Oracle 12c Data Guard 纯小白部署手册

子公司需要搭建数据仓库，并且新建ADG作为主从，硬件设备Dell R730机器；
192.168.1.11 dwjrdb --主库
192.168.1.12 dwjrstdyd --备库
--数据库软件：linuxx64_12201_database.zip
--数据库补丁包：p27105253_122010_Linux-x86-64.zip
--Opatch升级包：p6880880_122010_Linux-x86-64.zip
--目录规划为/u01存放归档日志，数据文件等，目录6.6TB空间

一、数据库安装实施步骤如下：
1、关闭防火墙：
systemctl stop firewalld
systemctl disable firewalld

systemctl stop firewalld.service
systemctl disable firewalld.service
chkconfig NetworkManager off

2、配置主机名和IP地址对应关系
vi /etc/hosts 添加如下内容

192.168.1.11 dwjrdb
192.168.1.12 dwjrstdydb

修改主备库两端主机名
/etc/hostname
dwjrdb

/etc/hostname
dwjrstdydb

3、安装依赖包：(oracle linux 7.2依赖包如下，具体可参考官方文档)

yum clean all
yum install -y binutils-
yum install -y compat-libcap1-
yum install -y compat-libstdc
yum install -y glibc-
yum install -y glibc-devel-
yum install -y ksh
yum install -y libaio-
yum install -y libaio-devel
yum install -y libX11-
yum install -y libXau-
yum install -y libXi-
yum install -y libXtst-
yum install -y libgcc-
yum install -y libstdc
yum install -y libstdc++-devel
yum install -y libxcb-
yum install -y make
yum install -y nfs-utils-
yum install -y net-tools-
yum install -y smartmontools-
yum install -y sysstat-
yum install -y compat-libcap1
yum install -y sysstat-
yum install -y libaio-devel-
yum install -y compat-libcap1-*

4、关闭transparent hugepages，设置hugepages
查看transparent hugepage
Red Hat Enterprise Linux kernels:

cat /sys/kernel/mm/redhat_transparent_hugepage/enabled

Other kernels:

cat /sys/kernel/mm/transparent_hugepage/enabled

oracle linux 7.2 没有开启transparent hugepages，忽略。

5、添加NTP时间同步，root下执行
[[email protected] ~]# crontab -l
/5 * /usr/sbin/ntpdate 1.1.1.1 >/dev/null 2>&1

6、用户和组：
groupadd -g 501 oinstall
groupadd -g 502 dba
groupadd -g 503 oper
groupadd -g 504 backupdba
groupadd -g 505 dgdba
groupadd -g 506 kmdba
groupadd -g 507 racdba

/usr/sbin/useradd -u 500 -g oinstall -G oinstall,dba,oper,backupdba,dgdba,kmdba,racdba oracle

7、目录：
mkdir -p /u01/app/oraInventory
chown -R oracle:oinstall /u01/app/oraInventory
chmod -R 775 /u01/app/oraInventory

mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle

mkdir -p /u01/app/oracle/product/12.2.0/db_1
chown -R oracle:oinstall /u01/app/oracle/product/12.2.0/db_1
chmod -R 775 /u01/app/oracle/product/12.2.0/db_1

mkdir -p /u01/arch
chown -R oracle:oinstall /u01/arch
chmod -R 775 /u01/arch

备库
mkdir -p /u01/app/oracle/oradata/dwjrstdydb
chown -R oracle:oinstall /u01/app/oracle/oradata/dwjrstdydb
chmod -R 775 /u01/app/oracle/oradata/dwjrstdydb

8、环境变量

主库：
export ORACLE_SID=dwjrdb
export ORACLE_BASE=/u01/app/oracle/
export ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
umask 022
stty erase ^h

备库：
export PATH
export ORACLE_SID=dwjrstdydb
export ORACLE_BASE=/u01/app/oracle/
export ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
umask 022
stty erase ^h

9、内核参数：

vi /etc/sysctl.conf
kernel.shmmax = 236223201280
kernel.shmall = 57671680
kernel.shmmni = 4096
kernel.sem = 5010 641280 5010 128
fs.file-max = 6815744
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default=1048576
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048576
fs.aio-max-nr=1048576
vm.swappiness = 0
vm.nr_hugepages = 62850

--保存生效
/sbin/sysctl -p

10、限制文件：/etc/security/limits.conf

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240

11、vi /etc/pam.d/login文件
session required pam_limits.so

vi /etc/profile

if [ $USER = "oracle" ] || [ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi

