COPY ALL RPM FILES FROM LINUX CD
-------------------------------------------------------

copy all rpm files to local disk in folder "repo"

$cp /oracle/server/*.rpm   /u02/repo

CREATE A REPOSITORY FOR RPM

---------------------------------------------------

#cd /U02

#createrepo  -v repo

#cd  /etc/yum.repos.d

#vi reposcript.repo

[mainrepo]

name=mainrepo

baseurl=file:///mnt/repo

enabled=1

gpgcheck=0

:wq

#yum clean all

#yum list

install required rpm:

---------------------

Goto ”repo” folder

#cd  /u02/repo

Manual Setup

Oracle recommend the following minimum parameter settings.

#vi     /etc/sysctl.conf

fs.suid_dumpable = 1

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 268435456

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500

net.core.rmem_default=262144

net.core.rmem_max=4194304

net.core.wmem_default=262144

net.core.wmem_max=1048586

Run the following command to change the current kernel parameters.

#/sbin/sysctl   -p

#vi    /etc/security/limits.conf

oracle              soft    nproc   2047

oracle              hard    nproc   16384

oracle              soft    nofile  4096

oracle              hard    nofile  65536

oracle              soft    stack   10240

Set secure Linux to permissive by editing the     "/etc/selinux/config" file

#vi   /etc/selinux/config

SELINUX=disable

Create the new groups and users.

#groupadd dba

#useradd -g dba oracle

#passwd oracle

Create the directories in which the Oracle software will be installed.

#mkdir -p /u01/app/oracle/product/11.2.0/db_1

#chown -R oracle:dba /u01

#chmod -R 775 /u01

Copy Oracle Database Software into /u02 mount point.
#chown -R oracle:dba /u02
#chmod -R 777 /u02

Login as root and issue the following command.

#xhost +

Login as the oracle user and add the following lines at the end of the ".bash_profile" file, remembering to adjust them for your specific installation.

#su – oracle

$vi  db.env

export ORACLE_BASE=/u01/app/oracle;

export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1;

export PATH=/usr/sbin:$PATH;

export PATH=$ORACLE_HOME/bin:$PATH;

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;

export ORACLE_SID=ORCL;

:wq

$.   db.env
