Adobe Connect Meeting becomes Unresponsive with Clients Running Mac OS X 10.9 Mavericks

Adobe Connect supports Mac OS X 10.9 (also known as Mavericks). In some rare instances clients running Mavericks consistently experience freezing and disconnection issues. The root cause has not yet been identified; here are recommendations that have addressed the issue for some users:

-        Ensure latest Adobe Connect add-in and Flash Player are installed:  https://www.adobe.com/support/connect/downloads-updates.html

-        Set the correct sand-box settings in Safari as documented in these tech-notes:

Apple support also provided these recommendations:

-        Enable Sandbox mode in Safari. Make sure you have the Adobe Connect room open when you try and add the webpage.

-        Change the DNS settings to Google’s server, and disable prefetching. Make sure that you reset the computer after changing the DNS: http://support.apple.com/kb/ts3408

We have not reproduced this issue with either OS X 10.9.5 or Mac OS X 10.10 (also known as Yosemite).

The issue is still under investigation with Adobe and Apple.

Web Services API call: sco-session-seminar-list

We have opened a bug around a recent undocumented change in the Web Services API actions.

The action, sco-session-seminar-list, which prior to 9.2.2 returned all seminar sessions for which the authenticated user had Host permissions, now requires the alternative action: sco-seminar-sessions-list. Use sco-seminar-sessions-list instead of sco-session-seminar-list until we resolve the open issue around this change; we have logged bug number: Watson: 3772441.

Consider this sample action (wherein FQDN designates your fully qualified domain name) as an example: Instead of running the action:  https://FQDN/api/xml?action=sco-session-seminar-list&sco-id=1369951914 to get all the seminar sessions under the seminar license with the sco-id of 1369951914 you ought to run this API instead: https://FQDN/api/xml?action=sco-seminar-sessions-list&sco-id=1369951914

To list all the sessions that are linked to a meeting room under one license, put a filter on the source-sco-id as in this example action: http://FQDN/api/xml?action=sco-seminar-sessions-list&sco-id=sco-id-of-the-seminar-license&filter-source-sco-id=sco-id-of-the-meeting-room

Ensuring that Email Generated by Adobe Connect Servers is Received

There have been more than a few incidents reported on the topic of email messages from Adobe Connect servers not getting delivered. These include messages generated by the Adobe Connect Events module as well as system email messages such as that generated by changing a password.

The first thing to avoid to prevent this problem is that of using special characters in the host’s name. This is scheduled to be fixed in Connect 9.3, but currently, in 9.2, if you place a comma in the Event host’s name such as Frank D., El Presidente’  it will cause an error identified in our server logs by a messaging exception.

The second thing to avoid is inviting over 20,000 participants to an Event. This generates an operation size error and causes problems with email messages being sent out. We also plan to address this ceiling tentatively in Connect 9.3.

With specific reference to Adobe Connect Hosted accounts, we just made the following change to ameliorate email problems: As of April 28th, 2014, administrative email notifications sent from Adobe Connect servers will now be coming from admin@adobeconnect.com instead of admin@acrobat.com This will help by disassociating Connect-generated email from that of the Acrobat domain which could be potentially blocked by virtue of its identification with document storage. We also made some internal changes to the way the Connect servers handle email and we worked with our Web infrastructure partners to insure that Connect generated email was not being treated as SPAM on the Web.

There is a bit of a conundrum here. If Adobe Connect Events email invitations are sent out in massive mailings to those who perceive the email as SPAM, then the Adobe Connect servers could be tagged as producing SPAM by those end-user recipients. An overzealous Events manager may cause Gmail and other providers to treat Adobe Connect email as SPAM. When an Event that is capped at 500 participants sends out 5000 email invitations, it is expected that many recipients will at best ignore the inbound email traffic and many more may consider the traffic to be a nuisance. We are investigating possible approaches to ameliorate this problem and plan in 9.3  to add an opt-out option for Events invitations that will offer a convenient alternative to any SPAM reply option for recipients to invoke.

