Hi Steven,
unfortunately the output is a little bit unreadable, but if i see it correctly your Oracle process is running fully on CPU and the overall CPU summary is showing a lot of SYS activity.
However the best way would be to truss / tusc your Oracle process based on your described Oracle behavior (and cmd output). You may need to truss / tusc the whole startup procedure and not only the currently running process to get an idea of the whole system call flow. There are other debug possibilities as well, but i would start with truss / tusc.
Regards
Stefan
