今日创建新数据库时一直提示，写入audit到Windows

事件日志失败(Writing audit records to Windows Event Log

failed)，一路忽略，算是创建完成。

连接时又出现如下错误：

ERROR:

ORA-28056: 未能将审计记录写入 Windows 事件日志

后来清理了事件查看器(运行 - eventvwr)里的应用程序下的记录(清理前可导出备份)，可以正常登陆了。

外文描述：

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Justified by unpublished Bug.6823281 ORA-28056 WRITING AUDIT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.

其他：

Whenever you see an OS error like that, find the OS-specific

error message. On Windows, the little known command "net helpmsg"

can reduce your guess work:

C:\>net helpmsg 1502

The event log file is full.
