Oracle 10g/11g to Sql Server 2005 Migration

Dear All,
I am a beginner to this migration Activities..
We have designed one Application which is havin Database as Oracle 10g.
and We had another small Application which is having Sql Server 2005 has Database.
Daily we need to convert DB of Oracle to Sql server DB in order to acces recent updated data..
Pls help me how to convert Database in Oracle 10g/11g to Database in sqlserver 2005..

Hello,
this is an Oracle forum and we are handling here migrations from foreign databases to an Oracle database.
For migrations in the other direction, in your case from Oracle to MS SQL Server, you need to read the Microsoft pages, e.g.:
http://www.microsoft.com/sqlserver/2005/en/us/migration.aspx
Daily we need to convert DB of Oracle to Sql server DB in order to acces recent updated data..Normally a migration is not a daily process, so I guess that you just want to transfer data from Oracle to SQL Server on a daily basis. If that is the case, you should consider to use our Gateways. Please start reading here:
http://www.oracle.com/technetwork/database/gateways/index-100140.html
Using the Database Gateway for MS SQL Server (DG4MSQL) or the Database Gateway for ODBC (DG4ODBC) you can copy your data from your Oracle database to your SQL Server database, using a database link in the Oracle database.
Please let me know whether this answer helped you.
Regards
Wolfgang

Oracle 10g dblink to sql server 2005

Hi all,
I'm conecting oracle 10g r2 (windows xp) with sql server 2005 (windows 2003 server)
After configure ODBC connection to SQLSERVER, the DSN is called HUAWEI_DCDB
I configure these three (3) archives:
1) C:\oracle\product\10.2.0\db_1\hs\admin\initHUAWEI_DCDB.ora

Anyone have idea about the error???
Thanks,

Hi,
You have the wrong values in the tnsnames.ora entry.
You have -
HUAWEI_DCDB =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1523))
(CONNECT_DATA=(SID=hsagent))
(HS=OK)
but the CONNECT_DATA information is incorrect. it should be -
HUAWEI_DCDB =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1523))
(CONNECT_DATA=(SID=HUAWEI_DCDB))
(HS=OK)
The sid needs to match the sid defined in the listener.ora for the gateway.
The actual tnsnames.ora entry should have spaces at the beginning of each line except the first, as they are lost in the forum entries.
Once this is fixed you may also have a problem unless you put a user and password in the create database link statement -
create public database link HUAWEI_DCDB connect to "userid" identified by "password" using 'HUAWEI_DCDB';
One other point is that 10.2 HSODBC is now desupported and has been replaced by the 11g Database Gateway for ODBC (DG4ODBC). You should plan to install and use that instead of HSODBC to be on a fully supported product.

Mike

Client transport between SAP on Oracle 10G and MS SQL server 2005

Hi Folks,
We have a requirement where we have to do client export/import from SAP ECC 6.O running on Oracle 10g and to SAP ECC 6.0 running on MS SQL server 2005.I want to know whether SAP supports this and patch levels of all components two systems should be the same.
Thanks in advance,
Basis Admin

Not recommendet because of potential :
- patch level inconsistency
- ABAP dictionary inconsistency (programs, tables)
- possible client independent configuration conflicts
existing config cen disturb "imported" client
imported config can ddisturb existing clients
If there are any inconsistencies mentioned above you are in trouble...

wojtek

Migrate oracle database to Microsoft sql server 2005

Hi All,
I have to migrate production oracle database to Microsoft sql server 2005. Below are the details:
Oracle database version: 8.1.7.4
Platform : Aix
Kindly help me out

Well, the traditional way would be to dump out all your data from Oracle tables as comma delimited flat files and import into SQL server. Plenty of examples online, like this is one by Mark Powell: http://www.jlcomp.demon.co.uk/faq/flatfile.html
Or if you have the budget you could think about buying a data mapping tool like File-Aid
As mentioned by another poster, you will still need to figure out how to replace all your triggers, stored procedures, etc on your new platform of course.

When will Oracle 10g/11g support Windows Server 2008 and AIX6.1

Hi all
I'm sorry if I post it in a wrong place... But I really want to know when will Oracle 10g/11g support Windows Server 2008 and AIX 6.1?
I've searched in metalink but found nothing useful. Is there anybody can give me a link of Oracle's roadmap for platform support?
Thanks!

Oracle does not announce release dates and neither
does any other software company.But Oracle does have a very good track record of supporting their products on new windows releases extremely close to the windows release date. Clearly they can't support on an unreleased platform though. Given that the launch of Server 2008 isn't even complete worldwide yet (19th March in the UK for example) it would seem that this enquiry is a little premature.

SQL Server 2005 Migration to Oracle 10g

Does anyone have any idea if a Migration Workbench beta plug-in exists for SQL Server 2005 to Oracle 10g. I have a production system waiting to be moved over to Oracle and the users are getting impatient.
If there is nothing yet, does anyone have an alternate procedure to migrate a small schema (20 tables + 10 stored procedures) with a large amount of data?

