Migration from Access to Oracle through SQL developer

Hi,
I want to migrate an mdb file which contains a set of tables to oracle. During this process, i have created schema and all the tables in Oracle using DDL scripts. I would like to transfer only the data to Oracle from access through SQL developer. How can I do that?
Regards,
Meena

Hi Meena,
You mention that you have created the schema and tables in Oracle using DDL scripts. Did you use the Oracle SQL Developer Migration Workbench, creating a Migration Repository, to carry out this process? I see from your other postings that you are experiencing issues using the Exporter tool, which would lead me to believe that you haven't used the Migration Workbench to migrate your database. Obviously you will need to resolve your Exporter issues before you can proceed to the next phase of the migration process. I will aim to assist you with those issues on the seperate thread - ShowSplashScreen("_OracleSplashScreen",3) error The XML file generated by the Exporter tool forms the basis of your MS Access migration.
In order to migrate your data from MS Access to Oracle using the Migrate Data option in Oracle SQL Developer, you will need to have access to the Migration Repository used for the migration of the MS Access database. The information contained in the Converted Model, in the Migration Repository, is used during the data migration process. The data migration requires the following connections:
1. a source database connection i.e. a database connection to the MS Access MDB file
2. a target database connection i.e. a database connection to the migration Oracle schema
3. a Converted Model connection
For further information on the creation of a Migration Repository, and the migration process, please refer to the accompanying documentation available via the online Help within Oracle SQL Developer, and also from OTN - http://download.oracle.com/docs/cd/E10405_01/doc/nav/portal_booklist.htm.
I hope this helps.

OLE object Migration from Access to Oracle through SQL developer

Hello,
I used sql developer 3.1.07(oracle 11g) to perform data migration from MS ACESS.
the MS access data has a column with data type as "OLE object" ---there
saved a lot of pdf files .
Then I performed "copy to oracle" from MS access connection, the OLE data
changed to BLOB from oracle database, and data seems to be copied to
database as binary . However none of the data in the column can be opened. I
download the blob data to a file from sql developer and tried to open
using Adobe 8.1 with no success.
How can I fix this issue? or I should say, how can I migrate MS access OLE data to oracle?
Thanks,
H.M.

thx - will have a look

But when I try to save the content in the BLOB as a file it claims about a missing mime extension and when I ignore this message and save the file anyway as a PDF the content is corrupted.
It shows as :

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

Migrating from Access to Oracle - Captured Model did not convert

I'm trying to convert an Access database 2003 to Oracle using SQL Developer. I've worked through the migration process to the point where I need to convert the Captured Model to a Converted Model. The first time I ran that step, the application told me there were some issues with some indexes and didn't convert my captured model. I decided to delete my captured model and rerun the process from the point where I import the .xml file and recreate the captured model. I then tried again to create my Converted Model and again it didn't generate. The Converting Database dialog box tells me that it's 'converting the database' and it's 'transforming identifiers' but it just hangs and does nothing. What did I do wrong and how to I correct my issue so that I can create my Converted Model?
Thank you.

I was able to get past the Capture Model "hang up" business about three weeks ago. (I'm trying to migrate the Access 2003 Northwind db to APEX 3.2/Oracle 10g.) I found a thread in another forum that noted the problem could be due to a memory issue. This particular post referred to an omwb.bat file in a folder omwb. This may have been referring to an earlier version of SQL Developer -- I could not find the bat file. I'm using SQL Developer Version 2.1.1.64.45. I did, although find a sqldeveloper.bat file in my installation path: C:\Software\sqldeveloper_2.1.1.64.45\sqldeveloper\sqldeveloper\bin. In that file there is one very long java command. And at the very start of that command, I changed
from: java -Xmx640M -Xms128M .................
to: java -Xmx1024M -Xms640M ................
In the java documentation (http://java.sun.com/j2se/1.4.2/docs/tooldocs/windows/java.html) this notes that changing these parameters effect the size of the initial and maximum memory allocation pool.
So that was pretty great -- that it worked. I am at the point now where I've retrieved it all into APEX but it is all invalid and there are so many issues going on all at once that I need to put the project on hold. There is not very much management patience for something like this that goes on and on. Maybe I'll work on it a bit at night now.
Hope the memory thing helps someone.

