Oracle安装笔记
只修改时间,输入:date -s 14:15:00
同时修改日期时间,注意要加双引号,日期与时间之间有一空格,输入:date -s "2015-08-03 14:15:00"
修改完后,记得输入:clock -w
root用户登录
1，交换区检查：
grep MemTotal /proc/meminfo
grep SwapTotal /proc/meminfo
2，磁盘空间情况
[root@localhost app]# df -h
注意，如果切换用户su - oracle时出现-bash-3.2$的提示符是因为把oracle用户的.bash_profile最前面的if语句注释掉的问题，放开就好了。
系统参数修改
1，修改内核
增加到/etc/sysctl.conf中
# For Oracle Install
fs.file-max = 6553600
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144
配置生效：
[root@localhost ~]# sysctl -p
2，修改用户资源限制
/etc/security/limits.conf
#Oracle Install Add
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
3，登录限制
/etc/pam.d/login
session required /lib/security/pam_limits.so
4，
Vim /etc/profile
if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
安装包
1，安装包检查
rpm -q gcc make binutils openmotif setarch compat-db compat-gcc \
> compat-gcc-c++ compat-libstdc++ compat-libstdc++-devel
2，安装

增加用户名
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/useradd -m -g oinstall -G dba oracle
id oracle
passwd oracle
修改变量
修改.bash_profile文件：此文件隐藏，在/home/oracle/.base_profile
增加以下内容：
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
# For Oracle Install
export ORACLE_BASE=/home/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10g
export PATH=$PATH:$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin
export ORACLE_OWNER=oracle
export ORACLE_SID=mmkt11
export NLS_LANG=" american_america.WE8ISO8859P1 "
修改完毕，执行如下操作，使设置生效：
[root@localhost ~]# source /home/oracle/.bash_profile
安装数据库
1,新建目录
[root@localhost /]# mkdir -p /u01
2,赋给数据库安装目录权限
[root@localhost /]# chown -R oracle:oinstall /u01
3,切换Oracle进入图形化界面进入安装目录运行
./instsllrun
创建数据库及配置
1,用oracle用户，进入Oracle软件目录下的bin目录，运行dbca
2,用oracle用户，进入Oracle软件目录下的bin目录，运行netca
