1、 建rman库作为repository
$more createrman_db1.sh
set echo on
spool makedb1.log
create database rman
datafile '/export/home/oracle/oradata/rman_data/system.dbf' size
on next 640K
logfile '/export/home/oracle/oradata/rman_data/redo0101.log' SIZE
'/export/home/oracle/oradata/rman_data/redo0201.log' SIZE
ma
maxinstances 8
maxlogfiles 64
character set US7ASCII
national character set US7ASCII
;
disconnect
spool off
exit
@/export/home/oracle/
REM ********** ALTER SYSTEM TABLESPACE *********
ALTER TABLESPACE SYSTEM
DEFAULT STORAGE ( INITIAL 64K NEXT 64K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCR
EASE 50);
ALTER TABLESPACE SYSTEM
MINIMUM EXTENT 64K;
REM ********** TABLESPACE FOR ROLLBACK **********
CREATE TABLESPACE RBS DATAFILE '/export/home/oracle/oradata/rman_data/rbs.dbf' s
ize
AUTOEXTEND ON NEXT 512K
MINIMUM EXTENT 512K
DEFAULT STORAGE ( INITIAL 512K NEXT 512K MINEXTENTS 10 MAXEXTENTS UNLIMITED PC
TINCREASE 0 );
REM ********** TABLESPACE FOR TEMPORARY **********
CREATE TABLESPACE TEMP DATAFILE '/export/home/oracle/oradata/rman_data/temp.dbf'
size
AUTOEXTEND ON NEXT 64K
MINIMUM EXTENT 64K
DEFAULT STORAGE ( INITIAL 64K NEXT 64K MINEXTENTS 1 MAXEXTENTS UNLIMITED PCTINCR
EASE 0) TEMPORARY;
REM **** Creating four rollback segments ****************
CREATE PUBLIC ROLLBACK SEGMENT RBS_0 TABLESPACE RBS
STORAGE ( OPTIMAL 64000K );
ALTER ROLLBACK SEGMENT "RBS_0" ONLINE;
REM **** SYS and SYSTEM users ****************
alter user sys temporary tablespace TEMP;
alter user system temporary tablespace TEMP;
disconnect
spool off
exit
$more createrman_db3.sh
spool crdb3.log
@/export/home/oracle/
@/export/home/oracle/
@/export/home/oracle/
connect system/manager
@/export/home/oracle/
disconnect
spool off
exit
2、建repository存放的表空间和rman用户
$more createrman_db4.sh
connect internal
create tablespace rman_ts
datafile '/export/home/oracle/oradata/rman_data/rman_ts.dbf'
size
create user rman_hainan identified by rman_hainan
temporary tablespace TEMP
default tablespace rman_ts quota unlimited on
rman_ts;
grant recovery_catalog_owner to rman_hainan;
grant connect ,resource to rman_hainan;
3、建catalog,注册目标数据库
$more createrman_db5.sh
rman catalog rman_hainan/rman_hainan@rman msglog=rman.log
create catalog ;
exit;
rman target sys/oracle@db1
connect catalog rman_hainan/rman_hainan@rman
register database;
exit;
4、可以开始做备份了。
5、做全备
$more rmanshell
. /export/home/oracle/.profile
rman rcvcat rman_hainan/rman_hainan@rman target / cmdfile /export/home/oracle/ba
ckup_level0.rcv log /export/home/oracle/backup.log
$more backup_level0.rcv
resync catalog;
run {
allocate channel t1 type disk;
backup
incremental level 0
skip inaccessible
tag hot_db_bk_level0
filesperset 3
format '/export/home/oracle/bk_%s_%p_%t.bk'
(database);
sql 'alter system archive log current';
backup
filesperset 10
format '/export/home/oracle/a1_%s_%p_%t.ac'
(archivelog all delete input);
backup
format '/export/home/oracle/df_t%t_s%s_p%p.ct'
current controlfile ;
}
6、做增备
$more rmanshell1
rman rcvcat rman_hainan/rman_hainan@rman target / cmdfile backup_level1.rcv log
backup.log
$more backup_level1.rcv
resync catalog;
run {
allocate channel t1 type disk;
backup
incremental level 1
skip inaccessible
tag hot_db_bk_level1
filesperset 3
format 'bk_%s_%p_%t.bk1'
(database);
sql 'alter system archive log current';
backup
filesperset 10
format 'a1_%s_%p_%t.ac1'
(archivelog all delete input);
backup current controlfile;
}
1、 删除旧的全备
$rman rcvcat rman_hainan/rman_hainan@rman target /
Recovery Manager: Release
RMAN-06005: connected to target database: TEST (DBID=1692992254)
RMAN-06008: connected to recovery catalog database
RMAN> list backupset;
RMAN-03022: compiling command: list
List of Backup Sets
Key Recid Stamp
------- ---------- ---------- -- ---------- ---------- ----------------------
38 145 399987408 0 399987406 153 11-JUN-00
根据key来删除旧的备份。
RMAN> allocate channel for maintenance type disk;
RMAN> change backupset 169 delete; ----------THIS IS THE COMMAND TO REMOVE THE ENTRY & OS FILE
做完后可以看到list backupset和操作系统的文件都没有了。
2、 恢复
(1) 将数据库启动到nomount状态:
$svrmgrl
Oracle Server Manager Release
Copyright (c) 1997, 1999, Oracle Corporation. All Rights Reserved.
Oracle8i Enterprise Edition Release
With the Partitioning option
JServer Release
SVRMGR> connect internal
Connected.
SVRMGR> startup nomount;
ORACLE instance started.
Total System Global Area 339275684 bytes
Fixed Size 94116 bytes
Variable Size 318685184 bytes
Database Buffers 16384000 bytes
Redo Buffers 4112384 bytes
SVRMGR> exit
Server Manager complete.
(2) 恢复控制文件:
$rman rcvcat rman_hainan/rman_hainan@rman target /
Recovery Manager: Release
RMAN-06006: connected to target database: test (not mounted)
RMAN-06008: connected to recovery catalog database
RMAN> run {
2> allocate channel d1 type disk;
3> restore controlfile;
4> release channel d1;
5> }
(3) 恢复数据文件
RMAN> run {
2> allocate channel d1 type disk;
3> sql "alter database mount";
4> restore datafile 1;
5> restore datafile 2;
6> restore datafile 3;
7> restore datafile 4;
8> release channel d1;
9> }
(4) 恢复日志文件
RMAN> run {
2> set archivelog destination to '/export/home/oracle/admin/test/arch';
3> allocate channel d1 type disk;
4> restore archivelog all;
5> release channel d1;
6> }
会把所有的日志文件恢复。
(5) 根据日志做recover
$svrmgrl
Oracle Server Manager Release
Copyright (c) 1997, 1999, Oracle Corporation. All Rights Reserved.
Oracle8i
With the Partitioning option
JServer Release
SVRMGR> connect internal
Connected.
