IBM Information Integration Infrastructure
 II Infrastructure enables integration of diverse, distributed and real
time data as if it were a single source, no matter where it all
resides. Key features of the infrastructure include ability to;





Federate,
Search,
Cache,
Transform,
And replicate desperate data

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?
You are here …
Target 1
•Network client configured
and operational
•Federated server
•Client SW for
targets 1…N
Don’t move data,
“play it as it lays”
•Authentication
Target N
From db2 => to Informix with DB2 Relational Connect
You are here …
XPS
•TCP Network listener
configured and operational
•Authentication
•DB2 v8.1( includes
Relational Connect)
•DB2 Informix Client
SDK
IDS
DB2 V8 Relational Connect Configuration GUI

Set the environment variables and update the profile registry.
Link DB2 to the Informix client software – djxlinkInformix (pre 8.1)
Recycle the DB2 instance.
Create the Informix sqlhosts file.
Set up db2dj.ini
Create the wrapper.
Optional: Set the DB2_DJ_COMM environment variable (double check)
Create a server.
Create a user mapping.
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;
