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!

Migration from of database and app from SQL server 2005 to Oracle 10g

Hello Every body,
Lately, I have been requested to migrate one inhouse developed hub application from SQL server 2005 to Oracle 10g. The objective is to move application and also the database to Oracel 10g.
Here is the current platform:
OS Win 2008 64 bit
JDK 1.4.2
JBoss 3.2.5
EJB 2.1
My question is what kind of issues you guys see in above upgrade. As far I know, Schema and Database migration can be done by Oracle workbench. Oracle 10g supports JDK 1.4. Oracle 10g also supports EJB 2.1.
Anything, I need to take into consideration or any risks or problems. I would like to list down all the risks, and accordingly, I am thinking of start the upgrade.
Thanks in advance.
Regards,
Zeeshan Qureshi

In general the Java/J2EE application needs work in the following categories:
1. Connection Settings: Use Oracle JDBC drivers, create new data sources, connection pools and what not. Disable AUTOCOMMIT for Oracle JDBC Connections.
2. For EJBs, you should regenerate the entity beans because some object names/column names might have changed in oracle.
3. Any custom SQL that is in use in the EJBs will have to be ported to Oracle just as you would do in stored procedures and other applications.
4. For Java front-ends, if you are using callouts to stored procedures and expecting result sets then they will require some changes. You need to modify the stored procedure call signature to include the REF CURSOR variables and process them.
5. Changes to any SQL Server specific database functions manipulating character/date data will be required.
6. CLOB/BLOB/XML apis are different across databases so if you are using those then focus on them as well.
7. Retreiving Auto/generated keys from database also may need changes from what I have seen.
Hope this helps..

Migration from SQL SERVER 2008 to Oracle 10g issues.

Hi ,
I'm trying to migrate from SQL Server 2008 to Oracle 10g and I end up with some issues that I wanted to ask some info about it.
First, I was following a tutorial
http://st-curriculum.oracle.com/obe/db/hol08/sqldev_migration/mssqlserver/migrate_microsoft_sqlserver_otn.htm
and and in the last version of Oracle SQL developer I downloaded, I didn't find the Load Database Capture Script Output option.
My first question is how can I either add this option or is there a new way to load the capture script ?
Then I use the migration wizard and after following everything, I had the migration complete message from the application.
When I tried to open my connectionss, it tells me version 11.2 is required. Does that mean that Oracle SQL developper 3 only
do the migration for oracle 11g? And if I tried the previous versions, it doesn't support SQL server 2008.
What do I do in this case ?
Thanks !

Thank you for your reply.
After using the wizard and made the offline migration script, in the Migration projects window I made a move data to the oracle connection I previously made and after when I tried to reopen the connection, I couldn't.
Well I didn't retry it yet to see if I'll have the same behavior but basically this is what I think I did. When I tried to open the connection I made, it says, Oracle 11.2 is required.
Now, I just generate target from the convert model and it says migration complete but how do I test it and I do I go to oracle and see change ?
Do I had to create a special user in SQL Server to log to it first ? How do I logon to it ?

Migrating From Sql Server 2005 to Oracle (Uniqueidentifier Issue)

If i want to migrate from SQL SERVER 2005 to Oracle, How Oracle will deal with my primary key columns in almost all tables having datatype of UNIQUEIDENTIFIER ???
is there any concept of uniqueidentifier in Oracle same as in SQL SERVER ????
Regards

When you migrate your SP's from SQL Server to Oracle the parser basically does 'as good a job as it can' to migrate them.
Luckily, using SQL Developer you are able to look at the source SP and converted SP in windows next to each other and see what oracle has done to them.
You can also paste your SQL Server code into a window and ask SQL Developer to translate it to oracle for you. Use the 'Translation Scratch Editor' on the migration menu if this is something that interests you. I was told that the parser used by the Translation Scratch Editor is different to the parser used when migrating the whole database.

