The Reciprocal Net site software is a web application written primarily in Java, designed to be installed on an existing web server running the GNU/Linux operating system.� It is distributed in Red Hat Package Manager (RPM) format.� An online Yellow Dog Updater Modified (YUM) repository is available.
� System
o minimum: any modern Intel-based desktop PC.
o recommended: server-class machine with an uninterruptable power supply for high availability.
� Memory
o recommended: at least 512 MB RAM
� Disk
o minimum: at least 5 GB free hard drive space.
o recommended: redundant disk array for high availability
� Processor
o minimum: Pentium 4-class 32-bit capable processor
o optional: 64-bit-capable processor (e.g. EM64T, AMD64).� However, this release of Reciprocal Net site software does not take advantage of 64-bit-capable processors.
Sites that are particularly concerned about availability and reliability are advised to select server-class hardware with redundant disk arrays.
Several distributions of the GNU/Linux operating system have been tested extensively with this release of the Reciprocal Net site software and are known to be compatible:
� Red Hat Enterprise Linux 5, i386 edition (including release 5.1)
� CentOS 5, i386 edition (including release 5.1)
� Scientific Linux 5, i386 edition
� Fedora Core 6, i386 edition
� Fedora Core 7, i386 edition
� Fedora Core 8, i386 edition
Use of other GNU/Linux distributions and even other operating systems may be possible but cannot be supported by the Reciprocal Net project.� Note that only the i386 editions of GNU/Linux operating systems are supported at this time.� These are able to run on both 32-bit-capable and 64-bit-capable Intel-compatible processors.� Although some sites have reported success running Reciprocal Net sites on x86_64 editions of the GNU/Linux operating system, such configurations have not been tested and thus are not recommended.
Older GNU/Linux distributions are no longer supported by the Reciprocal Net project.�� In particular, use of Red Hat Linux 8 is discouraged because its product support ceased in year 2003, and use of Fedora Core 1 is discouraged because its product support ceased in year 2005.� Existing Reciprocal Net sites that may be running these obsolete operating systems are urged to upgrade.
� A web server daemon.� Apache Httpd 2.2 from the Apache Software Foundation has been tested extensively and is supported.
� A servlet container daemon or J2EE daemon.� Apache Tomcat 5.5 from the Apache Software Foundation has been tested extensively and is supported.� Note that some software packages are capable of fulfilling both the web server requirement and the servlet container requirement.
� A Java virtual machine (VM) compatible with J2SE specification 1.5.0 or higher.� JDK 6 from Sun Microsystems has been tested extensively and is supported.
