Re: How to enable Async I/O on Solaris

The default for disk_async_io is true.

Either async i/o is support or not. T'ain't supported on Solaris unless you have raw devices.

Oracle defaults async_io to true on Solaris for two reasons: 1) If not available, the call _should_ fail quickly, Oracle retries without async.

2) Just in case you have one or more raw devices, Oracle will automatically issue async_io calls utilizing them.

I'm not using raw. I have disk_async_io=false in my init files. ----- Original Message -----
