Running the %INDTD_PUBLISH_MODEL Macro

%INDTD_PUBLISH_MODEL Macro Run Process

To run the %INDTD_PUBLISH_MODEL macro, complete the following steps:
  1. Create a scoring model using SAS Enterprise Miner.
  2. Use the SAS Enterprise Miner Score Code Export node to create a score output directory, and populate the directory with the score.sas file, the score.xml file, and (if needed) the format catalog.
  3. Test your connection to Teradata with a local utility such as BTEQ.
  4. Start SAS 9.3 and submit the following commands in the Program Editor or Enhanced Editor:
    %indtdpm;
    %let indconn = server="myserver" user="myuserid" password="xxxx"
        database="mydb";
    
    For more information, see %INDTDPM Macro and the INDCONN Macro Variable.
  5. If you are using the SAS Embedded Process, run the %INDTD_CREATE_MODELTABLE macro.
    For more information, see Creating a Model Table.
  6. Run the %INDTD_PUBLISH_MODEL macro.
    Messages are written to the SAS log that indicate whether the scoring functions or files were successfully created.
    For more information, see %INDTD_PUBLISH_MODEL Macro Syntax.

%INDTDPM Macro

The %INDTDPM macro searches the autocall library for the indtdpm.sas file. The indtdpm.sas file contains all the macro definitions that are used in conjunction with the %INDTD_PUBLISH_MODEL and the %INDTD_CREATE_MODELTABLE macros. The indtdpm.sas file should be in one of the directories listed in the SASAUTOS= system option in your configuration file. If the indtdpm.sas file is not present, the %INDTDPM macro call (%INDTDPM; statement) issues the following message:
macro indtdpm not defined

INDCONN Macro Variable

The INDCONN macro variable is used to provide the credentials to connect to Teradata. You must specify server, user, password, and database to access the machine on which you have installed the Teradata EDW. You must assign the INDCONN macro variable before the %INDTD_PUBLISH_MODEL or the %INDTD_CREATE_MODELTABLE macros are invoked.
Here is the syntax for the value of the INDCONN macro variable:
SERVER="server" USER=user" PASSWORD="password" DATABASE="database";
Arguments
SERVER="server"
specifies the Teradata server name or the IP address of the server host.
USER="user"
specifies the Teradata user name (also called the user ID) that is used to connect to the database.
PASSWORD="password"
specifies the password that is associated with your Teradata user ID.
Tip Use only PASSWORD=, PASS=, or PW= for the password argument. PWD= is not supported and causes an error to occur.
DATABASE="database"
specifies the Teradata database that contains the tables and views that you want to access.
Default Your current database
Requirement You must specify the DATABASE= argument if you use the SAS Embedded Process.
Tip
The INDCONN macro variable is not passed as an argument to the %INDTD_PUBLISH_MODEL macro. This information can be concealed in your SAS job. For example, you can place it in an autoexec file and apply permissions on that file so that others cannot access the user credentials.

