Manually create an Oracle 10g ASM Disk

Prepare the environment:

Oracle 10g online documentation, host with 10g database software configured, oracleasm library rpm package, 2 5 Gb hard disks

1. View local disk Information

[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

 

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

2. Partition the two newly added disks.

3. Upload the oracle asmlibrary rpm package and install the uploaded package

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

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

Total 236

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

4. Configure the ASM driver

[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

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. Create an ASM disk group

[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. manually create a parameter file for the disk group

[Oracle @ shiyueasm ~] $ Cd $ ORACLE_HOME/dbs

[Oracle @ shiyueasmdbs] $ ll

User_dump_dest =/u01/admin/shiyueasm/udump

Instance_type = 'asm'

Large_pool_size = 20 m

7. Create related directories

[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. Switch to the ASM instance

[Oracle @ shiyueasm ~] $ Export ORACLE_SID = + ASM
