Network Requirements6Network ConnectivityAll workstations used for student testing should have access to the Internet and should be able to access the servers using HTTP/HTTPS protocols on ports 80 and 443

Firewalls at the local workstation and the network level should allow Java connectivity on ports 80 and 443All the URL’s corresponding to the testing servers should be whitelisted on content filtering or other proxy software used locally




Monitoring Software - Prohibited7If your testing location uses remote desktop monitoring software to monitor the computers that will be used for testing, you should disable the monitoring software on these computers during test times to guarantee adequate security.

The particular steps you need to take vary, depending on the monitoring software you are using and the operating system of the testing computer (for related information, see “Operating Systems, Hardware Devices, and Virtual Desktops”)Note: If it is not feasible to disable your monitoring software, you must ensure that any staff members that can use the monitoring software refrain from using it during testing periods

LCS Overview9

Local Caching Service (LCS) – The LCS has three roles:

Reduces bandwidth by caching the test content

Provides the ability to save responses if the internet connection between the testing site and DRC is temporarily lost


the Load

Simulation Tool for required System Readiness testing (new in 2013)


LCS Installation – General10Same system requirements as the test engine with two exceptions: requires 1 GB of available hard disk space or greater needed to cache the test content, and 1 GB of RAM or greater to run the Load

Simulation ToolRuns on a computer within the local networkInstalled using an installation wizard; requires administrative rights Populated with test content using the LCS Manager; test content updates are automatically downloaded

Student workstations must be connected to LCS or Internet; otherwise test will terminateLCS highly recommended

for caching whenever possible



for the Load Simulation Tool

Reference the Technology User Guide for further installation details


LCS – Changing the Port Number11Windows, Mac and LinuxAfter the LCS is installed, if this port is already being used or conflicts with firewall settings, you can change the value by reinstalling the LCS or by updating the following file: <installation dir>/apache-tomcat-5.5.29/conf/server.xml

Before you change the port number you must stop the LCS. After you have changed the number, you must restart the LCS


LCS Manager – General12Use the LCS Manager software to manage your LCS. The LCS Manager software helps you keep your test forms current and transmit responses for scoringTo start the LCS manager, select Start–All Programs–WA Online Assessments LCS–WA Online Assessments LCS Manager


Bandwidth Calculator13Estimates the time it will take students to download tests and upload test results to help sites plan their testing based on a number of factors, including the time of day, the current network traffic, and the number of students testingUses sample data transferred from the LCS in its calculation of the time it takes for data to go to DRC (#1 in the figure) to estimate the upload speed of a testing computer to DRC (#2 in the figure)


Bandwidth Calculator14The site can enter a different value if they have a more realistic number based on knowledge of their environmentThe site enters the number of students who will download or upload tests on the school or district network at roughly the same time (concurrently). All students do not start and finish a test at the same time, so this number indicates a worst-case scenario


Background on the Load Simulation Tool15The purpose of the rest of this presentation is to outline the steps necessary to run the Load Simulation Tool

This new tool will trace the entire route of the student data from the student workstation to the DRC servers

This simulation is required as part of the System Readiness Checklist

The simulation does require the new version of the Local Caching Service (LCS)

(the client



on March 6,


The simulation is activated via the LCS


Setting Up the Load Simulation ProcessThe Load Simulation Process requires an updated version of the LCS and the student workstation software have been installedFirst, you select the Enable Load Simulation

option of the System Readiness Check to put each workstation in simulation mode. Then, you use the LCS Manager to run the simulationThe Load Simulation Process will use 1 GB of memory on the machine running the LCS



Setting Up the Load Simulation ProcessTo confirm that the LCS is running, pull up the LCS Manager page. If it comes up, the LCS Tomcat service is runningNote the LCS and Simulation Server Name and the

LCS and Simulation Port Number. That information will be needed to set up the simulation settings on the student workstationsWhen the LCS Manager is launched

the first time with the updated release, a window will pop up and

prompt you

to select


district from a

list. Select your district and ensure it is correct before you click


. The simulation results are tied to the district name that is selected in this step



Setting Up the Load Simulation Process 18At each workstation to be included in the load simulation process, launch the System Readiness Check

Within the System Readiness Check, select Settings–DRC INSIGHT Properties


Setting Up the Load Simulation Process19If the workstation is configured to the LCS the LCS and Simulation Server Name and the LCS and Simulation Port Number

fields will be populated. If not, you will need to manually populateThe Enable Local Caching Service checkbox indicates whether the simulation downloads the test content from the LCS or DRC


Setting Up the Load Simulation Process 20The Unique Machine Name will be automatically populated; however you can update it to any value you choose to make the workstation more identifiable in the simulation. This name is what will appear with the results

Checking the Enable Load Simulation box will put the workstation in simulation mode

Complete these steps for each of the student workstations to be included in the simulation

These steps will need to be completed for each simulation


Running the Load Simulation Process21Launch the LCS Manager and select the

Simulation tab and then the Simulate Tests tab. This tab displays the number and name of each workstation included in the simulation and the Status displays as

ReadyReview this list to ensure that all workstations intended to be included in the simulation are listed under Details


Running the Load Simulation Process22Select the Run Simulation button to start the simulationThe status will change to

In Progress and the Run Simulation button changes to Stop Simulation

If the simulation is stopped prematurely, no results will be presented and each workstation will need to be set up again


Running the Load Simulation Process23Each of the student workstations will display a simulation completion message

Select OK Now you have the ability to close

the System Readiness Check application as the simulation is


If you want to

run another simulation, repeat

the process


Load Simulation Results24Once the simulation is complete, the results will be displayed in the Simulate Tests

tab and the status changes to CompleteThe simulation will time-out after 10 minutesNote that these results will vary based on the number of student workstations included in the simulation and network configuration in your district


Load Simulation Results25Evaluate resultsLook at the average load and submit times

Look at the load and submit times for each computer to identify any outliersTroubleshooting results

Does the computer have enough memory?

Is the network connection

working as expected?

How is the computer set up

the same or different than

successful computers?


Load Simulation Results26In the Historical Data tab, you can view the results of one or more simulations that you selectThe results are sorted by Maximum Duration and Simulation ID. You can click on the column heading to re-sort the data


MSP Technology Readiness Checklist27Action Required by Friday, April 12Helps prepare for a successful online testing experience