Probably late in the day for this but
The workbench cannot handle SS2K5 directly at the moment. However as long as no new SS2K5 functionality has been used with a few tweaks this can be achieved.
1. Firstly use the SS2K offline capture scripts to build the directories for the database(s) you want to capture.
2 Secondly edit
(a) SS2K_SYSLOGINS.dat and take out long SS2K5 user records
(b) SS2K_SYSINDEXES.dat change FIRST ( forth column) to a value (say hex 1).
(c) SS2K_SYSUSERS.dat change ROLES (sixth column) to a value (say hex 1).
This should now load into the workbench. If it does not check the error.log file in <OMWB HOME>\log.

SQL Server 2005 Migration Q's

Ok so I have a SQL Server 2005 database and have migrated it to Oracle 10g Rev 2..
All the text fields are right padded :( how do I stop the extra padding on the text fields is there a flag or something ?
thanks

What are the column types in SQL Server and in Oracle?
CHAR types are always padded to their full length with spaces whereas VARCHAR types only store what is actually there.

Oracle provider Issue in SQL Server 2005

Hi all,
On the dev server, I'm using SSAS 2005 (32-bytes) + Oracle provider for OLE DB to access my Oracle Database and it works perfectly.
On the production server, SSAS 2005 is running on a 64-bytes platform.
The Oracle client 10.2.0.1.0 (64 bits) has been installed containing the Oracle provider for OLE DB but unfortunately the Oracle provider for OLE DB does not appear in the list in BIDS when trying to create a date source.
Could someone help ?
Regards,
Juan

After much grief I figured this out and this works for me going from x64 sql 05 on windows server 2003 to x86 oracle 10g on another windows server 2003 box...
Software Prerequisites
•     x64 Oracle Client:
http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winx64soft.html
•     x64 Oracle Data Access Components (ODAC) http://www.oracle.com/technology/software/tech/windows/odpnet/64-bit/index.html
•     x86 Oracle Client:
http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winsoft.html
•     SQL Server 2005 SP2 (x64):
http://www.microsoft.com/downloads/details.aspx?FamilyID=D07219B2-1E23-49C8-8F0C-63FA18F26D3A&displaylang=en
Patch Level Required (As of Thursday, July 31, 2008):
•     Microsoft SQL Server Management Studio: 9.00.3042.00
•     Microsoft Analysis Services Client Tools: 2005.090.3042.00
•     Microsoft Data Access Components (MDAC): 2000.086.3959.00 (srv03_sp2_rtm.070216-1710)
•     Microsoft MSXML: 2.6 3.0 4.0 6.0
•     Microsoft Internet Explorer: 7.0.5730.13
•     Microsoft .NET Framework: 2.0.50727.42
•     Operating System: 5.2.3790
•     Oracle Data Access Components (ODAC): 10.2.0.3.00 (64-bit Oracle10g Release 2 ODAC for Windows x64)
1. install the x64 and x86 oracle clients on the mssql box
2. install the odac on the mssql
3. Verify that the registry settings at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSDTC\MTxOCI and
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSDTC\MTxOCI
are correct:
a.     OracleOciLib = oci.dll
b.     OracleSqlLib = orasql10.dll
c.     OracleXaLib = oraclient10.dll
4. Verify that your tnsnames.ora and sqlnet.ora files have the correct info to connect to the source Oracle 10g (x86) 32 bit source. Note if there is a DNS or other name resolution problem in the environment you may need to change your host entry in your tnsnames file to be the actual I.P. address of the source Oracle box, until the network issue is resolved by the applicable environments network engineer. Additionally, note that if your client tnsnames.ora file is not configured to match the network topology in use, you will have issues… loopback configurations particularly cause grief.
5. Update Machine.config Add the following binding policy:
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Oracle.DataAccess" publicKeyToken="89b483f429c47342" />
<bindingRedirect oldVersion="2.0.0.0-10.9.9.9" newVersion="2.102.3.2" />
</dependentAssembly>
</assemblyBinding>
</runtime>
6. Save the following as a *.reg file and run it...
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSDTS\Setup\WizardPath]
@="C:\\Progra~2\\Microsoft SQL Server\\90\\DTS\\Binn\\DTSWizard.exe"
7. Save the following as a *.bat file...
rem Progra~2 is short path name for "Program Files (x86)" and works around an Oracle client bug that doesn't like the ()'s in the path
start /B "C:\Progra~2\Microsoft Visual Studio 8\Common7\IDE" "C:\Progra~2\Microsoft Visual Studio 8\Common7\IDE\devenv.exe"
8. Save the following as a *.bat file...
start /B "C:\Progra~2\Microsoft SQL Server\90\Tools\binn\VSShell\Common7\IDE" "C:\Progra~2\Microsoft SQL Server\90\Tools\binn\VSShell\Common7\IDE\SqlWb.exe"
9. Create a shortcut that points to each of the batch files you just created and only launch BIDS or SSMS from those *.bat files...
10. create your packages, etc., as normal, but you will not be able to fully test them from BIDS or SSMS because they are 32 bit running in 64 bit o/s...
11. Create a job with a line similar to the following as a cmdexec type of job...
"C:\Progra~2\Microsoft SQL Server\90\DTS\Binn\DTExec.exe" /FILE "C:\SomeWidget.dtsx" /MAXCONCURRENT " -1 " /CHECKPOINTING OFF
12. your done...

