10G 搭建物理备库（restore、recover方式）

下面是在LINUX平台测试10G搭建物理备库，使用restore,recover的方式。

测试环境是：OS RHEL 4.8 DB 10.2.0.4

1.安装备库的ORACLE软件

建议使用clone的方式来安装备库的软件，这样不需要安装patch这些，并且clone的安装的方式很快。见连接使用clone方式安装数据库

2.主库配置tnsnames.ora文件

增加上备库数据库的网络服务名

ORCL10GDG =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.4)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl10g)
    )
  )

ORCL10G =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = rhel4)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl10g)
    )
  )

3.修改参数文件

#修改归档与日志传输相关的参数
#这个参数用于控制DG环境中日志从那里接收与传送到到那里，后面的名字由db_unique_name来确定
www.htz.pw >alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcl10g,orcl10gdg)';

System altered.
#定义本地归档的路径，VALID_FOR用于指定日志的TYPE与DB ROLE
www.htz.pw >alter system set LOG_ARCHIVE_DEST_1='LOCATION=/arch/orcl10g/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=orcl10g';

System altered.
#定义远程日志传输位置，这个配置使用ARCH来传输，ASYNC方式传输。
www.htz.pw >alter system set LOG_ARCHIVE_DEST_2='SERVICE=orcl10gdg ARCH ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl10gdg';

System altered.
#启用路径1，这个默认就是enable
www.htz.pw >alter system set LOG_ARCHIVE_DEST_STATE_1=ENABLE;

System altered.

#配置备库接收到主库的归档日志的存放位置

www.htz.pw >alter system set standby_archive_dest='/arch/orcl10g/';

System altered.
#配置备库相关文件的管理方式，AUTO表示备库自动创建相关的文件如果存在就会覆盖。
www.htz.pw >alter system set standby_file_management=AUTO ;

System altered.

#配置FAL参数
#FAL_SERVER代表是从那里获取日志（网络服务名）。
www.htz.pw >alter system set FAL_SERVER=orcl10gdg;

System altered.
#指定归档日志传输到那里去（网络服务名），fal_server与fal_client是同时配置的
www.htz.pw >alter system set FAL_CLIENT=orcl10g;
另外一个参数db_name需要注意，所有dg中的db_name必须一致

4.配置standby日志组

#STANDBY日志组的个数日志组个数+1，
www.htz.pw >select group#,bytes/1024/1024 from v$log;

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

www.htz.pw >select member from v$logfile;

MEMBER
-----------------------------------------
/datafile/orcl10g/orcl10g/redo03.log
/datafile/orcl10g/orcl10g/redo02.log
/datafile/orcl10g/orcl10g/redo01.log

#standby日志文件大小不能小于普通日志文件大小
www.htz.pw >alter database add standby logfile '/datafile/orcl10g/orcl10g/standby_redo01.log' size 50m;

Database altered.

www.htz.pw >alter database add standby logfile '/datafile/orcl10g/orcl10g/standby_redo02.log' size 50m;

Database altered.

www.htz.pw >alter database add standby logfile '/datafile/orcl10g/orcl10g/standby_redo03.log' size 50m;

Database altered.

www.htz.pw >alter database add standby logfile '/datafile/orcl10g/orcl10g/standby_redo04.log' size 50m;

Database altered.

5.启动强制日志

www.htz.pw >alter database force logging;

Database altered.

6.修改目录对应关系

#配置数据文件与日志文件目录对应关系，这个参数不能在OPEN阶段修改，所以在10G中需要关库，11G中不存在
www.htz.pw >startup force mount;
ORACLE instance started.

Total System Global Area  440401920 bytes
Fixed Size                  2084552 bytes
Variable Size             125829432 bytes
Database Buffers          306184192 bytes
Redo Buffers                6303744 bytes
Database mounted.

#配置配置文件目录对象关系，如果RAW的时候不需要配置
www.htz.pw >alter system set db_file_name_convert='/datafile/orcl10g/orcl10g/', '/datafile/orcl10g/orcl10g/' scope=spfile;

System altered.
#配置日志文件目录对象文件
www.htz.pw >alter system set log_file_name_convert='/datafile/orcl10g/orcl10g/', '/datafile/orcl10g/orcl10g/' scope=spfile;

System altered.

