一、环境说明
开始配置 Oracle Active Data Gurad 之前， 需要事先准备好相应的环境， 根据规划安装主备库的数据库环境，备库只需安装数据库软件，不需要创建实例，本次实施环境全程通过vmware workstation搭建的虚拟机环境进行的测试,，先搭建一个rac gi主库环境，不建库，然后通过虚拟机克隆的方式生成备库的集群环境，再在主库上建库，配置adg的环境。
1、基础环境
| 事项 | 主库 | 备库 |
|---|---|---|

#主机名因为是搭建GI环境后进行克隆的，不好修改备库的主机名，所以主备库主机名这里是一致的。
二、ADG配置
1、配置域名解析文件
1、主库所有节点
192.168.14.145 jbdb1
192.168.14.146 jbdb2
192.168.14.147 jbdb1-vip
192.168.14.148 jbdb2-vip
192.168.14.149 jbdb-scan
192.168.178.131 jbdb1-priv
192.168.178.132 jbdb2-priv
192.168.14.164 jgyldb1
192.168.14.165 jgyldb2
192.168.14.166 jgyldb1-vip
192.168.14.167 jgyldb2-vip
192.168.14.168 jgyldb-scan
2、备库所有节点
192.168.14.164 jbdb1
192.168.14.165 jbdb2
192.168.14.166 jbdb1-vip
192.168.14.167 jbdb2-vip
192.168.14.168 jbdb-scan192.168.179.133 jbdb1-priv
192.168.179.134 jbdb2-priv192.168.14.145 jgyldb1
192.168.14.146 jgyldb2
192.168.14.147 jgyldb1-vip
192.168.14.148 jgyldb2-vip
192.168.14.149 jgyldb-scan
因主机名一致的问题，在写host文件时都是反过来写的。
2、主库开启归档、开启附加日志
#配置归档路径和开启附加日志
SQL>alter system set log_archive_dest_1='location=+data01/jbdb/archive' scope=spfile;
SQL>alter database force logging;#开启归档
[grid@jbdb1 ~]$ srvctl stop database -d jbdbSQL> startup mount
SQL> alter database archivelog;
SQL> alter database open;
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +DATA01/jbdb/archive
Oldest online log sequence 6
Next log sequence to archive 7
Current log sequence 7
SQL> shutdown immediate#启动数据库
[grid@jbdb1 ~]$ srvctl start database -d jbdb#检查归档和附加日志
SQL> select name,open_mode,force_logging from v$database;NAME OPEN_MODE FOR
--------- -------------------- ---
JBDB READ WRITE YESSQL>
3、主库配置归档删除策略
$ rman target /
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO SHIPPED TO ALL STANDBY;
RMAN> show all;RMAN configuration parameters for database with db_unique_name JBDB are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE ; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/snapcf_jbdb1.f'; # defaultRMAN>
4、主库配置 Standby Redo Log
#查看 Online redo log 大小及位置：
SQL> select group#,thread#,members,bytes from v$log;GROUP# THREAD# MEMBERS BYTES
---------- ---------- ---------- ----------1 1 1 524288002 1 1 524288003 2 1 524288004 2 1 52428800SQL> select group#,member from v$logfile;
----GROUP#----------MEMBER--------------------------------------2 +DATA01/jbdb/redo02.log1 +DATA01/jbdb/redo01.log3 +DATA01/jbdb/redo03.log4 +DATA01/jbdb/redo04.log#添加Standby redo log
SQL> alter database add standby logfile thread 1 group 5 '+DATA01/jbdb/redo05_1.log' size 50M;
Database altered.SQL> alter database add standby logfile thread 1 group 6 '+DATA01/jbdb/redo06_1.log' size 50M;
Database altered.SQL> alter database add standby logfile thread 1 group 7 '+DATA01/jbdb/redo07_1.log' size 50M;
Database altered.SQL> alter database add standby logfile thread 2 group 8 '+DATA01/jbdb/redo08_1.log' size 50M;
Database altered.SQL> alter database add standby logfile thread 2 group 9 '+DATA01/jbdb/redo09_1.log' size 50M;
Database altered.SQL> alter database add standby logfile thread 2 group 10 '+DATA01/jbdb/redo10_1.log' size 50M;
