Name Server Commands
The SPD Server LIBNAME engine connects to the Name Server. The Name Server
resolves LIBNAME domain names into physical file system paths for librefs. The Name
Server also resolves host node and end-point (TCP port) addresses for each LIBNAME.
Each SPD Server host process (
spdsserv process) registers LIBNAME domain information
from its configuration file with its appointed Name Server process ( spdsnsrv process).
Multiple SPD Server hosts can use the same Name Server to register their LIBNAME
domains. The only requirement is that the combination of the LIBNAME= option values
from the SPD Server host's LIBNAME configuration file must be unique across all SPD
Server hosts connecting to the Name Server.
The SPD Server Name Server is invoked using the following command line syntax:
spdsnsrv [-option [optval]...]
The spdsnsrv command supports the following options:
-listenport port#
Used to specify the explicit TCP port number that the Name Server uses to accept
connections from the SPD Server LIBNAME engine and its SPD Server hosts. If no
port is specified, the Name Server queries the system for port addresses using the service
name "spdsname". If no such service has been registered, the system chooses a dynamic
port number for the Name Server to use.
-licensefile lic-file
License file keys are generated by SAS Institute and supplied to you. With this
production release of SPD Server, you receive an SPD Server license key for each
machine where you license the SPD server and that key must be entered into this license
file by the SPD Server administrator. The SPD Server will not run on a given machine
without first entering a valid license key in this file. License keys are plain text strings
that product, site, and machine information along with the password required to allow
you to use the SPD Server in this specific environment.
SPD Server Host Commands
The SPD Server LIBNAME engine connects to the SPD Server host to access data in the
server environment. The SPD Server host uses the SPD Server password file to validate
each SPD Server user, and then creates a LIBNAME proxy process on behalf of each of
them.
The SPD Server host is invoked using the following command line syntax:
spdsserv [-option [optval]...]
Part of the function of the SPD Server host process is to startup SPD Server logging
processes. The spdslog process performs message logging functions. The spdsaud process
performs audit logging functions. Message and audit logging functions are controlled using
spdsserv command line options.
Both message and audit logging facilities include automatic logfile naming and periodic
logfile cycling support.
Spdsserv command line options control automatic logfile naming
and cycling properties. Server availability improves because you can periodically switch
to a new server log and/or audit log file without halting and restarting the SPD Server
environment.
Audit log records are kept for all resource accesses by each LIBNAME proxy process. The
audit log saves records in its own separate space, away from other server log files. A sample
