Linux下DG环境的搭建及升级（step by step）

1、  测试环境

ORACLE主库IP：10.1.1.14  SID:YEYEAI

ORACLE 从库IP：10.1.1.25  SID:STANDBY

2、  修改主库参数文件为：fuck.ora （红色为修改的部分）

YEYEAI.__db_cache_size=88080384

YEYEAI.__java_pool_size=4194304

YEYEAI.__large_pool_size=4194304

YEYEAI.__shared_pool_size=67108864

YEYEAI.__streams_pool_size=0

*.audit_file_dest='/oracle/app/admin/YEYEAI/adump'

*.background_dump_dest='/oracle/app/admin/YEYEAI/bdump'

*.compatible='10.2.0.1.0'

*.control_files='/oracle/app/oradata/YEYEAI/control01.ctl','/oracle/app/oradata/YEYEAI/control02.ctl','/oracle/app/oradata/YEYEAI/co

ntrol03.ctl'

*.core_dump_dest='/oracle/app/admin/YEYEAI/cdump'

*.db_block_size=8192

*.db_name='YEYEAI'

*.db_domain=''

*.db_file_multiblock_read_count=16

*.db_recovery_file_dest='/oracle/app/flash_recovery_area'

*.db_recovery_file_dest_size=2147483648

*.dispatchers='(PROTOCOL=TCP) (SERVICE=YEYEAIXDB)'

*.job_queue_processes=10

*.open_cursors=300

*.pga_aggregate_target=16777216

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=167772160

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

*.user_dump_dest='/oracle/app/admin/YEYEAI/udump'

STANDBY_ARCHIVE_DEST='/oracle/app/flash_recovery_area/YEYEAI/archivelog'

db_unique_name='yeyeai'

LOG_ARCHIVE_CONFIG='DG_CONFIG=(yeyeai,standby)'

LOG_ARCHIVE_DEST_1='LOCATION=/oracle/app/flash_recovery_area/YEYEAI/archivelog VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=YEYEAI'

LOG_ARCHIVE_DEST_2='SERVICE=standby LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=standby'

FAL_SERVER=standby

FAL_CLIENT=yeyeai

DB_FILE_NAME_CONVERT='/oracle/app/oradata/YEYEAI','/oracle/oradata/STANDBY'

LOG_FILE_NAME_CONVERT='/oracle/app/oradata/YEYEAI','/oracle/oradata/STANDBY'

STANDBY_FILE_MANAGEMENT=AUTO

3、  修改从库的配置文件为：fuck.ora

*.audit_file_dest='/oracle/app/admin/STANDBY/adump'

*.background_dump_dest='/oracle/app/admin/STANDBY/bdump'

*.compatible='10.2.0.1.0'

*.control_files='/oracle/oradata/STANDBY/control01.ctl','/oracle/oradata/STANDBY/control02.ctl','/oracle/oradata/STANDBY/control03.ctl'

*.core_dump_dest='/oracle/app/admin/STANDBY/cdump'

*.db_16k_cache_size=16777216

*.db_block_size=8192

*.db_domain=''

*.db_file_multiblock_read_count=16

*.db_recovery_file_dest='/oracle/app/flash_recovery_area'

*.db_recovery_file_dest_size=2147483648

*.dispatchers='(PROTOCOL=TCP) (SERVICE=STANDBYXDB)'

*.job_queue_processes=10

*.open_cursors=300

*.pga_aggregate_target=16777216

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=167772160

*.undo_management='AUTO'

*.db_name='YEYEAI'

*.undo_tablespace='UNDOTBS2'

*.user_dump_dest='/oracle/app/admin/STANDBY/udump'

DB_UNIQUE_NAME='YEYEAI'

LOG_ARCHIVE_CONFIG='DG_CONFIG=(yeyeai,standby)'

DB_FILE_NAME_CONVERT='/oracle/app/oradata/YEYEAI','/oracle/oradata/STANDBY'

LOG_FILE_NAME_CONVERT='/oracle/app/oradata/YEYEAI','/oracle/oradata/STANDBY'

LOG_ARCHIVE_DEST_1='LOCATION=/oracle/app/flash_recovery_area/YEYEAI/archivelog VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=standby'

LOG_ARCHIVE_DEST_2='SERVICE=yeyeai LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=YEYEAI'

FAL_SERVER=yeyeai

FAL_CLIENT=standby

STANDBY_FILE_MANAGEMENT=AUTO

4、  修改主库的listener.ora文件

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = YEYEAI)

      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)

      (SID_NAME = YEYEAI)

    )

  )

 

LISTENER =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.1.14)(PORT = 1521))

  )

5、  修改主库的tnsnames.ora文件

YEYEAI =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST =10.1.1.14)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = YEYEAI)

    )

  )

STANDBY =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST =10.1.1.25)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = standby)

    )

  )

 

ORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

 

EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

    )

    (CONNECT_DATA =

      (SID = PL***tProc)

      (PRESENTATION = RO)

    )

  )

6、  修改从库的listener.ora文件

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (GLOBAL_DBNAME = STANDBY)

      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)

      (SID_NAME = STANDBY)

    )

  )

 

LISTENER =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.1.25)(PORT = 1521))

  )

7、  修改从库的tnsnames.ora文件

 

yeyeai =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.1.14)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = YEYEAI)

    )

  )

8、 主库和从库都启动监听：lsnrctl start

9、设置服务器为归档模式

alter database archivelog

设置主数据库为日志强制写状态

alter database force logging;

查看状态日志强制写状态为YES

select t.FORCE_LOGGING from v$database t

10．主库的数据用RMAN进行全备份：

 RMAN > connect target /

RMAN >backup full database include current controlfile for standby;

11．备份后将备份集传到从库（注意备份集的路径要相同）

主库：

   

从库：

12．在主库执行RMAN恢复备库数据：

RMAN > connect auxiliary sys/aiyeye@slave

RMAN > duplicate target database for standby nofilenamecheck;

完毕后从库回自动到mount状态

13．在从库执行自动恢复状态

alter database recover managed standby database disconnect from session;

14．主库执行：

    select process from v$managed_standby;

查看进程，看有没有LNS进程，如果没有

 

测试数据库同步成功
