Oracle 11G Active DataGuard(ADG)搭建配置过程
最简单的11g Active DataGuard(ADG)搭建配置过程（项目步骤）
一、环境介绍:
我在db01和db02两台Linux虚拟机上首先分别安装了一套数据库软件，在db01主机上创建了名为woo的数据库；我们这次的实验是要搭建了一套Oracle 11g Active DataGuard；目的是为了实现数据库同步的功能，并且了解Oracle 11g DG的基本功能。db01:192.168.1.50
db02:192.168.1.51
二、11g ADG部署：
1、pri端和sty端配置静态监听
- [oracle@sty admin]$ cat listener.ora
- # listener.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/listener.ora
- # Generated by Oracle configuration tools.
- SID_LIST_LISTENER =
- (SID_LIST =
- (SID_DESC =
- (SID_NAME = PLSExtProc)
- (ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
- (PROGRAM = extproc)
- )
- (SID_DESC =
- (SID_NAME = Woo )
- (ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
- )
- )
- [oracle@sty admin]$cat tnsname.ora
- # tnsnames.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/tnsnames.ora
- # Generated by Oracle configuration tools.
- STY =
- (DESCRIPTION =
- (ADDRESS_LIST =
- (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.51)(PORT = 1521))
- )
- (CONNECT_DATA =
- (SERVICE_NAME = woo)
- )
- )
- PRI =
- (DESCRIPTION =
- (ADDRESS_LIST =
- (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.50)(PORT = 1521))
- )
- (CONNECT_DATA =
- (SERVICE_NAME = woo)
- )
- )
2、修改primary端初始化参数文件
- startup mount;
- alter database archivelog;
- alter database force logging;
- alter database open;
- alter system set log_archive_config = 'DG_CONFIG=(pri,sty)' scope=spfile;
- alter system set log_archive_dest_1 = 'LOCATION=/DBBackup/Archive VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=pri' scope=spfile;
- alter system set log_archive_dest_2 = 'SERVICE=sty LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=sty' scope=spfile;
- alter system set log_archive_dest_state_1 = ENABLE;
- alter system set log_archive_dest_state_2 = ENABLE;
- alter system set fal_server=sty scope=spfile;
- alter system set fal_client=pri scope=spfile;
- alter system set standby_file_management=AUTO scope=spfile;
3、在primary端pfile参数文件和密码文件，并且拷贝到standby段相应位置
- SQL> create pfile from spfile;
- File created.
- [oracle@db01 dbs]$ scp initwoo.ora orapwwoo db02:/DBSoft/oracle/product/11.2.4/dbhome_1/dbs
- oracle@192.168.1.51's password:
- initwoo.ora 100% 1260 1.2KB/s 00:00
- orapwwoo 100% 1536 1.5KB/s 00:00
- [oracle@db01 oracle]$ scp -r admin/ diag/ fast_recovery_area/ oradata/ 192.168.1.51:$ORACLE_BASE
- oracle@192.168.1.51's password:
- init.ora.512201522543 100% 1778 1.7KB/s 00:01
- dp.log 100% 116 0.1KB/s 00:00
- ........
4、修改standby端的监听文件及初始化参数文件
- --修改监听文件
- [oracle@db02 ~]$ cd $ORACLE_HOME/network/admin
- [oracle@db02 admin]$ vi listener.ora
- # listener.ora Network Configuration File: /DBSoft/oracle/product/11.2.4/dbhome_1/network/admin/listener.ora
- # Generated by Oracle configuration tools.
- LISTENER =
- (DESCRIPTION_LIST =
- (DESCRIPTION =
- (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
- (ADDRESS = (PROTOCOL = TCP)(HOST = db02)(PORT = 1521))
- )
- )
- SID_LIST_LISTENER =
- (SID_LIST =
- (SID_DESC =
- (SID_NAME = PLSExtProc)
- (ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
- (PROGRAM = extproc)
- )
- (SID_DESC =
- (GLOBAL_DBNAME = woo)
- (ORACLE_HOME = /DBSoft/oracle/product/11.2.4/dbhome_1)
- (SID_NAME = woo)
- )
- )
- ADR_BASE_LISTENER = /DBSoft/oracle
- --启动监听
- [oracle@db02 dbs]$ lsnrctl start

#至此已经恢复完成
6、在primary 和standby端添加standby日志
- SQL> alter database add standby logfile
- group 4 ('/DBSoft/oracle/oradata/woo/styredo04.log') size 50m,
- group 5 ('/DBSoft/oracle/oradata/woo/styredo05.log') size 50m,
- group 6 ('/DBSoft/oracle/oradata/woo/styredo06.log') size 50m,
- group 7 ('/DBSoft/oracle/oradata/woo/styredo07.log') size 50m;
- SQL> SELECT GROUP#,THREAD#,SEQUENCE#,ARCHIVED,STATUS FROM V$STANDBY_LOG;
- GROUP# THREAD# SEQUENCE# ARC STATUS
- ---------- ---------- ---------- --- ----------
- 4 0 0 YES UNASSIGNED
- 5 0 0 YES UNASSIGNED
- 6 0 0 YES UNASSIGNED
- 7 0 0 YES UNASSIGNED
7、在standby端开启实时日志应用
- SQL> recover managed standby database using current logfile disconnect from session;
- Media recovery complete.
