2. Starting off

2.1 Prerequisites

At least 800M free on your hard disk. Type:

bash$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda2             5.3G  3.6G  1.4G  72% /

and read the field Avail.


The steps we are going to describe allow to have Oracle 8i, version 8.1.7 running on:

In any case, never underestimate Oracle's system prerequisites.

2.2 Linux setup


We focus on a Linux RedHat 7.2 distribution, since we had problems with it and we wanted to use it. The steps we are going to describe should work on any Red Hat 7.2 based Linux distribution.

Distribution Setup

We assume you have your Linux RedHat 7.2 box installed and working in a reasonable way for you. In any case, 'base' packages, X Windows (the installation routine is a Java GUI) and the development tools regardless of whether you intend doing any coding or not is what you need.

Setting users and groups

Login as root:

$ su - root

and type whatever password you decided root must have.

Create groups:

bash# groupadd oinstall
bash# groupadd dba
bash# groupadd oper

Create oracle user and set its password:

bash# useradd oracle -g oinstall -G dba,oper
bash# passwd oracle (to change password)

Installing the right Java Virtual Machine

The only Java Virtual Machine compatible with Oracle 8i, version 8.1.7, is:
Do not think: "newer versions will be less buggy", as the installer probably won't work. And don't think.

Once downloaded it, move it:

bash# mv jdk118_v3-glibc-2.1.3.tar.bz2 /usr/local

untar it:

bash# tar xvIf jdk118_v3-glibc-2.1.3.tar.bz2

and create a symbolic link to the folder the command here above has just created:

bash# ln -s /usr/local/jdk118_v3 /usr/local/java

Kernel parameters

Oracle documentation suggests that you make changes to the Linux kernel so you can get more shared memory. If you decide to follow that way, keep the instructions in the Oracle documentation and the Linux Kernel HOWTO at hand to build your new kernel.

In fact, the required changes can be made by setting some parameter in a suitable initialization file. Just follow some steps:

In any case, if you want just to start playing with Oracle 8i, version 8.1.7, Linux RedHat 7.2 default settings can work fine, and you do not need to set any kernel parameter, as just described.

Setting up some libraries

There may be some compatibility problems between Oracle 8i and gcc versions >= 2.1. If you experience them, download these rpms:


install them, as usual, by:

$ rpm -Uvh compat-egcs-6.2- compat-glibc-6.2- compat-libs-6.2-3.i386.rpm
and, finally set a symbolic link because there is a small installation bug in one of the packages just installed:
bash# ln -s /bin/id /usr/bin/id

Final step

Reboot your machine and keep reading...
