Running the mapgen Command Line Program

Use the mapgen
command line program to create the mappings from a mapping template.

mapgen
uses the following syntax:

mapgen
<-t> VisioDrawingFile
<-p> ParameterFile
<-o> MappingFile
[-d] TableDefinitionDir

The following table describes the mapgen
options and arguments:

Option	Argument	Required/ Optional	Description
-t	VisioDrawingFile	Required	Name of the Visio drawing file for the mapping template. The file has a .vsd extension for Microsoft Visio 2010 and previous versions. You can save the file with a .vsdx extension for Microsoft Visio 2016. To create the file, save the mapping template in Mapping Architect for Visio as a Visio drawing file. If the file is not in the current working folder, add a path name in front of the file name.
-p	ParameterFile	Required	Name of the mapping template parameter file. Mapping Architect for Visio automatically creates the parameter file when you publish the mapping template. The filename is <mapping template name>_param.xml. If the file is not in the current working folder, add a path name in front of the file name.
-o	MappingFile	Required	Name of the PowerCenter mapping file used to create mappings from the mapping template. The file has a .xml extension. If you do not want to create the file in the current working folder, add a path name in front of the file name.
-d	TableDefinitionDir	Conditional	Name of the folder where the source and target definition files are located. Required if the files are not located in the default folder. By default, the source and target definition files are stored in the following location: \< PowerCenterInstallationDir >\Clien t\ MappingTemplate\tabledefs

Before you run mapgen
, verify that you have all the files required by the program.

To run the mapgen program:

Close the referenced Visio drawing file.

If the .vsd or .vsdx file is open when you run
mapgen
, mapgen
generates a warning that the file is open for modification.

In the Designer or Repository Manager, export the source and target definitions for the sources and targets you want to use in the mappings to be created by the mapgen
program.

By default, mapgen
looks for the source and target definition files in the following folder:

<PowerCenterInstallationDir>\client\MappingTemplate\tabledefs

If you export the files to another folder, provide the folder name when you run the mapgen
program.

Open a command line window on the machine where Mapping Architect for Visio is installed.

Go to the Mapping Architect for Visio folder.

By default, Mapping Architect for Visio is installed in the following location:

<PowerCenterInstallationDir>\client\MappingTemplate\

Run mapgen.exe.

After you generate the mapping file, import the file into the repository to view all the generated mappings.
