个人总结OLinux上安装oracle11G Data Guard

一、准备环境

1、swap要求

swap最好设置3G以上，如果安装过程中报swap不足，可参考：

本例子采用Oracle Linux自带的预装包实现：

详细参考：

https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1091

2.1. Installing the Oracle Preinstallation RPM or Oracle Validated RPM with ULN Support

操作系统安装后，使用oracle-rdbms-server-11gR2-preinstall包准备环境

https://docs.oracle.com/cd/E11882_01/install.112/e47689/pre_install.htm#LADBI1091

Start a terminal session and enter the following command as root, depending on your platform.

Oracle Linux :

# yum install oracle-rdbms-server-11gR2-preinstall

Oracle Linux  or Oracle Linux :

# yum install oracle-validated

You should see output indicating that you have subscribed to the Oracle Linux channel, and that packages are being installed. For example:

el5_u6_i386_base

el5_u6_x86_64_patch

Oracle Linux automatically creates a standard (not role-allocated) Oracle installation owner and groups, and sets up other kernel configuration settings as required for Oracle installations.

二、安装数据库软件

创建所需目录：

Oracle Base Directory:

[root@Oracle-A /]# mkdir -p /u01/app/oracle

Oracle Inventory Directory:
[root@Oracle-A /]# mkdir -p /u01/app/oraInventory

Oracle Home Directory:
[root@Oracle-A /]# mkdir -p /u01/app/oracle/product/11.2.0/db_1

可选：
Direcotories for Oracle DATA or Recovery Files:
[root@Oracle-A /]# mkdir -p /u01/oradata
[root@Oracle-A /]# mkdir -p /u01/fast_recovery_area
本例中使用默认的$oracle_base/flash_recovery_area

Software Installation Directories

You must specify the directory in which the Oracle Database software is installed, or the location where the product binary files are copied from the installation media. You must choose a location that has enough disk space to contain the software and is accessible by the operating system user performing the installation.

You also specify the location of the Oracle base directory, which is used by all Oracle software products installed on the server. The first time you install Oracle Database software on a server, you are prompted to specify the location of the inventory directory, called oraInventory. This directory provides a centralized inventory of all Oracle software products installed on the server. You should use the same value for the Oracle inventory directory each time you perform an Oracle software installation on the server.

文档中的目录说明

修改目录属性：

chown -R oracle.oinstalll /u01

修改环境变更

# vi /home/oracle/.bash_profile  #添加如下内容

ORACLE_BASE=/u01/app/oracle;

export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/11.2./db_1;

export ORACLE_HOME

ORACLE_SID=orcl;

export ORACLE_SID
LD_LIBRARY_PATH=$ORACLE_HOME/lib;
export LD_LIBRARY_PATH
PATH=$PATH:$ORACLE_HOME/bin:$HOME/bin;
export PATH

修改/etc/hosts文件

[root@Oracle-A tmp]# vi /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

:: localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.56.201 Oracle-A

上传安装文件

[root@Oracle-A tmp]# unzip p13390677_112040_Linux-x86-64_1of7.zip

[root@Oracle-A tmp]# unzip p13390677_112040_Linux-x86-64_2of7.zip

[root@Oracle-A tmp]# xhost +

[root@Oracle-A tmp]$ export DISPLAY=192.168.56.1:0.0

[oracle@Oracle-A 11.2.]$ cd /tmp/database/

配置xmanager

设置好连接后，在命令输入如下内容：

/usr/bin/xterm -ls -display $DISPLAY

用Xstart命令行中启动安装程序

成功后，调用出安装界面，忘记修改/etc/hosts/时，会报如下图的错误

安装过程，本例先安装软件，再创建数据库。

开始进行安装。

最后运行两个脚本

VirtualBox克隆另一台虚拟机

复制时候，选择重新初始化所有MAC地址

配置从库的主机信息。

删除UUID

如果网络不通，可以采取以下两种方法，我用的第1种，直接删除：

解决办法：

通过查看新VM的文件/etc/udev/rules.d/-persistent-net.rules，发现多了几个网卡接口，我们每更新一次网卡MAC地址，都只会在该文件内追加信息。我们有两种方法解决该问题：

. 删除70-persistent-net.rules文件，重启；

. 我们只需按照新VM的设置信息将70-persistent-net.rules文件内的多余网卡去掉，然后将正确MAC地址那一行改为对应于eth0即可，然后重启；

主库上创建数据库，发现不认dbca命令

oracle@edrsr12p1 Desktop]$ . oraenv

ORACLE_SID = [orcl] ? orcl

ORACLE_HOME = [/home/oracle] ? /u01/app/oracle/product/11.2./dbhome_1

The Oracle base remains unchanged with value /u01/app/oracle

[oracle@edrsr12p1 Desktop]$ dbca

修改Standby的环境变量

修改后正常：

字符集选择时，要慎重。

创建监听：

$netca,第一个listener一路回车即可。

完成安装后，开始安装物理DATAGuard，先调整主库

1、Enable force logging

SQL> alter database force logging;

Database altered.

SQL> select force_logging from v$database;

FOR
---
YES

2、查询当前日志组和文件分布并创建转化为备库时使用的redo log文件，要求Standby redo log的组数要多于online redo log，并且二者的日志文件大小相同。

SQL> col member format a50

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

    GROUP# MEMBER

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

          /u01/app/oracle/oradata/orcl/redo03.log

          /u01/app/oracle/oradata/orcl/redo02.log

          /u01/app/oracle/oradata/orcl/redo01.log

SQL> select group#,bytes/(1024*1024) from v$log;

GROUP# BYTES/(1024*1024)
---------- -----------------
1 50
2 50
3 50

SQL> alter database add standby logfile
2 group 4 '/u01/app/oracle/oradata/orcl/std_redo04.log' size 50m;

Database altered.

SQL> alter database add standby logfile
2 group 5 '/u01/app/oracle/oradata/orcl/std_redo05.log' size 50m;

Database altered.

SQL> alter database add standby logfile
2 group 6 '/u01/app/oracle/oradata/orcl/std_redo06.log' size 50m;

Database altered.

SQL> alter database add standby logfile
2 group 7 '/u01/app/oracle/oradata/orcl/std_redo07.log' size 50m;

Database altered.

查看一下当前的redo log

SQL> select member from v$logfile;

MEMBER
--------------------------------------------------
/u01/app/oracle/oradata/orcl/redo03.log
/u01/app/oracle/oradata/orcl/redo02.log
/u01/app/oracle/oradata/orcl/redo01.log
/u01/app/oracle/oradata/orcl/std_redo04.log
/u01/app/oracle/oradata/orcl/std_redo05.log
/u01/app/oracle/oradata/orcl/std_redo06.log
/u01/app/oracle/oradata/orcl/std_redo07.log

注：Standby redo log 的组数参考公式：(online redolog级数+1)*数据库线程数，RAC线程为2.

Standby redolog的组成员数和大小也尽量和online redo一样。

设置主库初始化参数

SQL> create pfile from spfile;

File created.

SQL> !

[oracle@Oracle-A bin]$ ls -l $ORACLE_HOME/dbs

total

-rw-rw----  oracle oinstall  Jun  : hc_orcl.dat

-rw-r--r--  oracle oinstall  May    init.ora

-rw-r--r-- 1 oracle oinstall  938 Jun 23 15:43 initorcl.ora #新创建的

-rw-r-----  oracle oinstall    Jun  : lkORCL

-rw-r-----  oracle oinstall  Jun  : orapworcl

-rw-r-----  oracle oinstall  Jun  : spfileorcl.ora

编辑这个生成的初始化参数文件

查看归档的路径：

Oracle11g版本，ORACLE默认的日志归档路径为闪回恢复区（$ORACLE_BASE/fast_recovery_area）。对于这个路径，Oracle有一个限制，就是默认只有4G的空间，而且不只是归档日志的默认路径，也是备份文件和闪回日志的默认地址，这样的话归档日志锁使用的空间就达不到4G，在没有设置好这个路径大小的情况下，很多系统都遇到过归档日志满而无法归档导致数据库夯住的问题。

