客户有个环境需要部署19c，安装的oracle linux 7.9.，OpenSSH_7.4p1版本适合安装19c集群，但接到环境时，发现openssh已升级到9.0了，理由是等保需要，哎，不抱怨自己解决问题

 

 

 

    
[INS-32070] Could not remove the nodes [db2] corresponding to following error code: INS-44000    
    
    
INS-06006 GI RunInstaller Fails If OpenSSH Is Upgraded to 8.x (Doc ID 2555697.1)    
    
Apply patch 30159782 before run "gridSetup.sh", see (Doc ID 1410202.1) for how to apply OneOff patch before run "gridSetup.sh".    

只能降级处理了

将oracle linux 7.9的iso做成yum源
