1，软件安装前基础部署
（两台做同样操作）
1.1，关闭selinux和防火墙
因为centos7里面没有/etc/sysconfig/iptables这个配置文件所以我们首先用yum安装建立一个
[root@adg ~]# yum install -y iptables &&
yum -y install iptables-services然后在iptables里加上一条防火墙规则，到后面的tnsping会用的到，不加的话可能会tnsping不通
在最后加上-A INPUT -m state --state NEW -m tcp -p tcp --dport 1521-j ACCEPT
[root@adg ~]# cat /etc/sysconfig/iptables *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibiteda -A INPUT -m state --state NEW -m tcp -p tcp --dport 1521-j ACCEPT COMMIT
关闭selinux和防火墙
[root@adg ~]# setenforce 0 && sed -i "s/^SELINUX=.*/SELINUX=disabled/g" /etc/selinux/config && iptables -F && systemctl stop iptables.services && chkconfig iptables off setenforce: SELinux is disabled
1.2,修改时区，否则可能会主备不同步
查看当前时区
[root@adg ~]# date Wed Oct 30 22:17:35 EDT 2019
执行tzselect命令按提示更换时区，依次选择5-Asia，9-China,1-Beijing Time.
[root@adg ~]# tzselect Please identify a location so that time zone rules can be set correctly. Please select a continent or ocean. 1) Africa 2) Americas 3) Antarctica 4) Arctic Ocean 5) Asia 6) Atlantic Ocean 7) Australia 8) Europe 9) Indian Ocean 10) Pacific Ocean 11) none - I want to specify the time zone using the Posix TZ format. #? 5 Please select a country. 1) Afghanistan 18) Israel 35) Palestine 2) Armenia 19) Japan 36) Philippines 3) Azerbaijan 20) Jordan 37) Qatar 4) Bahrain 21) Kazakhstan 38) Russia 5) Bangladesh 22) Korea (North) 39) Saudi Arabia 6) Bhutan 23) Korea (South) 40) Singapore 7) Brunei 24) Kuwait 41) Sri Lanka 8) Cambodia 25) Kyrgyzstan 42) Syria 9) China 26) Laos 43) Taiwan 10) Cyprus 27) Lebanon 44) Tajikistan 11) East Timor 28) Macau 45) Thailand 12) Georgia 29) Malaysia 46) Turkmenistan 13) Hong Kong 30) Mongolia 47) United Arab Emirates 14) India 31) Myanmar (Burma) 48) Uzbekistan 15) Indonesia 32) Nepal 49) Vietnam 16) Iran 33) Oman 50) Yemen 17) Iraq 34) Pakistan #? 9 Please select one of the following time zone regions. 1) Beijing Time 2) Xinjiang Time #? 1 The following information has been given: China Beijing Time Therefore TZ='Asia/Shanghai' will be used. Local time is now: Thu Oct 31 10:19:14 CST 2019. Universal Time is now: Thu Oct 31 02:19:14 UTC 2019. Is the above information OK? 1) Yes 2) No #? 1 You can make this change permanent for yourself by appending the line TZ='Asia/Shanghai'; export TZ to the file '.profile' in your home directory; then log out and log in again. Here is that TZ value again, this time on standard output so that you can use the /bin/tzselect command in shell scripts: Asia/Shanghai 配置全局环境变量，添加export TZ=‘Asia/Shanghai’ [root@adg ~]# vim /etc/profile export TZ='Asia/Shanghai' [root@adg ~]# source /etc/profile [root@adg ~]# date Thu Oct 31 10:22:03 CST 2019
1.3,配置yum源
设置163和epel的yum源
[root@adg ~]# setenforce 0 > /dev/null 2>&1 [root@adg ~]# cp /etc/sysconfig/iptables /etc/sysconfig/iptables`date +%F_%T` [root@adg ~]# cp /etc/yum.conf /etc/yum.confbak`date +%F_%T` [root@adg ~]# echo 'exclude=kernel* exclude=centos-release*' >> /etc/yum.conf && grep exclude /etc/yum.conf && mkdir -p /tmp/repobak && rm -rf /tmp/repobak/* && cd /etc/yum.repos.d/ && mv -f * /tmp/repobak/ > /dev/null 2>&1 [root@adg ~]# curl -o /etc/yum.repos.d/CentOS6-Base-163.repo http://mirrors.163.com/.help/CentOS6-Base-163.repo [root@adg ~]# mv -f /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup > /dev/null 2>&1 [root@adg ~]# mv -f /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup > /dev/null 2>&1 [root@adg ~]# curl -o /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo [root@adg ~]# rpm --import /etc/pki/rpm-gpg/RPM* && yum clean all && yum makecache && yum groupinfo 'Development tools' && yum groupinstall -y 'Development tools' && yum install wget vim man rsync openssh-clients openssl -y && ls -l && cd ~
1.4,安装依赖包
[root@adg ~]# yum install binutils compat-libstdc* elfutils-libelf elfutils-libelf-devel gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++-devel libgomp make numactl numactl-devel sysstat -y [root@adg ~]# yum install unixODBC unixODBC-devel -y #pdksh需要使用rpm安装，把包放到/tmp目录下 [root@adg ~]# yum -y install lrzsz [root@adg ~]# rpm -ivh pdksh-5.2.14-1.i386.rpm --nodeps
1.5,配置主机名(HOST解析)
主：
[root@adg ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.25.44 adg 192.168.25.45 dg
备：
[root@dg ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.25.45 dg 192.168.25.44 adg
1.6，配置内核参数
[root@adg ~]# cp /etc/sysctl.conf /etc/sysctl.conf.bak [root@adg ~]# echo 'net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 8589934591 kernel.shmall = 2097152 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576' > /etc/sysctl.conf 执行/sbin/sysctl -p使之生效 [root@adg ~]# /sbin/sysctl -p
---如果有下列报错
sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-ip6tables: No such file or directory sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-iptables: No such file or directory sysctl: cannot stat /proc/sys/net/bridge/bridge-nf-call-arptables: No such file or directory
---执行下面命令（没有报错请忽略（下面解决方法适用于centos7版本，centos6我试过不行，解决不了））
[root@adg ~]# modprobe br_netfilter [root@adg ~]# ls /proc/sys/net/bridge/ bridge-nf-call-arptables bridge-nf-call-iptables bridge-nf-filter-vlan-tagged bridge-nf-call-ip6tables bridge-nf-filter-pppoe-tagged bridge-nf-pass-vlan-input-dev [root@adg ~]# /sbin/sysctl -p net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-arptables = 0 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 8589934591 kernel.shmall = 2097152 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 [root@adg ~]# egrep -v '^#|^$' /etc/sysctl.conf | wc -l 22
参数说明
kernel.shmmax： 64位linux系统：可取的最大值为物理内存值-1byte，建议值为多于物理内存的一半，一般取值大于SGA_MAX_SIZE即可，可以取物理内存-1byte。例如，如果为12GB物理内存，可取128*1024*1024*1024-1=12884901887，SGA肯定会包含在单个共享内存段中。128GB对应的是137438953471。 kernel.shmall： 该参数控制可以使用的共享内存的总页数。Linux共享内存页大小为4KB,共享内存段的大小都是共享内存页大小的整数倍。一个共享内存段的最大大小是16G，那么需要共享内存页数是16GB/4KB=16777216KB /4KB=4194304（页）。 即16GB对应4194304，8GB对应2097152，128GB对应33554432 net.ipv4.ip_forward = 0 #不变 net.ipv4.conf.default.rp_filter = 1 #不变 net.ipv4.conf.default.accept_source_route = 0 #不变 kernel.sysrq = 0 #不变 kernel.core_uses_pid = 1 #不变 net.ipv4.tcp_syncookies = 1 #不变 net.bridge.bridge-nf-call-ip6tables = 0 #不变 net.bridge.bridge-nf-call-iptables = 0 #不变 net.bridge.bridge-nf-call-arptables = 0 #不变 kernel.msgmnb = 65536 #不变 kernel.msgmax = 65536 #不变 kernel.shmmax = 4294967295 #变 note:4*1024*1024*1024-1=4294967295 共享内存段的最大尺寸，需要小于SGA MAX SIZE，大小为shmall*页大小（4K）； kernel.shmall = 2097152 #变note:4*1024*1024/4K*2=2097152，两倍, 1倍实际不够，控制共享内存页数 fs.aio-max-nr = 1048576 #新增 异步I/O请求数目 fs.file-max = 6815744 #新增 一个进程可以打开的文件句柄的最大数量 kernel.shmmni = 4096 #新增 共享内存段的最大数量，ipcs -sa kernel.sem = 250 32000 100 128 #新增 设置的信号量 net.ipv4.ip_local_port_range = 9000 65500 #新增 专用服务器模式下与用户进程通信时分配给用户的端口区间 net.core.rmem_default = 262144 #新增 默认接收缓冲区大小 net.core.rmem_max = 4194304 #新增 接收缓冲区最大值 net.core.wmem_default = 262144 #新增 默认发送缓冲区大小 net.core.wmem_max = 1048586 #新增 默认发送缓冲区大小
1.7，配置资源限制
soft是指当前系统设置生效的值，而hard表明系统中所能设定的最大值，nofile是指文件句柄数，nproc是指进程数，
[root@adg ~]# cp /etc/security/limits.conf /etc/security/limits.conf.bak [root@adg ~]# sed -i.bak 's/1024/102400/' /etc/security/limits.d/20-nproc.conf [root@adg ~]# ulimit -u 102400 [root@adg ~]# echo 'session required pam_limits.so' >> /etc/pam.d/login [root@adg ~]# echo ' oracle soft nproc 16000 oracle hard nproc 16384 oracle soft nofile 60000 oracle hard nofile 65536 oracle soft stack 20480 oracle hard stack 20480 * soft memlock unlimited * hard memlock unlimited' >> /etc/security/limits.conf
参数说明
oracle soft nproc 16000 #oracle要求最小为2047 oracle hard nproc 16384 #--进程的最大数目，对oracle用户生效 oracle soft nofile 60000 #oracle要求最小为1024 oracle hard nofile 65536 #--打开文件的最大数目，对oracle用户生效 oracle soft stack 10240 oracle hard stack 10240 * soft memlock unlimited * hard memlock unlimited #--最大锁定内存地址空间，对所有用户生效
1.8，创建用户和组，并创建密码
[root@adg ~]# groupadd oinstall [root@adg ~]# groupadd dba [root@adg ~]# useradd -g oinstall -G dba oracle [root@adg ~]# id oracle uid=1000(oracle) gid=1000(oinstall) groups=1000(oinstall),1001(dba) [root@adg ~]# echo "oracle" | passwd --stdin oracle Changing password for user oracle. passwd: all authentication tokens updated successfully.
1.9，创建安装oracle软件所需要的安装目录
[root@adg ~]# mkdir -p /data/app/oracle [root@adg ~]# mkdir -p /data/app/oraInventory [root@adg ~]# chown -R oracle:oinstall /data/ [root@adg ~]# chmod -R 775 /data/
1.10，配置root和oracle的环境变量
root用户：
[root@adg ~]# cat >> /root/.bash_profile << EOF export ORACLE_BASE=/data/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.4/db_1 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:$GGS_HOME export TNS_ADMIN=$ORACLE_HOME/network/admin/ EOF

