Extenders

Federation Single image of disparate data For Federated Queries between DB2 and Informix;

Only DB2 UDB ( includes Relational Connect) with wrappers

For Federated Queries between DB2 and non IBM databases and access to non-relational sources (XML) and unstructured data; DB2 UDB (includes Relational Connect) DB2 UDB Information Integrator DB2 UDB Integrator for Content

From A to B

db2 => IDS, IIF, XPS Relational Connect*

db2 => Oracle, Sybase, SQL Server (more to come)

Information Integrator*

db2 => zSeries DB2 DB2 Connect

db2 => somewhere else Information Integrator for Content

* Was D.J., now Info Integrator

How does “Federation” Work?

•Federated server

•Client SW for targets 1…N

Don’t move data, “play it as it lays”

•Network client configured and operational

•Authentication

DB2 V8 Relational Connect Configuration GUI

DB2 V8 Relational Connect Configuration GUI

Relational Connect – hints and tipshttp://www-3.ibm.com/software/data/db2/udb/ad/db2irfp7/db2ir101.htm

• Run install: The order has to be V8.1, Relational Connect, then latest fixpack

• IFMX client software• Add Federated Data Sources1. Set the environment variables and update the profile registry. 2. Link DB2 to the Informix client software – djxlinkInformix (pre 8.1)3. Recycle the DB2 instance. 4. Create the Informix sqlhosts file. 5. Set up db2dj.ini6. Create the wrapper. 7. Optional: Set the DB2_DJ_COMM environment variable (double check)8. Create a server. 9. Create a user mapping. 10. Create nicknames for tables, views and Informix synonyms

Relational Connect Syntax

connect to sample;

create wrapper informix;

create server rcxps type informix version 8 wrapper informix

options ( node 'mkxps' , dbname 'stores_demo', cpu_ratio '.1' io_ratio '.1' );

create user mapping for db2inst1 server rcxps

options ( remote_authid 'informix', remote_password ‘techconf' );

create nickname rcx_customer for rcxps."informix"."customer";

select * from rcx_customer;
