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 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 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.

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)

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 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.
Message was edited by:
user596259

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 MYSQL database to Oracle database

HI,
Can you pls let me know how can we do this using Oracle SQL Developer.
In Mysql database we are having one table which is not normalized and corresponding to it we have created normalized tables in oracle database.
so scenario is like this
EMP table in MYSQL database ----------- need to migrate to----> Employee table
Dept table.
These tables are having some extra columns also which are not there in EMP table in MYSQL database.
SO we want to fill some default values for the new columns while doing the migration.
Can you pls let me know if this is achievable through SQL Developer and how?

Sorry, you'd have to do this in 2 steps:
1. Migrate the tables as they are.
2. Insert the rows from the migrated tables into the new ones.
Have fun,
K.

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

Migrating from Pick Database to Oracle 8i database

We are investigating the possiblility of exporting the entire contents of a pick database into an Oracle 8i database. Can you suggest any resources needed or utilities needed to perform this?
thanks in advance
warren

If Access2000 allows you save the database as an access97 database then you can use the Oracle Migration Workbench to do the conversion. Sorry, Im not the Access expert so I can't say for sure whether the save as 97 option is shipped with 2000. I'll look into it and post a definitive answer tomorrow.

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:
