Oracle Migration Work Bench

I am trying to capture Access databases into Oracle using Orace Migration Work Bench.I have created XML files for different access databases. The first time when I capture from the source database it captures everything fine. But when I capture the second database, I am loosing all information about the previously captured database
from the migration workbench repository. Any comments ?

For a faster response, post this question in the Migration forum:

Problems with Oracle Migration Work Bench (OMWB)

Hi
I am asking all "migration experts" here to give me a hand.
I'm trying to convert an Access DB with loads of tables to Oracle 10g (Expresss Edition, actually) with OMWB version 10.1.0.4.0 (newest available version) and have some serious problems:
1) The migration creates the complete Oracle data model and database, but does NOT migrate the data to the new DB. This is a pain somewhere, as I have about 80 tables, and the only way which would be working in most cases, but far from all, is to export the data to .csv files and load it on the other side with the "load text data" function of the XE DB.
The first "bad sign" is that the Access application which comes with the work bench and which is supposed to export the data model AND the data (2 separate functions), does the export of the model OK, but the data export only lasts a second, and does not append anything to the xml file created by the data model export
The message I invariably get at the point where the data should be migrated is "Unable to migrate data from source <Access DB table name> to destination table <Oracle table name>;[Microsoft][ODBC Microsoft Access Driver] File "unknown" not found ! Very helpful... What is that ?
2) The "Modify the Access application" phase that comes after the migration only worked once, and now comes up also with an error: java.sql..SQLException: [Microsoft][ODBC Driver Manager] The data source name was not found, and no standard driver was indicated
So, with these 2 things, but especially point 1), most of the use of the tool is gone.
Can someone tell me what I do wrong, or where the problems are ?
Thanks
BAlex

Please contact [email protected] with the following information.
1. Workbench version
2. ODBC driver information
3. Problems encountered
If possible, could you attach the error.log file produced by the Migration Workbench (located within %ORACLE_HOME%/Omwb/Log).
Thanks in advance.

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.

OMWB Oracle Migration Work Bench for MS Access hints

Hey folks,
This is a great tool, however, there are a couple of 'gotchas' you might encounter:
1. When loading data, you may encounter this error:[Microsoft][ODBC Microsoft Access Driver] '(unknown)'. On a windows box, just update the ODBC DSN for omwb_msaccess to point to the file you are importing.
2. Imported rows are not consistent with the actual number of rows imported. i.e. you only get five, but were expecting 100. Check the Access table for garbage data, i.e. values that appear to be garbled or block characters. Delete these rows and rerun the migration tool.
Feel free add other hints to this thread.
Thanks Oracle!

In response to my own question:
The Exporter is part of the installed OMWB. Found it. Ran it. Created a new XML file for the database I'm migrating.

Migrate from Access 97 to Oracle using Migration Work Bench to mi

When I try to use Migration work bench to migrate an Access 97 database to Oracle using OWB I get "failed to truncate Source Model ORA-00942 tables or view does not exist" error message and I could not go further.
This happens during clearing the Source Model. Doe any one know what is this error means or any one had this problem before.
Thanks
Myl

Hi Njha,
Did you create the Source Model using OMWB and then delete the tables in the OMWB repository manually ? Or is there a chance that the tables in your repository could have been corrupted in some way ? The OMWB is simply trying to truncate the tables it filled when a previous attempt was made to capture the source model before it re-populates the tables with data from your subsequent attempt at a capture. If the tables it is trying to truncate have been deleted or are corrupt, this error will be displayed.
A workaround to your problem would be to drop the schema you are using for the OMWB repository and create a new one.
I hope this helps,
Tom.

Migration Work Bench Offline Approach

Hi,
Iam using migration workbench offline approach from sql server to oracle.
I connected to sql server and get the dat files and control files for sql loader.
The control files are generated from the work bench tool where as by default its giving DECODE function for all non numeric data type fields for ex:
EMPNO "DECODE(:EMPNO, CHR(00), ' ', :EMPNO)"
Can i do modification in the tool so that the control file generated with some more functions appended.
I want to convert all non numeric fields to uppercase before inserting to oracle db i.e. iam expecting my control file something like this -
EMPNO "DECODE(:EMPNO, CHR(00), ' ', upper(:EMPNO))"
Please let me know how can i achieve this instead of editing each control file and modifying the same manually.
Regards,
BAIG.

Baig,
I'm afraid, i think this is not possible with the present version of the tool. If there were some intermediate steps between creation of sql loader scripts and generastion of the sql loader scripts, what you asked mite have been possible.
Thank you.

