Oracle and MS SQL Server

Hello All,
SQL Server is on Windows and our oracle is on Unix.
Now i want to use Hetrogenous Service of oracle to pull data which requires me to connect to system dsn. Now i create a system dsn in windows. How should the HS_FDS_CONNECT_INFO value set point sysetm dsn on windows system.
Regards,
Ron.

Do you have a metalink account? If so, try a search there. The first time I tried this, I found the docs on metalink very useful for setup and for troubleshooting later.
That being said, going the other way is much easier. Using DTS on SQL Server to pull data from Oracle only requires the 2 "layers" that already exist without having to set up a listener in between to simulate SQL Server as an Oracle instance. This may not be the case in all configurations, but was in my experience.

What are the Basic Differences between Oracle and MS-SQL server Database?

Hello,
anybody pls Guide me about the Differences between Oracle and MS-SQL server Database.and also IBM Databases also
Regards,
Balaram

SQL Server only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
In comparison with SQL Server , OracleDatabase supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
The SQL Server advantages:
SQL Server holds the top TPC-C performance and price/performance results.
SQL Server is generally accepted as easier to install, use and manage.
The Oracle Database advantages:
Oracle Database supports all known platforms, not only the Windows-based platforms.
PL/SQL is more powerful language than T-SQL.
More fine-tuning to the configuration can be done via start-up parameters.

Real-Time Data Sync-up between Oracle and MS SQL Server

Hi All,
I am looking for a solution to sync-up the data between Oracle and MS SQL Server in real time. Here, the structure of table is different (in the sense, the data in multiple table in SQL Server should be combined and put it in a single table in Oracle and vice versa).
Could anybody throw light on this plz?
Thanks in advance!

Comparing Oracle and MS SQL Server 2005

Hi!
I'm looking for documents which compare
features, price etc og the database and database related development-projects
I'm looking for resources that describe the terminology used of MS and Oracle for their db's.
I'm also looking for "Feuerstein"-best-practices in MS-world.
And at last I'm looking for simple and complex scenarios comparing performance/features of these db's.
And if possible, I want them from some "independent" sources...
Can anyone help?
Best regards
Bjorn Dorr Jensen

Hi Hans!
I think it would not be fair comparing Oracle 10g with SQL Server 2000.
So thats why I'm looking for comparison with SQL Server 2005,
but if you have something that compare Oracle 11 with SQL Server 2005,
let me hear about it :-)
The objective:
well, the last 2 years I worked with Oracle DB (tuning, pl/sql) in an serious manner.
and now I have to work with SQL Server (which I didn't work with the last 2 years),
so I'm interested in the differences.
For now it seems that many SQL Server features are primitive compared with Oracle, but Microsofts usability is much better.
O1.) But is it really more primitive or are I'm missing the nessessary experience with SQL Server? Thats some of the points I want to find out.
O2.) Analyzing our own requirements for features: when would it be better to use Oracle and when to use MS? How to make this measure-able?
Could one make an descision tree like:
when more than x users/day and clustering needed and db_size>y....
O3.) Should I promote in an environment with people only using MS-products,
promote the use of Oracle-DB? When will this be an good idea?
(I don't think it will be an good idea the other way around: moving from Oracle to MS SQL Server - or would it ;^)

SOS!! HBC's pointing ORACLE and MS-SQL server DB simultaneously Help!!!!!

Dear Partners:
Switching the Model.jpr->Business Components->Connections between
2 different DB connections (1) Ms-Sql server and (2) Oracle, I was able
to create Entity-and-View BC's from both databases. Also, I was able
to drag and drop datacontrols (tables) from both databases over
the same JSP/UIX page.
However, the application runs working only with either the MS-sql-BC's or
the Oracle-BC's, but not both simultaneously.
I beg your help to solve this issue.

I think you'll need 2 AMs for this to work. Each AM will have it's own DB connection. Unless one DB knows how to access the other DB's tables (using something like the Oracle Transparent Gateway).

