    • 3. Agenda You are here …
    • 4. 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
    • 5. DB2 Federation Other Servers Informix Oracle Sybase Microsoft Teradata DB2 WEB Data Sources OLE/OLE DB data sources Lotus Notes MS Exchange MS Excel MS Access, ... DB2 Client DB2 Connect Native Interface Data Links Third-party Gateway TABLE UDFs to Universal Data AST cache of external data (reliability/perf)

    • 7. 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
    • 8. From A to B * Was D.J., now Info Integrator Information Integrator for Content somewhere else db2 => DB2 Connect zSeries DB2 db2 => Information Integrator* Oracle, Sybase, SQL Server (more to come) db2 => Relational Connect* IDS, IIF, XPS db2 =>
    • 9. How does “Federation” Work? You are here … Target 1 Target N
      • Federated server
      • Client SW for targets 1…N
      • Don’t move data, “play it as it lays”
      • Network client configured and operational
      • Authentication
    • 10. From db2 => to Informix with DB2 Relational Connect You are here … XPS IDS
      • DB2 v8.1( includes Relational Connect)
      • DB2 Informix Client SDK
      • TCP Network listener configured and operational
      • Authentication
    • 11. DB2 V8 Relational Connect Configuration GUI
    • 12. DB2 V8 Relational Connect Configuration GUI
    • 13. Relational Connect – hints and tips http://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 Sources
      • 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
    • 14. 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;
