• Proctor caching computers must run on the same network as the students’ testing computers. 
• If you need to update ProctorCache to a more recent version, uninstall the previous version. Then, reboot the computer and install the more recent version. You can uninstall ProctorCache using the software removal process for your operating system.

Additional Information

• ProctorCache does not require special hardware or server equipment.
• You should not install ProctorCache on a computer you intend to use for student testing.
• A typical installation takes approximately 10 minutes per proctor caching computer.

If you are not a network administrator, proctor caching requires:

• Full local administrator permissions
• Working knowledge of your network

• If possible, proctor caching computers should have a network connection of 100 mbps full-duplex or higher. The minimum network connection is 10/100.

• You should verify that your network is set to use IPv4 DNS (Domain Name System) servers. 

  Currently, IPv4 is the standard method for how computers communicate with each other. Because there are a finite number of IP addresses that can be used with IPv4, a newer version, called IPv6, was developed. An example of an IPv4 address is 192.168.1.1, and an example of an IPv6 address is 2012:0db8:85a3:0000:0000:8a2e:0370:7334.
  If you have not made any explicit changes to use only IPv6 for DNS, you should not have any issues.

• The proper configuration results in TestNav and your proctor caching computers communicating with one another. If you do not have any network issues between these computers, no action is required. If there are problems, contact your network administrator.

Multimedia files are very large content elements, and you must cache these prior to starting the test session. Pearson recommends that you dedicate a separate computer as the proctor caching computer for media test content.

The variables that impact the number of media tests that TestNav can deliver from a single caching computer include the test size itself. It is expected that for traditional audio tests with relatively small audio clips or for video tests that have a limited number of clips, the ratio of students to proctor caching computers can be increased.

Pearson occasionally fields requests for assistance with silent installations (Windows only) or with installing on multiple machines at the same time.

If you are certain the default Windows options work for your organization, you can perform a silent install.

Pearson does not support any device or method for simultaneously installing ProctorCache onto multiple machines. Pearson does not supply any information or an MSI file for this method; however, users have reported creating their own MSI file and using them with great success.

1. Double-click the shortcut to ProctorCache to open it.
2. Click the Tests tab, and click the test or form name.
3. Review the caching status of all items in the test form. Each URL represents item content, along with the number of hits, which can provide some indication of the number of students who have accessed the item.
   1. Test Status are as follows:
      • Green OK – content is successfully cached.
      • Yellow Not Loaded – content is not cached.
      • Yellow Waiting... – content is waiting to be loaded.
      • Yellow Loading... – content is currently loading.
      • Red Failed to load content – caching content failed. 
      • Red MD5 Check Invalid – MD5 comparison failed.
      • Red MD5 Mismatch – MD5 comparison succeeded, but files did not match.

1. Double-click the shortcut to ProctorCache to open it.
2. Click the Tests tab, and click the computer name.
3. Review information about an individual client that has recently requested test content. The Status field indicates client activity.
4. Client Status are as follows:
   • Green OK – client is active.
   • Yellow Idle – 5 to 30 minutes since client was active.
   • Yellow Long Idle – 30 minutes to 12 hours since last activity.

Clients are removed after 12 hours of inactivity.

1. Connect to ProctorCache on your local host - http://localhost:4480/settings.jsp.

   If you access ProctorCache from a remote computer using an IP address (for example, http://10.25.99.142:4480/contents.jsp), you cannot view the Settings tab, which contains the option to change the default password.

2. Click the Settings tab, and you will see the following:

   Click to enlarge.

   
3. Enter the old password, and then enter the new password twice in the required fields.

4. Click Submit.

If you forget your password, the administrator can reset it to the default password:

1. Open the properties file, located in ProctorCache > jetty > etc > proctorcache.properties. 
2. Within proctorcache.properties, find proctorPwd= and delete the current password.
   • The password in the proctorcache.properties file is the encrypted version of the password.
   • Deleting the password in this file causes the system to use the default password. 
3. Restart ProctorCache.

After restarting ProctorCache, you can click the Settings tab to reset the password again.
