Migrating from Sybase 11 to Oracle 10G : Data not Captured

Hi,
We are working on an interesting customer engagement - one part of the effort is to migrate our Customer's Database. Our Customer is using the Sysbase 11 Database - we are planning to migrate this to Oracle 10G.
We are using the latest Migration Workbench - 10.1.0.4.0. We created a new user in one of our local DB Instances & used this credential to login to the Migration Workbench tool. We have the Source Files for the Sysbase 11Database.
We tried to capture the Source Model - unfortunately, the Tool claims that the Objects have been migrated, while the Source is not captured at all. The Error Log is alos silent about any problems.
We are flummoxed by this error as we have successfuly migrated from Sysbase in the past, but never encountered this error.
Can you guuys please help us out with this ?
Please do let me know if I need to post more information
Thanks,
Sandeep

Sandeep,
Have you used this user which holds the omwb repository before for a migration? When you connected the first itme, did you get a message, that the repository tables did not exist and would you like to create them?
Are you using the connected or disconnected source model load?

Migrate from redbrick database to oracle 10g

Hi Folks,
Does anyone of you did a migration from redbrick database to oracle 10g please help me out with the steps to do that? I tried to search for a document with no luck.
Appriciate if you could point me to a doc or a white paper that talks about the migration.
Thanks in advance.
Karthik.

Red Brick is now part of the Informix family, maybe the migration workbench helps:

Migrating table from Sybase 12 to Oracle 10g

Hi ,
We have a situation where we have to migrate multiple Sybase databases to Oracle10g . These multiple database have same set of tables but different data in these tables on each sybase database ( data differ, based on location or region wise but same table name and structure). We want to migrate all these sybase database to Oracle 10g and in single database, which involves inserting data from multiple tables ( though they exist on different database in sybase) into single Oracle table.
for example if we have a table 'TESTK' that exist on five different sybase database but with different region wise data. I want to bring data from these five tables( Five as they exist in five differet sybase databases) and insert them into a single oracle table 'TESTK' .
Have anybody ever face such scenerio , what are all possible approch please suggest. Once data is inserted into oracle table i need to partitioned this oracle table as well.

It is not quite clear whether you have multiple tables (referencing each other) in multiple sybase databases or either one table or several non connected tables in multiple sybase databases.
In the first case of course your task is harder because you need to keep references and most probably you cannot blindly copy data from db 1, db 2 and unite them because they can have the same id's coming from different sources.
In the second case your task of course is much easier you can simply load all your data in Oracle tables either using some interim tables (if you need to filter out duplicates) or load data straight into target tables if you are sure you haven't duplicates.
Also another question in case 1 is whether intersection of your data is 0 rows i.e. all data are completely different in each source db or not.
So I'm sure you can find tools for blindly moving data from sybase to Oracle, although if you need to do some more complex filtering, computation or whatever you most probably need to write it yourself.
I'v done a few data conversion projects from one schema to another and as the requirements were quite complex the only possibility for us was to initiate a separate data conversion project and create conversion software (pl/sql packages manually).
You can find an overview of our approach in my article "Data migration from old to new application: an experience" here http://www.gplivna.eu/papers/legacy_app_migration.htm

Migration from sybase 11 to Oracle 9i

Hi,
I have to migrate all db objects (tables structures,table data,triggers,sp) from Sybase 11 to Oracle 9i
There are currently two free tools -
Migration workbench (http://www.oracle.com/technology/tech/migration/workbench/index.html )
and
SQL Developer( http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html )
for this purpose.
SQL developer has a provision to convert scripts which I can use for SPs and scripts one @ a time.
Problem is migrating table structures along with data.
from SQL developer I can't connect to sybase thou I provide all the details and from workbench in the online mode I need the sa login which is not possible as the database is live and @ client side.
SQL Loader can be used but will require to make CSV files from each sybase table and hence is time consuming.

