Installation of Oracle-12C database




 

Create groups, user and directories


#groupadd -g 54321 oinstall
#groupadd -g 54322 dba
#groupadd -g 54323 oper
#useradd -u 54321 -g oinstall -G dba,oper oracle
#passwd xxxxxx

#mkdir -p /u01/app/oracle/product/12.1.0
#chown -R oracle:oinstall /u01
#chmod -R 775 /u01

Pre-Requisite check for 12CR1 installation

Installation of required RPMs:

  1. Automatic  Process
All necessary prerequisites will be performed automatically. It is probably worth doing a full update as well. The simple "yum update" command will set the oracle recommended values to sysctl.conf and limit.conf files.
# yum update

  1. Manual Process
Add the following lines to the "/etc/sysctl.conf" file.

kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.hostname = localhost.localdomain
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
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

Add the following lines to the "/etc/security/limits.conf" file.

oracle   soft   nofile    1024
oracle   hard   nofile    65536
oracle   soft   nproc    2047
oracle   hard   nproc    16384
oracle   soft   stack    10240
oracle   hard   stack    32768
