Altering database during migration from MS Access 2000

Hi to all Oracle forum members.
I want to migrate a MS Access 2000 database to Oracle 9i release 2. I want to know how can I alter the database design during the migration progress. My plan is to split an existing table to more and re-arrange the data and maybe introduce some new tables as well. These changes cane be made using the Migration Workbench or after migrating to Oracle? What is the most efficient way to do that and how can I accomplish these changes?
Thanks in advance...
A desperate new Oracle user... :)

Hello patriotaki! I used Oracle Migration Workbench and everything seems to be fine..just take care on code page migration isssues ...have fun!!!

Error while migrating from ms access 2003 db to oracle 10g in sqldeveloper

Hello,
i am working on migration project from MS access 2003 to Oracle 10g on windows XP sp2 plateform using SQL developer.
it went quit smoothly till the "capture microsoft access" .so in this step the sql developer opens the access db in background... but while opening the file in background it gives error
Object library not registered i tried many workaround but of no use..
anybody's help in this regard would be well appreciated.
thanks.

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

Hi Akhil,
Looks like some Tuxedo services are using Pro*C code. Therefore, you would need to recompile your Pro*C code using the newer compiler and then rebuild the Tuxedo servers.

Problems with german umlauts when Migration from MS Access to Oracle

When I make a Migration from MS Access 97 to Oracle 8.1.5, I have Problem with the germans characters (umlauts). The Oracle is using the rigth character Set for german characters. What can I do? Is it e problem from the MS Access ODBC Driver or the Oracle ODBC Driver?

Is your character set for Oracle set up to UTF8??

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

Problem with some queries after migration from MS Access

Hi everyone!
We've just finished a migration from a MS Access database and we notice some errors when running some queries like :
Query1:
SELECT A.field1, A.field2, B.field1 as FieldTmp
FROM A,B
where (B.field1 <=10);
Query2:
SELECT Query1.field1, Query1.field2, Query1.FieldTmp
FROM Query1 LEFT JOIN Table3
ON (Table3.field1 = Query1.Field2) AND
(Table3.field5 = Query1.FieldTmp)
WHERE ((Table3.field5) Is Null)
ORDER BY Query1.field1, Query1.FieldTmp;
The Query1 runs as expected, but when I try to run the Query2 I got a ORA-00904 error message. If I remove the (Table3.field5 = Query1.FieldTmp) statement or modify to compare with another field (as instance, field2) everything goes fine.
If I modify the first query to a make-table query, the Query2 request runs as desired too.
Is there anything that we can do to keep the queries statement as it is when using the MS Access DB?
Thanks in advance,
Elaine Viel Denadai

Hi Turloch! Thanks for your help!
Those SQL Statements were extracted from the MS Access application that we will continue to use to access the data , now on an Oracle Database.
I don't know what I can do to make this kind of statements works as it is on Access database. The first query, that I called Query1 works fine on Oracle, I just mentioned it because the 2nd Query , named Query2, use it.
I'm not able to understand why when I change the 1st. query to a "make-table" query the Query2 works as desired, but if I keep the Query1 and Query2 as it is on the MS Access Application I got the ODBC error message and the ORA-00904 error message , related (I think!) to the FieldTmp field used on the LEFT JOIN statement (AND).
As I told before, if I change the AND clause to compare to another field, as instance, field1 :
FROM Query1 LEFT JOIN Table3
ON (Table3.field1=Query1.Field2) AND
(Table3.field5 = Query1.Field1)
it works.
Please, is there anything that I can do to keep the MS Access Application unchanged?
Oracle = 8.1.6
Oracle ODBC Driver = 8.1.6.4
Oracle Migration Workbench = 1.3.1
Thanks in advance,

Migration from MS Access 2003

Hello,
I'm very new to MS SQL Server; I just downloaded Express 2005 yesterday. I have it up and running; it seems to be working fine.
Now onto business - I need to migrate data from existing MS Access 2003. How, exactly, do I do this? I've tried searching MSDN, TechNet, and here, and while I get results that seem to tell part of the story, I don't seem to get a true "How to" for this task.
Can someone please assist me with this?

Migration from MS Access to Oracle 8

Sir,
I have exported the MS Access table from MS Access to Oracle in the following way.
I have selected the table from MS Access and clicked on export and then it asked for exporting option. I have selected ODBC databases and given the option from 'emptab' to emptab. I have created a new system dsn and finally the table was exported to oracle(user name: scott pwd : tiger. when I logged on to scott/tiger and queried the tables select * from tab; , all the tables in that user are displaying. But I am not able to query on that particular table. I was getting the message 'table or view' doesn't exist. Pl guide me how to access that table and query on that table either desc table or insert into that table or update etc.
with warm regards
[email protected]
srinivas

Srinivas,
The Oracle Migration Workbench will migrate access data and datastructures over to oracle, it can then modify the access database so that link tables are created to access the oracle information from the access forms and views.
If you are using ODBC to export the data:
What are the commands you are entering and the output? Note that oracle tables are usually upper cased so if the table name is MY_TABLE, select * from "my_table"; will not work whereas select * from my_table; will. Access export via odbc preserves the case so one may need to select * from "my_table";
select table_name from user_tables;
Will show the current users tables, to show what case is expected, upper or lower.
I hope these small pieces of information are helpful in solving the issue.

