Beta Browsers

Internet Explorer - Use IE6 or IE7
At this time Internet Explorer 8 is in Beta and will not work with Tegrity consitently. Tegrity will update their software only once this version is in Release.

Google Chrome - Don't Use
Google Chrome, also in Beta, will not work with Tegrity. Once again Tegrity will update their software once it is in Release.

Firefox - Use older Only
Tegrity Works inconsistently with V2 and not with V3

Bottom line is use IE7 until browser versions settle to release.

No More Skipping!

The PowerPoint Skipping problem has been resolved.

If you are still having difficulties with Tegrity playback please call us at 407-459-4572

Tegrity Podcast

The Tegrity Podcast feature will not be available for the next few days. The M4v files are currently making the size of the lecture downloads rather large. Tegrity is aware of the problem and is working on the issue. As soon as the issue is corrected, we will post on the blog to let you know the Podcast feature is available again.

Skipping Lectures

We are now fixing all lectures from the first week of classes that had skipping problems. These should be completed by Friday.

Tegrity Server UP

Everything is running normally now.

"Why don't I see my lectures then?"

Because we are uploading them continually. Please be patient while they upload and process so that you can view.

Tegrity Server Down -> Status Update #2

We are still in the process of uploading lectures.

Tegrity Server Down ->Status Update #1

We have replaced the failed drive and completed the re-install of the Tegrity server. We are in the process of uploading lectures.

Tegrity Server Down

We had a major hardware failure Saturday night. We are working to restore the server. You will unfortunately not be able to view lectures until we fix the server and re-upload the lectures.

Tegrity Server Update

The Tegrity Server will be down for the next few hours due to a Tegrity Update. The Server will be up by 6pm.

New Tegrity Player

Starting in June we are introducing a new Tegrity Player. The new player will have a new look with some additional features. For the most part it will be the same player you are familiar with using.


For more information on the new player:

Power Outage

There is currently a power outage in Engineering III (Harris) where the Tegrity server resides.

Electricians are working on the problem.

Network Problems

If you are having trouble viewing lectures it may be due to campus network problems. This was sent out today:


"We are seeing intermittent network outages affecting part of the campus
network at this time. Our NOC staff are working on the issue and we are
working with CISCO support to diagnose the source of the problem. We
don't have an estimate for when the problem will be resolved, which
began earlier this morning."

Macintosh Compatibility

Some students with older Macintosh's have been experiencing issues with streaming. I will post the solution and an explanation below.

The problem lies in the differences in hardware architecture between older Macs (Power PC based) and newer Macs (x86-Intel based). Currently a if a Mac user new to Tegrity attempts to stream a lecture, they will get a prompt to install a plug-in. The plug-in is designed to run on x86-Intel based macs only. If the user has a Power PC based Mac, the plug-in installation will run but streaming from Tegrity will still fail. Users with x86-Intel Macs will not experience problems. The solution for Power PC users is to download the correct plug-in. I have provided a link below.


http://mirror.facebook.com/videolan/vlc/last/macosx/vlc-plugin-0.8.6b-powerpc.dmg

Download this plug-in and run the installation. Restart Safari when the installation has completed. Power PC Mac users will then be able to stream using Tegrity.

We are working on integrating the Power PC plug-in into the plug-in download screen on Tegrity. Thank you for your patience.

Problems viewing from home.

Please keep in mind that these problems are only happening with some routers and some ISP's. COVE recommends LinkSys WRT54G or better router.

Problems viewing from home...

We have analyzed this and this is what we found.
Direct connection of the computer to the ISP providers modem solves the problem. When using a router the system never starts playing. The hang observed is seen as a continuous flashing of Buffering/Playing but the video never starts. This is caused by your ISP. Some ISP providers intentionally limit connections when you are using a router. This is because they typically like to charge your per connection. There is a workaround...if you connect to UCF utilizing the Virtual Private Network (VPN) connection you form a logical connection to UCF that the ISP is less likely to be able to limit. You can find information about creating this connection at: UCF VPN Help. This is easy to set up and should solve the problem.

Server Maintence

In order to perform server maintenance, the server will be down for approximately 5 minutes every day at 12:00am and 12:00pm. Please plan your viewing accordingly

Server Status

Many changes have been made to the Tegrity server. The first change is more efficient downloads. On average there is only a 5 second delay for classes to begin downloading. The second change is disabling of DRM activex controls. This allows for more reliable viewing of downloaded files. The 3rd change relates to load time of webpages on the server. It should be noted that in order to insure Macintosh compatability, we had to reprocess every class currently on the server. This was started at 6:00am. We expect this to be completed by 10:00am. This means that some lectures may not be available until later in the morning or early afternoon. I would like to thank everyone for their continued patience. I would like to note that these problems were not a result of the Tegrity system by itself. There were many contributing factors relating to our implementation specifically. Tegrity has been generous in their offering of support for UCF and have even gone as far to rewrite server code specifically for our school.

Classes

I just finished reviewing all classes. To my knowledge all are present. Please report any problems using the Tegrity Support ticket system. This can be found at http://tegrity.ucf.edu/support

Classes

All classes will be unavailable from 1:30am August 26th until 8am August 27th

Classes

The Tegrity server is working well. There is however one concern. During the rebuild of the Tegrity server we noticed that some classes were missing. We went through all the classes and fixed the missing classes. Even though all classes are present to the best of our knowledge we would appreciate it if you could report any missing classes to us.
Email: gsapp@mail.ucf.edu

Support Ticket System

The support ticket system has been fixed and updated. You may use it to report any problems you have.

Tegrity Server

As of 5:00am August 25th the server has been up. Many issues were addressed including server stability problems and performance enhancements. We updated the Tegrity server player. This enabled Macintosh streaming as well as fixing that double audio problem some users were experiencing. We are still working on improving download performance. Many students have complained that it takes a long time for the server to offer them a file to download. We have identified the issue with this and plan to finish fixing it some time this weekend.

Thanks,
George Sapp

Server Status

We have identified the problem specifically and are currently working with developers to resolve it. In the meantime, I have enabled the old feeds system so you may stream and download your classes.

Double Audio

The double audio or echo seen this afternoon is being fixed. We must restart the server but it will be back up shortly

Server Status

As of 12:00pm today service was restored. We expect any further issues will be minor in nature. Limited Macintosh streaming capabilities have been enabled. Users with intel macs will be able to stream immediately. Users with Power PC macs will have to wait a bit longer for streaming. We are currently making the modifications necessary to enable streaming for Power PC Macs. Although MAC streaming is available we still recommend that mac users download lectures. Please be patient while downloading. In some cases it can take several minutes for downloads to begin. We are also working on a fix for this. Thank your all for your patience and cooperation.

We have been working on the server all night and are almost completed. At the moment we are loading class content so you may not see any lectures in your course. Please check back at 10AM.

Tegrity Server

The Tegrity server has been experiencing intermittent outages over the last couple days. We are aware of this problem and are working at full capacity to correct it. The issue is expected to be resolved before 8am August 24th. Despite it's appearance the system is very new in may ways. May adjustments are being made to ensure reliable streaming and maximum availability. We appreciate you patience and apologize for any inconvenience this may cause.

Thursday DRM Issues

A patch reset the DRM option on the server. This may give you a "DRM error"

This is being changed right now....please try again in about 1 hour

Server Status

We discovered an error on the server that was corrected last night. You may have noticed an interruption in service from 2am to 5am. The server should offer better streaming performance now.
