问：有些 AIX 系统下的 DB2 用户在试图使用 db2start 命令启动实例时，遇到了类似下述报错:

exec(): 0509-036 Cannot load program db2start because of the following
errors:
0509-130 Symbol resolution failed for
/usr/lib/threads/libc.a(aio.o) because:
0509-136 Symbol kaio_rdwr (number 0) is not exported from
dependent module /unix.
0509-136 Symbol listio (number 1) is not exported from
dependent module /unix.
0509-136 Symbol acancel (number 2) is not exported from

0509-136 Symbol aio_nwait (number 4) is not exported from

0509-130 Symbol resolution failed for
/usr/opt/db2_08_01/lib/libdb2e.a(shr.o) because:
0509-136 Symbol aio_nwait (number 416) is not exported from
dependent module /usr/lib/threads/libc.a(aio.o).
0509-192 Examine .loader section symbols with the
'dump -Tv' command.

　　实例启动的操作也因此失败，这一问题与 AIX 操作系统上 KAIO 是否启用有关。
