Migration from DB2 to Oracle 10g using free tools

Dear all,
Im currently using DB2 database and wish to migrate data over to Oracle 10g express. However, i could not find any free tools or methods to migrate without using tools as i could not use tools like Oracle Migration Workbench as the migration is for certain project which will deal with internal process or commercial purpose.
Would like to seek everybody's help. Greatly appreciation your response.
Regards,
Kee Cheng =)

Thanks. But have you heard of creating a heterogenous services, create a database link between the 2 database, then transform over to Oracle?I thought you were looking for a free tool. With HS, you'll have to buy the component to install on the DB2 system. Unless something has changed since the last time I worked in a mixed Oracle/DB2 shop.

Migration from DB2 to Oracle issue

Hi
I'm migrating an old legacy system from DB2 to Oracle but have the following trouble:
The queries that the app executes have some DB2-specific syntax such as DATE function, example:
select * from TABLE where date_col > DATE('2010/01/01');
The above query works on DB2 but not in Oracle (should be changed to use TO_DATE function but this is not possible initially)
I could create a function in the Oracle db called DATE, something like:
create function date (p_date varchar2) return date is
begin
return to_date(p_date)
end date;
create public synonym date for sys.date;
But DATE is a reserved word and I can't use it as function name
Do you know any way of making the above query work against an Oracle db or transforming the query text before being parsed?
Thanks a lot in advance
--Guillermo

As you stated and mentioned in the manual:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10830/appb.htm
DATE is a reserved word and thus you need to recode the statement. For example the migration utility is commonly adding an underscore to the function - and this requires again a recoding of the source statements.

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

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.

Wolfgang

DB Migration from SAPDB to Oracle 10g - Archive access after migration?

Hi!
Our customer plans to move his SAP system landscape from one Service Provider to another. During this not only new hardware is used but also a DB migration will be done using the procedure described in the SAP System Copy Guide (SAPDB -> Oracle - Offline Export in source system,
Import in target system).
SAPSID and client will be the same in the new environment, but of course HW key, IP-adress, Server name, Domain name and obviously Installation no. will change. SAP Note 153433 as well as System Copy Guide do not completely clearly tell me, whether we will face problems when trying to access our archived data after the migration. It's not completely clear to me, how the Archive References are
built: Only using SAPSID and client? Then everything should be okay, because here we plan no changes.
So do we have to face any problems when trying to access and/or reload the archived files and objects after the movement to the new service provider? Are there any pitfalls concerning archviving and archive access we have to take in mind?
Add. info: The archvied files and objects are stored in an IBM Common Store which will be moved physically from location A to B. So here nothing changes.
Thanx in advance for any hint.
BTW: SAP Notes 153433, 460620 and 53068 were already studied. SAP support said this is a consulting issue ... ;-(
Regards,
Volker Kolberg

Hi Volker,
I haven't worked much on archiving, however Archived files are flat files ( I think) and hence these files should be common for all databases.
However a good strategy is to first test. I think you must have already thought about it however still here is what you could do.
Take system copy of the system you want to migrate ( you could choose a development system where there is not much data)
Delete data the production clients in the copied system.
Archive some data using object something like WORKITEM which is harmless workflow object.
Migrate the system and try to reload the object
Hope that helps.

Help on Migration from DB2 version 8.1 to Oracle 10g

Hi All
We have one requirement of migrating one Mainframe database to Oracle 10g. the DB version is DB2 8.1 on Z OS. We are thinking of using Oracle Migration workbench. Can someome help me know if this is supported by OMWB tool or not. I checked in oracle site, they have mentioned some details about V4R5. Could not conclude. Please confirm this. Also let me know if there is any tool that we can use or we have to go manually. Any pointrs would be highly appreciated.
Thanks,
Prashant

OMWB nor its follow up product SQL Developer Migration workbench support DB2 z/OS migrations. You have to do them "manually".
For a manual migration you might use an Oracle Gateway which allows you to use an Oracle database link to the Db database and you can then use the gateway to copy the data from Db2 to Oracle. Another alternative would be to unload the DB2 data into an ascii file and to load it into the Oracle database using SQL*Loader. You might also use Golden Gate which is commonly used to replicate data between Oracle and DB2 - but it allows you also to use it as a migration utility.
There are also Oracle partners that can assist you with the migration - please have a look at:

Licensed version and free download from OTN of Oracle 10g DB

I had a doubt with any difference with the licensed version and free download from OTN of Oracle 10g DB. We had downloaded a free version of oracle 10g
database from OTN and are using it in our live environment. It seems to be working fine. We are trying to get a licensed copy of Oracle 10g DB also but that may take sometime. So, my doubt is whether the free download from OTN should not create any problems in our live environment.
I hope, my question is clear.
Please, help in solving the doubt.
regards

Hello,
There is no difference whether you download from OTN or get so called licensed copy of oracle software. It's free to download and free to use you are using for personal eduction purpose, but if you are using for commercial purpose then you should contact oracle sales for pricing but you can continue with the same software. See following link for certification on different platform

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.

Problem while migrating from Sybase to Oracle using Quick Migrate

Hi,
For SQL Developer version 2.1, while migrating from sybase to oracle, Using Quick migrate, during data move step, for the rows having ''(Blank) values in TEXT data type in SYBASE, which is convertd to CLOB in Oracle, the migration for that table terminates at that row.
However, NULL values in Sybase TEXT data type are successfully inserted in Oracle CLOB.
How can we overcome this?

reproduced and see exception in console, bug logged.

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 ?

Hotkey (Ctrl+B) is not working after migration from Forms 6i to 10g

Dear Gurus,
Need your help regarding the following problem:
After migrating from Forms 6i to 10g (Rel 2), Ctrl+B (used to list the blocks in a form) hotkey is not working anymore (all other hotkeys are working fine). I've checked my FMRWEB.RES and it contains an entry for Ctrl+B:
66 : 2 : "Ctrl+B" : 70 : "Block Menu"
Additional Information:
OS: AIX
NLS_LANG = UTF8
fmrweb_utf8.res also contains the same text for Ctrl+B as above.
I tried to reproduce it on my Windows Machine (with NLS_LANG set to AMERICAN_AMERICA.WE8ISO8859P1) and its not working as well. I don't have right to put move files on AIX server but i can try anything (on my local system) suggested by the Oracle gurus.
Best Regards,

Dear Gerd,
"are you sure, that it is the hotkey"
Yes, i am dead sure. Since:
(1) It was working fine in forms 6i
(2) If you run a form and select Help => Keys, you will see Ctrl+B on the top of list
The problem is its not taking into account the keys which i am defining in the file (although i am following the same procedure detailed on metalink.oracle.com).
