well I dunno about the specific driver you are using, but the message you are posting actually is like that:
the driver can connect you and provide information like database version and stuff. Or don't connect and just register with the connection details you provide (port, hostname etc) and you test the connection later.
From a client execute the following DB2 commands
db2 catalog tcpip node TCPN remote SRVR server 60001 remote_instance DB2INST1 system SRVR ostype AIX
db2 catalog database DTBS as ALIAS at node TCPN authentication server
db2 catalog system odbc data source DTBS
TCPN tcp nodename; can be anything; I usually make it same as DTBS.
SRVR is the database server name(DNS); 60001 should be replaced by the port number in the /etc/services file on a unix system;(like the default 1521 on Oracle)I think the IBM default is 3700.
DB2INST1 is the instance name on the server.Replace AIX with your OperatingSystem.
DTBS is the database name. ALIAS is its alias; can be the same as DTBS.These commands catalog the database and produce a system DSN called DTBS.
