rhel5.8 Installing Oracle 10g ASM

1. All configurations are the same as the file system . 2. Planning:

Added 8 small plates, ASM for experiment using Asmlib Drive (rhel6 no longer supports Asmlib drive), 2 methods for bare devices (Rowdevice and Udev)

Three discs using Asmlib, two using Rowdevice, two using Udev 2. Partitioning

Create an ASM disk group

(1) The following is the way to create a disk group through Asmlib, creating

/etc/init.d/oracleasm Configure

/etc/init.d/oracleasm Createdisk V1/DEV/SDB1

/etc/init.d/oracleasm Createdisk V2/DEV/SDC1

/etc/init.d/oracleasm Createdisk V3/DEV/SDD1

/etc/init.d/oracleasm Scandisks

/etc/init.d/oracleasm Listdisks

(2) The following method is configured by Rowdeviece mode

Configuration file/etc/sysconfig/rawdevices

Add to:

/dev/raw/raw1/dev/sde1
/dev/raw/raw2/dev/sdf1
/dev/raw/raw3/dev/sdg1

Start the service

/etc/init.d/rawdevices start

/dev/raw/raw2:bound to Major 8, minor 81
/dev/raw/raw3:bound to Major 8, minor 97

Modify Permissions

Chown oracle:oinstall/dev/raw/raw{1,2,3}

chmod 660/dev/raw/raw{1,2,3}

(3) Using Udev method

[Email protected] raw]# Vi/etc/udev/rules.d/60-raw.rules
# Enter Raw device bindings here.

# A example would be:
# action== "Add", kernel== "SDA", run+= "/bin/raw/dev/raw/raw1%N"
# to BIND/DEV/RAW/RAW1 TO/DEV/SDA, or
# action== "Add", env{major}== "8", env{minor}== "1", run+= "/bin/raw/dev/raw/raw5%M%M"
# to BIND/DEV/RAW/RAW5 to the device with major 8, minor 1.
action== "Add", kernel== "Sdh1", run+= "/bin/raw/dev/raw/raw4%N"
action== "Add", kernel== "Sdi1", run+= "/bin/raw/dev/raw/raw5%N"

Restart Service

The following raw4, RAW5 for the use of Udev binding device, the advantage is that you can directly attach permissions and groups directly to the bare device, reboot does not need to modify the permissions again, but with the above Rawdevice way, you need to manually modify the permissions of the bare device.

The bare devices that can now be used by ASM disks are:

3 Disk groups V1 V2 V3

3 pieces of rawdevece configuration of the bare device

2. Udev configuration of bare device 3, start to install Oracle soft

Execute Runinstaller ( it is recommended that you do not create a new ASM disk and instance when installing the software, and then build the ASM instance when dbca the repository )

Create ASM at DBCA

Visible, all the bare devices have been identified

, OK, start selecting the required disk device, and click Next to start the installation.

4. Some problems encountered during installation first, DBCA configuring ASM instances

Solve

Please run the following batch files in the $ORACLE _home/bin directory (under root user)

Localconfig Delete

[[email protected] bin]#./localconfig Delete

This'll help you to solve your problem

The problem is solved, and the ASM instance can start

If it cannot be performed, reboot the system. Second, when the above problem is resolved, the following ora-00600 error is reported when the ASM instance is created

Solve:

Looked it up on the Internet. Modifying the hostname will cause this problem. And friends confirmed a bit, indeed have modified the machine's hostname, the reason is clear, to begin to solve is very simple, modify the/etc/hosts file, add Hostanme can.

Other Notes:
Description of document Doc id:note:5486074.8 on Oracle's Meatlink: This error message occurs when Oracle cannot determine the hostname or network address.
Oracle resolves this bug in 10.2.0.4 and 11.1.0.6. Oracle's Metalink indicates that this error could have been caused before 10.2.0.4.
