Hi, list.
 

Has anyone used "event 10351" ?
 

I'm checking for Async I/O on Solaris 2.6, Oracle 7.3.4
It works just fine over Raw Devices and It does not over FS (as usual). I can see this on a OS trace.
 

But searching on metalink I've found
this:
 

"Event 10351 is also used to get information whether Oracle is using this aio calls or not. "
 

I've tried it (with level 2) and the result was this:
 

<FONT face=Arial

*** SESSION ID:(5.1)
2001.02.26.18.17.41.000(ssfiasi)    do_asy_ok = 1, nreqs = 8(ssfsync)    entry, nreqs = 8, start = 0, flags = 0x2
<FONT face=Arial

size=2>----------------------------------------------------------------------------

 

Does "do_asy_ok" mean that async i/o is not working?
 

Can I see more info about this, how can I find it?
 
 
 
 

Over raw devices I get the same
output.
