一、创建恢复目录
创建恢复目录一般分为三大步骤
Step1. 创建存放恢复目录的数据库(或使用已存在的数据库)
Step2. 创建恢复目录的的所有者
Step3. 创建恢复目录
二、创建恢复目录案例
在存储恢复目录的数据库创建表空间用于存储恢复目录schema及恢复目录数据(本文使用已经创建好的数据库catadb来存储恢复目录)
Step1. 创建rman恢复目录表空间
SQL> create tablespace tbs_rman datafile '/data/oracle/odellprod/catadb/tbs_rman01.dbf' size 200m autoextend on;
Tablespace created.
Step2. 创建rman schema
SQL> create user rman identified by rman temporary tablespace temp default tablespace tbs_rman quota unlimited on tbs_rman;
Step3. 角色授予
Step3.1 授予角色
SQL> grant recovery_catalog_owner to rman;
Grant succeeded.
Step3.2 使用rman链接
SQL> conn rman/rman
Connected.
Step3.3 查看privsilge
SQL> select * from session_privs;
PRIVILEGE
----------------------------------------
CREATE SESSION
ALTER SESSION
CREATE TABLE
CREATE CLUSTER
CREATE SYNONYM
CREATE VIEW
CREATE SEQUENCE
CREATE DATABASE LINK
CREATE PROCEDURE
CREATE TRIGGER
CREATE TYPE
11 rows selected.
Step3.4 查看roles
SQL> select * from session_roles;
ROLE
------------------------------
RECOVERY_CATALOG_OWNER
Step4. 连接到恢复目录
RMAN> connect catalog rman/rman@catadb
connected to recovery catalog database
Step5. 创建恢复目录
RMAN> create catalog tablespace tbs_rman;
recovery catalog created
[oracle@odellprod ~]$ rman target sys/oracle@odellprod catalog rman/rman@catadb --连接到目标数据库及恢复目录
connected to target database: ORCL (DBID=1260850162)
connected to recovery catalog database
Step6. 将目标数据库注册到恢复目录
RMAN> register database;
database registered in recovery catalog
starting full resync of recovery catalog
full resync complete
三、基于恢复目录的备份
1.查看相关信息
RMAN> list incarnation; --列出备份
RMAN> crosscheck copy; --校验copy
RMAN> delete expired copy; --删除过期的copy
2.全备
RMAN> run{
allocate channel ch1 device type disk;
backup as compressed backupset
database plus archivelog delete input
format='/u01/app/oracle/bk/rmbk/Whole_%d_%U'
tag='whole_bak';
release channel ch1;}
3.增量备份(0级)
RMAN> run{
allocate channel ch1 device type disk;
allocate channel ch2 device type disk;
backup as compressed backupset
incremental level 0
database plus archivelog delete input
format='/u01/app/oracle/bk/rmbk/Inc_0_%d_%U'
tag='inc_0';
release channel ch1;
release channel ch2;}
RMAN> list backup summary;
4.增量备份(1级)
RMAN> run{
allocate channel ch1 device type disk;
allocate channel ch2 device type disk;
backup as compressed backupset
incremental level 1 database
format='/u01/app/oracle/bk/rmbk/Inc_1_%d_%U'
tag='inc_1';
release channel ch1;
release channel ch2;}
RMAN> list backup by file;
5.累计增量备份(1级)
RMAN> run{
allocate channel ch1 device type disk;
backup as compressed backupset
incremental level 1 cumulative database
format '/u01/app/oracle/bk/rmbk/Cum_1_%d_%U'
tag='cum_1';
release channel ch1;}
6.备份表空间
RMAN> run{
allocate channel ch1 device type disk;
backup as compressed backupset
tablespace users,example
format='/u01/app/oracle/bk/rmbk/tbs_%d_%U'
tag='tbs';
RMAN> list backupset tag=tbs;
7.备份数据文件
RMAN> run{
allocate channel ch1 device type disk;
backup as compressed backupset
datafile 3
format='/u01/app/oracle/bk/rmbk/df_%d_%U'
tag='df';
release channel ch1;}
8.备份归档日志
备份归档日志前，建议先使用crosscheck校验一下
crosscheck通常用于检查备份是否被删除，如果删除将会打上删除标签
RMAN> crosscheck archivelog all;
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=148 devtype=DISK
validation succeeded for archived log
archive log filename=/u01/app/oracle/oradata/orcl/arch/log_1_117_733069427.arc recid=111 stamp=733171369
crosschecked 1 objects
RMAN> sql 'alter system switch logfile';
RMAN> sql 'alter system switch logfile';
RMAN> list archivelog all;
9.基于SCN来备份归档日志
RMAN> run{
allocate channel ch1 device type disk;
backup as compressed backupset
archivelog from scn 848043
format='/u01/app/oracle/bk/rmbk/arc_%d_%U'
tag='arc';
release channel ch1;}
10.镜像备份
RMAN> run{
allocate channel ch1 device type disk;
backup as copy datafile 1,4
format '/u01/app/oracle/bk/rmbk/df_%d_%U'
tag 'copybak';
release channel ch1;}
11.其它
RMAN> crosscheck backupset;
RMAN> change backupset 1
RMAN> validate backupset
RMAN> validate backupset 635;
