In addition to parallel processing capabilities, SPD Server also provides security features including userid/password validation and ACL file security. It also provides backup and recovery facilities.
In order to use SPD Server you must invoke two sessions on the server machine: one to run a name server and one to run the actual data server. When a client connects to SPD Server through the use of a libname statement, a proxy SAS session (spdsbase) is automatically started to process all client requests. SPD Server 4 supports server sessions on HP-UX, Solaris, AIX, Compaq's Digital Unix, and Windows NT. The client applications can execute in sessions on the same or different machines. The client applications connect to the server using syntax on the libname statement. Therefore, once the server environment has been initiated, code modifications are limited to the libname statement(s) in the client application.
SPD Server was initially released in conjunction with Release 6.12 of the SAS System. SPD Server provides a high performance data store of very large SAS data sets. Therefore, it is particularly suited as part of a data warehousing solution where the SAS system is being used to construct, manage and analyze enterprise-wide datamarts.
