Oracle Migration Workbench : import sqlserver database into exiting schema

Dear Oracle users,
I have to migrate several databases from MSSQL 2000 to Oracle 10g.
To perform this task I use the oracle migration workbench, which works great for that purpose.
My only problem is that the Oracle Migration workbench creates alsways a new
tablespace with the same name than the sqlserver-user I use to export the database.
I would like to import the converted database into an already existing schema of my Oracle database.
Does someone know how to do that ?
Best regards,
Daniel

Change the name of the SQL server user to the name of an oracle tablespace name. This should create the tables in the Oracle tblspce you want.

Migrate Informix 7.31 Database into Oracle

Dear all,
I intend to import an Informix Dynamic Server 7.31 Database into Oracle; In this case it's the database of an old system which is not in use anymore, so the purpose is strictly readonly.
No triggers, few procedures and functions.
I'd like to import the data into Oracle 11g, is this possible or do I have to import into 10g and then upgrade to 11g?
The docs say the migration workbench is the tool of choice, is there anyone who can provide me with some experience?
How do I verify the migration was successful and the data was imported exactly the way it was?
Thanks in advance,
Andy

Andy,
Informix can only be migrated using the older Oracle Migration Workbench 10.1.0.4 and as it says on the web site -
http://www.oracle.com/technetwork/database/migration/informix-085032.html
the only supported versions for the workbench are 9i and 10g.
However, this is only for running the workbench itself and creating the repository. If you do an offline migration then you can run the scripts created by the migration utility in any version of Oracle and load the data using any version of SQL*Loader.
It may be that you can create the repository for the 10.10.4 workbench in an 11g database but I've never tried it.
As for testing there is a section in the documentation -
Oracle® Migration Workbench User’s Guide Release 10.1.0.4 for Microsoft Windows 98/2000/NT/XP and Linux x86
Chapter 7 - Testing the Oracle Database
that discusses how you can test the migrated data.
I've only ever run small test migrations and issues can depend on the complexity of the data and particularly stored procedures and embedded SQL.
If you have no triggers, few procedures and functions then it should be fairly straightforward.
It is planned to include Informix migration in a later version of SQL*Developer but there is no date for that yet.

Mike

Limitations of Oracle Migration Workbench in migrating sqlserver 2000

Error when using Oracle Migration WorkBench (Sql Server 2k to Oracle 8i)

I'm trying to migrate a Sql Server 2k database to an Oracle 8i schema using OMWB. After using BCP to collect metadata information on the source database, I tried to capture the source data model and got a "Capture aborted" message on the progress screen (even though then it appears a dialog window reporting "0 errors and 0 warnings", funny!). Down there is the error log OMWB generated. After reading some posts, I changed some columns of the OMWB dictionary that holds the source database name, but still got the same error. If someone can enlighten me on this toppic, I'd greatly appreciated it.
Here's the error log of OMWB:

Problem migrating MS Access to Oracle 8i using Oracle Migration Workbench

Downloaded Migration Workbench. Ran setup but it says that the Migration Workbench must be installed into an Oracle 9 home. I though it would work with Orachle 8 (according to the documentation). We obly have ORacle 8i here.
Does anyone know away around this?

Hi Caroline,
the workbench just needs to be installed into an Oracle 9i home or a new ORacle Home. It will still work against an Oracle 8i database.
There is a dedicated Migration Workbench discussion forum available.

Access 2003 to oracle 9i Migration(Oracle Migration Workbench)

Hi Experts,
I have taken up a project to migrate Access 2003 application to Oracle 9i.The Forms and Reports will continue to run in Access 2003 with Oracle 9i database. I decide to use Oracle Migration workbench for the migration purpose.What I think is the back-end i.e. database and queries will be automatically migrated to Oracle 9i but I'm not sure about the front end application.
Do I need to change front end application to point to database in Oracle 9i or OMW will do that itself.I am also confused with lots of queries that reside in current Access database. I presume these queries will be converted to Oracle procedure without any manual intervention but will the front-end application also be modified automatically to point to those stored procedures.Otherwise an extensive code change will be required which may result in huge cost.
So, could anyone help me in this issue by giving some ideas so I can manage the job efficiently.
Thanks & Regards
S C