Hi,
Migration Workbench is not available for Sybase database.
As you can see on this website:
http://www.oracle.com/technology/tech/migration/workbench/files/mig_rel10104.html
Only Informix and DB2 database are supoprted now with this product.
With SQL Developer, we only support last versions of Sybase : V12 and V15.
As you don't have any remote access to your client database and no SA login , the best way would be :
==>to get and export from Sybase 11.
==>install a V12 somewhere (on your site , you can download the Sybase V15 )and import the Sybase database
Then SQL developer can migrate quickly your database without any problem.
I hope it helps you.

Migration from Sybase 11 to Oracle 8i

I am trying to migrate a Sybase DB to Oracle 8i. The platform of Sybase system is VMS and Oracle is UNIX. Can I use workbench to migrate between two different platform?
If not, is it the only way to export sybase to a flat file and then load to Oracle using SQL loader?
Thanks

Migrate Data action hanging migrating from sql server to Oracle 10g

Hi,
I am currently migrating a SQL Server 2005 db to Oracle 10g using SQL Developer 1.2.1. I have created the migration repository, captured the SQL Server db objects, and created the target schema. There are about 109 tables captured. During Data migration, however, the data move hangs. I have run the data move a couple of times now and it does not hang while migrating any particular table, but seems to be more to do with the length of time it is taking to migrate. Could this be an issue with SQL Server connections being lost? The SQL Server db is quite large. Row counts of 100k plus.

Probably. There is an offline option for migrating data under the migration menu. Generate Scripts for the data move using the appropriate converted model and u can export the data to bcp export files and load it with teh generated SQL Loader scripts.

Migration from Sqlserver 2005 to Oracle 10g

Hi all,
does anyone know a tool good to migrate a sqlserver 2005 database to oracle 10g ?
I tried Sqldeveloper and the migration of tables and datas are ok, but when I try to migrate views, functions and procedures the sqldeveloper hangs.
regards,.
Wander (Brazil)

Quite frankly forget using tools for all but the simplest migration: The best you will get from a tool, provided it works, is mediocrity.
Moving tables and data with tools works if you are using basic data types. Once you get past this, in all seriousness, it is time to roll up your sleeves and start writing code.
The differences between the two products is profound. What constitutes a transaction different, locking different, logging different, security models different, etc.
No tool can turn Transact SQL into nested BULK COLLECT and FORALL statements. And for many years into the future ... none will.

Migration from MySQL 5 to Oracle 10g

Hi All,
I'm currently trying to migrate a MySQL database to Oracle and have encountered a few issues, it appears to work fine for most of the tables, with a few errors occurring in the logs for other tables, but they look to be related to connection issues that I am encountering. Both the MySQL and Oracle Database are installed locally on my machine. Below is the exception. Any ideas why the migration would be working perfectly and then encountering the below problems?
Any help would be greatly appreciated. Thanks in advance. Also, should anyone need any further information regarding my system setup etc. don't hesitate to ask.

Hi,
Unfortunately now I am receiving a slightly different error, relating to the connection being closed due to a seemingly bad response from the MySQL server, where it expected a larger value than received. I have updated the Third Party JDBC drivers to the latest available.
The connection appears to drop and stop the data migration process, and it appears that this has stopped sooner than my previous attempt. Any help/advice would be greatly welcomed. I'll continue to investigate this on the web, but would assume this is the best possible resource for resolving these kind of problems.
Below is the stack trace received in the migration logs:
It is a particularly large one (sorry)

Migration from SQL 2000 to Oracle 10g

Hi every one,
This is the first i am posting to this forum.
I have a problem in migration of Sql Server database to Oracle 10g.
We use Microsoft Navision Axapta 3.0 SP4 as front end.
and Sql Server 2000.
All table and indexes are created in sql server by Navison only.
My Database size is 300 GB and now we face thousands of Problem with SQL server so we decided to make a intelligent move to oracle 10g.
As we have 1200+ users.
The problem i am facing when i tranfer all the table to my Oracle Database it gives a error out of buffer.
some time it gives me error about the index as few of our developer have create two indexex on one field.
So oracle identifies that there are two indexes on one field.
So pls help how can i solve this problem.
I have 1234 tables.
from
Mohd Sufian

Can you post the exact Oracle error you are getting? The ORA-xxxxx part is the most important for us to identify what particular problem(s) you're having.
Is your front-end certified to use an Oracle database? Particularly if the front end is creating database objects, it needs to know how to work with whatever database it is connecting to.

