Running the %INDTD_PUBLISH_MODEL Macro

%INDTD_PUBLISH_MODEL Macro Run Process

To run the %INDTD_PUBLISH_MODEL macro, complete the following steps:

Create a scoring model using SAS Enterprise Miner.
Use the SAS Enterprise Miner Score Code Export node to create a score output directory. Populate the directory with the score.sas file, the score.xml file, and (if needed) the format catalog.
Test your connection to Teradata with a local utility such as BTEQ.
Start SAS and submit the following command in the Program Editor or Enhanced Editor:
```
%let indconn = server=myserver user=myuserid password=xxxx database=mydb;
```
For more information, see the INDCONN Macro Variable.
If you use the SAS Embedded Process, run the %INDTD_CREATE_MODELTABLE macro.

For more information, see Creating a Model Table.
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.

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 use the SAS Embedded Process, the model name is part of the scoring filenames.

Restriction	The scoring function name is a combination of the model name and the output variable name. The scoring function name cannot exceed 30 characters. For more information, see Scoring Function Names.
Requirement	If you use scoring functions, the model name must be a valid SAS name that is ten characters or fewer. If you use 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. For more information, see the SAS Foundation system requirements documentation for your operating environment.
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.
Restrictions	If you use scoring functions to run scoring models, the maximum number of output variables is 128. If you use the SAS Embedded Process and Teradata version 13.1 or 14.0, the maximum is 1024. If you use the SAS Embedded Process and Teradata version 14.10, the maximum is 2048.
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
Requirements	If you use 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.
Requirements	The maximum database name length is 30 characters, and it must be a valid Teradata database name.
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.
Interactions	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 . 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 can result in a significant performance gain.

OUTDIR=diagnostic-output-directory

specifies a directory that contains diagnostic files.

Produced files 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 as 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.
