Question:
We are experience 100% CPU usage issue after the server runs for 20-30mins. We are trying to troubleshoot.
I have read that we can use jstack to generate dump of high cpu thread.
However in Amazon ami jstack is not installed.

Is there a way I can install jstack without reinstalling oracle build?
Also is there any other solution to get dump?
