Selinux
[root@12Cmachine]# cat /etc/selinux/config
SELINUX=
enforcing ( default)
[root@12Cmachine]#
setenforce Permissive
setenforce:
SELinux is disabled
[root@12Cmachine]# cat /etc/selinux/config
# This
file controls the state of SELinux on the system.
#
SELINUX= can take one of these three values:
# enforcing - SELinux security policy is
enforced.
# permissive - SELinux prints warnings
instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=permissive
#
SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are
protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
Create user and group:-
[root@12Cmachine]#
groupadd –g 501 orainstall
[root@12Cmachine]#
groupadd –g 601 dba
[root@12Cmachine]#
useradd –g orainstall –G dba oracle
[root@12Cmachine]#
egroup ‘orainstall|dba’ /etc/group
orainstall:x:501:
dba:x:601:oracle
[root@12Cmachine]#
id oracle
uid=500(oracle) gid=501(orainstall)
groups=501(orainstall),502(dba)
Change file
system ownership:-
Note: - here we
have given File System (/u002) ownership to ORACLE user.
[root@12Cmachine]#
chown –R oracle:oinstall oracle
Create directory
structure and login profile:-
[root@12Cmachine]#
su - oracle
Password:
----password------
Directory:-
[oracle@12Cmachine]#
mkdir –p /u002/app/oracle
[oracle@12Cmachine]#
mkdir –p /u002/app/oraInventory
Profile:-
[oracle@12Cmachine]#
vi .bash_profile
# Oracle env Settings
TMP=/tmp; export
TMP
TMPDIR=$TMP;
export TMPDIR

Unzipping oracle software patches:-
[oracle@12Cmachine]#
cd /media
-rwxrwxrwx. 1 oracle orainstall 1673544724 Nov 5 22:39
linuxamd64_12102_database_1of2.zip
-rwxrwxrwx. 1 oracle orainstall 1014530602 Nov 5 23:02
linuxamd64_12102_database_2of2.zip
[oracle@12Cmachine]#
unzip linuxamd64_12102_database_1of2.zip –d /u002
[oracle@12Cmachine]#
unzip linuxamd64_12102_database_2of2.zip -d /u002
Steps 3 Install oracle 12.1.0.2:-
[oracle@12Cmachine]#
/u002/database
