OC4j ping attempt timed out

Question

Hi
We have a standalone oracle application server 10.1.3 with a J2EE application deployed to it which provides webservices to support a website. Intermittently the performance of the application deteriorates and then the oc4j instance restarts itself.
We see the following entries in opmn.log
OC4J ping attempt timed out
[libopmnoc4j] Process Ping Failed: oc4j~<instance name>~default_island~1 (1132071111:2340)
[libopmnoc4j] Process Unreachable: oc4j~<instance name>~default_island~1 (1132071111:2340)
[pm-process] Restarting Process: oc4j~<instance name>~default_island~1 (1132071111:2340)

[libopmnoc4j] Forcefully Terminating Process: oc4j~<instance name>~default_island~1 (1132071111:2340)

[pm-process] Process Alive: oc4j~<instance name>~default_island~1 (1132071111:2996)
Following note 761675.1 on metalink we added the following parameters to opmn.xml
   <ping timeout="60" interval="60"/>"
   <data id="reverseping-failed-ping-limit" value="5" />However the note does not specify where in opmn.xml the lines should be placed. We are hoping that these parameters will prevent the oc4j instance from restarting when the performance deteriorates.
I managed to get the parameters into a valid place in the file but am concerned that they are not in the correct place to have the desired effect. The relevant part of opmn.xml below - does anyone know if the parameters are in the correct place?

ps the lines I added are supposed to be in bold

Answer 1

Should be something like this
<process-type id="home" module-id="OC4J" status="enabled">
<start timeout="600" retry="2"/>
<stop timeout="120"/>
<restart timeout="720" retry="2"/>
<ping timeout="40" interval="30" retry="2"/> (1)
</process-type>
Greetings.