Migration Work Bench Plug-ins

I got downloaded Oracle Migration Workbench for evaluation. I have installed it.
It requires plug-ins which support specific other than oracle databases.
When I consult the documentation, I have found the following information about
downloading plug-ins at the link given. I haven't found any plug-ins there. I have searched
for those in the site. where can I get plug-in's?
Each plug-in available to you is database specific and extends the Migration Workbench to support the migration of a specific database to Oracle. After installing the Migration Workbench you must then install the plug-in for the database you want to migrate. By default, you download the Migration Workbench without any plug-ins. You can download the appropriate plug-ins from the Oracle Technology Network Web site at:
http://otn.oracle.com/tech/migration/workbench/
Thanks

Hi,
Click on the link you mention and then click on the software link on the left of the page (in the naviagation area). If you follow the next few pages to get through the license agreement etc., you will be presented with the full list of software for the Oracle Migration Workbench. You will find all the available plug-ins here.

Blair.

Can Migration Workbench be used to migrate from Informix to
Oracle?

Peddu,
Informix support is planned, but will not be available in the
near future.
Less user-friendly script based kits for informix and other
databases can be downloaded from the OTN Migration Technology

Hope that helps,

Issues using Oracle SQL server Developer migration work bench

Hi all,
We are trying to migrate the application databases from SQL server 2000 to Oracle 10g using Oracle SQL Developer 1.2.1.32.13:
Following is the list of issues that we faced while trying out this migration on dev environment.
1. The data migration was successful for only around 90 tables out of the total 166 tables present. No error message was logged for the rest of the tables but still it was completed.
2. Some of the tables which had got the data inserted did not have the full data. Only some of the rows were inserted for these tables. Error message was logged only for few of the rows and not all.
3. Few error messages were logged which said problems about “Inserting ' ' into column <tablename>.<columnname>”. There was no such constraint in the target database that the particular column can not be null or can not have only a space. Please check the logs for the same error messages.
4. The status box at the end of migration had shown only 3 errors.
5. The total data for migration was around 500MB. The time taken for migration was around 75 minutes. Are there any optimization techniques that will improve the performance?
Please note that there were no Foreign Key references for the source schema or target schema.
Any pointers/info/resolutions related to above mentioned issues will be much useful for us.
Thanks,

Hi Adam,
There are 2 sets of scripts created for you.
1) For SQL Servers BCP to dump out the data to dat files
2) For Oracles SQL*Loader to load the dat files
You run the SQL Server BCP scripts on the machine with SQL Server.
The dat files will be dumped out on that server.
You can then move the dat files to your Oracle server.
Then run the Oracle SQL*Loader scripts to load the dat files into Oracle.
Give it a go and follow the doc and viewlets.
Your Questions:
So the datadump from the source location would be saved on my local disk?it will be saved on the same machine you run the bcp scripts from. Usually the same machine SQL Server is on, because you require SQL Server BCP tool.
So once it is migrated to the destination database will that dump be created automatically? Or do I need to modify the script to take care of this?I dont know what you mean by this, hopefully above clears things up.
The only modifications you need to make to the scripts are adding in the databasename username password servername. These are outlined in the scripts themselves. I would want to do something fancy like dump the dat files to a different directory, then you can modify the scripts, but you should understand what they do first.
Most people would have 500MB of space on their discs , so I can see the problem creating these dat files . The same goes for your 30 GB database.
I hope this helps, but as always you wont get a good idea of how it works until you give it a go.

Dermot.

Hi K,
Whats the default character set of you MySQL and Oracle Databases.
What version of JDBC driver are you using?
Is there any unicode characters used in your data?
Have you tried offline data move?
Thanks

Oracle Work Bench - MS SQL to Oracle

Hi,
I am using oracle work bench for migrating MS SQL database to Oracle 8i. When i am trying to migrate the Stored procedures with cursors, i am get expections. I am able to migrate tables and SPs (which don't have any cursors in it). I will cite an example for better understanding. Assuming the following is SP in MS SQL
create or replace procedure test1
@id varchar(20)
as
declare @cur1 cursor
if @id = '1' then
begin
set @cur1 = cursor scroll KeySet for
select test1 from table_test
end
else
begin
set @cur1 = cursor scroll keyset for
select test3 from table_test2
end
open @cur1
close @cur1
deallocate @cur1
/* END OF PROCEDURE */
When i try to parse it using Oracle Workbench, i am getting the following exception in log.
"Error occured at line 4: OracleWorkBench.sa.test1; oracle.mtg.sqlserver7.parser.ParseException: Parse error at line 4. Encountered: Declare"
Any help is greatly appreciated.

Sadigue,
The Workbench uses an underlying repository, so all the choices you make are saved. However the primary usage of the tool, is one off migration, not continous migration. If you want to rerun multiple times, you should probably generate the offline schema and data migration scripts.
