Re: ADX 1000 Session Disconnection for Oracle EBS Application

Hi Iqbal,

 

Which application port are the clients connecting to? 22, 80, 8000?

 

It may be that the ports are failing heath checks periodically, which would cause the client to disconnect, you should be able to establish this by vieing the log.  It may also be worthwhile adding keepalive to the healthcheck on the real servers

 

Hope this helps

 

Regards

Mick

Re: ADX 1000 Session Disconnection for Oracle EBS Application

Hi,

 

As you have said it seems from the logs that you have included the Active-standby pair of ServerIron are failing over as periodically not receiving PDU

 

Can you run the command show serv backup several times and send the results

 

Thanks

Mick
