Oracle 10g & ASM Install For Redhat Enterprise Linux AS 4

一、系统调整

1.检查操作系统rpm包安装情况

binutils-2.15.92.0.2-13.EL4

compat-db-4.1.25-9

compat-libstdc++-296-2.96-132.7.2

control-center-2.8.0-12

gcc-3.4.3-22.1.EL4

gcc-c++-3.4.3-22.1.EL44

glibc-2.3.4-2.9

glibc-common-2.3.4-2.9

gnome-libs-1.4.1.2.90-44.1

libstdc++-3.4.3-22.1

libstdc++-devel-3.4.3-22.1

make-3.80-5

pdksh-5.2.14-30

sysstat-5.0.5-1

xscreensaver-4.18-5.rhel4.2

setarch-1.6-1

注:

检测——rpm–qamake

安装——rpm–Uvhmake-3.80-5.i386.rpm

2.配置Linux内核参数

1)打开/etc/sysctl.conf,添加以下参数：

kernel.shmall=2097152

kernel.shmmax=2147483648

kernel.shmmni=4096

kernel.sem=25032000100128

fs.file-max=65536

net.ipv4.ip_local_port_range=102465000

net.core.rmem_default=262144

net.core.rmem_max=262144

net.core.wmem_default=262144

net.core.wmem_max=262144

2)运行下面命令，使参数生效：

#/sbin/sysctl-p

3.在/etc/security/limits.conf文件中添加如下信息

* soft nproc 2047

* hard nproc 16384

* soft nofile 1024

* hard nofile 65536

4.在/etc/pam.d/login文件中加入下列行

sessionrequired/lib/security/pam_limits.so

5.建用户组与用户

#groupaddoinstall

#groupadddba

#useradd-m-u501-goinstall-Gdbaoracle

#passwdoracle

6.创建文件夹并设置属主

#mkdir/oracle

#chown-Roracle:dba/oracle

7.在/home/oracle/.bash_profile文件中加入如下内容，增加环境变量

exportORACLE_BASE=/oracle

exportORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1

exportORACLE_SID=ora10gdb

exportORACLE_TERM=xterm

PATH=/usr/sbin:$PATH;exportPATH

PATH=$ORACLE_HOME/bin:$PATH;exportPATH

if[$USER="oracle"];then

if[$SHELL="/bin/ksh"];then

ulimit-p16384

ulimit-n65536

else

ulimit-u16384-n65536

fi

fi

二、安装Oracle软件

1.#/media/cdrom/runInstaller,GUI启动后,选择“高级安装”，下一步。

2.安装100%时，会弹出对话框，要求运行两个脚本。

3.以root用户登陆Linux系统，按要求运行脚本，中间localbin路径直接回车，运行完后，点对话框的“确定”。

4.安装完成

三、自动存储ASM配置

1.安装OracleASMLib需要的安装包

oracleasm-2.6.9-78.EL-debuginfo-2.0.5-1.el4.i686.rpm

oracleasm-support-2.1.1-1.el4.i386.rpm

oracleasm-2.6.9-78.EL-2.0.5-1.el4.i686.rpm

oracleasmlib-2.0.2-1.i386.rpm

oracleasm-2.6.9-78.ELsmp-2.0.5-1.el4.i686.rpm

oracleasm-2.6.9-78.ELhugemem-2.0.5-1.el4.i686.rpm

oracleasm-2.6.9-78.ELxenU-2.0.5-1.el4.i686.rpm

2. 配置ASMLib
# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]

3. 创建ASM磁盘
说明：createdisk 是针对分区,不是针对磁盘,即:先应将磁盘分区
1) 对硬盘进行分区操作
# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device BootStartEndBlocksId System
/dev/sda1* 1 1310439183 Linux
……
Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device BootStartEndBlocksId System

Disk /dev/sdc: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device BootStartEndBlocksId System
# fdisk /dev/sdb

# fdisk -l

255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device BootStartEndBlocksId System
/dev/sda1* 1 1310439183 Linux
……
Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device BootStartEndBlocksId System
/dev/sdb11130 1044193+ 83 Linux
Disk /dev/sdc: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device BootStartEndBlocksId System

2) 将分区加入到ASM磁盘中
# oracleasm createdisk ASMVOL1 /dev/sdb1
Writing disk header: done
Instantiating disk: done
# oracleasm createdisk ASMVOL2 /dev/sdc1
Writing disk header: done
Instantiating disk: done

3) 查看ASM磁盘信息
# oracleasm listdisks
ASMVOL1
ASMVOL2

注：

删除ASM磁盘——#/etc/init.d/oracleasmdeletediskVOL4

RAC环境中某节点添加新ASM磁盘,其它节点运行scandisk来获取这种变化——#/etc/init.d/oracleasmscandisks

四、建立数据库

$dbca

1.启动数据库新建界面，“下一步”。

2.保持默认，至存储选项时，选择“自动存储管理（ASM）”，点“下一步”。

3.弹出警告对话框，要求启动CSS。

4.按要求以root身份登陆Linux系统，运行命令完成后回到对话框点“确定”。

5.输入ASM实例口令，并确认，“下一步”。

6.数据库开始创建ASM实例，并启动。

7.ASM实例完成后，准备创建并加载ASM磁盘组。点击“新建”。

8.此处为磁盘组命名，选择冗余方案，选择欲加入磁盘组的分区后点“确定”。

9.磁盘组加载完成后，开始建立数据库。

10.数据库建立完成。

11.数据库建立完成后，进行用户与密码管理。

五、ASMdatabase简单管理

1.开机启动:

1)启动监听

$lsnrctlstart

2)启动ASM实例

$exportORACLE_SID=+ASM

$sqlplus/assysdba

注：CSS必需已启动，可用crsctlcheckcss命令查看

SQL>startup

3)启动数据库

$exportORACLE_SID=ctais

$sqlplus/assysdba

SQL>startup

2.关机停止:

1)关闭数据库

$exportORACLE_SID=ctais

$sqlplus/assysdba

SQL>shutdownimmediate

2)关闭ASM实例

$exportORACLE_SID=+ASM

$sqlplus/assysdba

SQL>shutdownimmediate
