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.

Migrate from Ingres DB to Oracle

Hi Friends,
I have to migrate from Ingres DB to Oracle and the application developed by Oracle Forms.How can we do this any process of docs.
From my research,I came to know about Transparent gateways,But Oracle will support for this or not I'm not sure.Any such experience shared
will be really useful.
Regards.

We have two more customers that currently are in the process of upgrading from MS SQL but as far as I know no one has actually performed an upgrade this far.
If you want to upgrade to OIM 9.1 you will have to wait until the upgrade scripts are available (estimated arrival H2 2008 according to the latest info I have).
If you would like to discuss this further send me an email on firstname.lastname@my_company.com (you can get the "variables" from my forum profile)
Best regards

Migrating from SQL Server to Oracle 8i

Hi all :),
I am trying to migrate from SQL Server to Oracle 9i.
I am using the Migration Workbench.
Everything goes fine during Capturing phase, but while
creating Oracle model the Workbench just hangs at
"Mapping Tablespaces" for over three hours.
(not exactly hangs in the sense that it responds to mouse
events and I can abort the ongoing activity ...)
What should I do ? Should I let it go on and see what
happens.
I follow each and every step as mentioned in the
documentation ... but obviously I am doing something
wrong. Any pointers ???
However ... if I try to migrate to Personal Oracle 8 ...
the migration goes fine from start to end ... just that
the SQL Server triggers aren't successfully migrated.

You may want to start by downloading the Oracle Migration Workbench. That generally does a reasonable job in moving the tables, stored procedures, etc. from SQL Server to Oracle. If your VB code is database agnostic, it should continue to work without any more intervention. Realistically, however, you'll rpobably have to at least tweak a few things that don't work the same way in the old ODBC/ OLE DB provider and the new one.
The hard part of migrations like this is that you may need to revisit some of your architectural decisions if you want Oracle to perform well. There are plenty of things that one does in SQL Server (i.e. frequent commits) to improve performance that have the opposite affect in Oracle. Identifying and fixing these sorts of things tends to be the largest part of a migration like this. Unfortunately, I don't know of a resource that talks addresses all the possible gotchas here.

This needs the user to have access on all_objects view and it will limit the result upto the numbers of objects returned by the all_objects view.

Migrate from sas spds to oracle 11gr2

Is it possible to migrate from Redhat Linux to Oracle Linux on servers in a Data Center that don't have an internet connection? If so, what is the process?
In my case, tunnel.
Have ssh. Can travel.
Can you ssh into the server? Even via multiple hops? Then you can hook that server up to your Internet connection.
Simple example. Your desktop have Internet connectivity via web proxy 10.1.2.3 on port 8080. Your desktop can reach the server via ssh.
From your desktop, ssh into the server and reverse tunnel Internet connectivity
ssh -R 7777:10.1.2.3:8080 root@server
This creates a tunnel on port 7777 on server - and tunnel traffic on that port to your desktop. Arriving at your desktop, that tunneled traffic is send to the web proxy server 10.1.2.3 on port 8080.
On server, set the proxy variable so that yum, wget and other Internet usage/dependent commands know how to reach the Internet. And the proxy on the sever is the tunnel on port 7777. Thus:
export http_proxy=http://127.0.0.1:7777
export https_proxy=https://127.0.0.1:7777
Use wget google.com to test tunneled access to the Internet. And Bob is not only your uncle, but gives you slack.

Migration from SQL7.0 To Oracle & Uni-code Characters

Hi..
I faced one problem in migration from SQL7.0 to Oracle using
Workbench, which is that all Arabic characters is comming
question marks after the migration.
So does Oracle Workbench supports two_byte code for internationl
languages..

Hi Khalil,
Can you please e-mail [email protected] with answers to the
following questions. We will try and investigate this.
What is the structure of the SQL Server table?
What is the structure of the Oracle table?
Also, what character set did you create the Oracle database with?
What codepage was the SQL Server database?
Are the characters appearing as question marks in an application?
Regards

Problem with foreign and primary keys migration from SQL Server to Oracle

Hi folks, i'm using SQL Developer to migrate from a SQL Server database to Oracle and i'm stuck with a couple issues:
The worst of them so far is the fact that i can't migrate any of the PKs and FKs. After successfully capturing the SQL Server DB model and converting it to Oracle, when the tool generates the scripts, all ALTER TABLE queries that add the PKs and FKs have their target columns duplicated.
for example: when i'm trying to migrate a simple table that contains an Id (PK) and Name columns, the tool generates the following scripts:
PROMPT Creating Table TestTable...
CREATE TABLE TestTable (
Id NUMBER(10,0) NOT NULL,
Name VARCHAR2 NOT NULL
PROMPT Creating Primary Key Constraint PK_TestTable on table TestTable ...
ALTER TABLE TestTable
ADD CONSTRAINT PK_TestTable PRIMARY KEY
Id,
Id
ENABLE
As for the FKs, the tool duplicates the columns as well:
ALTER TABLE SomeTable
ADD CONSTRAINT FK_SomeTable_SomeTable2 FOREIGN KEY
SomeTable2Id,
SomeTable2Id
REFERENCES SomeTable2
Id,
Id
ENABLE
Does anyone have a clue on how to solve these issues? I'd be greatly thankful for any answers!

Hi Fernando,
I was unable to replicate this issue. My primary / foreign keys where defined using unique columns.
PROMPT Creating Primary Key Constraint PK_Suppliers on table Suppliers ...
ALTER TABLE Suppliers
ADD CONSTRAINT PK_Suppliers PRIMARY KEY
SupplierID
ENABLE
I tried a few things like
capturing twice and renaming both models the same
renaming the converted models
but with no luck.
I think this issue is occuring either at the capture or convert phase.
1) Are you performing the capture online or offline?
2) Can you provide a the entire DDL for one of these tables and its indexes to see if I can replicate?
3) Did the capture or convert fail or have to be redone at any stage ?
I all else fails I would attempt a capture and convert again using a brand new repository (create a new schema in Oracle and associate the migration repository with it).

