Required Arguments
When SAS is assigning a SAS library that the SAS job has already
allocated as DISP=SHR, the DLDISPCHG option controls whether SAS re-allocates
a library as DISP=OLD.
- DLDISPCHG=AUTO
-
SAS determines whether
to upgrade an existing DISP=SHR allocation based on all available
information. This information includes the level of authorization
with which the client user ID (if applicable) and the SAS session
itself have to access the library. AUTO is recommended for SAS/SHARE
servers.
- DLDISPCHG=BYREQUEST
-
SAS upgrades an existing
DISP=SHR allocation only if it is explicitly requested by DISP=OLD
on the library assignment. BYREQUEST is recommended for single user
SAS sessions.
- DLDISPCHG=COMPAT91
-
SAS applies the same
rules as specified in SAS Release 9.1.3 when upgrading an existing
DISP=SHR allocation. COMPAT91 is the default.
- DLDISPCHG=NONE
-
SAS does not upgrade
an existing DISP=SHR allocation under any circumstances.
