修改etc/sysctl.conf文件,在末尾增加：

net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
修改/etc/security/limits.conf文件,在末尾增加：
oracle soft nproc 2047
oracle hard nproc 16383
oracle soft nofile 1023
oracle hard nofile 65535
为了强制使用刚才我们增加的东西，修改/etc/pam.d/login文件末尾：
session required /lib/security/pam_limits.so
session required pam_limits.so
# sysctl -p
现在将oracle11g的安装包解压到/home/oracle/install/目录下。然后进入目录，设置DISPLAY参数(不设置Oracle装不上，可以一试)，开始安装：
root@hardy:~# cd /home/oracle
root@hardy:/home/oracle# chown -R oracle:dba install
root@hardy:/home/oracle# su - oracle
Your account has expired; please contact your system administrator
su: User account has expired
(Ignored)
oracle@hardy:~$ export DISPLAY=127.0.0.1:0.0
oracle@hardy:~$ pwd
/home/oracle
oracle@hardy:~$ ls -l
total 4
drwxr-xr-x 6 oracle dba 4096 2007-09-18 18:50 install
oracle@hardy:~$ cd install
oracle@hardy:~/install$ ls -l
oracle@hardy:~$./runInstaller -ignoreSysPrereqs -jreLoc /usr/lib/jvm/java-6-sun/jre
在安装第二个界面，将用户组选择为dba,选择"Enterprise Edition",将检查到的所有非“Succeeded”的都打上勾,在创建完数据库后，先不点击OK.
进行如下操作：
root@hardy:~# /u01/app/oraInventory/orainstRoot.sh
Changing permissions of /u01/app/oraInventory to 770.
Changing groupname of /u01/app/oraInventory to dba.

然后，在/etc/profile文件中加入下面几句：
export ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1
export PATH=$PATH:/u01/app/oracle/product/11.1.0/db_1/bin
创建一个Oracle 11g数据库的启动脚本，名字可以叫做：oracledb，在/u01/app/oracle/product/11.1.0/db_1/bin下建立文件：oracledb，内容：
#!/bin/bash
#
# /etc/init.d/oracledb
#
# Run-level Startup script for the Oracle Listener and Instances
# It relies on the information on /etc/oratab
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.1.0/db_1
export ORACLE_OWNR=oracle
export PATH=$PATH:$ORACLE_HOME/bin
if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
then
echo "Oracle startup: cannot start"
exit 1
fi
case "$1" in
start)
# Oracle listener and instance startup
echo -n "Starting Oracle: "
su $ORACLE_OWNR -c "$ORACLE_HOME/bin/lsnrctl start"

touch /var/lock/oracle
echo "OK"

stop)
# Oracle listener and instance shutdown
echo -n "Shutdown Oracle: "

echo "OK"
;;
reload|restart)
$0 stop
$0 start
;;
*)
echo "Usage: `basename $0` start|stop|restart|reload"
exit 1
esac
exit 0
修改脚本为可执行的：
root@hardy:~# chmod a+x /u01/app/oracle/product/11.1.0/db_1/bin/oracledb
如果你希望开机自动启动Oracle 11g数据库，那么就作下面的工作：
root@hardy:~# ln -s /u01/app/oracle/product/11.1.0/db_1/bin/oracledb /etc/init.d/oracledb
root@hardy:~# sudo sysv-rc-conf --level 2345 oracledb on
如果没有sysv-rc-conf命令，就apt-get一个。
最后，增加你自己的用户名到dba组：
root@hardy:~# usermod -G dba -a user(注意user为你当前使用的用户，每个人的都不一定相同。)
好了，至此，Oracle 11g就安装完了。重新登录后，你就可以使用oracle的命令了。
你可以通过netca增加LISTENER，通过dbca增加数据库。测试一下是否安装成功：
(ORACLE_SID=heron 是你安装时候设置的值)
oracle@hardy:~$ export ORACLE_SID=orcl
oracle@hardy:~$ sqlplus \'/as sysdba\'