重启数据库，创建pfile文件
www.htz.pw >startup force                                    
ORACLE instance started.

Total System Global Area  440401920 bytes
Fixed Size                  2084552 bytes
Variable Size             125829432 bytes
Database Buffers          306184192 bytes
Redo Buffers                6303744 bytes
Database mounted.
Database opened.
#创建pfile文件，用于备库修改
www.htz.pw >create pfile='/soft/backup/test.ora' from spfile;

File created.

7.备份数据库与控制文件

#全库ORACLE数据库，如果已经有全库，这里我们可以不用再备份了。
[oracle10g@rhel4 ~]$ cat rman_backup.sh
rman target / <<EOF
RUN {
ALLOCATE CHANNEL ch00 TYPE DISK;
BACKUP
    SKIP INACCESSIBLE
    TAG hot_db_bk_level0
    FORMAT '/soft/backup/bk_%s_%p_%t'
    DATABASE;
    sql 'alter system archive log current';
BACKUP
                FORMAT '/soft/backup/ar_%s_%p_%t'

                CURRENT CONTROLFILE;

}
exit
EOF
#把备份放到后台运行
[oracle10g@rhel4 ~]$ chmod 777 rman_backup.sh
[oracle10g@rhel4 ~]$ nohup sh rman_backup.sh >rman_backup.log &

#备份控制文件，如果在生产环境中，建议在standby已经启动来nomount的时候再来备份控制文件，再SCP过去都可以。
RMAN> backup current controlfile for standby format '/soft/backup/stdb_cntl.bkp';

到此主库的操作完成

由于这里我两台主机他们都是mount的WIN下面的一个共享目录到/soft所以这里我不需要传输到STANDBY主机。在传输的时候需要使用binary的方式来传输。

8.备库配置listener与tnsnames文件

#这里我们可以通过netca与netmgr等图形界面来配置，也可以手动修改相关文件来配置
[oracle10g@test ~]$ cd $ORACLE_HOME/network/admin
[oracle10g@test admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER_10G =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.4)(PORT = 1521))
    )
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
  )

SID_LIST_LISTENER_10G =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = orcl10g)
      (ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
      (SID_NAME = orcl10g)
    )
  )

[oracle10g@test admin]$ cat tnsnames.ora

ORCL10G =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.111.2)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl10g)
    )
  )

ORCL10GDG =
  (DESCRIPTION =

  )
#启动监听

9.修改备库的参数文件

[oracle10g@test admin]$ export ORACLE_SID=orcl10g
#这里注意，部分参数是跟主库是不一样的
[oracle10g@test backup]$ cat test.ora
*.background_dump_dest='/u01/app/oracle/admin/orcl10g/bdump'

*.undo_tablespace='UNDOTBS1'
*.user_dump_dest='/u01/app/oracle/admin/orcl10g/udump'

10.创建相关目录与密码文件

mkdir -p /datafile/orcl10g/orcl10g/
mkdir -p /u01/app/oracle/flash_recovery_area
mkdir -p /arch/orcl10g/
mkdir -p /u01/app/oracle/admin/orcl10g/bdump
mkdir -p /u01/app/oracle/admin/orcl10g/adump
mkdir -p /u01/app/oracle/admin/orcl10g/cdump
mkdir -p /u01/app/oracle/admin/orcl10g/udump
mkdir -p /u01/app/oracle/admin/orcl10g/dpdump
mkdir -p /u01/app/oracle/admin/orcl10g/pfile
#这里最好把源库中的密码文件CP过来就可以了
[oracle10g@test backup]$ orapwd file=$ORACLE_HOME/dbs/orapworcl10g password=oracle entries=1000 force=y

11.创建spfile文件

[oracle10g@test datafile]$ cd /soft/backup
[oracle10g@test backup]$ sqlplus / as sysdba
