如何在redhat 9,redhat ELAS 3/2.1,redat FC1 上安装oracle 10g(2)

#cat > /etc/redhat-release << EOF

#Red Hat EnterpriseLinuxAS release 3 (Taroon)

#EOF

记得安装完Oracle10g要还原该文件内容:

$su - root

#cp /etc/redhat-release.backup /etc/redhat-release

好了,做完以上的準备工作,我们该开始令人激动的Oracel10g安装! 安装前我们还需设定一下与Oracle相关的内核参数

先看看所有内核参数:

$su - root

#sysctl -a

安装执行指令在/tmp/Disk1下,我们不建议直接执行
runInstaller -ignoreSysPrereqs


对於Oracle10g, 需要设定为以下参数值,可以设定更大一点的值:

查核结果可执行右边括号中内容

shmmax  = 2147483648     (cat /proc/sys/kernel/shmmax)

这意味着系统的共享内存达到4G，这是不合适的。一般，SHMMAX的设置可略大于本机内存配置。
事实上，缺省安装的RedHat 6.0核心运行Oracle 8.0.5是没有问题的，一般情况下可不对这些参数作出调整。
如确需调整，在完成修改后，要按文档要求重生成核心，并用lilo命令指定用新的核心进行引导。

shmmni  = 4096           (cat /proc/sys/kernel/shmmni)

shmall  = 2097152        (cat /proc/sys/kernel/shmall)

shmmin  = 1              (ipcs -lm |grep "min seg size")

shmseg  = 10             (被硬编码在kernel中,缺省值更高)

semmsl  = 250            (cat /proc/sys/kernel/sem | awk '{print $1}')

semmns  = 32000          (cat /proc/sys/kernel/sem | awk '{print $2}')

semopm  = 100            (cat /proc/sys/kernel/sem | awk '{print $3}')

semmni  = 128            (cat /proc/sys/kernel/sem | awk '{print $4}')

file-max = 65536         (cat /proc/sys/fs/file-max)

ip_local_port_range = 1024 65000

                         (cat /proc/sys/net/ipv4/ip_local_port_range)

 

NOTE: Do not change the value of any kernel parameter on a system where it is already higher than listed as minimum requirement.

On RHELAS3, RHELAS2.1, RH9, and on FC1 I had to increase the kernel parameters shmmax, semopm, and filemax to meet the minimum requirement.

Oracle also recommends to set the local port range ip_local_port_range for outgoing messages to "1024 65000" which is needed for high-usage systems. This kernel parameter defines the local port range for TCP and UDP traffic to choose from.

I added the following lines to the /etc/sysctl.conf file which is used during the boot process:

kernel.shmmax=2147483648

kernel.sem=250 32000 100 128

fs.file-max=65536

net.ipv4.ip_local_port_range=1024 65000

Adding these lines to the /etc/sysctl.conf file will cause the system to change these kernel parameters after each boot using the /etc/rc.d/rc.sysinit script. which is invoked by /etc/inittab. But in order that these new added lines or settings in /etc/sysctl.conf become effective immediately, execute the following command:

su - root

sysctl -p

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

<在/oracle/10.1.0/bin/dbshut 加入>

##自动关闭Listner

if [ -f $ORACLE_HOME/bin/lsnrctl ] ; then

  $ORACLE_HOME/bin/lsnrctl stop

fi

##自动关闭OracleApache Jserv

if [ -f $ORACLE_HOME/Apache/Apache/bin/httpdsctl ] ; then

  $ORACLE_HOME/Apache/Apache/bin/httpdsctl stop

fi


36.完成後请测试

        $/oracle/10.1.0/bin/dbstart

        $/oracle/10.1.0/bin/dbshut

37.开机自动启动 Oracle

    请将oracle10g这个script. cp至/etc/rc.d/init.d

        $cp oracle10g /etc/rc.d/init.d

    再加入开机服务程序中

    #chkconfig --add oracle10g

    #linuxconf

   用linuxconf即可控制启动的层次.