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 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

Migrating from SQL Server 2000 to Oracle 10g

Hello,
I am a newbie to Oracle 10g and haven't really worked with Oracle since 8i. I have been tasked to migrate all of our databases and tables to Oracle 10g. I need a little help getting started or pointed in the right direction on how to copy all that data from SQL Server to Oracle 10g. I know that Oracle has an Import/Export Utility, but don't know if it can do what I need. Can some one help point me in the direction I need?
Thanks, Marion

Ayub
You need to download both the Oracle Migration Workbench core tool and the SQL Server 2000 plugin (SQLserver2k.jar). You copy the plugin into the plugin directory, after you unzip the Oracle Migration workbench main.
The tool comes with release notes and a user guide, that explains the necessary setup and migration process.

Hi,
I have tested using the following -
SQL*Developer Version 3.0.04 Build MAIN-04.34
and did the following -
Tools - Migration - Translation Scratch Editor
- made sure I was using the 'Microsoft SQL Server T-SQL to PL/SQL ' option in the 'Translateor' tab.
Then in the worksheet put in your entry -
PRINT '@HID=' + CAST(@HID AS VARCHAR(100))
This is then translated to the following -
BEGIN
DBMS_OUTPUT.PUT_LINE('@HID=' || CAST(v_HID AS VARCHAR2(100)));
END;
Is this what you did and the entry you typed into the scratch pad ?
If not, can you give the full code that gave the error -
DBMS_OUTPUT.PUT_LINE('@HierID=' || CAST(v_HierID AS VARCHAR2(100)));
DBMS_OUTPUT.PUT_LINE('@NodeType=' || CAST(v_NodeType AS VARCHAR2(100)));
DBMS_OUTPUT.PUT_LINE('@NodeTypeReqd=' || CAST(v_NodeTypeReqd AS VARCHAR2(100)));

dbf it's not sql server.

SQL Server databases have three types of files:
Primary data files
The primary data file is the starting point of the database and points to the other files in the database. Every database has one primary data file. The recommended file name extension for primary data files is .mdf.
Secondary data files
Secondary data files make up all the data files, other than the primary data file. Some databases may not have any secondary data files, while others have several secondary data files. The recommended file name extension for secondary data files is .ndf.
Log files
Log files hold all the log information that is used to recover the database. There must be at least one log file for each database, although there can be more than one. The recommended file name extension for log files is .ldf.

Are you migrating or taking continual updates?
If migrating it might be worth considering The SQLDeveloper Migration Workbench (which moves more than just data)..

Automating Data Migration from SQL Server 2005

Hi All,
I need to migrate data from SQL Server 2005 to Oracle DB ( Datawarehouse). The data migration involves updating Dimensions and Fact table. I have got painful job of switching topology to point to over 100 different weekly SQL DBs ( in sequence) and pull the data into DW. How can I automate my ODI process to switch from one after the other.
Any Ideas?
KS

ODI Variables are there to help you with this. Please go through this post at [http://blogs.oracle.com/dataintegration/2009/05/using_odi_variables_in_topolog.html] .
This will show you how to use a variable Oracle data server.
On similar lines you should be able to switch to any of your 100 weekly SQL server DBs.
And loop in a sequence to load data from all of them.
Hope that helps

Data length problem migrating from sql server 7 to oracle 8i

I just migrated SQL Server 7 database to Oracle 8i db and everything seemed to have ran ok except that in my newly created oracle database, the field size is doubled. For instance a field with nvarchar(4) in sql server would convert to varchar2(8). Has anyone ran into this problem and also does anyone know how to fix it? Thank you so much.

Hi Roberto,
You cannot use Workbench 1.2.2 to migrate from SQL Server 7 to
Oracle 8.
However, the good news is that we have a new verion of the
workbench that will have a plugin that can migrate from SQL
Server 7.0 to Oracle8.
A beta version will be downloadable from this web-site in approx
one week. Eventhough this version is a beta version, it has
undergone some rigourous testing and is very close to production.
