How to migrate an existing Microsoft SSIS deployment if it is decided to replace SQL Server with an Oracle database?

Hi Oracle Gurus!
Currently, I am designing an ETL solution that transforms and loads a lot of data from flat files and sends it to an SQL Server 2008 R2 database for storage. However, at a future point of time, it may be decided to add or even replace SQL Server with an Oracle 11g database.
Currently, I am writing script transforms in C# to dynamically generate SSIS packages to tansform and load the data into SQL Server. But considering that in future, an Oracle 11g or 12c database might be added to, or replace the SQL Server database, how do I make my script transforms (or whatever else I am developing currently for SQL Server) reusable to the extent possible?
Or more precisely, what steps do I take, from an Oracle point of view, to ensure that any future migration of data to an Oracle database would be smooth to the extent possible?
Looking up to my Oracle Gurus for enlightenment in this matter!

When you're writing your on C# code to load data into the SQL Server you have to modify the routines so that they will work with Oracle.
One approach is to use the extproc agent which would allow you to directly call external programs with all the logic in it to perform the load of your files and to put the data into the Oracle database. Another option would be to use utl_file package (or equivalents) which will allow you to open external files from your Oracle database and to directly read its content and then to pass it to the related tables.

How to Migrate Stored procedure on Sql server 2008 to Oracle Database

Guys, I need help vey badly as I am new in this field.

Any method (no problem)
Please, help me or give me any reference as I don't know which keyword is differ in both database.
Thanks in advance

Hi,
You could the free Oracle SQL*Developer to do this.
There is information and a download link here -
Oracle SQL Developer</title><meta name="Title" content="Oracle SQL Developer"><meta n…
and information on using it for migrations here -
http://www.oracle.com/technetwork/database/migration/index-084442.html
You could use it in 2 ways -
1. Go through a migration but just pull the stored procedure code from the file created after you generate the SQL from the SQL*Server database
2. Use the scratch editor accessed from -
- Tools - Migration - Scratch Editor
and paste the SQL*Server stored procedure code into the window and it will convert it to Oracle code. The tool is very good but may have problems if you have very complicated procedures that use SQL*Server specific utilities.

How to Migrate the Existing Content

Hi every1,
I want to know how to Migrate the existing content in Interwoven to new Content Management system
Thanks & Regards
Vasu

Hi Vasu,
as said, I don't know Interwoven in detail. But if you would get the Interwoven Business Package, maybe you could get some insight how to access Interwoven content per API (at least, Interwoven <i>has</i> a Java API, see http://blogs.ittoolbox.com/km/content/archives/005150.asp for example; but I would ask Interwoven or within some Interwoven forum for the details, and on this site for the details of SAP KM API... ).
Hope it helps

[Forum FAQ] How to get SSIS packages XML definition which are stored in SQL Server Integration Services instance

Introduction
Integration Services gives you the ability to import and export packages, and by doing this change the storage format and location of packages. But after import packages into package store, how can we get the package XML definition?
Solution
As we know, SSIS packages are stored in msdb using existing SSIS storage table([msdb].[dbo].[sysssispackages]). The “packagedata” column store the actual SSIS package with Image data type. In order to get the package XML definition, we need to convert “packagedata”
column through Varbinary to XML. You can refer to the following steps:
Using the following query to get package GUID:
SELECT [name],
[id]
FROM [msdb].[dbo].[sysssispackages]
Using the following query to convert packagedata column to XML: SELECT id, CAST(CAST(packagedata AS VARBINARY(MAX)) AS XML) PackageDataXML
FROM [msdb].[dbo].[sysssispackages]
WHERE id= 'ABB264CC-A082-40D6-AEC4-DBF17FA057B2'
More Information
sysssispackages (Transact-SQL):
http://msdn.microsoft.com/en-us/library/ms181582.aspx
Applies to
SQL Server 2005
SQL Server 2008
SQL Server 2008R2
SQL Server 2012

How to Migrate my database from SQL Server 2000 to Oracle

I want to transfer my database from SQL Server 2000 to Oracle, Can I do this without using Oracle Migration Workbench ??
Please help me.
Thanks in advance
Vicky... :-)

Do you have a good technical reason for not wanting to use the Migration Workbench?
Given that it's free and does a hell of a lot of the work for you, why wouldn't you use it?
Other than that, I would say you would be on your own...

DB Migration from MS SQL Server 2005 to Oracle 9i

Hi Guys
I want to migrate the data from Microsoft SQL Server 2005 to Oracle 9i.
Could ou please suggest me the how to proceed.
I can simply extract the das in CSV format as their are Foreign key , Primary key concept is there. So what will be the best way to proceed ....
regards
Macky

Macky,
In the coming months we will add support for SQL Server 2005 to the Oracle Migration Workbench. See our statement of direction on OTN for more details.
If you have extracted the data into a csv file format, you could construct a SQL Loader control file to load this data, assuming you have already created the table on the Oracle side.

