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—Distributed Relational Database Architecture—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.
NOTEDB2 Connect software is only required when communicating from a workstation to a host; it is not required in the other direction (from a host to a workstation). |
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.
