1.6 Host Connectivity

DB2 Connect is the software product containing the licensed files required to communicate from a DB2 distributed client, also known as the DRDA Application Requester, to a host DB2 server, a DRDA Application Server. (DRDA&8212;Distributed Relational Database Architecture&8212;is the standard that defines formats and protocols for providing transparent access to remote data.) Host DB2 servers include DB2 UDB for z/OS and OS/390, DB2 UDB for VM/VSE, and DB2 UDB for iSeries. DB2 Connect also includes a DB2 runtime client.

As indicated earlier, if you install DB2 UDB ESE there is no need to install DB2 Connect since DB2 UDB ESE comes with a DB2 Connect component.

DB2 Connect comes in two main flavors.

  • The Personal Edition supports the direct connection of one DB2 client to multiple host DB2 servers.
  • The Enterprise Edition supports the connection of multiple DB2 clients to multiple host DB2 servers via a DB2 Connect server.
