Force GC (Garbage Collection) on a member or members.

The default is for garbage collection to occur on all caching members.

The gfsh gc command should be used only in non-production environments. This is a forced GC event and not always handled well by the garbage collector outside of normal GC processing. This can cause slow-responding members to be perceived as unresponsive and disconnected from the cluster.

Availability: Online. You must be connected in gfsh to a JMX Manager member to use this command.


gc [--groups=value(,value)*] [--member=value]

Name Description
--groups One or more group(s) of members on which garbage collection will be forced.