Database altered.
SQL>
#检查确认
SQL> select group#,thread#,bytes/1024/1024 Size_MB from v$log;GROUP# THREAD# SIZE_MB
---------- ---------- ----------1 1 502 1 503 2 504 2 50SQL> select group#,thread#,bytes/1024/1024 size_Mb from v$standby_log;GROUP# THREAD# SIZE_MB
---------- ---------- ----------5 1 506 1 507 1 508 2 509 2 5010 2 506 rows selected.
standby redo log的大小与redo log大小相同。组数需要比在线日志多一组。
5、配置 TNSNAMES.ORA 文件
以oracle用户在主库所有节点上配置 tnsname.ora
vi /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
JBDB =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = jbdb1-vip)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = jbdb)))JGYLDB =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = jgyldb1-vip)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = jbdb)))
将主库的tnsnames.ora文件拷贝到备库的所有节点，将修改如下，将名称替换下。
/u01/app/oracle/product/11.2.0/dbhome_1/network/admin
[oracle@jbdb2 admin]$ scp tnsnames.ora jgyldb1:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin
tnsnames.ora 100% 505 0.5KB/s 00:00
[oracle@jbdb2 admin]$ scp tnsnames.ora jgyldb2:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin
tnsnames.ora 100% 505 0.5KB/s 00:00
[oracle@jbdb2 admin]$
登陆备库查看效果如下：
[oracle@jbdb2 admin]$ vi tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.JGYLDB =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = jbdb1-vip)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = jgyldb)))JBDB =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = jgyldb1-vip)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = jbdb)))
6、配置主库 ADG 参数
1、备份spfile文件
SQL>create pfile=’/u01/initbak20211013.ora’ from spfile;
2、配置主库参数
SQL> alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(jbdb,jgyldb)' scope=both;
SQL> alter system set LOG_ARCHIVE_DEST_1='LOCATION=+data01/jbdb/archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=jbdb' scope=both;
SQL> alter system set log_archive_dest_2='SERVICE=jgyldb SYNC NOAFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=jgyldb' scope=both;
SQL> alter system set LOG_ARCHIVE_DEST_STATE_1='ENABLE' scope=both;
SQL> alter system set LOG_ARCHIVE_DEST_STATE_2='ENABLE' scope=both;
SQL> alter system set LOG_FILE_NAME_CONVERT='+DATA01/jgyldb','+DATA01/jbdb' scope=spfile;
SQL> alter system set DB_FILE_NAME_CONVERT='+DATA01/jgyldb','+DATA01/jbdb' scope=spfile;
SQL> alter system set STANDBY_FILE_MANAGEMENT='AUTO' scope=both;
SQL> alter system set FAL_SERVER='jgyldb' scope=both;
3、重启数据库
srvctl stop database -d jbdb
srvctl start database -d jbdb
这里不能按照单实例轮询重启，必须所有节点都关闭重启。
7、配置密码文件
1、将 主库1 节点的密码文件拷贝到主库的所有节点和备库上：
[oracle@jbdb1 ~]$ cd $ORACLE_HOME/dbs
[oracle@jbdb1 dbs]$ scp orapwjbdb1 jgyldb1:$ORACLE_HOME/dbs/orapwjgyldb1
[oracle@jbdb1 dbs]$ scp orapwjbdb1 jgyldb2:$ORACLE_HOME/dbs/orapwjgyldb2
8、创建备库初始化参数文件
1、在主库上生成最新 pfile 文件 ，并拷贝到备库上， 并重命名为 initjgyldb.ora
SQL> create pfile='/tmp/initjbdb.ora' from spfile;File created.
SQL> exit
[oracle@jbdb1 ~]$ scp /tmp/initjbdb.ora jgyldb1:/tmp/initjgyldb.ora
2、修改备库上的 pfile 文件
[oracle@jbdb1 ~]$ more /tmp/initjbdb.ora
jbdb2.__db_cache_size=243269632