1.11，上传oracle安装包和rlwrap软件包并解压
oracle用户上传，上传至/tmp目录
[root@adg ~]# su - oracle Last login: Tue Oct 29 22:58:03 EDT 2019 on pts/0 [oracle@adg ~]$ cd /tmp/ [oracle@adg tmp]$ ls p13390677_112040_Linux-x86-64_1of7.zip p13390677_112040_Linux-x86-64_2of7.zip pdksh-5.2.14-1.i386.rpm rlwrap-0.42.tar.gz [oracle@adg database]$ unzip p13390677_112040_Linux-x86-64_1of7.zip && unzip p13390677_112040_Linux-x86-64_2of7.zip && chown -R oracle:oinstall /tmp/database/ && chmod -R 775 /tmp/database/ && cd /tmp/database && ll 。。。。。。。。。。。。。。。。。。。。。。。 。。。。。。。。。。。。。。。。。。。。。。。。 total 44 drwxrwxr-x 4 oracle oinstall 248 Aug 27 2013 install -rwxrwxr-x 1 oracle oinstall 30016 Aug 27 2013 readme.html drwxrwxr-x 2 oracle oinstall 61 Aug 27 2013 response drwxrwxr-x 2 oracle oinstall 34 Aug 27 2013 rpm -rwxrwxr-x 1 oracle oinstall 3267 Aug 27 2013 runInstaller drwxrwxr-x 2 oracle oinstall 29 Aug 27 2013 sshsetup drwxrwxr-x 14 oracle oinstall 4096 Aug 27 2013 stage -rwxrwxr-x 1 oracle oinstall 500 Aug 27 2013 welcome.html
root用户安装rlwrap
[root@adg ~]# cd /tmp/ [root@adg tmp]# yum -y install readline* && tar -zxvf rlwrap-0.42.tar.gz && cd rlwrap-0.42 && ./configure && make && make install
2，使用静默方式安装oracle
安装包解压后在/database/response目录下有三个rsp文件，用来作为静默安装时的应答文件
三个文件的作用分别是：
db_install.rsp:安装应答
dbca.rsp：创建数据库应答
netca.rsp：建立监听、本地服务名等网络设置的应答
2.1，配置db_install.rsp
注意这里主备不同的是要修改自己得主机名：ORACLE_HOSTNAME=XXX
主备的SID都是orcl
[root@adg ~]# su - oracle Last login: Wed Oct 30 02:41:56 EDT 2019 on pts/0 [oracle@adg ~]$ cd /tmp/database/response/ [oracle@adg response]$ cp db_install.rsp db_install.rsp.bak cat > /tmp/database/response/db_install.rsp << EOF oracle.install.responseFileVersion=/oracle/install/rspfmt_dbinstall_response_schema_v11_2_0 oracle.install.option=INSTALL_DB_SWONLY ORACLE_HOSTNAME=adg UNIX_GROUP_NAME=oinstall INVENTORY_LOCATION=/data/app/oraInventory SELECTED_LANGUAGES=en,zh_CN,th,zh_TW ORACLE_HOME=/data/app/oracle/product/11.2.0.4/db_1 ORACLE_BASE=/data/app/oracle oracle.install.db.InstallEdition=EE oracle.install.db.EEOptionsSelection=true oracle.install.db.optionalComponents=oracle.rdbms.partitioning:11.2.0.4.0,oracle.oraolap:11.2.0.4.0,oracle.rdbms.dm:11.2.0.4.0,oracle.rdbms.dv:11.2.0.4.0,oracle.rdbms.lbac:11.2.0.4.0,oracle.rdbms.rat:11.2.0.4.0 oracle.install.db.DBA_GROUP=dba oracle.install.db.OPER_GROUP=oinstall oracle.install.db.CLUSTER_NODES= oracle.install.db.isRACOneInstall= oracle.install.db.racOneServiceName= oracle.install.db.config.starterdb.type=GENERAL_PURPOSE oracle.install.db.config.starterdb.globalDBName=orcl oracle.install.db.config.starterdb.SID=orcl oracle.install.db.config.starterdb.characterSet=AL32UTF8 oracle.install.db.config.starterdb.memoryOption=true oracle.install.db.config.starterdb.memoryLimit= oracle.install.db.config.starterdb.installExampleSchemas=false oracle.install.db.config.starterdb.enableSecuritySettings=true oracle.install.db.config.starterdb.password.ALL=oracle oracle.install.db.config.starterdb.password.SYS=oracle oracle.install.db.config.starterdb.password.SYSTEM=oracle oracle.install.db.config.starterdb.password.SYSMAN=oracle oracle.install.db.config.starterdb.password.DBSNMP= oracle.install.db.config.starterdb.control=DB_CONTROL oracle.install.db.config.starterdb.gridcontrol.gridControlServiceURL= oracle.install.db.config.starterdb.automatedBackup.enable=false oracle.install.db.config.starterdb.automatedBackup.osuid= oracle.install.db.config.starterdb.automatedBackup.ospwd= oracle.install.db.config.starterdb.storageType= oracle.install.db.config.starterdb.fileSystemStorage.dataLocation= oracle.install.db.config.starterdb.fileSystemStorage.recoveryLocation= oracle.install.db.config.asm.diskGroup= oracle.install.db.config.asm.ASMSNMPPassword= MYORACLESUPPORT_USERNAME= MYORACLESUPPORT_PASSWORD= SECURITY_UPDATES_VIA_MYORACLESUPPORT= DECLINE_SECURITY_UPDATES=true PROXY_HOST= PROXY_PORT= PROXY_USER= PROXY_PWD= PROXY_REALM= COLLECTOR_SUPPORTHUB_URL= oracle.installer.autoupdates.option=SKIP_UPDATES oracle.installer.autoupdates.downloadUpdatesLoc= AUTOUPDATES_MYORACLESUPPORT_USERNAME= AUTOUPDATES_MYORACLESUPPORT_PASSWORD= EOF

