Migrating from SQL to Oracle 10g -- Oracle Migration Work Bench

All
I've come across this tool from Oracle for Migrating SQL and mySQL databases to Oracle 10g. But the procedure and documentation was not clear. I wanted to try this once and hence I am posting here.
Could you please share your experiences if you have also tried this one already? All your inputs will be of great help in helping me understand this tool and its usage.
Thank you.

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 ?

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.

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.

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!

The hardware can be changed if needed. Can you please suggest the best approach ?
Thanks,

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.

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.

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

Migration from SQL Server 2008 to Oracle 11g

Hi there,
I have a quick question, Anyone who have experienced to migration procedures,function from SQL Server 2008 to 11g R2. Is it possible? I migrated tables and views through Oracle heterogenious servinces but I am not sure about the fucntions and procedures.
Any help would be appreciated.
Warm regards,

Automated conversions are possible. After these conversions the system will pretty much run. However, and it can be a pretty big HOWEVER, performance could well take a hit - which the uninitiated or SQL Server acolytes will seek to blame on Oracle not being very good. This is not actually the case.
You could be in for a major review and rewrite. Besides the syntax differences in the procedural languages, there is a huge - like really huge - difference in transaction control, isolation, and read consistency. Basically, keep in mind that Oracle reads do not block writes, writes do not block reads, and there are no dirty reads. Writes only block other writes. Thus, no coding 'tricks' are needed to get around these blockers. Oracle has global temporary tables that are generally used to help out those converting from SQL Server. In actuality, then are mostly not needed as you can almost always do your work in one SQL statement.
Read the concepts guide from cover to cover, then do it again, then start looking at what you need to do to convert your procedural code.

Migration from SQL Server 7 to Oracle 8i

I am new to Oracle, is there a way to migrate all tables and store procedure form SQL Server 7 to the oracle database
thanks;

I understand that it would not be in the best interests of Oracle, monetarily that is (at least in the visible/tangible sense), to develop such a migration tool, but since the competition hasn't, why shouldn't you? I'm sure Prabha's not the first to inquire of such a thing, and I'm sure I'd have asked a similar question if I wasn't responding to you in this way. We all know Oracle is the better db - That's why we're here talking about it - but not everyone we do business with understands that, so establishing a two way street is the best way, short of requiring it of our clients, to turn them on to Oracle. I don't really think developing such a thing would hurt your business (unless MS can keep you from doing it). If your product is that much better (which we agree is true), you shouldn't be afraid of the competition. As for being afraid of proprietary constraints, I can't blame you, because I don't know how much it constrains you.

My first reaction to your question would be "why would anyone want to migrate FROM Oracle and TO SQLServer ?". Oracle is easily the better database !

Error happened during the migration from sql server 2000 to oracle 8.1.7

/*[SPCONV-ERR(18)]:CREATE TABLE TT_CHANP1 statement passed to ddl file*/
DELETE FROM TT_CHANP1;
error as above.
note:
chanp1 is a temporary table under sql 2000
syntax:
create table #chanp1 (chanpid varchar(50))
we try the codes:
CREATE TEMP TABLE chanp1
Error: PLS-00103: "CREATE"
begin declare end exception
exit for goto if loop mod null pragma raise return select update while
<an identifier><a double-quoted delimited-identifier>
<a bind variable><<close current delete fetch lock insert open
roll back save point set sql execute commit for all
<a single-quoted SQL string>
Line: 63
we try " CREATE GLOBAL TEMPORARY TABLE chanp1" again.
but error .

it seems like you are trying to perform a DDL from within the PL/SQL code, which is not allowed directly.
You could use EXECUTE IMMEDIATE within your pl/sql code to perform a DDL statement.
