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

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.

You could create a linked server. Install the Oracle client on the server with SQL Server 2005, setup the TNS to your Oracle databases, create the linked server and then grab the data that way. There are migration tools as well but if the database is small in size I found linked servers to work and give me better control over the migration. This assumes that the database is not very large. If it is really large a migration tool might be a better option.

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.

OBIEE 11g - Combine data from two Oracle tables

Good day!
I tried to combine data from two Oracle tables as fact data, but it doesn't work.
My steps: I created SCOTT.EMP2 table from SCOTT.EMP table, update EMPNO and ENAME values of EMP2 table to distinguish data of my tables. Then I imported physical tables DEPT, EMP and EMP2 to BIEE 11g, created joins DEPT-EMP and DEPT-EMP2 in physical diagram. Then I dragged DEPT and EMP tables to BMM, and EMP2 table to EMP as second LTS. In Content tab for EMP and EMP2 I checked "This source should be combined with other sources at this level" checkboxes. Then I renamed logical tables EMP and DEPT to Employees and Departments and dragged them to Presentation area. In Answers I created Analysis with columns DNAME and ENAME.
The problem is that data on results tab is only from one physical table EMP or EMP2 (depending on the order of sources EMP and EMP2 of LT Employees) and not from both.
Can anybody help? Am I missed something?
Al.

Hi Al,
I think you have to define the content of the LTS.
http://download.oracle.com/docs/cd/E12096_01/books/admintool/admintool_BusModSetup16.html
You have to specify the content of the different fragments.
http://download.oracle.com/docs/cd/E12096_01/books/admintool/admintool_SetUpAggNav3.html#wp1005333
Maybe you have to add an additional column 'Source' ('EMP1', 'EMP2')
Good Luck,

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.

Two oracle versions on one client

Hello
I installed Oracle7 and Oracle8 Client together on the same machine.
So far it works well. But when I want to open one of my ODBC Drivers, I4m getting the following error:
ODBCADM caused a general protection fault in KRNL386.exe at 0001:243F.
Is it possible, that this is because of the two Oracle versions?
Or does anybody have another idea?
Thanks, Anja

Hi,
Like Kamal said, no problem. You can have 2 tnsnames.ora, one in 8i (where you declare 8i databases), and one in 10g (where you declare 10g databases).
To connect to 8i, set ORACLE_HOME to 8i directory and use 8i sqlplus.
To connect to 10g, set ORACLE_HOME to 10g directory and use 10g sqlplus.

Two Oracle databases on one AIX Server - Note working, Pls Help

Dear Friends,
I have installed Two SAP systems with Two Oracle Databases on one AIX machine, The Installation of both the systems went fine without any errors, and also i have been able to login to both the systems seperately. (that means i cant start both the systems at a time, its one at a time)
But the problem is of the Oracle Listener, i am not able to start both the systems with single Oracle Listener processes(tnslistener). I tried all the possible scenarios as mentioned in note 98252 but nothing seems to be of any use so far.
the thing is i can start either one of the SAP Systems, But my objective is to start both the SAP Systems with one listener processes (LISTENER) and one listener port (1527)
Or
you can say i am also ready to keep two different listeners for TWO seperate Oracle databases, I tried doing so as per one of the sap notes in which you have to keep different names of listener and different numbers for listener port for second ORACLE database. I tried doing exactly mentioned in the note but yet unsuccessful...
Now i am completely lost as what is to be done since its critical i want you to immediately look into it and suggest me the appropriate solution so that i can set up both of my DEVELOPMENT and QUALITY system running...
To troubleshoot this if you require anything from my side then please feel free to ask me since our functional consultants have to soon start working on the SAP systems.
Regards
Ayush

The note you specified talk about 2 database instances not 2 databases... (I was starting to wonder how you deploy 2 databases), you can have multiple database instances on a DB. The note also give you detailed explanation of the configuration of listener.ora
Now, if this is the case and you have installed 2 instances (not databases) on the same host and configured the listener according to the note, then you should be able to call R3trans -d from both SID's.. if the R3trans fails please post the contents of trans.log here.
the thing is i can start either one of the SAP Systems, But my objective is to start both the SAP Systems with one listener processes (LISTENER) and one listener port (1527)
Then, the configuration of your listener.ora file must be incorrect.

Juan

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...

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!
Edited by: Gun77 on 2009/08/12 8:48 AM

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:
http://duykhanh.wordpress.com/2009/08/05/oracle-dblink-to-any-db-sql-server-mysql%E2%80%A6/
Hope good for you!

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.
Regards,
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...

How do I transfer data from two computers onto my new mac?

I recently bought a new macbook pro with retina display after owning an iBook G4 and a powermac for 7 years but I now want to transfer the data from both of my computers (which both only have one account) onto my new computer. I'm wondering if it is possible to transfer the data from both of the computers onto my new one and if so how. Another issue is that my ibook had recently broken but the only issue was the ram was not working so I had the data recovered and put on an external hard drive so now what was on my ibook is now on an external hard drive. I really want to know if I can still transfer both computers onto my new one or if I can only transfer one of the computers onto my new one and I have to transfer the other one manually. Any ideas?

