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
smtty install 安装xlfrte 包，重新执行root.sh脚本即可.
