Web Conferencing question

I have a question about web conferencing. We are looking for a product that would allow us to do a desktop sharing for remote support purposes and web conferencing seems to have that capability.
I'd like to install a test instance of the collaboration suite + web conferencing and I have a few questions about it:
1. Does the web conferencing require release-2 of the Collaboration suite, or release-1 will be Ok as well?
2. The web conferencing download exists only for Windows, and downloadable only when I chose Solaris platform. Will it (this download) work with the rest of the software (Collaboration suite) installed on a different server (e.g. Linux or Windows)?
If we decide to buy it, do we need to install this on Windows, or the installation exists for another platform (e.g. Linux or HPUX)?
3. The download includes both Application Server and Web Conferencing as two separate options. do I need to have download server?
4. If I am looking ONLY for web conferencing capabilities, which pieces of software in Collaboration suite do I HAVE TO install?
Thanks.
Alex.

It is worth noting that the Windows download also includes the Voice Conversion server. This part of Web Conferencing runs only on Windows and provides support for streaming audio from a phone conference to attendees in a web conference as well as recording the voice data with the web conference data for later playback.
However, this functionality requires special Dialogic hardware and a dedicated T1 phone line so it is typically not deployed for pilot instances.
As far as the three required components (OCS infrastructure, OCS midtier, and OCS storage database), there is no requirement that they run on a single platform, although that is often most convenient. The current Oracle deployment of Web Conferencing is running a mixture of Linux, Solaris, and HP-UX... soon to be all Linux.

Web conferencing and proxy

Hi,
is there an option to define a proxy while using beehive web conferencing? I don't see this option in the conferencing.cfg.
Thanks,
Stephane.

Well, I am still right in what I'm saying :) : the question has not been labelled "external attendees access" or "is HTTPS tunneling available" !
If you are ready to use a DMZ instance and open some ports, you don't need a proxy to open your web conference server to people on the internet. That's a usage of web conferencing that makes sense.
And more that that, and this is my opinion, considering HTTPS is the
universal solution for network security is a mistake. it's a door open
to anything that's encrypted, and people consider it's safe because of
that. Some engineers invented protocols to make sure that the trafic is
properly identifed, the "all in HTTPS" paradigm is just a denial of
common sense in security ...
Of course, HTTPS tunneling is still a useful option, but not the best IMHO.

Web conferencing issues, thanks

Hi,
I don't know how many of you have done a web conferencing system using JMF. I'm currently working on it but I have addressed some problems. I'd like to hear your suggestions.
The system uses C/S structure and the client uses WebStart. I tried the RTP solutions provided by Sun but I think they are more suitable for P2P.
1. For the video transmission, I capture the camera every 0.5 minute and save to JPEG photos. Then the photos are uploaded to the server. All the other member clients in the conference room download the photos and restore them into a movie. But in this solution there is time delay. Any better ones?
2. For the audio transmission, I have no idea how to do it...
3. Is it better to use a streaming server? I mean, what is the normal architecture for this kind of system? I've installed Darwin Streaming Server but I can't find a way to communicate with it via JMF. If there are some existing solutions, can you please give me the links or sample code?
4. I find that it looks like flash is more popular is this area. Is it possible to use flash in my Java client side? I read the document of Red5 but looks like the client is mainly web page.
Sorry I know I have too many questions here. I have done the research for almost two weeks but still get blocked. So I hope you can help me out here. Thanks in advance!

The system uses C/S structure and the client uses WebStart. I tried the RTP solutions provided by Sun but I think they are more suitable for P2P.You can certainly use RTP for a client-to-server application. It's suitable for any kind of transport.
1. For the video transmission, I capture the camera every 0.5 minute and save to JPEG photos. Then the photos are uploaded to the server. All the other member clients in the conference room download the photos and restore them into a movie. But in this solution there is time delay. Any better ones?You stream the video via RTP to a server, and that server uses the incoming stream as the source for outgoing streams to all of the participants of the video conference...
2. For the audio transmission, I have no idea how to do it...My proposal for #1 handles audio as well.
3. Is it better to use a streaming server? I mean, what is the normal architecture for this kind of system? I've installed Darwin Streaming Server but I can't find a way to communicate with it via JMF. If there are some existing solutions, can you please give me the links or sample code?You do need a streaming server, but you can easily write your own for this application. It's what I like to call a "bounce server" because it just bounces the stream to whoever wants to see it.
4. I find that it looks like flash is more popular is this area. Is it possible to use flash in my Java client side? I read the document of Red5 but looks like the client is mainly web page.Ummmm, no. Red5 is a good freeware Flash Media Server that's capable of doing this video conference application. Adobe Flex is a free API you can use to develope desktop applications or web applications (and thus you would have a Flash-based application that would be running outside of a web browser, transmitting the A/V to the Red5/Flash Media server)

