实例“PLSExtProc”，状态UNKNOWN

我有我的oracle数据库的问题，我已经搜查/试图加载修复下面的错误，但我无法PLSExtProc的状态更改为READY：实例“PLSExtProc”，状态UNKNOWN

lsnrctl start 
Service "PLSExtProc" has 1 instance(s). 
Instance "PLSExtProc", status UNKNOWN, has 1 handler(s) for this service...

这里有一些信息，可以帮助：

这是完全正常的和预期。 listener.ora的SID_LIST部分中的每个条目都将显示为状态UNKNOWN。这仅仅意味着听众正在为此付诸行动，因为您列出了它。与那些显示READY状态的人对比。这些来自数据库实例本身向监听器注册。把听众当作酒店的前台服务员。 listener.ora的SID_LIST部分是夜间经理向店员递交酒店客人名单。店员无法知道列表的准确性，所以状态是未知的。但是，如果一位客人走过来说“我的名字是鲍勃，如果有人打电话给我，我会在201号房间”，那就是数据库向听众注册。