- SQL>
三、开始测试ADG
8、执行日志切换测试（在pri端切换归档，在节点二上检查是否也发生了切换）
- --primary执行日志切换
- SQL> archive log list;
- Database log mode Archive Mode
- Automatic archival Enabled
- Archive destination /DBBackup/Archive
- Oldest online log sequence 21
- Next log sequence to archive 23
- Current log sequence 23
- SQL> alter system switch logfile;
- System altered.
- SQL> archive log list;
- Database log mode Archive Mode
- Automatic archival Enabled
- Archive destination /DBBackup/Archive
- Oldest online log sequence 22
- Next log sequence to archive 23
- Current log sequence 24
- #standby查看日志的sequence号也跟着变了
- SQL> archive log list;
- Database log mode Archive Mode
- Automatic archival Enabled
- Archive destination /DBBackup/Archive
- Oldest online log sequence 22
- Next log sequence to archive 0
- Current log sequence 23
- SQL> archive log list;
- Database log mode Archive Mode
- Automatic archival Enabled
- Archive destination /DBBackup/Archive
- Oldest online log sequence 22
- Next log sequence to archive 0
- Current log sequence 24
- SQL>
9、查看standby启动的DG进程
- SQL> select process,client_process,sequence#,status from v$managed_standby;
- PROCESS CLIENT_P SEQUENCE# STATUS
- --------- -------- ---------- ------------
- ARCH ARCH 23 CLOSING
- ARCH ARCH 0 CONNECTED //归档进程
- ARCH ARCH 21 CLOSING
- ARCH ARCH 0 CONNECTED
- RFS ARCH 0 IDLE
- RFS UNKNOWN 0 IDLE
- RFS LGWR 24 IDLE //归档传输进程
- RFS UNKNOWN 0 IDLE
- MRP0 N/A 24 APPLYING_LOG //日志应用进程
- 9 rows selected.
10、查看数据库的保护模式：
- #primary 端查看，我们可以看到数据库的保护模式为最大性能
- SQL> select database_role,protection_mode,protection_level,open_mode from v$database;
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL OPEN_MODE
- ---------------- -------------------- -------------------- --------------------
- PRIMARY MAXIMUM PERFORMANCE MAXIMUM PERFORMANCE READ WRITE
- #standby 端查看，也是一样的。
- SQL> select database_role,protection_mode,protection_level,open_mode from v$database;
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL OPEN_MODE
- ---------------- -------------------- -------------------- --------------------
- PHYSICAL STANDBY MAXIMUM PERFORMANCE MAXIMUM PERFORMANCE MOUNTED
11、查看DG的日志信息
- SQL> select * from v$dataguard_status;
- FACILITY SEVERITY DEST_ID MESSAGE_NUM ERROR_CODE CAL TIMESTAMP MESSAGE
- ------------------------ ------------- ---------- ----------- ---------- --- --------- --------------------------------------------------------------------------------

13、解锁scott用户，添加数据，验证数据是否能同步：
- #在primary端创建解锁scott用户并创建测试表，插入10000行数据
- #primary 端操作如下内容
- SQL> set line 200
- SQL> select username,default_tablespace,account_status from dba_users where username='SCOTT';
- USERNAME DEFAULT_TABLESPACE ACCOUNT_STATUS
- ------------------------------ ------------------------------ --------------------------------
- SCOTT USERS EXPIRED & LOCKED
- SQL> alter user scott account unlock;
- User altered.
- SQL> conn scott/tiger;
- ERROR:
- ORA-28001: the password has expired
- Changing password for scott
- New password:

#至此Oracle 11g ADG就已经配置完成了
四、ADG三种模式切换及介绍
14、#ADG有三种(PROTECTION|AVAILABILITY|PERFORMANCE)模式，具体参考:探索Oracle11gR2 之 DataGuard_03 三种保护模式
- --primary操作步骤也就是命令之差：
- SQL> select database_role,protection_mode,protection_level from v$database; ----当前为最大性能
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL
- ---------------- -------------------- --------------------
- PRIMARY MAXIMUM PERFORMANCE MAXIMUM PERFORMANCE
- SQL>
- SQL> alter database set standby database to maximize availability; ----切换为最大可用
- Database altered.
- SQL> select database_role,protection_mode,protection_level from v$database;
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL
- ---------------- -------------------- --------------------
- PRIMARY MAXIMUM AVAILABILITY MAXIMUM AVAILABILITY
- SQL> alter database set standby database to maximize protection; ----切换为最大保护
- Database altered.
