Virtual classroom using Stratus?

Can Stratus be used in a virtual classroom envrionment with a flash-based whiteboard, screen sharing etc? If not, is it possible to run audio-video over Stratus and - in parallel - run the virtual classroom components over Flash Media Server?
Thanks

I've made a collaboration application that demonstrates all the principles you would need to build your own flash based virtual classroom using only stratus (and a peer sharing app/site). http://www.murphysean.com/?p=37
I'll break it down a little bit:
The whiteboard could be drawn by sending continuosly the mouse position to all the other peers, and the state of the mouse position (is it drawing, perhaps a color)
The audio/video is basically built into flash for you, minus aec (Audio Echo Cancellation) because adobe is not sharing their proprietary tech with the community... See here I demonstrate sharing audio/video/chat/and file sharing (which could be implemented better)
You could also buy into the adobe service LCCS which provides everything you are talking about in an api.

Need an professional FMS developer to build a virtual classroom urgently

hi there, i need a professional developer to build a virtual classroom using FMS. the pay is lucrative , if u can or know any who can, plz email me to [email protected]

You can read my initial view of the i7 17" Quad Core here: http://www.markc.me.uk/MarkC/Blog/Entries/2011/2/25Early_2011_MacbookPro.html
The unit supports SATA 3 & SATA 6: http://grab.by/9adG
I have a 240Gb SSD and a 1Tb normal hard drive in place of the SuperDrive. It's a great solution - personally I'd sort an SSD myself rather than buy Apple's.
Swapping out the SuperDrive does void you warranty as far as I know.
I run virtualised Win7 x64 all day every day and it's ace.

Virtual Classroom Not Found

I have recently upgraded to Conenct 9 and it looks like all is fine apart from if I try to create a Virtual Classroom. I can click on Virtual Classroom from the Home tab and it takes me to the page where it asks to Enter Virtual Classroom Information. I enter the details and when I click Next or Finish I get a screen saying Not Found and The selected resource does not exist. Any ideas?

I think I have resolved the issue it appears the Virtual Classroom default template may have become corrupt. I created a new template and tried using that one and it has worked successfully

Create a virtual classroom via Adobe Connect 9 Web Services

Is it possible to create a virtual classroom via Adobe Connect 9 Web Services? I could not find a way in "Using Adobe Connect 9 Web Services" documentation.

The answer of Jorma Jenning is almost correct. I investigated it myself and finally made a working solution.
The trick is that virtual classroom does not have a special type, instead it is a "meeting inside trainings folder with the icon of virtual-classroom". Kinda strange logic and to add another level of hell the "trainings folder" is the one with the type "my-courses", so, finally, we get the the following workflow:
1. Call h-ttps://example.com/api/xml?action=sco-shortcuts and filter sco-s until you find one with the type="my-courses" and remember its sco-id — this will be your folder-id.
2. call h-ttps://example.com/api/xml?action=sco-update&type=meeting&icon=virtual-classroom&name=October All Hands Meeting
&folder-id=2006258750&date-begin=2006-10-01T09:00
&date-end=2006-10-01T17:00&url-path=october
The thing with icon is important.
Note that if you call report-my-training service immediately after sco-update you won't see this virtual-classroom. This is because the default permissions do not allow that. Add yourself to the user list via permissions-update and it will appear in your training list. This is different from creating virtual classroom from web interface as there you are added as a host by default.

Is there a way to create a virtual network using C# and the Azure SDK/API?

