Oracle ADG方式 搭建 DG
作者：互联网
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
SQL> select * from v$version;
BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
PL/SQL Release 11.2.0.4.0 - Production
CORE 11.2.0.4.0 Production
TNS for Linux: Version 11.2.0.4.0 - Production
NLSRTL Version 11.2.0.4.0 - Production
主库:192.168.56.67
备库:192.168.56.68
2 主库设置为 force logging 模式
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
Total System Global Area 1043886080 bytes
Fixed Size 2259840 bytes
Variable Size 889193600 bytes
Database Buffers 146800640 bytes
Redo Buffers 5632000 bytes

---
YES
--取消force logging命令
SQL> alter database no force logging;
Database altered.
SQL> select force_logging from v$database;
FOR
---
NO
3 修改主库为归档模式
--创建归档目录并赋权限
[root@localhost ~]# mkdir /u01/archive
[root@localhost ~]# chown oracle:oinstall /u01/archive
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.

Redo Buffers 5632000 bytes
Database mounted.
SQL> archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 5
Current log sequence 7
SQL> alter database archivelog;
Database altered.
SQL> alter system set log_archive_dest_1='location=/u01/archive/' scope=spfile;
System altered.
SQL> archive log list

Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 5
Next log sequence to archive 7

4 添加主库的 standby redo log
主库添加 standby redo log：大小和 online redo 相同，比 online redo group 多一组。
SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 4 ('/u01/app/oracle/oradata/orcl/redo04.log') size 50M;
Database altered.
SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 5 ('/u01/app/oracle/oradata/orcl/redo05.log') size 50M;
Database altered.
SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 6 ('/u01/app/oracle/oradata/orcl/redo06.log') size 50M;
Database altered.
SQL> ALTER DATABASE ADD STANDBY LOGFILE GROUP 7 ('/u01/app/oracle/oradata/orcl/redo07.log') size 50M;
Database altered.
SQL> select GROUP#,SEQUENCE#,BYTES/1024/1024,STATUS from v$log;
GROUP# SEQUENCE# BYTES/1024/1024 STATUS
---------- ---------- --------------- ----------------

2 5 50 INACTIVE
SQL> col member for a50
SQL> select group#,type, member from v$logfile;

7 STANDBY /u01/app/oracle/oradata/orcl/redo07.log
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/oracle
SID_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
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
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 =
(SERVICE_NAME = orcl)
)
)
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

机器的防火墙已开启，但没有开放该1521端口

vi /etc/sysconfig/iptables
添加一行

OK (10 msec)
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/orcl
8 在主库创建 pfile 文件并修改 pfile 内容
SQL> create pfile from spfile;
File created.
修改pfile
orcl.__db_cache_size=146800640
orcl.__java_pool_size=4194304
orcl.__large_pool_size=587202560
orcl.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment

*.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
SQL> startup nomount ORA-00845: MEMORY_TARGET not supported on this system SQL> startup nomount pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initorcl.ora' ORACLE instance started.

SQL> create spfile from pfile; File created.
9 将主库的口令文件，参数文件 copy 到备库并修改
[oracle@localhost dbs]$ scp initorcl.ora 192.168.56.68:/u01/app/oracle/product/11.2.0/db_1/dbs

10 用 spfile 将备库启动到 nomount 状态
SQL> conn /as sysdba
ERROR:
ORA-09925: Unable to create audit trail file
Linux-x86_64 Error: 2: No such file or directory
Additional information: 9925
ORA-01075: you are currently logged on
检查原因原来是 /u01/app/oracle/admin/orcl 目录下adump 未建
[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。

这个操作主备库都可以，只要在 RMAN 连接时没写错就可以了。