Migrating from Access to Oracle

Hello......
I am trying to migrate a table from Access to Oracle. It contains approx 850,000 rows, and I tried using SQL Server's DTS Import/Export tool to perform the migration. However, this export/import has been running for almost 48 hours (crazy, huh?!), and I'm only at 350,000 records loaded. This tool is obviously not sufficient for a migration of this size.
Can anyone suggest a better way for me to go about this?
Thanks,
-Christine

Hi,
If you have DDL structures in Oracle, then you can save the access data as .csv file format. you using any opensource tool you can migrate it.
Or you can go for sql loader also.

Migration from Access to Oracle 10g (Problem with migration wizard)

Hi
I have an access database which I want to migrate to Oracle DB.
I have created 2 connections.
1. Access connection with the source database
2. Oracle connection.
I have associated the oracle connection to the repository.
When I go through 'MIGRATION WIZARD' process. I am not able to view the source database file while capturing. Tried it several times.
Need a help in this
Regards,
Arjun
Edited by: 919650 on Mar 9, 2012 2:47 AM

Arjun,
you cannot do an online migration with MS Access as you can do with other foreign datasources. You can only do an offline migration.
The first step that you need to do is to call the Microsoft Access Exporter. Click on Tools - Migration - Microsoft Access Exporter and chose the exporter of the MS Access version that you are using.
The exporter creates an xml file for you. After the exporter has finished you can do the migration, click on Tools - Migration - Migrate, but in Step 4 please select "Offline", and then you can select the xml file that the exporter has created. The following steps in the Migration assistant are then doing the migration for you.
You might also want to read the chapter "Before Migrating From Microsoft Access" in the online help of SQL Developer.

While migrating from access to oracle ??

While loading data from SQL Loader, DATE is taken as dd-mmm-yy (eg: 18-MAR-02) even after specified in "mm/dd/yyyy HH24:mi:ss" in controlfile. How to resolve this problem ???
rgds,
manish

Hi,
Did you follow all the steps in the SQL*Developer documentation about preparing the Access database for migration -
Oracle® SQL Developer User’s Guide Release 3.0 -
2.2.4.3 Before Migrating From Microsoft Access
and -
Oracle® SQL Developer Supplementary Information for Microsoft Access Migrations Release 3.0
2.4 Preparing the Microsoft Access Database for Capture
The error also indicates there may be a problem with your Access installation so could you check that everything is okay with that ? I have found references that indicate a re-install of Office/Access will prevent the error.

Mike

Problems with migrating from access to oracle

OMWB has a few problems with upper and lower case letters, when i try to modify my old access DB OMWB cant find the new table in Oracle:
(3011 The Microsoft Jet database engine could not find the object <name>. Make sure the object exists and that you spell its name and the path name correctly. )
the problem is that it searching for AP_BILD.A990BILDER but the correct name is AP_BILD.a990Bilder
when i recreate the table as AP_BILD.A990BILDER it worked.
but i cant do that for almost 400 tables!
any suggestion how to fix this?
also have a problem when creating the trigger:
OMWB puts the tablename into 2 double quotation marks each side (""name"") and of course it tells me something of a tablenamelength of NULL and it doesnt work
working with release 9.2.0.1.0 of OMWB

update: if i try to link the table from access directly it also cant find the table, but can find other tables (the others are in upper case).
could it be a problem with the odbc driver? does it automatically look for upper case names?
anyone know how to fix this?
thanks in advance

Migrate MySQL db to Oracle with SQL Developer / Migration Workbench

I'm having a problem migrating a MySQL database to an Oracle database. I can make the connection to the MySQL database and query the data, but I can't do the migration.
When I right-click on the MySQL schema, "Capture Schema" is greyed out. Same problem with clicking on an individual table. Also, the menu item "Migration --> Migrate" is greyed out.
Can you help?

