To trace the http level connections by the OMS.

The OMS communicates with many other components (Agent, MOS, etc.) over HTTP(S). There is sometimes a need to trace what is happenning at the HTTP level. One way to achieve this is to use tcpdump or a network sniffing tool such as Wireshark to sniff the traffic.  However, this can be intrusive and difficult to setup. An alternative way is to turn on debug at the HTTPClient layer.

The HTTPClient layer is provided as a oracle.http_client_11.1.1.jar from FMW. It's used both on the Agent and on the OMS side.

OMS Side: $MIDDLEWARE_HOME/oracle_common/modules/oracle.http_client_11.1.1.jar
Agent Side: $AGENT_BASE/core/
