Oracle 11g Active Dataguard （RAC）的配置

2024-08-02 05:47:36 222人阅读

一：环境介绍
主库(RAC)
IP地址:192.168.1.210,192.168.1.211
操作系统版本：ole5.8 64bit
数据库版本：11.2.0.4 64bit
数据库sid名：MECBS1,MECBS2
数据库主机名：node1,node2
数据库db_unique_name:MECBS

备库1 物理备库（只安装oracle数据库软件，无需建库）
IP地址:192.168.1.219
操作系统版本：ole5.8 64bit
数据库版本：11.2.0.4 64bit
数据库sid名：PHUB
数据库主机名：dataguard
数据库db_unique_name:PHUB

主库和备库均采用ASM管理

二.通过网络DUPLICAT 复制备库：

1.配置备库监听：

LISTENER =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=dataguard)(PORT=1521))
(ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=PHUB)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1)
(SID_NAME=PHUB)
)
)

2.TNS配置（主库各节点和备库）：

MECBS1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.210)(PORT = 1521))
(CONNECT_DATA =http://www.mamicode.com/
(SERVER = DEDICATED)
(SERVICE_NAME = MECBS)
(SERVICE_NAME = MECBS1)
)
)
MECBS2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.211)(PORT = 1521))
(CONNECT_DATA =http://www.mamicode.com/
(SERVER = DEDICATED)
(SERVICE_NAME = MECBS)
(SERVICE_NAME = MECBS2)
)
)
PHUB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.219)(PORT = 1521))
(CONNECT_DATA =http://www.mamicode.com/
(SERVER = DEDICATED)
(SERVICE_NAME = PHUB)
)
)
配置完成后用tnsping验证

3.检查主库归档情况：

SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +RECO
Oldest online log sequence 7
Next log sequence to archive 8
Current log sequence 8

4.为了能主备切换，配置主数据库的Standby Redo日志，执行下面SQL语句查询主库联机REDO日志：

SQL> select thread#,bytes/1024/1024 "SIZE(MB)",MEMBERS FROM V$LOG;
THREAD# SIZE(MB) MEMBERS
---------- ---------- ----------
1 50 1
1 50 1
2 50 1
2 50 1

当前RAC环境包含2个节点，每个节点有两个日志组，每个日志组大小为50M，每个日志组有两个成员，根据这个情况，为每个节点添加3个大小为50M，每个日志组包含2个成员，分别位于DATA和RECO磁盘组：

SQL> alter database add standby logfile thread 1(‘+DATA‘,‘+RECO‘) size 50M;
Database altered.
SQL> alter database add standby logfile thread 1(‘+DATA‘,‘+RECO‘) size 50M;
Database altered.
SQL> alter database add standby logfile thread 1(‘+DATA‘,‘+RECO‘) size 50M;
Database altered.
SQL> alter database add standby logfile thread 2(‘+DATA‘,‘+RECO‘) size 50M;
Database altered.
SQL> alter database add standby logfile thread 2(‘+DATA‘,‘+RECO‘) size 50M;
Database altered.
SQL> alter database add standby logfile thread 2(‘+DATA‘,‘+RECO‘) size 50M;
Database altered.

``5.修改主库参数文件：

SQL> create pfile=‘/home/oracle/pfile.ora1‘ from spfile;
File created.

[oracle@node2 ~]$ cat pfile.ora1
MECBS2.__db_cache_size=251658240

*.standby_file_management=auto
*.log_archive_dest_1=‘location=+RECO valid_for=(all_logfiles,all_roles) db_unique_name=MECBS‘

SQL> create spfile from pfile=‘/home/oracle/pfile.ora1‘;
File created.

用修改过的pfile文件启动另外的节点：

SQL> startup pfile=‘/home/oracle/pfile.ora1‘;
ORACLE instance started.
Total System Global Area 484356096 bytes
Fixed Size 2254464 bytes
Variable Size 264243584 bytes
Database Buffers 209715200 bytes
Redo Buffers 8142848 bytes
Database mounted.
Database opened.

创建主库的spfile文件：

SQL> create spfile=‘+DATA/MECBS/spfileMECBS.ora‘ from pfile=‘/home/oracle/pfile.ora1‘;
File created.

6.完全备份主库：

[oracle@node2 ~]$ rman target /

拷贝密码文件和参数文件到备库并重命名：

[oracle@node1 dbs]$ scp orapwMECBS1 192.168.1.219:/u01/app/oracle/product/11.2.0/db_1/dbs/orapwPHUB

9.启动Redo Apply

（1）查看实例状态：

SQL> select status from v$instance;
STATUS
------------
MOUNTED

（2）打开数据库（11g可以以只读的方式打开）：

SQL> alter database open;
Database altered.
SQL> select open_mode from v$database;
OPEN_MODE
--------------------
READ ONLY

（3）启动redo apply

SQL> alter database recover managed standby database using current logfile disconnect from session;
Database altered.

10.注册standby为restart数据库：

（1）查看监听注册情况：

[oracle@dataguard ~]$ srvctl status listener -l listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): dataguard

如果没有注册，用以下命令注册：

srvctl add listener -l listener -o /u01/app/11.2.0/grid/(grid用户家目录) -s

（2）将database注册为clusterware资源：

[oracle@dataguard ~]$ srvctl add database -d PHUB -o /u01/app/oracle/product/11.2.0/db_1/

[oracle@dataguard ~]$ srvctl start database -d PHUB
[oracle@dataguard ~]$ srvctl status database -d PHUB
Database is running.

（3）查看clusterware资源状态：

[grid@dataguard ~]$ crsctl stat res -t

ora.phub.db
1 ONLINE ONLINE dataguard Open

11.正常开启和关闭DATAGUARD流程：

（1)正常关闭：执行以下sql停止standby数据库redo日志应用：

alter database recover managed standby database cancel

关闭主数据库======》关闭standby数据库

（2）启动standby数据库====================》启动主数据库========》启动standby数据库redo日志应用。

12.监控日志传输服务：

（1）检查实例名对应的线程号：

SQL> select thread#,instance_name from gv$instance;
THREAD# INSTANCE_NAME
---------- ----------------
2 MECBS2
1 MECBS1

（2）检查每个实例所有目的地生成日志的最大序列号：

SQL> select thread#,dest_id,max(sequence#) from v$archived_log group by thread#,dest_id order by thread#;
THREAD# DEST_ID MAX(SEQUENCE#)
---------- ---------- --------------
1 1 22
1 2 22
2 1 19
2 2 19

上面结果表示所有实例的日志都成功归档到所有目的地：

手动切换RAC所有节点日志：

SQL> alter system archive log current;
System altered.
SQL> /
System altered.

上面结果表示所有实例的日志都成功归档到所有目的地：

13.查看standby数据库使用情况：

SQL> select thread#,sequence#,archived,status from v$standby_log;
THREAD# SEQUENCE# ARC STATUS
---------- ---------- --- ----------
1 27 YES ACTIVE
1 0 NO UNASSIGNED
1 0 YES UNASSIGNED
2 24 YES ACTIVE
2 0 NO UNASSIGNED
2 0 YES UNASSIGNED
6 rows selected.

在主库上查询日志序列号：

SQL> select thread#,sequence#,status from v$log;
THREAD# SEQUENCE# STATUS
---------- ---------- ----------------
1 27 CURRENT
1 26 INACTIVE
2 23 INACTIVE
2 24 CURRENT

证明传输服务启动了实时传输。