Migrate from DB2 7 to Oracle 10G(R1)

Hi, all.
I have a big DB2 db. When Oracle and DB2 set up on different computers, OMWB works good. When i install Oracle and DB2 on one system UDB7 driver not work - on step "Source Database details", when i enter user ID/pass and database name, then do nothing :(.
How explane it?
User information correct. DB2 ODBC driver - worked...
Can you help me?

Are you missing a zip file, or are using an unsupported by omwb version of the zip file/driver?
That is what is suggested by a java.lang.NoClassDefFoundError found message from Java.
It is also possible, but less likely, that some corporate anti-virus/security software has changed the software. There was a post concerning that possibility recently months ago. [search for www.trend.com on this forum: Urgent help-Unable to login into OMWB
Posted: Jan 30, 2007 11:23 PM]
From the User Guide:
Before Migrating From IBM DB2 UDB
To configure an IBM DB2 UDB database for migration:
1.
Install the IBM DB2 UDB Client software on the same system as Migration Workbench.
This automatically installs the IBM DB2 UDB JDBC driver contained in the db2java.zip file.
Note:
Migration Workbench supports the use of either the JDBC 1.2 or JDBC 2.0 compliant IBM DB2 UDB JDBC driver.
2.
Copy the db2java.zip file to the following directory:
OMWB_install_dir/Omwb/drivers
3.
Make sure that you can login to the IBM DB2 UDB database with a user name that has database administrator privileges.

Migration of next_identity() from sybase 12 to oracle 10G

Hi,
What is the oracle equivalent for next_identity() in sybase.
Thanks and Regards,
Vinoth Kannan

Hi Vinoth,
The OMWB does not migrate this function automatically.
next_identity() returns the next value to be used in an indentity column. You pass it the name of the table as a parameter. Example
T-SQL
SELECT next_identity(table1)
if table1 does not have an identity column then null is returned, otherwise the next identity value for that table is returned.
Oracle does not have identity columns, so the OMWB will migrate identity columns to a sequence and a trigger. This sequence will named SQ_<IdentityColumnName>.
So to emulate
next_indentity(<table_name>)
you may have to go
SQ_<IdentityColumnName>.CURRVAL + 1

Dermot.

Migration from SQL server to Oracle 10g

Hi, I am new here,
I would like to ask how to use SQL developer MWB to migration SQL Server to Oracle?
I have go through the doc(s) like: getting start, user's guild, etc. and have following problems
(1), where should the SQL developer installed? in SQL Server side? Oracle side? or any PC with connection to the databases?
(2), do I need to get some plug-in(s) for MWB to work? If yes, which plug-in do I need and where are they?
Thank you very much.

Hi Chocobo,
I put together a Quick Guide myself

Migration from SYBASE IQ to SYBASE ASE 11/12 and then to ORACLE 10G

Hi ,
The OWMB tool does not support migration of SYBASE IQ to ORACLE.So there should be some tool to migrate this SYBASE IQ to SYBASE ASE 11/12.And then which we can migrate to ORACLE which the OMWB supports.Does anybody have any idea about such tool(SYBASE IQ to SYBASE ASE 11/12).
Thanks With Regards,
Vinoth

Vinoth,
That's correct. However Sybase IQ is normally associated with Data Warehouses. Have you investigated the suitability of using Oracle Warehouse builder to assist with such a migration?
Ispirer supports migration from Sybase IQ 12 ( http://www.ispirer.com/products)
