Each application server sends a ping signal to the
administrative server or nodeagent according to the Ping Interval
set for that server. The administrative server or nodeagent waits for the
ping signal from each Application Server according to the settings and if
a ping signal is not sent according to the Ping Timeout value,
the administrative server or nodeagent assumes that the Application Server
has become unresponsive and tries to restart the Application Server.
For some applications, the default value (200 seconds for V4 and 300
seconds for V5 and V6) for Ping Timeout might be too small. In
such cases, tune this value to avoid an unnecessary restart of application
servers.
Note: Under normal circumstances, it is not advisable to disable
the ping mechanism.
Disabling the ping mechanism
For V4
In the administrative console, go to the Advanced tab of the
Application Server, and specify the Ping Interval as 0 (zero) seconds to
disable the ping mechanism.
For V5
In the Administrative console, click Servers >
Server_Name > Process Definition >
Monitoring Policy. Specify the Ping Interval as 0 (zero) seconds to
disable the ping mechanism.
For V6
In the Administrative console, click Servers >
Server_Name > Java and Process Management >
Monitoring Policy. Specify Ping Interval as 0 (zero) seconds to
disable the ping mechanism.
By setting the Ping Interval to 0 (zero), the administrative server or
nodeagent does not communicate with the Application Server to verify if
the server is running.
