exec(): 0509-036 Cannot load program /home/sybase/ASE-12_5/bin/dataserver because of the following errors:
0509-130 Symbol resolution failed for /usr/ccs/lib/libc.a[aio_64.o] because:
0509-136 Symbol kaio_rdwr64 (number 0) is not exported from dependent module /unix.

0509-136 Symbol aio_nwait_timeout64 (number 7) is not exported from dependent module /unix.
0509-028 Symbol used in ? type does not match exported type.
0509-192 Examine .loader section symbols with the
'dump -Tv' command.

检查后发现AIX的异步IO没打开。修改参数后，重启机器。

chdev -l aio0 -P -a autoconfig='available'

再次利用rs文件新建实例，正常执行！

附：

AIX查看aix状态： AIX 查看aio状态

【故障处理】因AIX异步IO没有开启导致SQL*Plus不可用