I don't see a clear way to create an Azure Virtual Network using the SDK.
I have all the methods to create the virtual network configuration, but no way to submit it:
IList<string> VirtualNetworkAddressPrefixes = new List<string>();
IList<string> LocalNetworkAddressPrefixes = new List<string>();
IList<NetworkListResponse.DnsServer> DNSServers = new List<NetworkListResponse.DnsServer>();
IList<NetworkListResponse.Subnet> Subnets = new List<NetworkListResponse.Subnet>();
NetworkListResponse.Gateway Gateway = new NetworkListResponse.Gateway();
IList<NetworkListResponse.LocalNetworkSite> LocalSites = new List<NetworkListResponse.LocalNetworkSite>();
IList<NetworkListResponse.Connection> Connections = new List<NetworkListResponse.Connection>();
VirtualNetworkAddressPrefixes.Add("a.b.c.d/cidr");
DNSServers.Add(new NetworkListResponse.DnsServer() { Name = "TestDNS1", Address = "a.b.c.d" });
Subnets.Add(new NetworkListResponse.Subnet() { Name = "Subnet-1", AddressPrefix = "a.b.c.d/cidr" });
Subnets.Add(new NetworkListResponse.Subnet() { Name = "GatewaySubnet", AddressPrefix = "a.b.c.d/cidr" });
Connections.Add(new NetworkListResponse.Connection() { Type = LocalNetworkConnectionType.IPSecurity });
LocalNetworkAddressPrefixes.Add("a.b.c.d/cidr");
LocalSites.Add(new NetworkListResponse.LocalNetworkSite()
Name = "On-Prem",
Connections = Connections,
VpnGatewayAddress = "a.b.c.d",
AddressSpace = new NetworkListResponse.AddressSpace() { AddressPrefixes = LocalNetworkAddressPrefixes }
Gateway.Sites = LocalSites;
Gateway.Profile = GatewayProfile.ExtraLarge;
NetworkManagementClient netMgmtClient = new NetworkManagementClient(CloudCredentials);
NetworkListResponse netlistresp = GlobalSettings.mainWindow.netMgmtClient.Networks.List();
netlistresp.VirtualNetworkSites
.Add(new NetworkListResponse.VirtualNetworkSite()
Name = "TestVirtualNetwork",
AddressSpace = new NetworkListResponse.AddressSpace() { AddressPrefixes = VirtualNetworkAddressPrefixes },
DnsServers = DNSServers,
Subnets = Subnets,
AffinityGroup = "East US",
Gateway = Gateway,
Label = "LabelValue"
I have also created the entire XML response and sent it to the NetworkManagementClient -> Networks.SetConfiguration() method, but it appears this command expects the virtual network to already be in existence. If anyone could give guidance, it would be
appreciated.

Hi,
As discuss above , we have to create the XML response ,before that first you have to
GetConfiguration() details of existing virtual network.
string.format("@<NetworkConfiguration xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://schemas.microsoft.com/ServiceHosting/2011/07/NetworkConfiguration'>

Can multiple Virtual Devices use the same IVI Driver Sessions?

I am using Switch Executive 2.0 and I'm having problems creating multiple Virtual Devices.
I have created a virtual device on a development computer that has no hardware connected to it. This virtual device uses specific drivers to simulate the devices. The problem I'm having is that when I create a second virtual device and try to add the same IVI Switches as the first Virtual device, I'm getting the following error:
An error has occurred while attempting to access the device deviceA_ivi.
Error -223116 occurred:
Internal Software error occurred in Switches software. Please contact National Instruments Support.
File name: .\source\mxsWrappers\tMXSObject.cpp
Line Number 192:
Status Code: -223116
Can someone please explain why?

Can you please elaborate on how did you create those simulated devices? Namely, what does your IVI configuration look like? What does the driver session for the logical name look like? What's the software module? What's the hardware module? What is the driver setup string, and what is the simulation mode for the device in question?

How to set up different virtual LANs (using the E3200)?

Hi.
I would like to set up different virtual LANs (using the E3200) so that I can have two different networks that can't access each other.
The E3200 is connected to a modem for internet access.
I would like both networks to have access to the internet.
Does the E3200 alone support creating virtual LANs?
If not, is there another way I can meet the requirement using the E3200 alone (using something other than virtual LANs)?
I'm ultimately thinking that I would need at least one other router.
So for example,
Router A (E3200) is connected to the modem and setup for DHCP using a LAN IP range 192.168.1.1/24.
Router B is connected to Router A and setup for DHCP using a LAN IP range 192.168.2.1/24.
In this way devices connected to Router A should not have access to devices connected to Router B and visa-versa, correct? For example, Device X connected to Router A cannot ping or browse files on Device Y connected to Router B and visa-versa, correct?
Would I need to setup anything else on Router B? For example, do I need to setup DNS settings so that devices connected to Router B can connect to the internet without issue? Would I need to specify that these virtual LANs are not bridged, and on which router, or both?
I already know how to set up a static IP, DHCP, LAN IP ranges, and static DNS settings on a router, etc.
In regards to wireless devices, I am thinking they would follow the same pattern; so wireless devices connected to Router A (E3200) have access to other wired and wireless devices connected to Router A but not to wired or wireless devices connected to Router B and visa-versa. However, if wireless devices currently don't have access to wired devices also connected to Router A, then that is fine for now.
Thank you very much!
-Rami
Solved!
Go to Solution.

