[root@rac10 ~]# service ntpd restart
Shutting down ntpd:                                        [FAILED]

8) Disk Partitioning using fdisk

[root@rac10 u01]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

The number of cylinders for this disk is set to 12446.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

Oracle E-Business 12.2 Installation

Disk space

Fresh- PROD 180gb
Vision 350gb

Software Required:

Oracle Enterprise Linux 5.7 (64-bit)
Oracle E-Business suite R12.2 for LinuxX86-64-bit

Hardware Requirement:

Databases Node:
Operating System : Oracle Enterprise Linux 5.7 64bit
Memory               : 16 GB
Hostname : delta001db.oracle.com
IP Address           : 192.168.1.110

Applications Node:
Operating System : Oracle Enterprise Linux 5.2 64bit
Memory : 16 GB
Hostname : delta001app.oracle.com
IP Address : 192.168.1.111

Prerequisite Steps:

1.create OS group, user and directories:

groupadd dbaerp
useradd -g dbaerp oracle
useradd -g dbaerp applmgr

Changing password for user oracle and applmgr.
passwd oracle
passwd applmgr

2.create directories and change permissions:

mkdir -p /u01/ora_prod
mkdir -p /u01/appl_prod
chmod -R 775 /u01/*_prod
chown -R oracle:dbaerp /u01/ora_prod
chown -R applmgr:dbaerp /u01/appl_prod

3.configure kernel parameters (Edit /etc/sysctl.conf file):

#All below kernel parameters are related to oracle EBS - R12.2#################kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmall = 268435456
kernel.shmmax = 429496729
kernel.shmmni = 4096
kernel.sem = 256 32000 100 142
fs.file-max = 327679
net.ipv4.ip_local_port_range = 10000 65000
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_max = 4194304
:wq

[root@delta001 Server]# sysctl -p
net.ipv4.ip_forward = 0
net.ipv4.conf.default.rp_filter = 2
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.shmall = 268435456
kernel.shmmax = 429496729
kernel.shmmni = 4096
kernel.sem = 256 32000 100 142
fs.file-max = 327679
net.ipv4.ip_local_port_range = 10000 65000
net.core.rmem_default = 262144
net.core.wmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_max = 4194304

5.Verify and change Domain Name System (DNS) Resolver Parameters

Two Domain Name System (DNS) resolver parameters (timeout and attempts) are set by default to low values when the operating system is installed. These low values may cause attempted network connections to an Oracle database to fail. If this happens, add or update the following entries to these minimum settings in the /etc/resolv.conf file on each server node:

options attempts:5
options timeout:15

6.Modifying the Number of Open File Descriptors open the /etc/security/limits.conf file and change the existing values for "hard" and "soft" parameters as follows. Restart the system after making changes.

Note: If the current value for any parameter is higher than the value listed in this document, then do not change the value of that parameter.

* hardnofile 65535
* softnofile 4096
* hardnproc 16384
* softnproc 2047

7.Make sure all OS packages exists on the system.

To Check the Package is installed
Use:  rpm –q <pkgname>

To Install the required package
Use: rpm –i<pkg file name>

To Erase the package
Use: rpm –e <pkg name>

The following packages should exists on system for a successful Installation.

openmotif21-2.1.30-11.EL5.i3861
xorg-x11-libs-compat-6.8.2-1.EL.33.0.1.i386

8.checking swap memory should be 16GB or more (20GB is configured)

[root@delta001 ~]# grep SwapTotal /proc/meminfo
SwapTotal:      20482864 kB
[root@delta001 ~]#

9.Verify /etc/hosts file. It should be configured with fully qualified domain name

[root@delta001 ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost
192.168.1.100           detlta001.oracle.com delta001

10.create Inventory and grant 775 permission to Inventory directory

[root@delta001 ~]# cat /etc/oraInst.loc
inventory_loc=/u01/ora_prod/oraInventory/
[root@delta001 ~]# mkdir -p /u01/ora_prod/oraInventory/