2.3，执行脚本
root用户执行下面两个脚本
[oracle@adg response]$ su - root Password: Last login: Wed Oct 30 02:59:26 EDT 2019 on pts/0 [root@adg ~]# sh /data/app/oraInventory/orainstRoot.sh Changing permissions of /data/app/oraInventory. Adding read,write permissions for group. Removing read,write,execute permissions for world. Changing groupname of /data/app/oraInventory to oinstall. The execution of the script is complete. [root@adg ~]# sh /data/app/oracle/product/11.2.0.4/db_1/root.sh Check /data/app/oracle/product/11.2.0.4/db_1/install/root_adg_2019-10-30_04-36-14.log for the output of root script
3，配置静态监听
HSOT要根据实际的主机名进行修改
3.1，配置监听文件
主：
[root@adg ~]# su - oracle Last login: Wed Oct 30 04:04:07 EDT 2019 on pts/0 [oracle@adg ~]$ cd $ORACLE_HOME/network/admin [oracle@adg admin]$ ll total 4 drwxr-xr-x 2 oracle oinstall 64 Oct 30 04:24 samples -rw-r--r-- 1 oracle oinstall 381 Dec 17 2012 shrept.lst
[oracle@adg admin]$ echo ' SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = orcl) (ORACLE_HOME = /data/app/oracle/product/11.2.0.4/db_1) (SID_NAME = orcl) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = adg)(PORT = 1521)) ) ) ADR_BASE_LISTENER = /data/app/oracle' > listener.ora
备：
[root@adg ~]# su - oracle Last login: Wed Oct 30 04:04:07 EDT 2019 on pts/0 [oracle@adg ~]$ cd $ORACLE_HOME/network/admin [oracle@dg admin]$ echo ' SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = orcl) (ORACLE_HOME = /data/app/oracle/product/11.2.0.4/db_1) (SID_NAME = orcl) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = dg)(PORT = 1521)) ) ) ADR_BASE_LISTENER = /data/app/oracle' > listener.ora
3.2，配置网络服务名文件
主备配置一样，只需要修改一下主机名就行
主：
[oracle@adg admin]$ echo ' ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = adg)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) (SERVER = DEDICATED) ) ) ' > tnsnames.ora
备：
[oracle@dg admin]$ echo ' ORCL = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = dg)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) (SERVER = DEDICATED) ) ) ' > tnsnames.ora
启动监听程序
[oracle@adg admin]$ lsnrctl start && lsnrctl reload && tnsping orcl && lsnrctl status Used TNSNAMES adapter to resolve the alias Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = adg)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = orcl) (SERVER = DEDICATED))) OK (0 msec) LSNRCTL for Linux: Version 11.2.0.4.0 - Production on 30-OCT-2019 21:49:37 Copyright (c) 1991, 2013, Oracle.

