Easy steps to install ORACLE10GR2 on 64-bit RHEL5.5

1) installation of the required RPM:

# cd/media/rhel_5.5 x86_64 dvd/server
rpm-ivh compat-libstdc++-33-3.2.3-61.i386.rpm rpm-ivh compat-libstdc+
+-33-3.2.3-61.x86_64.rpm 
rpm-ivh gcc-c++-4.1.2-48.el5.x86_64.rpm 
rpm-ivh libstdc++- devel-4.1.2-48.el5.x86_64.rpm 
rpm-ivh glibc-headers-2.5-49.x86_64.rpm 
rpm-ivh glibc-devel-2.5-49.x86_64. RPM 
rpm-ivh glibc-devel-2.5-49.i386.rpm 
rpm-ivh libgomp-4.4.0-6.el5.x86_64.rpm 
RPM-IVH gcc-4.1.2-48.el5.x86_64.rpm 
rpm-ivh libxp-1.0.0-8.1.el5.i386.rpm 
rpm-ivh sysstat-7.0.2-3.el5.x86_64.rpm 
rpm-ivh util-linux-2.13-0.52.el5_4.1.x86_64.rpm 
rpm-ivh kernel-headers-2.6.18-194.el5.x86_64.rpm

Verifying Package Installation:

2 Create installation groups and users:

# groupadd-g 1000 oinstall
# groupadd-g 1001 DBAs
# groupadd-g 1002 Oper
# useradd-u 1000-g oinstall-g DB A,oper Oracle
# passwd Oracle

3 Create the installation directory and set the appropriate permissions:

# mkdir-p/u01/app/oracle

# Chown-r Oracle:oinstall/u01

# Chmod-r 775/u01

4) Adjust kernel parameters:

# vim/etc/sysctl.conf
Kernel.sem = 32000 128 Kernel.shmmax = 2147483648 Kernel.shmmni
= 4096
ker Nel.shmall = 2097152
Fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
Net.core.rmem_max = 2097152
net.core.wmem_default = 262144 Net.core.wmem_max
= 262144

To bring the adjustment into effect:

Sysctl-p

5) Adjust the shell operation parameters:

#/etc/security/limits.conf
Oracle              soft    nproc   2047
Oracle              hard    nproc
16384 Oracle              Soft    nofile  1024
Oracle              hard    nofile  65536

Load Verification Module:

# Vim/etc/pam.d/login
session    required     pam_limits.so

Adjust the maximum number of processes (U) and Files (n) (for bash) that Oracle users can open:

# vim/etc/profile
If [$USER = "Oracle"]; then
        if [$SHELL = "/bin/ksh"]; then
              ulimit-p 16384
              It-n 65536
        Else
              ulimit-u 16384-n 65536
        fi
fi

6 Set oracle_base environment variable

$ oracle_base=/u01/app/oracle; Export Oracle_base

7) Start Installation:
