DB Migration from MYSQL to ORACLE Using Offline Capture

Hi
Am doing a database migration from MySQL to Oracle using SQL Developer (version 2.1.1.64). So far, I've successfully captured the MySQL database and converted it to the Oracle Model. However, when generating offline scripts to create the converted model schema into Oracle DDL scripts it managed to generate SQL to create: 1) User 2) Sequences 3) Tables 4) Triggers and 5) constraints.
It has created the SQL to add the primary key constraints and index constraints. Although it did the foreign key constraints in the SQL, the foreign key constraints seems to have missed the cascading options for the foreign key constraint. I.e. theres no reference of whether the foreign key constraint will restrict on delete or cascade etc.
We have a foreign keys in the MySql database that have different cascading options and these have not being ported over into the migration SQL. Therefore, all the foreign keys generated in the SQL by default are cascade to restrict on delete.
Does 'Generate Oracle DDL' not take into account a foreign key's on delete cascading option?
Any help or information would be greatly appreciated.
Thanks

Hello,
that reminded me for the following thread:
Migration Microsoft SQL Sever 2005 to Oracle 11g cascade on delete problem
That is a similar issue, isn't it?
I opened a bug for that, and it will be fixed in SQL Developer 3.1 (not in any 3.0 Early Adopter version). If you hit the same issue, there is no other way then using the workaround as used in the mentioned thread.

Out of memory error in migrating from mysql to oracle

Hi,
I'm trying migrate from mysql to oracle9i. The hardware and software requirements are matching or even much higher than mentioned in the documentation. I have installed OMWB is properly(hope so). When I try to migrate the desired database from mysql to oracle, the repository, the Oracle model are created successfully. But while migrating data, say for around 35000 rows insertion everything works pretty fine. But after sometime, the migration stops and no error or anything appears in the screen.And in the Errorlog I get "OutOfMemoryError".
I tried to migrate single table also. But I still get this problem after sometime. The tables may contain from 10 - 130000 rows...
I even tried to change the %JRE..% memory value to 64M or 128M in the omwb.bat file and the O/s is Microsoft Windows XP, RAM 256MB.
Any help is much appreciated.
Thanks in advance.

Hi Viji,
did the message in the error.log provide any extra information? For example, was the OutOfMemory error prefixed with a string
like "cannot create new native thread" ? My suggestion to workaround the problem would have been to increase the JVM heap size to 128
but this appears to have been unsuccessful for you. Can you send a mail to the Migration Workbench support services
([email protected]) explaining the problem, and attach the full error.log file please ? (please also copy me on the mail).
In the meantime, you can workaround this by migrating the schema only (there is a switch on step 3 of the migration wizard asking:
"Do you want to migrate the table data to Oracle?" - just select the "No" option). When the schema has migrated, you can then use the
offline data loading facility to migrate the data. This uses data extraction scripts and SDQL*Loader to migrate the data to the target
Oracle database.You can learn more about the offline data loading facility from the plugins referenceguide (from the Help menu in
the Migration Workbench).
I hope this helps,
Tom.

How to handle DATE type problems in migrating from mysql to oracle.?

Hi,
I'm migrating only the data from mysql to oracle with the help of sql loader.But with this type i cannot able to insert the date values from mysql to oracle.In mysql i have defined date as "DATETIME" type and in oracle it is in TimeStamp.Whenever i'm inserting the values thru CTL file ,i'm getting an error invalid date format entered.How to solve this problem?
Thanks in Advance

you need to supply a mask to the timestamp entry. see http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14215/ldr_field_list.htm#i1006714 for details on datatypes within the ctl file

Migrating from MySql to Oracle

Hi,
I have installed latest version of SQL Developer with new Extensions (added mysql-connector-java-3.1.14-bin.jar under third-party database extension tab) , also installed latest updates from Help Menu. I have created a database in Mysql and now migrating it to Oracle, while I click on Capture MySQL / Quick MySql migrate... i get error "Error ocurred during capture: ORA-01400: cannot insert NULL into ("ASHISH"."MD_PROJECTS"."ID") ".
Thanks,
Ashish Sohane.

I am having the same problem. I have deleted and recreated the repository many times. I'm getting:
"SQL Error on Script Execution. Try deleting repository before Creating Repository."
then
"The Repository installtaion has failed. Please check the user you are registering and make sure that objects of the same name do not already exist"
I have closed the connection and reopened, closed SQL Developer and reopened. When I expand Tables, there are NO md_ tables. So it seems the repository deletion is working. But when I try to recreate it, oracle somehow thinks the repository I deleted is still there.... even tho it doesn't show it in the ui.
Although this thread began w/ someone converting from MySQL i think that is probably irrelevant. We are getting the same errors with the oracle repository. I am converting from MSAccess2003 using SqlDeveloper 1.2.1. I have successfully created the XML and SQL exports from MSAccess using SqlDeveloper\Migration\MicrosoftAccess Exporter\2003

"Default " problem while migrating from mysql to oracle.