3.3，查看监听程序是否启动
[oracle@adg admin]$ netstat -luntp | grep tnslsnr (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp6 0 0 :::1521 :::* LISTEN 6594/tnslsnr
4，静默安装数据库（创建实例）
这里只需主库创建库（实例），备库不要创建，备库开启监听就行
4.1，配置响应文件dbca.rsp
[oracle@adg ~]$ mkdir -p /data/app/oracle/oradata [oracle@adg ~]$ mkdir -p /data/app/oracle/flash_recovery_area [oracle@adg ~]$ cd /tmp/database/response/ [oracle@adg response]$ cp dbca.rsp dbca.rsp.bak [oracle@adg response]$ cat > /tmp/database/response/dbca.rsp << EOF [GENERAL] RESPONSEFILE_VERSION = "11.2.0" OPERATION_TYPE = "createDatabase" [CREATEDATABASE] GDBNAME = "orcl" SID = "orcl" TEMPLATENAME = "General_Purpose.dbc" SYSPASSWORD = "oracle" SYSTEMPASSWORD = "oracle" DATAFILEDESTINATION = /data/app/oracle/oradata RECOVERYAREADESTINATION=/data/app/oracle/flash_recovery_area CHARACTERSET = "AL32UTF8" [CONFIGUREDATABASE] SYSDBAUSERNAME = "sys" EOF
dbca.rsp文件参数说明：
RESPONSEFILE_VERSION = "11.2.0" #不能更改 OPERATION_TYPE = "createDatabase" #不变 默认即可 GDBNAME = "orcl" #数据库的名字，随便怎么改，不影响，自定义 比如"oracle11g.com" SID = "orcl" #对应的实例名字instance_name，随便怎么改，不影响，自定义 比如"oracle11g.com" TEMPLATENAME = "General_Purpose.dbc" #不变 默认即可 建库用的模板文件 SYSPASSWORD = "oracle" #SYS管理员密码 自定义 SYSTEMPASSWORD = "oracle" #SYSTEM管理员密码 自定义 DATAFILEDESTINATION = /data/app/oracle/oradata #数据文件存放目录 可自定义如/data目录但用户和组要是oracle:oinstall即mkdir /data ; chown -R oracle:oinstall /data ; chmod -R 775 /data; 当然此项默认是$ORACLE_BASE/oradata 此项本来是注释掉的，而$ORACLE_BASE/oradata就是/data/app/oracle/oradata，故此项可不用动，即保持注释掉即也可； RECOVERYAREADESTINATION=/data/app/oracle/flash_recovery_area #恢复数据存放目录 闪回区 可自定义 CHARACTERSET = "AL32UTF8" #字符集，重要!!! 建库后一般不能更改，所以建库前要确定清楚，选AL32UTF8比较合适； NATIONALCHARACTERSET= "AL16UTF16" #最好还是保持默认的"AL16UTF16"，这里我选的UTF8可能出现了后面的PLSQL中文乱码； #MEMORYPERCENTAGE = "40" #服务器物理内存分配给oracle的内存比例，这里先不选 #TOTALMEMORY = "3500" # //物理内存的60%左右，分配给oracle的总内存3500MB，可自行设定 或者注释不选因为oracle会自行管理； #-----------------------*** End of CREATEDATABASE section ***------------------------ SOURCEDB = "myhost:1521:orcl" #End of CREATEDATABASE sectio后面的很多没有注释掉的选项不用管。
4.2，执行响应文件dbca.rsp
oracle用户执行，使用-responseFile参数后面必须跟绝对路径
[oracle@adg response]$ dbca -silent -responseFile /tmp/database/response/dbca.rsp Copying database files 1% complete 。。。。。。 。。。。。。 100% complete Look at the log file "/data/app/oracle/cfgtoollogs/dbca/orcl/orcl.log" for further details. [oracle@adg response]$
4.3，查看oracle进程
[oracle@adg ~]$ ps -ef | grep ora_| grep -v grep |wc -l 36 [oracle@adg ~]$ ps -ef | grep ora_| grep -v grep oracle 6654 1 0 22:00 ? 00:00:00 ora_pmon_DBUA0030506 oracle 6656 1 0 22:00 ? 00:00:00 ora_psp0_DBUA0030506 oracle 6658 1 0 22:00 ? 00:00:02 ora_vktm_DBUA0030506 oracle 6662 1 0 22:00 ? 00:00:00 ora_gen0_DBUA0030506 oracle 6664 1 0 22:00 ? 00:00:00 ora_diag_DBUA0030506 oracle 6666 1 0 22:00 ? 00:00:00 ora_dbrm_DBUA0030506 oracle 6668 1 0 22:00 ? 00:00:00 ora_dia0_DBUA0030506 oracle 6670 1 0 22:00 ? 00:00:00 ora_mman_DBUA0030506 oracle 6672 1 0 22:00 ? 00:00:00 ora_dbw0_DBUA0030506 oracle 6674 1 0 22:00 ? 00:00:00 ora_lgwr_DBUA0030506 oracle 6676 1 0 22:00 ? 00:00:00 ora_ckpt_DBUA0030506 oracle 6678 1 0 22:00 ? 00:00:00 ora_smon_DBUA0030506 oracle 6680 1 0 22:00 ? 00:00:00 ora_reco_DBUA0030506 oracle 6682 1 0 22:00 ? 00:00:00 ora_mmon_DBUA0030506 oracle 6684 1 0 22:00 ? 00:00:00 ora_mmnl_DBUA0030506 oracle 7013 1 0 22:04 ? 00:00:00 ora_pmon_orcl oracle 7015 1 0 22:04 ? 00:00:00 ora_psp0_orcl oracle 7017 1 0 22:04 ? 00:00:01 ora_vktm_orcl oracle 7021 1 0 22:04 ? 00:00:00 ora_gen0_orcl oracle 7023 1 0 22:04 ? 00:00:00 ora_diag_orcl oracle 7025 1 0 22:04 ? 00:00:00 ora_dbrm_orcl oracle 7027 1 0 22:04 ? 00:00:00 ora_dia0_orcl oracle 7029 1 0 22:04 ? 00:00:00 ora_mman_orcl oracle 7031 1 0 22:04 ? 00:00:00 ora_dbw0_orcl oracle 7033 1 0 22:04 ? 00:00:00 ora_lgwr_orcl oracle 7035 1 0 22:04 ? 00:00:00 ora_ckpt_orcl oracle 7037 1 0 22:04 ? 00:00:00 ora_smon_orcl oracle 7039 1 0 22:04 ? 00:00:00 ora_reco_orcl oracle 7041 1 0 22:04 ? 00:00:00 ora_mmon_orcl oracle 7043 1 0 22:04 ? 00:00:00 ora_mmnl_orcl oracle 7045 1 0 22:04 ? 00:00:00 ora_d000_orcl oracle 7047 1 0 22:04 ? 00:00:00 ora_s000_orcl oracle 7055 1 0 22:04 ? 00:00:00 ora_qmnc_orcl oracle 7073 1 0 22:04 ? 00:00:00 ora_cjq0_orcl oracle 7075 1 0 22:05 ? 00:00:00 ora_q000_orcl oracle 7077 1 0 22:05 ? 00:00:00 ora_q001_orcl #把oracle配置文件最后一行改为yes，/etc/oratab [oracle@adg ~]$ cat /etc/oratab .......................... orcl:/data/app/oracle/product/11.2.0.4/db_1:Y
5,开始搭建配置ADG
5.1，编辑修改网络服务名配置文件tnsnames.ora，
编辑修改网络服务名配置文件tnsnames.ora，要保证主库和备库的tnsnames.ora文件中的内容完全相同，可以修改后直接传给备库。
注意：配置文件中的oraclpri和orclsty一定要等于pfile文件中的dbuniquename，否则可能会无法同步

5.2，主备都要重启监听
[oracle@adg ~]$ lsnrctl stop ; lsnrctl start ; lsnrctl reload
[oracle@dg ~]$ lsnrctl stop ; lsnrctl start ; lsnrctl reload5.3，配置完后，确保任意一端都可以tnsping通自己和对方

