Configuring aio
- create the
/dev/async
character device
- configure the async driver in the kernel:
this will require a kernel rebuild and reboot.
- set
max_async_ports
:
max_async_ports
limits the maximum number of processes that can concurrently use /dev/async
. Set this parameter to the sum of ‘processes’ from init.ora
+ number of background processes. The background processes started at instance startup will open /dev/async
twice.
If max_async_ports
is reached, subsequent processes will use synchronous I/O