%INDTD_PUBLISH_MODEL Macro Syntax

%INDTD_PUBLISH_MODEL
( DIR=input-directory-path, MODELNAME=name
<, MECHANISM=STATIC | EP>
<, MODELTABLE=model-table-name>
<, DATASTEP=score-program-filename>
<, XML=xml-filename>
<, DATABASE=database-name>
<, FMTCAT=format-catalog-filename>
<, ACTION=CREATE | REPLACE | DROP>
<, MODE=PROTECTED | UNPROTECTED>
<, OUTDIR=diagnostic-output-directory>
);
Arguments
DIR=input-directory-path
specifies the directory where the scoring model program, the properties file, and the format catalog are located.
This is the directory that is created by the SAS Enterprise Miner Score Code Export node. This directory contains the score.sas file, the score.xml file, and (if user-defined formats were used) the format catalog.
Restriction You must use a fully qualified pathname.
Interaction If you do not use the default directory that is created by SAS Enterprise Miner, you must specify the DATASTEP=, XML=, and (if needed) FMTCAT= arguments.
See Special Characters in Directory Names
MODELNAME=name
specifies the name that is prepended to each output function to ensure that each scoring function name is unique on the Teradata database. If you are using the SAS Embedded Process, the model name is part of the scoring filenames.
Restriction The scoring function name is a combination of the model and the output variable names. The scoring function name cannot exceed 30 characters. For more information, see Scoring Function Names.
Requirement If you are using scoring functions, the model name must be a valid SAS name that is ten characters or fewer. If you are using the SAS Embedded Process, the model name can be up to 128 characters. For more information about valid SAS names, see the topic on rules for words and names in SAS Language Reference: Concepts.
Interaction Only the EM_ output variables are published as Teradata scoring functions. For more information about the EM_ output variables, see Fixed Variable Names and Scoring Function Names.
MECHANISM=STATIC | EP
specifies whether scoring functions or scoring files are created. MECHANISM= can have one of the following values:
STATIC
specifies that scoring functions are created.
These scoring functions are used in an SQL query to run the scoring model.
See Using Scoring Functions to Run Scoring Models
EP
specifies that scoring files are created.
These scoring files are used by the SAS Embedded Process to run the scoring model. A single entry in the model table is inserted for each new model. The entry contains both the score.sas and score.xml in separate columns. The scoring process includes reading these entries from the table and transferring them to each instance of the SAS Embedded Process for execution.
Requirement If you specify MECHANISM=EP, you must also specify the MODELTABLE= argument.
Note The SAS Embedded Process might require a later release of Teradata than function-based scoring. Please refer to the Scoring Accelerator for Teradata system requirements documentation.
See Using the SAS Embedded Process to Run Scoring Models
Default STATIC
MODELTABLE=model-table-name
specifies the name of the model table where the scoring files are published.
Default sas_model_table
Restriction This argument is available only when using the SAS Embedded Process.
Requirement The name of the model table must be the same as the name specified in the %INDTD_CREATE_MODELTABLE macro. For more information, see the MODELTABLE argument in %INDTD_CREATE_MODELTABLE Macro Syntax.
DATASTEP=score-program-filename
specifies the name of the scoring model program file that was created by using the SAS Enterprise Miner Score Code Export node.
Default score.sas
Restriction Only DATA step programs that are produced by the SAS Enterprise Miner Score Code Export node can be used.
Interaction If you use the default score.sas file that is created by the SAS Enterprise Miner Score Code Export node, you do not need to specify the DATASTEP= argument.
XML=xml-filename
specifies the name of the properties XML file that was created by the SAS Enterprise Miner Score Code Export node.
Default score.xml
Restrictions Only XML files that are produced by the SAS Enterprise Miner Score Code Export node can be used.
The maximum number of output variables is 128.
Interaction If you use the default score.xml file that is created by the SAS Enterprise Miner Score Code Export node, you do not need to specify the XML= argument.
DATABASE=database-name
specifies the name of a Teradata database to which the scoring functions and formats or the scoring files are published.
Default The database specified in the INDCONN macro variable or your current database
Requirement If you are using the SAS Embedded Process, the name of the database must be the same as the database specified in the %INDTD_CREATE_MODELTABLE macro. For more information, see the DATABASE argument in %INDTD_CREATE_MODELTABLE Macro Syntax.
Interaction The database that is specified by the DATABASE argument takes precedence over the database that you specify in the INDCONN macro variable. For more information, see %INDTD_PUBLISH_MODEL Macro Run Process.
Tip You can publish the scoring functions and formats or the scoring files to a shared database where other users can access them.
FMTCAT=format-catalog-filename
specifies the name of the format catalog file that contains all user-defined formats that were created by the FORMAT procedure and that are referenced in the DATA step scoring model program.
Restriction Only format catalog files that are produced by the SAS Enterprise Miner Score Code Export node can be used.
Interactions If you use the default format catalog that is created by the SAS Enterprise Miner Score Code Export node, you do not need to specify the FMTCAT= argument.
If you do not use the default catalog name (FORMATS) or the default library (WORK or LIBRARY) when you create user-defined formats, you must use the FMTSEARCH system option to specify the location of the format catalog. For more information, see PROC FORMAT in the Base SAS Procedures Guide.
ACTION=CREATE | REPLACE | DROP
specifies one of the following actions that the macro performs:
CREATE
creates new functions or files.
REPLACE
overwrites the current functions or files, if functions or files with the same name are already registered.
DROP
causes all functions or files for this model to be dropped from the Teradata database.
Default CREATE
Tip If the function or file has been previously defined and you specify ACTION=CREATE, you receive warning messages from Teradata. If the function or file has been previously defined and you specify ACTION=REPLACE, no warnings are issued.
MODE=PROTECTED | UNPROTECTED
specifies whether the running code is isolated in a separate process in the Teradata database so that a program fault does not cause the database to stop.
Default PROTECTED
Restriction This argument is valid only when using the scoring functions. It has no effect if you specify MECHANISM=EP.
Tip After a function is validated in PROTECTED mode, it can be republished in UNPROTECTED mode. This could result in a significant performance gain.
OUTDIR=diagnostic-output-directory
specifies a directory that contains diagnostic files.
Files that are produced include an event log that contains detailed information about the success or failure of the publishing process and sample SQL code (SampleSQL.txt). For more information about the SampleSQL.txt file, see Scoring Function Names.
Tip This argument is useful when testing your scoring models.
See Special Characters in Directory Names

Modes of Operation

The %INDTD_PUBLISH_MODEL macro has two modes of operation: protected and unprotected. You specify the mode by setting the MODE= argument.
The default mode of operation is protected. Protected mode means that the macro code is isolated in a separate process in the Teradata database, and any error does not cause the database to stop. It is recommended that you run the %INDTD_PUBLISH_MODEL macro in protected mode during acceptance tests. The SAS Embedded Process always operates in its own process, which is equivalent to fenced mode functions. An optimized data transport mechanism allows the SAS Embedded Process to provide fenced mode protection with speed that is as good or better than unfenced functions.
When the %INDTD_PUBLISH_MODEL macro is ready for production, you can run the macro in unprotected mode. Note that you could see a performance advantage when you run in unprotected mode.