5.4，如果tnsping不通
如果tnsping不通，报如下错误
TNS-12543: TNS:destination host unreachable报错原因是1521的端口没有开放
解决方法：
（不确定是否都可以解决，但是我确实用这个解决了）
在/etc/sysconfig/iptables 这个配置文件里添加一条开放1521端口的策略
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1521-j ACCEPT
在进目录的时候会发现，centos7里并没有这个文件目录，所以我们需要安装iptables，iptables-services
执行下面命令
[root@adg ~]# systemctl stop firewalld [root@adg ~]# systemctl mask firewalld Created symlink from /etc/systemd/system/firewalld.service to /dev/null. [root@adg ~]# yum install -y iptables && yum -y install iptables-services
然后再添加下面的策略
用root用户添加
-A INPUT -m state --state NEW -m tcp -p tcp --dport 1521 -j ACCEPT
添加完成之后，重启防火墙
[root@adg ~]# cat /etc/sysconfig/iptables # sample configuration for iptables service # you can edit this manually or use system-config-firewall # please do not ask us to add additional ports/services to this default configuration *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibiteda -A INPUT -m state --state NEW -m tcp -p tcp --dport 1521 -j ACCEPT COMMIT [root@adg ~]# systemctl restart iptables #重启之后还是tnsping不通那就关闭一下防火墙 [root@adg ~]# systemctl stop iptables.service
6，主库配置
6.1，启用归档模式

6.3,拷贝密码文件
在Primary上创建密码文件（此步骤只在主库上做） ，注意如果主库的sys用户的密码更改了则密码文件也就会跟着变了则此时需要重启拷贝密码文件到备库的$ORACLE_HOME/dbs/目录才行。
注：经实测此步不用做也可以，因为密码文件本来就是有的，就是$ORACLE_HOME/dbs/orapworcl文件，而我们在拷贝参数文件到备库时会把整个$ORACLE_HOME/dbs/*拷贝到备库。
注意：主备库分别创建自己的密码文件好像有问题，备库的密码文件需要跟主库保持一致，否则导致日志传输不到备库。我最后是将主库的密码文件直接copy到备库的$ORACLE_HOME/dbs/目录即可，有的说拷贝到备库后把这个密码文件进行重命名后使用而实际不用重命名也可以。
主备库的密码文件要相同
[oracle@adg dbs]$ mkdir -p /data/app/rman_backup [oracle@adg dbs]$ pwd /data/app/oracle/product/11.2.0.4/db_1/dbs [oracle@adg dbs]$ cp orapworcl /data/app/rman_backup/
#正常都是有的，没有的话则创建一个密码文件即可，要保持主备密码文件名相同，否则同步可能出现错误
[oracle@adg ~]$ cd $ORACLE_HOME/dbs/ [oracle@adg ~]$ orapwd file=orapworcl password=oracle force=y
6.4，修改参数文件
6.4.1，生成pfile
SQL> sqlplus / as sysdba SQL> select status from v$instance; STATUS ------------ OPEN ----这里创建pfile是为了做一些主库参数的配置，并且还得拷贝到备库再次修改成备库的配置。 SQL> select open_mode,database_role,db_unique_name from v$database; OPEN_MODE DATABASE_ROLE DB_UNIQUE_NAME -------------------- ---------------- ------------------------------ READ WRITE PRIMARY orcl ---在主库上通过 SQL> select name from v$datafile; 查看对应的路径目录，用于*.db_file_name_convert SQL> select name from v$datafile; NAME -------------------------------------------------------------------------------- /data/app/oracle/oradata/orcl/system01.dbf /data/app/oracle/oradata/orcl/sysaux01.dbf /data/app/oracle/oradata/orcl/undotbs01.dbf /data/app/oracle/oradata/orcl/users01.dbf ---在主库上通过 SQL> select * from v$logfile; 查看对应的路径目录；用于*.log_file_name_convert SQL> select * from v$logfile; SQL> shutdown immediate; Database closed. Database dismounted. ORACLE instance shut down.
6.4.2 ，修改pfile
什么是pfile文件：初始化参数文件（Initialization Parameters Files），Oracle 9i之前，ORACLE一直采用PFILE方式存储初始化参数，该文件为文本文件。
什么是sfile文件：服务器参数文件（Server Parameter Files），从Oracle 9i开始，Oracle引入了SPFILE文件，该文件为二进制格式，不能通过手工修改。
区别：PFILE是文本文件的，而SPFILE是二进制格式的。PFILE文件可以用文本编辑器打开手工配置、而SPFILE不行，只能通过SQL命令在线修改。从操作系统上可以看到这两者的区别，初始化参数文件为ASCII文本文件，SPFILE为数据文件。

| 最大保护 | 最大可用 | 最大性能 | |
|---|---|---|---|
| 进程 | LGWR | LGWR | LGWR或ARCH |
| 网络传输模式 | SYNC | SYNC | LGWR时设置ASYNC |
| 磁盘写操作 | AFFIRM | AFFIRM | NOAFFIRM |
| 备用日志 | YES | 物理备用需要 | LGWR和物理备用时需要 |
| 备用库类型 | 物理Standby | 物理或逻辑 | 物理或逻辑 |
最大保护(maximize protection):最高级别的保护模式。primay上的事务在commit前必须确认redo已经传递到至少一个standby上，如果所有standby不可用，则primary会挂起。该模式能保证零数据丢失。对于最大保护和最高可用性模式，Standby数据库必须配置standby redo log，并且oracle推荐所有数据库都使用LGWR ASYNC模式传输。
如果是最大性能模式则写成LGWR ASYNC，如果是最大可用模式则写成LGWR SYNC AFFIRM；
6.4.3,生成spfile
什么是pfile文件：初始化参数文件（Initialization Parameters Files），Oracle 9i之前，ORACLE一直采用PFILE方式存储初始化参数，该文件为文本文件。
什么是sfile文件：服务器参数文件（Server Parameter Files），从Oracle 9i开始，Oracle引入了SPFILE文件，该文件为二进制格式，不能通过手工修改。
区别：PFILE是文本文件的，而SPFILE是二进制格式的。PFILE文件可以用文本编辑器打开手工配置、而SPFILE不行，只能通过SQL命令在线修改。从操作系统上可以看到这两者的区别，初始化参数文件为ASCII文本文件，SPFILE为数据文件。

