you can see the oracle different user's permission.
is it OK it is cchanged to tusted mode system's umask into another umask-o22,027?


I check

[RAC_1]

umask setting has nothing to do with ipcs and oracle ipcs. umask controls the perms of the files/dirs -of new files being created.

man umask for details.

Also umask setting has nothing to do with the fact that "if system is in trusted mode or not"

[Christine Hartman]

you can setup umask settings in the /etc/profile
you can also setup root's umask in it's own .profile (either in / or in /root)

If oracle needs it's own special umask setting to do stuff...it can modify it's own .profile and set it's own umask setting.
