数据库的版本是：
Oracle 19.16
Linux 7.9
解决方法：
查询mos文档：
ORA-00800: soft external error, arguments: [Set Priority Failed], [VKTM] (Doc ID 2718971.1)
使用以下方法解决了：
1) 本身就是0，这一步不需要做
cat /sys/fs/cgroup/cpu,cpuacct/system.slice/cpu.rt_runtime_us
0
# echo 0 > /sys/fs/cgroup/cpu,cpuacct/system.slice/cpu.rt_runtime_us
2) 原来是0，需要修改
cat /sys/fs/cgroup/cpu,cpuacct/user.slice/cpu.rt_runtime_us
0
# echo 950000 > /sys/fs/cgroup/cpu,cpuacct/user.slice/cpu.rt_runtime_us
