Migration from DB2 on mainframe z/os, os/390

Hello,
we are planning to perform a migration from DB2 on a mainframe towards Oracle. I've read about the Oracle Migration Workbench I didn't find anything that states that a migration from mainframe can be performed with the Migration Workbench.
We only want to migrate the DB2 tables towards a staging environment (in Oracle), so we only need to migrate the table definitions with the data.
Can this be done with the migration workbench?

Arno,
The Migration Worklbench does not support migration from DB2 on the mainframe currently. support for this is under development. If you would like access to this you need to get in contact with your local Oracle account team to progress.
If all you are interested is tables/data this can be achieved via our gateway products.
We also have gateway support for DB2 natively. You will find more information about that here:

Migrate from db2/400 (V5R2) to Oracle

Greetings!
We are looking at helping a customer migrate their DB2/400 (V5R2M0) database to Oracle (planned for 10gR2).
I see there is a Migration Workbench offering for the lower revisions (v4r3) as well as for DB2/UDB, however nothing for V5R2M0.
There are over 1500 files (tables) to convert so we don't want to have to do a dump & load.
Any suggestions?
Thanks!!

Jim,
I work for a group in Oracle Server Technologies that focuses on legacy (mainframe and midrange) modernization. There are three options from Oracle:
1. Oracle Data Integrator (was Sunopsis) - This product is completely written in Java so it can even run on the iSeries/AS400. http://www.oracle.com/technology/products/oracle-data-integrator/index.html
2. Oracle ransparent Gateway for DB2/400 - Can execute qeuries directly against DB2 to migration the data. http://www.oracle.com/technology/products/gateways/tg4db2400.htm
3. OWB (Oracle Warehouse Builder) - This is an ETL offering from Oracle. Two options for moving the data FTP (and load the flat files) or if you have an ODBC driver on the iSeries can use this with OWB. http://www.oracle.com/technology/products/warehouse/index.html
Hope this helps. My team is hear to help with legacy modernizations so don't hestitate to contact me at [email protected]

Migration Workbench for migrating IBM DB2 on OS/390 to Oracle 10Gon Solaris

Hi,
We are looking to migrate an IBM DB2 database on OS/390 onto Oracle 10G on SUN Solaris. Can anyone help us with a migration workbench toolkit for the same.
Regards,
Jagdish Narayanan

Jagdish,
We don't currently support migration from DB2 on the OS/390 platform. If you need a solution now, you might investigate a solution from one of our migration partners like Ispirer: http://www.ispirer.com/products/

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:

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.

Windows to Linux migration

Hello,
I'm interested in performing a move of our ZCM 11 primary server from the
Windows 32 bit platform to Linux running 64 bit. Does anyone know where
I might find any documentation of guidelines on this process?

Whilst you say you want to move your "ZCM 11" server what's the exact
version of ZENworks that you're running?
Am I right in thinking that the move to 64-bit may be related to wanting
ZENworks 11 SP3?
Which OS (and version) do you have in mind for your (target) Linux server?
Whilst ZENworks only supports migrations between servers that have the
same OS (so Windows Server to Linux is not supported) that doesn't mean
it's not possible. Knowing the current and target versions will help us
advise further.

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.

Linux Migration 11.5.10.2

We are planing moving our 11.5.10 with 10g RAC from Solaris to Linux, and I would like to hear from anyone who's done it already this kind of OS-OS migration, or knows of any good white papers which discuss it.
I have gone through my Threads in this forums but i did not see anyone discussed on RAC Migration.

Hi Chrle,
Could you please refer me any metalink documents to check pre_req's in new servers for RAC installation.This is covered in the installation document (which can be found in the link referenced above).
Not sure what Linux version you are planning to use, but if it is OEL/RHEL 5 then you could also refer to:
Requirements For Installing Oracle 10gR2 On RHEL/OEL 5 (x86) [ID 419646.1]
10gR2 RAC Install issues on Oracle EL5 or RHEL5 or SLES10 (VIPCA / SRVCTL / OUI Failures) [ID 414163.1]
Thanks,

Windows to Linux Migration advantages for 10gR2 database

Hi
My client currently on windows environment,
now they want to migrate OS to linux.
So kindly help me to identify the advantages of migration to linux.
Regards
Shaik

Security wise what are the advantages available in Linux comparing with windows?Not to say that Linux is not targeted. But the basic advantage is that less attacks are aimed at Linux, than Windows. The latter is the de facto desktop o/s and as such is the taller tree that catches more of the wind and weather.
Besides that, both o/s's needs hardening after installation. Like Windows, Linux has a feature set that protects privilege programs against attacks (data/code injection) by unprivileged programs. It is called SELinux where SE stands for Security Enhanced.
Linux's default firewall is iptables and IMO a far better piece of software than the default Windows firewall. I even use iptables as a NAT load balancer for RAC.
How good security is, is however not about how "good" the o/s is. It is about how well you understand the risks. It is about how well you address these risks.
In other words, the only safe server is one without a stiffy drive, tape drive, DVD/CD drive, without any NICs, locked in a vault and thrown into the Puerto Rico Trench in the Atlantic ocean. ;-)
Any specific advantages are there for maintaining oracle database on linux environment?That would be a major issue in my environment. The Oracle servers I support are scattered across a very wide area and 1000's of km apart.
I need things like access (via various firewall) to Oracle servers, the ability to tunnel connections, persistent console sessions, a means to run GUI programs, powerful shell scripting, the ability to dynamically load and unload kernel drivers and a host more...
And Linux does this the best for me.
Disadvantages of windows for maintaining oracle database?That again depends on your environment and requirements. There are many Oracle sites that are very happily running Windows.
In my environment - Windows would be a major limitation. For example, in order for db-to-db connectivity across networks I've written a shell script that creates a tunnel between these servers, and configured that script as a kernel respawn daemon - meaning that should the tunnel die and script terminate, the kernel will detect that and auto restart the script. (Oracle RAC's high availability daemon is run the same way on Linux)
To do this in Windows? The Windows o/s is like a car with the hood of the car welded shut. So it requires a lot more effort to get certain things done and working. With Linux this is not the case. Heck, you can even build a kernel that are custom tailored for running your Oracle database and storage/network/interconnect drivers and nothing else. With Windows, just changing the HAL is a big deal.
The usual reaction I get when saying that we use Linux is along the lines of "+Linux is not as robust and scalable as heavy weight commercial o/s like Windows or Solaris or <insert-name-here>+".
And in actual fact, the reverse is true. The only robust and scalable o/s on this planet is Linux - if we go according to Top500.org that lists the o/s families of the biggest, baddest and fastest super computers in the world. 459 out of these 500 are running Linux. That is 91.8% of the world biggest and fastest clusters. A mere 5 (1%) are using Windows.
Bottom line is that Linux is more than just capable. It is not inferior to Windows - especially not when vast majority of the most advance computer systems in the world are running Linux and not Windows.

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.

Oracle Migration Workbench DB2 UDB 8.1 Plugins..

I want to migrate db2 udb 8.1 database to oracle 10g ...But iam not able to find the plugins for db2 udb 8.1 in oracle site...... Oracle migration workbench is asking for db2 8.1 plugins can u suggest where i can download ....

From an earlier post on this forum, found by searching for db2:
No plans for DB2 V8 support in the short term. The plugins are hardwired to work against the version they are built against, so it won't work with V7. There are other alternatives out there. One example would be from Ispirer: http://www.ispirer.com/products/ or
from SwisSQL: http://www.swissql.com/oracle-migration.html
[I assume 'so it won't work with V7' in the source post should read 'so the db2 v7 plugin will not work with anything other than db2 v7']

Migrating MS Access queries

Hello,
Can someone point me to a free tool for automatic conversion of Access queries (SELECTs) to Oracle views. Any other advice or help on the issue would also be appreciated.
10x in advance

Hello Herta,
sorry for the delay, but just found your thread.
The MS Access Migration has been dropped from the SQL Developer V4 as the JDK 1.7 does not have the JDBC/ODBC bridge included anymore. The V4 option is only offering the "Copy to Oracle" function which works when you open the MS Access connection, check out the tables present and then do a right click on that table and select "Copy to Oracle".
Another option would be to use the 3.2 SQL Developer release.
