hi all

First time question.

Can anyone please post any links to

Guidelines / Instructions / Procedures for migrating a DB2 database (tables, functions, indexes, procedures, etc) to Oracle.

I'll keep searching this site but so far haven't found anything.

Any help or pointers appreciated Smile

hai,
try out using oracle heterogenous services,it was an excellent on e which makes any non-oracle database to be queried from oracle itself.

a seperate tnsnames and listener and parameter file have to be maintained for this. with no 3rd party tool u can come out successfuly.

one greatest disadvantage is that the long datatype,clob,blob will not be supported in this,

if u have any problem call me in my ramsat_077@yahoo.com
bye!

Currently there is no plugin for UDB DB2 v8. There is an enhancement request (#4744020) logged to get this plugin.
All customers requiring a V8 UDB plugin for OMWB should get in touch with Oracle Support and ask the support analyst to be subscribed to this enhancement request.
Depending on the demands of this Plugin OMWB development will then decide to provide a plugin for UDB V8.

This note outlines the options for migrating this database without using OMWB.

The options to do a migration without using OMWB are -

- use a gateway - such as TG4DRDA or generic connectivity - to do a 'create Oracle_table as select
from DB2_table' for each table. You would then have to manually create all the other objects,
permissions etc that existed in the DB2 database.

- load the DB2 data into flat files and use SQL*Loader to put into Oracle tables. Again manual
work is required for the other objects.

- contact the Oracle Product Technology Services (PTS) group for assistance. See the webpage -

http://www.oracle.com/technology/tech/migration/isv/mig_services.html

- use a third party migration tool. See -

http://www.oracle.com/technology/tech/migration/isv/third_party.html

These companies may also be able to help specifically with DB2 V8 -
