Link two DB2 Databases

Hi,
I have 2 databases running on a AIX ver 5.2 box. The DB2 version is 8.1.4.

My problem is that I want to join the tables from both of these databases in a query. I'm from Oracle background and in oracle its very straight forward to create batabase links.

What is the procedure in DB2. Do I have to use the Federated Systems mechanism or is there simple otherway out.

I have read the thread on a similar article but it talks about DDF which is only available on OS/390.

Please help.

If you look in Chapter 2 of the DB2 Connect User's Guide, it talks about using a Federated Database to run a query between two DB2 databases (or a DB2 and an Oracle database, etc.).

I think what dcaillouet suggested is probably what you will have to do. We have some federated tables, but all are federated on UDB 8 for Win, and alias tables on Z/OS.

Thinking DB2 also has a product called Information Integrator that will let you reference everything but the kitchen sink...

Information Integrator is extremely powerful and is in a sense a dedicated Federated server. It allows for connectivity to a wide range of data sources, and is fast.

It creates the illusion of connecting to a single data source, when in reality your connecting to potentially hundreds of different tables, in different databases, on different platforms.

Once you have the II dB installed, its then just a matter of creating wrappers for your data sources. Then create server mappings, user mappings and nicknames, which are aliases of tables.

And away you go!

Aj.
