| Problem | Under some circumstances it is necessary to disable the ping mechanism to avoid a restart of the Application Server even when the server is unresponsive.
Note: Under normal circumstances, it is not advisable to disable the ping mechanism. | | | | Solution |
Understanding the ping mechanismEach application server sends a ping signal to the administrative server according to the Ping Interval set for that server. The administrative server 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 assumes that the Application Server has become unresponsive and tries to restart the Application Server.For some applications, the default value of 200 seconds for Ping Timeout might be too small. In such cases, tune this value to avoid an unnecessary restart of application servers.Disabling the ping mechanismIn the administrative console, go to the Advanced tab of the Application Server, and specify the Ping Interval as 0 seconds to disable the ping mechanism. By setting Ping Interval to 0, the administrative server does not communicate with the Application Server to verify if the server is running. | |
