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 or other grid middleware 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.
