Purpose
Questions and Answers
 What is Enterprise Manager(EM) for Oracle Big Data Appliance (BDA)?
 Where can I find EM for BDA Documentation?
 Are the Plug-ins required for OEM Management downloaded and installed on the BDA servers by default?
 What are the default ports used by EM?
 What about the port EM 3872? What is that?
 Can EM agents on the BDA be installed and configured without meeting the prerequisite for Enterprise Manager (EM) platform version 12.1.0.2?  In other words can someone use Enterprise Manager platform version 12.1.0.1?
 Can the Management Agents for the Big Data Appliance Plug-in be installed as part of the Big Data Appliance Mammoth software installation?
 If Management Agents are not installed as part of Big Data Appliance software installation, you can subsequently run the installation program (Mammoth utility) to perform this task?
 Can you also use the Mammoth utility to replace existing Management Agents?
 If an error is encountered during Big Data Discovery are there any log files which should be collected?
 What could be the reason that "Power Supply Sensor Status - Power  supply sensor(s) at level -CRITICAL" can not be cleared in OEM even if the ILOM snapshot shows no problem?
 What version of the BDA Plugin does Enterprise Manager(EM) Plug-in on the BDA 3.0.* require?
 Trying to create a collective standard metric with the 3 BDA IB switches (2 Gateway and 1 Spine) monitored together does not work but monitoring each switch independently reports correctly.    Could this be related to error in the repository collection?
 Is it possible to monitor non-BDA Hadoop clusters from OEM 12c V12.1.0.4 ?
 Is it recommended to use the same OMS monitoring Oracle DB and other targets for BDA, or to have a separate  OMS for BDA?
 Is it possible to  create an ILOM account specifically for OEM access with reduced authority and point the plugin to that instead of root?
 What role(s) would the credentials actually require for OEM to function properly? The goal here is to  reduce authority to the minimum required if possible.
 In BDA V4.4 does EM discover ILOMS for NoSQL?
 In BDA V4.4/with the 12.1.0.4 plugin is it possible to monitor the hardware of BDA NoSQL clusters?
 When deploying the 12.1.0.4 plugin with bdacli an "https" error is raised.  What does that mean?
 Does BDA V4.4 suport the 13.1 EM plugin?
 If I tried to install the 13.1 EM plugin on BDA 4.4 what would I do upon failure?
 What Hadoop targets are monitored by the OEM plugin?
 Are Big Data SQL targets monitored by the OEM plugin?
 Do EM agents always use client hostname?
 What options are there if the 'oracle' user does not have privileges to run sudo and needs to deploy the OEM 13.2 plug-in on the BDA?
 What version of the plugin supports TLS?
 What are the best practice recommendations regarding PDUs being accessible on the network and PDU monitoring?
