Better late than never, I have posted here a spreadsheet for installation of Sametime 9, similar to my IBM Connections 4.5 installation spreadsheet.
I took this IBM Sametime Wiki page provided and broke it down by topics (WAS, DB2, MUX, Media Manager, etc).
For those that need, that is, should be, documenting your installation details, hopefully this helps make your life easier.
You can download my spreadsheet from the link below:
