    -XX:+HeapDumpOnCtrlBreak option using hotspot 1.6.0.10 on HP-UX B11.31

    963955
      Hi, we are using jvm argument -XX:+HeapDumpOnCtrlBreak for collecting the heapdump on HP-UX environment . Each time when we trigger the heapdump command (kill -3 <pid>) we are observing increase(spike) in database response time and database commit response time. Please share your ideas:

      Environment details:
