检查oracle服务存在，也启动了；于是就官网查看错误：

ORA-28056: Writing audit records to Windows Event Log failed

Cause: Unable to write an audit entry to the Windows event log used as the audit trail.

Action: Check the error number for a possible operating system error. If there is no error, contact Oracle Support Services.

于是就把系统的“事件查看器”日志清除，Ok，搞定；
