| Moving and Accessing SAS Files across Operating Environments |
CEDA does not
replace the traditional file
transport methods (PROC CPORT and PROC CIMPORT or the XPORT engine with PROC
COPY or the DATA step), PROC UPLOAD and
PROC DOWNLOAD in SAS/CONNECT, or server
processing in SAS/SHARE because of
these limitations:
- CEDA features are implemented for Version 8 SAS
data sets, PROC SQL views, and MDDBs (for read-only access). CEDA does not
support Version 8 stored programs, catalogs, DMDBs, or FDBs, nor does it support
any pre-Version 7 member types.
- CEDA does not support update access.
- CEDA does not support subsetting by means of an
index.
- CEDA is available for hosts that use directory-based
file structures. On OS/390, CEDA is available only for SAS data sets that
reside in a UNIX System Services Directory. Bound libraries that are traditionally
used on the OS/390 host do not implement CEDA.
If your application can operate within these limitations,
then CEDA offers the simplest strategy for file access across a network. If
your needs exceed these limitations, then you still have other methods available.
