RMAN>
1.创建辅助实例的口令文件
$ export ORACLE_SID=sztech2
$ orapwd file=$ORACLE_HOME/dbs/orapwsztech2
2.建立到辅助实例的连接
vi $ORACLE_HOME/network/admin/tnsnames.ora
sztech2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.50)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = sztech2)
)
)
建立辅助实例的静态监听.
vi $ORACLE_HOME/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_NAME =sztech2
(ORACLE_HOME = /oracle/app/oracle/product/11.2.0.3/db_1)
(SID_NAME = sztech2)
)
)
重起监听,让新的辅助实例监听生效
$ lsnrctl stop
$ lsnrctl start
$ lsnrctl status
测试一下连接到辅助实例
$ tnsping sztech2
3.建立初始参数
3.1 从源库产生一个文本型的初始参数
$ export ORACLE_SID=sztech1
$ sqlplus /nolog
sql>conn / as sysdba
sql>create pfile='/home/oracle/initsztech2.ora' from spfile;
3.2 修改产生的初始参数(根据需要)
修改后为:
*.audit_file_dest='/oracle/app/oracle/admin/sztech2/adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.c,'/oracle/app/oracle/fast_recovery_area/sztech2/control02.ctl'
*.db_block_size=8192
*.db_domain=''
*.db_name='sztech2'
*.db_recovery_file_dest='/oracle/app/oracle/fast_recovery_area'
*.db_recovery_file_dest_size=4322230272
*.diagnostic_dest='/oracle/app/oracle'
*.job_queue_processes=1000
*.memory_target=320756992
*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.resource_manager_plan='APPUSER_PLAN'
sztech2.resource_manager_plan='APPUSER_PLAN'
*.undo_tablespace='UNDOTBS1'
db_file_name_c,'/oracle/app/oracle/oradata/sztech2'
log_file_name_c,'/oracle/app/oracle/oradata/sztech2'
3.3 根据参数,建立相应的目录
$ cp -R /oracle/app/oracle/admin/sztech1 /oracle/app/oracle/admin/sztech2
$ mkdir /oracle/app/oracle/fast_recovery_area/sztech2
$ mkdir /oracle/app/oracle/oradata/sztech2
4. 启动辅助数据库到nomount
$ export ORACLE_SID=sztech2
$ sqlplus /nolog
sql> conn / as sysdba;
sql> startup nomount pfile=/home/oracle/initsztech2.ora;
创建服务参数文件
sql> create spfile from pfile='/home/oracle/initsztech2.ora';
使用新的服务参数文件启动数据库到nomount
sql> shutdown immediate
sql> startup nomount;
5.打开源库
6.确定源库的数据文件备份和归档日志文件备份能够被辅助实例访问.
7. 使用rman 连接到源库和辅助库
$ rman target sys/oracle auxiliary sys/oracle@sztech2
8.执行复制
必须开启一个到辅助数据库的连接通道channel
rman >
run{
allocate auxiliary channel aux1 device type disk;
duplicate target database to sztech2;
}
执行...
此处省略 ...
一直到 Finished Duplicate Db at 29-JUL-12

建立辅助实例的静态监听.
vi $ORACLE_HOME/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_NAME =sztech2
(ORACLE_HOME = /oracle/app/oracle/product/11.2.0.3/db_1)
(SID_NAME = sztech2)
)
)
重起监听,让新的辅助实例监听生效
$ lsnrctl stop
$ lsnrctl start
$ lsnrctl status
测试一下连接到辅助实例
$ tnsping sztech2
3.建立初始参数
3.1 从源库产生一个文本型的初始参数
$ export ORACLE_SID=sztech1
$ sqlplus /nolog
sql>conn / as sysdba
sql>create pfile='/home/oracle/initsztech2.ora' from spfile;
3.2 修改产生的初始参数(根据需要)
修改后为:
*.audit_file_dest='/oracle/app/oracle/admin/sztech2/adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.c,'/oracle/app/oracle/fast_recovery_area/sztech2/control02.ctl'
*.db_block_size=8192
*.db_domain=''
*.db_name='sztech2'
*.db_recovery_file_dest='/oracle/app/oracle/fast_recovery_area'
*.db_recovery_file_dest_size=4322230272
*.diagnostic_dest='/oracle/app/oracle'
*.job_queue_processes=1000
*.memory_target=320756992
*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.resource_manager_plan='APPUSER_PLAN'
sztech2.resource_manager_plan='APPUSER_PLAN'
*.undo_tablespace='UNDOTBS1'
db_file_name_c,'/oracle/app/oracle/oradata/sztech2'
log_file_name_c,'/oracle/app/oracle/oradata/sztech2'
3.3 根据参数,建立相应的目录
$ cp -R /oracle/app/oracle/admin/sztech1 /oracle/app/oracle/admin/sztech2
$ mkdir /oracle/app/oracle/fast_recovery_area/sztech2
$ mkdir /oracle/app/oracle/oradata/sztech2
4. 启动辅助数据库到nomount
$ export ORACLE_SID=sztech2
$ sqlplus /nolog
sql> conn / as sysdba;
sql> startup nomount pfile=/home/oracle/initsztech2.ora;
创建服务参数文件
sql> create spfile from pfile='/home/oracle/initsztech2.ora';
使用新的服务参数文件启动数据库到nomount
sql> shutdown immediate
sql> startup nomount;
5.打开源库
6.确定源库的数据文件备份和归档日志文件备份能够被辅助实例访问.
7. 使用rman 连接到源库和辅助库
$ rman target sys/oracle auxiliary sys/oracle@sztech2
8.执行复制
必须开启一个到辅助数据库的连接通道channel
rman >
run{
allocate auxiliary channel aux1 device type disk;
duplicate target database to sztech2;
}
执行...
此处省略 ...
一直到 Finished Duplicate Db at 29-JUL-12
具体日志,见第一楼.
说明:
源库:sztech1
辅助库:sztech2
