I want to do a data transfer but i am not sure how ..from oracle to sql server.

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,
Robert

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 can connect to my Oracle database and I can connect to my SQL Server database. But the "Convert Schema" button stays disabled. What am I doing wrong? Anyone have experience using this tool?

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.

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,
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

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.

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

We are going away from a 2003 Windows Server OS with SQL Server 2008 R2 to a 2012 Windows Server with 2012 SQL Server. Both the distributor and subscriber resides on 2003 Windows Server and the focus will be to migrate those databases to the 2012 SQL Server.
 We would also like to avoid sending down a new snapshot due to logic in the replication process (major headache to clean up data).  what's the best approach in moving the distributor and subscriber databases without having to run a snapshot? Â
In theory and needs testing:
1. Work with business users to get downtime
2. Stop sql apply so no new changes are going to the Oracle publisher database
3. Remove subscription, publication and distributor from current replication
4. Oracle DBA to clear out replication related objects - fresh clean slate
5. Use log shipping to apply last t-log and restore db with Keep_Replication
6. Set up new distribution, publication (keep existing object unchanged), and subscriber (without initialization) Will this work?

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.

It is posible with Entreprise Library to use the SAME QUERY, by example,
"Select isnull(Val,33) from calculs where Col1 is not null" (specific for Sql Server)
to select data from Oracle too ? or the only way is to use specific stored procedures (queries)
wtitten in 2 ways : for Oracle and for Sql Server?

Hi--
I am running SQL Server 2005 on Win2k3:
Microsoft SQL Server Management Studio 9.00.2047.00
Microsoft Analysis Services Client Tools 2005.090.2047.00
Microsoft Data Access Components (MDAC) 2000.086.1830.00 (srv03_sp1_rtm.050324-1447)
Microsoft MSXML 2.6 3.0 4.0 6.0
Microsoft Internet Explorer 6.0.3790.1830
Microsoft .NET Framework 2.0.50727.42
Operating System 5.2.3790
I have the OraOLEDB.Oracle provider installed to the (C:oraclexe) directory.
I am having problems querying from linked oracle server. When i setup oracle as a linked server and purposely enter an incorrect password the query i run tells me i have an incorrect password. So it at least knows that. when i set the correct password and run a query I get this error:
(i replaced the real server name with "someServer".)
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer" reported an error. The provider did not give any information about the error.
Msg 7303, Level 16, State 1, Line 1
Cannot initialize the data source object of OLE DB provider "OraOLEDB.Oracle" for linked server "SomeServer".
This is how I set up my Linked server:
Provider: "Oracle Provider for OLE DB"
Product Name: SomeServer
Data Source: SomeServer
Provider String: "Provider=OraOLEDB.Oracle;Data Source=SomeServer;User Id=MyLogin;Password=MyPassword"
The query I run is:
Select * from [Someserver].[schema or database]..[tbl_name]
Any help??? What am i missing?

I am using execute sql task to run a stored procedure in oracle database which returns a resultset. This works. Now I need to send the ouput to a destination table in a sql database. Should I use for each loop to pick the resultset and insert it into the destination one by one (which I dont think is a great idea) or is there a better way to accomplish this task (in data flow task) ?
When I use dataflow task instead of execute sql task, the main issue is I am not able to see the output columns when I execute an oracle stored procedure, but when I see the preview I can see the resultset . But I can see the output columns for a sql server stored procedure.

I really do not know what went wrong. I followed the steps from bol and still having a problem. Am I missing something.
I do have a valid email account
I do have a valid domain account
I tested outlook using the email account and it worked. so why sql server does not recognise MAPI.
My next question, How to configure MAPI in Sql server if what I did was wrong.

Hello All,
Soon I shall have to migrate 2 medium sized databases from SQL server 7 to 2005.
Any words of wisdom, “how to�, “do and don’t� would be greatly appreciated.
Here are the details:
SQL 7.0 SP4, on Win2000
SQL 2005SP1,on Win2003
Sql 2005 needs to be installed on a new server (Win 2003), which will also be used as a web server (IIS6). I was thinking to go with a clean install for sql 2005 first, and after that to migrate the databases.
Thank you in advance,
Emily
