======================================================
SPECvirt :sup:`®` Datacenter 2021 Technical Support
======================================================

Clients
============

For problems deploying clients, check the following.

1. Ensure that the svdc-template's and svdc-director's virtual NIC has assigned the correct MAC address. Check the svdc-template's ``eth0`` vNIC settings to ensure that the MAC prefix (the first three octets) assigned to the vNIC matches the value for ``MACAddressPrefix`` that you set in Control.config for the testbed network. The default for svdc-template is ``42:44:49:00:00:00``. The default for svdc-director is ``42:44:49:00:00:02``.
#. Ensure that the svdc-director's virtual NIC has assigned the correct IP address. Check that the svdc-director's IP address uses the value of  ``IPAddressPrefix`` and ``0.2``. The default IP address for the svdc-director is ``172.23.0.2``.
#. Use ping to make sure that the svdc-director can contact the management server.

Submissions
============

If you encounter problems during the collection of the support tarball archive at the end of a measurement, you can rerun ``${virtVendor}/collectSupport.sh`` manually. 
The support archive is valid as long as you haven't made changes to the testbed. 


HammerDB
==============

HammerDB creation during prepSUT.sh takes a long time and appears to hang. CPU utilization on the svdc-director is idle, and the console output reads::

 ...
  ALL VIRTUAL USERS COMPLETE
 hammerdb>DB load successful. Creating DB backup. **Note, this takes several minutes (or more).
 Please be patient...

This pause occurs as the harness backs up the HammerDB database on the svdc-director and could take several hours.

To monitor active HammerDB transactions during a measurement:

 1. Get the "jobid" from http://svdc-txxx-happ:8080/jobs
 #. Enter the "jobid" at http://svdc-txxx-happ:8080/jobs?jobid=[jobid] and refresh browser to see updates

BigBench
===========

To access the BigBench web console and monitor transaction job history::

  http://svdc-txxx-bbnn:19888/jobhistory/app - shows history of 38 jobs completed during initial load as well as all past jobs

  http://svdc-txxx-bbnn:8088/cluster/apps - monitor active BigBench jobs

  http://svdc-txxx-bbnn:8088/cluster/nodes - monitor BigBench data node status

To check the status of BigBench services::

 ssh svdc-txxx-bbnn "/opt/createApacheCluster/checkHadoopStatus.sh"
