Oracle 11g RAC Installation Log in CentOS 5.5

Server
DELL R410 2
Cpu inter E5620. 4 GHz 12M4C
MEM 64G
DISK 300 GB

Memory
DS3512
DISK 600G * 12 RAID5

(Because JS is shoddy, it took a month to solve the problem on the server fiber optic card.

Problem:
1. storage cannot be found on the server from time to time;
2. The optical fiber card interface cannot be found at the memory configuration end.
3. After the server is restarted, the memory cannot be found. It can be found only after the memory is restarted.


Finally, I used a 4 GB disk and gave it to us as 8 GB. The speed must be discounted.
That's so angry. Using different hardware products is troublesome)



Software environment:
CentOS 5.5 64bit
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 (64-bit)


1. Local disk partition of the server:

Disk/dev/sda: 300.0 GB, 300000000000 bytes
255 heads, 63 sectors/track, 36472 cylinders
Units = cylinders of 16065*512 = 8225280 bytes

Device Boot Start End Blocks Id System
/Dev/sda1*1 25 200781 83 Linux
/Dev/sda2 26 36472 292760527 + 8e Linux LVM


The LVM partition is used, and then the volume is used.
The LVM information is as follows:

2. IP planning

[Root @ rac2 app] # cat/etc/hosts
# Do not remove the following line, or various programs
# That require network functionality will fail.
127.0.0.1 localhost. localdomain localhost
#: 1 localhost6.localdomain6 localhost6


# Public ip
192.168.18.101 rac1
192.168.18.103 rac2

# Priv ip
The 192.168.0.101 rac1-private
192.168.0.103 rac2-private

# Vip ip
192.168.18.121 rac1-vip
192.168.18.123 rac2-vip

# Scan ip
192.168.18.100 rac-scan

(Note: All host names must conform to the RFC 952 standard,
Which permits alphanumeric characters, Host name using underscores ("_")
Are not allowed. HOSTS file does not support the "_" character)

Vi/etc/pam. d/login

# ORACLE SETTING
Session required pam_limits.so

# Vi/etc/sysctl. conf

# ORACLE SETTING
Fs. aio-max-nr = 1048576
Fs. file-max = 6815744

Net. core. rmem_max = 4194304
Net. core. wmem_default = 262144
Net. core. wmem_max = 1048586


5. settings required for gird time synchronization (11gR2 new check item)

# Network Time Protocol Setting
/Sbin/service ntpd stop
Chkconfig ntpd off
# Rm/etc/ntp. conf
Mv/etc/ntp. conf/etc/ntp.conf.org


Select whether to enable or disable the SELINUX working mode (you 'd better restart the operating system after modifying this option)

[Root @ oracle ~] # Vi/etc/selinux/config

# Set SELINUX to disabled

SELINUX = disabled

6. operating system version:

[Root @ rac1 ~] # Lsb_release-
LSB Version: core-3.1-amd64: core-3.1-ia32: core-3.1-noarch: graphics-3.1-amd64: graphics-3.1-ia32: graphics-3.1-noarch:

[Root @ rac1 ~] #

7. Modify the release version of the system

[Root @ oracle ~] # Vi/etc/RedHat-release

Change CentOS release 5 (Final)
# CentOS release 5 (Final)
Red Hat Enterprise Linux AS release 5 (Nahant Update 5)

(Because oracle has not released CentOS version of oracle)
