Oracle data guard 10g 搭建

1系统常规参数检查

硬盘

[[email protected] ~]# df -h

内核

[[email protected] ~]# uname -a

[[email protected] grs]# uname -a

版本

[[email protected] ~]# cat /etc/redhat-release

物理内存

[[email protected] ~]# grep MemTotal /proc/meminfo

虚拟内存

[[email protected] ~]# grep SwapTotal /proc/meminfo

主机名

[[email protected] ~]# hostname

ip地址

[[email protected] ~]# ifconfig

2.关闭防火墙服务iptables&SELinux安全策略&邮件服务 sendmail&时间同步服务 NTP

关闭防火墙服务

[[email protected] ~]# service iptables status

防火墙服务2345级别开机都启动

[[email protected] ~]#  chkconfig --list iptables

iptables        0:关闭  1:关闭  2:关闭  3:关闭  4:关闭  5:关闭  6:关闭

chkconfig iptables off                   关闭防火墙服务

关闭 SELinux安全策略

[[email protected] ~]# getenforce

a  永久关闭方法  –  需要重启服务器

修改/etc/selinux/config文件中设置 SELINUX=disabled  ，然后重启服务器

[[email protected] ~]# vi /etc/selinux/config

6 SELINUX=disabled

b  临时关闭方法  –  设置系统参数

使用命令 setenforce 0

setenforce 1  设置 SELinux  成为enforcing模式

setenforce 0  设置 SELinux  成为 permissive模式

[[email protected] ~]# setenforce 0

[[email protected] ~]# getenforce

Permissive

关闭邮件服务sendmail

[[email protected] ~]# service sendmail stop

service sendmail stop

chkconfig sendmail off

关闭 NTP时间同步服务

[[email protected] ~]# service ntpd status

ntpd is stopped

service ntpd stop

chkconfig --list ntpd

主库： ip：10.0.1.103

数据库sid：grs

Db_unique_name:grs

数据库安装路径：/u01/app/oracle/product/10.2.0/db_1

数据文件路径：/u01/app/oracle/oradata/grs/

本地归档路径：/u01/app/oracle/archivelog/

备库： ip：192.168.2.188

数据库sid：grsdg

Db_unique_name:grsdg

数据库安装路径：/mountdisk2/oracle/product/10.2.0/db_1

数据文件路径：/mountdisk2/oracle/oradata/grsdg/-----

/mountdisk2/oracle/oradata/grsdg

本地归档路径：/mountdisk2/oracle/archivelog/

2 准备工作

2.1 设置主库的force logging模式

SQL> conn /as sysdba

Connected.

SQL> select force_logging from v$database;

FOR

---

NO

SQL> alter database force logging;

Database altered.

SQL> select force_logging from v$database;

FOR

---

YES

alter database no force  logging

2.2确认主库的归档模式

SQL> archive log list;

Database log mode              Archive Mode

Automatic archival             Enabled

Archive destination            /u01/app/oracle/archivelog/

Oldest online log sequence     253

Next log sequence to archive   255

Current log sequence           255

如果是disable，需要启动到mount，

然后SQL> alter database archivelog;/noarchivelog

2.3创建主库密码文件(如果不存在的话)

[[email protected] ~]# cd /u01/app/oracle/product/10.2.0/db_1/dbs/

[[email protected] dbs]# ll

-rw-r----- 1 oracle oinstall    1536 03-24 15:55 orapwgrs

不存在就创建

$ orapwd file=orapwgrs password="987064" entries=10 force=y;

2.4配置主库standby redo log，并验证结果

SQL> alter database add standby logfile group 4 (‘/u01/app/oracle/oradata/grs/redo04.log‘) size 100m;

Database altered.

--删除该日志组

SQL> alter database drop standby logfile group 4;

Database altered.

SQL> alter database add standby logfile group 4 (‘/u01/app/oracle/oradata/grs/redo04.log‘) size 50m;

alter database add standby logfile group 4 (‘/u01/app/oracle/oradata/grs/redo04.log‘) size 50m

*

ERROR at line 1:

ORA-00301: error in adding log file ‘/u01/app/oracle/oradata/grs/redo04.log‘ -

file cannot be created

ORA-27038: created file already exists

Additional information: 1

--需要物理删除

----保证主库与备库的日志大小一样，

SQL> alter database add standby logfile group 4 (‘/u01/app/oracle/oradata/grs/redo04.log‘) size 50m;

Database altered.

