一步一步实现 oracle data guard

一步一步实现oracle data guard。

Oracle data guard 的实施目标,将主机 guohuiorcl2(IP 192.168.31.128)上的oracle archivelog日志传输到 主机 guohuiorcl1(IP 192.168.31.129)上。

期间用到的主机如下

一步一步实现 oracle data guard_第1张图片

 

 

1、主机guohuilinuxas31

rman 备份管理服务器,在其上建立 rman catalog,对其他主机进行rman 备份与恢复。

操作系统环境 Linux ES3-U9

IP 192.168.31.130

Netmark 255.255.255.0

Getway 192.168.31.1

主机名 guohuilinuxas31

实例名 orcl

Oracle 版本:Oracle Database 10gEnterprise Edition Release 10.2.0.1.0

主机 guohuiorcl1

 

 

2、备用数据库

操作系统环境 Linux ES5.4

IP 192.168.31.129

Netmark 255.255.255.0

Getway 192.168.31.1

主机名 guohuiorcl1

实例名 orcl

Oracle 版本:Oracle Database 10gEnterprise Edition Release 10.2.0.1.0

主机 guohuiorcl2

 

 

3、主用数据库

操作系统环境 Linux ES5.4

IP 192.168.31.128

Netmark 255.255.255.0

Getway 192.168.31.1

主机名 guohuiorcl2

实例名 orcl

Oracle 版本:Oracle Database 10gEnterprise Edition Release 10.2.0.1.0

 

准备主用数据库的环境变量

主机 guohuiorcl2 oracle 用户环境

[oracle@guohuiorcl2 ~]$ cat .bash_profile

# .bash_profile

# Get the aliases and functions

if [ -f ~/.bashrc ]; then

        . ~/.bashrc

fi

# User specific environment and startup programs

TMP=/tmp;export TMP

TMPDIR=$TMP;export TMPDIR

ORACLE_BASE=/home/oracle/oracle;export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1;export ORACLE_HOME

ORACLE_SID=orcl;export ORACLE_SID

ORACLE_TERM=xterm;export ORACLE_TERM

PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin

export PATH=$PATH:/sbin

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;

export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;export CLASSPATH

if [$USER = "oracle"]; then

  if [$SHELL = "bin/ksh"]; then

    ulimit -p 16384

    ulimit -n 65536

  else

    ulimit -u 16384 -n 65536

  fi

fi

ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1;export ORACLE_HOME

#xhost local:oracle

 

第一步:检查主用数据库 guohuiorcl2 上的oracle 是否开启了archive 。

在 主机 guohuilinuxas31 上建立rman 的恢复管理目录,准备把 guoorcl2 上的 orcl 数据库备份到 guohuilinuxas31 ,再恢复到 guoorcl1 上

以上指令在rman主机guohuilinuxas31上创建了rman账户。

在主机guohuilinuxas31上添加主用数据库 guohuiorcl2上oracle的tns链接

[oracle@guohuilinuxas31 network]$

在主机guohuilinuxas31上注册主机 guohuiorcl2的oracle为目标数据库

首先改掉主机guohuilinuxas31上 的 .bash_profile 的path变量参数,因为linux有自己的rman指令,会卡住oracle的rman,把oracle的 指令目录前置。

PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin;export PATH

改成

PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin;export PATH

然后 [oracle@guohuilinuxas31 oracle]$ source .bash_profile

让修改的参数生效。

验证一下:

要求安装备用数据库的oracle 的主机 guohuiorcl1的主机分区环境和oracle相关的目录结构和主机 guohuiorcl2的完全相同。其实这个不是强制要求,只是这样做比较省事。否则,需要改pfile.ora 文件,把恢复主机所在目录结构改到 pfile.ora 里面。

修改备用数据库guohuiorcl1的 环境变量与主用数据库 guohuiorcl2的完全相同。这样搞比较省事,真实的生产环境如果相同,两个库更容易管理。

主用数据库 guohuiorcl2的环境如下:

# .bash_profile

# Get the aliases and functions

        . ~/.bashrc

主用数据库 guohuiorcl2 与 备用数据库 guohuiorcl1 的关于oracle的环境是一样的。其他的环境变量,稍有不同,但不影响我们做data guard。

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

 

创建主机guohuiorcl1备用数据库的参数文件

因为guoorcl1上已经安装过一个可以启动的orcl实例,所有有这个pfile.ora文件,如果guoorcl1上只是安装了软件,就需要重guoorcl2上把 pfile.ora 或者 spfile.ora 文件给传过了,而且还得改这个文件。

