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

*.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;