11.Verify that the /etc/sysconfig/network file is formatted as follows:

[root@delta001 Server]# more /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=detlta001.oracle.com

12.Create soft link for library as below for 10.1.2 Server:

[root@delta001 Server]# ls -lrt /usr/lib/libXtst.so.6
lrwxrwxrwx 1 root root 16 Sep 29 21:48 /usr/lib/libXtst.so.6 -> libXtst.so.6.1.0
[root@delta001 Server]# unlink /usr/lib/libXtst.so.6
[root@delta001 Server]# ln -s /usr/X11R6/lib/libXtst.so.6.1 /usr/lib/libXtst.so.6
[root@delta001 Server]# ls -lrt /usr/lib/libXtst.so.6
lrwxrwxrwx 1 root root 29 Sep 29 23:34 /usr/lib/libXtst.so.6 -> /usr/X11R6/lib/libXtst.so.6.1
[root@delta001 Server]#
[root@delta001 etc]# ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2
[root@delta001 etc]#

13.Threading model in Linux should be NPTL

[root@delta001 Server]# getconf GNU_LIBPTHREAD_VERSION
NPTL 2.5
[root@delta001 Server]#

14.Prepare Staging Area:

a) Download all required Parts
b) Unzip startHere CD for getting buildStage.sh
c) Execute bulildStage.sh script for creating Stage

15.Unzip startHere CD for getting buildStage.sh

- Create directory for R12 Stage
- unzip parts of StartHere CD in R12 Staging directory

[root@erpnode2 Oracle E-Business Suite 12.2.2]# ls -lrt V35215-*
-rwxrwx--- 1 root vboxsf   85594608 Sep 24 10:13 V35215-01_2of3.zip
-rwxrwx--- 1 root vboxsf  101976210 Sep 24 10:17 V35215-01_3of3.zip

You can install missing packages from dvd. Just mount it and install missing packages using rpm -Uvh command from directory <mount dvd>/Packages or by using yum install command.

First option from dvd
rpm -Uvh/ivh libaio-devel*.x86_64.rpm
rpm -Uvh/ivh ksh*.x86_64.rpm

Second option using yum install command. It requires access to internet.
yum install libaio-devel*.x86_64
yum install ksh*.x86_64

Add following lines in .bash_profile for user oracle

Create directory structure

ORACLE_BASE – /ora01/app/oracle
ORACLE_HOME – /ora01/app/oracle/product/11.2.0/db_1

mkdir -p /ora01/app/oracle/product/11.2.0/db_1

chown oracle:oinstall -R /oracle01

Secure Linux

Disable secure linux by editing the “/etc/selinux/config” file, making sure the SELINUX  flag is set as follows. It requires REBOOT to be effective

SELINUX=permissive

Install database software

Issue the following command to avoid problems with starting binary installation in

graphical mode

xhost +<machine-name>

--in my case it's
xhost +linux.dbaora.com

Let’s start with database software installation as oracle user.

su - oracle

--unzip software 11.2.0.4
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip

--I defined 4 aliases in .bash_profile of user oracle to make
--administration easier :)

[oracle@linux]$ alias envo cdob cdoh tns
alias envo='env | grep ORACLE'
alias cdob='cd $ORACLE_BASE'
alias cdoh='cd $ORACLE_HOME'
alias tns='cd $ORACLE_HOME/network/admin'

--run alias command envo to display environment settings

envo
ORACLE_UNQNAME=ORA11G
ORACLE_SID=ORA11G
ORACLE_BASE=/ora01/app/oracle
ORACLE_HOSTNAME=linux.dbaora.com
ORACLE_HOME=/ora01/app/oracle/product/11.2.0/db_1

--run alias command cdob and cdoh to check ORACLE_BASE, ORACLE_HOME
[oracle@linux]$ cdob
[oracle@linux oracle]$ pwd
/ora01/app/oracle

[oracle@linux db_1]$ cdoh
[oracle@linux db_1]$ pwd
/ora01/app/oracle/product/11.2.0/db_1

--run installation
