测试使用 Active database duplicate在不同机器不同数据库实例复制数据库
环境:
Target DB:
IP:10.131.119.118
HOSTNAME:CS-SI-DG01
ORACLE_SID:orcl
Auxiliary DB:
IP:10.131.119.119
HOSTNAME:CS-SI-DG02
ORACLE_SID:orclaux
1.将Target DB库的参数文件和密码文件scp到Auxiliary DB库
[[email protected] dbs]$ pwd
/u2/oracle/product/11.2.0/dbhome_1/dbs
[[email protected] dbs]$ scp initorcl.ora 10.131.119.119:/u2/oracle/product/11.2.0/dbhome_1/dbs
[email protected]‘s password:
Permission denied, please try again.
[email protected]‘s password:
stty: standard input: Invalid argument
spfileorcl.ora 100% 3584 3.5KB/s 00:00
[[email protected] dbs]$ scp orapworcl 10.131.119.119:/u2/oracle/product/11.2.0/dbhome_1/dbs
[email protected]‘s password:
stty: standard input: Invalid argument
orapworcl 100% 1536 1.5KB/s 00:00
2.在Auxiliary DB库修改文件名与修改参数文件内容
[[email protected] dbs]$ pwd
/u2/oracle/product/11.2.0/dbhome_1/dbs
[[email protected] dbs]$ mv initorcl.ora initorclaux.ora
[[email protected] dbs]$ mv orapworcl orapworclaux
[[email protected] dbs]$ cat initorclaux.ora
*._undo_autotune=TRUE
*.audit_file_dest=‘/u2/oracle/admin/orclaux/adump‘
*.audit_trail=‘db‘
*.compatible=‘11.2.0.0.0‘
*.control_files=‘/oradata/orclaux/control01.ctl‘,‘/oradata/orclaux/control02.ctl‘#Restore Controlfile
*.db_block_size=8192
*.db_domain=‘‘
*.db_name=‘orclaux‘
*.db_recovery_file_dest=‘/u2/oracle/fast_recovery_area‘
*.db_recovery_file_dest_size=8589934592
*.diagnostic_dest=‘/u2/oracle‘
*.dispatchers=‘(PROTOCOL=TCP) (SERVICE=orclauxXDB)‘
*.job_queue_processes=1000
*.log_archive_dest_1=‘location=/oradata/arch/orclaux‘
*.log_archive_dest_10=‘ ‘
*.memory_max_target=0
*.memory_target=0
*.open_cursors=300
*.pga_aggregate_target=171966464
*.processes=150
*.remote_login_passwordfile=‘EXCLUSIVE‘
*.session_cached_cursors=240
*.sga_target=335544320
*.undo_retention=60
*.undo_tablespace=‘UNDOTBS2‘
*.db_file_name_convert=(‘/oradata/orcl/‘,‘/oradata/orclaux/‘)
*.log_file_name_convert=(‘/oradata/orcl/‘,‘/oradata/orclaux/‘)
3.在Auxiliary DB库建立必要的目录
[[email protected] dbs]$ mkdir -p /u2/oracle/admin/orclaux/adump
[[email protected] dbs]$ mkdir -p /oradata/orclaux/
[[email protected] dbs]$ mkdir -p /oradata/arch/orclaux
4.在Auxiliary DB库启动到nomount状态
[[email protected] orclaux]$ export ORACLE_SID=orclaux
[[email protected] orclaux]$ sqlplus / as sysdba

5.在Auxiliary DB库与Target DB库中配置监听与TNS
Target DB:
[[email protected] admin]$ cat listener.ora --监听配置

)
)
LISTENER =

)
)
[[email protected] admin]$ lsnrctl reload --重新加载监听

5.开始复制数据库
[[email protected] admin]$ export ORACLE_SID=orclaux
[[email protected] admin]$ rman target sys/[email protected] auxiliary sys/[email protected] --连接目标库与辅助库
