oracle listener error times out

Hi All, 

We are experiencing VCS warning messages saying Oracle listener resource has mied out. It has happened for few times. 

But we found the system is working fine and no issue. And at the same time the CPU usage is quite high.

The question here is how we can confirm the high CPU that caused the time out issue. 

The VSC version is 4.o and here are the setting of the resource.

 

hatype -display Netlsnr

You can increase the MonitorTimeout (current value is 60 sec).

Before you do that, please see this recommendation in the VCS User Guide:

For best results, VERITAS recommends measuring the time it takes to bring a resource online, take it offline, and monitor before modifying the defaults. Issue an online or offline command to measure the time it takes for each action. To measure how long it takes to monitor a resource, fault the resource and issue a probe, or bring the resource online outside of VCS control and issue a probe.

 

You will need to do this during high CPU usage.

btw, is your engine_A.log reports anything on the Netlsnr timeout?