The E3200 has no VLAN support according to the manual. There's no way to configure two separate networks with this router alone.
You will need to add network electronics.
Ex:
Managed Switch with VLAN
Another wireless router with VLAN
If your modem supplies multiple public or private IP addresses then you could put a switch after the modem and two wireless routers attached to the switch.

Having trouble with creation of a cloud service with multiple virtual machines using java sdk.

I am creating a cloud service on azure with 2 virtual machines using java sdk API. Service created successfully.
My input endpoint details are as follows.
INPUT ENDPOINTS
Head : 191.238.144.47:2400
Head : 191.238.144.47:22
Node0 : 191.238.144.47:43211
For Head instance port 2400 is for HTTPS and port 22 is for SSH and for Node0 instance port 43211 is for SSH.
But I am having problem with doing a ssh on Head instance. Sometimes it works sometimes doesn't. Same problem with HTTPS also.
I have some application running over there but when i try to access it thru browser sometimes it works but most of the time doesn't. When I restart the instances from azure portal, its works after
that(not always but most of the time).
Now I am confused what is going on there. I am creating cloud service and virtual machines using java sdk and setting input endpoints also. After creation of all instances i restart every instance programmatically .
I am not sure whether restart is required or not. It must be something to do with input endpoints only but not able to get the right thing i guess. When i do the same thing thru azure portal(creation of cloud service with virtual machines and setting up input
end points) everything works fine but not achieving the result when implementing it by java sdk API. Please help me.

HI Nithin,
Thanks for your reply. I am setting the endpoints after creating my instances using update call. Here's the code snippet.
AzureService aServ = new AzureService(session);
if(aServ.checkNameAvailability(clusterName)) {
aServ.createHostedService(clusterName, "dbX cluster");
// Creating head instance
aServ.createHead(clusterName, imgName, headType, userName, pswd);
// Setting end points for head node
String name = "ssh";
int port = 22;
aServ.updateVMInputEndpoint(clusterName, "Head", name, port);
// Restarting head instance
aServ.restartVM(clusterName, "Head");
String roleName = "Node";
String tmpRoleName = "";
for(int i=0; i<noi; i++) {
port = 43210+(i+1);
tmpRoleName = roleName + i;
// Creating node instance
aServ.createVM(clusterName, tmpRoleName, imgName, nodeType, userName, pswd);
// Setting end points for node instance
aServ.updateVMInputEndpoint(clusterName, tmpRoleName, name, port);
// Restarting node instance
aServ.restartVM(clusterName, tmpRoleName);
// Method to update the input endpoint details
public void updateVMInputEndpoint(String clusterName, String vmName, String name, int port)
throws Exception {
VirtualMachineGetResponse resp = computeManagementClient.getVirtualMachinesOperations().
get(clusterName, clusterName, vmName);
VirtualMachineUpdateParameters updateParameters = new VirtualMachineUpdateParameters();
//get the configuration list
ArrayList<ConfigurationSet> configlist = resp.getConfigurationSets();
//get inputendpoint list and update it
ArrayList<InputEndpoint> endpointlist = configlist.get(0).getInputEndpoints();
InputEndpoint inputEndpoint = new InputEndpoint();
inputEndpoint.setEnableDirectServerReturn(false);
inputEndpoint.setPort(port);
inputEndpoint.setLocalPort(port);
inputEndpoint.setName(name);
inputEndpoint.setProtocol(InputEndpointTransportProtocol.TCP);
endpointlist.add(inputEndpoint);
// Open port for https on head node
if(vmName.equals("Head")) {
inputEndpoint = new InputEndpoint();
inputEndpoint.setEnableDirectServerReturn(false);
inputEndpoint.setPort(2400);
inputEndpoint.setLocalPort(2400);
inputEndpoint.setName("https");
inputEndpoint.setProtocol(InputEndpointTransportProtocol.TCP);
endpointlist.add(inputEndpoint);
updateParameters.setConfigurationSets(configlist);
//required for update
OSVirtualHardDisk osVirtualHardDisk = resp.getOSVirtualHardDisk();
updateParameters.setOSVirtualHardDisk(osVirtualHardDisk);
updateParameters.setRoleName(resp.getRoleName());
OperationResponse updtResp = computeManagementClient.getVirtualMachinesOperations().update(clusterName, clusterName, resp.getRoleName(), updateParameters);
And every time i am creating a new cloud service along with head and node instances. Region is "South Central US".
I am setting ProvisionGuestAgent field to true at instance creation time. Thank you.

