Setting the Method Server HEAP Size
It is recommended that the default Java heap size for each method server be set to 512 MB in order to cope with large CAD application data sets that are common to the products developed by CAD users.
You can set the Java heap size and cache settings for the method server using the Windchill Configuration Assistant. For more information, see Running the Windchill Configuration Assistant.
