Troubleshooting
Problem
One of our customers uses Modeler Server 18.2.1 and C&DS (Collaboration and Deployment Services) 8.2.1 on Windows.
He runs many jobs with Modeler streams in C&DS (Collaboration and Deployment Services). Observing memory utilization on the Modeler Server host operating system the customer has noticed that Modeler Server uses more frequent of Page File memory than RAM (Random Access Memory) memory. This is strange because there is a lot of RAM memory in the system (64GB) and Java Virtual Machine memory is also high (-xmx, 32GB). The utilization of the RAM is usually less than 4GB while at the same time Page File memory utilization is higher then 20GB. Why this?
How to force Modeler Server to use RAM memory (quicker) instead of page file?
It will be enough if you point us that place in the Modeler documentation where increasing the available memory is described:
Symptom
In some articles about virtual memory and that it is handled transparently by the OS (Operational System). Java (and probably Modeler Server too) does not know or care whether the memory given to it is actual RAM (Random Access Memory) or partially in a swap file. But for the better performance it would be more rational to use quicker RAM memory, especially when it is available in the big amount.
