System Requirements



Client Requirements



Any client operating system supporting:

  • Microsoft Internet Explorer IE7, IE8, IE9, IE10, IE11

  • Firefox 3.6+

  • Safari 4+

  • Chrome 9+


Browser Configuration:  The default settings for most browsers is sufficient to use Unanet.  In particular though, the browsers must be configure to allow cookies and javascript.  IE8 displays best when run with the Compatibility Mode disabled.

Popup Blockers:  will need to be configured to allow popups from your Unanet site.

Server Requirements


Web Servers

The web servers embedded in JRun or Tomcat will run the Unanet application, however, you can also use an external web server such as:

  • Microsoft IIS 5 or higher

  • Apache 1.3.x or higher



  • Java 1.6,  Java 1.7, Java 1.8


Note: Beginning with Unanet version 9.6, we no longer support Java 1.5.

Note: Java 1.7 is not compatible with JRun

Servlet Engines

  • Tomcat 6.0.20 --> 6.0.28,  7.0, 8.0

Note: There is a known issue with Tomcat 6.0.29+.  Do not attempt to run Unanet with a version of Tomcat 6 higher than 6.0.28 or below 6.0.20.  This issue has been addressed in Tomcat 7.

  • JRun 4   (Unanet no longer recommends the use of this product and will officially drop support beginning with Unanet v10.0)


Note: In summer of 2007, Adobe announced plans to discontinue new feature development for the Adobe® JRun™ software.
(see for more information).

JRun requires updater 7   --  see for more information

Note: Java 1.7 is not compatible with JRun

Operating System

  • Windows 2003, 2003-R2, 2008, 2008-R2, 2012, 2012 R2

  • Unix / Linux

Note: Supported on 32 & 64 bit operating systems


  • Oracle 10g, 11gR1, 11gR2, 12c

Note: Beginning with Unanet version 9.6, we no longer support Oracle 9.

  • Microsoft SQL Server  2005, 2008, 2012, 2014 (Enterprise, Standard, Workgroup and Express Editions)


Note: Beginning with Unanet version 9.4, we no longer support SQL Server 2000.

Note: JDBC drivers are included.

Note: The Express version has a number of limitations which may prevent its use in your environment, such as:

  • Constrained to a single CPU (in 2012, this limitation has been changed to "the lesser of one socket or four cores" - thus, multi-threading is possible)

  • A maximum of 1GB RAM Buffer Pool (same in 2008 & 2012)

  • A maximum 4 GB database size (raised to 10GB in SQL 2008 & 2012)

  • Further, it may lack certain enterprise level utilities that may be of interest for database maintenance, tuning and possible future SQL Server version migration needs.  Further information my be found at:
