Chapter 5 Dictionary Security
Overview
System Dictionary includes a security scheme to limit access to
authorized users, and to control the level of access of each user.
Generally, this scheme consists of the following requirements:
1. You must use the correct scope and its associated password to have
the necessary access rights to the dictionary.
2. To have unlimited access to a definition or occurrence, the
current scope must be either its owner scope or the Dictionary
Administrator scope. A scope that does not own a particular
occurrence may have explicit access to it by being associated with
that occurrence.
3. The entities and relationships in the dictionary must have the
correct sensitivity to allow access by a scope that is not its
owner scope, the Dictionary Administrator scope, or a scope that
is associated with the occurrence.
System Dictionary checks for the necessary dictionary open mode and scope
rights it needs to succeed, and if attempting to access an occurrence,
also checks the association and sensitivity of that occurrence. If any
of the following occur, the operation fails and an appropriate error code
is returned.
* The dictionary is not open in the proper mode.
* The current scope does not have sufficient scope rights.
* The scope attempting to access an occurrence does not have the
necessary association with that occurrence.
* The sensitivity of the occurrence restricts access.
This chapter contains references to all System Dictionary security
operations, and to a number of operations whose performance and output
depend greatly on the particular security scheme installed at the time
you call them. To completely understand all of the information in this
chapter, it may be necessary to refer to the detailed explanations of
either the System Dictionary intrinsics, which are located in Chapter 4
of the HP System Dictionary/XL Intrinsics Reference Manual (32256-90002),
or the descriptions of the SDMAIN commands, which are located in Chapter
4 of the HP System Dictionary/XL SDMAIN Reference Manual (32256-90001).