- SQL> select database_role,protection_mode,protection_level from v$database;
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL
- ---------------- -------------------- --------------------
- PRIMARY MAXIMUM PROTECTION MAXIMUM PROTECTION
- SQL>
- --#standby端切换到最大保护是需要重启数据库到mount模式的:
- SQL> select database_role,protection_mode,protection_level from v$database; ----当前为最大性能
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL
- ---------------- -------------------- --------------------
- PHYSICAL STANDBY MAXIMUM PERFORMANCE MAXIMUM PERFORMANCE
- SQL> alter database set standby database to maximize availability; ----切换为最大可用
- Database altered.
- SQL> select database_role,protection_mode,protection_level from v$database;
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL
- ---------------- -------------------- --------------------
- PHYSICAL STANDBY MAXIMUM AVAILABILITY MAXIMUM AVAILABILITY
- SQL> alter database set standby database to maximize protection; ----切换为最大保护模式报错，需要将standby端启动到mount状态切换.
- alter database set standby database to maximize protection
- *
- ERROR at line 1:
- ORA-01126: database must be mounted in this instance and not open in any instance
- SQL> shutdown immediate ----将数据库启动到mount状态
- Database closed.
- Database dismounted.
- ORACLE instance shut down.
- SQL> startup mount;
- ORACLE instance started.
- Total System Global Area 1188511744 bytes
- Fixed Size 1364228 bytes
- Variable Size 754978556 bytes
- Database Buffers 419430400 bytes
- Redo Buffers 12738560 bytes
- Database mounted.
- SQL> alter database set standby database to maximize protection; ----再次切换为最大可用，成功。
- Database altered.
- SQL> recover managed standby database using current logfile disconnect from session;
- Media recovery complete.
- SQL> select database_role,protection_mode,protection_level from v$database;
- DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL
- ---------------- -------------------- --------------------
- PHYSICAL STANDBY MAXIMUM PROTECTION MAXIMUM PROTECTION
五、切换测试
15、ADG做(switchover)切换测试
- --primary 做如下操作
- SQL> alter database commit to switchover to physical standby;
- Database altered.
- SQL> shutdown immediate
- ORA-01012: not logged on
- SQL> conn / as sysdba
- Connected to an idle instance.
- SQL> startup
- ORACLE instance started.
- Total System Global Area 1188511744 bytes
- Fixed Size 1364228 bytes
- Variable Size 754978556 bytes
- Database Buffers 419430400 bytes
- Redo Buffers 12738560 bytes
- Database mounted.
- Database opened.
- SQL> alter database recover managed standby database disconnect from session;
- Database altered.
- SQL> select database_role,switchover_status from v$database;
- DATABASE_ROLE SWITCHOVER_STATUS
- ---------------- --------------------
- PHYSICAL STANDBY TO PRIMARY
- SQL>
- --standby 端做如下操作
- SQL> alter database commit to switchover to primary;
- Database altered.
- SQL> shutdown immediate
- ORA-01109: database not open
- Database dismounted.
- ORACLE instance shut down.
- SQL> startup
- ORACLE instance started.
- Total System Global Area 1188511744 bytes
- Fixed Size 1364228 bytes
- Variable Size 754978556 bytes
- Database Buffers 419430400 bytes
- Redo Buffers 12738560 bytes
- Database mounted.
- Database opened.
- SQL> alter system switch logfile;
- System altered.
- SQL> select database_role,switchover_status from v$database;
- DATABASE_ROLE SWITCHOVER_STATUS
- ---------------- --------------------
- PRIMARY SESSIONS ACTIVE
- SQL>
16、ADG做(fail over)切换测试
- --standby 端检查状态
- SQL> select open_mode from v$database;
- OPEN_MODE
- --------------------
- READ ONLY WITH APPLY
- --我们通过shutdown abort方式人工模拟primary奔溃，直接关闭:
- SQL> select open_mode from v$database;
- OPEN_MODE
- --------------------
- READ WRITE
- SQL> shutdown abort
- ORACLE instance shut down.
- SQL>
- --在standby端执行如下操作
- SQL> startup mount;
- ORACLE instance started.
- Total System Global Area 1188511744 bytes
- Fixed Size 1364228 bytes
- Variable Size 754978556 bytes
- Database Buffers 419430400 bytes
- Redo Buffers 12738560 bytes
- Database mounted.
- SQL> alter system flush redo to 'pri';
- System altered.
- SQL> select thread#, low_sequence#, high_sequence# from v$archive_gap;
- no rows selected
- --如果没有发现明显的gap现象，说明此次的failover不会有数据损失情况。在standby端，要进行关闭apply和结束应用动作。
- SQL> alter database recover managed standby database cancel;
- Database altered.
- SQL> alter database recover managed standby database finish;
- Database altered
- SQL> select open_mode, switchover_status from v$database;
- OPEN_MODE SWITCHOVER_STATUS
- -------------------- --------------------
- READ ONLY TO PRIMARY
