Recently in the unit of a DELLT710_x64 machine on the layout of a Oracle11g-1_64, from the Internet to check a lot of information, comprehensive installation was successful, the following is the installation steps summary, to provide help to beginners who are as confused as I do, my machine configuration is as follows: SERVER: DELLT710-64 bit CPU: E552064 bit x 2 memory: 8g Hard Disk: STA1T x 3 raid 52t Operating System: RedHatlinux5.4 Hard Disk
Recently a Oracle11g-1_64 has been deployed on a DELL T710_x64 machine in the unit, a lot of information from the Internet, comprehensive installation was successful, the following is the installation steps summary, my machine configuration is as follows:
Server: DELL T710-64 bit
CPU: E5520 64-bit × 2
Memory: 8 GB
Hard Disk: 1 Tb x 3 RAID 5 2 TB
Operating System: RedHat linux 5.4
Hard Disk Partition:
/: 60 GB
/Boot/: 200 m
/Usr/: 30G
/Swap/: 20G
/Tmp/: 10G
/Home/: 40 GB
/Ora/: 120G; oracle11g-1 system and data files are all in this partition
/Data/: 1.5 TB
.
.
Follow these steps:
1. Fully install the Redhat Linux server 5.4 _ X64 Operating System
(1) Oracle11g-1: Download oracle requires a registered account
Http://www.oracle.com/technology/software/products/database/oracle11g/111060_linuxsoft.html
2. Modify the host configuration file (root identity)
# Vi/etc/hosts
# Do not remove the following line, or various programs
# That require network functionality will fail.
# Change the IP address to the server address
192.168.xx.xx localhost
4. Modify kernel parameters (root identity)
# Vi/etc/sysctl. conf
Add the following code: (my server memory is 8 GB. If it is smaller than this number, you need to modify the following parameters)
Kernel. sem = 250 32000 100 128 # maximum number of signal objects for each signal object set; Maximum number of signals within the system range
Net. ipv4.ip _ local_port_range = 1024 65000 # IPv4 port range available for Applications
Net. core. rmem_default = 4194304 # default value of the socket receiving buffer size
Net. core. rmem_max = 4194304 # maximum size of the socket receiving buffer
Net. core. wmem_default = 262144 # default value of the socket sending buffer size
Net. core. wmem_max = 262144 # maximum size of the socket sending Buffer
# Make sysctl-p effective
After execution, the following information is displayed:
Net. ipv4.ip _ forward = 0
Net. ipv4.conf. default. rp_filter = 1
Net. ipv4.conf. default. accept_source_route = 0
Kernel. sysrq = 0
Kernel. core_uses_pid = 1
Net. ipv4.tcp _ syncookies = 1
Kernel. msgmnb = 65536
Kernel. msgmax = 65536
Kernel. shmmax = 4294967295
Kernel. shmall = 268435456
Kernel. sem = 250 32000 100 128
Net. ipv4.ip _ local_port_range = 1024 65000
Net. core. rmem_default = 4194304
Net. core. rmem_max = 4194304
Net. core. wmem_default = 262144
Net. core. wmem_max = 262144
5. Create oracle users and groups
# Groupadd oinstall
# Groupadd dba
# Groupadd rule
# Useradd-g oinstall-G dba, role oracle
# Passwd oracle (set the oracle account password)
6. Verify the nobody user:
# Id nobody
Shown as follows:
Uid = 99 (nobody) gid = 99 (nobody) groups = 99 (nobody)
7. Grant the. ora partition write permission to the oracle account
# Chown-R oracle: oinstall/ora
