LMS – System Error – 10.25.2022 – Detail

At 7:45 AM Eastern on 10/25/2022 the Learning Management System experienced issues causing users to sporadically see an error message. The development teams were able to find the cause of the issue and have it rectified at 8:24 AM.


So what happened?
The system has multiple components that help it run effectively.. well.. most of the time. One of those components is a dedicated system to handle cache. (You may be familiar with browser cache.. same type of thing.) Think of cache basically like our LMS short-term memory. Users, throughout the day, make very similar requests to the system. Instead of having to calculate those similar requests each time a user asks for them, we store them in our short-term memory, our cache.
 
Unfortunately, the LMS has been telling our short-term memory space in our LMS brain, ‘hold on to this one. Don’t get rid of it. And this one too, and this one..’ They started piling up. We started to get short of space in our short-term memory.
 
The issue was experienced sporadically in various areas of the LMS as a memory error that read “Exception – OOM command not allowed when used memory > ‘maxmemory’.”
 
What did we do?
The team was able to do two things straight away:
1. Make the space in our LMS brain for short-term memory larger
2. Go through and clear out requests no longer needed.
 
We have also added more intelligence in the systems conversation about what should be held onto in the cache and for how long as well as better alerts when our short-term memory space begins to look like it might be getting full.

We apologize for any interruptions you may have experienced during this incident. We strive to be sure the system is available and performant for you and the training you deliver, and we will learn from this incident to improve on that commitment.

Test Generator Exams – 2011 NEC and 2012 70E – related Courses

The Legacy Test Generator has been undergoing a phase-out over the last few years. The legacy system was built on Flash. Flash has had a long and prosperous life for use in delivering online resources; however, that will end on December 31, 2020. As a result, this system will no longer function beyond 2020, and access to exams for all courses will only be through the LMS Assessments tool.

We have completed migrating exams from the Legacy Test Generator to the new Online Assessments system; however, Legacy Test Generator exams for 2011 Code-related and 2012 Electrical Safety-Related Work Practices (ESRWP) courses will not be converted. To support those program still using some of those older courses, we have created multiple exam versions in PDF format that you can request. For each exam version, we have three variances with the same set of questions shuffled across the three.

The following is the list of courses for which we have PDF exams available. To request exams and answer keys for these courses, please reach out to Steve Strickland by phone at 888.652.4007 or by email at sstrickland@electricaltrainingalliance.org, and let him know if you want different exams (different questions on each) or variations of the same exam (same questions shuffled).

For more information on the decommissioning of the Legacy Test Generator, please see those posts.

Legacy Test Generator Conversions Are Complete!

The Legacy Test Generator Decommissioned as of 12/31/2020

 

 

PDFs not displaying all pages in Chrome browser

The Chrome browser has made a recent change affecting how PDFs are displayed.  This is true when accessing some of our linked PDFs from our site just like it is from other internet sites.


The issue is that users are unable to view the entire document when opening that document in a Chrome browser.  The user may be limited to seeing the first page of the PDF and not being able to scroll to other pages.  The entire PDF may be viewed by downloading it to the user’s local device and opening from there.  Currently, this issue is specific to Chrome browsers.  We have found a solution to the problem and are addressing the issue as we find PDF documents showing the described symptoms.  If you or your students encounter this issue of not being able to view all pages of a PDF, please submit an errata ticket from within that particular lesson and then download the PDF for viewing or view it from within a different browser.


Thanks For Reading!

Review Mode Access Implemented

The following message was shared by Executive Director Todd Stafford to all programs on September 17, 2020, via Broadcast Memo.

As a reminder of this change happening, here is that message again, coming to you via the Blended Learning Blog. – Please have a wonderful weekend.


The electrical training ALLIANCE strives to meet the daily needs of our JATCs by continually improving curriculum content and delivering tools for the benefit of the apprentice. Following vNTI, we were asked by Training Directors about modifying some of the available settings in the Learning Management System (LMS). Our goal, just like yours, is and always has been to help the apprentice engage in quality learning during their apprenticeship and throughout their careers. With that in mind, last month, we sent out a survey to get feedback from you regarding two LMS settings: Activity Access Locking and Review Mode Access Locking.

  • Setting 1: Activity Access locking is the minimum proficiency level a student must achieve to complete the lesson practice or items to advance to the next lessons or items.
  • Setting 2: Review Mode Access locking is the minimum effort level required for the student to access and review lesson practice performance.
    • In Review Mode, the student can review their answers to questions, how it is scored (correct, incorrect, partially correct), and reveals what the correct answer is to each question and any provided solution notes or descriptions.

For a review of the full descriptions of these settings, please access this link. (Be sure to click on the image to view the full 2-page PDF)


The results are in. Thank you to all those who participated in the survey. We heard you, and we are taking action. The positive responses and thoughtful comments that we received regarding both features were outstanding and appreciated. It is together that we will best provide solutions to help in training within this industry.

The two settings that we were asked to survey you about require different levels of effort to enact and maintain.

  • Setting 1: Activity Access Locking will NOT be administered at this time, but at a later date following SME input per topic, Training Director input, and follow-up communications. Please note, no setting will be administered without clear communications about the timeline and any program or user impact.
  • Setting 2: Review Mode Access Locking will be available for all courses that do not currently have this setting starting on September 26th. There are a few details to share regarding how this setting will be applied.

Based on your feedback to the survey, we have determined to begin using this setting at a 60% level. This setting is not at all to state that anyone believes 60% is an acceptable value of proficiency on coursework; however, we are merely modifying what is currently set at
0% and raising the minimum level of effort on quizzes to access a quiz review to 60%. This, in turn, continues to allow you and your programs to administer local policies on performance requirements. The use of the report data continues to enable you to administer your own local response to performance requirements.

To say it another way, your JATC’s local policies and procedures should still dictate the successful coursework completion requirements as this setting does not make any changes to the construct of what you have made for your apprentice requirements.

Widespread Internet Outage – 08/30/2020

An internet outage affected the electrical training ALLIANCE systems today, (8/30/20) as it did many other providers.  The issue was found to be with a third-party internet transit provider incident with Century Link that then cascaded to affect many other services.  This meant services like Cloudflare, Hulu, the PlayStation Network, Xbox Live, Feedly, Discord, and dozens of other services, like ours, reported connectivity problems Sunday morning.  Please see this post for more details.

We saw issues appear on our monitors with the LMS, TMS and the IC systems just after 6:30am EDT Sunday.  These issues were intermittent but began to stabilize fully just after 11am EDT.  A notice was posted to the login pages of all systems, as well as status on onlinesystemstatus.org.  These notices were pulled down following recovery of the programs.

We have a team continuing to monitor the situation and will post updates as needed. We know how important these services are and will continue as always to monitor and communicate regarding site access.
