RedHat Linux AS 4.0上安装Oracle 10g Release 2
3、 设置系统参数 修改#vi /etc/sysctl.conf添加下面代码: kernel.shmall = 2097152 kernel.shmmax = 2147483648 (一般情况下可以设置最大共享内存为物理内存的一半,如果物理内存是 2G,则可以设置最大共享内存为 1073741824(1G=1024*1024*1024)) kern
3、 设置系统参数
修改#vi /etc/sysctl.conf添加下面代码:
kernel.shmall = 2097152
kernel.shmmax = 2147483648
(一般情况下可以设置最大共享内存为物理内存的一半,如果物理内存是 2G,则可以设置最大共享内存为 1073741824(1G=1024*1024*1024))
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
修改后运行#sysctl –p命令使得内核改变立即生效
4、设置oracle用户对Shell的限制要求:
a) 编辑文件:#vi /etc/security/limits.conf 加入以下语句:
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
b) 编辑文件:#vi /etc/pam.d/login 加入以下语句:
session required /lib/security/pam_limits.so
c) 编辑文件:#vi /etc/profile 加入以下语句:
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
5、配置oracle用户环境
使用Oracle用户登陆:
#su – oracle
$vi .bash_profile
以下是配置文件的内容
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
umask 022
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
export ORACLE_BASE=/opt/ora10
export ORACLE_HOME=/opt/ora10/product/10.2.0.1
export PATH=$ORACLE_HOME/Apache/perl/bin:$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin:$PATH
export ORACLE_OWNER=oracle
export ORACLE_SID=oradb
export ORACLE_TERM=xterm
unset USERNAME
三、 安装过程
1、重新启动服务器以oracle用户登录,启动X-window进行本地直接安装。
#su – oracle
$ startx
(我是从Xwindow下启动的,所以掠过此步,但在root下#xhost +)
将Oracle10g光盘文件拷贝到前面建立的安装文件夹(/tmp/oracle)下。(如果是下载,将10201_database_linux_x86_64.cpio.gz拷贝到/tmp/oracle下,
1. Unzip the file: gunzip
2. Extract the file: cpio -idmv
到当前目录)
2、正式安装
1) 点击“任务栏” → “应用程序” → “系统工具” → “终端”:
$ /tmp/oracle/runInstaller (CD到/tmp/oracle/ $./runInstaller)
非常值得称道的是,10g的安装相比以前9i多了一个 Checking operating system certification 的步骤。特别实用。安装文件会自动检测所需的条件。如果有不符合的地方,安装程序会报告给你.并会给出具体原因。
2) 经过一小段的时间,会出现“选择安装方法”的信息窗口;点选“高级安装(A)”,继续安装请单击“下一步(N)”按键;进入“指定产品清单目录和身份证 明”窗口:确认产品清单目录的完整路径(D):/oracle/oraInventory;指定操作系统组名(S):oinstall;继续安装请单击 “下一步(N)”按键;进入“选择安装类型”窗口,点选“企业版(E)”,继续安装请单击“下一步(N)”按键;进入“指定主目录详细信息”窗口;名称 (M):OraDb10g_home1 路径(A): /opt/oracle/product/10.2.0.1/;继续安装请单击“下一步(N)”按键;
3) 进入“产品特定的先决条件检查”窗口,经过一小段时间检查,会出现以下的检查信息窗口;在“正在检查网络配置需要”项目内,选中状态栏目的内容,继续安装 请单击“下一步(N)”按键;进入“选择配置选项”窗口,点选“创建数据库(C)” ,继续安装请单击“下一步(N)”按键;进入“选择数据库配置”窗口,点选“一般用途(G)” ,继续安装请单击“下一步(N)”按键;进入“指定数据库配置选项”窗口;数据库命名中的设置;全局数据库名: oradb SID: oradb;数据库字符集:简体中文ZHS16GBK ;继续安装请单击“下一步(N)”按键;
4) 进入“选择数据库管理选项”窗口,点选“使用Database Control管理数据库”,继续安装请单击“下一步(N)”按键;进入“指定数据库存储选项”窗口,点选“文件系统”;指定数据库文件位置: /oracle/product/10.2.0/oradata/;继续安装请单击“下一步(N)”按键;进入“指定备份和恢复选项”窗口,点选“不启用 自动备份”,继续安装请单击“下一步(N)”按键;进入“指定数据库方案的口令”窗口;点选“所有的帐户都使用同一个口令”,输入口令。继续安装请单击 “下一步(N)”按键;进入“概要信息”窗口,继续安装请单击“下一步(N)”按键;进入“安装”窗口,详细安装如下:A、安装部分片;B、复制文件部 分;C、连接数据系统部分;D、设置数据系统部分;
5) 进入“配置助手”窗口:配置:Oracle Database Configuration Assistant时,会出现“Database Configuration Assistant”新窗口,详细配置过程:A、正在复制数据库文件;B、正在创建并启动Oracle实例;C、正在进行数据库创建;完成以上三个部分, 会出现一个数据库创建完成信息提示窗口,点击“确定”按键。
6) 配置:iSQL*Plus配置辅助程序。配置过程中,会出现一个执行配置脚本信息提示窗口,在终端下运行,执行orainstRoot.sh脚本的过程:点击“任务栏” → “应用程序” → “系统工具” → “终端”,
$ su root (转换成root超级用户环境) Password: ****** (输入root用户的密码)
# /opt/oracle/oraInventory/orainstRoot.sh (输入执行脚本的详细路径)
详细操作:
# /opt/oracle/oracle/product/10.2.0.1/root.sh (输入执行脚本的详细路径)
执行完成orainstRoot.sh、root.sh脚本后,关闭“超级用户的终端”,回到“执行配置脚本”提示窗口,继续安装请单击“确定”按键;进入“安装结束”窗口,退出安装程序请单击“退出(X)”按键;
四、 自启动设置
Oracle 10g需要启动以下服务(在oracle用户下)
$ lsnrctl start
$ dbstart
$ emctl start dbconsole
$ isqlplusctl start
所以需要做以下配置:
默认dbstart是不起作用的。需要以下配置
1.修改/etc/oratab
$ vi /etc/oratab
oradb:/opt/ora10/product/10.2.0.1:Y(原来是N改为Y)
2.拷贝一个系统配置好的 PFILE 到 dbs 目录下
# cp /opt/ora10/admin/oradb/pfile/init.ora.2292007201045 $ORACLE_HOME/dbs/init.ora ($ORACLE_HOME路径要看安装路径而定)
现在你可以测试一下
$ dbstart
注:如果安装版本是10201,可能会出现这个错误:
Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr
修改dbstart的第78行 ($ORACLE_HOME/bin/dbstart)
ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle
为ORACLE_HOME_LISTNER=$ORACLE_HOME
$ dbshut
最后在/etc/rc.d/rc.local中加入如下代码:
su - oracle -c "lsnrctl start"
su - oracle -c "dbstart"
su - oracle -c "emctl start dbconsole"
su - oracle -c "isqlplusctl start"
这样重启动服务器后Oracle就会自动启动了。
五、 Oracle 10g设置
iSQL*Plus URL:连接地址:http://server:5560/isqlplus
iSQL*Plus DBA URL:连接地址:http://server:5560/isqlplus/dba
Enterprise Manager 10g Database Control URL:连接地址:http://server:1158/em
用户名:sys
口令:******
连接身份:SYSDBA
继续登陆请单击 “我同意”按键;
#su – oracle
$ startx
$netca启动配置网络配置助手
$sqlplus /nolog启动sqlplus
$dbca 启动数据库配置助手(DCA),建oracle数据库