Very difficult migration from MS Access to Oracle with SQL Developer

Dear Developers
I have tried to used for one Project Oracle Sql Developer Migration from Access to Oracle (Application Express). Was about an evaluation if Oracle Express (with Application Express) or Mysql (with PHP) as target database.
I am working with Oracle for 14 years and i earn my money in projects related with Oracle. Of course i am sentimental and i push every time when an opportunity comes to have as an option Oracle.
This time beside my sentimental approach the decision was different.
I will tell you why and i hope that someone there will listen and make something for a better Product.
I was trying yesterday the whole day to migrate an Microsoft Access database. A nightmare....
1. Microsoft Access Exporter 2000 was too slow. For a 25 MB Access database, running time was 15 Minutes. And 15 minutes to obtain an undocumented error. I followed your instruction and eliminate all references etc... as you described in HELP. a lot of time necessary to read and do..... After that i obtained an Error #..16. Sorry that i don't provide you with an exact number error. i don't have it right know and personally i am not interested anymore. For this error i don't find nothing in forums about it.... Search again and again..... Every time after waiting 15 Minutes in which you don't know exactly what application does or if really does something. I decided to delete sequentially macros, modules, forms, querys from Access database and see where Exporter stops... Time and time lost for trying and searching.... Finally i obtained my XML file only by keeping my Access tables. The file was produced even if i obtained at the end Error #5:..... Because was an error i am not really sure if the file was completly consistent with my database.
2. I followed the next steps and with some errors (enabling, disabling constraints, objects couldn't be created because of different reasons) i had my Model and Oracle Schema. I have tried to export the data from Access and import it in Oracle. data exported was in UTF8 and SQL Loader Control file doesn't have
LOAD DATA
character set utf8
So i tried to add the string "character set utf8" in my dozens of CTL files - with a freeware of course.....
Maybe you can say that if i knew that from the beginning i would have set my character set in SQL Developer. I don't know and i will not ever try with this product!
So finally after hours of working and trying and playing with my nerves, reading a lot of forums and documentation, i had an Oracle schema, maybe incomplete because of different errors at so much migration stages.
And now i have tried for the first time in my life MySQL Migration Toolkit. I read that for migration to MYSQL this tool is what i needed.
I recommend you to try the product and see something about the quality required for a piece of software. Is not enough if your product runs OK with Nortwind DEMO Access database. It should run OK with all ACCESS databases.
With the tool i have done the job in 5 MINUTES. Simple, efficiently and without errors. At the end i had the SQL Scripts and the DATA imported in the database.
Difficult to say something now. I am sentimental but i asked mysef if you can do something to improve the quality of the product.
What arguments can we provide for a client in Migration from Access to Oracle ???? Can you honestly answer at that?
Please try this MYSQL Migration Toolkit.....Maybe this give you some ideas about simple tasks and about what we really need...
Best regards
Adrian

Dear Barry and Kgronau
Thank you very much for your response. My Post was after a long day of trying to import an MDB file.
Maybe you can understand why i was so angry...
Yes i understand that your tool try to do more than other even if actually you don't really convert too much.
From Modules to make some procedures where the whole code is commented! .....
For other MDB which i tried to import in APEX the forms where really not usable. Queries are full of errors requires most of the time manual corrections.
I am sorry that i can not provide you with this MDB which cause these problems.
Data and software doesn't belong to me and the company which own it can not provide to you.
What i hope from your product is, even when errors come, to show a better error explanation. At what object in Access error ocures ? This is very important because i can correct my MDB or just delete the module,form,query in cause if SQL Developer doesn't like it....
Just showing an error Error #.... doesn't help me too much. And if an error occurs i don't know if program continues to work or is dead. No information about this. Maybe you can show that your application is alive and does something (working status etc...) ! Anyway we wait long minutes in front of dead screen....
Again, thank you very much for your attention
Adrian

Migration from SQL server to Oracle

Hi,
Has anybody done migration from the SQL server to Oracle? If so, what manual method do you recommend? I'm a new college grad and I would like to get your expertise, if you have done this in the past.
Thanks in advance!
Sho

It is some time back, so I do not remember the specifics. Oracle gives Oracle Migration Workbench for free. You can use it to convert all SQL tables and procedures etc to oracle. It is not that difficult. If there are no stored procedures etc, you can just extract the DDL and create the tables with minor changes to the script. You might need bcp-sqlloader/trasparent gateway etc copy the data.

Migration from SQL Server to Oracle 8i

Hi,
what are the general issues to be considered when migrating a database from SQL server to Oracle 8i.
Is it documented on the web/ or any publication
Samit

What we did was to create the schema using migration work bench and then transfer the data using data junction
The main issues that you have to handle are
1) Data type issue, here problem comes converting chars to varchars as chars are padded and may not work in indexes, so you have to trim the afterwards, and if you have any image type data types in Sqlserver, you can use either lobs or long raw, it again depends upon your application, if you uses lobs you may have to recode your application
2) Sql statements, Oracle cannot understand Sqlserver sql statements, so you have to convert them all. Sqlserver allows two outerjoins to a table, Oracle does not, so you have to modify your functionality
3) Connections to the database. if you are using ODBC then use Oracle ODBC drivers and the latest ones, otherwise you may encounter memory leaks.
These are from the top of my head, if you have any specific problem I may be able to help.
Good luck
