When installation is initially performed, the resulting installation is owned by a single user or group. You can change file ownership and permissions after installation using the chutils command.
Installation Manager reports an error when the user does not have appropriate system permissions.
You can use the chutils command to set the file ownership and permissions for an entire installation to an owner or group that differs from the user that performed the initial installation. The main benefit is the ability to have the initial installation performed by one user and then have different users perform supported operations such as feature installations, edition upgrades, maintenance installations (such as fix packs or refresh packs), and feature-pack installations.