We love large Events and Adobe Connect handles them very well; this is a case when our success can potentially lead to some problems. Currently the Adobe Hosted Service is green for SPF record checks.  We pass all major email providers and are not blacklisted according to common checker tools on the internet.  This should resolve the lion’s share of current email issues and the upcoming changes in 9.3 will serve to harden this capability for future Events.

How to make Connect use a browser-based email client to send Meeting invitations

When invoking a browser-based email client to invite participants to a Connect Meeting from within a Connect Meeting you will see this error message unless you first make the browser-based email your default email service:

 

bb-email.fw

 

Sending a browser-based email invitation from within a Connect Meeting is possible if you first make the browser-based email option your default email program. As an example, you can use the instructions at the following links to make Gmail your default email program :

http://email.about.com/od/gmailtips/qt/et_default_prog.htm

http://www.pcdailytips.com/set-gmail-as-default-email-using-chrome-or-firefox/

Note that once you enable a browser-based email client and invoke it from within a Connect Meeting, the behavior will be different based on whether the host issuing the invitation is using the Connect Meeting addin or the Flash Player. In the addin it will look like this:

Using the Connect Meeting addin, invoke the invitation: Meeting> Manage Access & Entry > Invite Participants

bb-email-1.fw

bb-email-2.fw

See how the invitation is fully populated with important details:

bb-email-3.fw

Following the same procedure using the Flash Player instead of the addin (?launcher=false) also works, but with an abbreviated invitation message:

bb-email-4.fw

Be Aware of the Closed Captioning Pod Defaults

Last week we found out that Caption Colorado changed their IP address and port number for the Closed Captioning pod downloadable from the Connect Exchange Website. Here is the direct link to the Connect version 9 Closed Captioning Pod

The new Caption Colorado information includes:

If you are experiencing any trouble with the Closed Captioning pod while using it in a Connect Meeting with Caption Colorado, please set your host to “captionedtext.com” and to port 11100 in the adobe pod. Note that the new IP, 54.193.31.11, depending on your infrastructure’s network security settings, may need to be white-listed.

Estimating the Size of Archive Meeting Recordings

I was recently asked if I had any test data showing how big a recording becomes based on the use case during the Connect Meeting being recorded. While plenty of anecdotal information exists,  I thought it prudent to begin a list of use cases and show what the size was after five minutes of each use case. This article will be a work in progress as I add different use cases in order to offer various concrete examples to use as a basis to estimate recording size based on what is being recorded, whether multiple Video pod camera feeds or screen-sharing or VoIP, etc. Among its purposes, this exercise will help meeting hosts to avoid exceeding the 2GB limit on Adobe hosted clusters for recording size.

Most relevant among the variables considered is the notion that recording size is affected by the streams present in the meeting being recorded. Typically a Video pod with VoIP (640X480) shared per hour will result in an FLV of around 200MB. Sharing a screen in a meeting (1680X1050) will result in an FLV size of around 150 MB. PPT/PPTX files uploaded to a meeting room and displayed while recording will not play a significant part in recording size because the recordings link to external content rather than contain that content intrinsically. For example,  a meeting with two Video pod streams could have recording size of around 400MB and a meeting having a single Video pod stream with VoIP and screen-sharing could end up around 350MB. The actual results may differ as the screen resolution of the publisher, the type of sharing and the amount of movement are all variables that can affect recording size: If there is little movement on screen or in the Video pod stream, the recording size will be less than it would be with a lot of movement.

Here are some concrete examples to use for planning; each recording is approximately five minutes in length:

How Meeting Folder Permissions Affect Access to a Meeting Room

The question keeps coming up, what happens to Meeting accessibility and permissions if I move a Meeting room from the a User Meeting folder to the Shared Meetings folder?

