Publishing Scoring Model Files in Aster nCluster

The integration of the SAS Embedded Process and Aster nCluster allows scoring code to be running directly using the SAS Embedded Process on Aster nCluster through a SQL/MR function.
The SQL/MR function is the framework for enabling execution of user-defined functions within Aster nCluster through an SQL interface. A SAS SQL/MR function, SAS_SCORE(), performs the scoring of models published in Aster nCluster.
The %INDAC_PUBLISH_MODEL macro uses some of the files that are created by the SAS Enterprise Miner Score Code Export node: the scoring model program (score.sas file), the properties file (score.xml file), and (if the training data includes SAS user-defined formats) a format catalog.
The %INDAC_PUBLISH_MODEL macro performs the following tasks:
  • takes the score.sas and score.xml files that are created using the Score Code Export node and produces two files for each scoring model. The following files are produced:
    • sasscore_modelname.ds2 . This file contains code that is executed by the SAS_SCORE() function
    • sasscore_modelname_io.xml. This file contains the scoring model's input and output variables
  • takes the format catalog, if available, and produces the sasscore_modelname_ufmt.xml file. This file contains user-defined formats for the scoring model that is being published.
  • uses the SAS/ACCESS Interface to Aster nCluster to insert the three scoring files into the NC_INSTALLED_FILES table.
After the scoring files are published, you can call the SAS_SCORE() function to execute the scoring model. For more information, see SAS_SCORE() Function.
