2.2 用户的准备工作(BXDB1和BXDB2相同)

  • 修改UDP参数
$ vi /etc/rc2.d/S99ndd

添加

ndd -set /dev/udp udp_xmit_hiwat 65536
ndd -set /dev/udp udp_recv_hiwat 65536
  • 建立所需的组
/usr/sbin/groupadd -g 1000 oinstall
/usr/sbin/groupadd -g 1100 asmadmin
/usr/sbin/groupadd -g 1200 dba
/usr/sbin/groupadd -g 1201 oper
/usr/sbin/groupadd -g 1300 asmdba
/usr/sbin/groupadd -g 1301 asmoper
  • 建立所需的用户
# mkdir -p /export/home/grid
# useradd -u 1100 -g oinstall -G dba,asmadmin,asmdba,asmoper -d /export/home/grid -s /usr/bin/bash grid

# mkdir -p /export/home/oracle
# useradd -u 1101 -g oinstall -G asmdba,dba,oper -d /export/home/oracle -s /usr/bin/bash  oracle

修改新建用户的密码 密码1qaz.oracle

# passwd grid
# passwd oracle
  • 修改环境变量

Grid用户

# su – grid
$ vi .profile

添加

# ORACLE_SID (节点2上要写ORACLE_SID=+ASM2)

ORACLE_SID=+ASM1; export ORACLE_SID
ORACLE_BASE=/oracle/app/grid; export ORACLE_BASE
ORACLE_HOME=/oracle/app/11.2.0/grid; export ORACLE_HOME
PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH
NLS_LANG=AMERICAN_AMERICA.UTF8;export NLS_LANG
umask 022

oracle用户

# su – oracle
$ vi .profile

添加

# ORACLE_SID (节点2上要写ORACLE_SID=boss2)

ORACLE_SID=boss1; export ORACLE_SID
ORACLE_BASE=/oracle/app/oracle; export ORACLE_BASE
ORACLE_HOME=/oracle/app/oracle/product/11.2.0/dbhome_1; export ORACLE_HOME
PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin
PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH
NLS_LANG=AMERICAN_AMERICA.UTF8;export NLS_LANG
umask 022
  • 修改系统参数(root用户)
# vi /etc/system

添加

set noexec_user_stack=1
set semsys:seminfo_semmni=100
set semsys:seminfo_semmns=1024
set semsys:seminfo_semmsl=256
set semsys:seminfo_semvmx=23767
set shmsys:shminfo_shmmax=107374182400
set shmsys:shminfo_shmmin=1
set shmsys:shminfo_shmmni=100
set shmsys:shminfo_shmset=10

执行

# projmod -sK "project.max-shm-memory=(privileged,100G,deny)" default

重启服务器

  • 配置等效性

以下是grid用户,oracle用户配置方式一样

$ chmod 755 /export/home (该目录权限必须是755)

◆以下两个RAC节点都执行

-bash-3.00$ mkdir -p ~/.ssh
-bash-3.00$ chmod 700 ~/.ssh
-bash-3.00$ /usr/bin/ssh-keygen -t rsa

提示输入输入密码时,保持为空回车即可,使用空密码操作简单一些。

◆以下只在RAC节点1执行

-bash-3.00$ touch ~/.ssh/authorized_keys
-bash-3.00$ ssh BXDB1 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
-bash-3.00$ ssh BXDB2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
-bash-3.00$ scp ~/.ssh/authorized_keys BXDB2:.ssh/authorized_keys

◆以下两个RAC节点都执行

-bash-3.00$ chmod 600 ~/.ssh/authorized_keys

测试等效性,不提示输入密码即配置成功(第一次要求输入密码是正常的)

ssh BXDB1 "date;hostname"
ssh BXDB2 "date;hostname"
  • 配置裸盘(root用户)

依次将要使用的盘全部格式化分区完毕

  • 修改磁盘权限

在划分磁盘时若选择了将空间分配给n号片,对应的盘片就是sn,例如磁盘是c0t600000E00D11000000111430000D0000d0,空间分配到了6号片,最终我们使用的磁盘文件名就是c0t600000E00D11000000111430000D0000d0s6

chown grid:asmadmin /dev/rdsk/c0t600000E00D11000000111430000D0000d0s6
chown grid:asmadmin /dev/rdsk/c0t600000E00D1100000011143000030000d0s6
chown grid:asmadmin /dev/rdsk/c0t600000E00D1100000011143000020000d0s6
chown grid:asmadmin /dev/rdsk/c0t600000E00D1100000011143000010000d0s6
chown grid:asmadmin /dev/rdsk/c0t600000E00D1100000011143000000000d0s6

img

提示以下条件不满足,这两个错误可以忽略

img

确认无误开始安装

img

安装完毕按提示在两个节点分别以root用户执行脚本

img

安装完毕后在检验cluster状态时报错,这是因为我们没有配置DNS服务器来分配VIP和SCANip,而是通过手动分配,该错误可以忽略,至此cluster软件安装完毕

img

3.2 安装database软件(BXDB1上)

