What Does the In-Memory Data Tab Show?

The In-Memory Data tab is the part of the data preparation interface that is used for starting and stopping SAS LASR Analytic Server instances. It is also used for loading and unloading tables to those server instances.

The following display shows an example of the In-Memory Data tab.

Data Preparation In-Memory Data Tab

Note: If the In-Memory Data tab does not show any server instances and reports an error, then contact your system administrator to make sure the SAS LASR Analytic Server Monitor is running.

You can click Refresh

to have the table display the latest information that is available from the SAS LASR Analytic Server Monitor. You can select the Show tables only check box to reorganize the table by table name rather than user ID and server instance.

The following list identifies the fields shown in the table:

Tables by Owner

This column lists the unique user IDs that have started server instances. You can expand the node to view the individual server instances started by the user ID and the tables that are loaded into memory on the server instance.

Status

The status column is used to provide a graphical representation of the status for a server instance.

The following icons are used in the status column:

indicates that the server instance is running and ready for use.
indicates that the server instance is stopped. These servers were not stopped manually, but ran until they reach the maximum run time. These items are grouped under the orphan user ID to represent that the server instance is not running. For more information, see Orphan Server Description Files.
indicates that the server instance did not respond to network communication for 20 seconds.

Server Description File

For servers that are in a ready state, this field shows the server description file name. For servers that are listed under the orphan user ID, this field lists the fully qualified path to the server description file.

Host

This field specifies the host name for the machine that is used as the SAS LASR Analytic Server root node.

Port

This field specifies the network port that is used for communication with the server instance.

Description

This field specifies the table description. This description is visible in the explorer interface when users select a table to explore. Some tables do not have a description because either a description was not stored with the data set, or the data source does not support associating a description with a table.

Rows

This field specifies the number of rows in the table.

Columns

This field specifies the number of columns in the table.

Start Time

For server instances, this field specifies the date and time that the server instance was started. For tables, this field specifies the date and time that the table was loaded into memory.

Last Access

This field specifies the date and time that the server instance was accessed.
