问题描述：业务部门在10月26日发现某张基础表中丢失部分数据，系为9月份录入系统的基础数据丢失

Oracle RAC环境做的RMAN备份，10月18日做过expdp数据泵备份，丢失数据表名为T_GL_BALANCE，初始化表t_gl_balance_inibak

1. 查询数据操作记录

SQL>select t.SQL_TEXT, t.FIRST_LOAD_TIME from v$sqlarea t where t.FIRST_LOAD_TIME like ‘2019-10-%‘ order by t.FIRST_LOAD_TIME desc;

过滤出对T_GL_BALANCE数据表删除操作记录如下：

DELETE FROM T_GL_BALANCE WHERE (((FYEAR = :FNEXTYEAR AND FPERIOD = :FNEXTPERIOD) AND FACCOUNTBOOKID = :FACCOUNTBOOKID) AND FADJUSTPERIOD = 0) 2019-10-26/11:10:48

推断数据丢失发生在10月25、26日这两天

2. expdp数据泵备份还原至测试库

impdp user/passwd@localhost:1521/kdtest directory=dump dumpfile=dump191018.dump logfile=dump191018.log

3. 将T_GL_BALANCE表测试库导出，然后导入至正式库

测试库导出

expdp user/passwd@localhost:1521/kdtest tables=t_gl_balance_inibak directory=dump dumpfile=dump19102801.dump logfile=dump19102801.log

正式库导入

impdp user/passwd@scan-ip:1521/实例名 directory=dump dumpfile=dump19102801.dump logfile=dump19102801.log remap_table=t_gl_balance_inibak:tmp_t_gl_balance_inibak cluster=n;

remap_table设置表名重命名，以下为拷贝参数设置介绍：

REMAP_DATA 指定数据转换函数,例如REMAP_DATA=EMP.EMPNO:REMAPPKG.EMPNO REMAP_DATAFILE 在所有DDL语句中重新定义数据文件引用。

REMAP_SCHEMA 将一个方案中的对象加载到另一个方案。

REMAP_TABLE 表名重新映射到另一个表,例如 REMAP_TABLE=EMP.EMPNO:REMAPPKG.EMPNO。

REMAP_TABLESPACE 将表空间对象重新映射到另一个表空间。

REUSE_DATAFILES 如果表空间已存在, 则将其初始化 (N)。

REMAP_SCHEMA参数

众所周知：IMP工具的FROMUSER和TOUSER参数可以实现将一个用户的的数据迁移到另外一个用户。 　　

impdp数据泵使用REMAP_SCHEMA参数来实现不同用户之间的数据迁移； 　　

语法： 　　

　　 REMAP_SCHEMA=source_schema:target_schema 　　

　　 impdp orcldev/oracle DIRECTORY=backup_path DUMPFILE=oracldev.dmp REMAP_SCHEMA=orcldev:orcltwo 　　

与REMAP_SCHEMA类似的参数选项，如REMAP_TABLESPACE将源表空间的所有对象导入目标表空间。

REMAP_TABLE参数

将源表数据映射到不同的目标表中 　　

　　impdp orcldev/oracle DIRECTORY=backup_path dumpfile=oracldev.dmp remap_table=TAB_TEST:TEST_TB 　　

数据导入到TEST_TB表中，但是该表的索引等信息并没有相应的创建，需要手工初始化。

REMAP_DATAFILE参数

语法：REMAP_DATAFILE=source_datafile:target_datafile 　　

Oracle_Online: 　　

　　Remapping datafiles is useful when you move databases between platforms that have different file naming conventions. The source_datafile and target_datafile names should be exactly as you want them to appear in the SQL statements where they are referenced. Oracle recommends that you enclose datafile names in quotation marks to eliminate ambiguity on platforms for which a colon is a valid file specification character.

4. 查找丢失数据，导入正式库表T_GL_BALANCE中

SQL> alter table tmp_t_gl_balance_inibak drop column FYEARPERIOD;　　　　　　　　　　　　　　　--删除自动生成的唯一字段

SQL> insert into t_gl_balance select * from tmp_t_gl_balance_inibak where faccountbookid=151508;　　  --插入查询结果时少字段

SQL> alter table tmp_t_gl_balance_inibak add FYEARPERIOD NUMBER;　　　                                        --将删除字段加回来

SQL> insert into t_gl_balance select * from tmp_t_gl_balance_inibak where faccountbookid=151508;         --插入查询结果时报错

ORA-11523: Message 11523 not found;  product=RDBMS; facility=ORA   google没有找到对应报错

直接在数据库服务器上操作：

sqlplus user/passwd@scan-ip/实例名

SQL> insert into t_gl_balance select * from tmp_t_gl_balance_inibak where faccountbookid=151508;

ORA-54013: INSERT operation disallowed on virtual columns　　报错已经很明显了，通过指定列名来进行插入

SQL> insert into t_gl_balance(FACCOUNTBOOKID,FYEAR,FPERIOD,FACCOUNTID,FDETAILID,FCURRENCYID,FBEGINBALANCEFOR,FBEGINBALANCE,FDEBITFOR,FDEBIT,FCREDITFOR,FCREDIT,FYTDDEBITFOR,FYTDDEBIT,FYTDCREDITFOR,FYTDCREDIT,FENDBALANCEFOR,FENDBALANCE,FADJUSTPERIOD) select FACCOUNTBOOKID,FYEAR,FPERIOD,FACCOUNTID,FDETAILID,FCURRENCYID,FBEGINBALANCEFOR,FBEGINBALANCE,FDEBITFOR,FDEBIT,FCREDITFOR,FCREDIT,FYTDDEBITFOR,FYTDDEBIT,FYTDCREDITFOR,FYTDCREDIT,FENDBALANCEFOR,FENDBALANCE,FADJUSTPERIOD from tmp_t_gl_balance_inibak where faccountbookid=151508;

插入成功，将其他丢失数据批量恢复

5. 问题原因及问题出现的操作和时间节点

原因：业务系统BUG，反过账操作会将前一期数据清除

SQL>select  to_char(FDATETIME,‘YYYY-MM-DD HH24:mi:ss‘),FDESCRIPTION,FCLIENTIP  from t_bas_operatelog where fdescription like  ‘%过账%‘ and to_char(FDATETIME,‘YYYY-MM-DD‘) in (‘2019-10-25‘,‘2019-10-26‘);

SQL>select  to_char(FDATETIME,‘YYYY-MM-DD HH24:mi:ss‘),FDESCRIPTION,FCLIENTIP  from t_bas_operatelogbk where fdescription like  ‘%过账%‘ and to_char(FDATETIME,‘YYYY-MM-DD‘) in (‘2019-10-25‘,‘2019-10-26‘);

通过日志追溯到了时间及具体操作等，接下来就是让业务系统厂家打补丁了。
