Installing Oracle 10g RAC Based on Linux (RHEL 5.5)

This article describes how to use vmware server in Red Hat 5.5 to install Oracle 10g RAC (OCFS + ASM). This article assumes that your RHEL5 has been installed, the specific configuration and installation process of Linux are listed below.

I. installation environment

1. host operating system environment overview:

Host Name	Operating System	Processor	Memory	Disk	Nic
Robinson	Windows XP Professional Service Pack 3	Intel Core 2 dual-core 1.6 GHZ	3 GB DDR2 667 MHz	500 GB, SATA 7200 RPM	Intel Pro/1000 MT

 

2. Overview of the customer's operating system environment:

Host Name	Operating System	Processor	Memory
Node1	RHEL 5.5 (32-bit)	1	800 MB
Node2	RHEL 5.5 (32-bit)	1	800 MB

 

3. Overview of the Virtual Disk layout:

Virtual Disks on the host operating system	Virtual Disks on the customer's Operating System	Virtual Device Node	Size (MB)	Description
E: \ VirtualMachine \ Node1 \ localdisk. vmdk	/Dev/sda1 /Dev/sda2 /Dev/sda3	SCSI 0: 0	20	"/" Mount point Swap space Oracle binary
E: \ VirtualMachine \ sharedstorage \ ocfs2disk. vmdk	/Dev/sdb	SCSI 1:0	536	OCFS2 Disk
E: \ VirtualMachine \ sharedstorage \ asmdisk1.vmdk	/Dev/sdc	SCSI 1:1	4294	ASM disk Group 1
E: \ VirtualMachine \ sharedstorage \ asmdisk2.vmdk	/Dev/sdd	SCSI	4294	ASM disk Group 1
E: \ VirtualMachine \ sharedstorage \ asmdisk3.vmdk	/Dev/sde	SCSI 1: 3	3221	ASM flash back recovery area

(To configure shared storage, the customer's OS cannot share the same SCSI bus with the shared storage. Specifies that the client OS uses SCSI0 and the shared disk uses scsi1 .)

 

4. RAC database environment overview:

Host Name	ASM instance name	RAC Instance name	Database Name	Database File Storage	OCR and Voting Disk)
Node1	+ ASM1	Ora10g1	Ora10g	ASM	OCFS2
Node2	+ ASM2	Ora10g2	Ora10g	ASM	OCFS2

 

Ii. Virtual Machine Settings

1. Virtual Machine creation is not demonstrated here. It is important to set virtual machine parameters. After the first virtual machine is added, modify the following parameters:

Modify E: \ VirtualMachine \ Node1 \ node1.vmx

Add the following content:

Disk. locking = "FALSE"

DiskLib. dataCacheMaxSize = "0"

DiskLib. datachemaxreadaheadsize = "0"

DiskLib. dataCacheMinReadAheadSize = "0"

DiskLib. dataCachePageSize = "4096"

DiskLib. maxUnsyncedWrites = "0"

 

Scsi1.present = "TRUE"

Scsi1.virtualDev = "lsilogic"

Scsi1.sharedBus = "VIRTUAL"

 

Scsi1: 0. deviceType = "disk"

Scsi1: 1. deviceType = "disk"

Scsi1: 2. deviceType = "disk"

Scsi1: 3. deviceType = "disk"

 

Delete scsi1.sharedBus = "none" in the original file"

If more scsi devices are used in the virtual machine you have installed, add the middle section and change it to the corresponding scsi as the corresponding number.

2. You can use a virtual machine to set the time to synchronize the host and client, or configure ntp. conf to set the time synchronization service. The following uses vmware to configure time synchronization.

Run "vmware-toolbox" to display the VMware Tools Properties window. On the Options tab, select Time synchronization between the virtual machine and the host operating system. You should find that the tools. syncTime = "TRUE" parameter has been appended to the virtual machine configuration file E: \ VirtualMachine \ Node1 \ node1.vmx.

Edit/Boot/grub. confAnd set"Clock = pit nosmp noapic nolapic"Add to read Kernel/Boot/. You have added the option to two kernels. Now you only need to change the specific kernel.

# Boot =/dev/sda

Default = 0

Timeout = 5

Splashimage = (hd0, 0)/boot/grub/splash.xpm.gz