SQL> alter database add standby logfile group 5 (‘/u01/app/oracle/oradata/grs/redo05.log‘) size 50m;

Database altered.

SQL> select group#, thread#, sequence#, archived, status from v$standby_log;

GROUP#    THREAD#  SEQUENCE# ARCHIV STATUS

---------- ---------- ---------- ------ --------------------

4          0          0 YES    UNASSIGNED

5          0          0 YES    UNASSIGNED

SQL> select group#,type,member from v$logfile;

GROUP# TYPE

---------- -------

--------------------------------------------------------------------------------

3 ONLINE

5.2分别启动主备库监听

为什么要先启动备库再启动主库呢？

DG 原理：主库启动后会主动探测备库，如果此时备库没有启动那么主库探测不到备库的存在，就会等待若干分钟之后再次探测，你会在 alert 日志中看到大量 ORA 报错引起恐慌，为了避免这种情况发生。可以先启动备库，此时备库会等待来自主库的日志，当备库启动之后主库再启动会在第一时间探测到备库存在，就不会看到大量报错信息了。

为什么在操作primary  standby 库时建议始终打开alert日志 这样可以实时监控数据库启动  关闭  切换  操作的状态，查看到日志是否应用，角色是否切换完毕，数据库是否read only 打开等，主要是为了方便我们监控主备库同步状态。

Oracle data guard 10g 搭建的相关文章

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 Data Guard

DG 是 Oracle Data Guard 的简称.也就是Oracle11g的 数据卫士. 由于在工作中 Oracle和 SQL SERVER2008 同时都需要维护管理.给我的感觉这里的 DG 其实和 Sql Server 2008的镜像实现的功能是一样的(当然更强大一些).DG 中的物理备用库 尤其和 Sql Server 2008 的镜像实现的功能是一样的.但也有不同点:DG中的物理备用库可以在特定条件下 以只读或读写方式打开.而镜像则不可以(2012版本虽然可以读,但还是不能打开),当

Oracle Data Guard broker 现场遇到bug ，闪之~

最近在客户现场搭建一套容灾环境,发现遇到了BUG,在无法解决的情况下,放弃了broker,依旧可以实现ADG,Oracle无法实现双主,但是MySQL可以哈.官网说法记录一下. OERR: ORA-16597 "Oracle Data Guard broker detects two or more primary databases" (varies by version) Reference Note (文档 ID 172973.1) PURPOSE This is a brief

YH1:Oracle Data Guard知识库

小编:大家对Oracle DataGuard 应该很熟吧? 众人:那是相当熟. 小编:好的,那我们今天就不讲基础知识了,直入主题!跟不上课的孩子自己回去补. 今天的话题包括: 12.2中ADG的性能与诊断 ADG上部署列式存储 DG跨平台迁移 DG数据恢复 DG的归档管理 12.2中ADG的性能与诊断 在Oracle 12.2中,ADG有许多惊人的改进,通过ADG standby数据库的性能数据收集和诊断.快照standby数据库的应用,以及实时的数据库操作监控的实现,能够根据用户需求相协调来提

Oracle Data Guard 概念篇

一个Data Guard 配置由一个生产库和一个或者多个standby数据库组成,在Data Guard配置中,主库和备库都既可以是rac环境,也可以是单机环境. 这篇文章主要介绍dataguard的一些基本知识 dataguard的分类.dataguard的服务类型.dataguard的保护模式 1.Dataguard中的备库分为物理备库和逻辑备库及快照备库 备库是主库的一致性拷贝,使用一个主库的备份可以创建多到30个备库,将其加入到dataguard环境中,创建成功后,dataguard通过

Oracle Data Guard 单实例到单实例配置(物理standby)

接上一篇oracle dataguard概念篇,现在进行下详细的配置,此次配置的是单实例到单实例,也就是说主库和备库都是基于文件系统的单实例. 主机环境:Red Hat Enterprise Linux Server release 6.3 Rdbms版本:11.2.0.3 其他详细信息如下所示: 需要注意的是,两边的/etc/hosts文件保证都包含对方的ip对应关系 oracle安装的目录是相同的 编辑/etc/hosts,分别添加以下内容 192.168.1.241 db1 192.168