The Migration Workbench will modify the Access mdb file as part of the migration if you request it, to create the necessary link tables to oracle, it will use an ODBC DSN to do this. This is explained in our documentation. This should be transparent.
However for complex application, you often have a tuning exercise, to ensure that the jet engine does the "right" thing, and there changes are required, e.g. a two way join, you would want that to happen on the server and not done on the client. This would be same tuning exercise, if the back end was SQL Server.
In the latest release of the Access plugin, we did a better job migrating queries to views, but you need to plug this into your code.
Yes, the exporter should extract the information about the linked table, assuming the link is valid at the time of extraction.

MS SQLServer7 and Oracle Migration Workbench

I want to have Oracle schema name=MS SQLServer7 database name when I migrate MS SQL Server 7 database using
Oracle Migration WorkBench ( v. 1.3.1.0.0 ).
Then I tried to migrate NORTHWIND database from MS SQLServer7 Oracle Migration WorkBench have created user SA
and tablespace NORTHWIND in the destination Oracle database
By default MS SQL Server database names are mapped to the Oracle tablespaces, but there is an option 'Tablespace discoverer' to change destination tablespace.
But I do not see an Oracle Migration WorkBench option to make Oracle schema name=MS SQLServer7 database name.
Only ways I see :
1) to use 'Generate Migration Scripts' option
in menu 'Action' and edit the scripts manually
( I do not like it, unless you cannot suggest script to automate
this task )
2) Rename Oracle user ( user='SA' in my example ) to
'NORTHWIND' after migration , but how to do it ( ALTER USER) ?
Thanks,
Michael.

Mishel,
Another alternative is to alter the MS SQLServer7 database owner to NORTHWIND using
sp_changedbowner (T-SQL)
Changes the owner of the current database.
before migrating the database.

Can Oracle Migration Workbench 2.0.2.0.0 be used to migrate SQL 7.0 to Oracle 8i?

Hi,
Does anyone know that can Oracle Migration Workbench 2.0.2.0.0
be used to migrate SQL 7.0 to Oracle 8i? or the version
2.0.2.0.0 can be only used for Oracle 9i?
I failed to install Oracle Migration Workbench 2.0.2.0.0 onto my
workstation(running Oracle 8.1.7), because it need Oracle 9i.
Thanks

One more question: where can I download the Oracle Migration
Workbench 1.4.1.0.0 in order to migrate non-oracle database to
Oracle 8i?

Oracle Migration Workbench logfile?

After I create my migration project I go to look at the table and it is invalid, clicking on the - under Oracle Tables it says:
The associated Microsoft Access table was not successfully migrated to Oracle. Review the Oracle Migration Workbench logfile for further information.
Where do I find the logfile?

Hi,
Can you confirm that you carried out the migration of the MS Access database schema using Oracle SQL Developer Migration Workbench before creating your migration project? I would recommend reviewing the steps outlined in Chapter 21 - Migrating Applications in the APEX User's Guide.
I hope this helps.

Oracle Migration Workbench DB2 UDB 8.1 Plugins..

I want to migrate db2 udb 8.1 database to oracle 10g ...But iam not able to find the plugins for db2 udb 8.1 in oracle site...... Oracle migration workbench is asking for db2 8.1 plugins can u suggest where i can download ....

From an earlier post on this forum, found by searching for db2:
No plans for DB2 V8 support in the short term. The plugins are hardwired to work against the version they are built against, so it won't work with V7. There are other alternatives out there. One example would be from Ispirer: http://www.ispirer.com/products/ or
from SwisSQL: http://www.swissql.com/oracle-migration.html
[I assume 'so it won't work with V7' in the source post should read 'so the db2 v7 plugin will not work with anything other than db2 v7']

Installing Oracle Migration workbench 1.2.2.2.0

I have Oracle 8.0.5 client and server installed on NT workstation 4 sp 5. I have oracle home pointing to this installation of Oracle. But when I use Oracle universal products installer to install this software I get message:
You should be in admin group of your local NT machine(which I am as I installed Oracle 8), or you do not have enough disk space( which I have almost 700 MB free) or you are pointing to incorrect oracle home. Please advise.
Thanks..
Sumedha

