SQL> conn / as sysdba
Connected to an idle instance.
SQL> shutdown immediate
ORA-24324: service handle not initialized
ORA-24323: value not allowed
ORA-01089: immediate shutdown in progress - no operations are permitted
SQL> shutdown immediate

网上找了半天说直接shutdown abort就好了，但是我执行shutdown abort时出现下列错误
SQL> shutdown abort
ORA-01031: insufficient privileges
最终解决方法：
在root下vi /etc/host
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
删除上面红色一行，然后重新进入oracle用户，进sqlplus 执行
shutdown abot 可行
SQL> shutdown abort
ORACLE instance shut down.
有可能也许不是上面红色那句话的原因，也需exit出去，然后重新进入oracle用户就好了，不明白，反正就这样稀里糊涂的就解决了
非常诡异的错误，不知为什么？
