Running the %INDNZ_PUBLISH_MODEL Macro

%INDNZ_PUBLISH_MODEL Macro Run Process

To run the %INDNZ_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.
Start SAS 9.3 and submit the following commands in the Program Editor or Enhanced Editor:
```
%indnzpm;
%let indconn = server=myserver user=myuserid password=XXXX database=mydb;
```
For more information, see %INDNZPM Macro and the INDCONN Macro Variable.
Run the %INDNZ_PUBLISH_MODEL macro.

For more information, see %INDNZ_PUBLISH_MODEL Macro Syntax.

Messages are written to the SAS log that indicate the success or failure of the creation of the scoring functions.

Note: The %INDNZ_PUBLISH_JAZLIB macro and the %INDNZ_PUBLISH_COMPILEUDF macro (if needed) must be run before you can publish your scoring models. Otherwise, the %INDNZ_PUBLISH_MODEL macro fails. These macros are typically run by your system or database administrator. For more information about these macros, see the SAS In-Database Products: Administrator's Guide.

%INDNZPM Macro

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

macro indnzpm not defined

INDCONN Macro Variable

The INDCONN macro variable is used to provide credentials to connect to Netezza. You must specify server, user, password, and database information to access the machine on which you have installed the Netezza data warehouse. You must assign the INDCONN macro variable before the %INDNZ_PUBLISH_MODEL macro is invoked.

Here is the syntax for the value of the INDCONN macro variable for the %INDNZ_PUBLISH_MODEL macro:

SERVER=serverUSER=user PASSWORD=password DATABASE=database

Arguments

SERVER=server: specifies the Netezza server name or the IP address of the server host.

USER=user: specifies the Netezza 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 Netezza 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 Netezza database that contains the tables and views that you want to access.

Tip

The INDCONN macro variable is not passed as an argument to the %INDNZ_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 to the file so that others cannot access the user credentials.

);

Note: Do not enclose variable arguments in single or double quotation marks. This causes the %INDNZ_PUBLISH_MODEL macro to fail.

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.

Requirement	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 Netezza database.

Restriction	The scoring function name is a combination of the model and output variable names. A scoring function name cannot exceed 128 characters. For more information, see Scoring Function Names.
Requirement	The model name must be a valid SAS name that is ten characters or fewer. 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 Netezza scoring functions. For more information about the EM_ output variables, see Fixed Variable Names and Scoring Function Names.

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	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 Netezza database to which the scoring functions and formats are published.

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 %INDNZ_PUBLISH_MODEL Macro Run Process.
Tip	You can publish the scoring functions and formats to a shared database where other users can access them.

DBCOMPILE=database-name

specifies the name of the database where the SAS_COMPILEUDF function is published.

Default	SASLIB
See	For more information about publishing the SAS_COMPILEUDF function, see the SAS In-Database Products: Administrator's Guide.

DBJAZLIB=database-name

specifies the name of the database where the SAS formats library is published.

Default

SASLIB

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.

Default
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 a new function.

REPLACE: overwrites the current function, if a function by the same name is already registered.

DROP: causes all functions for this model to be dropped from the Netezza database.

Default	CREATE
Tip	If the function was published previously and you specify ACTION=CREATE, you receive warning messages that the function already exists and you are prompted to use REPLACE. If you specify ACTION=DROP and the function does not exist, an error message is issued.

MODE= FENCED | UNFENCED

specifies whether running the code is isolated in a separate process in the Netezza database so that a program fault does not cause the database to stop.

Default	FENCED
Restriction	The MODE= argument is supported for Netezza 6.0. The MODE argument is ignored for previous versions of Netezza.
Tip	There are limited resources available in Netezza when you run in fenced mode. For example, there is a limit to the number of columns available.
See	Modes of Operation

IDCASE= UPPERCASE | LOWERCASE

specifies whether the variable names in the generated sample SQL code (SampleSQL.txt) appear in uppercase or lowercase characters.

Default	UPPERCASE
Tip	When you specify the IDCASE argument, the %INDNZ_PUBLISH_MODEL macro first determines which release of Netezza is being used. If Netezza release 5.0 or later is being used, the macro then checks to see whether the LOWERCASE or UPPERCASE option is set for the database by using SQL statement SELECT IDENTIFIER_CASE. If the value of the IDCASE argument is different from the case configuration of the database, the macro overwrites the value of the IDCASE option and uses the case configuration of the database. If an earlier release of Netezza is being used, the macro uses the value of the IDCASE argument.
See	Using the Scoring Functions for more information about the SampleSQL.txt file

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 %INDNZ_PUBLISH_MODEL macro has two modes of operation: fenced and unfenced. You specify the mode by setting the MODE= argument.

The default mode of operation is fenced. Fenced mode means that the scoring function that is published is isolated in a separate process in the Netezza database when it is invoked. An error does not cause the database to stop. It is recommended that you publish the scoring functions in fenced mode during acceptance tests.

When the scoring function is ready for production, you can run the macro to publish the scoring function in unfenced mode. You could see a performance advantage if the scoring function is published in unfenced mode.

Note: The MODE= argument is supported for Netezza 6.0. The MODE argument is ignored for previous versions of Netezza.

Model Publishing Macro Example

%indnzpm;
%let indconn = server=netezbase user=user1 password=open1 database=mydb;
%indnz_publish_model(dir=C:\SASIN\baseball1, modelname=baseball1);

This sequence of macros generates a separate .c file for each output parameter of interest. Each output stub calls into a shared scoring main that is compiled first. The %INDNZ_PUBLISH_MODEL macro also produces a text file of Netezza CREATE FUNCTION commands as shown in the following example.

Note: This example file is shown for illustrative purposes. The text file that is created by the %INDNZ_PUBLISH_MODEL macro cannot be viewed and is deleted after the macro is complete.

CREATE FUNCTION baseball1_EM_eventprobablility
(
"CR_ATBAT" float,
"CR_BB" float,
"CR_HITS" float,
"CR_HOME" float,
"CR_RBI" float,

"LEAGUE" varchar(31),
"NO_ASSTS" float,
"NO_ATBAT" float,
"NO_BB" float,
"NO_ERROR" float,
"NO_HITS" float,
"NO_HOME" float,
"NO_OUTS" float,
"NO_RBI" float,
"NO_RUNS" float,

DEPENDENCIES dbjazlib..sas_jazlib  /* if TwinFin system */

After the scoring functions are installed, they can be invoked in Netezza using SQL, as illustrated in the following example. Each output value is created as a separate function call in the select list.

select baseball1_EM_eventprobability
( 
"CR_ATBAT",
"CR_BB",
"CR_HITS",
"CR_HOME",
"CR_RBI",

"NO_ATBAT",
"NO_BB",
"NO_ERROR",
"NO_HITS",
"NO_HOME",
"NO_OUTS"
) as homeRunProb from MLBNetz;

Netezza Permissions

You must have permission to create scoring functions and tables in the Netezza database. You must also have permission to execute the SAS_COMPILEUDF, SAS_DIRECTORYUDF, and SAS_HEXTOTEXTUDF functions in either the SASLIB database or the database specified in lieu of SASLIB where these functions are published.

Without these permissions, the publishing of a scoring function fails. To obtain these permissions, contact your database administrator.

For more information about specific permissions, see Netezza Permissions in SAS In-Database Products: Administrator's Guide.
