二：安装备库oracle软件：
安装操作系统：略
修改主机名和hosts文件：
[root@dg ~]# more /etc/hosts # Do not remove the following line, or various programs # that require network functionality will fail. 127.0.0.1localhost.localdomain localhost ::1localhost6.localdomain6 localhost6 172.16.30.228dg
4.修改系统参数：
[root@dg ~]# cat >>/etc/sysctl.conf <fs.file-max = 6815744 > kernel.sem = 250 32000 100 128 > kernel.shmmni = 4096 > kernel.shmall = 1073741824 > kernel.shmmax = 4398046511104 > net.core.rmem_default = 262144 > net.core.rmem_max = 4194304 > net.core.wmem_default = 262144 > net.core.wmem_max = 1048576 > fs.aio-max-nr = 1048576 > net.ipv4.ip_local_port_range = 9000 65500 > eof
[root@dg ~]# sysctl -p net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 2 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 68719476736 kernel.shmall = 4294967296 fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500
5.修改资源限制配置文件：
[root@dg ~]# cat >>/etc/security/limits.conf <grid soft nofile 1024 > grid hard nofile 65536 > grid soft nproc 2047 > grid hard nproc 16384 > grid soft stack 10240 > grid hard stack 32768 > oracle soft nofile 1024 > oracle hard nofile 65536 > oracle soft nproc 2047 > oracle hard nproc 16384 > oracle soft stack 10240 > oracle hard stack 32768 > eof [root@dg ~]# tail -20 /etc/security/limits.conf grid soft nofile 1024 grid hard nofile 65536 grid soft nproc 2047 grid hard nproc 16384 grid soft stack 10240 grid hard stack 32768 oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 3276
6.配置yum源并安装依赖包：
[root@dg ~]# cat /etc/yum.repos.d/local.repo [Redhat6] name= Enterpress6.5 baseurl=file:///mnt/Server enabled=1 gpgcheck=0 [root@dg ~]# mount /dev/sr0 /mnt/ mount: block device /dev/sr0 is write-protected, mounting read-only
yum -y install binutils compat-libstdc++-33elfutils-libelf \ elfutils-libelf-devel elfutils-libelf-devel-static gccgcc-c++ glibc glibc-common \ glibc-devel kernel-headers ksh libaio libaio-devel libgcclibgomp libstdc++ libstdc++-devel \ make numactl-devel sysstatunixODBC unixODBC-devel pdksh
7.建立用户，用户组，安装目录：
[root@dg ~]# /usr/sbin/groupadd -g 54321 oinstall [root@dg ~]# /usr/sbin/groupadd -g 54322 dba [root@dg ~]# /usr/sbin/groupadd -g 54323 oper [root@dg ~]# /usr/sbin/groupadd -g 54324 backupdba [root@dg ~]# /usr/sbin/groupadd -g 54325 dgdba [root@dg ~]# /usr/sbin/groupadd -g 54327 asmdba [root@dg ~]# /usr/sbin/groupadd -g 54328 asmoper [root@dg ~]# /usr/sbin/groupadd -g 54329 asmadmin [root@dg ~]# /usr/sbin/useradd -u 54321 -g oinstall -G asmadmin,asmdba,asmoper,dba grid [root@dg ~]# /usr/sbin/useradd -u 54322 -g oinstall -G dba,backupdba,dgdba,asmadmin,asmdba orac [root@dg ~]# passwd grid Changing password for user grid. New UNIX password: BAD PASSWORD: it is too short Retype new UNIX password: Sorry, passwords do not match. New UNIX password: BAD PASSWORD: it is too short Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@dg ~]# passwd oracle Changing password for user oracle. New UNIX password: BAD PASSWORD: it is based on a dictionary word Retype new UNIX password: passwd: all authentication tokens updated successfully. [root@dg ~]# mkdir -p /u01/app/grid [root@dg ~]# mkdir -p /u01/app/11.2.0/grid [root@dg ~]# mkdir -p /u01/app/oracle/product/11.2.0/db_1 [root@dg ~]# chown -R grid.oinstall /u01 [root@dg ~]# chown -R oracle.oinstall /u01/app/oracle [root@dg ~]# chmod -R 775 /u01
8.配置环境变量：
