一、准备安装
基本都是按部就班。
使用的OS版本：OEL4
以下是引用片段：
[oracle@ractest orcl]$ cat /etc/redhat-release
Enterprise Linux Enterprise Linux AS release 4 (October Update 5)
[oracle@ractest orcl]$ cat /etc/enterprise-release
Enterprise Linux Enterprise Linux AS release 4 (October Update 5)
安装程序路径：
/mnt/Oracle11g_linux_x86_64/database
以下是引用片段：
groupadd -g 1001 dba
groupadd -g 1002 oinstall
useradd -u 10000 -g dba -G oinstall,dba -d /home/oracle -s /bin/bash oracle
chown -R oracle:dba /home/oracle
usermod -g dba -G oinstall,dba oracle
使用的.bash_profile
export ORACLE_BASE=/home/oracle
export ORACLE_HOME=$ORACLE_BASE/11g
export ORA_CRS_HOME=$ORACLE_BASE/crs
export ORACLE_PATH=$ORACLE_BASE/common/oracle/sql:.:$ORACLE_HOME/rdbms/admin
export ORACLE_SID=orcl1 bbs.bitsCN.com
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:${PATH}:$HOME/bin
export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin
export PATH=${PATH}:$ORACLE_BASE/common/oracle/bin
export ORACLE_TERM=xterm
export TNS_ADMIN=$ORACLE_HOME/network/admin
export ORA_NLS10=$ORACLE_HOME/nls/data
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/lib:/usr/lib:/usr/local/lib:$ORACLE_HOME/oracm/lib:$ORACLE_HOME/lib
export LIBPATH=$LIBPATH:$ORA_CRS_HOME/lib:$ORACLE_HOME/lib
export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/jlib:$ORACLE_HOME/network/jlib:$ORACLE_HOME/JRE
export THREADS_FLAG=native
export TEMP=/tmp
export TMPDIR=/tmp
export NLS_LANG=american_america.WE8ISO8859P1
export DISPLAY=10.198.90.55:2
alias sysdba="sqlplus '/as sysdba'"
export EDITOR=vi
修改的核心参数：
以下是引用片段：
kernel.shmall = 2097152
kernel.shmmax = 2147483648
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.wmem_default=262144
net.core.rmem_max=262144
net.core.wmem_max=262144
使用xclock检查display正确：
以下是引用片段：
[oracle@ractest ~]$ xclock
[oracle@ractest ~]$ /mnt/Oracle11g_linux_x86_64/database
[oracle@ractest ~]$ cd /mnt/Oracle11g_linux_x86_64/database bitsCN~com
[oracle@ractest database]$ ls -l

启动图形以后选择ba
选择oracle base的时候，oracle不推荐使用user home作为oracle base，这里我选yes忽略
进行prerequirements检查的时候，安装程序认为swap不足，我选择YES忽略
