场景：
Aix 7.2 上安装Oracle 18.4 RAC 执行root.sh脚本，ASM failed to start ！查看日志文件：ORA-40238: invalid linear algebra shared library /u01/app/oracle/product/18.0.0/grid_1/lib/libora_netlib.so
原因：Fortran Runtime 包不存在
lslpp -L all | grep -i "Fortran Runtime"
解决方案：
操作系统安装所需要的包：Install Fortran Runtime package (15.1) in the operating system and retry the instance startup
smitty install 安装xlfrte 包，重新执行root.sh脚本即可.
