Data Migration Oracle 7.16 To SQL Server 2000
Aug 22, 2006
Hi,
I have been asked to look at optimising a Data Migration Strategy for one of our clients. I am quite new to Data Migration (I'm actually a system designer!).
The migration is from a legacy Oracle 7.16 Db to a SQL Server 2000 environment.
The legacy Db has some large tables - 30 Million+ rows
Table/column Mapping is 1:1
At present we are using DTS to import into the SQL environment.
My question is: Is there any way to leverage the Oracle 7.16 export to speed up the migration process?
Any advice would be appreciated.
Many thanks
Mike

Hi,
I'm new to SSIS.
I want to migrate data from Oracle Database to SQL Server 2005 by using SSIS Package. Client wants to migrate just data not schema. Schema is already there for SQL Server, generated through script.
I tried to migrate the data by using import-export wizard in SSIS. But, its asking for creating new tables when migrating data.
I want to migrate data in existing tables, without dropping already existed tables or creating new tables.
any suggestions ?
Regards,
Khurram

Hi all,I am using the Oracle Workbench for migrating my DB currently on SqlServer 2000 to Oracle 9i. During the migration the following happensSELECT @tBaseTable = tBaseTable, @tDBColumnName = tDBColumnNameFROM tblColumnMain WITH (NOLOCK) left join tblCustomField WITH(NOLOCK) on aColumnID = nColumnIDWHERE aColumnID = @nPropertyIDgets converted toSELECT tBaseTable, tDBColumnNameINTOSPROC_PROPDATA.tBaseTable, SPROC_PROPDATA.tDBColumnName, FROMsa.tblColumnMain, sa.tblCustomFieldWHERE (aColumnID = nColumnID) AND (aColumnID =SPROC_PROPDATA.nPropertyID_);and gives the warning that complex outer joins maynot be reliablyconvertedOn the other hand the following codeselect @keyid = a.keyID, @pubs=b.pubs fromssd1 a left outer join ssd2 b on a.l_name = b.l_namewhere b.l_name = @namemigrates perfectly to Oracle asSELECT a.keyID, b.pubsINTO SPROC_JOINTEST8.keyid, SPROC_JOINTEST8.pubsFROM ssdash.ssd1 a, ssdash.ssd2 bWHERE (a.l_name = b.l_name(+)) AND(b.l_name = SPROC_JOINTEST8.name);with the same warning ...Could anyone enlighten me as to what exactly is the difference betweenthese 2 above cases.Also the migration bench seems to be removing nolocks and such stuff allaround. Any workaround for this is also needed.ssDash--Posted via http://dbforums.com

OK I migrated a DTS package from MS SQL 2000 to MS SQL 2005 64-bit SSIS. OK so I fixed a problem with a Double Global Variable... Now I am stuck at a connection to Oracle and it returning data... Here is the error message:
[Execute SQL Task] Error: An error occurred while assigning a value to variable "Remedy_Count": "Unsupported data type on result set binding 0.".
My SQL Statement is this:
SELECT COUNT(*) AS Expr1
FROM DB.MYTABLE
When I run it from the Query Builder it returned this:
EXPR1 = 2983
Here are some details from the General Page on the Execute SQL Task
ResultSet - Single row
ConnectionType - OLE DB
Connection - Oracle Provider for OLE DB
SQLSourceType - Direct input
BypassPrepare - True
In the Result Set I have The following:
Result Name - Variable Name
0 - Remedy_Count
So... what can I do to fix this. I have the Remedy_Count set as a:
EvaluateAsExpression - False
Value - 2414
ValueType - Double
I have tried setting the ValueType to Object and other things... Same error... I read some where about how SSIS has issues when Oracle returns a Numeric type data. Can someone help me with this? Anything you all can tell me would be great.

Hi all
Does SQL Server has any equivalent of Oracle (PL/SQL) PRAGMA AUTONOMOUS_TRANSACTION ????
I am in a process of migrating Oracle database to SQL Server. I am facing trouble in the above mentioned thing, as I cannot compromise by not putting it.
Thanks in advance

Has anyone ever tried to use this free software to migrate an old ORACLE 8.1.7 database to SQL Server 2005? I was just wondering if there were any "gotchas" I should be aware of before hand.
Thanks,

I selected my source Oracle database and my target SQL Server database. I click the convert SQL button and it takes about 20 minutes to convert everything. Then what? The Migrate Data button is greyed out. I configured the linked server as is outlined in the instructions. The "Migrate Data" button is always greyed out.
I need to get this working soon so that I can convince the management team that moving to SQL Server is the way to go.
Thanks.

I'm trying to make the business case to move our business databases to SQL Server 2005 from Oracle 9i. The SQL Server Migration Assistant for Oracle will be absolutely necessary for this to happen. However, I am unable to launch the assistant. It tells me I have an old version of java installed - but I don't. It is a new XP machine and I downloaded and installed j2sdk-1_4_2_12-windows-i586-p.exe which did not help (I rebooted). Why does it think I have an old version and how can I get this assistant working.
Any help would be much appreciated.

