Oracle 11g 利用备份复制数据库

测试在同一机器不同数据库实例复制数据库

1.环境

Target DB:

IP:10.131.119.114

HOSTNAME:openstack-node1.example.com

ORACLE_SID:orcl11g

Auxiliary DB:

IP:10.131.119.114

HOSTNAME:openstack-node1.example.com

ORACLE_SID:aux

2.创建Auxiliary DB 参数文件

[[email protected] dbs]$ cat initaux.ora

*.audit_file_dest=‘/u2/oracle/admin/aux/adump‘

*.audit_trail=‘db‘

*.compatible=‘11.2.0.0.0‘

*.control_files=‘/u2/oracle/oradata/aux/control01.ctl‘,‘/u2/oracle/fast_recovery_area/aux/control02.ctl‘

*.db_block_size=8192

*.db_domain=‘us.oracle.com‘

*.db_name=‘aux‘

*.db_recovery_file_dest=‘/u2/oracle/fast_recovery_area‘

*.db_recovery_file_dest_size=4227858432

*.diagnostic_dest=‘/u2/oracle‘

*.dispatchers=‘(PROTOCOL=TCP) (SERVICE=auxXDB)‘

*.log_archive_dest_1=‘location=/u2/oracle/arch/aux‘

*.open_cursors=300

*.pga_aggregate_target=104857600

*.processes=150

*.remote_login_passwordfile=‘EXCLUSIVE‘

*.sga_max_size=272629760

*.sga_target=272629760

*.undo_tablespace=‘UNDOTBS1‘

*.db_file_name_convert=(‘orcl11g‘,‘aux‘)

3.创建Auxiliary DB需要的目录

[[email protected] ~]$ mkdir -p /u2/oracle/admin/aux/adump

[[email protected] ~]$ mkdir -p /u2/oracle/oradata/aux

[[email protected] ~]$ mkdir -p /u2/oracle/fast_recovery_area/aux

[[email protected] ~]$ mkdir -p /u2/oracle/arch/aux

4.创建Auxiliary DB密码文件
[[email protected] dbs]$ cp orapworcl11g orapwaux


5.配置监听与TNS

监听：

[[email protected] admin]$ cat listener.ora

# listener.ora Network Configuration File: /u2/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = orcl11g)

(ORACLE_HOME = /u2/oracle/product/11.2.0/dbhome_1)

(SID_NAME = orcl11g)

)

(SID_DESC =

(GLOBAL_DBNAME = aux)

(ORACLE_HOME = /u2/oracle/product/11.2.0/dbhome_1)

(SID_NAME = aux)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.114)(PORT = 1521))

)

)

ADR_BASE_LISTENER = /u2/oracle


TNS：

[[email protected] admin]$ cat tnsnames.ora

# tnsnames.ora Network Configuration File: /u2/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

ORCL11G =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.114)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl11g)

)

)

aux =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.131.119.114)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = aux)

)

)

6.开始复制操作

[[email protected] ~]$ rman target /     ----连接target DB

Oracle闪回技术之一Oracle 11g 利用FlashTable (闪回表)恢复（用delete）误删的数据

闪回表,实际上就是将表中的数据快速恢复到过去的一个时间点或者系统改变号SCN上.实现表的闪回,需要用到撤销表空间相关的UNDO信息,通过SHOW PARAMETER UNDO命令就可以了解这些信息.用户对表的数据的修改操作,都记录在撤销表空间中,这为表的闪回提供的数据恢复的基础. 修改记录被提交到undo表空间中的默认保留时间为900秒,用户可以在这900秒的时间内对表的进行闪回操作,从而将表中的数据恢复的修改前的状态. 如上图显示的默认900秒,我们通过sql来修改这个默认时间为1200: f
