升级过程中由于SCP传输时目标目录/tmp/tempRACTrans_2025_08_22--18-25-44-032/ractrans   不存在导致的OC4J配置失败：

手工去scp文件都能正常传过去，说明问题不在em的安装手法上。后来想到openssh的版本问题，默认版本openssh有漏洞，所以就从7.4p1版本升级到了9.6p1版本，怀疑openssh高版本的兼容性导致，所以进行了重新安装做降级操作。

先对openssl做回退操作：

[root@rac1 ~]# rm /usr/include/openssl
rm: remove symbolic link ‘/usr/include/openssl’? y
[root@rac1 ~]# mv /usr/bin/openssl.bak /usr/bin/openssl
[root@rac1 ~]# openssl version
OpenSSL 1.0.2k-fips  26 Jan 2017

再对openssh做重新初始化安装：

[root@rac1 ~]# yum reinstall openssh openssh-server openssh-clients
[root@rac1 soft]# vi /usr/lib/systemd/system/sshd.service
Type=notify
systemctl daemon-reload
[root@rac1 ~]# systemctl restart sshd
再次创建oem成功：