Application doesn't update in web conferencing

I tried to share a graphics application, ProductView, in Web Conferencing. It worked at first, but the graphics portion does not update at the shared sites.
This product probably uses Open/GL to display its graphics. Is there a limitation in Web Conferencing application sharing?
David

The problem was I forgot to include one of the .jar files in the .jnlp file. The application started but immediately finished because it couldn�t find the second jar. Java console has the same behavior and this is why I couldn�t see the message in the console.
Thank you anyway!

BEx Variable in Webi Report questions

Hi Gurus,
Here is my issue.
I created a BEx Query 0SD_C03 Cube with following fields
Two Columns
One Key Figure: Subtotal1
One Restricted Key Figure: Subtotal with restriction " Sales Organization 1000"
Two Rows Plant, Sales Organization
One Variable with Sales Organization.
When I ran this query in BEx Analyzer I can see all Sales Organization values in prompt list, How ever when I created a Universe and ran a webi query I can see 1000 in the Sales Organization list.
Is this because I have restricted Key Figure with Sales Organization 1000 in the query?
I removed my Restricted Key Figure from my query and tried again this time I see some 10 Sales Oraganizations but I didn't see all available Sales Organizations. Does BO Universe LOVs restricte the list?
Thanks
Sasi

Identical entry so this is being closed:

Problems with Java and Web conferencing

I need to use a Web conferencing system that does not require a download. I tried using one that uses Java but several of my clients had problems because their JVM was not compatible or they did not have a JVM installed. Is there a Web conferencing system with no download that does not require Java?

The GoMeetNow system has a mode they call Universal Attendance � there is no requirement of any download whatsoever. This will sure do the job for you.

Web Conferencing

A user receives the following error after clicking on the link "Web Conferences" on the OCS Portal Page: ... "Internal Error.: OID connection misconfigured or other error detected. Please notify the system administrator. Click Login Again to access the application or click Contact Us to inform us of the problem you are experiencing." ....
However, if the user logs in using a different computer, he can login to the Web Conferencing application without any problems. The two computers that are involved in this scenario are set up identical, yet, one fails and the other is successful.
Hope that someone can give me some idea of what I am overlooking in the set up of the failing computer.
Thank you.
New OCS Admin in Michigan.

I suspect that the difference between the two computers is the network access. I think that the computer that is failing does not either have external (internet) or does not have direct access to the middle tier.
The parameter ApacheGlobalWebHost in the imeeting server should have the main url for middle tier or Load Balancer. The ApacheWebhost should have the Middle tier url as this is the url that you are being redirected to. If the second computer does not have direct access to that server then you would encounter this issue.
Also remember you have to have access to the infrastructure to be able to sign in and sso has to be setup properly to be able to access the imeeting application. This may be another cause of this issue.
Try the url http://hostname:port/imtapp/app/prelogin.uix
If you are still having a problem open a SR to Support and have them diagnose the issue.
It is a place to start looking. ;)

Web Conferencing Using JTAPI - Need help

Hi,
I have to work on "Web Conferencing" application, but i don't have any idea how this can be done in Java.
I heard that, JTAPI can be used for this purpose.
Please tell me anyone, is it possible to do Conferencing type of application using JTAPI.
If so what are the Requirements for that?
Do we need to use any specific kind of telephone devices??+
Give me some idea how to begin with this, and any source where i can get all the details about this.
Thanks for any help.....
Thanks,

Take a look at the SIP servlet projects such as Sailfin if you want to deal with traditional PSTN.

Necessary ports for Web Conferencing in Oracle Collaboration Suite

Hi everybody!
What ports are necessary for opening to ensure the functioning with Web Conferencing in Oracle Collaboration Suite 10g (on a computer of the client and a server)
Thanks a lot for your helps.

Hi,
If it's all configured properly on the server, you'll only need whatever port is configured for SSL on the middletier webserver (standard is 443) for actually running the conference - the web application used for scheduling etc. might use a different port but would usually be the same in a well configured environment.

