IBM i QNOTES user profile requirements

Domino® for IBM® i requires *RWX (read, write and execute) access to the root integrated file system directory.

For example, when creating new Domino servers, a new directory needs to be created at the root directory for the associated new Domino data directory. By default, IBM i sets the public access to the root integrated file system directory to *RWX. However, for security reasons, you may decide to restrict public access. For example, public access may be set to *X (execute). In this case, the QNOTES user profile should be given *RWX access to the root integrated file system directory.
