Add a LASR Library :: SAS® Visual Analytics 7.4: Administration Guide

Introduction

Here are the main reasons for creating a new LASR library:

You want additional separation for management or ease-of-use purposes.
You added a new directory within co-located HDFS or NFS-mounted MapR. You already created the new SASHDAT library. Now, you need to create the corresponding LASR library.

Tip

The following instructions use SAS Management Console. To instead use SAS Environment Manager, see Register a SAS LASR Analytic Server Library Using SAS Environment Manager in the SAS Intelligence Platform: Data Administration Guide.

On the Plug-ins tab in SAS Management Console, expand Data Library Manager. Right-click Libraries, and select New Library.
In the New Library wizard, select High-Performance AnalyticsSAS LASR Analytic Server Library. Click Next.
Enter a name (for example, Sales LASR). If necessary, adjust the location. Click Next.
(Optional) Assign the library to one or more SAS Application Servers. Click Next.

Note: Assigning a LASR library to a SAS Application Server facilitates interactions from clients such as SAS Enterprise Guide. Assignments can also affect which SAS Application Server is used for interactions with this LASR library and its associated SAS LASR Analytic Server. See Which Server is Used?.

Set library properties as follows. Click Next.

Libref	Enter an identifier of your choice (for example, `SALESLIB`).
Engine	This field is not editable. The value (`SASIOLA`) is the engine name for LASR libraries.
Server tag	See Server Tags.
Data provider library	If you want participating tables to be reloaded each time the associated server starts, specify a Base SAS library to function as the backing store for this LASR library. See Reload-on-Start.

Assign the library to a SAS LASR Analytic Server by entering settings as follows. Click Next.

Database Server	Select a server from the drop-down list.
Connection	Use the pre-selected value (which prepends the selected server name with the string `Connection:`).
Default Login	This field is not editable. The value is `None`.

If you want to adjust the default grants of the Administer permission that the wizard applies to the library, move identities from one list to the other. Click Next.

Note: Only users who have the Administer permission for the library can load new tables to memory. The library inherits settings from its parent folder, so it might not be essential to add any explicit grants.
Click Finish.

If you want the associated server to start on demand for data load and import requests against the new library, enable autostart for the library. See Autostart a SAS LASR Analytic Server.
If you want locally imported files to reload each time the associated server restarts, enable reload-on-start for the library. See Reload-on-Start.
If you want to automatically synchronize the library’s in-memory data against source tables in a host directory, set up a corresponding implementation of autoload. See Autoload.
If the library is associated with a distributed server and provides high-volume access to small tables, consider setting an extended attribute that optimizes performance. See VA.TableFullCopies.