jbdb2.thread=2
jbdb1.thread=1
jbdb1.undo_tablespace='UNDOTBS1'
jbdb2.undo_tablespace='UNDOTBS2'
9、创建备库必要目录
1、查看路径
[oracle@jbdb1 ~]$ cat /tmp/initjbdb.ora | grep /
*.audit_file_dest='/u01/app/oracle/admin/jgyldb/adump'
*.control_files='+DATA01/jgyldb/control01.ctl','+DATA01/jgyldb/control02.ctl'
*.db_file_name_convert='+DATA01/jbdb','+DATA01/jgyldb'
*.diagnostic_dest='/u01/app/oracle'
*.log_archive_dest_1='LOCATION=+data01/jgyldb/archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=jgyldb'
*.log_file_name_convert='+DATA01/jbdb','+DATA01/jgyldb'
[oracle@jbdb1 ~]$
2、在备库主机上创建需要的数据库目录
[oracle@jbdb2 ~]$ mkdir -p /u01/app/oracle/admin/jgyldb/adump
[oracle@jbdb2 ~]$ mkdir -p /u01/app/oracle/admin/jgyldb/dpdump
[oracle@jbdb2 ~]$ mkdir -p /u01/app/oracle/admin/jgyldb/hdump
[oracle@jbdb2 ~]$ mkdir -p /u01/app/oracle/admin/jgyldb/pfile
$ su – grid
$ asmcmd
ASMCMD> +DATA01/jgyldb
ASMCMD> mkdir +DATA01/jgyldb
ASMCMD> mkdir +data01/jgyldb/archive
ASMCMD> exit
10、备库 LISTENER 配置
1、grid用户修改listener.ora文件，备库两个节点都需要修改，这里以节点1为例
[grid@jbdb1 admin]$ more /u02/app/oracle/product/11.2.0/grid/network/admin/listener.ora
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by AgentSID_LIST_LISTENER =(SID_LIST =(SID_DESC =(SID_NAME= PLSExtProc)(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)(PROGRAM = extproc))(SID_DESC =(GLOBAL_DBNAME = jbdb)(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)(SID_NAME=jbdb1)))
[grid@jbdb1 admin]$
2、重启监听
[grid@jbdb1 admin]$ srvctl start listener -l LISTENER
11、备库 ADG 初始化
1、启动备库到nomount状态
SQL> startup nomount pfile='/tmp/initjbdb.ora';
2、主库和备库测试连接
[oracle@jbdb2 ~]$ sqlplus sys/admin123@jgyldb as sysdba
[oracle@jbdb2 ~]$ sqlplus sys/admin123@jbdb as sysdba
3、将数据库注册到集群中，1节点执行
[oracle@jbdb1 ~]$ srvctl add database -d jgyldb -o /u01/app/oracle/product/11.2.0/dbhome_1
[oracle@jbdb1 ~]$ srvctl add instance -d jgyldb -i jgyldb1 -n jbdb1
[oracle@jbdb1 ~]$ srvctl add instance -d jgyldb -i jgyldb2 -n jbdb2
4、备库通过 RMAN duplicate 完成进行备库初始化同步
[oracle@jbdb1 ~]$ rman target sys/admin123@jbdb auxiliary sys/admin123@jgyldbRecovery Manager: Release 11.2.0.4.0 - Production on Sun Oct 17 22:39:23 2021Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.connected to target database: JBDB (DBID=680083408)

#确认状态
SQL> select name,db_unique_name,open_mode from v$database;NAME DB_UNIQUE_NAME OPEN_MODE
--------- ------------------------------ --------------------
JBDB jgyldb READ ONLY WITH APPLY12、启动另外一个节点
1、使用pfile生成spfile
SQL> create spfile='+DATA01/jgyldb/spfilejgyldb.ora' from pfile='/tmp/initjbdb.ora' ;
2、创建pfile，内容如下，并将节点1的pfile 拷贝到节点2：
[oracle@jbdb1 ~]$ echo "SPFILE='+DATA01/jgyldb/spfilejgyldb.ora'" > $ORACLE_HOME/dbs/initjgyldb1.ora'
[oracle@jbdb1 ~]$ scp $ORACLE_HOME/dbs/initjgyldb1.ora jbdb2:$ORACLE_HOME/dbs/initjgyldb2.ora
3、重启数据库
[grid@jbdb2 ~]$ srvctl stop database -d jgyldb
[grid@jbdb2 ~]$ srvctl start database -d jgyldb
4、开启实时日志应用
SQL> alter database recover managed standby database disconnect from session using current logfile;Database altered.
5、查看数据库状态
#主库