BI Publisher 11g - calling SQL Server 2005 stored procedure error

Hi experts
I have been calling succesfully an SQL server 2005 stored procedure for the data model of a BI publisher report in 10g, passing it a customerNo parameter.
EXEC     [dbo].[usp_WelcomeLettersConsumerNo]
          @CustomerNo = :sCustomerNo
However it does not work in 11g I get the error:
[Hyperion][SQLServer JDBC Driver][SQLServer]Incorrect syntax near the keyword 'is'.
which is frustrating as there is no 'is' in the statement (perhaps it is picking up :s?) - I wonder does anyone know if there has been a change in 11g that may be causing this?
cheers
Tim

Cannot connect to Oracle 11gR2 database from SQL Server 2005

Both SQL Server (Windows) and Oracle (Linux) are in 64bit environments.
I have done the following on a Windows 2008 R2 with SQL Server 2005:
Install InstantClient from Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64) to C:\Oracle
Install oledb from 64-bit ODAC 11.2 Release 3 (11.2.0.2.1) for Windows x64 by executing install.bat oledb c:\oracle odac
Note: Not sure whether 11.2.0.2.1 version of ODAC will cause any problem since I cannot find 11.2.0.1.0 version.
I have checked the Allow inprocess of OraOLEDB.Oracle provider in SSMS.
I have executed sp_addlinkedserver @server = 'ORACLE_TEST', @srvproduct = 'Oracle', @provider = 'OraOLEDB.Oracle', @datasrc = '##.##.##.##:1521/TEST'
The ##.##.##.## is the ip address of the Linux server which has the Oracle 11gR2 database TEST.
I have executed sp_addlinkedsrvlogin @rmtsrvname = 'ORACLE_TEST', @useself = 'FALSE', @rmtuser = 'xxxx', @rmtpassword = 'yyyy'
The xxxx is the oracle username and yyyy is the password for the oracle user xxxx.
I know the oracle database TEST is up since I have setup connection in Oracle SQL Developer having:
##.##.##.## as the hostname
1521 as the Port
xxxx as the username
yyyy as the password
TEST as the service name
When I click Test Connection for the linked server ORACLE_TEST in SSMS, it just hang.
When I issue a query like select count(*) from oracle_test..xxxx.table1, it just run forever. I'm not so sure how to query an oracle table. I have also tried select count(*) from oracle_test.xxxx.xxxx.table1.
When I retype the password in the Linked Server Properties, it just run forever.
Do I need to create a tnsnames.ora on the Windows machine?
Do I need to change the tnsnames.ora on Linux machine?
I'm very new to Oracle.

This forum is dealing with connections from an Oracle database to SQL Server - so the Oracle database is the driving site and this is the way round from your linked server set up.
As you're suing the instant client you might post your issue in the instant client forum:
Instant Client

Oracle Source TO MS SQL Server 2005 Target

Hi there,
I need to extract data from my Oracle DW and push it into a dependant system's Microsoft SQL Server 2005 DB.
Could someone PLEASE give me some pointers?
Oracle DB 10.2.0.4.0
OWB 10.2.0.1
Thanx!

Hi Gun77 !
As i knew, ODBC Generic Connectivity Agent is an API which use for connect other RDBMS. Don't care cost because it's free.
In other way, u can use Oracle Generic Connectivity Agent to any DB (SQL server, MySQL,…)
Download the orajdbclink_o2a.zip (oracle-to-any) file:
http://sourceforge.net/project/showfiles.php?group_id=205664
u can see detail in this link:

Hope good for you!

Transfer data from two oracle version to one sql server 2005

Hi,
I have two database servers on different machines. They are
1) Oracle 8.1.7.4
2) Oracle 7.3.1.4
I have to create agents which can transfer tables from these two databases to one machine having sql server 2005 database.
Please tell me what are the options. What drivers i need to install on machine having sql server 2005 so that i can transfer data from both oracle versions.
Thanks
Rajneesh.

Your Oracle databases are so old you might want to look around and see if you can find dinosaur bones near by.
Given the differences in data types between Oracle and SQL Server I'd suggest you start off by dumping the data into delimited ASCII files and then loading it using whichever SQL Server tool you wish.

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
Shanil

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

Read Oracle 10g Tables to SQL Server 2012

Hi all,
I have Oracle 10g on an XP machine, and use the 'Oracle in OraDB10g_home1' driver to read the data. I have another Windows Server 2008 R2 machine on the same network, with SQL Server 2012 on it. What is the best way to read Oracle Tables in SQL Server? Can I setup an ODBC link from my Windows Server machine to the Oracle Database (which would require me to download an Oracle ODBC driver)? Or is the best way to export the required tables from Oracle (e.g. into csv format) and import them into SQL?
Thanking you in advance,
Imelda.