[root@dg ~]# cat >>/home/grid/.bash_profile <eof [root@dg ~]# source /home/grid/.bash_profile [root@dg ~]# cat >>/home/oracle/.bash_profile < 9.配置ASM磁盘：
[root@dg Server]# rpm -ivh oracleasm-support-2.1.7-1.el5.x86_64.rpm warning: oracleasm-support-2.1.7-1.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159 Preparing... ########################################### [100%] 1:oracleasm-support ########################################### [100%] [root@dg Server]# rpm -ivh oracleasm-2.6.18-308.el5-2.0.5-1.el5.x86_64.rpm warning: oracleasm-2.6.18-308.el5-2.0.5-1.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159 Preparing... ########################################### [100%] 1:oracleasm-2.6.18-308.el########################################### [100%] [root@dg Server]# cd [root@dg ~]# rpm -ivh oracleasmlib-2.0.4-1.el5.x86_64.rpm warning: oracleasmlib-2.0.4-1.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159 Preparing... ########################################### [100%] 1:oracleasmlib ########################################### [100%][root@dg ~]# /etc/init.d/oracleasm configure -i Configuring the Oracle ASM library driver.

二.配置DG:（主库实例PHUB，备库实例MECBS）
1.备库配置静态监听：（）
在grid的监听文件中加入：
SID_LIST_LISTENER= (SID_LIST= (SID_DESC= (GLOBAL_DBNAME=MECBS) (ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1) (SID_NAME=MECBS) ) )重启监听：
Service "MECBS" has 1 instance(s). Instance "MECBS", status UNKNOWN, has 1 handler(s) for this service... The command completed successfully2.配置主库和备库的tns：（注意把主机名换成IP）
PHUB = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.30.228)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = PHUB) ) ) MECBS = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = dg)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = MECBS) ) )用tnsping验证：
[oracle@cwogg admin]$ tnsping PHUB TNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 22-SEP-2015 16:20:37 Copyright (c) 1997, 2013, Oracle. All rights reserved. Used parameter files: /u01/app/oracle/product/11.2.0/db_1/network/admin/sqlnet.ora Used TNSNAMES adapter to resolve the alias Attempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = cwogg)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = PHUB))) OK (50 msec)3.编辑备库参数文件：
[oracle@dg dbs]$ more initMECBS.ora *.db_name='PHUB' 这里和主库一样的4.拷贝密码文件：
[oracle@cwogg dbs]$ scp orapwPHUB 172.16.30.228:/u01/app/oracle/product/11.2.0/db_1/dbs/orapwMECBS oracle@172.16.30.228's password: orapwPHUB100% 1536 1.5KB/s 00:00
5.编辑duplicate.sql
[oracle@cwogg ~]$ vim duplicate.sql duplicate target database for standby from active database nofilenamecheck DORECOVER spfile set service_names='MECBS' set db_unique_name='MECBS' set log_archive_config='dg_config=(MECBS,PHUB)' set log_archive_dest_1='location=+DATA VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=MECBS' set log_archive_dest_2='SERVICE=PHUB LGWR SYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=PHUB' set standby_file_management='AUTO' set diagnostic_dest='/u01/app/oracle' set audit_file_dest='/u01/app/oracle/admin/MECBS/adump' set fal_server='PHUB' set fal_client='MECBS' set control_files='+DATA/mecbs/controlfile/control01.ctl','+DATA/mecbs/controlfile/control02.ctl' set cluster_database='false' #set DB_FILE_NAME_CONVERT='' 数据库文件路径不一样需要详细写出来 #set LOG_FILE_NAME_CONVERT='' set db_create_file_dest='+DATA' set db_recovery_file_dest='+DATA' set db_recovery_file_dest_size='4G';6.启动备库nomount：
