License limits
This article will focus on explaining the license limits and how to handle them. Once Server is installed and running, you can inspect the active license limits using theAdministration > Manage Licensesnavigation menu within the RapidMiner Server web application.
What are logical processor limits
RapidMiner Server and each Job Container make 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 theSystem Settings(rapidminer.general.number_of_threads) and in thecontainer.propertiesfile of the Job Agent (/config/container.properties). Some license versions of RapidMiner Server also restrict the number of global concurrently running processes to one. If the license limit is not displayed the active license is not bound to any limit.
The execution of Web Services is also limited by the number of logical processors available (as limited by your license). You can also configure the maximum number of threads for each web service call in theSystem Settings(com.rapidanalytics.webservices.concurrency).
What are memory limits
RapidMiner Server and each Job Container uses a specified amount of memory. The max memory setting is bound to your license and is defined during installation. In case of RapidMiner Server the setting is persisted in themax-memory.conffile. 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.
The number of spawned Job Containers and the memory per Job Container can be configured within the进行file of the Job Agent (/home/config/agent.properties). You need to take care that thetotal memoryconsumption does not exceed your license limits, or the Job Agent won't start. If an old license expires while the Job Agent is running, and thetotal memoryconsumption exceeds the new license limits, the Job Agent will drop jobs. The formula for calculating thetotal memoryis:Number of spawned Job ContainersxMemory per Job Container.
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 theManage Licenseor theServices页面。如果许可证限制displayed the active license is not bound to any limit.
