Setting up Multi-Process ArcViz

In Cloudera Manager, under the Clusters tab, select the Configuration interface.

Under the Filters menu, expand Scope, and then select Arcadia Visualization Server.

In the main area of the interface, in the search box, enter the text worker and start the search.

Note that the search results return our configuration parameters:

• Number of Arcviz Workers

  This is the number of concurrent Arcviz processes; our recommended and default setting is 3.

• Starting port for Arcviz Workers

  The port where the first worker 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 Arcadia Visualization Server run correctly.

• Logging port for Arcviz Workers

  This port runs the logging jobs for the worker processes.

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

In Cloudera Manager, under the Clusters tab, select the Configuration interface.

Under the Filters menu, expand Scope, and then select Arcadia Visualization Server.

In the main area of the interface, in the search box, enter the text arcvoz_force_single_proc and start the search.

Note that the search results return a single configuration parameter:

• Force Arcviz legacy single process mode

  Select this option to disable multi-processing.
