Oracle Installation Prerequisites
Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. so I prefer Automatic Setup.
Automatic Setup
We can follow the instructions at http://public-yum.oracle.com to set up the yum repository for OL, then perform the following command.
| # yum install oracle-rdbms-server-12cR2-preinstall -y |
All necessary prerequisites will be performed automatically.
It is probably worth doing a full update as well, but this is not strictly speaking necessary.
| # yum update |
Create new groups and users.
I have group oinstall, dba and oper and oracle user before then, I used groupmod and usermod commands, if you don’t have them before You have to use groupadd and useradd command
| groupmod -g 201 oinstall groupmod -g 202 dba groupmod -g 203 oper groupadd -g 204 asmadmin groupadd -g 206 asmdba groupadd -g 205 asmoperusermod -u 202 -g oinstall -G dba,asmdba,oper oracle passwd oracle |
Create the directories in which the Oracle software will be installed.
| mkdir -p /oracle/product/12.2.0/db chown -R oracle:oinstall /oracle chmod -R 775 /oracle |
Login as root and issue the following command.
| xhost +192.168.75.130 |
Log in as the oracle user and add the following lines at the end of the “.bash_profile” file.
| # Oracle Settings TMP=/tmp; export TMP TMPDIR=$TMP; export TMPDIRORACLE_HOSTNAME=dblabT2.localdomain; export ORACLE_HOSTNAME ORACLE_UNQNAME=DB12C; export ORACLE_UNQNAME ORACLE_BASE=/oracle; export ORACLE_BASE ORACLE_HOME=$ORACLE_BASE/product/12.2.0/db; export ORACLE_HOME ORACLE_SID=DB12C; export ORACLE_SIDPATH=/usr/sbin:$PATH; export PATH PATH=$ORACLE_HOME/bin:$PATH; export PATHLD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH |
