AIX上未启动异步IO导致Sybase服务创建失败

在AIX5.3上使用资源文件新建Sybase ASE12.5.2实例时,报如下的错误:

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:

0509-028 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
