注意，請順序安裝，如果中間卻少相關係統包，請找到相關包進行安裝；
rpm -vhi oracleasm-support-2.1.7-1.el5.i386.rpm
rpm -ivh oracleasm-2.6.18-194.el5-2.0.5-1.el5.i686.rpm
rpm -vhi oracleasmlib-2.0.4-1.el5.i386.rpm
rpm -vhi oracleasm-2.6.18-194.el5debug-2.0.5-1.el5.i686.rpm
rpm -vhi oracleasm-2.6.18-194.el5-debuginfo-2.0.5-1.el5.i686.rpm
rpm -vhi oracleasm-2.6.18-194.el5PAE-2.0.5-1.el5.i686.rpm
rpm -vhi oracleasm-2.6.18-194.el5xen-2.0.5-1.el5.i686.rpm
在我們的實驗裏，我需要如下系統包：
kernel-debug-2.6.18-194.el5.i686.rpm
kernel-PAE-2.6.18-194.el5.i686.rpm
kernel-xen-2.6.18-194.el5.i686.rpm
1.2. 配置oracleasm(root身份)
[root@dbserver2 oracle]# /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 <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
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
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks:
[ OK ]

1.3. 準備磁盤設備
1.3.1. 給虛擬機增加硬盤
一路點 next 直到創建盤成功；
1.3.2. 進入操作系統 fdisk 格式化硬盤(root身份)
[root@dbserver2 oracle]# fdisk -l
Disk /dev/sda: 21.4 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table
[root@dbserver2 oracle]#
[root@dbserver2 oracle]# 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 1044.
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)

1.4. 創建asm磁盤卷設備(root身份)
[root@localhost oracle]#
[root@localhost oracle]# /etc/init.d/oracleasm createdisk vol1 /dev/sdb1
Marking disk "vol1" as an ASM disk: [ OK ]
[root@localhost oracle]# /etc/init.d/oracleasm createdisk vol2 /dev/sdb2
Marking disk "vol2" as an ASM disk: [ OK ]
[root@localhost oracle]#
[root@localhost oracle]# /etc/init.d/oracleasm listdisks
VOL1
VOL2
1.4.1. 異常錯誤處理
如果出出現錯誤：Marking disk "VOL1" as an ASM disk: [FAILED]
查看日誌
[root@Oracle11gOcp_catalog disks]# less /var/log/oracleasm
1.如果是如下錯誤信息：
Disk "VOL1" does not exist or is not instantiated
Writing disk header: done
Instantiating disk: oracleasm-instantiate-disk: Unable to open manager: No such file or directory
failed
Clearing disk header: done
此表示沒有啓用 oracleasm 需要執行：
[root@Oracle11gOcp_catalog ~]# /etc/init.d/oracleasm enable
2.如果是如下錯誤信息：
Device "/dev/sdc1" is already labeled for ASM disk "VOL1"
解決的兩種方法：
1). 刪除已存在的asm盤
/etc/init.d/oracleasm deletedisk VOL1
2). 更名增加asm盤
/etc/init.d/oracleasm createdisk volX /dev/sdb1
1.5. 準備grid安裝軟件
[oracle@dbserver2 ~]$ cd /oracle_soft/
[oracle@dbserver2 oracle_soft]$ ls
database p10404530_112030_LINUX_3of7.zip
[oracle@dbserver2 oracle_soft]$ unzip p10404530_112030_LINUX_3of7.zip
[oracle@dbserver2 oracle_soft]$ ls
database grid p10404530_112030_LINUX_3of7.zip
[oracle@dbserver2 oracle_soft]$
[oracle@dbserver2 oracle_soft]$
[oracle@dbserver2 oracle_soft]$ rm -rf p10404530_112030_LINUX_3of7.zip
[oracle@dbserver2 oracle_soft]$
[oracle@dbserver2 oracle_soft]$ ls

1.6. 創建數據庫

有個奇怪現象，我沒有配置系統啓動asm實例與oracle實例，怎麼一啓操作系統就隨系統啓動了...