Turloch

How to alter database character set from AL32UTF8 to EE8MSWIN1250

Hi folks,
I'm using an Oracle 10g, XE database, which has a database character set set to AL32UTF8, what causes that some characters like "č ť ř ..." are not displayed.
To fix this issue, I would like to change it to EE8MSWIN1250 character set as it's set on server.
Unfortunatelly below steps don;t work for me:
connect sys as sysdba;
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER SYSTEM ENABLE RESTRICTED SESSION;
ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
ALTER SYSTEM SET AQ_TM_PROCESSES=0;
ALTER DATABASE OPEN;
ALTER DATABASE NATIONAL CHARACTER SET EE8MSWIN1250;
ALTER DATABASE CHARACTER SET EE8MSWIN1250;
SHUTDOWN IMMEDIATE; -- or SHUTDOWN NORMAL;
STARTUP;Value in regedit: HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\KEY_XE is set to CZECH_CZECH REPUBLIC.EE8MSWIN1250
I'm struggling with this issue for hours and unfortunatelly can't make it work. Any advise is more than welcome.
Thanks,
Tomas
I tried to use hints listed here , but always getting some ORA messages.

Hi Sergiusz,
Thank you for your reply. You're right, I've probably didn't provide a full details about my issue, but at least now I know, that database encoding(characterset) is correct.
Here is my issue:
Within my APEX application I would like to use a JasperReportsIntegration, so to be able to create and run iReports straight from APEX application. Installation, and implementation of JasperReports works fine, I had no issue with it.
As a second step I've created a simple report using iReport tool, when if preview function is used, all static characters (from report labels) are displayed correctly. Database items are displayed incorectly - some Czech characters are not displayed. Language within report is set to cs_CS, but I've tried also other options. No sucess.
When I run that report from APEX application (from server) then the same issue - data from database are returned without some czech characters.
Kind regards,
Tomas

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 -

Screen went black during migration from time machine backup

Just did a clean install of Mavericks on my wife's 3-year old MacBook Air. I erased the hard disk first from the Recovery drive. Then did the Maverics install. All went well. Then I started a Time Machine migration from a back up I had on a Toshiba HD. Everything started well showing about a 2 hour back up time, but about 1 hour into the migration, the MacBook screen went black. I couldn't get it to go on, so I did a hard reboot of the system. I've had to start the migration again, but not I'm concerned the same thing will happen.
Any ideas what is going on?

You can also go to System Preferences/Energy Saver and set Display sleep to never until you are done, then reset it.

Error during migration from Windows 2000 to RH Linux AS 4

Hello all,
Am trying to perform a migration of a 11.5.10 instance from Windows 2000 to RH AS 4. Am following steps listed in the doc id 238276.1.
Have completed all steps, but autoconfig completes with the following error:

Migrate From MS Access 2003 to Oracle using Oracle SQL Developer 3.0

Hello All,
I am trying to migrate Access DB .mdb using the Oracle SQL Dev 3.0 Data Migration Wizard, everything go very nice and smooth until the Capture Step, for sure am using the online mode, in the Capture Step the list of available databases is empty and a Msg Box saying that the DB list should have at leats one database selected, so I don't know what's that mean or how to fix this.
in my .mdb file I have four tables and I can copy the data to Oracle using the Right click and copy to Oracle Function, but it really takes much time.
Any help would be really appreciated and thanks in advance.
yours,
Hussein

Just to clarify:
You have created the migration repository and start the migration using Tools => Migration => Migrate
- now you've selected the repositiry
- specified a project
- selected the source database
=> you've choosen the ONLINE Mode
==>> and now you don't see your MS Access database in the "Connection" List
Is this correct?
If the steps you're doing match the steps I've posted above, then please be aware for MS Access migrations you need to choose the OFFLINE method. The MS Access source database information is collected by the MS Access Exporter available from Tools => Migration => MS Access Exporter
Once you've created the XML/OCP file you specify this newly created file during the OFFLINE migration mode.
If your steps differ from mine, please post yours more detailed.
Thx.

Problem during migrating from weblogic to oracle9iAS, .......urgent

Hi all
I am migrating my application from weblogic 7.0 to oracle9iAS Release2 Version 9.0.2.
My problem is:
In my application, after an entity bean creates a row in the table, if there is any SQL update or insert in the same transaction for the same table to which the entity bean created the row, Oracle9iAS could not proceed with the transaction(it is locking indefinitely the stored procedure which is either updating or inserting).
After analysing the problem,i found that this is working in Weblogic because of the following parameter in the weblogic-ejb-jar.xml.
<delay-updates-until-end-of-tx>false</delay-updates-until-end-of-tx>
The function of the above parameter in Weblogic is:
Setting delay-updates-until-end-of-tx to false does not cause database updates to be "committed" to the database after each method invoke; they are only sent to the database. Updates are committed or rolled back in the database only at the conclusion of the transaction.
My question is Is there any such parameter or its equivalent in oracle9iAS or is there any way to get out of this problem. This is very urgent for me......plz help me out.
Thanks in advance,
Siva Kishor

Hi,
The tag (delay-updates-until-commit) you have suggested was not compatiable with oracle9iAS 9.0.2, It is giving "Counld not recognize "delay-updates-until-commit" in orion-ejb-jar.xml during deployment of the jar.
So we have migrated our application to oracle9iAS 9.0.3. Now we are not getting any such error during deployment but while using the application to insert/update getting Null PointerException.
This problem may be related with some migrating issues of Oracle App server(9.0.3).
But at the same time this can be related with EJB's coding also since this new version
of Oracle App server is compatible with EJB 2.0, our application has been developed using EJB1.1 Spec.
This is the stack trace, during accessing EntityBean.
