If you're installing Domino (or anything for that matter) on a System i, then you should make sure that your joblog is generated when you signoff. Simply prompt the SIGNOFF command and use *LIST for the joblog option. I think just SIGNOFF *LIST will work. Doing this will make sure that you have a record of all the commands processed during your job. For instance, installing Domino does a lot of background stuff with the RSTLICPGM command you have to use. If anything goofy happens you'll want a copy of the joblog to send to support.
Thanks to César for a quick clarification to this tip:
I prefer the DSPJOBLOG OUTPUT(*PRINT), perhaps because I’m a developer or because I still use the same session for more things.Regardless, make sure you get a joblog of the install/uninstall... :)
What I do not suggest is generate a joblog with the SIGNOFF *LIST when you’re removing Domino from your system, due to some functionality of the system I’ve seen “weird” things appear on the joblogs (you know, *MSGF is deleted and joblog is generated/built afterwards).
