MEMORY MANAGEMENT FOR MULTIPLE PROCESS INSTANCES - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18337418 Titled 'MEMORY MANAGEMENT FOR MULTIPLE PROCESS INSTANCES'
Simplified Explanation
This abstract describes a method for efficiently managing memory in multiple instances of a process, such as SQL servers. The method involves determining the memory usage of each process instance and calculating the cost of each memory unit. Based on this information, a certain number of memory units are identified to be reclaimed in each process instance in order to minimize the overall cost. This count of memory units to be reclaimed is then communicated to each process instance.
Original Abstract Submitted
Intelligent memory brokering for multiple process instances, such as relational databases (e.g., SQL servers), reclaims memory based on value, thereby minimizing cost across instances. An exemplary solution includes: based at least on a trigger event, determining a memory profile for each of a plurality of process instances at a computing node; determining an aggregate memory profile, the aggregate memory profile indicating a memory unit cost for each of a plurality of memory units; determining a count of memory units to be reclaimed; identifying, based at least on the aggregate memory profile and the count of memory units to be reclaimed, a count of memory units to be reclaimed within each process instance so that a total cost is minimized to reclaim the determined count; and communicating, to each process instance having identified memory units to be reclaimed, a count of memory units to be reclaimed within the process instance.
