racle ASMLib driver: [ ?OK ?]
Scanning the system for Oracle ASMLib disks: [ ?OK ?]
?
2、启用ASMLib驱动程序：
[root@wwl asmpark]# /etc/init.d/oracleasm enable
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ ?OK ?]
Scanning the system for Oracle ASMLib disks: [ ?OK ?]
?
3、通过以root用户身份运行以下命令来标记由 ASMLib 使用的磁盘：
?
[root@wwl asmpark]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb1
Marking disk "VOL1" as an ASM disk: [ ?OK ?]
[root@wwl asmpark]# /etc/init.d/oracleasm createdisk VOL2 /dev/sdc1
Marking disk "VOL2" as an ASM disk: [ ?OK ?]
[root@wwl asmpark]#
?
4、通过如下命令查看ASM所能使用的磁盘及状态，一切显示都是正常的。
[root@wwl asmpark]# oracleasm querydisk VOL1
Disk "VOL1" is a valid ASM disk
[root@wwl asmpark]# oracleasm querydisk /dev/sdb1
Device "/dev/sdb1" is marked an ASM disk with the label "VOL1"
[root@wwl asmpark]# oracleasm querydisk VOL2
Disk "VOL2" is a valid ASM disk
[root@wwl ~]# oracleasm querydisk /dev/sdc1
Device "/dev/sdc1" is marked an ASM disk with the label "VOL2"
[root@wwl asmpark]# oracleasm listdisks
VOL1
VOL2
[root@wwl asmpark]# ls -l /dev/oracleasm/disks/*
brw-rw---- 1 oracle dba 8, 17 Apr 10 00:25 /dev/oracleasm/disks/VOL1
brw-rw---- 1 oracle dba 8, 33 Apr 10 00:25 /dev/oracleasm/disks/VOL2
[root@wwl asmpark]# oracleasm status
Checking if ASM is loaded: yes
Checking if /dev/oracleasm is mounted: yes
?
5、如上ASMLib已经安装完成，并且也将磁盘标记为可用，接下来要做的就是创建ASM实例，并构建一个使用ASM磁盘来存储数据的
数据库，可以使用DBCA，当然也可以使用手工的方式来创，在这里，我就采用手工方式创建ASM实例，步骤如下：
?
6、创建初始化参数文件,信息如下：
[oracle@ jb51.net dbs]$ vi $ORACLE_HOME/dbs/init$ORACLE_SID.ora
asm_diskstring='WWL:VOL*'
background_dump_dest='/oracle/admin/+ASM/bdump'
core_dump_dest='/oracle/admin/+ASM/cdump'
user_dump_dest='/oracle/admin/+ASM/udump'
instance_type='asm'
large_pool_size=12M
remote_login_passwordfile='SHARED'
?
7、增加实例信息到/etc/oratab
$ vi /etc/oratab
+ASM:/u01/app/oracle/product/10.2.0/db_1:Y
?
8、创建ASM实例密码文件：
[oracle@ jb51.net dbs]$ $ORACLE_HOME/bin/orapwd file=$ORACLE_HOME/dbs/orapw$ORACLE_SID password='oracle' force=y;
[oracle@ jb51.net dbs]$
?
9、创建ASM实例相应的目录:
[oracle@ jb51.net dbs]$ ?mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/bdump
[oracle@ jb51.net dbs]$ mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/cdump
[oracle@ jb51.net dbs]$ mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/udump
[oracle@ jb51.net dbs]$
?
$ su - root
[root@wwl ~]# /oracle/orahome/10.2.0/db_1/bin/localconfig add
/etc/oracle does not exist. Creating it now.

? ? ? ? wwl

?
11、启动ASM实例，并创建ASM磁盘组：
[oracle@ jb51.net dbs]$ sqlplus / as sysdba
