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：
