Object

scalar r/w Enumeration

This object makes it possible to remotelly trigger the
Garbage Collector in the JVM.
          
This object's syntax is an enumeration which defines:
          
* Two state values, that can be returned from a GET request:
          
 unsupported(1): means that remote invocation of gc() is not 
                 supported by the SNMP agent.
 supported(2)  : means that remote invocation of gc() is supported
                  by the SNMP agent.
          
* One action value, that can be provided in a SET request to
 trigger the garbage collector:
          
 start(3)      : means that a manager wishes to trigger
                 garbage collection.
          
* Two result value, that will be returned in the response to a
 SET request when remote invocation of gc is supported
  by the SNMP agent:
          
  started(4)    : means that garbage collection was 
                 successfully triggered. It does not mean 
                 however that the action was successfullly
                 completed: gc might still be running when
                 this value is returned.
  failed(5)     : means that garbage collection couldn't be
                 triggered.
          
* If remote invocation is not supported by the SNMP agent, then
 unsupported(1) will always be returned as a result of either
 a GET request, or a SET request with start(3) as input value.
          
* If a SET request with anything but start(3) is received, then
  the agent will return a wrongValue error.
