Glossary
- application server
-
a server that is used for storing applications.
Users can access and use these server applications instead of loading
the applications on their client machines. The application that the
client runs is stored on the client. Requests are sent to the server
for processing, and the results are returned to the client. In this
way, little information is processed by the client, and nearly everything
is done by the server.
- authentication
-
the process of verifying the identity of a person
or process within the guidelines of a specific authorization policy.
- authentication domain
-
a SAS internal category that pairs logins with
the servers for which they are valid. For example, an Oracle server
and the SAS copies of Oracle credentials might all be classified as
belonging to an OracleAuth authentication domain.
- grid
-
a collection of networked computers that are coordinated
to provide load balancing of multiple SAS jobs, scheduling of SAS
workflows, and accelerated processing of parallel jobs.
- grid computing
-
a type of computing in which large computing tasks
are distributed among multiple computers on a network.
- grid control server
-
the machine on a grid that distributes SAS programs
or jobs to the grid nodes. The grid control server can also execute
programs or jobs that are sent to the grid.
- grid monitoring server
-
a metadata object that stores the information
necessary for the Grid Manager plug-in in SAS Management Console to
connect with the Platform Suite for SAS to allow monitoring and management
of the grid.
- grid node
-
a machine that is capable of receiving and executing
work that is distributed to a grid.
- identity
-
See metadata identity.
- job
-
a metadata object that specifies processes that
create output.
- load balancing
-
for IOM bridge connections, a program that runs
in the object spawner and that uses an algorithm to distribute work
across object server processes on the same or separate machines in
a cluster.
- logical grid server
-
a metadata object that stores the command that
is used by a grid-enabled SAS program to start a SAS session on a
grid.
- logical server
-
in the SAS Metadata Server, the second-level object
in the metadata for SAS servers. A logical server specifies one or
more of a particular type of server component, such as one or more
SAS Workspace Servers.
- login
-
a SAS copy of information about an external account.
Each login includes a user ID and belongs to one SAS user or group.
Most logins do not include a password.
- metadata identity
-
a metadata object that represents an individual
user or a group of users in a SAS metadata environment. Each individual
and group that accesses secured resources on a SAS Metadata Server
should have a unique metadata identity within that server.
- metadata repository
-
a collection of related metadata objects, such
as the metadata for a set of tables and columns that are maintained
by an application. A SAS Metadata Repository is an example.
- metadata server
-
a server that provides metadata management services
to one or more client applications. A SAS Metadata Server is an example.
- plug-in
-
a file that modifies, enhances, or extends the
capabilities of an application program. The application program must
be designed to accept plug-ins, and the plug-ins must meet design
criteria specified by the developers of the application program. In
SAS Management Console, a plug-in is a JAR file that is installed
in the SAS Management Console directory to provide a specific administrative
function. The plug-ins enable users to customize SAS Management Console
to include only the functions that are needed.
- SAS Management Console
-
a Java application that provides a single user
interface for performing SAS administrative tasks.
- SAS Metadata Repository
-
one or more files that store metadata about application
elements. Users connect to a SAS Metadata Server and use the SAS Open
Metadata Interface to read metadata from or write metadata to one
or more SAS Metadata Repositories. The metadata types in a SAS Metadata
Repository are defined by the SAS Metadata Model.
- SAS Metadata Server
-
a multi-user server that enables users to read
metadata from or write metadata to one or more SAS Metadata Repositories.
The SAS Metadata Server uses the Integrated Object Model (IOM), which
is provided with SAS Integration Technologies, to communicate with
clients and with other servers.
- SAS Workspace Server
-
a SAS IOM server that is launched in order to
fulfill client requests for IOM workspaces. See also IOM server and
workspace.