Oracle Migration Workbench 1.2.2.2.0 is based on Oracle 8.1.5
8.0.5 uses a very different oracle installer, please install the Orace Migration Workbench 1.2.2.2.0 in a seperate (new) Oracle Home.
You may need to do some sqlnet configuration so that the Oracle Migration Workbench can connect to the 8.0.5 database.
I hope that helps,

ODBC errors for Oracle Migration Workbench and SQL Server 2000 on Windows

Hi all-
I setup a new ODBC connection for the Oracle 10g Migration Workbench to MS SQL Server 2000 on Windows XP and keep getting the following errors when I try to
either test the new ODBC connection to MS SQL Server 2000 for use with the Oracle Migration Workbench tool. Goal is to fix these errors so that I can migrate our test SQL Server 2000 databases to Oracle 10g.
Current configuration
- Oracle 10.1 Migration Workbench
- Oracle 10g Database (target)
- MS SQL Server 2000 (source database)
-Windows XP
-ODBC 3.85.1117 driver for Windows XP with SQL Server and Oracle
Errors:
I. When I test the ODBC connection:
Microsoft SQL Server ODBC Driver Version 03.85.1117
Running connectivity tests...
Attempting connection
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Specified SQL server not found.
TESTS FAILED!
Now here is what has me totally confused:
I can use the command line ISQL to access the database on the server and IP is all correct and port is available. So I can access the SQL Server database fine it is when I try to setup ODBC that it gives me problems.
Any tips how to get this ODBC working?
Thanks
Ben Prusinski

1. Jing Jin. If you had READ the post you would have seen that installing later versions is NOT an option.
2. Not supported does NOT mean does NOT work, as Balmukund pointed out in the referenced thread. The site that this databases supports is using ASP which is also NOT supported by Microsoft. As it turns out Balmukund's solution actually turns
out to be the correct solution. I installed SS2K and its Service pack 4 on the machine last night. Good answer Balmukund. as we say in the Navy, "BRAVO ZULU!!" which means "WELL DONE!!
3. Tom Li I just posted the question less than 48 hours ago. My last post was less than 24 hours ago. I think I have the right to be given the opportunity to determine whether a reply is the answer or not. I understand you don't like unanswered
posts sitting around for weeks, months or years. (I don't like it either as I have a few that are still unanswered after several years.) But you should not be showing replies as answers before I even get a chance to see them, much less try them out.
You should also not be showing replies as answers which don't address the criteria of the question. I specifically stated that I had to install SS2K. I went on to state, "And before anyone asks I need to install this version because that is what
the customer is using and I need to duplicate their databases." So the correct answer, if in fact SS2K did not work on Windows 7, would have been a virtual machine answer, as suggested on the thread Balmukund referenced. So before you mark a reply
as an answer read the question.

Dear Oracle Migration Workbench Team

I have issues migrating blobs from Informix to Oracle. Our production table containing a blob is more than 100 million rows. During the offline load for a test table with 13,000 records, the load failed with message:
SQL*Loader-309: No SQL string allowed as part of PG_FULL_IMG field specification
Are you aware the offline load doesn't work or the HEXTORAW generates the above message? Is the fix going to available soon?
Also, the can the READSIZE option parameter be increased to 100MB instead of 20MB in future Oracle releases? I cannot load TEXT/CLOB when the size is more than 20MB. Any workaraound?
For online load, can I just do a load for selected tables only?
Thanks.
Norman

Norman,
There is a script to help offline blob move to oracle seaqrch this forum for start.sql.
There is a bug whereby online BLOB and CLOB transfer mixes up rows Bug 4119713 this is fixed in the latest developers release 10.1.0.3 for migrating informix to oracle and will be fixed in the next production release for all plugins.
Also, the can the READSIZE option parameter be increased to 100MB instead of 20MB in future Oracle releases? I cannot load TEXT/CLOB when the size is more than 20MB. Any workaraound?It is unusual to have such large TEXT/CLOB sizes, can the READSIZE parameter be configured by hand in the scripts?
For online load, can I just do a load for selected tables only?After doing a migration and creating the tables without the data, the data can be migrated for individual tables using a right mouse click.
