1904239 - SUM options to change parameters entered in INITPUT and INITSUBST phases


In Upgrades, Enhancement Packages or Support Pacakges 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 misconfigured options.

Most common errors derived from incorrect parameters are:

  • DDIC/DB password (including shadow instance)
  • DVD mount paths
  • Number of parallel processes
  • SPDD/SPAU request
  • <sid>adm password


This article shows options to rectify such parameters during the procedure.
