aix平台执行sqlplus报：0509-130 Symbol resolution failed for /usr/lib/libc.a[aio_64.o]

客户说执行sqlplus时报错，详细见下：

$ sqlplus 'sys/ligle as sysdba'

看信息知道是可能跟aio有关系，查询aio是否开启？

root@hiuset_bas1:/>lsattr -El aio0

autoconfig defined STATE to be configured at system restart True
fastpath enable State of fast path True
kprocprio 39 Server PRIORITY True
maxreqs 4096 Maximum number of REQUESTS True
maxservers 80 MAXIMUM number of servers per cpu True
minservers 1 MINIMUM number of servers True

打开aio：

root@hiuset_bas1:/>chdev -P -l aio0 -a autoconfig='available'
aio0 changed
root@hiuset_bas1:/>lsattr -El aio0
autoconfig available STATE to be configured at system restart True
fastpath enable State of fast path True
kprocprio 39 Server PRIORITY True
maxreqs 4096 Maximum number of REQUESTS True
maxservers 80 MAXIMUM number of servers per cpu True
minservers 1 MINIMUM number of servers True

在执行sqlplus登陆db，没有问题了~
