rhel/centos 8.5下基於asm存儲的oracle 19c安裝

1、參考https://blog.csdn.net/AllanHwang/article/details/127782317爲主體

2、asm磁盤創建參考 https://blog.csdn.net/applmanwx/article/details/120389476，udev配置nvme不生效

3、swapfile一定要大於4GB，2.7GB不夠，否則會在link的時候失敗

4、DBCA創建的時候報錯DBT-05509

解決方法：參考https://forums.oracle.com/ords/apexds/post/dbt-05509-failed-to-connect-to-the-specified-database-labp-2856，LZ是relink後就好了。沒走重啓大法。 

5、解決ORA-00845: MEMORY_TARGET not supported on this system   https://blog.51cto.com/u_9748604/5572702
