Decide which OS user account will be assigned the instance administrator role. You can assign it to a new user or to an existing one, but you cannot assign it to the OS superuser (root).
The following example shows an OS user account with the name "fsepuser" being assigned the instance administrator role.
# useradd fsepuser # passwd fsepuser
Note
The following note applies if using WebAdmin for operations:
If the password is changed for the user account of the instance administrator, set the changed password using ALTER ROLE WITH ENCRYPTED PASSWORD.
