Detailed steps for installing Oracle 10 Gb in RHEL5.2 System

I. Check hardware requirements
 
Memory Requirements (at least 1 GB) # grep MemTotal/proc/meminfo
Swap zone requirements # grep SwapTotal/proc/meminfo
/Tmp directory (at least MB space) # df-m/tmp
Ii. system software requirements
 
View the operating system version # cat/et c/issue
View the kernel version # uname-r
System software package Query
Binutils
Compat-db
Compat-libstdc ++-296
Control-center
Gcc
Gcc-c ++
Glibc
Glibc-common
Gnome-libs
Libstdc ++
Listdc ++-devel
Make
Pdksh
Sysstat
Xscreensaver

Libaio-0.3.106
Modify the/etc/hosts file (add the correspondence between the local host name and the IP address)
 
# Vi/etc/hosts
100.100.100.200 linux5
3. Create users and groups
#/Usr/sbin/groupadd oinstall
#/Usr/sbin/groupdd dba
#/Usr/sbin/groupadd Partition
# Useradd-g oinstall-G dba, role Oracle
# Passwd oracle
4. confirm the existence of the user's nobody
# Id nobody
5. Adjust Kernel Parameters
Modify the/et c/sysctl. conf file (Add the following content to the end of the file)
Kernel. core_uses_pid = 1
Kernel. shmall = 2097152
Kernel. shmmax = 2147483648
Kernel. shmmni = 4096
Kernel. sem = 250 32000 100 128
Fs. file-max = 65536
Net. ipv4.ip _ local_port_range = 1024 65000
Net. core. rmem_default = 10248576
Net. core. rmem_max = 1048576
Net. core. wmem_default = 262144
Net. core. wmem_max = 26144
Make kernel parameters take effect immediately
# Sysctl-p
6. Modify user restrictions
Edit the/etc/security/limits. conf file (Add the following content at the end of the file) oracle soft nproc 2047
Hard nproc 16384
Oracle soft nofile 1024
Oracle hard nofile 65536
Edit the/etc/pam. d/login file (Add the following content at the end of the file)
Session required pam_selinux.so open
Session required/lib/security/pam_limits.so
Session required pam_limits.so
Edit the/etc/profile file (Add the following content at the end of the file)
If [$ USER = "oracle"]; then
If [$ SHELL = "/bin/ksh"]; then
Ulimit-p 16384
Ulimit-n 65536
Else
Ulimit-u 16384-n 65536
Fi
Fi
Edit the/etc/csh. login file
If ($ USER = "oracle") then
Limit maxproc 16384
Limit descriptors 65536
Endif
 
7. Create an oracle software installation directory
[Root @ linux5 ~] # Mkdir-p/db/oracle
[Root @ linux5 ~] # Chown-R oracle: oinstall/db/oracle/
[Root @ linux5 ~] # Chmod-R 775/db/oracle/
8. Set oracle user environment variables (Add the following content)
[Root @ linux5 ~] # Su-oracle
[Oracle @ linux5 ~] $ Vi. bash_profile
Umake 022
ORACLE_BASE =/db/oracle
ORACLE_HOME = $ ORACLE_BASE/product/10.2.0/db_1
ORACLE_SID = yang
PATH = $ ORACLE_HOME/bin: $ PATH :.
Export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
9. Upload the oracle database software
Start the vsftpd service on a linux Server
[Root @ linux5 ~] # Service vsftpd start
Starting vsftpd for vsftpd: [OK]
Upload the oracle database software over ftp on a windows Host

11. Install the oracle database
Because orcale10 does not support RHEL5, you need to change/etc/redhat_real.pdf to Red Hat Enterprise Linux Server release 5 (Tikanga) to Red Hat Enterprise Linux Server release 4 (Tikanga)
# Cd/home/oracle/database
#./RunInstaller
1. Do not select "create starter database"
2. Check the parameter file added earlier
3. Install the agent by default.
4. When the installation is complete, a prompt is displayed to execute the script file as the root user.
[Oracle @ linux5 db_1] $ su-
Password:
[Root @ linux5 ~] # Sh/db/oracle/product/10.2.0/db_1/root. sh
[Root @ linux5 ~] # Sh/db/oracle/oraInventory/orainstRoot. sh
Click OK after the execution is complete.
Exit
12. Configure the listener
1. Enable the configuration listening Assistant
[Oracle @ linux5 ~] $ Netca
2. click next.
3. Complete!