12、启动图形化窗口执行databas建库脚本
a》error启动不起来设定export DISPLAY=:11未果；

b》直接用xmanager登陆oracle用户，执行安装脚本可以；

13、创建完成后，dbca建库、netca创建监听

14、备库端只装sqlplus软件不建库

15、修改数据库参数
alter system set open_cursors=500 container=all;
alter system set processes=5000 scope=spfile;
alter system set db_files=5000 scope=spfile;
alter system set undo_retention=7200 scope=spfile;
alter system set "_undo_autotune"=FALSE scope=spfile;
alter system set DEFERRED_SEGMENT_CREATION=false scope=spfile;

16、更新OPatch版本，OPatch直接压缩替换，并且将patch打上。
1.(1) 上传p6880880_122010_Linux-x86-64.zip到/u01/software目录下, /u01/software给777权限。
(2) root用户下将原OPatch目录改名。

mv /u01/app/oracle/product/12.2.0/db_1/OPatch /u01/app/oracle/product/12.2.0/db_1/OPatchBAK

  1. oracle目录OPatch替换
    (1) root用户

cd /u01/software/;chown oracle:oinstall p6880880_122010_Linux-x86-64.zip

(2) oracle用户

su - oracle cd /u01/software/ ; unzip p6880880_122010_Linux-x86-64.zip

(3) root用户

cd /u01/software/; mv OPatch /u01/app/oracle/product/12.1.0/db_1/

(4) oracle用户测试

su - oracle /u01/app/oracle/product/12.1.0/db_1/OPatch/opatch version

打补丁
[[email protected] 27105253]$ cd /software/27105253
[[email protected] 27105253]$ /u01/app/oracle/product/12.2.0/db_1/OPatch/opatch apply

17、设定pdb随cdb启动参数
alter pluggable database all save state;

18、添加数据文件参考现历史库

--CDB--
ALTER DATABASE DATAFILE ‘/u01/app/oracle/oradata/dwjrdb/system01.dbf‘ RESIZE 1024M;
ALTER DATABASE DATAFILE ‘/u01/app/oracle/oradata/dwjrdb/undotbs01.dbf‘ RESIZE 5120M;

ALTER TABLESPACE TEMP ADD TEMPFILE ‘/u01/app/oracle/oradata/dwjrdb/dwjrdbpdb/temp04.dbf‘ SIZE 30720M;

--添加redo日志，初始化redo太小，并将redo组1-3全部剔除
alter database add logfile group 4 (‘/u01/app/oracle/oradata/dwjrdb/redo04a.log‘)size 1024M;

alter database add logfile member ‘/u01/app/oracle/oradata/dwjrdb/redo05b.log‘ to group 5;
--剔除redo组1-3，查看redo状态为INACTIVE即可drop
select GROUP#,STATUS,MEMBERS from v$log;
alter database drop logfile group 1;
alter database drop logfile group 2;
alter database drop logfile group 3; 一直是current，将组1,2回切
[[email protected] ~]$ cd /u01/app/oracle/oradata/dwjrdb/
[[email protected] dwjrdb]$ rm -rf redo01.log redo02.log
alter database add logfile group 1 (‘/u01/app/oracle/oradata/dwjrdb/redo01a.log‘)size 1024M;

alter database drop logfile group 3; --切日志后日志不活动
[[email protected] ~]$ cd /u01/app/oracle/oradata/dwjrdb/
[[email protected] dwjrdb]$ rm -rf redo03.log
alter database add logfile group 3 (‘/u01/app/oracle/oradata/dwjrdb/redo03a.log‘)size 1024M;
alter database add logfile member ‘/u01/app/oracle/oradata/dwjrdb/redo03b.log‘ to group 3;

--增加控制文件--
SQL> select name from v$controlfile;
/u01/app/oracle/oradata/dwjrdb/control01.ctl
/u01/app/oracle/oradata/dwjrdb/control02.ctl
--加控制文件
alter system set control_files=‘/u01/app/oracle/oradata/dwjrdb/control01.ctl‘,‘/u01/app/oracle/oradata/dwjrdb/control02.ctl‘,‘/u01/app/oracle/oradata/dwjrdb/control03.ctl‘ scope=spfile;

shutdown immediate;
cp control01.ctl control03.ctl
startup
SQL> select name from v$controlfile;
NAME

/u01/app/oracle/oradata/dwjrdb/control01.ctl
/u01/app/oracle/oradata/dwjrdb/control02.ctl
/u01/app/oracle/oradata/dwjrdb/control03.ctl

二、ADG的搭建步骤

192.168.1.11 dwjrdb --主库

192.168.1.12 dwjrstdydb --备库—安装数据库软件，等配置dg后将数据库升级opatch并打补丁

1、修改主备监听文件
主库： listener.ora

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dwjrdb)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME =dwjrdb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrdb)
)
(SID_DESC =
(GLOBAL_DBNAME =dwjrstdydb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrstdydb)
)
)

如果配置broker的话，需要新增listener.ora中
(SID_DESC =
(GLOBAL_DBNAME =dwjrdb_DGMGRL)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrdb)
)

--tnsnames.ora

dwjrdb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dwjrdb)
)
)

dwjrstdydb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.12)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dwjrstdydb)
)
)

--备库

--listener.ora

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME =dwjrdb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrdb)
)
(SID_DESC =
(GLOBAL_DBNAME =dwjrstdydb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrstdydb)
)
)

--tnsnames.ora

dwjrdb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dwjrdb)
)
)

dwjrstdydb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 1192.168.1.12)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dwjrstdydb)
)
)

--重新启动主备库监听
lsnrctl reload

--测试

tnsping dwjrdb
tnsping dwjrstdydb
sqlplus sys/[email protected] as sysdba
sqlplus sys/[email protected] as sysdba

2、修改主库必要参数（CDB中执行即可）

select force_logging from v$database; --查询是否开启

alter database force logging;--开启强制记录日志

alter database archivelog;--开启归档

alter system set standby_file_management=auto;--手动

alter system set log_archive_dest_1=‘location=/u01/arch valid_for=(all_logfiles,all_roles) db_unique_name=dwjrdb‘ scope=spfile;--开启本地归档

alter system set log_archive_dest_2=‘SERVICE=dwjrstdydb LGWR ASYNC valid_for=(all_logfiles,all_roles) db_unique_name=dwjrstdydb‘ scope=spfile;--开启远程归档

alter system set log_archive_config=‘dg_config=(dwjrdb,dwjrstdydb)‘;--开启DG功能

alter system set fal_client=‘dwjrdb‘;--指定源端

alter system set fal_server=‘dwjrstdydb‘;--指定目标端

alter system set log_archive_dest_state_2=enable;--启动应用

alter system set log_archive_dest_state_1=enable;--启动应用

alter system set log_archiveformat=‘dwjrdb%t%s_%r.dbf‘ scope=spfile;--指定归档文件形式

--源端--先写备端地址，在写源端地址

alter system set db_file_name_convert=‘/u01/app/oracle/oradata/dwjrstdydb/‘,‘/u01/app/oracle/oradata/dwjrdb/‘ scope=spfile;
alter system set log_file_name_convert=‘/u01/app/oracle/oradata/dwjrstdydb/‘,‘/u01/app/oracle/oradata/dwjrdb/‘ scope=spfile;

select bytes/1024/1024 from v$log;--查询日志大小

select member from v$logfile;--查询日志位置

select GROUP#,BYTES/1024/1024/1024 G from v$log;--查询组的个数，以及大小

select group#,thread#,members,archived,status from v$log;--查询当前使用的是那个日志组

--添加 standby logfile

alter database add standby logfile group 6 (‘/u01/app/oracle/oradata/dwjrdb/standby06a.log‘,
‘/u01/app/oracle/oradata/dwjrdb/standby06b.log‘) size 1G ;
alter database add standby logfile group 7 (‘/u01/app/oracle/oradata/dwjrdb/standby07a.log‘,
‘/u01/app/oracle/oradata/dwjrdb/standby07b.log‘) size 1G ;
alter database add standby logfile group 8 (‘/u01/app/oracle/oradata/dwjrdb/standby08a.log‘,
‘/u01/app/oracle/oradata/dwjrdb/standby08b.log‘) size 1G ;
alter database add standby logfile group 9 (‘/u01/app/oracle/oradata/dwjrdb/standby09a.log‘,
‘/u01/app/oracle/oradata/dwjrdb/standby09b.log‘) size 1G ;
alter database add standby logfile group 10 (‘/u01/app/oracle/oradata/dwjrdb/standby10a.log‘,
‘/u01/app/oracle/oradata/dwjrdb/standby10b.log‘) size 1G ;
alter database add standby logfile group 11 (‘/u01/app/oracle/oradata/dwjrdb/standby11a.log‘,
‘/u01/app/oracle/oradata/dwjrdb/standby11b.log‘) size 1G ;

---重启主库数据库，使修改参数生效

shut immediate;

startup

---生成 pfile 文件

create pfile from spfile;

---传递密码文件

cd $ORACLE_HOME/dbs

scp orapwdwjrdb 192.168.1.12:/u01/app/oracle/product/12.2.0/db_1/dbs/orapwdwjrstdydb

---传递参数文件
cd $ORACLE_HOME/dbs
scp initdwjrdb.ora 192.168.1.12:/u01/app/oracle/product/12.2.0/db_1/dbs/initdwjrstdydb.ora

3、修改备库参数文件initteststdydb.ora相关参数

--创建audit_file_dest 目录（改成备库的）

mkdir -p /u01/app/oracle/admin/dwjrstdydb/adump

--创建control_files 路径

mkdir -p /u01/app/oracle/oradata/dwjrstdydb

--修改db_file_name_convert、log_file_name_convert 路径

.db_file_name_convert=‘/u01/app/oracle/oradata/dwjrdb‘,‘/u01/app/oracle/oradata/dwjrstdydb‘
.log_file_name_convert=‘/u01/app/oracle/oradata/dwjrdb‘,‘/u01/app/oracle/oradata/dwjrstdydb‘

--添加db_unique_name参数

*.db_unique_name=‘dwjrstdydb‘

---修改下列参数

.fal_client=‘dwjrstdydb‘
.fal_server=‘dwjrdb‘

*.log_archive_dest_1=‘location=/u01/arch valid_for=(all_logfiles,all_roles) db_unique_name=dwjrstdydb‘

*.log_archive_dest_2=‘‘

*.log_archiveformat=‘dwjrstdydb%t%s%r.arc‘

--修改备库控制文件的路径，因为是复制过来的，控制文件目录还是原端的

--启动备库到nomount

startup nomount;

4、主库执行恢复操作

rman target sys/[email protected] auxiliary sys/[email protected]

duplicate target database for standby nofilenamecheck from active database;
--返回结果
datafile 10 switched to datafile copy
input datafile copy RECID=10 STAMP=980117877 file name=/u01/app/oracle/oradata/dwjrstdydb/dwjrdbpdb/undotbs01.dbf
datafile 11 switched to datafile copy
input datafile copy RECID=11 STAMP=980117877 file name=/u01/app/oracle/oradata/dwjrstdydb/dwjrdbpdb/users01.dbf
datafile 12 switched to datafile copy
input datafile copy RECID=12 STAMP=980117877 file name=/u01/app/oracle/oradata/dwjrstdydb/dwjrdbpdb/undotbs02.dbf

Finished Duplicate Db at 29-JUN-18

---上面操作完成，备库就处于mount状态

alter database open;---起主库

---备库应用日志

alter database recover managed standby database using current logfile disconnect from session;

alter database recover managed standby database cancel;---取消应用

--查询备库日志是否应用

select sequence#,applied from v$archived_log;

---查询备库进程是否正常

select process,client_process,sequence#,status from v$managed_standby;

SQL> select process, status, thread#,sequence#, block#, blocks from v$managed_standby;

PROCESS STATUS THREAD# SEQUENCE# BLOCK# BLOCKS


MRP0 APPLYING_LOG 1 110 86 2097152

---查询主备库状态

select DATABASE_ROLE,SWITCHOVER_STATUS from v$database;

5、验证

--创建一个测试表a；进行增删改操作；在备库验证是否同步
create table a(a int);

三、配置dg borker
1、修改主备库监听文件，tns文件。

主库listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME =dwjrdb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrdb)
)
(SID_DESC =
(GLOBAL_DBNAME =dwjrstdydb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrstdydb)
)
(SID_DESC =
(GLOBAL_DBNAME =dwjrdb_DGMGRL)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrdb)
)
)

备库listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME =dwjrdb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrdb)
)
(SID_DESC =
(GLOBAL_DBNAME =dwjrstdydb)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrstdydb)
)
(SID_DESC =
(GLOBAL_DBNAME =dwjrstdydb_DGMGRL)
(ORACLE_HOME=/u01/app/oracle/product/12.2.0/db_1)
(SID_NAME = dwjrstdydb)
)
)

主库tnsname文件中pdb是初建时候ip为11.11
[[email protected] ~]$ more /u01/app/oracle/product/12.2.0/db_1/network/admin/tnsnames.ora
DWJRDBPDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.11)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DWJRDBPDB)
)
)
备库tnsnames。ora文件中是初建时候，所以ip为11.11，改为11.12
[[email protected] admin]$ vi tnsnames.ora
DWJRDBPDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.12)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = DWJRDBPDB)
)
)