  • 以 grid 用户运行安装程序

# xhost +

# 解压安装软件

# su – grid

$ export DISPLAY=客户机ip:0.0

$ ./runInstaller

选择只安装数据库软件

img

选择集群模式安装

img

点击ssh connectivity配置用户等效性

img

img

添加中文语言

img

选择安装企业版

img

选择安装目录,由于根目录属于grid用户,因此在两个节点都手动建好该目录,并将权限和属组赋给oracle用户

mkdir -p /oracle/app/oracle

chown oracle:oinstall /oracle/app/oracle

img

选择安装软件组

img

检查系统环境是否满足安装要求

img

以下错误可以忽略

img

检查无误开始安装

img

安装完毕,按提示以root用户在两个节点执行脚本即可

img

执行相应脚本完成安装

img

3.3 创建数据库

  • 以 grid 用户建立ASM磁盘组

# xhost +

# su – grid

$ export DISPLAY=客户机ip:0.0

$ asmca

按照下图建立磁盘组,其中CRS是在安装CRS软件时已经建立的

img

  • 以 oracle 用户建立集群数据库

# xhost +

# su – oracle

$ export DISPLAY=客户机ip:0.0

$ dbca

选择集群数据库

img

选择建立数据库

img

选择自定义数据库

img

根据实际情况输入数据库名,勾选所有节点

img

选择配置EM

img

为用户配置密码,这里密码全部为1qaz.oracle,若提示密码不够安全,点击yes即可

img

选择数据文件存储方式,选择ASM,并填入之前建好的磁盘组名,会要求输入ASMSNMP密码,输入1qaz.oracle即可

img

配置快速恢复区,选择之前建好的ASM磁盘组,填入大小,这里是900g,勾选激活归档

img

去除不必要的组件

img

配置内存大小,勾选自动内存管理,该值可以在建完库后根据实际情况修改

img

配置块大小和连接数

img

配置字符集,选择AL32UTF8

img

按照默认选择专有模式即可

img

配置数据文件,每个节点分配4组,将redo大小改为512M

img

确认无误开始建库

img

开始建库

img

至此数据库安装完毕

4 常用维护命令

4.1 启动和关闭集群

(1) 启动集群件和集群数据库

集群系统默认是自动启动的,手工启动集群件的命令是:

-bash-3.00# cd /u01/app/11.2.0/grid/bin (root用户**)**

-bash-3.00# ./crsctl start cluster

也可以以下命令(在11.2版本中不建议使用),以grid用户执行

-bash-3.00# su - grid

-bash-3.00$ crs_start -all

启动集群数据库

-bash-3.00$ su - oracle

-bash-3.00$ srvctl start database -d racdb (启动全部实例节点)

-bash-3.00$ srvctl start instance -d racdb -n racdb1 (节点1上启动数据库实例**)**

-bash-3.00$ srvctl start instance -d racdb -n racdb2 (节点2上启动数据库实例**)**

(2) 关闭RAC集群数据库和集群件

先关闭集群数据库

-bash-3.00$ su - oracle

-bash-3.00$ srvctl stop database -d racdb

再关闭集群件(root用户)

-bash-3.00$ su -

-bash-3.00# cd /u01/app/11.2.0/grid/bin

-bash-3.00# ./crsctl stop cluster

4.2 RAC常用命令

集群系统的维护主要使用srvctl命令就可以完成,我们可以使用帮助命令来查看其使用,在oracle用户下执行 srvctl -help 来查看帮助信息

-bash-3.00# su - oracle

-bash-3.00$ srvctl -help

Usage: srvctl []

commands: enable|disable|start|stop|relocate|status|add|remove|modify|getenv|setenv|unsetenv|config

objects: database|instance|service|nodeapps|vip|asm|diskgroup|listener|srvpool|server|scan|scan_listener|oc4j|home|filesystem|gns

For detailed help on each command and object and its options use:

srvctl -h or

srvctl -h

该命令的格式和用法都列出来了,继续查看具体用法就在命令和对象的后面加 -h 参数,这样一层一层的查看帮助就可以得到全部的使用方法而不用查看其它的资料。

-bash-3.00$ srvctl add -h (给集群添加对象,比较重要的如:service, srvpool等等)

-bash-3.00$ srvctl remove -h (删除集群的对象)

-bash-3.00$ srvctl modify -h (修改集群的对象)

-bash-3.00$ srvctl config -h (查看集群内对象的配置信息)

-bash-3.00$ srvctl status -h (查看集群内对象的状态信息)

-bash-3.00$ srvctl relocate -h (把集群的对象重定位到其它实例节点,如oc4j, gns只在一个实例节点上有效,使用该命令可以把对象转移到其它实例节点)

-bash-3.00$ srvctl enable -h (把集群内已经存在的对象置于可用状态)

-bash-3.00$ srvctl disable -h (把集群内已经存在的对象置于不可用状态)

-bash-3.00$ srvctl start -h (启动集群内已经存在的对象)

-bash-3.00$ srvctl stop -h (停止集群内已经存在的对象)

常用的比如:

◆查看全部安装集群数据库名称

-bash-3.00$ srvctl config database

racdb

◆查看指定的集群数据库的配置信息

-bash-3.00$ srvctl config database -d racdb

Database unique name: racdb

Database name: racdb

ONS daemon exists. Local port 6100, remote port 6200

eONS daemon exists. Multicast port 16717, multicast IP address 234.92.69.133, listening port 2016

◆列出集群中所有运行的实例

-bash-3.00$ sqlplus / as sysdba

SQL> col host format a10

SQL> col db_status format a8

SQL> col inst_name format a8

SQL> SELECT inst_id, instance_number inst_no, instance_name inst_name,
