Setup OS

– Disable the Firewall

[root@oel6srv01 ~]# service iptables save
[root@oel6srv01 ~]# service iptables stop
[root@oel6srv01 ~]# chkconfig iptables off
[root@oel6srv01 ~]# service iptables status
-- If you are using IPv6 firewall, enter:
 [root@oel6srv01 ~]# service ip6tables save
 [root@oel6srv01 ~]# service ip6tables stop
 [root@oel6srv01 ~]# chkconfig ip6tables off
 [root@oel6srv01 ~]# service ip6tables status


– Disable the SELinux

[root@oel6srv01 ~]# vi /etc/sysconfig/selinux


– DISABLED kdump

[root@oel6srv01 ~]# chkconfig kdump on
[root@oel6srv01 ~]# chkconfig --list |grep kdump
kdump           0:off   1:off   2:off   3:off   4:off   5:off   6:off


– Network Setup

Public Cluster interphases, VIPs and SCAN

Subnet 10.0.0.x
Netmask 255.255.255.0

Private Cluster interphases

Subnet  192.168.0.x
Netmask 255.255.255.0

 


– Kernel add or amend the following lines  to the “/etc/sysctl.conf” file.

# vi /etc/sysctl.conf
fs.aio-max-nr = 1048576
 fs.file-max = 6815744
 kernel.shmall = 2097152
 kernel.shmmax = 1062637568
 kernel.shmmni = 4096
 # semaphores: semmsl, semmns, semopm, semmni
 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
--Activate the current Kernel parameters:
/sbin/sysctl -p

– Add the following lines to /etc/security/limits.conf

# vi  /etc/security/limits.conf
## Go to the end
 grid     soft     nproc      2047
 grid     hard     nproc     16384
 grid     soft     nofile     1024
 grid     hard     nofile    65536
 oracle   soft     nproc      2047
 oracle   hard     nproc     16384
 oracle   soft     nofile     1024
 oracle   hard     nofile    65536

– Add the following line to /etc/pam.d/login

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


– Disable secure linux

–making sure the SELINUX flag is set as follows.

# vi /etc/selinux/config
SELINUX=disabled


– NTP Setup

–If you are using NTP, you must add the “-x” option into the following line in the “/etc/sysconfig/ntpd” file.

# vi /etc/sysconfig/ntpd
OPTIONS="-x -u ntp:ntp -p /var/run/ntpd.pid"
# service ntpd restart
 -- OR STOP NTP SERVER the Grid will start CSSD in Active mode instead of Observe:
 # service ntpd stop
 # chkconfig ntpd off

–Install the cvuqdisk RPM. Without cvuqdisk, Cluster Verification Utility cannot discover shared disks,
–and it raises the following error message “Package cvuqdisk not installed” when Cluster Verification Utility is executed.

–A copy of the cvuqdisk  package is present on the 1st Grid Infrastructure ZIP file.

— Log in as root.

  1. Use the following command to find if you have an existing version of the cvuqdisk package:
# rpm -qi cvuqdisk

2.  If you have an existing version, then enter the following command to deinstall the existing version:

rpm -e cvuqdisk

  1. Set the environment variable CVUQDISK_GRP to point to the group that will own cvuqdisk, typically oinstall. For example:
# CVUQDISK_GRP=oinstall; export CVUQDISK_GRP
4. Install the cvuqdisk package:
rpm -iv package
# rpm -iv cvuqdisk-1.0.9-1.rpm
--OR
you install oracle-rdbms-server-12cR1-preinstall


– OPTIONAL RPMs

--Minimum ODBC Drivers for Oracle and Red Hat Linux 6 on x86-64
 unixODBC-2.2.14-11.el6 (64-bit) or later
 unixODBC-devel-2.2.14-11.el6 (64-bit) or later

– UNIX Groups

/usr/sbin/groupadd -g 1000 oinstall
/usr/sbin/groupadd -g 1001 asmadmin
/usr/sbin/groupadd -g 1002 dba
/usr/sbin/groupadd -g 1003 asmdba
/usr/sbin/groupadd -g 1004 asmoper

–New optional roles which grant access to specific features like Data Guard, RMAN and Security have been added in 12c, but not implemented in this example.


– UNIX Users

useradd -u 1100 -g oinstall -G asmadmin,asmdba,asmoper grid
useradd -u 1101 -g oinstall -G asmdba,dba oracle


– Set SSH timeout wait to unlimited

# vi /etc/ssh/sshd_config
LoginGraceTime 0

 


– Create the u01 file system

[root@oel6srv01 ~]# fdisk /dev/sdb
The number of cylinders for this disk is set to 2871.
 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)
