现象：
sql> shutdown immediate ORA-24324: service handle not initialized ORA-24323: value not allowed ORA-01089: immediate shutdown in progress - no operations are permitted
可能关闭的时候出现问题了，查看了一下系统进程，Oracle的进程还在
ps -ef | grep oratest

解决方法：先 shutdown abort ，再 startup ，或者 start force.
如果shutdown abort也报错：
sql> shutdown abort
ORA-01031: insufficient privileges
可以多等一会儿再试
