aioservers on AIX
I have a 11.2.0.1 database on IBM AIX on POWER Systems (64-bit) (6.1).
# ps -k | grep aioserver
shows 24 aioserver processes even after Oracle Database is shutdown. Only Oracle is installed on this server
I found some documents saying that once AIX allocates an aioserver, it remains until the next reboot and that even root user cannot kill it, because they are in kernel space.
Why are these not killed automatically? What is the purpose to keep them?
Is this the expected behavior or we should worry about these processes?
Is a big lost for memory consumption and CPU to have these processes or once they are not doing any I/O are not consuming anything?
