How to trace processes in detail

AB007Dec 19 2012 — edited Dec 21 2012

Hello,

I have a Sun (5.10 Generic_144488-12 sun4v sparc SUNW,SPARC-Enterprise-T5220) RAC cluster running 11.2.0.3 GI & RDBMS, connected to a storage array through Fibre channel. But for some reason we see a horrible I/O response time @ teh DB level, which unfortunately doesn't sync up with the HOST or Storage logs, or in other words, systems or storage admins don't see any waits.

So my question is, is there any tool we can use to trace each and every event @ the OS/kernel level? Something like the strace, and also how to interpret that log file!?

Thanks in advance,
aBBy.
