Description of Virtual Testing Environment

Please view this document in entirety in PDF format at http://www.ehealth.va.gov/docs/mass/TCMS-Description_Virtual_Testing_Environment.pdf

A virtual testing environment has been configured to provide an on-line environment in which submissions to the scheduling contests can be evaluated in a fair and objective manner.

Background

This virtual testing environment satisfies the following requirements:

  • Provides a representative multi-site VistA configuration.
  • Provides a largely identical environment for evaluating all contestant submissions.
  • Contestants will have sufficient control of the virtual machines (VMs) in which they will prepare their submissions.
  • Upon submission, evaluators will have a standardized environment in which they will be able to review each submission.
Specification

The virtual environment is composed of a collection of VMs that will be made available to contestants through remote connections via username/password secure logins.

Each contestant will receive access to three VMs, and will have control over them for the allotted time of submission preparation. At the submission deadline, Veterans Affairs (VA) evaluators will take control of the VMs and will initiate the submission reviews.

The machine’s clocks have been set to different time zones in order to exercise some specific scheduling scenarios. During the testing process, contestants may have to change the date and time in the clock, but must not change the time zone.

VM-1 Description

This VM is built on a Windows Server 2008 - 64 bits operating system. It has Intersystems Cache installed, and the VistA VISN0 version used by the VA Innovation Sandbox. Its time zone is set to California, Pacific Daylight Time (PDT).

Contestants can login to this VM using “remote desktop” clients and the username and password provided in their registration package.

This VM will also have an installation of CPRS (Computerized Patient Record System) that is compatible with the VistA installations.

VM-2 Description

This VM is built on either a RedHat Enterprise Linux 6.1 or a Windows Server 2008 operating system, depending on contestant preference (see Table 2). It has Intersystems Cache installed, and the version of VistA-FOIA dated August 24, 2012.  Its time zone is set to Alabama, Central Daylight Time (CDT).

If using Linux, contestants can login to this VM using “ssh” clients and the username and password provided in their registration package. If using Windows, contestants can login to this VM using “remote desktop” clients and the username and password provided in their registration package.

 VM-3 Description

This VM is built on a RedHat Enterprise Linux 6.1 or a Windows Server 2008 operating system, depending on contestant preference (see Table 2). It has Intersystems Cache installed, and the version of VistA-FOIA dated December 6, 2011.  Its time zone is set to Georgia, Eastern Daylight Time (EDT).

If using Linux, contestants can login to this VM using “ssh” clients and the username and password provided in their registration package. If using Windows, contestants can login to this VM using “remote desktop” clients and the username and password provided in their registration package.
