Simple configuration of ASM

Simple configuration of ASM

Environment Description

System: Red Hat Enterprise Linux Server release 5.4 (Tikanga)
Database Version: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 add Disk

Add three hard disks for the ASM disk group:

It is best to make the three disks as large as they are, which may easily lead to hot spot competition during redundancy, increase the disk I/O, and affect performance.

Restart the system. Format: Disk

Install Oracle 11gR2 (x64) in CentOS 6.4)

Steps for installing Oracle 11gR2 in vmwarevm

Oracle 10g R2 create ASM instance Step By Step

After the system is started, fdisk-l is used to view the attached disk. fdisk/dev/sdb is used to format the sdb.

[Root @ localhost ~] # Fdisk/dev/sdb

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

Building a new DOS disklabel. Changes will remain in memory only,

Until you decide to write them. After that, of course, the previous

Content won't be recoverable.

The number of cylinders for this disk is set to 1044.

There is nothing wrong with that, but this is larger than 1024,

And coshould in certain setups cause problems:

1) software that runs at boot time (e.g., old versions of LILO)

2) booting and partitioning software from other OSs

(E.g., dos fdisk, OS/2 FDISK)

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

We can see the following information: sdb, sbc, and sdd disks will be used for the ASM disk.
