准备工作:
主库启用归档
在所有系统上安装 oralce 11g 软件
备库创建必要的目录
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
*.audit_file_dest= /u2/oracle/admin/matrix/adump
*.audit_trail= db
*.compatible= 11.2.0.0.0
*.control_files= /oradata/matrix/control01.ctl , /u2/oracle/fast_recovery_area/matrix/control02.ctl
*.db_block_size=8192

*.memory_target=419430400
*.open_cursors=300
*.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_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

*.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;
