public class PassiveSnmpContext

extends SnmpContext

This class contains the SNMP v1 context that is needed by a Pdu to send a SNMP v1 request in environments where thread creation is unwanted.

This extends SnmpContext so that it does not create any threads to send pdus. It must be used with the PDU class PassiveTrapPduv1. The original purpose of the Passive classes is to allow the stack to be used in environments where thread creation is unwanted, eg database JVMs such as Oracle JServer. See RFC 1905.

See notes on how to send traps in an Oracle JServer environment.

Method Detail

activate

protected void activate()

Overrides the AbstractSnmpContext.activate() to do nothing. This prevents the creation of threads in the base class.
