RSASUSER

Default:	NORSASUSER
Valid in:	configuration file, SAS invocation
Windows specifics:	Network considerations

RSASUSER

limits access to the SASUSER data library to read-only access. If you are running the SAS System under Windows on a network, it is common to have a SASUSER data library that is shared by a group of users. By default, if one user has a member of the SASUSER data library open for update, all other users are denied access to that SAS data library member. For example, if one user is writing to the SASUSER.PROFILE catalog, no other user can even read data from the PROFILE catalog.

Specifying RSASUSER enables a group of users to share SASUSER data library members by allowing all users read-only access to members. In the PROFILE catalog example, if RSASUSER is in effect, each user can open the PROFILE catalog for read-only access, allowing 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 manager 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.

NORSASUSER

prevents users from sharing members of the SASUSER data library because it allows a user to open a file in the SASUSER library for update access. Update access requires exclusive rights to the data library member. NORSASUSER is the default value.

Details

Whether the RSASUSER system option is useful depends on how the SAS System 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.