How to create ODBC connection between Oracle 10g and MS SQL Server

Hi,
Can someone help us with the steps to create an ODBC connection between Oracle APPS using Oracle 10g database and MS SQL Server.
Requirement is to extract the transactional data from MS SQL Server on a daily basis and dump it into Oracle tables for an interface to be run. Currently it is being done through Dataloader tool which we feel is causing the data issue with Arabic characters. We want to create the ODBC directly between Oracle and MS SQL Server and check if the data is being pulled correctly.
The data is in sql server 2000 which has data in Arabic_CI_AS character set which is moved to Oracle 10.2.0.3 database with characterset AL32UTF8. The table data is moved to oracle using the dataloader 3.6 standard edition licensed version. We cannot change the character set of Sql Server 2000.
Please help
Thanks

Hi,
If you're trying to PULL data from SQLServer into an Oracle database, you wouldnt use Oracle ODBC driver for that, so you may want to post in the Heterogeneous Services forum instead:
Heterogeneous Connectivity
If you're trying to PUSH data from SQLServer into an Oracle database, you could use ODBC but most folks use OLEDB for that, and the following note on MOS should help:
How to Create a Sql Server Linked Server With The Oracle Provider for OLE DB (Doc ID 191368.1)
As with any NLS related issue, the first thing to do is dump the codepoints of the data in the Oracle database to see if it is stored validly, rather than relying on what the data "looks like" from some tool or other. It's best to check a single row, with only a few characters in it if you can, and you can do that via
SELECT DUMP(<columname>,1016) FROM <tablename> WHERE ...
Hope it helps,
Greg

Oracle Vs Ms Sql Server to handle around 6-7 Terabytes of data

I am considering Oracle 11G to handle around 6-7 Terabytes of data. This data will get accumulated over a period of 8 Months. Any data older then 8 months is purged out of the database.
Some of my MS SQL DBAs are saying SQL server offers similar performance at a very low cost. Is this really true? On What basis or parameters I can compare Oracle with MS SQL Server to nullify the price advantage?
I am not looking for ease of development, I am purely looking in terms of handling the huge data and still be able to provide good performance. Apart from performance if there is any parameter which makes any difference then please highlight.

As with any database requirements tend to drive the best technology to utilize.
I have run Oracle and MS SQL Server as well as MySQL and PostgreSQL.
If you are looking to support a fairly large user based on a database that is 6-7 TB is size where a good portiion of the data is subject to access then there is really is no comparison. Oracle does a much better job of handling large user bases with large data sets then MS SQL Server or MySQL at least based on my experience with them.
MySQL works very well for average user bases and smaller databases where the amount of data accessed is small. In other words you can have 6 TB of data and if you only frequently access 5GB of it then MySQL will work pretty well. If a large portion of the data is accessed all the time by many users you will struggle with MySQL. Most databases in MySQL I ran had issues at user bases of a few hundred with a database size of around 100G-200G, now my main expertise is in Oracle so there may be ways in MySQL to address this, but not easily as normal research and experiment channels did not yeild good results for me.
I have had a MS SQL Server databases with thousands of users fall on it face with a database only 20GB in size, its was completely CPU bound with 8 CPUs, then moved the database to Oracle with minor code changes to accommidate the differences between Oracle and SQL server using the same hardware specs and CPU was a steady 50% for the same work load and basically the same application.
I have found the capabilities of Oracle for large data sets and large users provide advantages that the other databases just did not offer or did not do well enough to overcome. Does not mean that Oracle is perfect, or the other databases are bad, but there are a lot of options and capabilities in oracle the I can take advantage of not to mention if I need to I can run on high end Unix hardware and goto 64CPU dozens of I/O channels, etc. I can not do that with MS SQL Server as Windows is my only option and the intel platform just does not hit the capabilties of higher end Unix Hardware.
When deciding the database to use cost should be the last factor used. If the database will not do what you need it to do then low cost does not help you. Deteremine the needs and requirements and then examine the database features and capabilities to determine what might work best for your situation. If it is a critical business function and you need the caddie then your business will pay for the caddie, it if needs a malibu then pay for the malibu or if it needs the yugo then pay for the yugo. Implement the right technologies where you need them. However there is something of an advantage to limit the number of technologies you will need to support as a jack of all trades never becomes an expert and that in of itself can be costly when trying to overcome issues developed by limitations of a database technology.