2、两边实例均 设置dg_broker_start=true;
primary :
alter system set dg_broker_start=true;

standby :

Oracle 12c Data Guard 搭建手册

Oracle 12c 的DataGuard 是在CDB 级别进行的,所以我们的配置都是从CDB角度出发. 测试里主备库的数据库CDB名称相同. 1  环境说明 OS Version: [[email protected] etc]# cat /etc/oracle-release Oracle Linux Server release 6.3 [[email protected] etc]# uname -r 2.6.39-200.29.3.el6uek.x86_64 DB Version: S

Oracle RAC + Data Guard 环境搭建

国庆之前就准备做这个实验了. 后来时间不够,就没搞了. 6天的长假一放,都散漫的不成样子了.懒散了很多. 今天7号. 上班也没啥精神,但是该做的实验还得继续. Oracle 高可用性的三个主要体现是: RAC, Data Guard 和 Stream.  所以熟练掌握这些技术就是评价DBA的标准一个. RAC + Data Guard 主要用在灾备或者报表服务器上. 比如用RAC+ 逻辑standby 做报表,从而减轻RAC 系统的压力. 关于Data Guard 的一些原理知识可以参考: Or

Oracle 11g Data Guard 之逻辑备库角色转换

逻辑备库不复制数据库服务,在进行switchover或者failover时,连接主库服务的中间层将不能连接(因为服务的创建没有被复制),或者连接不正确的版本(因为服务属性的修改没有被复制). Oracle集群不复制管理逻辑备库的服务,必须手动对主库与备库进行同步,具体的详参Oracle集群管理和部署的相关内容. 一.逻辑备库的switchover操作 当进行switchover操作来改变主库和逻辑备库的角色时,总是在主库启动switchover,然后在逻辑备库完成操作,其中的步骤必须按顺序,否则

ORACLE 11G Data Guard 角色转换

1,ORACLE Dataguard角色切换DataGuard已经是现今标准的主流容灾方案,由于日志传递对于网络适应程度强,且可以采用同步实时的传递方式和异步延迟的传递方式,甚至可以成为远程的异地容灾方案.不管用于何种用途,DG都免不了要进行角色转换,即将standby 数据库切换为primary数据库,角色转换分为:switchover和failover两种 2,两种方式的异同1),switchover是primary库转换成standby库.standby库转换成primary库2),fai

Oracle 11g Data Guard 物理备库快速配置指南（上）

缘起 最近做了10g和11g的物理备库配置实验,发现 Data Guard 其实很容易,但是缺少好文档.我是参考官方文档做的实验,觉得它写的不是很清楚的. Google 出来两个pdf文档,读了觉得比官方文档强很多.翻译下,也许会对某些朋友有用.翻译的同时我也好更熟悉下这两个文档.好久没翻译过英文了,可以顺便练练手. 原文档下载地址(墙外): Configure Dataguard 11gR2 Physical Standby Part 1 Configure Dataguard 11gR2 P

Oracle 11g Data Guard 使用duplicate from active database 创建 standby database

用这种方式来搭建DG ,主库的停机时间很少,只需要重启一下,使参数生效.也可以用这种方法进行DB迁移.DG搭建好,然后把备库激活就可以了. 这样整个迁移中宕机时间也比较短. Oracle 11g的pyhsical standby 支持open read only 下的apply和Real-time query. 因此就有了physical standby 稳定和logical standby 的报表查询功能. Oracle: 11.2.0.1 OS: redhat 5.5 Primary IP:

Oracle 11g Data Guard 之角色转换

1.1 简介 Data Guard配置包括1个primary角色的数据库和1个或者多个standby角色的数据库,数据库的角色我们可以通过V$DATABASE中DATABASE_ROLE字段来获得. 另外,Data Guard配置中standby库的数量.位置.备库类型以及redo data从主库传到备库的方式,决定了主库发生停机故障时能采用的角色管理方案. 当数据库运行于Data Guard中primary或者standby这样互斥的角色时,可以通过SQL语句或者Data Guard brok

Oracle 11g Data Guard 之物理备库角色转换

一.物理备库的Switchover操作 本节主要内容是物理备库的switchover操作,该操作起始于主库,结束于目标备库. 1.确认主库可以切换为standby角色 SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE; 如果结果显示TO STANDBY或者SESSIONS ACTIVE,则表明主库可以切换为standby角色,否则,切换操作将不可行,因为redo传输不是配置错误就是不能正常进行. 2.主库启动switchover 执行如下SQL语句将主库
