exec(): 0509-036 Cannot load program /usr/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:

0509-192 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'
新建server 即可正常安装。
