointing out that article, I did not find it previously. After following the directions in the artile and your advise, now dbping seems to be able to connect to SQL server.
    Thank you very much.

  • Connection with ms sql 2005

    Dear all,
    I have two scenario to make connection with sql server 2005.
    1)sqlserver and database 11g both on windows xp 32 bit  .
    Is oracle Gateway best option in such scenario?
    2)Sqlserver on windows xp and 11g database on solaris 64 bit.
    Please provide step by step documents for this.
    Thanks

    Hi,
      You can use an Oracle Database Gateway for both scenarios.
    There are different combinations you can have depending how you want to setup your systems -
    1. sqlserver and database 11g both on windows xp 32 bit
    You can install the gateway either as part of the existing RDBMS install or in a separate ORACLE_HOME.  It is usually better to install the gateway standalone in a separate OH as this makes maintenenace easier.
    2. Sqlserver on windows xp and 11g database on solaris 64 bit.
    You can either -
    a) install the gateway on the Solaris 64-bit machine to connect to the SQL*Server on Wiondows. Again you can install standalone or as part of the existing RDBMS
    b) from the RDBMS on Solaris 64-bit you can access a gateway on the Windows machine. If this is the same Windows machine as in scenario 1 then you can use that gateway which is already installed.
    There are 2 gateways you can use to connect to SQL*Server -
    - Database Gateway for SQL*Server - DG4MSQL
    - Database Gateway for ODBC - DG4ODBC
    There are differences in the licensing and functionality of these 2 gateways which are discussed in these notes -
    Functional Differences Between DG4ODBC and Specific Database Gateways (Doc ID 252364.1)
    Gateway and Generic Connectivity Licensing Considerations (Doc ID 232482.1) 
    The following notes have further details on setting up the gateways -
