Step18:

Change your domain

If all is done above you can transfer the DB software to the Linux machine

Now you can follow the below steps as root user.

1)add the below groups

groupadd -g 54321 install

groupadd -g 54322 dba

groupadd -g 54323 oper

groupadd -g 54324 backupdba

groupadd -g 54325 dgdba

groupadd -g 54326 kmdba

groupadd -g 54327 asmdba

groupadd -g 54328 asmoper

groupadd -g 54329 asmadmin

useradd -u 54321 -g oinstall -G dba,oper,backupdba,dgdba,kmdba oracle

passwd oracle

2)vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

172.20.10.10    oracle.localdomain      oracle.localdomain

3)Add the following line at the end of the fstab file:(using vim /etc/fstab)

none                    /dev/shm                tmpfs   size=4096M      0 0

4)Using any text editor, create or edit the vim /etc/sysctl.conf file, and add or edit lines 

similar to the following:

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.shmall = 4294967296

fs.file-max = 6815744

kernel.sem = 250 32000 100 128

kernel.shmmni = 4096

kernel.shmmax = 4398046511104

kernel.panic_on_oops = 1

net.core.rmem_default = 262144

net.core.rmem_max = 4194304

net.core.wmem_default = 262144

net.core.wmem_max = 1048576

fs.aio-max-nr = 1048576

net.ipv4.ip_local_port_range = 9000 65500

5).Run the following command to change the current kernel parameters:(using terminal)

/sbin/sysctl -p

6)Add following lines to set shell limits for user oracle in file vim /etc/security/limits.conf

# shell limits for users oracle 12gR1

oracle   soft   nofile   1024

oracle   hard   nofile   65536

oracle   soft   nproc    16384

oracle   hard   nproc    16384

oracle   soft   stack    10240

oracle   hard   stack    32768

oracle   hard   memlock  134217728

oracle   soft   memlock  134217728

7)cd /run/media/root/OL-7.2 Server.x86_64/Packages or /run/media/root/OL-7.6 Server.x86_64/Packages

rpm -ivh createrepo-0.9.9-23.el7.noarch.rpm

rpm -ivh vsftpd-3.0.2-10.el7.x86_64.rpm

8)[root@oracle Packages]# rpm -ivh createrepo-0.9.9-23.el7.noarch.rpm

warning: createrepo-0.9.9-23.el7.noarch.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

9) cp -r /run/media/ramesh/OL-7.2 Server.x86_64/Packages/ /var/ftp/pub/

10)

cd /var/ftp/pub/

createrepo -v Packages

cd

11)Create Yum repository:

Create and Add the following lines to the /etc/yum.repos.d/server.repo file:(using vim /etc/yum.repos.d/server.repo)

[server]

name=oracle12c

baseurl=file:///var/ftp/pub/Packages

gpgcheck=0

enabled

After insert the lines save the file using press ESC and type :wq then press enter.

12)

And to remove file

cd /etc/yum.repos.d

rm -rvf public*

yum install ksh* -y

yum install libaio* -y

yum install libgcc* -y

yum install libstdc++* -y

yum install make* -y

yum install sysstat* -y

yum install unix* -y

15) For the initial setup of the ASM Disks, execute these commands:(using terminal) 

# Create the directory in which the flat files will reside

mkdir -p /u01/app/oracle

chown -R oracle:oinstall /u01

chmod -R 775 /u01

16) For the initial setup of the ASM Disks, execute these commands:(using terminal) 

# Create the directory in which the flat files will reside

mkdir -p /u01/app/oracle

chown -R oracle:oinstall /u01

chmod -R 775 /u01

17)Change the setting of SELinux to permissive by editing the "vim /etc/selinux/config" file, making sure the SELINUX flag is set as follows.

SELINUX=permissive

18)If you have the Linux firewall enabled, you will need to disable or configure it, as shown here or here. The following is an example of disabling the firewall.

systemctl stop firewalld

systemctl disable firewalls

If you are done with all the above steps Please login the server and unzip those files (root user)

[root@oracle ~]# cd /u01/

[root@oracle u01]#

[root@oracle u01]#

[root@oracle u01]# ls -lrth

total 2.6G
