Customer Reference regardinf Migration from COBOL to Oracle Developer

Hi,
Can anyone please share customer references regarding migration from COBOL to Oracle Developer.
Appreciate if someone can help.
Thanks,

Can you please share some tools / methodology to perform such migrations particularly from COBOL to Oracle Developer??BIG question. Actually, we did it the hard way -- completely rewrote the entire application. Took 4 years with 8 to 10 developers and analysts.
The only tools we used were what you get from Oracle: Forms, SQL Plus, Reports. It was a huge project, done partly to overcome the Y2K century problems.
AS for training, we did not really get any. We just waded in and started writing code ...which definitely improved after about 6 months.
What sort of system are you looking to convert? How much on-line user interface does it currently have? How many data files?

Migrating from Delphi to Oracle Developer Tools

We currently have a business application for financial institutions accessing oracle 8 database. However the application4s front end (the user interface), is based on Borland Delphi 5. We are interested in moving this to a web enable user interface by using the new Oracle Tools. I appreciate you to help us with some advice about how to make it easier.

Are you using JDK 1.5? If yes, there is an 'enum' type that will almost certainly be what you are looking for. If not (JDK 1.4 or earlier) do a Google on 'Java type-safe enum example'. Specifically regarding the following:
Alignment a = Alignment.RIGHT
That is fine. But normally, you do not need to assign another variable. Just use Alignment.RIGHT directly.

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.

Migrating from Sybase to Oracle

Hi!
Can someone tell me, how to migrate from Sybase to Oracle.
Thank U.

Hi,
You don't say if you have used the SQL*Developer migration workbench for the migration so far.
This has a feature for transferring data offline which should do what you want.
Have a look at the documentation linked from -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
or at -
http://download.oracle.com/docs/cd/E12151_01/index.htm
SQL Developer User's Guide - section 2.9.1 Transferring the Data Offline

Migrating from Progress to Oracle

Hi,
Wonder if someone's migrated from Progress to Oracle. What tools are available ? what are the constraints/pitfalls/limitations/restrictions ? I need to understand the overall migration process (not having done one yet). What are the tools ? what the procedural steps specifically to go from Progress to Oracle ?
If someone has done such project, I can use some highlights (if you can share your knowledge/experince).
Much appreciate any response.
Rohit.

Here is a bit of an update gathered from my own research on this issue. Hopefully, it can help someone with the same requirement as mine.
1. Oracle Migration WorkBench does NOT have support for Progress yet and according to Oracle sales, it may never be made available. Thus MWB is not an option.
2. Oracle Migration Toolkit is a possibility as it does have support going from Progress 6.x and 7.x to Oracle 7. The limitation here is that you can only go up to Oracle 7 from Progress 6.x or 7.x. In this case, I can migrate to Oracle 7 and then once all is well, upgrade Oracle to 8i or whatever.
3. The last option is, if migration toolkit does not work out, go the traditional route which is to export/extract Progress out into flat files and then load into Oracle using SQL Loader.

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 ?

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.

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

Data migration from SAP to Oracle

Can any one suggest best possible method for migrating master and transactional data from SAP to Oracle.
Please suggest methods to get data in text file from SAP.

Best approach would be to use Electronic Data Interchange (EDI) outbound from SAP inbound to Oracle. There are two widely used standards in EDI messages - ANSI X12 and EDIFACT; I'm pretty sure the Oracle system will be able to accept one of the two standards or both.
In my last message, when I asked if Oracle is able to receive and process IDocs, I actually meant if Oracle will be able to accept and process EDI messages. IDocs are containers of the EDI message i.e. a data container - their formats are SAP proprietary formats which will not make sense to your target system (Oracle). EDI has been around for many years and is the standard way of electronically exchanging business documents between computer systems of business partners, using a standard format over a communication network.
In regards to your question - I'm not really sure if you want to send master/transactional data real-time from SAP to Oracle or want to transfer the historical data i.e. download from SAP tables (thru SE16 - this will download the field labels as well) into text files and then upload it to Oracle by using a custom program which reads/maps the files then posts the transactional data/updates master data tables in Oracle as required by that system. So let me know as much details as possible.
It would be nice to show appreciation by rewarding points.
Cheers,
Sougata.

Experiences migrating from Sybase to Oracle

Hi all,
I have been asked to look into migrating a database from Sybase to Oracle.
I know there is lots of info on Oracle's website, which I have downloaded, but I was just hoping for some info about some of your experiences regarding your processes. What are the gotchas. I suspect there will be a few.
Anything that will help would be of interest.
Many thanks
VicC

HI VicC,
I work within the SQL Developer team and not a customer as such, but the follow maybe of use.
SQL Developer is a migration aid, its not 100% magic bullet.
SQL Developer does alot of the manual conversion for you quickly. But you may find Testing / Tuning and the application migration (if any) take you the most amount of time.
SQL Developer aims to migrate you tables, indexes, and data without issue. But SQL Objects like Procedures, Triggers, Views and Functions conversion will likely require manual work on top of the automatic conversion provided by SQL Developer.
SQL Developer does not yet automatically handle things like the tablespaces structure or the the logins. Although these things can be scripted and managed more easily within SQL Developer.
I would recommend downloading and performing the migration from a non production instance ASAP.
SQL Developer can perform a migration quickly and you will then be able to assess what SQL Developer can and cant do for you.
I would recommend creating a migration repository on an Oracle database local (install Oracle XE if you dont have a local database) to the SQL Developer instance you are using.
I would also recommend downloading SQL Developer 2.1
Here are some key sites regarding Sybase migrations.
http://www.oracle.com/technology/tech/migration/workbench/viewlets/sqlserver.html . This viewlet for SQL Server is the same process for Sybase.
http://www.oracle.com/technology/obe/hol08/sqldev_migration/sybase/migrate_sybase_otn.htm . This Oracle By Example takes you step by step through a Sybase migration including some gotchas
http://dermotoneill.blogspot.com/2008/06/sql-developer-migration-workbench-151_11.html . This is my blog outlining the steps to perform a Sybase migration.

Migration from Informix to Oracle

Hi,
Could anybody share the case studies/plan/docs related to migrating data from Informix to Oracle.

Hello,
The Oracle® Migration Workbench Reference Guide for Informix Dynamic Server Migrations is avalaible at
http://download.oracle.com/docs/html/B16022_01/toc.htm
Also, you will find a lot of informations on the Informaix migration technet page at
http://www.oracle.com/technetwork/database/migration/informix-085032.html
Even if a lot of samples are Microsoft SQL Server based, they also apply on an Informix migration as well.
Hope it will help