Richard

Lync 2010 : Using same FQDN and IP address for SIP access Edge, Web Conferencing Edge, A/V Edge

Hi Friends,
Please assist on below query.
Will it possible to use the same FQDN in Lync Edge? Since it has different Port numbers for each service, one public IP for all FQDN for access will save me purchasing multiple Certificates for SANs
FQDN
IP Address
Port
Map to
Sip.domain.com
12.34.34.34
5061 (TLS)
SIP Access Edge
Sip.domain.com
12.34.34.34
444(TLS
Web Conferencing Edge
Sip.domain.com
12.34.34.34
443(TCP
A/V Edge
I have a wildcard SSL purchased already and for this purpose I need to purchase more certificates per SAN if unique FQDN required.
Thank You.

Yes, although a wildcard entry only will not work entirely for all Lync clients and versions.
I would suggest something like this:
Edge External
CN: sip.domain.com
SAN: sip.domain.com, webconf.domain.com
Reverse Proxy Listener(s)
CN: lyncwebexternal.domain.com
SAN: lyncwebexternal.domain.com, *.domain.com
The wilcard entrty can replace the SimpleURLs (meet, dialin) but some clients (like any Lync Phone Edition devices prior to the June 2012 firmware) do not support wildcard entries so providing the external web services FQDN is required. also never
put the wildcard etry in the Common Name as devices/client that do not support wildcard entries may be tripped up there and then never even look at the SAN field.
A cheaper alternative (although not typically recommended, this does work) would be to use a single certificate for both servers, like this:
Edge/RP Combo Cert
CN: sip.domain.com
SAN: sip.domain.com, webconf.domain.com, lyncwebexternal.domain.com, *.domain.com

Web Conferencing Compatibility service not installed on Lync 2013

Hi I recently deployed Lync 2013 and have moved a handful of users. I’ve noticed that the Web Conferencing Compatibility service is not listed in my list of services. I have enabled
Web Conferencing in the Topology; the Web conferencing service itself is there. I can telnet to port 8057 but obviously not to 8058. Without this I’m guessing users on Lync 2010 cannot connect to a web conference hosted on the new pool (once simple URLs are
updated to point to the new Front-End). Can anyone advise why it may not have been installed and a suggest a solution; maybe it could be rectified by re-running the Lync Server Components install from the Deployment Wizard?
Thanks.

Hi shoc86,
Most of the problems are removed by updating the software so first i recommend you to update the app. even
after that the problem is not resolved u can contact the Microsoft Customer Care

Web Conferencing Console

O.k. I can't believe this isn't on forum or in Metalink.
Just got Web Conferencing up and so far have had 2 users unable to install the client console piece. I've gone through security settings and all that. They can install on their systems, so that shouldn't be a problem. Basically, everything the "New User" test recommends for that failing seems o.k. One is XP and the other W2k, buy my laptop is XP and it works.
Any ideas?

If the other pcs that cannot donload the client are on the same network then your can ignore the informaiton below.
The problem that you are experiencing sounds to be a firewall issue on the remote site. This is common and is worked around by enabling https tunnelling on your web conferencing server. You will probably notice that the customers that are connecting successfully, to your web conferencing server may not be behind a firewall that only has ports 80 and 443 open.
Port 80 is the default http port and every company has this port open if they are on the internet. Port 443 is the default port for any https (SSL) communication and this also should be open on every companies firewall or they would not be able to view secured sites.
So how do you enable https tunnelling on your web conferencing server?
You will need to review the online documentation.
http://download-east.oracle.com/docs/cd/B12203_01/webconf.904/b10877/toc.htm
Oracle® Web Conferencing Administrator's Guide
Release 2 (2.0.4)
Part Number B10877-01
5.6 Configuring Ports and Network Connectivity
This chapter will describe how to enable mod_imeeting. This is the module that will allow users to connect to your web conferencing server even if they are behind a secure remote firewall.
If you have any problems configuring https tunnelling you should open a TAR and have Oracle Support Services assist you in making https tunnelling work for you .

Web Conferencing on a Mac

I have scoured the documents, forums, etc. and cannot find a definitive answer. Is Web Conferencing on a MAC supported in the lastest version of OCS?
Thanks,
Catherine

I have an Macbook Pro (Intel) machine. I tried using it with Safari but it gives an error that the browser is not supported. It requires Netscape of IE. IE is not available or supported on X Tiger, so Netscape was the only option. There are many issues using Netscape with any Java Applet on Mac, so I decided to try Opera which works fine with most Java Applets because it has IE and Netscape emulation and comes with Java support built in. With Opera, the Applet starts to load then gives an error RCC something. Short answer, it seems Windows is a must.
