如果是中文字符集：
[TEST@ora10gr1#2009-11-25/08:39:38]
SQL>create table t1(t timestamp);
Table created.
[TEST@ora10gr1#2009-11-25/08:39:56]
SQL>insert into t1 values(to_timestamp('21NOV09 10:04:12.032','DDMONYY HH24:MI:SS.FF'));
* ERROR at line 1: ORA-01843: not a valid month
应该指定用american字符集插入就对了：
[TEST@ora10gr1#2009-11-25/08:39:56]
SQL>insert into t1 values(to_timestamp('21NOV09 10:04:12.032','DDMONYY HH24:MI:SS.FF','nls_date_language=american'));
1 row created.

/// <summary>
/// 数据库备份
/// </summary>
/// <param name="fileName">dmp文件名称</param>
/// <param name="logFileName">log文件名称</param>
