This topic describes the gc command in gfsh, the VMware Tanzu GemFire command-line interface.
Use this command to force garbage collection (GC) 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.
Syntax:
gc [--groups=value(,value)*] [--member=value]
| Name | Description |
|---|---|
| ‑‑groups | One or more groups of members on which garbage collection will be forced. |
| ‑‑member | Name/ID of the member on which garbage collection will be forced. |
