測試在同一機器不同數據庫實例複製數據庫
1.環境
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.創建Auxiliary DB 參數文件
[oracle@openstack-node1 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.創建Auxiliary DB需要的目錄
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/admin/aux/adump
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/oradata/aux
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/fast_recovery_area/aux
[oracle@openstack-node1 ~]$ mkdir -p /u2/oracle/arch/aux
4.創建Auxiliary DB密碼文件
[oracle@openstack-node1 dbs]$ cp orapworcl11g orapwaux
5.配置監聽與TNS
監聽：
[oracle@openstack-node1 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_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：
[oracle@openstack-node1 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)
)
)
