oracle从普通文件系统迁移到ASM

一、准备工作
    1.计算目前数据文件大小

SYS>select sum(BYTES)/1024/1024/1024 || 'G' as GB  from v$datafile;

GB
-----------------------------------------
90.8349609375G

    2.关闭服务器添加6块硬盘

[root@ora01 rules.d]# cat  60-raw.rules
ACTION=="add", KERNEL=="sdb", RUN+="/bin/raw /dev/raw/raw1 %N"
ACTION=="add", KERNEL=="sdc", RUN+="/bin/raw /dev/raw/raw2 %N"
ACTION=="add", KERNEL=="sdd", RUN+="/bin/raw /dev/raw/raw3 %N"
ACTION=="add", KERNEL=="sde", RUN+="/bin/raw /dev/raw/raw4 %N"
ACTION=="add", KERNEL=="sdf", RUN+="/bin/raw /dev/raw/raw5 %N"
ACTION=="add", KERNEL=="sdg", RUN+="/bin/raw /dev/raw/raw6 %N"
KERNEL=="raw[0-9]*",OWNER="oracle",GROUP="oinstall",MODE="640"

    3.install asm rpms
   

[root@ora01 asmrpm]# rpm -Uvh  oracleasm-support-2.1.2-1.el5.i386.rpmPreparing...                ########################################### [100%]   1:oracleasm-support      ########################################### [100%][root@ora01 asmrpm]# rpm -Uvh  oracleasm-2.6.18-128.el5PAE-2.0.5-1.el5.i686.rpmwarning: oracleasm-2.6.18-128.el5PAE-2.0.5-1.el5.i686.rpm: Header V3 DSA signature: NOKEY, key ID 1e5e0159Preparing...                ########################################### [100%]   1:oracleasm-2.6.18-128.el########################################### [100%][root@ora01 asmrpm]# rpm -Uvh oracleasmlib-2.0.3-1.el5.i386.rpmPreparing...                ########################################### [100%]   1:oracleasmlib           ########################################### [100%]

    4.Configuring the Oracle ASM library driver

[root@ora01 asmrpm]# /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 [oinstall]:
Start Oracle ASM library driver on boot (y/n) [y]:
Scan for Oracle ASM disks on boot (y/n) [y]:
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver:                     [  OK  ]
Scanning the system for Oracle ASMLib disks:               [  OK  ]
