5. install Oracle
不要安装实例

6. create asm.ora
创建初始化文件
 
#touch $ORACLE_HOME/dbs/init+ASM.ora

*.asm_diskstring='/dev/oracleasm/disks/VOL*'

*.asm_diskgroups='dgroup1'

*.background_dump_dest='/u01/admin/+ASM/bdump'

*.remote_login_passwordfile='SHARED'

*.user_dump_dest='/u01/admin/+ASM/udump'
[root@localhost~]# export ORACLE_SID=+ASM

创建密码文件

[oracle]$ orapwd file=orapwd+ASM password=dba
创建目录结构
