创建测试表空间：
SQL> create tablespace tablespace1
2 datafile '/db/app/oracle/oradata/orcl/tablespace1.dbf' 3 size 10m; Tablespace created. SQL>
创建测试用户并指定为默认表空间：
SQL> create user user1 identified by oracle default tablespace tablespace1; User created. SQL>
设置该测试用户权限：
SQL> grant create session,create table,unlimited tablespace to user1; Grant succeeded. SQL>
用新创建的用户登录： SQL> conn user1/ Enter password: Connected. SQL>
建表并写入数据：
SQL> create table table1 (id int,name varchar2(30)); Table created.
SQL> insert into table1 values(0001,'Tian'); 1 row created.
SQL> insert into table1 values(0002,'zhong'); 1 row created.
SQL> select * from table1; ID NAME

配置RMAN环境变量
切换sys用户作0级备份：
利用configure命令配置RMAN环境:
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON; #开启归档日志自动备份 RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/db/bak/ctf/%d_ctf_bak_%F'; #指定归档日志备份位置
RMAN> CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO COMPRESSED BACKUPSET; #采用并行度为2且压缩备份集的方式备份到磁盘。
RMAN> CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT '/db/bak/disk1/%d_datafile_bak_%U'; RMAN> CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT '/db/bak/disk2/%d_datafile_bak_%U';
RMAN> show all;
RMAN configuration parameters for database with db_unique_name ORCL are: CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default CONFIGURE BACKUP OPTIMIZATION OFF; # default CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/db/bak/ctf/%d_ctf_bak_%F'; CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO COMPRESSED BACKUPSET; CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default CONFIGURE CHANNEL DEVICE TYPE DISK MAXPIECESIZE 2 G;
CONFIGURE CHANNEL 1 DEVICE TYPE DISK FORMAT '/db/bak/disk1/%d_datafile_bak_%U'; CONFIGURE CHANNEL 2 DEVICE TYPE DISK FORMAT '/db/bak/disk2/%d_datafile_bak_%U'; CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/db/app/oracle/product/11.2.0/dbhome_1/dbs/snapcf_orcl.f'; # default
备份全库（包括归档日志及启动参数文件等）： RMAN>
RMAN> backup incremental level 0 database plus archivelog;

SQL> insert into table1 values(3,'wang'); 1 row created.
SQL> insert into table1 values(4,'newtest'); 1 row created.
SQL> select * from table1; ID NAME
---------- ------------------------------ 1 Tian 2 zhong 3 wang 4 newtest SQL> commit;
Commit complete.插入成功，并提交。
1级增量备份全库：
RMAN> backup incremental level 1 database plus archivelog; … …
省略备份过程细节。
提示备份成功。可以再通过RMAN> list backup；查看已有备份确认（此时LV字段包含0和1，表示目前备份中已包含有0级和1级增量备份）。
接下来开始恢复：