I'm migrating from mysql3.23 to oracle9i via the OMWB tool.While migrating i'm getting an error message "Failed to create default for the table <table>:ora00907 missing right parenthesis".This error is due to the difference in the syntax used for the keyword "default" in mysql and oracle.In mysql we have to give after the Not Null option whereas in oracle we have to give before Not Null.
The problem is i'm migrating via the OWMB tool.Is is possible to handle this error with the help of tool itself.
Thanks
Jai.M

Jai, I'm having Frank have a look at this for you to see if we can replicate it ans help solve this issue for you. are there any issues logged on the mysql site regarding saving blobs as file?
thanks

Migrating from MySQL to Oracle 11gR2 containing accented characters

Hello Gurus,
I am going to migrate a MySQL database that contains accented characters. The collation of the tables holding these data is utf8_unicode_ci.
I used SQLDeveloper to generate data migration scripts. After a test migration run, the web pages displays "?" instead of the accented character.
I am currently tracing where the problem is.
From what I have read, mysqldump uses utf8 as the default character set, so I assume the accented characters in <tablename>.txt files are in tact.
Could the problem be on sqlldr? Has anyone come across this problem?
I really would appreciate any help.
Thanks

Hi Vladimir,
I send you a message from the Migration Workbench team that solved my problem. I hope this will resolve yours too.
Bye,
Pierfrancesco
Hi Pierfrancesco
MySQL 3.22, 3.23 Requirements
In order to migrate from MySQL to Oracle, you must install the MM MySQL JDBC
driver release 1.2a on the same system as the Migration Workbench. You can
obtain this by downloading the MM MySQL JDBC driver from the WorldServer Web
site at:
http://www.worldserver.com/mm.mysql
Copy and unzip the mm.mysql.jdbc-1.2a.zip file to your
%ORACLE_HOME%\Omwb\drivers directory. This automatically creates a new
directory called
mm.mysql.jdbc-1.2a within the drivers directory.
Can you please verify that you have this driver extracted to the above
specified directory. Another check you can do is see whether all the files in
the zip
have extracted.
Please refer to the Release notes which you have access to by selection the Help
drop down menu in the Workbench.
I hope this helps
Best regards

Problems while migrating from mySql DB to oracle DB

Hi All,
I'm using sql developer tool to migrate from MySql DB to oracle DB. I followed the below steps.
1) I've created oracle and mysql connections successfully.
2) I've captured Mysql data and I'm able to see the captured model in ' Captured Models ' window. After that right clicked on the captured model and selected ' Set Data Mapping'. Selected ' apply ' button without changing anything. After that I've right clicked on the captured model and selected ' Convert to Oracle Model ' . It has shown the converting process. After some time it has shown conversion completed successfully.
But converted model is not visible in ' Converted Models ' window.
Can anyone kindly assist on how to migrate from MySql Db to Oracle DB?
Thanks,
Saty.

Hi,
We did mysql to oracle migration some time back and played with workbench tool and many other softwares available.
However our experience was not so good with these tools, each tool had its own limitation and was not able to migrate 100% data. Even the speed of migration was too slow which would have violated our production SLAs.
So after spending a month with these tools we finally decided to create our own scripts for data migration. We used tools like TOAD and SQL Yok to create the DDL for the tables and other DB objects.
For the data migration we downloaded the mysql data in flat files and used sql loader to upload the same data in oracle. Even if this was a time consuming activity but this resulted in 100% data migration with no record getting failed and the time taken for this activity was around 6 Hrs in comparison to time of 24-28 Hrs that the workbench tool took.

Whether using Oracle after migrating from MySQL be easy or not?

Though oracle is tough secured one, I don't know exactly the complexity of using Oracle database. Using MySQL 4.1.22 in my website https://www.puntercalls.com/ . Though the site is based on providing share market tips, it deals with a huge amount of stock market data and in much more real time basis hand-to-hand with NSE and BSE info which means a tough security is the utmost demand of the time.
My question is whether using Oracle after migrating from MySQL be easy or not. You can check my site at https://www.puntercalls.com/ for different real time data updation parts.
Kind suggestions are greatly appreciated in advance!

Hi,
As you are really asking about how to setup and use securioty features in an Oracle database it woul db ebetter to raise the question in this forum -

They will have more knowledge about Oracle security features and which it would be best for you to use.

Best practice for loading from mysql into oracle?

Hi!
We're planning migrating our software from mysql to oracle. Therefore we need a migration path for moving the customer's data from mysql to oracle. The installation and the data migration/transfer have to run onto different customer's enviroments. So migration ways like installing the oracle gateway and connect for example via ODBC to mysql are no option because the installation process gets more complicated... Also the installation with preconfigured oracle database has to fit on a 4,6 GB dvd...
I would prefer the following:
- spool mysql table data into flat files
- create oracle external tables on the flat files
- load data with insert into from external tables
Are there other "easy" ways of doing migrations or what do you think about the prefered way above?
Thanks
Markus

Hi!
Didn't anyone have this requirement for migrations? I have tested with the mysql select into file clause. Seems to work for simple data types - we're now testing with blobs...
