Preparing for and delivering a training class

This document provides information for instructors delivering classes with Skytap lab environments.


For best practices on building a virtual classroom in Skytap, see Using Skytap Cloud for training classes.

Before the class

  • Determine your Skytap administrator or point of contact. If you do not have a Skytap user account, determine the person within your organization (or your partner organization) who can access and edit the student lab environments on your behalf. You may need to contact this person to resolve access or configuration problems on the VMs.
  • At least one week prior to the scheduled class, test that each computer used for the training meets the minimum access requirements.
    Complete these tests early to allow sufficient time to troubleshoot and/or resolve any potential issues.
    1. Use one of the student computers to perform the following tests:
      • Connectivity Checker – This test confirms that the computer meets the minimum requirements for accessing Skytap VMs.
      • Speedtest – This test confirms that the site meets the minimum bandwidth requirements for hosting a class (1.2 Mbps for each concurrent browser session with a VM). For example, if you have 15 students accessing Skytap VMs from the same physical location at the same time, the minimum recommended amount of bandwidth is 18 Mbps.


      • Run the Speedtest from the same physical location and on the same internet connection the students will be using.
      • Run the Speedtest several times—during off hours and during a period of high network usage. This establishes a baseline for the network capacity and expected performance.
    2. (Recommended) Install the latest version of Google Chrome (download) on the student computers. Chrome provides the best performance for accessing VMs through the Secure Remote Access (SRA) browser client.

    Send each student the following email at least a week ahead of the class. The email instructs students to use the Connectivity Checker to test their computer against the Skytap access requirements.

    Replace US-West with the correct region for students to test their network performance against.

    To prepare for your upcoming training session, please take a few minutes today to:

    • (Required) Run the Connectivity Checker test from the same computer and network that you plan to use during the training session. This test confirms that your computer and network meet the minimum requirements for accessing your virtual lab environment.

    • (Recommended) Install the latest version of Google Chrome (download). Chrome provides the best performance for accessing your virtual lab environment.

    If you have any problems or questions related to the requirements, contact Skytap Support ( as early as possible.


    • If the connectivity test fails due to a security restriction on the network (for example, a corporate firewall or proxy server) and if the student cannot get the Skytap IP addresses and ports whitelisted prior to the class, ask the student to attempt access from a different network (for example, from a home network instead of from a corporate network).
    • If the latency is higher than 150 m/s, ask the student to test against another Skytap region. If the student experiences better performance with another region (and if your company’s Skytap account is configured to allow access to that region), work with your Skytap point of contact to move the student environment to that region.
  • At least one day before the class:

    • Verify that the student sharing portals are properly configured (for example, confirm that the student has the right level of access to the VMs). Work with the Skytap point of contact to make any necessary changes to the access levels in the sharing portals.
    • Confirm that any VM credentials saved with the VMs are correct.
    • Send each student the sharing portal URL link for his or her lab.

During the class

During the class, you may need to help students resolve issues with their lab environments. The sections below provide helpful information for troubleshooting issues.

Issues with connecting to a VM or with slow VM performance

Students can solve most connectivity and performance issues with our self-guided troubleshooting assistant (TM_Home.html). To preview this troubleshooting assistant, click below.

Start troubleshooting

If the student cannot resolve the issue with the troubleshooting assistant, contact Skytap Support via the support page or via email at Include:

  • The name of the company you’re working with.
  • A detailed description of the issue.
  • The troubleshooting steps taken to date.
  • The URL of the environment or sharing portal page. The URL is listed in the address bar of the browser.

    (For example:…)

Issues with the VM operating system or applications installed on the VM

Work with your Skytap administrator to resolve issues with:

  • Missing or incorrect usernames and passwords for the VM operating system or applications on the VM.
  • Applications or databases on the VM that won’t load or that don’t work properly.

Skytap Support does not manage data, accounts, or applications within the VMs.

Other issues

You can use a student’s sharing portal link to access the environment at the same time as the student. This access can help with guided learning or troubleshooting.
