]> High level information: What is OpenACS? The place to start if you want a soft, high level introduction to OpenACS &release-notes; Help to the folks keeping an OpenACS installation up and running. This document is a guide to installing OpenACS). It is targeted for first time users who may not be familiar with Oracle and AOLServer, but who are familiar with UNIX - with an emphasis on Linux. However, for the purposes of running the OpenACS, Linux is not substantially different from other UNIX systems, such as Solaris or HP-UX. Assuming you have a computer with a network connection, before starting installation of OpenACS please refer to the following: If it's a PC and you're going to use Linux, then read everything. If it's a UNIX box, skip the Linux chapter and read everything else. If it's a Windows box, read How to install OpenACS on Windows instead. If you already have Oracle up and running, then skip to the AOLserver 3.x chapter and read from there. If you are interested in learning more about OpenACS first, then please read Chapter Three: Scalable Systems for Online Communities from Philip & Alex's Guide to Web Publishing, and this document on Using the ArsDigita Community System. &getstarted; &requirements; &redhat; &oracle; &aolserver; &acs; &acc-tests; &credits; This walks you through an OpenACS installation under Windows. &win2k; This is the place to look if you want to extend OpenACS and build on top of what's already here.

The OpenACS 4 Core, which comprises all the other packages that ship with the kernel and are most frequently needed by users, such as templating, bboard, and user registration/management. The packages tend to be developed and distributed with the kernel. OpenACS 4 Application packages, which typically provide user-level web services built on top of the Kernel and Core. Such packages include those built by ArsDigita as well as external contributors. Application packages are developed separately from the Kernel, and are typically released independently of it. This document provides a high level overview of the kernel package. Documentation for the other packages can be found elsewhere. &objects-req; &objects-design; &permissions-req; &permissions-design; &groups-req; &groups-design; &subsites-req; &subsites-design; &apm-req; &apm-design; &security-req; &security-design; &security-notes; &rp-req; &rp-design; &db-api; &tcl-doc; &bootstrap-acs;
