利用ORACLE 11g 新特性创建物理备库

准备工作：

1. 主库启用归档
   

2. 在所有系统上安装oralce 11g软件

3. 备库创建必要的目录

4. 创建监听，配置tnsname文件

第一步：

将主库的密码文件cp一份到备库中

第二步：

主备库的参数文件修改：

主库参数文件如：

matrix.__db_cache_size=83886080

matrix.__java_pool_size=4194304

matrix.__large_pool_size=4194304

matrix.__oracle_base='/u2/oracle'#ORACLE_BASE set from environment

matrix.__pga_aggregate_target=176160768

matrix.__sga_target=243269632

matrix.__shared_io_pool_size=0

matrix.__shared_pool_size=138412032

matrix.__streams_pool_size=0

*.db_name='matrix'

*.db_recovery_file_dest='/u2/oracle/fast_recovery_area'

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.undo_tablespace='UNDOTBS1'

*.db_unique_name='matrix'

*.log_archive_config='dg_config=(matrix,matrixdg)'

*.log_archive_dest_1='location=/oradata/arch/matrix'

*.log_archive_dest_2='service=matrixdg lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=matrixdg'

*.log_archive_dest_state_1=enable

*.log_archive_dest_state_2=enable

*.standby_file_management='auto'

*.fal_server='matrixdg'

*.fal_client='matrix'

*.db_file_name_convert='/oradata/matrixdg','/oradata/matrix'

*.log_file_name_convert='/oradata/arch/matrixdg','/oradata/matrix'

备库参数文件如：

*.audit_file_dest='/u2/oracle/admin/matrixdg/adump'

*.audit_trail='db'

*.compatible='11.2.0.0.0'

*.control_files='/oradata/matrixdg/control01.ctl','/u2/oracle/fast_recovery_area/matrixdg/control02.ctl'

*.db_block_size=8192

*.db_domain=''

*.db_name='matrix'

*.log_archive_dest_1='location=/oradata/arch/matrixdg'

*.log_archive_dest_2='service=matrix lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=matrix'

*.log_archive_dest_state_1=enable

*.log_archive_dest_state_2=enable

*.standby_file_management='manual'

*.fal_server='matrix'

*.fal_client='matrixdg'

*.db_file_name_convert='/oradata/matrix','/oradata/matrixdg'

*.log_file_name_convert='/oradata/arch/matrix','/oradata/arch/atrixdg'

第四步：

将备库启动到nomount状态

SQL> startup nomount

第五步：

RMAN>connect target sys/oracle@matrix;

RMAN>connect target sys/oracle@matrixdg;

RMAN>duplicate target database for standby from active database;

第六步：

备为中创建standby redo logfile

SQL>alter database add standby logfile '<PATH>' size 50M;

第七步：

备为中启动日志应用

SQL>alter database recover managed standby database using current logfile disconnect;