备用数据库进入到后台管理恢复状态

采用Lgwr进程传递联日志机的最大性能模式

1. 在备用数据库上创建备用日志

(

alter database recover managed standby database cancel;

alter database add standby LOGFILE GROUP 5 ('/home/oracle/oracle/oradata/orcl/stdy_redo05.log') size 10m;

alter database add standby LOGFILE GROUP 6 ('/home/oracle/oracle/oradata/orcl/stdy_redo06.log') size 10m;

alter database add standby LOGFILE GROUP 7 ('/home/oracle/oracle/oradata/orcl/stdy_redo07.log') size 10m;

alter database add standby LOGFILE GROUP 8 ('/home/oracle/oracle/oradata/orcl/stdy_redo08.log') size 10m;

alter database recover managed standby database disconnect from session;

)

SQL> alter database recover managed standby database cancel;

Database altered.

SQL> alter database add standby LOGFILE GROUP 5 ('/home/oracle/oracle/oradata/orcl/stdy_redo05.log') size 10m;

Database altered.

SQL> alter database add standby LOGFILE GROUP 6 ('/home/oracle/oracle/oradata/orcl/stdy_redo06.log') size 10m;

Database altered.

SQL> alter database add standby LOGFILE GROUP 7 ('/home/oracle/oracle/oradata/orcl/stdy_redo07.log') size 10m;

Database altered.

SQL> alter database add standby LOGFILE GROUP 8 ('/home/oracle/oracle/oradata/orcl/stdy_redo08.log') size 10m;

Database altered.

SQL> alter database recover managed standby database disconnect from session;

Database altered.

2. 修改主库的归档路径

alter system set LOG_ARCHIVE_DEST_2='SERVICE=orclsby1 LGWR' scope=both;

另外,如果考虑到以后该库可能被切换到备用数据库,也可以创建同样的备用日志

组:

alter database add standby LOGFILE GROUP 5 ('/home/oracle/oracle/oradata/orcl/stdy_redo05.log') size 10m;

alter database add standby LOGFILE GROUP 6 ('/home/oracle/oracle/oradata/orcl/stdy_redo06.log') size 10m;

alter database add standby LOGFILE GROUP 7 ('/home/oracle/oracle/oradata/orcl/stdy_redo07.log') size 10m;

alter database add standby LOGFILE GROUP 8 ('/home/oracle/oracle/oradata/orcl/stdy_redo08.log') size 10m;

四、验证备用服务器是否工作

在备库中查看日志

SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

在主库中执行

alter system switch logfile;

在备库中查看日志是否被传送过来

SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

备用数据库查询

SQL> SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

 SEQUENCE# FIRST_TIM NEXT_TIME APP

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

         5 15-APR-11 16-APR-11 YES

         6 16-APR-11 16-APR-11 YES

         7 16-APR-11 16-APR-11 YES

         8 16-APR-11 16-APR-11 YES

         9 16-APR-11 16-APR-11 YES

        10 16-APR-11 17-APR-11 YES

        11 17-APR-11 29-APR-11 YES

        12 29-APR-11 29-APR-11 YES

        13 29-APR-11 01-MAY-11 YES

        14 01-MAY-11 01-MAY-11 YES

10 rows selected.

主用数据库执行

alter system switch logfile;

在备库中查看日志是否被传送过来

SQL> alter system switch logfile;

System altered.

执行时间明显变长,因为要传输日志。

备用数据库查询

SQL> SELECT SEQUENCE#, FIRST_TIME, NEXT_TIME, APPLIED FROM V$ARCHIVED_LOG ORDER BY SEQUENCE#;

 SEQUENCE# FIRST_TIM NEXT_TIME APP

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

         5 15-APR-11 16-APR-11 YES

         6 16-APR-11 16-APR-11 YES

         7 16-APR-11 16-APR-11 YES

         8 16-APR-11 16-APR-11 YES

         9 16-APR-11 16-APR-11 YES

        10 16-APR-11 17-APR-11 YES

        11 17-APR-11 29-APR-11 YES

        12 29-APR-11 29-APR-11 YES

        13 29-APR-11 01-MAY-11 YES

        14 01-MAY-11 01-MAY-11 YES

        15 01-MAY-11 01-MAY-11 YES

11 rows selected.

 可以看到,日志已从guohuiorcl2传输到guohuiorcl1.至此,oracle 的 data guard 配置完毕。
