Working with User Accounts
The user account that boots the domain must be the same user who configures the domain. This is a Tuxedo requirement, not a PeopleTools requirement. This means that the user account under which the domain processes will run must have read-write access to the domain directory.
The owner of the domain processes is the user account who starts the domain. This is different from Microsoft Windows, where the domain processes are booted by the account that starts the Oracle ProcMGR service. If you use both Windows and UNIX servers to deploy PeopleSoft, keep this subtle distinction in mind between the two operating systems.
