With this HOWTO, and a little luck, you will be able to get “Oracle 8i Enterprise Edition for Linux” installed, create a database and connect to it from a remote machine. The main focus of this guide is RedHat Linux 6.0 and Oracle 8.1.5, although it should work well for other recent distributions and more stable versions of Oracle.

## 1. Introduction

## 1.1. What’s in here?

Linux is well known for being difficult and, generally, user hostile. Being a bit of a Unix fan I’m not sure whether I agree with that or not.

Prerequisites

Oracle 9i is the result of merging almost their entire product line into two products. To say that 9i is the database is a little misleading, but this is what you need if you want to keep current with your Oracle database.

There are a few things that you need to be aware of before embarking on the installation of Oracle 9i. First are it’s hardware requirements. They’re huge, much more than 8i which itself was large.

In all honesty, I’ve not managed to get Oracle working properly yet. When I upgraded my RedHat 7 machine to 8 it still worked, when I installed it from scratch it didn’t. This clearly shows that it’s possible to get Oracle 8i working, but I can’t say how!

For those that are interested, I found that it was easy to get the installer to complete, but I get the infamous “end of communication channel” error when trying to start an instance.

You tend to find two things relating to programming languages on the Internet. The first is a long list of all the languages, often with links to a representative web site. The second category are the “representative” web sites, detailed descriptions of a particular language.

I hope to make this part of ZX81.org.uk to be the middle-ground. I won’t cover every language ever designed and nor will I cover them in vast amounts of detail. Instead I’ll look at each languages main features, advantages and flaws.

I have recently installed Oracle 8i R3 (8.1.7) on my Celeron 466 machine. I found the installation to be very straight-forward compared with both 8.1.5 and the experiences of many people.

My machine is well below the specification that would be required to do real work on, especially if you have a number of developers. It does work, albeit rather slowly. Creating my initial database, for example, took around eight hours.

Introduction

The subject at hand is really much wider than just Redhat 7.x, especially as more recent distributions are following Redhats lead and are now including glibc 2.2 also. I have no reason to believe that this process will not work with newer versions of SuSE, Debian, etc.

The other point to note is that I have not tried the procedure outlined here. I have migrated my box from Debian 2.2 to RedHat 7.2 and can testify that Oracle still works, but I have not actually performed an installation. I have, however, recieved a good number of emails confirming that it works, so don’t worry!

Working eight hours a day with a product, you notice not only bugs, but other strange bits and pieces too. This is the page for them.

• One mis-spelling of ‘Oracle’ looks remarkably like ‘Roach.’ Surely not just a coincidence.
• Mis-typing ‘ORACLE_SID’ often looks like ‘ORACLE_SOD’ which is only one word short of what you usually think when you’ve done this.

Fair’s fair, any application the size and complexity of Oracle Applications will have some bugs. But applications seems to do far better than most.

This section refers to the server size of Applications Comedy Errors. There’s another page for the client side.

• To install a new application module, it seems that you have to add the original version you have plus all patches. Not just for your new module, but for all of them. (People that implement Application’s are not expected to make mistakes.)
• The recommended sizes for your database extents are useful. However, if you follow the advice, some parts of the system won’t actually install.
• Oracle helpfully supply a program that goes through the thousands of files that it installs and checks that they’re the right ones. We’ve found at least a dozen files that it claims shouldn’t be there but in fact should be.
• After applying a patch, the shell script that starts the Concurrent Managers just vanished.
• One of the bugs that we found was because Oracle had ‘forgotten’ to port a number of forms from one environment to the one we were using. The word ‘forgotten,’ despite being inverted commas, is the actual word used by Oracle support.

Welcome to the Oracle Comedy Errors Page!

This page is dedicated to all those frustrating hours that you have to spend fiddling about with Oracle just to get it working as it says it does on the box.

These are just things that have happened to me and the projects that I have been involved in. To make a really complete Oracle Comedy Errors Page we need your input.

For those that have already contributed, there is always this page. It also catalogues the projects and Oracle software that I’ve used to build up this list.

Oracle, the company, was founded back in the late seventies as a company that produced an SQL database. Its entire reputation has been built on this product and it is, therefore, no surprise that it is very good.

That’s not to say that there have been no problems…

• To perform dodgy ‘system’ operations on a database, you need access to a user called ‘internal.’ In theory, you need to be in the UNIX ‘dba’ group to be able to connect. That is unless you belong to rather a lot of groups, in which case it doesn’t seem to work. (We’ve not actually called this through, so there may be a simple explanation.) (7.1)
• When creating a new database, you have to run a file called ‘catalog.sql’ to finish the job. At the end of this file is the following message: ‘THIS IS THE END OF THIS FILE – IF I AM NOT HERE THEN RCS HAS TRUNCATED FILE‘ (7.3)
• I’m not entirely sure that this counts, but an installation program that requires more resources than that product that it’s installing demands at least an honorable mention. (8i)