Yes, I created a repository. And after your question, I clicked on the repository and was able to get the Migrate Data option for the first time. Thank you!
Before I had been choosing the source database, which wouldn't allow me to choosse the Migrate Data option no matter what I did.
Thanks for pointing out the obvious!

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.

Issue during migrating from Sybase to Oracle using Oracle SQL Developer

I am using SQL Developer v 3.2.20.09 to migrate from Sybase to Oracle Pl/SQL 12c
While migrating the stored procedure the following block did not convert. I got NULL instead of object_id:
Sybase Block:
IF OBJECT_ID(‘dbo.CheckEst’) IS NOT NULL
BEGIN
DROP PROCEDURE dbo.CheckEst
IF OBJECT_ID(‘dbo.CheckEst’) IS NOT NULL
PRINT ‘<<>>’
ELSE
PRINT ‘<<>>’
END
Oracle Block after conversion:
BEGIN
IF NULL/*TODO:OBJECT_ID(‘dbo.CheckEst’)*/ IS NOT NULL THEN
BEGIN
DROP PROCEDURE CheckEst;
IF NULL/*TODO:OBJECT_ID(‘dbo.CheckEst’)*/ IS NOT NULL THEN
DBMS_OUTPUT.PUT_LINE(‘<<>>’);
ELSE
DBMS_OUTPUT.PUT_LINE(‘<<>>’);
END IF;
END;
END IF;
END;
Lines 1 & 4 got converted to NULL. I have many places where such code is written.
Is there any quick way to overcome such an issue? or what needs to be done in such case?

Hi,
You are using an older version of SQL*Developer. Could you download the latest 4.0.2 version available from here -
Oracle SQL Developer
and check if you still have the problem ?

it took one and half day but didn't work at last...
is there any pre tasks that i need to do before migrating to oracle from MySQL?
and also when i export the MySQL data to Oracle using SQL Developer,it is giving data type mismatch errors like (date, boolean etc...).
please give a reply what i need to do and any refferences also very much appreciated.

How do I migrate views from MS SQL 2008 to Oracle 11g through SQL Developer

Is there any way to migrate the views from MS SQL 2008 to Oracle 11g through SQL Developer? Please give me some detail steps. Thanks for your help.

Hi Turloch,
When I use migrate to oracle, I got a problem, the migrate tool create a new schema for me in my case (AZTECA_KSMMS), it migrates all the stuffs under that schema (AZTECA_KSMMS). However my application need the all the Oracle data under schema AZTECA instead of AZTECA_KSMMS. Is there any way to specify specific schema (AZTECA) for target oracle database? Schema remapping is available:
First Capture (separately) then during right click convert on the captured model there is a Specify the conversion options with a Object Naming tab where the schema (and other) name changes are editable.
I have not used this recently.
Also during the migration process, when I choose repository, there is a check box for truncate to reset repository to empty state, Do I need to check that truncate Check Box so the repository will be cleared from last migration?The repository can hold multple migration attempts. Check truncate to get rid of previous attempts information. This cleans up the repository - not the destination database.
There are also online database and offline database options during the migration process, what are the difference between these two choices? After I migrated to Oracle, all my views has a red cross icon next to it. Does that mean the view migration is failed or not? Please give me your comments. Thanks for your help.offline: for big (amount of data) databases with simple data types,
uses bcp + files + scripts + sqlldr.
online: for small (amount of data) databases (easier),
uses (Java) jdbc.
The view is likely to be broken - recompiling it may help.
The Oracle schema is created using a .sql file - see under generated in the directory you gave originally in the wizard. There is a .out file that contains the result of running this script including any errors. During conversion there are also likely to be warnings displayed on the UI.
There may be a single issue that is causing multiple issues - if viewa depends on functionb, and functionb is broken, viewa will also fail.
