Snf that might mean your system is not quite busy. You can sample v$session_wait (or use ASH) and see which process is that. After that you can add this even as idle for statspack or whatever you use. Alternatively, you might just stop looking at system wide metrics (though, some might disagree). ;-) On 11/6/06, fairlie rego <fairlie_r@xxxxxxxxx> wrote:
Hi, AFAIK ASM Background timer wait event is an idle wait event like PMON timer and SMON timer and is set when the ASMB background process is waiting on messages from the ASM instance.

I'm more interested in confirming if this is just an idle event used by ASM to indicate that it has nothing to do. The system (10gR2, Solaris 64-bit, EMC SAN, db of about 40GB) is running relatively well, but we're curious nonetheless. Nothing comes back from [technet | www | tahiti | docs].oracle.com, nor much from Google (just a few appendix listings classing it as an idle event). Anyone have any background on it?
