Sakai's Architecture 
Sakai is a Java-based, extensible, service-oriented learning platform that provides a variety of capabilities supporting teaching and learning, portfolios, research, and ad-hoc project collaboration. It is typically deployed and scaled by running multiple instances of Apache Tomcat in a clustered environment, each deploying a copy of Sakai. Sakai integrates with a variety of external authentication services including CAS, Kerberos, LDAP, Shibboleth and WebAuth. A single database, usually MySQL or Oracle, provides a transactional store of information while file storage is delegated to NAS or SAN solutions. In most production settings, Sakai relies on a back-end student information system (SIS) to provide it with student and course information, which Sakai  consults via provider APIs

Source Code and Maintenance
Sakai currently uses Subversion for source control.  Current development work targets Sakai trunk; maintenance branches provide bug fixes and minor feature enhancements for released versions of the product.  

10.0 tag: svn co https://source.sakaiproject.org/svn/sakai/tags/sakai-10.0 10.0

System Requirements
Sakai is Java-based and will run on a wide variety of platforms. That said, a number of supporting technologies are required to run Sakai in a production setting.

Java SE 7 (also compatible with Java SE 6)
Sakai 10 has been tested most thoroughly with Oracle's Java 7. It also should be binary compatible with Java 6, aka Java 1.6 . Requires JDK 6 to build "all code".  Likely support for JDK 8. Certain files, such as *.jsp and *.jws, require compilation so downloading and attempting to use only the run time environment (e.g. JRE 7.0) will not suffice.

Apache Tomcat 7
Although Tomcat is not the only available servlet container, it is highly recommended for Sakai. Sakai QA is conducted on Tomcat 7 and the documentation assumes Tomcat use.

Apache Maven 3.0.5
Maven 3 is the build tool used to deploy the source code and is therefore not necessary if you only plan to install the Sakai Demo with the default configuration. For production deployments it is an essential supporting technology.

Sakai production installations typically run MySql 5.5 or later. Oracle is the next most popular choice. There are known installations of Sakai on Oracle 10g, 11g, and 12c. It should be noted that Sakai is not limited to these database choices and integration with other RDBMS systems is not difficult. Sakai utilizes HSQLDB as its "out of the box" database, requiring no special installation steps to set up but this database is not recommended for production installations.

Database Drivers
For MySQL 5.5 we recommend mysql-connector-java-5.1.13+ with query caching enabled.
Regardless of the version of Oracle in use, we recommend using a recent Oracle 11g driver (See SAK-11960).

Introduction for New Developers
The best introduction for new developers is found in a wiki space called the Programmer's Cafe. A number of experienced Sakai developers have banded together there to produce guides and tutorial materials for those who wish to start hacking on Sakai.

Issue Tracking
Bug reports and feature requests may be created and monitored through Jira.

Older Releases
With the advent of the Sakai 10 series, official Community support for Sakai 2.8 has ceased. Organizations running Sakai 2.8 (or earlier versions) are strongly encouraged to upgrade to the latest versions of Sakai 2.9 or Sakai 10 in order to take advantage of continued maintenance support.
