Moving and Accessing SAS Files across Operating Environments

Accessing Remote SAS Files by Using a SAS/SHARE Server

An alternative to accessing remote SAS files (including Version 8 CEDA files) through the network, the SAS/SHARE server provides concurrent multi-user read, write, and update access to common data that is located on a remote host. The SAS/SHARE locking facility enables the SAS/SHARE server to manage complex requests for I/O service. For complete details about SAS/SHARE, see SAS/SHARE User's Guide.

A fundamental feature of SAS/SHARE is its ability to manage requests for access to common data among multiple hosts that may or may not be compatible with the other. For incompatible hosts that request access to common data, SAS/SHARE performs a dynamic translation of the incompatible data between the native formats of the hosts for each read, write, or update operation.

Unlike the traditional transport methods that create an explicit transport file, SAS/SHARE dynamically translates only the incompatible data per transaction. This dynamic translation bypasses the explicit creation of a transport file. For example, if a Version 6 Macintosh client reads data on a server that is on an HP-UX host, only the character data needs translation. The Macintosh and the HP-UX hosts represent numeric data in the same way; however, they represent character data differently. For lists of compatible hosts, see Architectural Compatibility.

Note: For the MDDB member type, the SAS/MDDB server rather than the SAS/SHARE server dynamically translates the data upon access. [cautionend]
