10g installation document

We should install Rpm’s
[root@rac21 ~]#rpm –ivh compat-gcc-c++-7.3-2.96.128.i386.rpm
Configuring Network
[root@rac21 ~]#vi /etc/hosts
192.168.0.1 orawave1.appsdba.com orawave1
:wq
[root@rac21 ~]#service network restart
NOTE: After that you have to check ip and hostname
[root@rac21 ~]#ifconfig --------to check ip address
[root@rac21 ~]#hostname –i
[root@rac21 ~]#hostname -d
[root@rac21 ~]#hostname
[root@rac21 ~]#ping 192.168.0.1

We have to added following lines to sysctl.conf
]#vi /etc/sysctl.conf

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 = 1048576
net.core.rmem_max = 1048576
net.core.wmem_default = 262144
net.core.wmem_max = 262144
:wq

[root@rac21 ~]#sysctl –p
(or)
[root@rac21 ~]#/sbin/sysctl –p

For Oracle 10g we should create one group and one user
NOTE: Group should be DBA or OINSTALL
[root@rac21 ~]#groupadd -g 400 dba
[root@rac21 ~]#useradd -u 500 -g dba -d /u01/oracle oracle

Then need to change Owner and permission by using chown and chmod
[root@rac21 ~]#chown –R oracle:dba /u01/oracle
[root@rac21 ~]#chmod –R 777 /u01/oracle

Enable GUI by running Xhost +[root@rac21 ~]#xhost +

[root@rac21 ~]#vi /etc/oraInst.loc

inventory_loc=/u01/oracle/10.2.0/oraInventory
:wq

Switch to user for setting environment
[root@rac21 ~]#su - oracle
[oracle@oracle~]$ls -a
[oracle@oracle~]$vi .bash_profile

export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=/u01/oracle/10.2.0
export PATH=$PATH:$ORACLE_HOME/bin:.
export LD_ASSUME_KERNEL=2.4.19
export ORACLE_SID=prod
:wq

[oracle@oracle~]$echo $ ORACLE_BASE
/u01/oracle
[oracle@oracle~]$ echo $ ORACLE_HOME
/u01/oracle/10.2.0
[oracle@oracle~]$ echo $ ORACLE_SID
prod
[oracle@oracle~]$ echo $ PATH
[oracle@oracle~]$cd /stage/10g/database
[oracle@oracle~]$ ./runInstaller

After ending the installation OUI will give one script that is root.sh
We should run as a root user
[root@rac21 ~]# sh /u01/oracle/10.2.0/root.sh
