This section
describes how to install and configure the in-database deployment
package for Teradata (SAS Formats Library for Teradata and SAS Embedded
Process). The in-database deployment packages for Teradata must be
installed and configured before you can perform the following tasks:
-
Use the %INDTD_PUBLISH_FORMATS format publishing macro to publish the SAS_PUT( )
function and to publish user-defined formats as format functions inside
the database.
-
Use
the %INDTD_PUBLISH_MODEL
scoring publishing macro to publish scoring model files or functions
inside the database.
-
Use the SAS In-Database Code Accelerator
for Teradata to execute DS2 thread programs in parallel inside the
database.
For more information,
see the SAS DS2 Language Reference.
-
Perform data quality operations
in Teradata using the SAS Data Quality Accelerator for Teradata.
For more information,
see SAS Data Quality Accelerator for Teradata: User’s Guide.
Note: If you are installing the
SAS Data Quality Accelerator for Teradata, you must perform additional
steps after you install the SAS Embedded Process.
For more information,
see SAS Data Quality Accelerator for Teradata.
-
Run SAS High-Performance
Analytics when the analytics cluster is using a parallel connection
with a remote Teradata data appliance. The SAS Embedded Process, which
resides on the data appliance, is used to provide high-speed parallel
data transfer between the data appliance and the analytics environment
where it is processed.
For more information,
see the SAS High-Performance Analytics Infrastructure:
Installation and Configuration Guide.
The in-database deployment
package for Teradata includes the SAS formats library and the SAS
Embedded Process. In the fourth maintenance release
of SAS 9.4 (November 2016), if you license SAS
In-Database Technologies for Teradata, the SAS Data Quality Accelerator
for Teradata scripts are also deployed with the SAS Embedded Process.
The SAS formats library
is a run-time library that you install on your Teradata system. This
installation is done so that the SAS scoring model functions or the
SAS_PUT( ) function can access the routines within the run-time
library. The SAS formats library contains the formats that are supplied
by SAS.
Note: The SAS formats library is
not required by the SAS Data Quality Accelerator for Teradata.
The SAS Embedded
Process is a SAS server process that runs within Teradata to read
and write data. The SAS Embedded Process contains macros, run-time
libraries, and other software that is installed on your Teradata system.
Note: If you are performing a system
expansion where additional nodes are being added, the version of the
SAS formats library and the SAS Embedded Process on the new database
nodes must be the same as the version that is being used on already
existing nodes.
Note: In
addition to the in-database deployment package for Teradata, a set
of SAS Embedded Process functions must be installed in the Teradata
database. The SAS Embedded Process functions package is downloadable
from Teradata.
