1.环境说明
vbox 准备两个虚拟机，Linux 环境 OracleLinux x86.64-dvd，一个虚拟机已经搭建好库，一个虚拟机装好数据库软件，两个虚拟机要能相互ping 通，实例名都是orcl(实例名区分大小写)。
主库数据库版本

7 rows selected.5 在主备库分别创建 Listener 并配置静态注册
使用 netca 命令创建监听，netmgr 命令配置静态注册
--主库192.168.56.67监听
[oracle@localhost admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle--备库192.168.56.68监听
[oracle@localhost admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME = orcl)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracleSID_LIST_LISTENER 部分的内容就是静态注册，如果没有该参数，而且 Data Guard 启动顺序又不正确，
那么在 主库可能会报 PING[ARC1]: Heartbeat failed to connect to standby 'orcl_st'. Error is 12512. 错误，导致归档无法完成。
6 在主备库添加 Oracle Net Service
特别说明一下在备库没有安装数据库的时候/u01/app/oracle/product/11.2.0/db_1/network/admin 目录下没有tnsnames.ora 文件
此时需要手工建netmgr 创建
--在主备库添加一下内容
[oracle@localhost admin]$ ls
listener1704192PM0644.bak samples tnsnames1704192PM0644.bak
listener.ora shrept.lst tnsnames.ora
ORCL_PD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.67)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)
ORCL_ST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.68)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
) [oracle@localhost admin]$ cat tnsnames.ora

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
ORCL_PD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.67)(PORT = 1521))
)
(CONNECT_DATA =

)
)
ORCL_ST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.68)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
) 配置完成后，使用 tnsping 命令效验：
[oracle@localhost admin]$ tnsping orcl_pd

7 在备库创建相关的目录
因为我们的备库没有创建实例，所以是没有相关的目录的，我们需要参考主库的位置来创建。
[oracle@localhost oracle]$ pwd /u01/app/oracle [oracle@localhost oracle]$ ls admin checkpoints fast_recovery_area product cfgtoollogs diag oradata
--FRA目录
[oracle@localhost orcl]$ pwd
/u01/app/oracle/fast_recovery_area/orcl--DATAFILE
[oracle@localhost orcl]$ pwd
/u01/app/oracle/oradata/orcl
[oracle@localhost orcl]$ pwd
/u01/app/oracle/admin/orcl8 在主库创建 pfile 文件并修改 pfile 内容

*.db_file_name_convert='/u01/app/oracle/oradata/orcl','/u01/app/oracle/oradata/orcl'--注意这 2 个参数。这个 2 个参数，只在数据库为 standby_role 时才生效，但我们在主库还是配置这 2 个参数，
就是为了减少以后做 switchover 的时间。 注意 2 个目录的结构。 前面是发送数据的，后面的接收数据的。
用pfile启动主库，并创建spfile

[oracle@localhost orcl]$ pwd
/u01/app/oracle/admin/orcl
[oracle@localhost orcl]$ mkdir adump 建好目录adump 在启动就没问题了,原因是因为 参数文件里有 audit_file_dest='/u01/app/oracle/admin/orcl/adump'，参数文件里涉及到的目录都要在备库创建。
