OpenACS 5.9.0 will install with Oracle 9i but has not been extensively tested so may still have bugs or tuning issues. See Andrew Piskorski's Oracle 9i notes for guidance. -

This installation guide attempts to present all of the information necessary to complete an OpenACS installation. We try hard to make all of the steps possible in one pass, rather than having a step which amounts to "go away and develop a profound understanding of software X and then come back and, in 99% of all cases, type these two lines." The exception to our rule is Oracle production systems. This page describes a set of steps to get a working Oracle development server, but it is unsuitable for production systems. If you will be using OpenACS on Oracle in a production environment, you will experience many problems unless you develop a basic understanding of Oracle which is outside the scope of this document.

This document assumes that you'll be installing Oracle on the same box as AOLserver. For more details on a remote Oracle installation, see Daryl Biberdorf's document. -

Production Oracle systems should run on certified platforms. Follow the metalink note 223718.1to find certified platforms. If you don't have metalink access, take a look at the Oracle on Linux FAQ: Which Linux Distributions Are Directly Supported By Oracle?. In summary, free and inexpensive Linux distributions are not certified. -

You can download the Oracle software from the Oracle Downloads page. -

Each Oracle release comes with extensive and usually quite well-written documentation. Your first step should be to thoroughly read the release notes for your operating system and your Oracle version. Find the docs - here:

It is generally useful to run a particular Oracle version with its latest patchset. At the time of writing these were 8.1.7.4 and 9.2.0.5, both of which are considered to be very stable. -
- -+
To be able to download a patchset, you need a (to-pay-for) account on Metalink. You may find the appropriate patchset by following Andrew's suggestion. -
- -Oracle is very well-documented software, the online documentation comes with printable PDFs and full-text search. Altogether there is more than 20.000 pages of documentation, so do not expect to understand Oracle within in a few hours. The best starting pointing into Oracle is the Concepts book. Here's the 8i version and the 9.2 version. -
- - -+
To give you an idea of how configurable Oracle is and how much thought you may need to put into buying the proper hardware and creating a sane setup, you should thoroughly read Cary Millsap's Configuring Oracle Server for VLDB and the Optimal Flexible Architecture standard. -
- - -+
Throughout these instructions, we will refer to a number of configurable settings and advise certain defaults. With the exception of passwords, we advise you to follow these defaults unless you know what you are doing. Subsequent documents will expect that you used the defaults, so a change made here will necessitate further changes later. For a guide to the defaults, please see the section called “Defaults”. -

In order for OpenACS to work properly you need to set the environment appropriately. -

perform several manual, administrative tasks before we can launch
it. You must perform all of these steps as the

Oracle has an internal representation for storing the data based on
the number of seconds elapsed since some date. However, for the
purposes of inputing dates into Oracle and getting them back out,
Oracle needs to be told to use a specific date format. By default, it
uses an Oracle-specific format which isn't copacetic. You want
Oracle to use the ANSI-compliant date format which is of form
'YYYY-MM-DD'.
-
+
To fix this, you should include the following line in
$ORACLE_HOME/dbs/initSID.ora
or for the default case,
$ORACLE_HOME/dbs/initora8.ora
-
-nls_date_format = "YYYY-MM-DD"- -
+
+nls_date_format = "YYYY-MM-DD"
You test whether this solved the problem by firing up
sqlplus and typing:
-
-SQL> select sysdate from dual;- -
+
+SQL> select sysdate from dual;
You should see back a date like
2000-06-02. If some of the date is
chopped off, i.e. like 2000-06-0,
everything is still fine. The problem here is that
sqlplus is simply truncating the
output. You can fix this by typing:
-
+SQL> column sysdate format a15 -SQL> select sysdate from dual;- -+SQL> select sysdate from dual;
If the date does not conform to this format, double-check that you included the necessary line in the init scripts. If it still isn't working, make sure that you have restarted the database since adding the line: -

If you're sure that you have restarted the database since adding the line, check your initialization scripts. Make sure that the following line is not included: -

Setting this environment variable will override the date
setting. Either delete this line and login again or add the following
entry to your login scripts after the
nls_lang line:

Log back in again. If adding the
nls_date_format line doesn't
help, you can ask for advice in our OpenACS forums.
