License limits
RapidMiner Server 7.2 comes with a reworked license framework. This article will focus on explaining the introduced limits and how to handle them. Once Server is installed and running, you can inspect the active license limits using the Administration > Manage Licenses navigation menu within the RapidMiner Server web application.
What are logical processor limits
RapidMiner Server makes use of RapidMiner Studio to execute processes. Some operators of RapidMiner Studio are able to perform the computation of complex tasks in a parallel way. For every parallel execution a new thread will be created which can be processed by a logical processor. The number of logical processors and thus the maximum number of threads is limited by your license and can also be specified in the System Settings (rapidminer.general.number_of_threads). Some license versions of RapidMiner Server also restrict the number of global concurrently running processes to one. You can also manually define this limit by using the System Setting com.rapidanalytics.process.scheduled.local_processes_concurrent_limit. If the license limit is not displayed the active license is not bound to any limit.
What are memory limits
RapidMiner Server uses a specified amount of memory. The max memory setting is bound to your license and is defined during installation. The setting is persisted in the max-memory.conf file. If you start RapidMiner Server with a memory settings which exceeds your license limit, the following web page will be displayed. At this point you can either provide a license which fits your needs or reduce the memory settings and restart RapidMiner Server.
What are web service limits
RapidMiner Server is able to expose processes as web services. These web services can then be utilized by clients or other services to solve arbitrary tasks. The amount of allowed web service calls per day is bound to your license. To display the number of processed calls visit the Manage License or the Services page. If the license limit is not displayed the active license is not bound to any limit.