归档路径说明

SQL> archive log list;

Database log mode              Archive Mode

Automatic archival             Enabled

Archive destination            USE_DB_RECOVERY_FILE_DEST

Oldest online log sequence

Next log sequence to archive

Current log sequence

这里可以看到Archive destination的值为USE_DB_RECOVERY_FILE_DEST，可以理解为USE(使用)DB_RECOVERY_FILE_DEST这个路径

查看DB_RECOVERY_FILE_DEST路径

SQL> show parameter db_recovery;

NAME                                 TYPE        VALUE

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

db_recovery_file_dest                string      /u01/app/oracle/fast_recovery_area

db_recovery_file_dest_size           big integer 4182M

下面的参数是空的

SQL> show parameter log_archive_dest_1;

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_1 string
log_archive_dest_10 string
log_archive_dest_11 string
log_archive_dest_12 string
log_archive_dest_13 string
log_archive_dest_14 string
log_archive_dest_15 string
log_archive_dest_16 string
log_archive_dest_17 string
log_archive_dest_18 string
log_archive_dest_19 string

由上可以很清楚的看到DB_RECOVERY_FILE_DEST路径参数的值默认为/u01/oracle/fast_recovery_area，并且Oracle设置的大小为4G。
默认情况下，归档日志会存放到闪回恢复区（$ORACLE_BASE/fast_recovery_area）内，如果闪回恢复区已经使用到4G，归档日志就有可能无法继续归档，数据库夯住。

具体参考：https://blog.csdn.net/u011364306/article/details/49276717

vi /u01/app/oracle/product/11.2./db_1/dbs/initorcl.ora

以下为增加内容:

log_archive_config='dg_config=(orcl,orclstdby)'
log_archive_dest_1='location=/u01/app/oracle/fast_recovery_area valid_for=(all_logfiles,all_roles) db_unique_name=orcl'
log_archive_dest_2='service=orclstdby lgwro async valid_for=(online_logfiles,primary_roles) db_unique_name=orclstdby' #lgwro async选一
log_archive_dest_state_1=enable
log_archive_dest_stat_2=enable
db_file_name_convert='/u01/app/oracle/oradata/orclstdby','/u01/app/oracle/oradata/orcl'
log_file_name_convert='/u01/app/oracle/oradata/orclstdby','/u01/app/oracle/oradata/orcl'
fal_server=orclstdby
fal_client=orcl
standby_file_management=auto
standby_archive_dest='/u01/app/oracle/fast_recovery_area'

比原文少了创建相关archive log的目录，这里临时使用默认路径，有问题，后面再修改。

shutdown 实例

SQL> shutdown immediate;

Database closed.

Database dismounted.

ORACLE instance shut down.

测试一下参数文件：

SQL> startup pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initorcl.ora';

再shutdown实例

启动到mount状态：

SQL> startup mount pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initorcl.ora';

在主库上创建备库的控制文件

SQL> alter database create standby controlfile as '/u01/app/oracle/oradata/orcl/orclstdby01.ctl';

在备库上创建对应目录，如backup、归档目录，本例为闪回下，control文件存放目录，并将相应文件复制过去

cd /u01/app/oracle/oradata/

mkdir -p orclstdby

scp initorcl.ora oracle@192.168.56.202:/u01/app/oracle/product/11.2./db_1/dbs/initorclstdby.ora

scp /u01/app/oracle/oradata/orcl/orclstdby01.ctl oracle@192.168.56.202:/u01/app/oracle/oradata/orclstdby/

scp orapworcl oracle@192.168.56.202:/u01/app/oracle/product/11.2./db_1/dbs/

[oracle@Oracle-A dbs]$ scp -r /u01/app/oracle/fast_recovery_area/ORCL oracle@192.168.56.202:/u01/app/oracle/fast_recovery_area/orclstdby/

