标签：辅助 自定义 app orcl 实例 oracle oradata backup u01
文档课题：使用自定义辅助实例执行基于时间点的表空间恢复.
系统：centos 7.9
数据库：oracle 11.2.0.4
1、相关概念
执行TSPITR时，要求表空间必须是自包含.
TSPITR在以下情况使用：
a、恢复因错误的TRUNCATE TABLE而丢失的数据
b、从表逻辑损坏中恢复
c、撤消只影响部分数据库的批作业或DML语句的结果
d、将逻辑方案恢复到与物理数据库其余部分不同的时间点
TSPITR使用可移动表空间和数据泵，提供了以下新功能和特性：
TSPITR可用于恢复已删除的表空间
可反复执行TSPITR恢复到表空间联机之前的多个时间点，而无需使用恢复目录
在Oracle Database 11g发行版2之前，TSPITR 使用导出和导入进行处理.TSPITR现在使用可移动表空间和数据泵.由于底层技术的这一变化，现在可使用TSPITR来恢复已删除的表空间.此外可反复执行TSPITR 恢复到不同的时间点，而无需使用恢复目录.
2、前期准备
2.1、创建表空间和用户
[oracle@leo-11g-ogg ~]$ sqlplus / as sysdba
SYS@orcl> select tablespace_name from dba_tablespaces;
TABLESPACE_NAME
------------------------------
SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
LEO_TS
6 rows selected.
SYS@orcl> create tablespace tsp_acc datafile '/u01/app/oracle/oradata/orcl/tcp_acc01.dbf' size 20m autoextend on;
SYS@orcl> create tablespace tsp_fin datafile '/u01/app/oracle/oradata/orcl/tcp_fin01.dbf' size 20m autoextend on;
SYS@orcl> create user acc identified by acc default tablespace tsp_acc;
SYS@orcl> create user fin identified by fin default tablespace tsp_fin;
SYS@orcl> grant resource,connect to acc;
SYS@orcl> grant resource,connect to fin;
SYS@orcl> select tablespace_name,status from dba_tablespaces;

2.2、备份数据库
RMAN> delete backup;
RMAN> delete copy;
RMAN> run{
2> delete noprompt obsolete;
3> crosscheck backup;
4> delete noprompt expired backup;
5> crosscheck archivelog all;
6> delete noprompt expired archivelog all;
7> backup incremental level=0 database format '/home/oracle/rmanbak/full-%T-%U.bak';
8> backup archivelog all format '/home/oracle/rmanbak/arch-%T-%U.bak';
9> backup current controlfile format '/home/oracle/rmanbak/ctl-%T-%U.bak';
10> backup spfile format '/home/oracle/rmanbak/spf-%T-%U.bak';
11> delete noprompt archivelog all completed before 'SYSDATE-7';
12> }
RMAN retention policy will be applied to the command
RMAN retention policy is set to redundancy 1

2.3、准备测试数据
--在表空间tsp_acc、tsp_fin上创建测试用的数据
[oracle@leo-11g-ogg ~]$ sqlplus acc/acc@orcl
ACC@orcl> create table tb_test(i int);
ACC@orcl> begin
2 for i in 1..1000 loop
3 insert into tb_test(i) values (i);
4 end loop;
5 commit;
6 end;
7 /
ACC@orcl> select count(*) from tb_test;
COUNT(*)
----------
1000
ACC@orcl> conn fin/fin
FIN@orcl> create table tb_lab (i int);
FIN@orcl> begin
2 for i in 1..1000 loop
3 insert into tb_lab (i) values (i);
4 end loop;
5 commit;
6 end;
7 /
FIN@orcl> select count(*) from tb_lab;
COUNT(*)
----------
1000
2.4、恢复时间点
--查询当前数据库时间点.