JBDB jgyldb READ ONLY PHYSICAL STANDBY13、测试adg同步是否正常
1、主库测试建表空间，建用户，建表、插入数据。
SQL> create tablespace adg datafile '+data01/jbdb/adg.dbf' size 50m autoextend on next 100m maxsize unlimited;
Tablespace created.SQL> create user adg identified by adg default tablespace adg;

---------- --------------------2 xxxxxSQL>
2、备库查看所建的表空间、用户、表、数据
SQL> select * from adg.test01;ID NAME
---------- --------------------2 xxxxxSQL>
3、查看 DataGuard 相关进程信息
#主库

[grid@jbdb1 ~]$
3、主备切换：
注：rac to rac的adg切换只需在其中一个节点执行相应命令即可，执行完后，再把另外的节点open
1、在做切换时，主库需要将除了 1 节点之外的所有节点全部关闭：
[grid@jbdb1 ~]$ srvctl stop instance -d jbdb -i jbdb2
2、在主库上执行如下操作， 将主库切换为备库角色
#查看switchover 状态
SQL> select open_mode, switchover_status from v$database;NAME DATABASE_ROLE SWITCHOVER_STATUS
--------- ---------------- --------------------
JBDB PRIMARY TO STANDBY#将主库切换为备库角色
SQL> alter database commit to switchover to physical standby;Database altered.当 SWITCHOVER_STATUS 值为 TO SYANDBY 时，表示主库可以切换为备库角色；
如果主库的 SWITCHOVER_STATUS 值为 SESSIONS ACTIVE， 则表示当前有回话正在连接数据库，则可以执行如下操作完成主备角色切换：
alter database commit to switchover to physical standby with session shutdown;
3、在备库上执行如下操作，将备库转换为主库角色
#查看备库状态
SQL> select open_mode, switchover_status from v$database;OPEN_MODE SWITCHOVER_STATUS
-------------------- --------------------
READ ONLY WITH APPLY TO PRIMARY#切换成主库
SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY WITH SESSION SHUTDOWN;Database altered.
4、检查备库
#如果 STATUS 显示为非 OPEN， 则执行如下操作， 启动数据库
SQL> select instance_name,status from v$instance;INSTANCE_NAME STATUS
---------------- ------------
jbdb1 MOUNTED[root@jbdb2 ~]# su - grid
[grid@jbdb2 ~]$ srvctl stop database -d jbdb
[grid@jbdb2 ~]$ srvctl start database -d jbdb#查看数据库状态，模式已经变成主库
SQL> select instance_name,status from v$instance;INSTANCE_NAME STATUS
---------------- ------------
jbdb1 OPENSQL> select name,database_role,switchover_status from v$database;NAME DATABASE_ROLE SWITCHOVER_STATUS
--------- ---------------- --------------------
JBDB PRIMARY FAILED DESTINATION5、启动备库（原先的主库）
#启动数据库
[grid@jbdb2 ~]$ srvctl start database -d jbdb
#查看数据库模式，此时主库已经切换为物理备库
SQL> select name,database_role,switchover_status from v$database;NAME DATABASE_ROLE SWITCHOVER_STATUS
--------- ---------------- --------------------

在新主库创建表和数据，测试新备库 是否正常同步。
4、发生问题：
1、初始化报错

[oracle@jbdb1 ~]$
经查是备库的oracle文件权限不对，导致无法访问asm磁盘组，需要手动更改两边节点权限
[root@jbdb2 ~]# chown oracle:asmadmin /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
[root@jbdb2 ~]# chmod 6751 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
[root@jbdb2 ~]# ls -l /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
-rwsr-s--x 1 oracle asmadmin 239626641 Oct 11 22:57 /u01/app/oracle/product/11.2.0/dbhome_1/bin/oracle
2、tns访问异常，需要将主备库的tnsnames.ora文件地址全部改成单节点的地址
JGYLDB =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = jbdb1-vip)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = jgyldb)))JBDB =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = jgyldb1-vip)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = jbdb)))
参考
https://www.cnblogs.com/lijiaman/p/11404413.html
如果需要在主库添加或者删除数据文件时，这些文件也会在备库添加或删除，使用如下： sql>alter system set standby_file_management=‘AUTO‘; 默认此参数是manual手工方式
