nm. Output similar to the following is desired.
$ ldd $ORACLE_HOME/bin/oracle | grep libaio libaio.so.1 => /usr/lib/libaio.so.1 (0x0093d000) $ nm $ORACLE_HOME/bin/oracle | grep io_getevent w io_getevents@@LIBAIO_0.1
Verify whether running Oracle processes are making asynchronous I/O calls by inspecting
