OS 版本一样；
Oracle 版本必须一样，同时安装目录结构建议做成一样，以免发生不必要的错误；
开始安装oracle时，在primary 和 standby 上都装上instance, 要求安装的 SID都必须一样。
shutdown冷备.
将primary和standby都置为archive log 状态：
Startup mount
alter database archivelog;
alter system archive log start
分别修改primary和standby 库的配置文件。
两数据库的配置：
配置priamry listener.ora
# LISTENER.ORA Network Configuration File: d:\oracle\ora92\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.219)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\ora92)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = epg)
(ORACLE_HOME = D:\oracle\ora92)
(SID_NAME = gdepg)
)
)
配置从standby listner.ora 文件：
# LISTENER.ORA Network Configuration File: d:\oracle\ora92\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.218)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\ora92)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = epg)
(ORACLE_HOME = D:\oracle\ora92)
(SID_NAME = gdepg)
)
)
配置主primary 的tnsnames.ora
（必须保证这里面只有两项，primary和standby的两个。同时建议用 “Net Manager” 来操作自动产生配置文件。否则会发生莫名其妙的问题。）
# TNSNAMES.ORA Network Configuration File: d:\oracle\ora92\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
STANDBY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.218)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = gdepg)
)
)
PRIMARY =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.219)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = gdepg)
)
)
配置从standby listner.ora 文件：
# LISTENER.ORA Network Configuration File: d:\oracle\ora92\network\admin\listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.72.218)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\ora92)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = epg)
(ORACLE_HOME = D:\oracle\ora92)
(SID_NAME = gdepg)
)
)