6.5，配置最大性能模式
SQL> startup ORACLE instance started ---查看数据库的保护模式 SQL> select database_role,protection_mode,protection_level,open_mode from v$database; DATABASE_ROLE PROTECTION_MODE PROTECTION_LEVEL OPEN_MODE ---------------- -------------------- -------------------- -------------------- PRIMARY MAXIMUM PERFORMANCE MAXIMUM PERFORMANCE READ WRITE ---如果不是最大性能模式，则：（目前不需要修改） SQL> alter database set standby database to MAXIMIZE PERFORMANCE; Database altered. SQL> exit
说明如下：
DataGuard的三种数据保护模式：
（1）MAXIMIZE PROTECTION（最大保护模式）：alter database set standby database to MAXIMIZE PROTECTION;最大数据保护与无数据分歧，LGWR将同时传送到备用节点，在主节点事务确认之前，备用节点也必须完全收到日志数据。如果网络不好，引起LGWR不能传送数据，将引起严重的性能问题，导致主节点DOWN机。如果出现了什么故障导致 standby数据库不可用的话，primary 数据库会被shutdown。不适合在生产环境种应用。
（2）MAXIMIZE AVAILABILITY（最大可用模式）：alter database set standby database to maximize availability;无数据丢失模式，允许数据分歧，允许异步传送。正常情况下运行在最大保护模式，在主节点与备用节点的网络断开或连接不正常时，自动切换到最大性能模式，主节点的操作还是可以继续的。在网络不好的情况下有较大的性能影响。对数据库性能有影响，数据丢失相对最大性能模式要小。 不受备库影响。
（3）MAXIMIZE PERFORMANCE（最大性能模式）：alter database set standby database to MAXIMIZE PERFORMANCE; 最大性能模式是默认的保护模式。这种模式应当可以说是从8i继承过来的备用服务器模式，异步传送，无数据同步检查，可能丢失数据，但是能获得主节点的最大性能。在主数据库出现故障的情况下，可能有一些在主数据库上提交了的事务没有传输到备用数据库中。Primary不受影响备库影响。
6.6，创建standby的控制文件
在Primary上创建Standby Database的控制文件（此步骤只在主库上做） ，生成控制文件的保存位置官方文档中是在/tmp目录，
注：经实测此步不用创建也可以，因为后面我们用rman恢复备库的时候也直接会把控制文件给恢复过去的。

6.7，RMAN备份数据库
6.7.1，使用rman对database和archive log进行备份
注意：备份的时候一定要注意空间的大小，rman备份的数据非常的大，

6.7.3，打包压缩
由于rman备份的数据太大，我们用tar进行打包压缩
[oracle@adg rman_backup]$ tar -czvf rmanbak20191029.tgz ./ARC_*.bak ./FULL_*.bak ./ARC_03uffu43_1_1.bak ./ARC_0auffu77_1_1.bak ./ARC_0buffu77_1_1.bak ./ARC_0cuffu77_1_1.bak ./ARC_0duffu77_1_1.bak ./ARC_0euffu77_1_1.bak ./FULL_01uffu2i_1_1.bak ./FULL_02uffu3v_1_1.bak ./FULL_04uffu5u_1_1.bak ./FULL_05uffu5u_1_1.bak ./FULL_06uffu5u_1_1.bak ./FULL_07uffu5u_1_1.bak ./FULL_08uffu70_1_1.bak ./FULL_09uffu75_1_1.bak
6.8，拷贝所有备份文件到备库
拷贝控制文件，密码文件，参数文件，监听文件，rman备份文件等到备库上，
注意：主库rman的备份复制到备库时，复制到的目录一定要和主库rman备份的目录相同。
#在备库建立相应的目录 [oracle@dg ~]$ mkdir -p /data/app/rman_backup #在主库把备份文件拷到备库上 [oracle@adg rman_backup]$ scp -p 12525 -l 100000 initphydb1.ora orapworcl standby.ctl rmanbak20191029.tgz oracle@dg:/data/app/rman_backup/ Warning: Permanently added 'dg,192.168.25.45' (ECDSA) to the list of known hosts. oracle@dg's password: 100000: No such file or directory initphydb1.ora 100% 1626 186.5KB/s 00:00 orapworcl 100% 1536 134.3KB/s 00:00 standby.ctl 100% 9520KB 16.1MB/s 00:00 rmanbak20191029.tgz 100% 543MB 14.7MB/s 00:37 #备库看一下 [oracle@dg rman_backup]$ pwd /data/app/rman_backup [oracle@dg rman_backup]$ ll total 565224 -rw-r--r-- 1 oracle oinstall 1626 Oct 28 05:11 initphydb1.ora -rw-r----- 1 oracle oinstall 1536 Oct 28 04:26 orapworcl -rw-r--r-- 1 oracle oinstall 569031597 Oct 28 22:41 rmanbak20191029.tgz -rw-r----- 1 oracle oinstall 9748480 Oct 28 21:49 standby.ctl
7，对备库进行配置
7.1，建立相应的文件目录
（因为备库没有创建实例，所以是没有相关的目录的，我们需要参考主库的位置来创建。包括dump文件目录，闪回区，数据文件目录，通过show parameter dest 命令查看且pfile参数文件里涉及到的目录都要在备库创建）
#备库创建相应的目录： [oracle@dg ~]$ mkdir -p $ORACLE_BASE/admin/orcl/adump [oracle@dg ~]$ mkdir -p $ORACLE_BASE/admin/orcl/dpdump [oracle@dg ~]$ mkdir -p $ORACLE_BASE/admin/orcl/cdump [oracle@dg ~]$ mkdir -p $ORACLE_BASE/diag/rdbms/orcl_pri/orcl/trace [oracle@dg ~]$ mkdir -p $ORACLE_BASE/admin/orcl_sty/adump [oracle@dg ~]$ mkdir -p $ORACLE_BASE/admin/orcl_sty/dpdump [oracle@dg ~]$ mkdir -p $ORACLE_BASE/admin/orcl_sty/cdump [oracle@dg ~]$ mkdir -p $ORACLE_BASE/diag/rdbms/orcl_sty/orcl_sty/trace [oracle@dg ~]$ mkdir -p $ORACLE_BASE/diag/rdbms/orcl_sty/orcl/trace
---在主库通过SQL> show parameter db_recovery_file_dest;查看，然后在备库中创建相同的目录 SQL> show parameter db_recovery_file_dest; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_recovery_file_dest string /data/app/oracle/fast_recovery _area db_recovery_file_dest_size big integer 50G SQL> show parameter db_file_name_convert NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ db_file_name_convert string /data/app/oracle/oradata/orcl/ , /data/app/oracle/oradata/orc l/ SQL> show parameter log_file_name_convert; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ log_file_name_convert string /data/app/oracle/oradata/orcl/ , /data/app/oracle/oradata/orc l/
#备库： [oracle@dg ~]$ mkdir -p $ORACLE_BASE/fast_recovery_area/ [oracle@dg ~]$ mkdir -p $ORACLE_BASE/oradata/orcl
文件目录说明：
adump --> audit_file_dest dpdump --> 是存放一些登录信息的 trace --> background_dump_dest 警告日志：也就是alert log，在系统初始化参数文件设置的show parameter background_dump_dest对应的就是它的位置。 cdump --> 记录核心dump的目录，如果oracle核心进程应为BUG等原因崩溃，会做内存的dump，dump文件保存在该目录下。 fast_recovery_area --> 闪回区 oradata/orcl --> log_archive_dest_1和db_file_name_convert，即日志和数据文件目录，由pfile文件中定义的。
7.2，生成密码文件信息
正常的应该是和主库的密码文件内容保持相同，名称也要保持相同一样。
[oracle@dg ~]$ cp /data/app/rman_backup/orapworcl $ORACLE_HOME/dbs/ [oracle@dg ~]$ ll $ORACLE_HOME/dbs/ total 8 -rw-r--r-- 1 oracle oinstall 2851 May 15 2009 init.ora -rw-r----- 1 oracle oinstall 1536 Oct 29 01:16 orapworcl
7.3，存放控制文件
---首先看一下主库的地址 主： SQL> show parameter control_file; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ control_file_record_keep_time integer 7 control_files string /data/app/oracle/oradata/orcl/ control01.ctl, /data/app/oracl e/fast_recovery_area/orcl/cont rol02.ctl
---指定实际dg的控制文件路径，此路径可自定义，与pfile文件保持一致， 备：
[oracle@dg ~]$ mkdir -p /data/app/oracle/fast_recovery_area/orcl/ [oracle@dg ~]$ cp /data/app/rman_backup/standby.ctl /data/app/oracle/oradata/orcl/control01.ctl [oracle@dg ~]$ cp /data/app/rman_backup/standby.ctl /data/app/oracle/fast_recovery_area/orcl/control02.ctl [oracle@dg ~]$ ll /data/app/oracle/oradata/orcl/control01.ctl -rw-r----- 1 oracle oinstall 9748480 Oct 29 01:22 /data/app/oracle/oradata/orcl/control01.ctl [oracle@dg ~]$ ll /data/app/oracle/fast_recovery_area/orcl/control02.ctl -rw-r----- 1 oracle oinstall 9748480 Oct 29 01:22 /data/app/oracle/fast_recovery_area/orcl/control02.ctl
7.4，修改pfile参数文件
首先再查看一下主库上的数据文件，临时文件，日志文件存放路径
主库：
---查看数据文件路径 SQL> set line 2000 pages 200; SQL> col file_name for a50; SQL> select tablespace_name,file_name from dba_data_files; TABLESPACE_NAME FILE_NAME ------------------------------ -------------------------------------------------- USERS /data/app/oracle/oradata/orcl/users01.dbf UNDOTBS1 /data/app/oracle/oradata/orcl/undotbs01.dbf SYSAUX /data/app/oracle/oradata/orcl/sysaux01.dbf SYSTEM /data/app/oracle/oradata/orcl/system01.dbf ---查看临时文件存放路径 SQL> col name for a50 SQL> select name from v$tempfile; NAME -------------------------------------------------- /data/app/oracle/oradata/orcl/temp01.dbf ---查看主库日志文件的路径 SQL> select group#,member from v$logfile; GROUP# MEMBER ---------- --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 3 /data/app/oracle/oradata/orcl/redo03.log 2 /data/app/oracle/oradata/orcl/redo02.log 1 /data/app/oracle/oradata/orcl/redo01.log 4 /data/app/oracle/oradata/orcl/redo04.log 5 /data/app/oracle/oradata/orcl/redo05.log 6 /data/app/oracle/oradata/orcl/redo06.log 7 /data/app/oracle/oradata/orcl/redo07.log 7 rows selected.
备库：

