简介： 主要由:message.jspMessageFormMessageActionPlayer.hbm.xmlstruts-config.xmlMeisaiBean.

主要由:
message.jsp
MessageForm
MessageAction
Player.hbm.xml
struts-config.xml
MeisaiBean.java
来实现:
先看数据库结构:
CREATE TABLE player

  displayName  VARCHAR(100),

  MIDDLE_NAME VARCHAR(100),
  STATUS      VARCHAR(32),
  POS         VARCHAR(1),
  PPG         INTEGER default 25
);

oracle数据恢复—Oracle数据库文件大小变为0kb的数据恢复案例
存储掉盘超过上限，lun无法识别。管理员重组存储的位图信息并导出lun，发现linux操作系统上部署的oracle数据库中有上百个数据文件的大小变为0kb。数据库的大小缩水了80%以上。 取出&并分析oracle数据库的控制文件。重组存储位图信息，重新导出控制文件中记录的数据文件，发现这些文件的大小依然为0kb。

服务器数据恢复—华为S5300存储Oracle数据库恢复案例
服务器存储数据恢复环境： 华为S5300存储中有12块FC硬盘，其中11块硬盘作为数据盘组建了一组RAID5阵列，剩下的1块硬盘作为热备盘使用。基于RAID的LUN分配给linux操作系统使用，存放的数据主要是Oracle数据库。 服务器存储故障： RAID5阵列中1块硬盘出现故障离线，热备盘自动激活开始同步数据，在同步数据的过程中又一块硬盘离线，RAID5阵列瘫痪，上层LUN无法使用。
