Heap Use and Management

Heap Use and Management

The Pivotal GemFire resource manager works with your JVM's tenured garbage collector (GC) to control heap use and protect your member from hangs and crashes due to memory overload.

  • How the Resource Manager Works
    The GemFire resource manager prevents the cache from consuming too much memory by evicting old data. If the garbage collector is unable to keep up, the resource manager refuses additions to the cache until the collector has freed an adequate amount of memory.
  • Control Heap Use with the Resource Manager
    Resource manager behavior is closely tied to the triggering of GC activities, the use of concurrent GCs in the JVM, and the number of parallel GC threads used for concurrency.
  • Resource Manager Example Configurations
    These examples set the critical threshold to 85 percent of the tenured heap and the eviction threshold to 75 percent.
