The Question is:
what should i do, if i would like to define a default permission of directory
The Answer is :
If the OpenVMS Wizard understands the question correctly, please
skim through the OpenVMS security manual for information on the
following OpenVMS security features:
o default protection ACE documentation
This permits the establishment of a default protection mask for
files created in the directory.
o the options=default setting within identifier ACEs
Permits adding ACEs to files automatically, based on the settings
on the parent directory
o the resource identifier and associated identifier ACE.
Permits establishing shared areas, both for file ownerships and
for disk quotas and such. Useful for directories associated with
development projects or shared databases, and for setting up shared
scratch storage areas.
o the subsystem identifier mechanism.
These identifiers can be assigned to executable images, and can
be used to control access to associated resources and objects
(queues, data files, global sections, etc).
All of the above features are documented in detail in the security
For individual users, the SET SECURITY/DEFAULT command and the system
parameter RMS_FILEPROT can be of interest -- these set the protection
mask used by the process by default. (This process default protection
mask may or may not be relevent to the particular question you intended
Some (or all) of these (typically ACL-based mechanisms) should address
(at least one interpretation of) the question.
