删除时报错ORA-15027: active use of diskgroup precludes its dismount ，如下：
SQL> drop diskgroup webdg including contents;
drop diskgroup webdg including contents
*
ERROR at line 1:
ORA-15039: diskgroup not dropped
ORA-15027: active use of diskgroup "WEBDG" precludes its dismount
在删除之前我已经关闭了数据库实例，ASM 实例上还会有什么客户端连接呢？
SQL> select * from v$asm_client;
