-
RSASUSER
-
limits access to the Sasuser data library
to read-only access in environments where all users share the Sasuser library.
-
NORSASUSER
-
enables a user to open a file in the Sasuser
library for update access, thus preventing users from sharing members of the
Sasuser data library. Update access to the Sasuser library requires exclusive
rights to the data library member. NORSASUSER is the default value.
Specifying RSASUSER enables a group of
users to share Sasuser data library members by enabling all users to have
read-only access to members. For example, if RSASUSER is in effect, each
user can open the Sasuser.Profile catalog for read-only access, enabling other
users to concurrently read from the Profile catalog.
However, no user can write information out to the Profile catalog;
you receive an error message if you try to do so.
Specifying RSASUSER in a SAS session affects only that
session's access to files. To enable a group of users to share members in
the Sasuser data library, the system administrator should set RSASUSER in
the network version of the SAS configuration file, which is shared by all
users who share the Sasuser data library.
If you specify RSASUSER but no Profile catalog exists
in the Sasuser data library, the Profile catalog
is created in the Work data library.
Whether the RSASUSER system option is useful depends
on how SAS is being used. While the RSASUSER system
option is extremely useful when users must share information (such as the Profile catalog)
stored in the Sasuser data library,
it is not useful if these same users are using SAS/ASSIST software. SAS/ASSIST software
requires update access to the Sasuser data library.
