Oracle11g安装步骤详解

Oracle11g从去年年底发布至今已经有一段时间了，我可以说也算首批体验Oracle11g的客户了吧，也许是对Oracle11g的太期待，所以他还没发布我就了解了好多好多Oracle11g的新特性和很多关于它的新技术，现对Oracle11g的安装作一下介绍，希望能对初学者或了解不深的客户有所帮助.
我使用的OS版本是：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
　　创建用户

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 　　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 [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 drwxr-xr-x 2 1003 oinstall 1024 Mar 23 18:45 response -rwxr-xr-x 1 1003 oinstall 1251 Mar 23 18:45 runInstaller drwxr-xr-x 12 1003 oinstall 1024 Mar 23 18:45 stage -rw-r--r-- 1 1003 oinstall 4638 Mar 23 18:45 welcome.html [oracle@ractest database]$ ./runInstaller Starting Oracle Universal Installer...

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

以下是引用片段： [oracle@ractest database]$ [oracle@ractest database]$ su - root Password: [root@ractest ~]# /home/oracle/oraInventory/orainstRoot.sh Changing permissions of /home/oracle/oraInventory to 770. Changing groupname of /home/oracle/oraInventory to dba. The execution of the script is complete [root@ractest ~]# /home/oracle/11g/root.sh Running Oracle11g root.sh script... The following environment variables are set as: ORACLE_OWNER= oracle ORACLE_HOME= /home/oracle/11g Enter the full pathname of the local bin directory: [/usr/local/bin]: Copying dbhome to /usr/local/bin ...

通过这个例子你可以十分清楚的了解Oracle11g的安装过程，诸多惊喜尽在Oracle11g，赶快加入我们的Oracle11g应用行列吧。