Migrating is simple and complicated at the same time, in your case simple to transfer files (e.g. films, pictures, docs...), and difficult for settings and all hidden stuff. My piece of advice is to use iBackup (grapefruit.ch) for system settings, which does not take too much, and simple drag-and-drop from older macs unto the new one. I would use firewire, as Retina does not this port, try to purchase a FW-to-ThB adapter, it may be worth having it. Connect the new mac to the old ones one after another, and restart the old ones in target mode (press T after chime), they will turn intro external drives, and may easily transfer anything.
If you are not familiar with iBackup, perhaps it is better to Migration Assistant, I do hope it works with older Mac OS. Note that, used after settings a new mac, it will create new users for the transfered data. The advantage is, they will transfer files and settings, but perhaps more than you really need.
Ort, as BGreg says, manual transfer of all files, this may prove slower, but you may have full control of all operations.

Installing two Oracle Version in One Windows[/b]

Hi Guys
I want to know how to install two different versions of Oracle in One Windows Under Different Homes.

A guess is that this is due to the earlier 8.1.7.x ODBC drivers did not support multiple homes (max one ODBC version per PC - ugh!).
If you can't skip this error, try to uninstall 9i ODBC, install 8i, upgrade 8i driver and then reinstall 9i ODBC (in the right home)... I guess a better way would be to do this in the correct order on a clean PC (to avoid registry messup as much as possible).

HTTP post data from the Oracle database to another web server

Hi ,
I have searched the forum and the net on this. And yes I have followed the links
http://awads.net/wp/2005/11/30/http-post-from-inside-oracle/
http://manib.wordpress.com/2007/12/03/utl_http/
and Eddie Awad's Blog on the same topic. I was successful in calling the servlet but I keep getting errors.
I am using Oracle 10 g and My servlet is part of a ADF BC JSF application.
My requirement is that I have blob table in another DB and our Oracle Forms application based on another DB has to view the documents . Viewing blobs over dblinks is not possible. So Option 1 is to call a procedure passing the doc_blob_id parameter and call the web server passing the parameters.
The errors I am getting is:
First the parameters passed returned null. and
2. Since my servlet directly downloads the document on the response outputStream, gives this error.
'com.evermind.server.http.HttpIOException: An established connection was aborted by the software in your host machine'
Any help please. I am running out of time.
Thanks

You can use remote LOBs via a database link. However, you cannot use a local LOB variable (called a LOB <i>locator</i>) to reference a remote LOB. A LOB variable/locator is a pointer - that pointer cannot reference a LOB that resides on a remote server. So simply do not use a LOB variable locally as it cannot reference a remote LOB.
Instead provide a remote interface that can deal with that LOB remotely, dereference that pointer on the remote system, and pass the actual contents being pointed at, to the local database.
The following demonstrates the basic approach. How one designs and implements the actual remote interface, need to be decided taking existing requirements into consideration. I simply used a very basic wrapper function.

Irrespective of how you do it, selecting that LOB column from that table will require a 100GB of data to be transferred from the database to your client.
So you need to decide WHY you want the LOB on the client (which will be the local PL/SQL code in case of dealing with a LOB on a remote database)? Do you need the entire LOB? Do you need a specific piece from it? Do you need the database to first parse that LOB into a more structured data struct and then pass specific information from that struct to you? Etc.
The bottom line however is that you can use remote LOBs. Simply that you cannot use a local pointer variable to point and dereference a remote LOB.

Need help setting up DB Link from my Oracle 11g XE to SQL Server.

Hi,
I'm trying to create a DB Link from my Oracle 11g Express Edition in a Windows XP machine to an SQL Server. Here are the steps I've done so far.
1. Created and setup an ODBC Connection for the SQL Server DB. Named it SQLSERVER. Windows Authenticated.
2. Modified listener.ora. See below.
SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = extproc)
    (SID_DESC =
      (SID_NAME = SQLSERVER)
      (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
      (PROGRAM = hsodbc)
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
DEFAULT_SERVICE_LISTENER = (XE)3. Modified tnsnames.ora. See below.
XE =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
SQLSERVER =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT=1521))
    (CONNECT_DATA =
      (SID = SQLSERVER)
(HS = OK)
)4. Copied C:\oraclexe\app\oracle\product\11.2.0\server\hs\admin\initdg4odbc.ora to C:\oraclexe\app\oracle\product\11.2.0\server\hs\admin\initSQLSERVER.ora and modified it. See below.
# This is a sample agent init file that contains the HS parameters that are
# needed for the Database Gateway for ODBC
# HS init parameters
HS_FDS_CONNECT_INFO = SQLSERVER
HS_FDS_TRACE_LEVEL = off
# Environment variables required for the non-Oracle system
#set <envvar>=<value>5. Restarted listener.

Here's more information on the machines.
Machine where the Oracle Database 11g Express Edition: IP Address is 10.162.128.67
Machine where the SQL Server database: IP Address is 142.120.51.30.
I've modified the tnsnames.ora to the following:
XE =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.162.128.67)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
SQLSERVER =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 142.120.51.30)(PORT=1433))
    (CONNECT_DATA =
      (SID = SQLSERVER)
(HS = OK)
)But now I'm getting the following error:
