Configure ASM on Oracle 11.2.0.3

   ASM存储的作用和好处以及劣势，在这里就不多做介绍了，google下相关的资料多如牛毛！本文主要记录如何在oracle 11.2.0.3版本上面使用ASM存储！相关的软件包可以在http://support.oracle.com网站上下载到，11.2.0.3的补丁集只需要下载前3个即可，在10g中，ASM是包含在数据库软件包当中的，在11g里面，需要单独安装grid infrastructure才可以使用ASM，一般推荐的做法是新建一个grid用户来管理ASM实例！在开始之前要先安装好必须得软件包，调整好内核参数，以及grid，oracle用户的最大进程数和文件句柄打开数等等，这方面的配置可以参考oracle 11g的online document
 
一：创建用户和相关目录，设置用户的环境变量和目录权限

[root@dg63 ~]# groupadd -g 501 oinstall [root@dg63 ~]# groupadd -g 502 dba [root@dg63 ~]# groupadd  -g 503 oper [root@dg63 ~]# groupadd  -g 504 asmadmin [root@dg63 ~]# groupadd  -g 506 asmdba [root@dg63 ~]# groupadd  -g 507 asmoper [root@dg63 ~]# useradd -u 501 -g oinstall -G asmadmin,asmdba,asmoper grid [root@dg63 ~]# useradd -u 502 -g oinstall -G dba,asmdba,oper oracle [root@dg63 ~]# mkdir -p /u01/app/11.2.0/grid [root@dg63 ~]# mkdir -p /u01/app/oracle/product/11.2.0/db_1 [root@dg63 ~]# mkdir -p /u01/app/grid [root@dg63 ~]# mkdir -p /u01/app/oraInventory [root@dg63 ~]# chown -R oracle.oinstall /u01 [root@dg63 ~]# chown -R grid.oinstall /u01/app/11.2.0/grid/ [root@dg63 ~]# chown -R grid.oinstall /u01/app/grid/ [root@dg63 ~]# chown -R grid.oinstall /u01/app/oraInventory/ [root@dg63 ~]#  echo oracle |passwd --stdin oracle Changing password for user oracle. passwd: all authentication tokens updated successfully. [root@dg63 ~]#  echo oracle |passwd --stdin grid Changing password for user grid. passwd: all authentication tokens updated successfully. [root@dg63 ~]# id oracle uid=502(oracle) gid=501(oinstall) groups=501(oinstall),502(dba),503(oper),506(asmdba) [root@dg63 ~]# id grid uid=501(grid) gid=501(oinstall) groups=501(oinstall),504(asmadmin),506(asmdba),507(asmoper) [root@dg63 ~]# cat /home/grid/.bash_profile # .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 export ORACLE_SID=+ASM export ORACLE_BASE=/u01/app/grid export ORACLE_HOME=/u01/app/11.2.0/grid export ORACLE_TERM=xterm export NLS_DATE_FORMAT="DD-MON-YYYY HH24:MI:SS" export TNS_ADMIN=$ORACLE_HOME/network/admi export PATH=.:/usr/sbin:$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/X11R6/lib:$LD_LIBRARY_PATH export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$CLASSPATH export NLS_LANG="american_america.AL32UTF8" export EDITOD=vim export LANG=en_us.UTF-8 export NLS_DATE_FORMAT=yyyy-mm-dd:hh24:mi:ss export TEMP=/tmp export TMPDIR=/tmp umask 022 alias sqlplus='/usr/local/rlwrap/bin/rlwrap sqlplus' alias rman='/usr/local/rlwrap/bin/rlwrap rman' [root@dg63 ~]# cat /home/oracle/.bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then         . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export PATH export ORACLE_SID=dg63 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export ORACLE_TERM=xterm export NLS_DATE_FORMAT="DD-MON-YYYY HH24:MI:SS" export TNS_ADMIN=$ORACLE_HOME/network/admi export PATH=.:/usr/sbin:$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/X11R6/lib:$LD_LIBRARY_PATH export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$CLASSPATH export NLS_LANG="american_america.AL32UTF8" export EDITOD=vim export LANG=en_us.UTF-8 export NLS_DATE_FORMAT=yyyy-mm-dd:hh24:mi:ss export TEMP=/tmp export TMPDIR=/tmp umask 022 alias sqlplus='/usr/local/rlwrap/bin/rlwrap sqlplus' alias rman='/usr/local/rlwrap/bin/rlwrap rman'

 二：创建ASM实例和磁盘组,需要安装oracle提供的asmlib包，然后配置下asm的用户和组，接着创建磁盘如下

[root@dg63 ~]# oracleasm listdisks DATA FRA [root@dg63 ~]# su - grid [grid@dg63 ~]$ cd /u01/11.2.0.3/grid/ [grid@dg63 grid]$ ./runInstaller

 

 

  

 

 

 

 

 

 

 

 [grid@dg63 ~]$ asmca

 

 

 

[root@dg63 ~]# ps -ef |grep ASM

三：使用oracle用户dbca建库，并验证！
