某某业务数据库RMAN备份实例记录

某某业务数据库RMAN备份实例

1、设置业务数据库日志文件

1.1 修改日志文件

根据本次业务需求，增加一组日志文件，增加成员数为2

日志文件大小修改只能新建后，删除原有旧的文件。

查询在线日志

SQL>select * from v$log;

GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

---------- ---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- --------- ------------ ---------

1 1 151 52428800 5121 NO INACTIVE
168638269 12-JAN-16 168649896 12-JAN-16

2 1 152 52428800 5121 NO CURRENT
168649896 12-JAN-162.8147E+14

3 1 150 52428800 5121 NO INACTIVE
168626218 12-JAN-16 168638269 12-JAN-16

查询日志文件信息

SQL>select * from v$logfile;

GROUP# STATUS TYPE MEMBER IS_

---------- ------- ------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
---

3 ONLINE /opt/oracle/oradata/orcl/redo03.log NO

2 ONLINE /opt/oracle/oradata/orcl/redo02.log NO

1 ONLINE /opt/oracle/oradata/orcl/redo01.log NO

增加文件组4，2个成员

SQL> alter database add logfile group 4 ('/opt/oracle/oradata/orcl/redo41.log','/opt/oradata/orcl/redo42.log') size 256m;

查询日志状态

{CSDN:CODE:

SQL>select * from v$log;

GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

---------- ---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- --------- ------------ ---------

1 1 151 52428800 5121 NO INACTIVE
168638269 12-JAN-16 168649896 12-JAN-16

2 1 152 52428800 5121 NO CURRENT
168649896 12-JAN-162.8147E+14

3 1 150 52428800 5121 NO INACTIVE
168626218 12-JAN-16 168638269 12-JAN-16

}

删除日志组 1 和 3

SQL> alter database drop logfile group 1;

Database altered.

SQL> alter database drop logfile group 3;

Database altered.

注意：Current、Active组不得删除，数据库只有两个组是不得删除，先逻辑删除、后物理删除

增加日志组 1 和 3

SQL> alter database add logfile group 1 ('/opt/oracle/oradata/orcl/redo11.log','/opt/oradata/orcl/redo12.log') size 256m;

Database altered.

SQL> alter database add logfile group 3 ('/opt/oracle/oradata/orcl/redo31.log','/opt/oradata/orcl/redo32.log') size 256m;

Database altered.

查询日志文件信息

{CSDN:CODE:

SQL> select * from v$log;

GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

---------- ---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- --------- ------------ ---------

1 1 0 268435456 5122 YES UNUSED
0 0

2 1 152 52428800 5121 NO CURRENT
168649896 12-JAN-162.8147E+14

3 1 0 268435456 5122 YES UNUSED
0 0

4 1 0 268435456 5122 YES UNUSED
0 0

}

切换日志组

SQL> alter system switch logfile;

System altered.

SQL> select * from v$log;

GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

---------- ---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- --------- ------------ ---------

1 1 153 268435456 5122 NO CURRENT
168655441 12-JAN-162.8147E+14

2 1 152 52428800 5121 NO ACTIVE
168649896 12-JAN-16 168655441 12-JAN-16

3 1 0 268435456 5122 YES UNUSED
0 0

4 1 0 268435456 5122 YES UNUSED
0 0

第二组为ACTIVE组态，强制产生检查点命令

SQL> alter system checkpoint;

System altered.

SQL> select * from v$log;

GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

---------- ---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- --------- ------------ ---------

1 1 153 268435456 5122 NO CURRENT
168655441 12-JAN-162.8147E+14

2 1 152 52428800 5121 NO INACTIVE
168649896 12-JAN-16 168655441 12-JAN-16

3 1 0 268435456 5122 YES UNUSED
0 0

4 1 0 268435456 5122 YES UNUSED
0 0

删除日志组 2

SQL> alter database drop logfile group 2;

Database altered.

增加日志组 2

SQL> alter database add logfile group 2 ('/opt/oracle/oradata/orcl/redo21.log','/opt/oradata/orcl/redo22.log') size 256m;

Database altered.

查询日志组组态

SQL> select * from V$log;

GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME

---------- ---------- ---------- ---------- ---------- ---------- --- ---------------- ------------- --------- ------------ ---------

1 1 153 268435456 5122 NO CURRENT
168655441 12-JAN-162.8147E+14

2 1 0 268435456 5122 YES UNUSED
0 0

3 1 0 268435456 5122 YES UNUSED
0 0

4 1 0 268435456 5122 YES UNUSED
0 0

从磁盘删除以前日志物理文件

$cd /opt/oracle/oradata/orcl/

$rm redo0*.log

2、设置业务数据库归档模式

2.1查询数据库归档模式：

SQL>select log_mode from v$database;

SQL>archive log list (sys用户)

2.2查询参数文件使用方式（spfile）

SQL>show parameter spfile

2.3在spfile工作模式下，设置归档存储路径

SQL> alter system set log_archive_dest_1='location=/opt/oracle/oradata/archive1';

System altered.

SQL> alter system set log_archive_dest_2='location=/opt/oracle/oradata/archive2';

System altered.

设置归档文件存储格式

需要注意，在Oracle 11g中，配置归档日志文件格式时，必须带有%s，%t和%r匹配符

SQL> alter system set log_archive_format='%s_%t_%r.arc' scope=spfile;

System altered.

2.4修改数据库归档模式

SQL>shutdown immediate

SQL>startup mount

SQL>alter database ARCHIVELOG;

SQL>alter database open;

2.5查询归档模式

SQL>select log_mode from v$database;

SQL>archive log list

2.6查询归档存储路径

SQL> show parameter log_archive_dest

3、创建RMAN数据库

创建表空间

SQL>create tablespace rmanspace datafile '/opt/oracle/oradata/orcl/rman01.dbf' size 100m autoextend on next 100m maxsize 8g;

创建用户

SQL>create user rman identified by Zcps_123 default tablespace qhtitle temporary tablespace temp;

更改表空间

SQL>alter user rman default tablespace rmanspace;

授权

SQL>grant connect,resource ,recovery_catalog_owner to rman ;

将密码有效期由默认的180天修改成“无限制”

SQL>ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

4、在业务数据库服务器上关联RMAN数据库

#创建恢复目录

$rman catalog rman/Zcps_123@rmanbackup

RMAN>create catalog;

#连接目标数据库（以后每次都要做，用户必须为sys）

$rman TARGET sys/Qhrsc123 CATALOG rman/Zcps_123@rmanbackup

#注册数据库 （目标控制文件写入rman目录）

RMAN>register database;

RMAN>report schema;

#设置数据保留策略

RMAN>CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 34 DAYS;

RMAN>CONFIGURE CONTROLFILE AUTOBACKUP ON;

RMAN>CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/opt/zcps_backup/hot_backup/autoctl_%F';
