The following steps are executed to monitor the sanity of Apache Tomcat.
Sleeps for Thorough_probe_interval.
Pings the Host, which is configured in the Apache Tomcat HA parameter file.
Connects to the Apache Tomcat via Host and Port. If the connection is successful it sends the TestCmd and tests whether the ReturnString comes back. If it fails, it is rescheduled after 5 seconds. If this fails again, then the probe will restart the Apache Tomcat.
The ReturnString cannot be Connection refused because this string will be returned if no connection is possible.
If the Apache Tomcat process has died, pmf will interrupt the probe to immediately restart the Apache Tomcat.
If the Apache Tomcat is repeatedly restarted and subsequently exhausts the Retry_count within the Retry_interval, then a failover is initiated for the resource group onto another node. This is done if the resource property Failover_enabled is set to TRUE.
