11GR2 搭建活动的物理DG/DATAGRUAD (READ ONLY模式)

   由于换了一家公司，这家公司全部是用的11GR2+DG，11GR2没有玩过，DG也没有玩过，所以这里在自己的VM里面搭建一个11GR2+DG的测试环境，STANDBY启动到READ ONLY

测试环境为：OS REDHAT  5.6 X86_64,DB  11.2.0.2

安装环境与创建数据库这里就不用说了，很简单的。

整个环境为成4个步骤：

1，主备修改

  1.1 修改参数

  1.2 修改监听

  1.3 cp相关文件到standby上面

  1.4 创建standby日志

2，备备修改

  2.1 修改参数

  2.2 修改监听与测试

  2.3 启动到mount

  2.4 创建相关目录

3，主备duplicate数据库

4，测试DG是否成功

正在开始正式的测试过程

 

1.1 查看数据库是否在归档与是否强制LOGGING模式。

SQL> select log_mode,force_logging from v$database;

LOG_MODE     FOR
------------ ---
ARCHIVELOG   NO

SQL> ALTER DATABASE FORCE LOGGING;

Database altered.

1.2 查看数据库的日志组个数与大小，因为我们创建standby日志组的个数是原日志组个数+1再与thread的积，size不能小于原日志文件的大小。

SQL> select group#,bytes/1024/1024 from v$log;

    GROUP# BYTES/1024/1024
---------- ---------------
         1              50
         2              50
         3              50

SQL> select member from v$logfile;

MEMBER
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/htz/redo03.log
/u01/app/oracle/oradata/htz/redo02.log
/u01/app/oracle/oradata/htz/redo01.log

1.3 创建standby日志组，位置与原日志组相同的路径。创建完成后查询是否成功

SQL> alter database add standby logfile '/u01/app/oracle/oradata/htz/standby01.log' size 50m;

Database altered.

SQL> alter database add standby logfile '/u01/app/oracle/oradata/htz/standby02.log' size 50m;

Database altered.

SQL> alter database add standby logfile '/u01/app/oracle/oradata/htz/standby03.log' size 50m;

Database altered.

SQL> alter database add standby logfile '/u01/app/oracle/oradata/htz/standby04.log' size 50m;

Database altered.
SQL> select group#,status,type,member from v$logfile;

    GROUP# STATUS  TYPE    MEMBER
---------- ------- ------- --------------------------------------------------
         3         ONLINE  /u01/app/oracle/oradata/htz/redo03.log
         2         ONLINE  /u01/app/oracle/oradata/htz/redo02.log
         1         ONLINE  /u01/app/oracle/oradata/htz/redo01.log
         4         STANDBY /u01/app/oracle/oradata/htz/standby01.log
         5         STANDBY /u01/app/oracle/oradata/htz/standby02.log
         6         STANDBY /u01/app/oracle/oradata/htz/standby03.log
         7         STANDBY /u01/app/oracle/oradata/htz/standby04.log

1.4 修改相关的参数，与DG的参数就只与几个参数相关，大概就是日志，文件的位置的转换，GAP的处理，其实GAP已经会自动的处理，不过这里我们还是介绍配置FAL_SERVER,FAL_CLIENT参数。

SQL> alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(htz,htzb)';

System altered.

SQL> alter system set LOG_ARCHIVE_DEST_1='LOCATION=/u01/app/oracle/arch/htz/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=htz';

System altered.

SQL> alter system set LOG_ARCHIVE_DEST_2='SERVICE=htzb LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=htzb';

System altered.

SQL> alter system set LOG_ARCHIVE_DEST_STATE_1=ENABLE;

System altered.

SQL> alter system set FAL_SERVER=htzb;

System altered.

SQL> alter system set FAL_CLIENT=htz;

System altered.

SQL> alter system set db_unique_name=htz scope=spfile;

System altered.

SQL> alter system set db_file_name_convert='/u01/app/oracle/oradata/htz/','/u01/app/oracle/oradata/htz/' scope=spfile;

System altered.

SQL> alter system set log_file_name_convert='/u01/app/oracle/oradata/htz/','/u01/app/oracle/oradata/htz/' scope=spfile;

System altered.

SQL> create pfile from spfile;

File created.

1.5 把dbs下的内容同步到standby主机上面，主要是密码文件（一定要复制过去的）与init文件。

[oracle@11g admin]$ rsync -avlR /u01/app/oracle/product/11.2.0/db_1/dbs/* 192.168.100.31:/

1.6  监听的修改，特别注意这里我们使用了静态的监听，是为了以后我们测试broker时使用的，如果你不用这个，那边可以用动态监听，

1.4 修改/etc/oratab文件，由于OS不一样，这里修改的位置也不一样,如果SUN  /var/opt/oracle/oratab,IBM的/etc/oratab

[root@11gdg ~]# echo "htz:/u01/app/oracle/product/11.2.0/db_1:N">>/etc/oratab
[root@11gdg ~]# tail -1 /etc/oratab
htz:/u01/app/oracle/product/11.2.0/db_1:N

备库的相关操作到此就差不多，到了duplicate的时候了。

回到主备上面。

在前面我们修改了两个参数(db/log_file_name_convertt)到spfile文件中，还没有重启数据库，这里我们重启一下主数据库

下面把备库启动到open only下面。并recover。

下面就是开始测试了。这里我们是用的SCOTT这个用户来做测试，在SCOTT用户下面创建一个表，在备库去查询看是否创建成功，与在主库上面SWIRCH一次日志，看alert中的日志输出内容。

在主库上面做测试
