Setting file permissions

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.

[Windows] Restriction: The set-permissions feature is not currently available on Windows® operating systems.

Verifying file permissions

Installation Manager reports an error when the user does not have appropriate system permissions.

Setting file ownership and permissions with the chutils command

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.

The command can be used for the following:
  • Add or remove the ability of other non-root users to update the installation
  • Transfer all file ownership of the installation to another user
  • Reestablish consistent file permissions for the entire installation
The command can edit the following ownership and permissions:
  • File owner
  • File group
  • Owner permissions

    You can only change owner permissions to the default values set during installation using the -setmod reset parameter.

  • Group permissions

    You can elevate group permissions to match the owner permissions using the -setmod grp2owner parameter.

    Limitation: Do not use chutils -setmod=grp2owner to set permissions if you want to update the product with a fix pack using group mode. In this case, use chutils -setowner=user_name.
  • Others permissions

    You can only change others, or "world," permissions to the default values set during installation through the -setmod parameter.

For more information on using the chutils command, read chutils command.