JDBC and MS SQL Server support

Hi everyone,
I'm using JDBC to access a MS SQL Server DB. To be more precise, I tried both the MS JDBC SQL Server driver as well as jTDS. Here's the question:
I'm using scrolling and committable cursors. My application could definetely make good use of full detection of inserted, updated and deleted rows - that is, I would like to use
ResultSet.rowInserted()
ResultSet.rowUpdated()
ResultSet.rowDeleted()
to automatically detect each row's status. The problem is the following:
DatabaseMetaData.insertsAreDetected() returns false
DatabaseMetaData.updatesAreDetected() returns false
DatabaseMetaData.deletesAreDetected() returns true
i.e. I can only detect deletes using either of the two above mentioned drivers.
Of course, I could construct an enhanced ResultSet class mimicking the behaviour I want, but I'd rather not.
The question is: Does anyone know a JDBC MS SQL Server driver supporting automatic insert, update AND delete detection?
If so, please give me a pointer.
TIA,
Carsten

I am in serious problem.
Jdbc doesnot support database connections without DSN.
Oracle and MS SQL Server 2000 both provides ADO for
connecting with their databases without DSN. But Java
doesnot support ADO.
Can anyone help me out?
I never use a DSN when connecting to Oracle. Nor is ADO used.
But then I do use the drivers that Oracle supplies.
And there are a number of MS SQL Server drivers, and they don't use DSN nor do they use ADO.

Replication between Oracle Server and MS SQL Server

Hello,
Does anybody know of a well known or reliable software that can do data replication between Oracle Server and Microsoft SQL server.
I suppose I can write my own version using Heterogenous Services in Oracle but I would like to know if such an automated replication between Oracle and SQL is available commercially.
Thank you.

Create and insert into table from Oracle to MS SQL server.

Hello,
Oracle Database 11g and Red hat 5
I have a very different kind of issue. I am handling the ORACLE db(remote db with all the important data). On the other side their is a MS SQL server db(local db with some testing data in it). All the users will access the ORACLE db for the actual processing but for sometime they need to apply some of their own concepts. So they will transfer the data from ORACLE to MS sql server.
I want to create a code in ORACLE db like a procedure , which will create a table in MS sql server , insert data into it,Also create some metadata table to keep some of my table's info on MS SQL serve db,If the table is present it should append the data, .... like many things ...
Overall my question is , how can i write a code to make these operation on a remote db, that to these operations are DDL and on MS SQL Server(Non-Oracle) ???
Please guide me with some ideas or solutions ...
Also provide if you have some good links to study ...
thanks in advance.

I'm not sure why you never visit http://tahiti.oracle.com prior to asking any question. Is it forbidden in your locale? Are you afraid of it? Will your salary be decreased when you visit the documentation?

Insert data into oracle based on sql server data(here sql server acting as source to oracle and destination to oracle)

Source is Oralce. Destination is SQL Server.
Requirement - I have to fetch sql server server data (empid's) based emp table and send this as input data to oracle to fetch and empid's are common.
I cannot use merge or loopkup or for each as oracle have too many records.
For example - In MS SQL - i have empid=1,2..Only these records, I have to fetch from oracle source into sql server destination. For this, I have adopted the below approaches...The major problem I face, when i build a empid's as a string, it is taking only
4000 chars. My string lenght is 10000. How do I breakup this string lengh and send to data flow task till all broken strings length passed to DFT.
Approach-1
created two variables - oraquery string, empid string
step1 - ms sql database - created sql task - declare @empid varchar(max)
SELECT @empid=
Stuff((SELECT ',' + empid
        FROM
        (SELECT DISTINCT convert(varchar(10),empid ) empid FROM emp
         ) x
        For XML PATH ('')),1,1,'')
select @empid =    '(' + @empid + ')'
select @empid
resultset=singlerow
resultset=resultname=0; variablename=User::empid (empid is declared as string)
step2 - oracle database - created data flow task
created oledb source
I put this statemnt in oraquery expression - "select * from dept where dept in "
+ @[User::empid] + "
expression=true
[OLE DB Source [1]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E14.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80040E14 Description: "ORA-00936: missing expression".
Approach-2
created three variables - oraquery string, empid int, loop object--when I put int then it is automatically setting to 0
step1 - ms sql database - created sql task - SELECT DISTINCT convert(varchar(10),empid ) empid FROM emp
resultset=fullresult
resultset=resultname=0; variablename=User::loop
step2 - created a for each loop container
for loop editor - for each ado ennumerator
enumerator configuration - loop
variablemapping - variable=empid;index=0
step3 - oracle database - created data flow task (outside for each loop. If I put inside it is taking long time)
created oledb source
I put this statemnt in oraquery expression - "select * from dept where dept in "
+ @[User::empid] + "
expression=true
Data inserting in a destination table but empid=0.

