SOLVED Weblogic 14 option wlsdm.agent.extendedBackendMonitoringEnabled=true dont start server

[arturrgdietrich]

Weblogic 14:
if “-Dwlsdm.agent.extendedBackendMonitoringEnabled=true” option is included in start options from managed server it does not start. Removing this option it stars correctly!

ERROR:

to retry (attempt number 1 of 3).>
<May 3, 2024 11:33:05 AM ART> <Unable to connect to the Administration Server. Waiting 5 second(s)
to retry (attempt number 2 of 3).>

Is there any solution for this ? What benefit will I lose if I don’t use this option?

If -DUseSunHttpHandler=true parameter is added to your WebLogic managed server probably you are having below known issue. Please consider to apply below solution to your case.

Known Issue - Conflict Between DUseSunHttpHandler and Dwlsdm.agent.extendedBackendMonitoringEnabled: When both -DUseSunHttpHandler=true and -Dwlsdm.agent.extendedBackendMonitoringEnabled=true are added to a WebLogic ManagedServer instances simultaneously, an error occurs: "java.lang.NoClassDefFoundError: com/vopm/collector/HTTPData" To resolve this issue, remove one of the conflicting parameters. Consider removing "-DUseSunHttpHandler=true" argument for monitoring remote HTTP(s) outbound connections if it is technically possible

Hi,

I see that you have passed this parameter to Admin Server. Can you give the relevant parameter on the instance and then restart it? “-Dwlsdm.agent.extendedBackendMonitoringEnabled=true”

Kind regards.

@can-sahin-wlsdmteam i think you did not understand. For AdminServer we dont put any parameter. But if you put the mentioned parameter to any Managed Server, this same Managed Server can not contact the AdminServer.

Hi,
With this parameter you are able to monitor your external outbound HTTP(s) services. This feature is not related with AdminServer. Could you please send the all AdminServer WLSDM logs and agent WLSDM logs which is available under $DOMAIN_HOME/WLSDM/logs folder.

• Is there any exception available for this log?
• Is this -DUseSunHttpHandler=true parameter is added on your managed server?