7.5，启动备库到nomount状态
使用修改后的初始化文件启动备库到nomount状态
备库：
[oracle@dg dbs]$ sqlplus / as sysdba SQL> startup pfile='/data/app/oracle/product/11.2.0.4/db_1/dbs/initorcl_sty.ora' nomount; ORACLE instance started. Total System Global Area 7349010432 bytes Fixed Size 2267464 bytes Variable Size 1728054968 bytes Database Buffers 5603590144 bytes Redo Buffers 15097856 bytes SQL> create spfile from pfile='/data/app/oracle/product/11.2.0.4/db_1/dbs/initorcl_sty.ora'; File created.
7.6，备库恢复控制文件
备：
[oracle@dg ~]$ rman target / RMAN> restore controlfile from '/data/app/oracle/oradata/orcl/control01.ctl'; Starting restore at 2019-10-29 02:00:56 using target database control file instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=572 device type=DISK channel ORA_DISK_1: copied control file copy output file name=/data/app/oracle/oradata/orcl/control01.ctl output file name=/data/app/oracle/fast_recovery_area/orcl/control02.ctl Finished restore at 2019-10-29 02:00:57 RMAN> exit Recovery Manager complete.
7.7，切换备库到mount状态
备：
[oracle@dg ~]$ sqlplus / as sysdba SQL> alter database mount; Database altered. SQL> select status from v$instance; STATUS ------------ MOUNTED
7.8，rman将主库数据恢复到备库
解压rman备份的文件
备：

7.9，启动备库
重启启动备库
[oracle@dg ~]$ sqlplus / as sysdba SQL> select status from v$instance; STATUS ------------ MOUNTED SQL> shutdown immediate; ORA-01109: database not open Database dismounted.

8.验证主备库同步
8.1，dg状态下进行验证
验证过程中如果出现问题看主库和备库的
$ORACLE_BASE/diag/rdbms/orcl_pri/orcl/trace/和
$ORACLE_BASE/diag/rdbms/phydb3/orcl/trace目录中的trace文件。8.1.1，备库查看RFS接收日志进程和MRP应用日志进程，以及同步主库情况
备库：
SQL> set lin 3000 pages 3000; SQL> select process,sequence#,status,delay_mins from v$managed_standby; PROCESS SEQUENCE# STATUS DELAY_MINS --------- ---------- ------------ ---------- ARCH 0 CONNECTED 0 ARCH 0 CONNECTED 0 ARCH 14 CLOSING 0 ARCH 0 CONNECTED 0 RFS 0 IDLE 0 RFS 15 IDLE 0 RFS 0 IDLE 0 MRP0 15 APPLYING_LOG 0 8 rows selected.
如上所示，有RFS接收日志进程，有MRP0 进程且MRP0 进程状态正常，则表示DG运行正常。
其中：ARCH是归档进程，RFS是归档传输进程，MRP0是日志应用进程
注意：如果没有RFS进程看一下trace里的错误信息有助于帮助，如果都是按照上面做的话应该没有问题你可以尝试关闭selinux和防火墙，还有密码要和主一样
8.1.2，查看archive log list序列是否一致
在主库上，如果最后一行数字相同说明配置成功。
主：
[oracle@adg ~]$ sqlplus / as sysdba SQL> select status from v$instance; STATUS ------------ OPEN SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 13 Next log sequence to archive 15 Current log sequence 15
在备库上如果最后一行数字相同说明配置成功
备：
[oracle@dg ~]$ sqlplus / as sysdba SQL> select status from v$instance; STATUS ------------ MOUNTED SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /data/app/oracle/fast_recovery_area Oldest online log sequence 0 Next log sequence to archive 0 Current log sequence 15
8.1.3，切日志
在主库上执行alter system switch logfile;再去查看archive log list 查看主备库的current log sequence 是否一致。如果一致，这是正确的配置。
主：
SQL> alter system switch logfile; System altered. SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 14 Next log sequence to archive 16 Current log sequence 16
备：
SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /data/app/oracle/fast_recovery_area Oldest online log sequence 15 Next log sequence to archive 0 Current log sequence 16
8.1.4，查看有没有gap
主：
SQL> select status,gap_status from v$archive_dest_status where dest_id=2; STATUS GAP_STATUS --------- ------------------------ VALID NO GAP SQL> select * from v$archive_dest_status where dest_id=2;
备：
SQL> select status,gap_status from v$archive_dest_status where dest_id=2; STATUS GAP_STATUS --------- ------------------------ VALID
说明DG正常

