Enterprise Analytics Processes

  • concept
    +
    Enterprise Analytics creates a number of different processes on each node. Enterprise Analytics creates processes from a set of binaries that get installed by the product installer.

    The tables on this page list out all of the Enterprise Analytics processes. It’s important that you allow each of these processes to run and access files on the nodes. Otherwise, Enterprise Analytics does not function properly. Depending on your security environment, you may need to explicitly approve these processes and their binary directories in your security policy.
