oracle linux8.8上安装oracle 19c集群

1、操作系统版本告警

处理办法：export CV_ASSUME_DISTID=RHEL7.6

2、ssh互信故障

查看ssh版本

[root@db1 ~]# ssh -V
OpenSSH_8.0p1, OpenSSL 1.1.1k  FIPS 25 Mar 2021

处理办法-2个节点都需要操作

安装前配置
# mv /usr/bin/scp /usr/bin/scp.orig
# echo "/usr/bin/scp.orig -T \$*" > /usr/bin/scp
# chmod 555 /usr/bin/scp
# cat  /usr/bin/scp
 
安装后还原
mv /usr/bin/scp.orig /usr/bin/scp

3、应用补丁告警
