Preparation of Oracle 10g RAC cluster installation deployment

I. Basic ENVIRONMENTAL requirements

System environment:

System version: Rhel5u8 x86_64

Oracle Version: Oracle 10.2.1

IP Address

ODB1 192.168.100.144

192.168.101.144

ODB2 192.168.100.143

192.168.101.143

Server Shutdown selinux/iptables

Second, preparatory work

Modify the host name of two computers

ODB1 Odb1-priv ODB1-VIP

OBD2 Odb2-priv ODB2-VIP

Configure Yum source code, to ensure that the data package are fully installed, Oraclerac the most annoying packet, the problem, most of them are due to the RPM package caused by

Create Oracle Users and Oinstall dba two groups on two machines respectively

Prepare six shared disks, which we can simulate using VirtualBox in this experiment, where we can use EMC NetApp to plan

DATAX2 10G Data disk size according to business

OCRX2 512M Cluster Information registration disk

Virdiskx3 512M

It should be noted that Virtualdis is not supported in oracle11g, only ASM is supported

Do not want to format the hard disk, format only need to configure the test on a single machine

Configure bidirectional SSH without password authentication,

SSH requires two machines to connect to each other and requires SSH to be able to connect SSH itself, or it will complain at the Oracle cluster node

Create raw (bare) devices, you need to modify two profiles on the node of the RAC machine

You also need to pay attention to the issue of raw permissions Chmodchown

Note: You need the same number of raw device port numbers on either side, or you will get an error.

For example: We are on the node a RAW1 corresponds to the port1, then we need to RAW1 on node B corresponding to the PORT1, the port can not be wrong. Or there will be an error.
