The default value for the Modeling service’s maximum memory pool size is set during the installation of the Modeling service. The value is set based on the machine’s RAM size. For example, 1GB for a machine with RAM of 8-32GB or less, 2GB for a machine with RAM of 64-128GB.
For details, please refer to see Modeling Service Configuration Properties.
However, in a Strategy Cloud Platform environment, the default setting is always 1GB, even when the user configures the machine with 64GB or more memory.
When a Strategy Cloud Platform environment is deployed, first it creates a new environment based on the pre-created template. Then it adjusts the machine configurations (e.g., RAM size) according to the user’s selection. As the template machine is with RAM of 30.5GB, the maximum memory pool size for Modeling service is configured as 1GB.
The workaround for this defect is to manually change the property MODELSERVICE_JAVA_MAX_MEMORY in modelservice.ini.
