解决过程：

打开windows 事件查看器，将应用程序日志清理一下，重新连接数据库，连接成功。启动数据库，启动正常。

解决这个问题的时候经过了多次的尝试都失败了，开始想到可能是系统日志的问题了，但没想到是日志满了，最后突然想到这个问题，试了一下，成功了。

论坛上有个哥们给了个很好的回复，以下是他的回复：

Subject: Connect As Sysdba Fails With ORA-28056
Doc ID: 784068.1 Type:PROBLEM
Modified Date:20-MAR-2009 Status:MODERATED

Applies to:
Oracle Server - Personal Edition - Version: 11.1.0.6 to 11.1.0.7
This problem can occur on any platform.

Symptoms

connect as sysdba fails with:
ORA-28056: Writing audit records to Windows Event Log failed.

Cause
Event Viewer log is full and not able to log anymore events.

Justified by unpublished Bug.6823281 ORA-28056 WRITING AUDIT RECORDS TO WINDOWS EVENT LOG FAILED

which was closed as not a bug.

Solution
Try doing the following using Event Viewer:
.
To open Event Viewer, click Start, click Control Panel,
click Performance and Maintenance, click Administrative Tools,
and then double-click Event Viewer.
.
You must be logged on as an administrator or a member of the
Administrators group to free an event log.
.
1) When a log is full, it stops recording new events. Clearing the log
is one way to free the log and start recording new events.
.
2) You can also free a log and start recording new events by overwriting
old events. To overwrite events, on the Action menu, click Properties,
and then click Overwrite events as needed. This ensures that all new
events are written to the log, even when the log is full.
.
3) You can also start logging new events by increasing the maximum
log size. To increase the log size, on the Action menu, click Properties,
and then increase the Maximum log size.
