SQL> select name from v$datafile;

NAME

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

/dev/rora_system

/dev/rora_undo1

/dev/rora_sysaux

/dev/rora_users

/dev/rora_example

2.建立RMAN所需的表空間，這里采用裸設(shè)備“/dev/rora_backup”

SQL> create tablespace ora_backup datafile'/dev/rora_backup' size 500M;

Tablespace created.

進行查看確認(rèn)

SQL> select name from v$datafile;

NAME

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

/dev/rora_system

/dev/rora_undo1

/dev/rora_sysaux

/dev/rora_users

/dev/rora_example

/dev/rora_backup

6 rows selected.

已經(jīng)發(fā)現(xiàn)ora_backup表空間

3.建立RMAN用戶以及設(shè)定密碼和用戶表空間

SQL> create user rman identified by rman default tablespace ora_backup temporay tablespace temp

2 ;

create user rman identified by rman default tablespace ora_backup temporay tablespace temp

*

ERROR at line 1:

ORA-00922: missing or invalid option

在此處出錯，原來是temporay打錯，繼續(xù)。

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

User created.

呵呵，成功

4.給用戶授權(quán)

SQL> grant connect,resource,recovery_catalog_owner to rman

2 ;

Grant succeeded.

5.連接到數(shù)據(jù)庫

SQL> rman target 'zhirui' catalog rman/rman

SP2-0734: unknown command beginning 'rman targe...' - rest of line ignored.

呵呵，又出錯了，沒退出SQL。

SQL> exit

Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production

With the Partitioning, OLAP and Data Mining options

$ rman target 'zhirui'catalog rman/rman

這下應(yīng)該可以了吧

恩？怎么回事？

RMAN> connect catalog rman/rman

RMAN> exit

Recovery Manager complete.

可以連接呀，再來

$ rman target 'zhirui' catalog rman/rman

target database Password:

connected to target database: ZHIRUI (DBID=1679784276)

connected to recovery catalog database

恩，連接進去了。

6.注冊數(shù)據(jù)庫

RMAN> register database;

7.建立catalog表空間到ora_backup

RMAN> create catalog tablespace ora_backup

recovery catalog created

這下可以注冊了吧。

RMAN> register database;

database registered in recovery catalog

starting full resync of recovery catalog

full resync complete

注冊成功

8.嘗試備份全庫

RMAN> run {

2> allocate channel dev1 type disk;

3> backup

4> format '/home/oracle/data/db_t%t_s%s_p%p'

5> (database);

6> release channel dev1;

7> }

allocated channel: dev1

channel dev1: sid=159 devtype=DISK

Starting backup at 25-MAY-07

channel dev1: starting full datafile backupset

channel dev1: specifying datafile(s) in backupset

input datafile fno=00006 name=/dev/rora_backup

input datafile fno=00001 name=/dev/rora_system

input datafile fno=00003 name=/dev/rora_sysaux

input datafile fno=00005 name=/dev/rora_example

input datafile fno=00002 name=/dev/rora_undo1

input datafile fno=00004 name=/dev/rora_users

channel dev1: starting piece 1 at 25-MAY-07

至此，成功。
