手动创建Oracle 10g ASM磁盘组

手动创建Oracle 10g ASM磁盘组

准备环境：

Oracle 10g 联机文档、已经配置10g数据库软件的主机、oracleasm library rpm包、2块5GB硬盘

1、  查看本机磁盘信息

[root@shiyueasm~]# fdisk -l

 

Disk/dev/sda: 16.1 GB, 16106127360 bytes

255 heads,63 sectors/track, 1958 cylinders

Units =cylinders of 16065 * 512 = 8225280 bytes

 

   Device Boot      Start         End      Blocks  Id  System

/dev/sda1   *        307        1958    13269690  83  Linux

/dev/sda2               1         306    2457913+  82 Linux swap

 

Partitiontable entries are not in disk order

 

Disk/dev/sdb: 10.7 GB, 10737418240 bytes

255heads, 63 sectors/track, 1305 cylinders

Units =cylinders of 16065 * 512 = 8225280 bytes

 

   Device Boot      Start         End      Blocks  Id  System

/dev/sdb1   *          1        1305    10482381  83  Linux

 

Disk/dev/sdc: 5368 MB, 5368709120 bytes

255heads, 63 sectors/track, 652 cylinders

Units =cylinders of 16065 * 512 = 8225280 bytes

 

Disk/dev/sdc doesn't contain a valid partition table

 

Disk/dev/sdd: 5368 MB, 5368709120 bytes

255heads, 63 sectors/track, 652 cylinders

Units =cylinders of 16065 * 512 = 8225280 bytes

 

Disk /dev/sdd doesn't contain a validpartition table

2、  对新添加的2块磁盘进行分区

[root@shiyueasm~]# fdisk /dev/sdc

Devicecontains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Buildinga new DOS disklabel. Changes will remain in memory only,

until youdecide to write them. After that, of course, the previous

contentwon't be recoverable.

 

Warning:invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

 

Command(m for help): n

Commandaction

   e  extended

   p  primary partition (1-4)

Lastcylinder or +size or +sizeM or +sizeK (1-652, default 652):

Command(m for help): w

[root@shiyueasm~]# fdisk /dev/sdd

3、  上传 oracle asmlibrary rpm包并对上传的包进行安装

[root@shiyueasmu01]# cd asm\ rpm\ for\ rhel4.0/

[root@shiyueasmasm rpm for rhel4.0]# ll

total 236

-rw-r--r--  1 root root 129218 Apr 29  2010oracleasm-2.6.9-42.ELsmp-2.0.3-1.i686.rpm

-rw-r--r--  1 root root 13105 Apr 29  2010oracleasmlib-2.0.4-1.el4.i386.rpm

-rw-r--r--  1 root root 82542 Apr 29  2010oracleasm-support-2.1.3-1.el4.i386.rpm

[root@shiyueasmasm rpm for rhel4.0]# rpm -ivh *

warning:oracleasmlib-2.0.4-1.el4.i386.rpm: V3 DSA signature: NOKEY, key ID b38a8516

4、  配置ASM驱动

[root@shiyueasm~]# /etc/init.d/oracleasm configure

Configuringthe Oracle ASM library driver.

 

This willconfigure the on-boot properties of the Oracle ASM library

driver.  The following questions will determinewhether the driver is

loaded onboot and what permissions it will have. The current values

will beshown in brackets ('[]').  Hitting<ENTER> without typing an

answerwill keep that current value.  Ctrl-Cwill abort.

 

Defaultuser to own the driver interface []: oracle

Defaultgroup to own the driver interface []: oinstall

StartOracle ASM library driver on boot (y/n) [n]: y

Scan forOracle ASM disks on boot (y/n) [y]:

WritingOracle ASM library driver configuration: done

Initializingthe Oracle ASMLib driver: [  OK  ]

Scanning the system for Oracle ASMLibdisks: [  OK  ]

5、  创建ASM磁盘组

[root@shiyueasm~]# /etc/init.d/oracleasm createdisk VOL01 '/dev/sdc1'

Markingdisk "VOL02" as an ASM disk: [ OK  ]

[root@shiyueasm~]# /etc/init.d/oracleasm createdisk VOL02 '/dev/sdd1'

Marking disk "VOL01" as anASM disk: [  OK  ]

6、  手动创建磁盘组参数文件

[oracle@shiyueasm~]$ cd $ORACLE_HOME/dbs

[oracle@shiyueasmdbs]$ ll

total 48

-rw-r--r--  1 oracle oinstall   934 May 26 10:52 db.sql

-rw-rw----  1 oracle oinstall  1544 May 26 10:32 hc_shiyue.dat

-rw-r-----  1 oracle oinstall 12920 May  3  2001initdw.ora

-rw-r-----  1 oracle oinstall  8385 Sep 11 1998 init.ora

-rw-r--r--  1 oracle oinstall   996 May 26 10:31 initshiyue.ora

-rw-rw----  1 oracle oinstall    24 May 26 10:52 lkSHIYUE

-rw-r-----  1 oracle oinstall  1536 May 26 10:32 orapwshiyue

[oracle@shiyueasm dbs]$ viinit+ASM.ora

asm_diskstring=''

background_dump_dest=/u01/admin/shiyueasm/bdump

core_dump_dest=/u01/admin/shiyueasm/cdump

user_dump_dest=/u01/admin/shiyueasm/udump

instance_type='asm'

large_pool_size=20m

remote_login_passwordfile='shared'

7、  创建相关目录

[oracle@shiyueasm~]$ mkdir -p /u01/admin/shiyueasm/bdump

[oracle@shiyueasm~]$ mkdir -p /u01/admin/shiyueasm/cdump

[oracle@shiyueasm ~]$ mkdir -p/u01/admin/shiyueasm/udump

8、  切换至ASM实例

[oracle@shiyueasm ~]$ export ORACLE_SID=+ASM
