Heap size is important when building an environment, as it will dictate the amount of memory available for FlexNet Manager for Engineering Applications. For example, if your server has 50 GB of RAM, you can limit FlexNet Manager for Engineering Applications to only use 16 GB by configuring the heap size.
The cause of many performance issues with FlexNet Manager for Engineering Applications is a lack of resources as the environment grows larger. As your environment grows, the number of resources required to keep the application performing at an optimal level will increase. Increasing the heap size can resolve most slowness/performance issues.
We recommend a minimum of 16 GB of RAM for each the Admin and Reporting servers. These specifications are based on a small environment. The larger the environment, the more resources you will need.
Factors that will affect RAM requirements:
The number of agents/license servers/vendors
The amount/size of .RL files imported into FlexNet Manager for Engineering Applications
Users' usage of the application, specifically the reporting functionality
The size of your database