Sorry didnt understand if your step3 is outside loop how
@[User::empid] will get values for the empids from User::loop. The iteration happens inside loop so you
need to have a logic to form the delimited list inside using a script task or something and concatenating everything and storing to variable @[User::empid]
. Then only it will have full value used to be used in step3 query
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

Differnce Between Oracle 9i And MS SQL Server 2000

Hi,
What are the difference between Oracle 9i And MS SQL Server 2000.
Thnaks

Some links
http://www.google.lv/search?hl=lv&q=oracle+sql+server+difference&meta=
http://asktom.oracle.com/pls/asktom/f?p=100:1:487512552646613::NO:RP::
http://www.mssqlcity.com/Articles/Compare/sql_server_vs_oracle.htm
http://www.wisdomforce.com/dweb/resources/docs/MSSQL2005_ORACLE10g_compare.pdf
But you have to remember one big thing - I've not seen yet one compare that was completely indifferent to any of the included DB's. So you can be sure that every doc that you get on MS website will say that SQL server is better, every doc on Oracle website will say that Oracle is better. Every doc on other websites will say that better DB either is:
1) DB that has payed for the reserach paper
2) DB that was mostly used by the researchers
So of course you should be very cautious about each paper you get.

Unable to configure Oracle Publisher in SQL SERVER 2008 R2

Hi, All,
I am trying to talk to my Oracle database from SQL server. I already had Oracle Client 11g installed in my SQL server.
Following the guidance in the technet on configuring the Distributer successfully. I now trying to configure the Publisher, by choosing "Adding Oracle Publisher" option. Then it prompt for the user id & password, I have enter the login (which
is replication user id created in Oracle). I encounter following error msg:

Kindly pls help me.
Thank you.

1.Make certain that a current version of the oracle client code is installed at the distributor”, please install corresponding version of Oracle
Client tools on Distributor Box
2.Are you able to connect to your Oracle server from the Distributor Box?if so,Distributor
box needs to have Oracle client tools installed on it before you can setup replication , I hope you have installed the Oracle client tools on Distributor Box. If yes, check if using SQLPlus you can connect manually to Oracle server or not from your Distributor
Box.
Moreover,Please refer the below
Before attempting to configure the Oracle Publisher, SQL Server verifies that SQL*PLUS is accessible through the system path on the Distributor. If SQL*PLUS cannot be loaded, the following error message is shown:
"Unable to run SQL*PLUS. Make certain that a current version of the Oracle client code is installed at the distributor."
Try to locate SQL*PLUS on the Distributor. For an Oracle 10g client install, the name of this executable is sqlplus.exe. It is typically installed in %ORACLE_HOME%/bin. To verify that the path of SQL*PLUS appears in the system path, examine the value of the
system variable Path:
Right-click My Computer, and then click Properties.
Click the Advanced tab, and then click Environment variables.
In the Environment Variables dialog box, in the System variables list, select the Path variable,
and then click Edit.
In the Edit System Variable dialog box: if the path to the folder that contains sqlplus.exe is not present in the Variable
value text box, edit the string to include it.
Click OK on each open dialog box to exit and save changes.

What is the easiest way to export all tables data from Oracle to MS SQL Server?

Hello MS,
I would like to export all tables from Oracle 11.2 to MS SQL Server 2012 R1.
Using the tool "Microsoft SQL Server Migration Assistant v6.0 for Oracle" did not work for me because there are too many warnings and errors regarding the schema creation (MS cannot know it because they are not the schema designer). My idea is
to leave/skip the schema creation to the application designer/supplier and instead concentrate on the Oracle data export and MS SQL data import.
What is the easiest way to export all tables data from Oracle to MS SQL Server quickly?
Is it:
- the „MS SQL Import and Export Data“ Tool
- the “MS SQL Integration Services” Tool
- not Oracle dump *.dmp format because it is a propritery binary format
- flat file *.csv (delimited format)
Thanks!

Hi lingodingo,
If you want to directly export all tables from Oracle database to SQL Server, I suggest you use SQL Server Import and Export Wizard. Because you just need to follow the wizard with GUI, this is the easiest way.
If you want to make some modification for the tables‘ data before loading to SQL Server, I suggest you use SQL Server Integration Services package. For more details, please refer to the following similar thread:
https://social.msdn.microsoft.com/Forums/sqlserver/en-US/38b2bed2-9d4e-48d4-a33f-1d9eed1c062d/flat-file-to-sql-server?forum=sqldatamining
