Model Creation

The Content Management Service performs compilation operations for probabilistic models. As probabilistic model compilation is memory-intensive, you may need to increase the heap size available to the Content Management Service.

When you compile a model, check the Content Management Service logs at the following location for errors:

$INFA_HOME/logs/[nodename]/services/ContentManagementService

If there is insufficient memory to compile the model, you will see an error like this:

com.informatica.cms.service.webapp.ContentManagementServiceServlet$ContentManagementServiceDefaultUncaughtExceptionHandler uncaughtException
 WARNING: uncaughtException in CMS - Java heap space

When you see such an error, the Content Management Service has insufficient memory to compile the model, and you must increase the java heap size for the process. You can increase the java heap size in the Administrator tool. Navigate to the Processes tab on the Content Management Service, and update the Maximum Heap Size advanced property.

You specify the heap size in megabytes, for example 2048M, or gigabytes, for example 2G. Note the syntax in this case, as mistakes are common. After you update the heap size, restart the Content Management Service.

The average model consumes approximately 50 MB in physical disk space.

If you are not concerned about the probabilistic score output from a Labeler or Parser transformation, leaving the score port unconnected on the transformation will improve performance.
