Configuring communications manually © Copyright IBM Corp. 1993-2002 1 2 Connectivity Supplement Chapter 1. Configuring TCP/IP communications manually Configuring TCP/IP communications manually between DB2 Connect and a host and iSeries database server You can manually configure your TCP/IP connection between a DB2 Connect server and a host or iSeries database. TCP/IP is normally configured automatically using the Configuration Assistant (CA). Prerequisites: Before you manually configure a TCP/IP connection between DB2 Connect and a host or iSeries database server, ensure that: v TCP/IP is functional on the DB2 Connect server and host or iSeries system. v You have identified the following parameter values, using
