想在aix 中安装一套19.9的测试库，直接scp一个测试环境的 $ORACLE_HOME过去，改改环境变量，结果起不来sqlplus。
[oracle]host1:/u01/oradata/db_1>oslevel -s
6100-09-06-1543
[oracle]host1:/u01/oradata/db_1>sqlplus /nolog
exec(): 0509-036 Cannot load program sqlplus because of the following errors:
rtld: 0712-001 Symbol __setjmp was referenced

按错误的方法去MOS上搜来搜去，觉得应该把aio或iocp（完成端口）打开，然后就可以了，但是还是不行。之所以这样做是因为别人告诉我这个机器不支持19c，我就想试试看，到底怎么个不支持。
后来看了看认证
最低支持到 aix7.1，就别费劲了。
