What Does the LASR Tables Tab Show?

The LASR Tables tab in SAS Visual Analytics Administrator enables you to view SAS LASR Analytic servers that were created in the SAS metadata, start or stop the LASR Analytic Server connection associated with each server, and manage tables by loading them to the SAS LASR Analytic Server.

Note: If the LASR Tables tab shows the SAS LASR Analytic Server and a server connection, but does not show any libraries, then you must create and assign a library to that server connection in the metadata. This task is performed in SAS Management Console.

You can click Refresh

to have the table display the latest information that is available from the metadata. You can select theShow tables only check box to view the tables in a flat list instead of a hierarchical tree view.

Here is a display of the LASR Tables tab.

LASR Tables Tab

Here is a list that identifies the fields shown in the LASR Tables tab. Note that some of the fields described in this list are not displayed in the display of the LASR Tables tab shown here.

Tables by Server Component

This column displays the SAS LASR Analytic Servers that were registered in metadata. You can expand the tree view for a server component to view the server connection that is associated with that server. One server connection is allowed for each SAS LASR Analytic Server. You can also expand a server connection node to view the libraries and tables that are registered for the server. A server connection represents a SAS LASR Analytic Server instance.

Icons in the LASR Tables Tab	Description
	Represents a SAS LASR Analytic Server component. The SAS Deployment Wizard creates one SAS LASR Analytic Server. You can create multiple SAS LASR Analytic Servers in SAS Management Console. They are displayed as SAS LASR Analytic Server components in the SAS Visual Analytics Administrator.
	SAS LASR Analytic Server connections are created in SAS Management Console. When you expand the node, the server connection that was defined for each server is displayed. Server connections are created in SAS Management Console, and they are started or stopped in SAS Visual Analytics Administrator. When a server connection is started in the LASR Tables tab, it represents the actual running SAS LASR Analytic Server instance.
	Libraries are created in SAS Management Console for the SAS LASR Analytic Server and its associated server connection. Tables are loaded to these libraries in SAS Visual Analytics Administrator. When you expand the tree view for a library in the LASR Tables tab, any tables that are associated with that library are displayed.
	This is the LASR table that was loaded from the metadata. In the LASR Tables tab, you can load tables from the metadata to the SAS LASR Analytic Server. A special configuration is required if you want to load tables for a library that was created by a different administrator. For more information, see SAS Visual Analytics: Administration Guide.

Status

The status column is used to provide a graphical representation of the status for a server connection or a table.

The following icons are used in the Status column:

indicates that the server connection is running and ready for use. If a table is loaded, it also indicates that a table has been loaded to a server connection.
indicates that the server connection is not running. If a table is unloaded, this column also indicates that a table is not loaded to a server connection.
indicates that the server connection did not respond.

Host

This field specifies the host name for the machine that is used as the SAS LASR Analytic Server root node. The host name is specified when the server connection is created in SAS Management Console.

Port

This field shows the network port that is used for communication with the server connection. The port number is specified when the server connection is created in SAS Management Console.

LASR Name

For libraries, this field shows the server tag (for example, hps). For tables, this field shows the table name in the following format:

serverTag:SASTableName

Description

If a description was specified when the SAS LASR Analytic Server component was created in SAS Management Console, that descriptive text is displayed in this column for the server.

If a description was specified when a table was loaded, that descriptive text is displayed in this column. This descriptive text is also displayed next to the LASR table when a user selects data sources in SAS Visual Analytics Designer or SAS Visual Analytics Explorer.

Rows

This field specifies the number of rows in the table. This information is displayed if the table is loaded.

Columns

This field specifies the number of columns in the table. This information is displayed if the table is loaded.

Start/Loaded

For SAS LASR Analytic Server connections, this field shows the time when a server connection was started. For loaded tables, this field shows the time when the table was loaded into the SAS LASR Analytic Server.

Accessed/Modified

For SAS LASR Analytic Server connections, this field shows the last time the server was accessed. For loaded tables, this field shows the time when a LASR table was modified in the SAS LASR Analytic Server.