CFMX 6.1's Virtual Memory Use problem!!

I appologise for the long post in advance...
Ok... so I have this script that, using cfdirectory, will
check a directory for any files that may have been uploaded, if
there are files, it loops through the results and reads the files
one at a time, line by line, using the FileReader.cfc (Uses the
Java FileInputStream, InputStreamReader, and BufferedReader to
provide a way to incrementally read large files). The files are
just pipe "|" delimited data, each line represents a record for a
db table.
Now as it's reading each line, it will perform some basic
string parsing to clean up the file line to make sure the data is
valid, blah blah blah and then it will write that "cleaned" line to
another file using FileWriter.cfc (Java component once again). Once
it's completely done reading the original file, it will close it
and it will open the new "cleaned" version of the file, read it
(FileReader.cfc), create an INSERT statement and then update the
database table.
Now... this all works GREAT... until it has to loop through
more than a few files... 3 - 4 files are NO problem! works like a
charm, but throw 6 - 8 files at it and it dies, not a timeout mind
you but an actual "java.lang.OutOfMemoryError" (now, I've tried
making all the files exactly the same (just changed the name) and
the weird thing is, it takes longer and longer to process each as
it goes through the loop... I have the script write some stats as
it's looping:
FILE 1 STATS
Name: COA0607_Intranet1.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 74,237ms
FILE 2 STATS
Name: COA0607_Intranet2.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 82,018ms
FILE 3 STATS
Name: COA0607_Intranet3.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 94,476ms
FILE 4 STATS
Name: COA0607_Intranet4.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 145,108ms
I know what you guy are probably thinking; "Woah man... CF
isn't really meant to do that kind of processing...", I know, trust
me I know... however, I really neeeeeed it too lol.
Ok, so as the script is running, I watch the Virtual Memory
use of jrun.exe, processing say 3 - 4 of these files brings up the
usage to approx 300,000k which yes, is a LOT but that's fine...
this process is meant to run at night via a Scheduled Task...
When I run more than 4 files, things start to get ugly, keep
in mind that these are EXACTLY the same files just re-named
differently. The script will start lagging BIG time and on the last
file (usually the last file) I'll see the memory usage spike from
350,000K all the way up to 600,000K and that's when it throws the
"java.lang.OutOfMemoryError" and dies... I've tried commenting out
the part of the script that updates the db, but still get the same
problem...
So... what gives? How come CF Server does this??? I mean, it
runs fine for the first few files... and then WAM, it dies... sorry
for the long post... any insight here is VERY much appreciated...
it would be AWESOME if the wonderful folks at Adobe could shed some
light on this for me : )

Looks like it is "incremental" only in the sense that it increments

Well I did try cffile originally... and it didn't even run...

Java.lang.NullPointerException while creating virtual classroom via Adobe Connect 9 Web Services

Hello all, I am trying to create a virtual classroom via Adobe Connect 9 Web Services with the code below.

</status>
</results>
What could be the reason of this problem? I need your help.

Hi Teomanx
To create a virtual classroom, you have to give type=meeting & icon = virtual-classroom. So the correct syntax is :
https://XXXXXXXX.adobeconnect.com/api/xml?action=sco-update&type=meeting&icon=virtual-clas sroom&name=My Virtual Classroom&folder-id=1358451232&date-begin=2014-01-02T10:00&date-end=2 014-01-02T11:00.
Hope that helps.

Can the boot camp partition be resized once windows is installed and running as virtual machine using vm fusion ware?

I have macbook air partitioned 505/50 and running OSX and win 7 side by side as virtual machines using vm fusion. Can the partition size be changed without starting over?

Very helpful. I started with vm ware to create a pseudo drive but could not import win 7 over home network. mac has no immediate way to connect to network without adapter, and has no cdrom. So i used boot camp to create partition, then made a bootable win7 iso file on a memory stick using win 7 usb/cdrom download tool from microsoft, and rEFIT to get mac to boot from the mem stick into the dos partition. Then i ran vm fusion to import the win 7 partition as a virtual machine. OSx and win 7 run side by side.
Seems from what you say that sizing cannot be accomplished without deleting partition and starting over. If I start over and just run vm fusion to create he win7 virtual machine, not sure how I would bet the minimum win 7 os into the ac. Perhaps vm will boot from the mem stick using refit. Do you know?