Let’s look at it from multiple angles beginning with the permissions on Shared Meeting folder itself and then moving to the Meeting room access options and then to the Meeting roles.

1. The Shared Meeting folder itself has two permissions options: Manage and Denied:

sharedfolderperm.fw

If a registered user is granted Manage permission over the Shared Meeting folder by an Administrator, then that registered user can gain (at a minimum), participant access to every meeting in the Shared Meetings folder. Of course, a participant can do very little within a room:

sharedfoldermeeting.fw

Manage permissions on the Shared Meetings folder does not, by itself, allow the power to change room settings. The settings will be viewable but cannot be changed:

editinfo.fw

Clicking save will quickly manifest insufficient permissions:

notauth.fw

Manage permissions on the Shared Meeting folder allows for deletion of  a meeting in the Shared Meetings folder:

delemeet.fw

delemeet1.fw

2. Separate from the Shared Folder permissions, are the room access options under Connect Central for any Meeting Room:

editinfoopt.fw

These Meeting access options do not override the folder options. While a user with Manage permissions over the Shared Meetings folder will still need to enter a passcode if one is set, the manage permissions allow the passcode to be viewed in Connect Central :

passcd.fw

 

passcdview.fw

3, Meeting roles set will not be affected by folder permissions even if the Denied Access is chosen at the Shared Meeting folder level:

denied.fw

A user who has Denied access to the Shared Meetings folder cannot view the the folder Connect Central:

notauth.fw

Meeting access permissions and roles apply however when directly hitting the Meeting URL even if the user is denied access to the Shared Meetings folder:

notstart.fw

in.fw

 

How to Find and Administer a Meeting by Searching on its URL

Problem: Sometimes the meeting library in Connect become quite large and it may be difficult for an administrator to find a Meeting room that has been created by a host.

Solution: Generally a meeting created by a host will be under the user directory of that host (My Meetings for that particular Host), but not always. The User Meeting folder can contain hundreds of different meeting folders and scrolling through them page by page by page in the Connect Central GUI can be laborious.

usermeetings.fw

Next Page…. Next Page…. Next Page…..

nextpage.fw

One simple search trick is to place a number directly in the start parameter of the URL to skip to subsequent pages and user meeting folders. Here I have replaced the starting number of “0″ with the number “500″ and when I refresh the screen it will skip folders and accelerate my search:

start.fw

start500.fw

Note: You may also adjust the rows URL parameter as well: rows=1000

When you want to find a specific meeting to administer and you know the URL, a quick way to find the meeting folder in Connect Central is to use the Custom URL Report under the Administration Tab>Reports>View Custom URL:

customurl.fw

Our labeling of  this search option, “View Custom URL” is really is a bit of a misnomer because you can search for any meeting by its URL whether the URL is custom or automatically generated by Connect in Connect Central; all URLs are obviously unique. Here I search for a meeting URL with the suffix “es” on the platinum domain and it shows me the meeting information which gives me a hook that makes it very easy to find that meeting folder to administer:

searchedge.fw

Now simply take the title of the meeting and place it into the Connect Central search parameter to find the meeting folder:

searchtitle.fw

Connect Central has some great tools even if the possibilities they offer are not always intuitive.

How to completely delete content from a Meeting room

To completely delete content from any meeting room there are at least two places and possibly a third place in Connect from which you must delete it.

The first place is the most obvious and it is in the Meeting room itself under the Pods menu and Manage Pods option:

del-con.fw

del-con1.fw

The second place is in the Uploaded Content directory under the Meeting Information. To get there from a Meeting room, a host and owner can click Manage Meeting Information under the Meeting tab:

del-con2.fw

Then go to the Uploaded Content tab:

del-con3.fw

The third possible place is the Content Library. If you uploaded or published to the Content Library and pointed the share pod to it, you will need to go to the Content Library to delete it. If you uploaded directly to the Meeting room then you may skip this step:

del-con4.fw
