1.修改参数：

vi /etc/selinux/config

SELINUX=disabled

[root@www oracle]# tail -n 6 /etc/security/limits.conf

oracle              soft    nproc   2047

oracle              hard    nproc   16384

oracle              soft    nofile  1024

oracle              hard    nofile  65536

oracle              soft    stack   1024

vi /etc/pam.d/login

# pam_selinux.so open should only be followed by sessions to be executed in the user context

session    required     pam_selinux.so open

session    required     pam_limits.so

Enabling Core File Creatio:

/etc/profile        ulimit –S –c 0 > /dev/null 2>&1   ==> ulimit -S -c unlimited > /dev/null 2>&

vi /etc/sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 1024 65500

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 104858

kernel.core_uses_pid = 1

fs.suid_dumpable = 1

使用/sbin/sysctl -p命令来让系统参数修改生效

2.模拟操作系统版本降级(欺骗oracle)：

vi /etc/redhat-release

Red Hat Enterprise Linux Server release 4.2 (Tikanga)

3.安装相应包

用Yum安装一下包:

修改/etc/yum.repos.d/rhel-debuginfo.repo为如下格式:

[oracle@scdb admin]$ cat /etc/yum.repos.d/rhel-debuginfo.repo

[Cluster]

name=Red Hat Enterprise

baseurl=file:///software/oracle/temp/Cluster

enabled=1

gpgcheck=0

[ClusterStorage]

name=Red Hat Enterprise  ClusterStorage

baseurl=file:///software/oracle/temp/ClusterStorage

enabled=1

gpgcheck=0

[Server]

name=Red Hat Enterprise  Server

baseurl=file:///software/oracle/temp/Server

enabled=1

gpgcheck=0

[VT]

name=Red Hat Enterprise Linux $releasever - $basearch - VT

baseurl=file:///software/oracle/temp/VT

enabled=1

gpgcheck=0

其中/software/oracle/temp为系统盘对应目录

yum -y install  binutils   compat*    elfutils*    gcc*   glibc*   ksh   libaio*   libstdc*     make    numactl*  sysstat*   libXp*

4.增加oracle用户和组

groupadd -g 501 oinstall

groupadd -g 500 dba

useradd -g oinstall -G dba oracle

passwd oracle

5.修改oracle配置文件

su - oracle

vi .bash_profile 增加以下几行：

[oracle@scdb ~]$ 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

LANG=C; export LANG

ORACLE_BASE=/software/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/10g; export ORACLE_HOME

ORACLE_SID=zsdsdb; export ORACLE_SID

NLS_LANG=AMERICAN_AMERICA.zhs16gbk; export NLS_LANG

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

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

6.使用vncserver来图形界面安装

在root执行

[root@scdb ~]# xhost +

7.安装完毕后需修改listener.ora文件

修改listener.ora为如下：

[oracle@scdb admin]$ cat listener.ora

# listener.ora Network Configuration File: /software/oracle/product/10g/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /software/oracle/product/10g)

(PROGRAM = extproc)

)

(SID_DESC =

(ORACLE_HOME = /software/oracle/product/10g)

(SID_NAME = zsdsdb)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 150.17.20.202)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

)

)

备注：

1. 使用裸设备创建ASM磁盘方法:

1.1 修改裸设备属性:

chown oracle:oinstall /dev/sdf

[root@scdb oracle]# ls -la /dev/sdf

brw-r----- 1 oracle oinstall 8, 81 Jun 30 18:39 /dev/sdf

1.2 在ASM实例里面修改如下属性为你创建裸设备的名称

SQL> alter system set asm_diskstring='/dev/sdf';

System altered.

1.3 在ASM实例里面创建磁盘组:

CREATE DISKGROUP DGZSDS  EXTERNAL REDUNDANCY  DISK '/dev/sdf';

1.4.修改/etc/rc.local里面裸设备的属性,避免重启后属组变化:

[oracle@scdb admin]$ cat /etc/rc.local

#!/bin/sh

#

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here if you don't

# want to do the full Sys V style init stuff.

chown oracle:oinstall /dev/sdf

touch /var/lock/subsys/local
