检测数据块损坏(BlockCorruption)

数据块的损坏分两种情况，第一种是物理性的，第二种是逻辑性的。物理性一般指数据块头部不可以访问、数据块校验值不合法。逻辑性一般是在物理性结构完整的情况下，数据的内容在含义上不正确，比如保存了不允许的字段值。

下面分别用两种情况说明数据块的物理错误和数据的逻辑错误

一、数据块物理错误: physical bad block，物理性一般指数据块头部不可以访问、数据块校验值不合法

二、数据逻辑错误：logical bad block，逻辑性一般是在物理性结构完整的情况下，数据的内容在含义上不正确

--创建range分区表
SQL> create table scott.emp1 (empno number(4),ename varchar2(10),deptno number(2)) partition by range (deptno)

三、oracle提供了很多工具用来检查数据块是否损坏，有的可以从物理层面上检查，有的可以从逻辑层面上检测

1.1 DBVERIFY工具，数据块的物理错误可以通过DBV命令检查出来
DBVerify - Identify Datafile Block Corruptions
    DBVERIFY identifiesPhysical and Logical Intra Block Corruptionsby default. Dbverify cannot be run for the whole database in a single command. It does not need a database connection either:

[oracle@wang ~]$ dbv file=/u01/app/oracle/oradata/DBdb/test.dbfblocksize=8192

1.2 RMAN的backup命令
RMAN - Identify Datafile Block Corruptions

To identify both Physical and Logical Block Corruptions use the "CHECK LOGICAL" option. The next command checks the complete database for both corruptionswithout actually doing a backup:
添加check logical选项可以检查逻辑坏块；

$ rman target /
RMAN> backupcheck logicalvalidate

The next command checks the complete database for both corruptions in a backup:

$ rman target /
RMAN> backupcheck logical database

检查坏块,示例：
backup check logical validate datafile 6;
validate check logical datafile 6;

validate database;                                --验证整个数据库
validate backupset 22;                            --验证某个备份文件
validate tablespace users;                        --验证某个表空间
validate datafile 1;                              --验证某个数据文件
validate datafile 1 block 10;                     --验证某个数据文件中的某个块
validate check logical datafile 1 BLOCK 5 TO 20; --检查数据文件 1 中的数据块 5 到 20

backup validate database;                         --验证所有文件，包括数据文件、控制文件、参数文件
backup validate datafile 6;                       --验证6号数据文件
backup validate datafile 4;                       --验证4号数据文件

注意:这个命令只是检查数据库的坏块，而不会真正进行备份。从 11g 开始可以省略 backup 子句，而直接使用命令"validate check logical database"。
如果由于缺失文件导致命令失败，可以增加 'SKIP INACCESSIBLE' 子句来避免这个问题,为了加快检查速度，可以设置 PARALLELISM 指定多个通道:

坏块信息会被记录在视图 V$DATABASE_BLOCK_CORRUPTION 中。使用如上validate 子句检查数据文件等后 RMAN 会生成一个 trace 文件，详细描述坏块信息

或者备份数据文件，也可以检查出坏块。
v$database_block_corruption查看backup操作发现的损坏
V$DATABASE_BLOCK_CORRUPTION displays information about database blocks that were corrupted after the last backup. 此视图只显示上次备份后损坏的数据库块的信息。

参考：http://www.linuxidc.com/Linux/2014-08/105897.htm

1.2.1使用rman备份检查坏块：
[oracle@wang ~]$ rman target /