经过一系列的目录对比、复制文件、修改参数文件后，终于可以把备库启动到Mount状态

对备库的参数文件再次修改，控制文件名的名称，不符合：

*.control_files='/u01/app/oracle/oradata/orclstdby/orclstdby01.ctl','/u01/app/oracle/fast_recovery_area/orclstdby/orclstdby02.ctl'

创建主库和备库的监听，可用图形界面或直接编辑listener.ora

编辑Net service names,主库和备份库复制即可，监听也折腾了一段时间，图形创建的可以，而手工编辑按文档的不行，后用图形配置后，进行了些更改，OK!

主库的监听配置文件
$cd /u01/app/oracle/product/11.2./db_1/network/admin

[oracle@Oracle-A admin]$ cat listener.ora

ADR_BASE_LISTENER = /u01/app/oracle

备库的listener.ora

编辑tnsnames.ora

[oracle@Oracle-A admin]$ cat tnsnames.ora

orcl =

  (DESCRIPTION=

从我这边实际情况看，把复制过来的orapworcl复制一个备库的实例名的密码文件，故障排除。

cp /u01/app/oracle/product/11.2.0/db_1/dbs/orapworcl /u01/app/oracle/product/11.2.0/db_1/dbs/orapworclstdby

校验命令：

SELECT STATUS, GAP_STATUS FROM V$ARCHIVE_DEST_STATUS WHERE DEST_ID = 2;

角色切换

Data Guard provides the V$DATAGUARD_STATS view that can be used to evaluate each standby database in terms of the currency of the data in the standby database, and the time it will take to perform a role transition if all available redo data is applied to the standby database. For example:

SQL> COLUMN NAME FORMAT A24

SQL> COLUMN VALUE FORMAT A16

SQL> COLUMN DATUM_TIME FORMAT A24

SQL> SELECT NAME, VALUE, DATUM_TIME FROM V$DATAGUARD_STATS;

NAME                     VALUE            DATUM_TIME

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

transport lag            +00 00:00:00     06/18/2009 12:22:06

apply lag                +00 00:00:00     06/18/2009 12:22:06

apply finish time        +00 00:00:00.000

estimated startup time   9

This query output shows that the standby database has received and applied all redo generated by the primary database. These statistics were computed using data received from the primary database as of 12:22.06 on 06/18/09.

If a standby database currently running in maximum protection mode will be involved in the failover, first place it in maximum performance mode by issuing the following statement on the standby database:

SQL> ALTER DATABASE SET STANDBY DATABASE TO MAXIMIZE PERFORMANCE;

Query the SWITCHOVER_STATUS column of the V$DATABASE view on the primary database.For example:

SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE;

SWITCHOVER_STATUS

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

 TO STANDBY

 1 row selected

Issue the following SQL statement on the target physical standby database:

SQL> ALTER DATABASE COMMIT TO SWITCHOVER TO PRIMARY WITH SESSION SHUTDOWN;

Open the new primary database.

SQL> ALTER DATABASE OPEN;

Start Redo Apply on the new physical standby database.

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE  DISCONNECT FROM SESSION;

Restart Redo Apply if it has stopped at any of the other physical standby databases in your Data Guard configuration.

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT FROM SESSION;

故障处理一

ORA-02253:an incompatible media recovery is active

天在standby 数据库上执行

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

报如下错误：

ERROR at line 1:

ORA-01153: an incompatible media recovery is active

从字面意思理解应该是“存在一个不兼容的介质恢复”。

仔细检查发现上面已经执行过一次

alter database  recover managed standby database disconnect from session; 

猜想应该是重复启用日志应用所致。故取消应用

alter database recover managed standby database cancel;

重新开启应用

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

问题解决，没有报错。