Copy table from Ms SQL Server 2005 to Oracle with SSIS package

Hi all
I am witting an SSIS package to copy 2 tables from Ms SQL Server 2005 to an Oracle 10g database.
Problem: I can only see the Microsoft OLDB Provider for Oracle and it is too slow. How can I use the Oracle ODBC in aMs SQL Server 2005 or building a .net SSIS package.
thanks

Yes I am able to see the driver on the Data Source (ODBC), I also created a connection to the Oracle database. The problem in Ms SQL Server 2005 is that the ODBC connection I created is not listed. None of the lo local connections are listed, only Microsoft OLEDB connections

Siebel database migration from Sql Server 2005 to Oracle 11g RAC.

Hi Naveen,
We would like to migrate our Siebel database from Sql Server 2005 to Oracle 11g RAC. Can you suggest the best way to do that ?You will need much more which suggestions.
You will need a Siebel professional which has done this type of migration. Migrating the Database is not a task so hard, after migrating your environment should be functional and healthy it is usually the task problematic.
The hardware can be changed if needed. Can you please suggest the best approach ?We can recommend the minimum recommended, but this documentation already does, you need to do a analysis on your environment and ask a vendor Siebel tell the which is recommended for you and how to find the best "number" for you, in your case is very hard because everything changes.

Migration of SAP Business Objects BI Platform 4.1 from Windows(OS), SQL Server(DB) to AIX(OS) and Oracle(DB).

Dear All,
I have SAP Business Objects BI Platform 4.1 running on window servers and sql server database. We want to migrate this to AIX and oracle.
Can you please share what should be the best approach to carry on this migration?
Regards,
Asleh

Hi Mohammed,
Regarding your Query below is the suggestion:
Step I: Preparing for moving BOBJ application from Windows to AIX
There are some tasks that you need to perform:
To configure the existing deployment
Perform inventory and cleanup, to ensure that only the required content is moved.
Run the Repository Diagnostic Tool to detect any inconsistencies between the File Repository and the CMS repository. The upgrade management tool will not run successfully if there are inconsistencies between the File Repository and the CMS repository.
Identify any content that the upgrade management tool can't upgrade, along with the process required to upgrade that content. There is some content like Voyager Workspaces or Desktop Intelligence documents that require manual intervention before running the upgrade management tool.
Back up existing repositories, including the system database and the Input and Output File Repository Servers.
Back up custom web applications, HTML pages, and scripts in your existing deployment.
To configure the planned BI 4.x deployment
Setup and configure the Middleware and ODBC connections.
Ensure that your machines meet the deployment system's requirements, you can find information about the supported platforms in the Platform Availability Matrix (PAM) http://service.sap.com/support -> Help and Support -> SAP BusinessObjects Support -> Documentation -> Supported Platform s/PARs -> SAP BusinessObjects BI 4.x
Step II:
You can use database backup & FRS backup (Offline) in new environment (AIX) to deploy BOBJ 4.x Version
Take the help of DBA to move CMS & AUDIT database backup from SQL Server (Windows) to Oracle (AIX)
Test the Universe,reports, Check the rights
Step III:
If you are configured any SSO then make sure that same configuration is deployed in new environment (AIX).
Test the user SSO in new environment (AIX).
Or
You can also use Promotion manager to move the contenet from Windows (Business Objects Application) to UNIX (Business Objects Application)
Only prerequisite is Business Objects Application version should be same.
You can copy content only 50 Object at a time in One Job
FRS Offline backup is required.
Necessary files regarding custom web applications, HTML pages, and scripts in your existing deployment.
Please refer the below KBA for more details

Migration From SQL Server 2005 to Oracle DB through Oracle SQ Dev Problem

Hi all,
we are trying to do a full Migration from MS SQL Server 2005 to Oracle DB 9.2 i
we are using Oracle SQL Developer V 1.5.3,
the capturing of the DB and the conversion to the oracle model completed succefully
however when we try to generate the scripts from the converted model
the script generation hangs on a sequence and no further progress is made (the script generation pop up keeps still on a certain sequence displaying its name, and thats it )
no error messages are displayed,
how can we know the reason for this? or atleast find a log for whats happening...
any suggestions?
Thank you

Hi,
migrating a sequence shouldn't make a problem. I did a quick test. I created this table in SQL Server:
create table test_seq (col1 int identity(1,1),col2 char(1))
Then I captured the table, converted the table and generated the script. There was no problem.
CREATE SEQUENCE succeeded.
CREATE TABLE succeeded.
Connected
TRIGGER test_seq_col1_TRG Compiled.
As you see, applying the script was also successful.
I am using Oracle RDBMS 11g, I don't know whether this makes a difference. Do you have any 11g instance available to test it?
Can you show me one of the sequences that are causing the hang? Is the CREATE SEQUENCE statement already in the generated script, or not? Your table is for sure more complex than my simple example.
Regards,
Wolfgang

Error when using Oracle Migration WorkBench (Sql Server 2k to Oracle 8i)

I'm trying to migrate a Sql Server 2k database to an Oracle 8i schema using OMWB. After using BCP to collect metadata information on the source database, I tried to capture the source data model and got a "Capture aborted" message on the progress screen (even though then it appears a dialog window reporting "0 errors and 0 warnings", funny!).

