Setting up Multi-Process ArcViz on Ambari Stacks

Arcadia Enterprise enables the multi-process Arcadia Visualization Server by default on Ambari.

Enable or Change the Multi-Process Configuration

Multi-process Arcadia Visualization Server is enabled by default. Follow these steps to review or change the multi-process configuration of ArcViz:

  1. Select Arcadia Enterprise entry from the left navigation menu.
  2. Click the Configs tab near the top of the interface.

  3. Under Arcadia Visualization Server, note the following configuration parameters:

    Force Arcviz legacy single process mode
    This option enables or disables multi-process mode. To continue to run Arcadia Visualization Server in multi-process mode, make sure this option is not selected.
    Metadata Storage Type
    Specify where to store metadata. Note that if you select SQLite, Arcadia Visualization Server will run in legacy single process mode. You can select one of the other options, depending on your system architecture and database. If you choose MySQL, Oracle, or PostgreSQL, the database must be already in place, otherwise specify the database information.
    Logging port for Arcviz Processes
    This port runs the logging jobs for the processes.
    Number of Arcviz Processes
    This is the number of concurrent Arcviz processes; our recommended and default setting is 3.
    Starting port for Arcviz Processes
    The port where the first process runs, 30141 by default. Other processes run on contiguous and sequentially-numbered servers, such as 30142 and 30143. We chose this range because it is not used by standard processes. In the highly unlikely situation where custom internal processes already run in the specified range of ports, you should assign a new starting port for this parameter and subsequent ports, so that Arcadia Visualization Server runs correctly.

    Note that the Arcadia Visualization Server Web entry point is on port 38888.
