frm和ibd文件数据库恢复

这次客户rm -rf /var/lib/mysql删除文件,删除一半及时终止,但是已经有很多mysql相关文件被删除,重要的ibdata文件已经被删除,并且客户尝试了大量的恢复工作,对该分区进行了大量的写入操作,导致后面通过对xfs文件系统进行分析，确认无法恢复对应的ibdata文件.比较幸运客户需要的核心的mysql库都还在(frm和ibd文件还存在)

对于这种情况,可以参考以前类似的处理方法:[MySQL异常恢复]mysql ibd文件恢复
由于客户无法提供创建表语句需要通过对frm进行解析获取语句,利用mysqlfrm获取表创建语句

E:\3>mysqlfrm --server=root:oracle@192.168.222.79:3306 --diagnostic T_XIFENFEI.frm
WARNING: Using a password on the command line interface can be insecure.
# Source on 192.168.222.79: ... connected.
# CAUTION: The diagnostic mode is a best-effort parse of the .frm file. As such, it may not identify all of 
  the components of the table correctly. This is especially true for damaged files. 
  It will also not read the default values for the columns and the resulting statement may not be syntactically correct.
# Reading .frm file for EVALUATOR_T.frm:
# The .frm file is a TABLE.
# CREATE TABLE Statement:

CREATE TABLE `T_XIFENFEI` (
  `ID` varchar(32) COLLATE `utf8_general_ci` DEFAULT NULL comment '主键',
  `BO_TYPE_DEFINE_ID` varchar(32) COLLATE `utf8_general_ci` DEFAULT NULL comment '业务对象类型ID',
  `MAIN_ID` varchar(32) COLLATE `utf8_general_ci` DEFAULT NULL comment '业务对象主表记录ID',
  `PARENT_ID` varchar(32) COLLATE `utf8_general_ci` DEFAULT NULL comment '父ID',
  `ROW_NUM` decimal(32,0) DEFAULT NULL comment '行号',
  `VERSION` decimal(32,6) DEFAULT NULL comment '版本',

  `UPDATE_DATE` datetime DEFAULT NULL comment '更新时间',
  `BO_SOURCE_ROW_ID` varchar(32) COLLATE `utf8_general_ci` DEFAULT NULL comment '来源明细行ID',
  `EVALUATORS` text COLLATE `utf8_general_ci` DEFAULT NULL,
  `IMPORTANCE` decimal(32,6) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8, COMMENT '评分人';
#...done.

对于有些获取语句失败,比如类似这样错误

E:\TEMP\10000246_1108\db\ync2_fssc_2000003>mysqlfrm --server=root:oracle@192.168.222.79:3306 --diagnostic T_XFF.frm
Traceback (most recent call last):
  File "G:\ade\build\Python-2.7.6-windows-x86-64bit\lib\site-packages\cx_Freeze\initscripts\Console.py",

IndexError: list index out of range

使用专门的工具对其进行解析

然后利用这些创建表语句在库中创建表,并利用以下方法进行操作

mysql> alter table  `t_xifenfei` discard tablespace;        
Query OK, 0 rows affected (0.00 sec)

--上传老的t_xifenfei.ibd文件,并修改所有者和属组

mysql> alter table  `t_xifenfei` import tablespace;                
Query OK, 0 rows affected, 2 warnings (0.01 sec)

mysql> select count(1) from   `t_xifenfei` ;              
+----------+
| count(1) |
+----------+
|       78 |
+----------+
1 row in set (0.00 sec)

使用类似的方法对于数据进行批量处理,然后使用mysqldump进行导出.在这个ibd的discard和import的过程中,有些异常情况这三种错误的处理

mysql> alter table T_LOG_XIFENFEI                   import tablespace;
ERROR 1808 (HY000): Schema mismatch (Table has ROW_TYPE_DYNAMIC row format, .ibd file has ROW_TYPE_COMPACT row format.)
mysql> alter table     `T_LOG_XIFENFEI` import tablespace;
ERROR 1817 (HY000): Index corrupt: Externally stored column(4) has a reference length of 4 in the cluster index PRIMARY
mysql> alter table       `T_LOG_XIFENFEI` import tablespace;
ERROR 1815 (HY000): Internal error: Cannot reset LSNs in table `XFF`.`T_LOG_XIFENFEI` : Data structure corruption

Schema mismatch (Table has ROW_TYPE_DYNAMIC row format, .ibd file has ROW_TYPE_COMPACT row format.) 这种错误是由于row_format设置不正确导致,重新创建表使用正确的row_format然后执行discard和import操作.
Index corrupt: Externally stored column(4) has a reference length of 4 in the cluster index PRIMARY 这种错误是由于表的创建语句和ibd中记录数据不匹配,主要是由于创建表语句不完全正确导致,重新获取正确语句进行恢复
Internal error: Cannot reset LSNs in table `XFF`.`T_LOG_XIFENFEI` : Data structure corruption 这种错误是由于ibd文件本身不一致无法使用该方法恢复,对于这类情况使用我们专业的工具进行处理

标题：impdp TRANSFORM参数

在impdp的参数中有一个transform参数,用来实现在创建对象的时候对一些存储参数进行修改,官方关于这个参数说明:

TRANSFORM
要应用于适用对象的元数据转换。
有效的关键字为: OID, PCTSPACE, SEGMENT_ATTRIBUTES 和 STORAGE。

对主要的SEGMENT_ATTRIBUTES和STORAGE参数进行测试

SQL> create user xff identified by oracle default tablespace users;

用户已创建。

SQL> grant dba to xff;

授权成功。

SQL> create table xff.t_1 as select * from dba_objects;

表已创建。

确认block 135708 有问题,确认起对象为I_OBJ5

这个对象为核心对象obj$的index,无法直接rebuild,当然可以通过参考以前blog文档进行重建:bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决,直接对该坏块进行修复.