FIN@orcl> conn / as sysdba
SYS@orcl> select current_scn,to_char(sysdate,'yyyy-mm-dd hh24:mi:ss') from v$database;
CURRENT_SCN TO_CHAR(SYSDATE,'YY
----------- -------------------
3200997 2022-12-23 14:59:37
2.5、删除表
--删除测试表空间tsp_acc上的表tb_test
SYS@orcl> select count(*) from acc.tb_test;
COUNT(*)
----------
1000
SYS@orcl> drop table acc.tb_test;
Table dropped.
SYS@orcl> col owner for a15
SYS@orcl> set line 200
SYS@orcl> select owner,object_name,type,createtime,original_name from dba_recyclebin;
OWNER OBJECT_NAME TYPE CREATETIME ORIGINAL_NAME
---------- ------------------------------ ---------- ------------------- --------------------
ACC BIN$8HpirFNMRpHgU2eFqMCxnQ==$0 TABLE 2022-12-23:14:55:27 TB_TEST
SYS@orcl> commit;
2.6、增加数据
说明：在删除tsp_acc表空间中的tb_test表后，给另一个表空间tsp_fin中的tb_lab表添加数据.若将tsp_acc表空间恢复后，如果tsp_fin表空间上的表数据没丢失的话，则证明基于时间点的表空间恢复只会恢复要操作的表空间.
SYS@orcl> conn fin/fin
FIN@orcl> begin
2 for i in 1001..2000 loop
3 insert into TB_LAB (i) values (i);
4 end loop;
5 commit;
6 end;
7 /
FIN@orcl> select count(*) from tb_lab;
COUNT(*)
----------
2000
说明：准备工作完成.
3、表空间恢复
3.1、创建参数文件
--创建辅助实例的初始化参数文件.
SYS@orcl> show parameter spfile
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /u01/app/oracle/product/11.2.0
/db/dbs/spfileorcl.ora
SYS@orcl> create pfile from spfile;
[oracle@leo-11g-ogg dbs]$ vi initaux.ora
添加如下内容：
*.compatible='11.2.0.4.0'
*.control_files='/u01/app/oracle/oradata/aux/control01.ctl','/u01/app/oracle/fast_recovery_area/aux/control02.ctl'
*.db_block_size=8192
*.db_name=orcl --必须和目标库一样
*.db_unique_name=aux --必须和目标库不一样
*.remote_login_passwordfile='EXCLUSIVE'
*.db_file_name_convert='/u01/app/oracle/oradata/orcl/','/u01/app/oracle/oradata/aux/'
*.log_file_name_convert='/u01/app/oracle/oradata/orcl/','/u01/app/oracle/oradata/aux/','/u01/app/oracle/fast_recovery_area/orcl/','/u01/app/oracle/oradata/aux/','/u01/app/oracle/oradata/ORCL/onlinelog/','/u01/app/oracle/oradata/aux/','/u01/app/oracle/fast_recovery_area/ORCL/','/u01/app/oracle/oradata/aux/'
参数解析：
db_name：必须有,该值须和目标数据库一样.
db_unique_name：必须有, 需和目标库不一样.
compatible：必须有，该值需和目标库一致.
db_block_size：必须有，该值需和目标库一致.
remote_login_passwordfile：必须有，当用一个密码文件连接辅助实例时，该值必须设置成EXCLUSIVE或为NONE.
control_files：非必须参数，该值指定文件名只要不和目标数据库或者其它任意文件名冲突即可.
db_file_name_convert：非必须参数，通过指定该值自动转换路径生成辅助实例所需的数据文件.
log_file_name_convert：非必须参数，该值基于目标数据库的日志文件名，转换路径后生成辅助实例的联机日志文件.
3.2、创建密码文件
创建辅助实例的密码文件.
[oracle@leo-11g-ogg dbs]$ cp orapworcl orapwaux
3.3、创建tns服务名
--创建连接辅助数据库的服务名.
[oracle@leo-11g-ogg admin]$ vi tnsnames.ora
