In Upgrades or Support Packages updates using the Software Update Manager (SUM) tool, several system parameters are defined during PREPARE.

Quite often there is a need to change one or more parameters, due to errors, poor performance or miss configured options.

Most common errors derived from incorrect parameters are:

*DDIC/DB password (including shadow instance)
*DVD mount paths