Does SSIS guarantee that it loads the data into SQL Server in the same order as it is in Excel

Hi,
We are trying to load several Excel files into SQL Server SSIS and we need to save the data in the database in the same order as it is in Excel..
My question is, Does SSIS guarantee that it loads the data into SQL Server in the same order as it is in Excel. If so, we will add a sequence to ensure we have the order.
Please advise.
Thanks & Regards,
Dhanumjay

Thanks for your response.
If it is one file then we can add an index column, but we have to load hundreds of files.
How adding an index/key column to the table works unless SSIS picks and loads the data in the table in the same order as it is in Excel?
Just to explain my question better,
If excel has three rows {a,b},{c,d},{e,f}, does SSIS ensure it loads the data in the same order in a table.
Thanks.

Migrating SQL Server DB to Oracle DB - probably EASY answer

I completed the tutorial on migrating SQL Server DB to Oracle. When I try on my own database, it all migrated well except anything containing a datetime. When I run the oracle_ctl.bat file and view any of the log files, I see Record 1: Rejected - Error on table DBO_RIVERSIDEDB_NCWCD_TEST.TS6HOUR_TAIN, column DATE_TIME.
ORA-01843: not a valid month. Do I need to change the first line of the file set NLS_DATE_FORMAT=Mon dd YYYY HH:mi:ssAM ? In the .dat file created from the unload_script.bat, the data starts out 1275<EOFD>2007-05-11 00:00:00.000<EOFD>74.900000000000006<EOFD><EOFD><EORD>1275<EOFD>. So my questions is about the date_format - is that the same for all SQL Server databases or do I need to enter something based on MY database? I am definitely a newbie so this is probably a super easy question. Thanks so much for any help!

Hello,
There are two different date format in SQL Server.
1] DateTime : 2010-08-03 12:48:15.170
2] SmallDateTime: 2010-08-03 12:48:00
Both the date will be inserted in Oracle Date column.
Is there any automated way to generate datamove script to tackle these differences? I've around 200 tables to be migrated and there may be many such cases.
The issue with Oracle SQL Developer setting i.e. Tools >Preferences> (Under) Migration> Data Move Option, there are two masks we can specify, one for Date Mask and other for Timestamp. How can I set both of these for converting data into Date, not in timestamp.
Below is my .CTL file, none of below fields are timestamp, but since incoming data in in timestamp format, it is applying timestamp mask and eventually failing to insert data into table
load data
infile '[PARTSORDER].dat'
"str '<EORD>'"
into table admin.PARTSORDER
fields terminated by '<EOFD>'
trailing nullcols
ORDERID ,
GenDate "TO_TIMESTAMP(:GenDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",
Status "DECODE(:Status, CHR(00), ' ', :Status)",
StatusBy ,
StatusDate "TO_TIMESTAMP(:StatusDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",

CompletedBy "DECODE(:CompletedBy, CHR(00), ' ', :CompletedBy)",
CompletedDate "TO_TIMESTAMP(:CompletedDate, 'YYYY-MM-DD.HH24.MI.SS.ff3')",
ORDERType "DECODE(:ORDERType, CHR(00), ' ', :ORDERType)",
RMAID ,
RMANumber "DECODE(:RMANumber, CHR(00), ' ', :RMANumber)",
BackOrdered ,
XORDERID ,
PARTSORDERSENT "DECODE(:PARTSORDERSENT, CHR(00), ' ', :PARTSORDERSENT)",

Migration from SQL Server 2005 to Oracle 10g

Dear buddies,
I need to migrate my tables with data from SQL Server 2005 to Oracle 10g. How can I do it in the best possible way?
Please guide me.
Nith

Nith,
I doubt if there is one best practice that can cover all cases of migrating data from sql server to Oracle. l generally find various factors case-by-case that make me chose one approach over the other. Without considering the business case and environment specific factors, some of the things I would like to know would be: The data types of the tables columns, table sizes, number of tables and if this is a one time process or a recurring process.
One of the easiest (some times rather pesky) process would be:
-Dump source data (Sql Server data) into flat files, csv or any preferred format
-Setup a set of staging set of tables in the destination DB (Oracle in your case). You can setup the stage tables to enforce data-types, value sets and even some level of integrity constraints or any data logic or what ever you would like to filter out. Load the flat file data into a set of Oracle stage tables (Sql*Loader would be a good candidate)
-You can always move data from these stage tables to you application tables
You can script this whole process to run as batch or on demand or how ever you would like.
I am sure you can google and find a bunch of proprietary as well as open source tools to do the same with little to a lot of work.
good luck!
