一、准备安装
  基本都是按部就班。
  使用的OS版本:OEL4
  [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
  创建用户
  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
  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:
  kernel.shmall = 2097152
  kernel.shmmax = 2 147483648
  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:
  代码:
  [oracle@ractest ~]$ xclock
  [oracle@ractest ~]$ /mnt/Oracle11g_linux_x86_64/database
  [oracle@ractest ~]$ cd /mnt/Oracle11g_linux_x86_64/database
  [oracle@ractest database]$ ls -l
  total 10
  drwxr-xr-x 4 1003 oinstall 96 Mar 23 18:45 doc
  drwxr-xr-x 5 1003 oinstall 1024 Mar 23 18:45 install

  [oracle@ractest database]$ ./runInstaller

  启动图形以后选择basic&n
  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
  执行提示脚本,安装完毕
  代码:
  [oracle@ractest database]$
  [oracle@ractest database]$ su – root
  Password:
  [root@ractest ~]# /home/oracle/oraInventory/orainstRoot .sh