8.1.6，查询数据库模式是否正常
主：
SQL> set lin 3000 pages 300; SQL> select dbid,name,open_mode,current_scn,protection_mode,database_role,force_logging,open_mode,switchover_status from v$database; DBID NAME OPEN_MODE CURRENT_SCN PROTECTION_MODE DATABASE_ROLE FOR OPEN_MODE SWITCHOVER_STATUS ---------- --------- -------------------- ----------- -------------------- ---------------- --- -------------------- -------------------- 1550594382 ORCL READ WRITE 1058731 MAXIMUM PERFORMANCE PRIMARY YES READ WRITE TO STANDBY
备：

8.2，开启备库ADG状态进行验证
8.2.1，开启备库的ADG
备：
--取消日志应用 SQL> alter database recover managed standby database cancel; Database altered. --以open模式打开数据库 SQL> alter database open; Database altered. SQL> select status from v$instance; STATUS ------------ OPEN --开启日志应用 SQL> alter database recover managed standby database using current logfile disconnect from session; Database altered. --查询数据库模式是否正常 SQL> set lin 3000 pages 300; SQL> select dbid,name,open_mode,current_scn,protection_mode,database_role,force_logging,open_mode,switchover_status from v$database; DBID NAME OPEN_MODE CURRENT_SCN PROTECTION_MODE DATABASE_ROLE FOR OPEN_MODE SWITCHOVER_STATUS ---------- --------- -------------------- ----------- -------------------- ---------------- --- -------------------- -------------------- 1550594382 ORCL READ ONLY WITH APPLY 1059251 MAXIMUM PERFORMANCE PHYSICAL STANDBY YES READ ONLY WITH APPLY NOT ALLOWED
8.2.2，再次验证主备状态
再次检查DG2状态是否正常
查看archive log list 序列是否一致
---在主库上， 如果最后一行数字相同， 如果相同说明配置成功 主：
SQL> select status from v$instance; STATUS ------------ OPEN SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 14 Next log sequence to archive 16 Current log sequence 16
备：
---在备库上，如果最后一行数字相同， 如果相同说明配置成功 SQL> select status from v$instance; STATUS ------------ OPEN SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /data/app/oracle/fast_recovery_area Oldest online log sequence 15 Next log sequence to archive 0 Current log sequence 16
切日志
---在主库上执行alter system switch logfile;再去查看archive log list 查看主备库的current log sequence 是否一致。如果一致，这是正确的配置 主：
SQL> alter system switch logfile; System altered. SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 15 Next log sequence to archive 17 Current log sequence 17
备：
SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /data/app/oracle/fast_recovery_area Oldest online log sequence 15 Next log sequence to archive 0 Current log sequence 17
查看有没有gap
主；
SQL> select status,gap_status from v$archive_dest_status where dest_id=2; STATUS GAP_STATUS --------- ------------------------ VALID NO GAP SQL> select * from v$archive_dest_status where dest_id=2; DEST_ID DEST_NAME STATUS TYPE DATABASE_MODE RECOVERY_MODE PROTECTION_MODE DESTINATION STANDBY_LOGFILE_COUNT STANDBY_LOGFILE_ACTIVE ARCHIVED_THREAD# ARCHIVED_SEQ# APPLIED_THREAD# APPLIED_SEQ# ERROR SRL DB_UNIQUE_NAME SYNCHRONIZATION_STATUS SYN GAP_STATUS ---------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- --------- -------------- --------------- ----------------------- -------------------- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- --------------------- ---------------------- ---------------- ------------- --------------- ------------ ----------------------------------------------------------------- --- ------------------------------ ---------------------- --- ------------------------ 2 LOG_ARCHIVE_DEST_2 VALID PHYSICAL OPEN_READ-ONLY MANAGED REAL TIME APPLY MAXIMUM PERFORMANCE orcl_sty 5 1 1 16 1 15 YES orcl_sty CHECK CONFIGURATION NO NO GAP
备:
SQL> select status,gap_status from v$archive_dest_status where dest_id=2; STATUS GAP_STATUS --------- ------------------------ VALID NO GAP
说明DG1正常
备库查看RFS接收日志和MRP应用日志同步主库情况
备：
SQL> set lin 3000 pages 300; SQL> select process, sequence#,status,delay_mins from v$managed_standby; PROCESS SEQUENCE# STATUS DELAY_MINS --------- ---------- ------------ ---------- ARCH 0 CONNECTED 0 ARCH 0 CONNECTED 0 ARCH 16 CLOSING 0 ARCH 0 CONNECTED 0 RFS 0 IDLE 0 RFS 17 IDLE 0 RFS 0 IDLE 0 MRP0 17 APPLYING_LOG 0 8 rows selected.
如上面所示，有RFS接收日志进程，有MRP0 进程且MRP0 进程状态正常，则表示DG运行正常。 其中：ARCH是归档进程，RFS是归档传输进程，MRP0是日志应用进程
查看日志应用进度，数据库模式是否正常
主：
SQL> set lin 3000 pages 300; SQL> select dbid,name,open_mode,current_scn,protection_mode,database_role,force_logging,open_mode,switchover_status from v$database; DBID NAME OPEN_MODE CURRENT_SCN PROTECTION_MODE DATABASE_ROLE FOR OPEN_MODE SWITCHOVER_STATUS ---------- --------- -------------------- ----------- -------------------- ---------------- --- -------------------- -------------------- 1550594382 ORCL READ WRITE 1060210 MAXIMUM PERFORMANCE PRIMARY YES READ WRITE TO STANDBY

8.3，数据测试
主：
SQL> alter system switch logfile; System altered. SQL> create table test as select * from dba_objects; Table created. SQL> insert into test select * from test; 86259 rows created. SQL> insert into test select * from test; 172518 rows created. SQL> commit; Commit complete. SQL> insert into test select * from test; 345036 rows created. SQL> commit; Commit complete. SQL> insert into test select * from test; 690072 rows created. SQL> commit; Commit complete. SQL> select count(*) from test; COUNT(*) ---------- 1380144
备：
SQL> select count(*) from test; COUNT(*) ---------- 1380144
主库再次执行 主：
SQL> drop table test; Table dropped. SQL> select cout(*) from test; select cout(*) from test * ERROR at line 1: ORA-00936: missing expression
备：
SQL> select count(*) from test; COUNT(*) ---------- 1380144 SQL> select count(*) from test; select count(*) from test * ERROR at line 1: ORA-00942: table or view does not exist
