Install the software separately

In this post I’ll install the Oracle database software, without having the Oracle Universal Installer  (OUI) creating a database.
In a future post, I’ll create a database with DBCA (DataBase Configuration Assistant), and also manually (with the CREATE DATABASE statement).

Check that the oracle account exists, and is in the groups oinstall and dba:
id oracle
uid=500(oracle) gid=500(oracle) groups=500(oracle)

In my case it exists, but it's not yet in the groups dba and oinstall.

Create the groups:
/usr/sbin/groupadd oinstall
/usr/sbin/groupadd -g 502 dba
/usr/sbin/groupadd -g 503 oper

Assign the Oracle account to the dba and oracle groups
/usr/sbin/usermod -g oinstall -G dba  oracle [, oper]

(If the Oracle account didn't exist yet, run this instead: /usr/sbin/useradd -u 502 -g oinstall -G dba,[oper] oracle)

Create the ORACLE_BASE directory (logged on as root):
mkdir -p /u01/app/oracle
chown -R oracle:oinstall /u01/app/oracle
chmod -R 775 /u01/app/oracle

Create the Oracle inventory location (logged on as root)
mkdir -p /u01/app/oraInventory
chown -R oracle:oinstall /u01/app/oraInventory
chmod -R 775 /u01/app/oraInventory

Add The following lines to .bash_profile:
umask 022
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export PATH=$ORACLE_HOME/bin:$PATH
export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib32:$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export LIBPATH=$ORACLE_HOME/lib32:$ORACLE_HOME/lib:$LIBPATH

Log on as the Oracle user.
If you're already logged on, run: . $HOME/.bash_profile
I didn't bother changing kernel parameters / setting resource limits. In theory, the installer will come up with a fixup script to alter this.

Copy over the first 2 11gR2 installation CD's  to $HOME/11gR2
(you can download the correct version immediately from Oracle support, no need anymore to first install the base release and apply patch sets afterwards).Unzip both zip files:

cd $HOME/11gR2
unzip p10404530_112030_Linux-x86-64_1of7.zipunzip p10404530_112030_Linux-x86-64_2of7.zip
rm *.zip
cd database

Unset the ORACLE_HOME: unset ORACLE_HOME
Start the Oracle Universal Installer: ./runInstaller

 

Choose Skip Software Updates:

Choose Install Database Software Only:

Choose Single Instance Database Installation:

Add all the languages in the following screen:

Choose Enterprise Edition (or the edition for which you have a licence...):

The ORACLE_BASE environment variable was set => the OUI has filled out the Oracle Base automatically, and derived an OFA compliant directory for the ORACLE_HOME. Accept both values.

The installer will perform some prerequisite checks, and will show you the result:

Click on Fix and Check Again. Oracle will generate a fix up script (since 11g):

Run the generated script as root: /tmp/CVU_11.2.0.0.2_oracle/runfixup.sh
Click Check Again => No errors are displayed. Click Next to go to the following screen, and click on Install:

Execute the following scripts as root, and afterwards press OK:

The installation will now start.

In next posts, I’ll create the database manually (create database command) and using DBCA.
