今天体验了一把Oracle 11gR2的安装，Linux单机+ASM存储，还是有一些变化，记录了安装的过程。

参考：http://www.itpub.net/viewthread.php?tid=1214806&extra=&page=1

从11gR2开始, 如果要安装RAC, ASM, ACFS(11gR2最新支持的ASM集群文件系统), 必须先从安装包Grid Infrastructure下手, 然后才安装Oracle Database.
Oracle Grid Infrastructure includes the following features:
Oracle Clusterware
Application monitoring, restart, and failover
Cluster membership services
Server monitoring and fencing
Single Client Access Name (SCAN)
Server Pools
Grid Naming Services
Oracle Automatic Storage Management
Dynamic storage rebalancing
Storage mirroring
Online disk add/drop
ASM Cluster File System
Shared file system with concurrent access to files from multiple nodes
Local file system
ASM Dynamic Volumes
Volume management services for ACFS
Volume management services for 3rd-party file systems

一.安装准备：

需要安装的rpm包：
make
binutils
gcc
libgomp
libaio
glibc
compat-libstdc++
elfutils-libelf
elfutils-libelf-devel
elfutils-libelf-devel-static
glibc-common
glibc-devel
glibc-headers
kernel-headers
gcc-c++
libaio-devel
libgcc
libstdc++
libstdc++-devel
sysstat
unixODBC
unixODBC-devel
ksh

创建用户和组：
#以下皆使用root用户执行
/usr/sbin/groupadd -g 501 oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 503 oper
/usr/sbin/groupadd -g 504 asmadmin
/usr/sbin/groupadd -g 505 asmoper
/usr/sbin/groupadd -g 506 asmdba
/usr/sbin/useradd -g oinstall -G dba,asmdba,oper oracle
/usr/sbin/useradd -g oinstall -G asmadmin,asmdba,asmoper,oper,dba grid

mkdir -p /u01/app/oracle/product/11.2.0/dbhome_1
mkdir -p /u01/app/grid/product/11.2.0/grid
chown -R oracle:oinstall /u01/app/
chown -R grid:oinstall /u01/app/grid
chmod -R 775 /u01/

# passwd grid
# passwd oracle

修改系统参数：

gird时间同步所需要的设置(11gR2新增检查项)
#Network Time Protocol Setting
/sbin/service ntpd stop
chkconfig ntpd off
rm /etc/ntp.conf
or, mv /etc/ntp.conf to /etc/ntp.conf.org.

修改gird、oracle用户的.bash_profile文件：
#grid 用户配置文件 ORACLE_HOSTNAME请自行设置
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=UMI; export ORACLE_HOSTNAME
ORACLE_SID=+ASM; export ORACLE_SID

        if [ $SHELL = "/bin/ksh" ]; then
              ulimit -p 16384
              ulimit -n 65536
        else
              ulimit -u 16384 -n 65536

二.安装过程：
1.安装配置asmlib，创建好asm磁盘：
内核：
Linux rhel3 2.6.18-164.el5
下载：
oracleasm-2.6.18-164.el5-2.0.5-1.el5.i686.rpm
oracleasmlib-2.0.4-1.el5.i386.rpm
oracleasm-support-2.1.3-1.el5.i386.rpm

安装：
[root@rhel3 asmlib]# rpm -ivh *.rpm
Preparing...                ########################################### [100%]
   1:oracleasm-support      ########################################### [ 33%]
   2:oracleasm-2.6.18-164.el########################################### [ 67%]
   3:oracleasmlib           ########################################### [100%]

配置：
[root@rhel3 asmlib]# /etc/init.d/oracleasm configure
Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver.  The following questions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: grid
Default group to own the driver interface []: asmadmin
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done

磁盘划分分区：
[root@rhel3 proc]# cat partitions
major minor  #blocks  name

   8     0   41943040 sda
   8     1   39841168 sda1
   8     2    2096482 sda2
   8    16   10485760 sdb
[root@rhel3 proc]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

创建ASM磁盘：
[root@rhel3 /]# fdisk -l /dev/sdb

255 heads, 63 sectors/track, 1305 cylinders

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1        1305    10482381    5  Extended
/dev/sdb5               1         250     2008062   83  Linux
[root@rhel3 /]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb5

[root@rhel3 /]# /etc/init.d/oracleasm scandisks

2.用grid用户登录执行grid infrastructure包解压文件中的./runInstaller对grid infrastrucute进行安装配置(Install and Configure Grid Infrastructure for a Standalone Server)(包括了对asm磁盘的初始化配置工作)。
3.用grid用户登录执行netca创建和配置监听器并启动运行。
4.用oracle用户登录执行database解压文件中的./runInstaller安装DBMS。
5.用oracle用户登录执行dbca创建数据库(使用初始化好了的asm磁盘组作为存储)。

三.安装注意事项：
1. 在安装数据库之前需要先将监听器配置、启动成功(grid用户下的netca)。
2. 如果安装grid infrastructure时候是单独进行的安装，那么在使用asmca配置asm之前需要先对grid infrastructure进行相关的配置（配置方法见最后），其他方式不需要。配置完成后执行以下$GRID_HOME/root.sh。然后就可以使用asmca配置了。
 

如果只安装了grid infrastructure软件而没有对其进行配置可以按照下述方法在完成安装后进行配置：
To configure Grid Infrastructure for a Stand-Alone Server run the following command as the root user:
/u01/app/grid/product/11.2/grid/perl/bin/perl -I/u01/app/grid/product/11.2/grid/perl/lib -I/u01/app/grid/product/11.2/grid/crs/install /u01/app/grid/product/11.2/grid/crs/install/roothas.pl

To configure Grid Infrastructure for a Cluster perform. the following steps:
1. Provide values for Grid Infrastructure configuration parameters in the file - /u01/app/grid/product/11.2/grid/crs/install/crsconfig_params. For details on how to do this, see the installation guide.
2. Run the following command as the root user:
 /u01/app/grid/product/11.2/grid/perl/bin/perl -I/u01/app/grid/product/11.2/grid/perl/lib -I/u01/app/grid/product/11.2/grid/crs/install /u01/app/grid/product/11.2/grid/crs/install/rootcrs.pl
To update inventory properties for Grid Infrastructure, perform. the following
steps. If a pre-11.2 home is already configured, execute the following:
11.2_Home/oui/bin/runInstaller -updateNodeList -silent -local CRS=false ORACLE_HOME=pre-11.2_Home
Always execute the following to register the current home:
11.2_Home/oui/bin/runInstaller -updateNodeList -silent -local CRS=true ORACLE_HOME=11.2_Home.
If either home is shared, provide the additional argument -cfs.
