ORACLE——一点一点学RMAN备份1

今天开始学习RMAN备份。

本文主要是将关闭的数据库状态修改为开启状态，并对数据库执行全备份。

 

首先打开oracle服务，进入oracle数据库的sql*plus 

[oracle@LabOracle ~]$ sqlplus /nolog

SQL> conn /as sysdba
Connected to an idle instance.
SQL> startup
ORACLE instance started.

 

查看Target Database的归档模式：

SQL> archive log list
Database log mode              No Archive Mode
Automatic archival             Disabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     5
Current log sequence           7

 

目前的数据库处于非归档模式，接下来需要将数据库修改为归档模式

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount  

 

将数据库置于mount状态，在该状态下修改数据库的归档模式：

SQL> alter database archivelog ;

Database altered.

 

将数据库置于Open状态

SQL> alter database open;

Database altered.

 

再次查看数据库的归档模式，此时数据库处于归档模式，

SQL> archive log list;
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     5
Next log sequence to archive   7
Current log sequence 

 

退出SQL*PLUS

SQL> quit

Disconnected from Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options

 

连接到RMAN环境中
[oracle@LabOracle ~]$ rman nocatalog

Recovery Manager: Release 10.2.0.1.0 - Production on ?lh 2? 28 20:38:34 2011

查看是否有备份集

RMAN> list backup; 

 RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of list command at 02/28/2011 20:38:50
RMAN-06171: not connected to target database

 

由于没有连接到目标数据库上，报出上面的错误。连接目标数据库

RMAN> connect target /

connected to target database: ORCL (DBID=1267670310)
using target database control file instead of recovery catalog

 

将数据库进行全备份

RMAN> backup database;

全备份完成后，查看备份集，显示出备份集的内容

RMAN> list backupset;