Hello there
I have a customer that wants to start using SQL Server 7.0 instead of Oracle, but they have a lot of Oracle applications (made in Developer 2000 and Forms). Due to the big effort needed to convert those applications (to Visual Basic), they want to be able somehow to migrate only data from Oracle to SQL Server, and then use some tool that will allow them to use the same applications with the SQL Server 7.0 engine.
I found on the "SQL Server Developer's Kit" a document describing the process of migrating data and applications from Oracle to SQL Server. There is a mention to an Oracle tool called "Oracle Gateway to SQL Server" that will translate calls received by the Oracle engine to the SQL Server engine, but this approach will still require the existence of Oracle servers (which is the thing the customer no longer wants).
The second option mentioned on that document, and the one that seems more attractive, is the use of Oracle "Open Client Adapter" (OCA) that will allow Developer 2000 applications to communicate directly to SQL Server via ODBC. However, I have been unable to find (on the Oracle site) any documentation regarding this tool.
Has anynoe heard or used such tool (OCA) ? Any comments, tips, drawbacks, experience you could share ? Any other idea on how a thing like that could be accomplished ? Perhaps a third-party application that can act as a gateway between the Forms app and ODBC/SQL Server, or that will be able to generate VB code from a Developer 2000/Forms app...
Any help will be appreciated.
Please respond directly to me, as I am not a member of the distribution list.

Hi all. I'll say from the get go that I'm no SQL guru. I'm primarily a web dev who has been given the data jobs kind of by default so I'm definitely no DBA.
Anyway, having established my noobness, I have encountered an issue. The employer recently decided to upgrade our databases from 2000 to 2005 and I have been tasked to migrate the data from old to new. I have discovered the Import/Export Wizard and got it to move all the data in a dev database we use...but there was one problem. It seems that the tables in 2000 that had columns designated as identity columns do not have the identity attribute when they arrive in 2005.
I haven't figured a way to alter them to give them that attribute once they're in 2005 so I'm wondering if there's something I can do/change in the import process that would retain the identity property of the columns if I were to re-import them.
This is my first migration attempt so dumping it and starting over is no great loss...but any help would be most appreciated.

I am trying to import data from SQL 2000 to SQL 2005
The Data schemas are the same in both (tables, relationships, key and triggers).
Using the wizard I am trying to import data from SQL 2000 to SQL 2005. The issue I face is to manage the Idenity columns. I do not want the identity values from the SQL 2000 DB which may be at say 5000, instead I want to use the identity values from the SQL 2005 database which will problably start at 1
Is there a way to do this, should I use a custom query instead of a direct table dump. If using a custom query do I need to just specify a Select query or does it have to be a specific "INSERT INTO Table ..." type query
If I do import the data directly with Identity "ON" how can I advance the identity column value to current +1 on the SQL 2005 table.
Thanks

I€™m currently evaluating SQL Server 2005 to what advantages there would be to upgrading from SQL Server 2000. Our existing systems make much use of DTS so it critical for us to be able to run SQL Server 2000 DTS packages in SQL Server 2005. Having installed the Enterprise SQL Server 2005 CTP successfully on a new Windows 2003 server and following the advice to install Legacy Components I find the Migration Wizard (under Legacy> Data Transformation Services) fails with the following error after entering source and target dialogs: This wizard will close because it encountered the following error: Additional Information: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index (mscorlib) Also when trying to open a structured storage DTS file I incur another error: Unable to load DTS 2000 Runtime. This component may have not been installed (Microsoft.SqlServer.DtsObjectExplorerUI) This error seems to imply that the DTS 2000 Runtime needs installing. Can this component be downloaded and installed separately?

Hello,
I have a client that is moving their web ap (which has already been developed) from one host to their own servers. The problem is that they don't have MS SQL Server 2000, but they have MSDE. All the code is already writen to work with SQL SERVER 2000.
I have a couple of questions:
1. Can I safely assume that all this code will work with MSDE and all I have to change is the connection string? For example:
SqlConnection myConn = new SqlConnection(connstring);
In other words, can I still use the SqlClient classes to work with MSDE, or will I have to modify the code?
2. Will it be a problem creating the tables and migrating the data from SQL SERVER to MSDE? Can I use Enterprise Manager to do this?
3. I never had to remotely (or even locally) connect to a MSDE database alone, I always develop with a SQL Server db. Can I use a similar connection string for the MSDE database? Do I have to create a data provider on the local machine? Can you give me an example of a MSDE connection string?

Hi Friends,
I am doing my final semester project. It is a migration tool that converts the DB2 PL dialect into MSSQL Server's T-SQL dialect.
I am in need of sample DB2 PL files(procedures, UDFs, triggers) for testing the tool. Please point out me to some DB2 files repository links or if you have some files, please give me the same. I will use this only for testing purposes.
Appreciate your help.
Thanks & Regards,

OK so I'm just the Network Admin here, but our DBA's are off doing other stuff. So I thought I may inquire here about how the easiest way to migrate from SQL Server 2000 to 2005? The first server I'd like to migrate is just databases with a few users, no DTS packages or anything like that... The only problem is that there are several hundred db's, so moving them one at a time is not an option. Has anyone here had successful experience with doing this? Thanks in advance for your help!

I have a fairly large web application that was built with SQL Server 2000 and .NET 1.1. We're planning on moving to .NET 2.0 eventually, but there's a lot of work to be done before that happens. In the short term, we're looking to purchase a new database server and would like to upgrade to SQL Server 2005 at the same time. Is it as simple as recreating our databases on this new system and changing the connection string, or are there other gotchas? As far as what we're doing with SQL Server 2000, it's really nothing more than tables, views, and stored procedures. Thanks in advance for any advice.

Has anyone had any experience with the Oracle Migration Workbench? or using DTS to migrate MS SQL to Oracle? The Migration Workbench seems to work great but it is having parsing issues with some of the syntax in our triggers and procs (roughly 1025 of them). Are there other ways of handling these errors other than manually cleaning them up?
Thanks in advance.
