16.2 GroupWise WebAccess System Requirements

16.2.1 Hardware and Operating System Requirements

  • x86-64 or x86-32 processor

  • Any of the following server operating systems for the WebAccess Application:

    • Novell Open Enterprise Server (OES) 11 or Novell Open Enterprise Server (OES) 2015, plus the latest Support Pack

    • SUSE Linux Enterprise Server (SLES) 11 or SUSE Linux Enterprise Server (SLES) 12 plus the latest support pack

      IMPORTANT:SLES 12 is only supported up to SP3. SP4 upgrades Tomcat to version 9 which doesn’t work with WebAccess.

      NOTE:On Linux, the X Window System and Open Motif are required by the GUI GroupWise agent server consoles for the Post Office Agent, the Message Transfer Agent, and the Internet Agent.

      By default, the GroupWise Linux agents run as services without user interfaces. Starting and stopping the agents when they are running with a user interface is not supported in the GroupWise Administration console.

    • Windows Server 2012 R2 or Windows Server 2016, plus the latest Service Pack

  • Adequate server memory as required by the operating system

  • Adequate server disk space:

    • Approximately 525 MB (shared with the Calendar Publishing Host Application and the Monitor Application when they are installed on the same web server; varies by platform)

16.2.2 Web Server Requirements

The web server that is supported for your operating system:

  • x86-64 or x86-32 processor

    • Tomcat 6

    • ModProxy Module

    • OES11 / OES 2015 / SLES 11: IBM Java 6 Runtime Environment (JRE) or later

      SLES 12: OpenJDK 7

    A Linux repository should be available when you run the GroupWise Installation Wizard. Apache, Tomcat, the JRE or JDK, and the ModProxy Module are automatically installed from the Linux repository if they are not already present on the Linux server.

    If no Linux repository is available during the GroupWise installation, you are prompted to manually install these required components from the Linux media, and then restart the GroupWise installation.

  • Windows Server 2012 R2 or Windows Server 2016

    Microsoft Internet Information Server (IIS) 7 or later plus:

    • Tomcat 6

      Tomcat 6.0.24, Oracle JRE 8, and Jakarta Connector 1.2 are automatically installed along with the GroupWise software if they are not already present on the Windows server.

    • ISAPI support

      ISAPI support is no longer installed by default when you install Windows Server 2008 R2 or later and Internet Information Services (IIS). If ISAPI support was not manually selected when IIS was installed, you can add it after the fact. See
