Why does my DB2 silent/unattended Install instead invokes DB2 Install wizard and GUI. Can someone help on ths issue?
You will need to use the wizard to install DB2 at least on the primary partition/system of the partitioned database system. See here for the instructions. Thereafter you can use a response file to set up the other partitions. The steps for using a response file mention as a requirement that the primary computer has been set up using the wizard.
