Migrating DB from SQL Server (Windows) to Oracle (Unix)

I wish to migrate a SQL Server 2000 database on a Windows environment to an Oracle database on a Unix environment.
Are there any issues with using the Oracle Migration Workbench to migrate a SQL Server database to Oracle between different operating systems?
Thanks in advance.

Hi!
After trying to migrate only a copule of schemas from sqlserver, my solution appeared by itself. It seems that something goes wrong if you migrate only selected users, so I build up a test instance in windows, made the workbench repository on it, and ran a full migration from all the users to this test environment.
After this it was nice, cause I made an exp from the squema I wanted and imported it on production environment.
PD: Migration logs only raised java related problems. I got quite crazy realizing what jdbc version I had, but it wasn't the problem.
By the way, if you try to run sqlloader scripts, be careful with language issues, cause I had to reverse data loading because incorrect typos or so.
Thanks a lot for your help.

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.

How to only migrate data from SQL Server 2008 to Oracle 11?

According to our requirement, We need to only migrate data from a SQL Server database to an existed
Oracle database user.
1) I tried to do it with SQL Developer 3.0.04 Migration Wizard, But find an issue.
My SQL Server database name is SCDS41P2, and my Oracle database user name is CDS41P2;
When I used SQL Developer to do offline move data by Migration Wizard, I found all oracle user
name in movedata files which gotten by run Migration Wizard
is dbo_SCDS41P2. If the Oracle user name is not the same as my existed Oracle user name,
the data can't be moved to my existed Oracle user when I run oracle_ctl.bat in command line window.
So I had to modify the Oracle user name in all movedata files, but it's difficult to modify them because there are many tables in
databases. So could you please tell me how to get the movedata files which the oracle user name in them is my
expected Oracle user name?
2) I also tried to use the 'copy to Oracle' function to copy the SQL Server database tables data
to the existed Oracle database user. When clicked 'copy to Oracle', I selected 'Include Data' and 'Replace' option
But I found some tables can't be copied, the error info is as below:
Table SPSSCMOR_CONTROLTABLE Failed. Message: ORA-00955: name is already used by an existing object
Could you please tell me how to deal with this kind of error?
Thanks!

Hi,
Thanks for you replying. But the 'copy to oracle' function still can't be work well. I will give some info about the table. I also search 'SPSSCMOR_CONTROLTABLE' in the target schema, and only find one object. So why say 'name is already used by an existing object'? Could you please give me some advice? Thanks!

Issue with migration DB from SQL Server 2005 to Oracle 11.2 using SQL Developer Migration workbench

Hi,
We face an issue while migrating an SQL Server 2005 DB to Oracle 11.2. It fails during the process. I hope someone on the forum has seen this before and can give us some advice.
I use the latest version of SQL Developer with JRE included (3.2.20.09). The JDBC driver to connect to SQL Server 2005 is 1.2.0
Here are the steps we take in the Migration Workbench wizard:
I made an online extract of the SQL Server database.
Using the workbench in SQL Developer I created a migration repository in schema PDM_MIGRATION.
Next I start the migration, it captures the tables fine, but immediately after the start of the conversion I get a failed message without further explanations.
This is the content of the error xml:

Does anybody know what this error means and what steps we should take to continue the migration?
I see the PDM_MIGRATION.MIGR_FILTER is a type.
Many thanks in advance,

Hi Wolfgang,
Thanks for your reply.
This is how the type MIGR_FILTER looks like:
create or replace
TYPE MIGR_FILTER IS OBJECT (
FILTER_TYPE INTEGER, -- Filter Types are 0-> ALL, 1->NAMELIST, 2->WHERE CLAUSE, 3->OBJECTID LIST
OBJTYPE VARCHAR2(40),
OBJECTIDS OBJECTIDLIST,
NAMES NAMELIST,
WHERECLAUSE VARCHAR2(1000));
I think the repository user has the correct privileges. This is the overview of privileges it has:
SQL> select * from dba_sys_privs where GRANTEE in ('PDM_MIGRATION') order by GRANTEE;
GRANTEE PRIVILEGE ADM
PDM_MIGRATION ALTER SESSION NO

Migration from SQL Server 7 to oracle 8.1.7 on windows 2000 professional

Hello All,
I am currently working on Database migration from sql server 7 to oracle 8.1.7.
My setup is as follows:
1. Both the databases (sql server and oracle are on the same machine )
2. My sql server database contains 200 tables and 190 stored procedures, which need to be migrated to oracle.
When i am trying to capture the Source database details, its capturing evry thing but when its mapping at the end ...it says "MAPPING ROLE PUBLIC" and its not proceeding furthur..What do u want me to do ? i waited for approx 1 hr , still its not proceeding....How to resolve this bug ?
Also please suggest me the best methodology for Migrating the stored procedures. allmost all my stored procedures have TEMP Tables implemented in it. Please help me in this...
Also please let me know the Timeframe estimate for this total thing to be done..
Waiting for your reply,

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.

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...
cheers,

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.

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 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!

How can I migrate data from SQL Server 6,5 to Oracle 8?

We have a web site based on Microsoft SQL Server 6.5.Now we plan
to migrate the database to Oracle 8.
We have redesigned the tables structure and created tables under
Oracle 8, so we only need to migrate data from SQL Server.
We've exported data from SQL Server to text files.
How can we import data from files and restore to Oracle tables.
Is there a solution which let us to import data for particular
table columns,not all columns?
We'll be appreciated if somene can give suggestions.

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.
Regards
John

Faster way to migrate data from SQL Server to Oracle 10g

We have to migrate data from SQL Server to Oracle 10 g.
One particular table on SQL Server has records around 1.25 millions.
We tried moving data using DTS package, but looks it will take hours with current speed of 300 records/minute.
This table has TEXT column, which has XML strings stored. I am not sure, if this is the reason for slow migration.
Would you please suggest better options to migrate it faster?
Thanks in advance !!!

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.
