2 Planning Your Convergence Installation

This chapter provides information about planning your Oracle Communications Convergence installation.

Planning Considerations

Planning your Convergence installation involves:

  • Planning your system deployment. See the discussion about the Convergence deployment architecture in Convergence System Administrator's Guide for more information.

  • Determining the services you plan to deliver in Convergence.

    For each service, review the planning guidelines for the corresponding application. For example, if you plan to deploy Convergence with the mail, calendar, and address book services, review the planning guidelines for Oracle Communications Messaging Server, Oracle Communications Calendar Server, and Oracle Communications Contacts Server.


    Instant Messaging service is available only in GlassFish deployments.
  • Determining the scale of your implementation. To determine the scale, consider the number of users you intend to serve and the number of services you intend to deliver.

  • Designing your network around the services you plan to deliver.

Some Convergence features are limited by third-party applications. Consider the following limitations when planning your Convergence installation, and determine how to inform your users.

  • HTML5 support:

    Some Convergence features are delivered over HTML5. Most browsers support HTML5 by default, but some browsers need to be configured to support HTML5. Users accessing Convergence with Internet Explorer 10 or later must do the following:

    • Configure their browser not to run Convergence in Compatibility View.

    • Not include the Convergence URL in the Websites you've added to Compatibility View list.

    • Disable Display intranet sites in Compatibility View if Convergence is deployed to an intranet site.

    See the discussion about compatibility view settings in the Internet Explorer online Help for more information.

  • Secure/Multipurpose Internet Mail Extension (S/MIME) support:

    You can configure Convergence to send encrypted or digitally signed email messages. Convergence uses S/MIME to sign and encrypt email. S/MIME features work only if email is sent using Internet Explorer or Firefox on a Windows computer.

  • Web Real-Time Communication (WebRTC) support:

    You can enhance Convergence with WebRTC features such as voice and video calling and screen sharing. WebRTC features are supported as follows:

    • A screen sharing session can be initiated only from a Google Chrome browser.

    • Mozilla Firefox users cannot initiate screen sharing but can receive screen-sharing requests. Once a screen sharing session has begun, a Firefox user has the same capabilities as a Chrome user.

    • Chrome version 67 must be launched manually from a command line with the enable-usermedia-screen-capturing flag to initiate a screen sharing session. For example, from a Windows command line, enter:

      start chrome --enable-usermedia-screen-capturing
    • Microsoft Internet Explorer, Microsoft Edge, and Apple Safari do not support any WebRTC features.

    • You can deliver WebRTC features in Convergence using either WIT Software or Oracle WebRTC Session Controller. See the discussion about configuring WebRTC services in Convergence in Convergence System Administrator's Guide for more information.

  • Tablet support:

    Convergence can be accessed on an Apple iPad (Safari browser) or a Samsung Galaxy Tab (Chrome browser). When Convergence is accessed from a supported tablet, the following subset of Convergence services is available: messaging, calendar, and address book.

Deployment Recommendations

Oracle recommends that you place the Messaging Server Webmail Server on the same host as Convergence, which allows easy horizontal scalability and easy service growth. Other components such as the message store and message transfer agent (MTA), Calendar Server, and Instant Messaging Server can be located on other hosts.

Default Paths and File Names

Table 2-1 lists the directories that are created when you install Convergence. The same directories are created for the Solaris and Linux operating systems.
