    Multicast with installation?

    Rookie

      Hi Good Morning,

       

           I'm having a problem using the delivery method "Multicast". It is successfull in pushing the package on the unit, on smdcache. but there was no installtion.

       

      Does "Multicast method", only push the package? and no installation??

       

      We are using landesk 8.8 and trying to push SAP patches. But we are currently testing Winrar with Multicast Method.

       

       

      Thanks,

          Yes, multicast does only push. Multicast helps to target devices not directly from the core but from delegate devices at your network. so the "heavy" package will not "overload" your network.

            Hi Dimitri,

             

            Thanks for the response dimitry, I just thought it will also install the packages.

             

            So its main purpose is to deploy the package on the unit, and make the unit a multicast representative, and then we need to create a new task that will install the package. Instead of the client downloading the package from the core, it will pull the package from the multicast representative.

             

            ^ is my statement above correct?

             

             

            Thanks,

            Joe

              Yes, if you multi-cast a file it will live in the sdmcache on all clients for 2 days and on the domain reps for 14 days (default).

               

              If you were then to follow up the job with a different method (download to local cache) the client will see if it is in its own cache, if so, run it from there, if not, check other systems on same subnet (peers) and get from there, if not, go back to the core or preferred server and get from there.

               

               

              Depending on your network you may or may not even want to use multi-cast... We have over 12,000 systems on one site (but 7 different cores) and a decent network, in all but the rarest cases we just use download to local source (cache) and have not had issues.

                Hi Good Morning,

                 

                Thanks thanks this will be a big help in our software distribution.

                 

                just to clarify, I can download the installer on the client and save it on the folder "C:\Program Files\Landesk\LDclient\sdmcache\installer" and when I push another schedule task, it can detect the installer that I manually add on the client and then install it??

                 

                Thanks,

                Joe

                  Hi Joe.

                   

                  Yes, you are correct.  Once a client successfully downloads the file it will be stored in that local systems cache and advertise it to other clients on the same subnet so they can then copy it to their local cache and then install it.

                   

                  Good luck.

                    Hi Good Morning guys,

                     

                    Thanks for the quick responses..

                     

                    last question,

                     

                    Regarding the installer that I have manually placed on the client. will it be automatically deleted as stated by James? even thought the installer has been manually downloaded and not deployed by multicast?

                      Edit...

                       

                      Just re-read your post.  If you are MANUALLY copying the files to the SDMCache folder, the LANDesk Client WILL NOT advertise it to other clients, by default.  There is a "trick" to tell the client that those files are there, so it can advertise it, but I don't remember what that trick is.

                        Hi Spike,

                         

                             Can you tell me the trick?

                         

                        Thanks,

                          I think that if you stop the Targeted Multicast Service on the client you are copying the files to, copy the files to the sdmcache folder, and then restart the service.

                           

                          If I am right, you should be able to check the "HKEY_LOCAL_MACHINE\SOFTWARE\Intel\LANDesk\LDWM\Distribution\Multicast\Cache Files" registry key and see a list of the file(s) you added.

                            Joe,

                             

                            Please clarify what you mean when you say "manually" placed the file....

                             

                             

                            How did you get the file there?

                              Hi James,

                                  

                                   What to Install on the workstations: SAP patch 15 (130MB)

                                   Where is the installer: Core Server

                                   Distribution Method: Software Deployment Portal

                                  

                                  Here is our situation, Im in our head office where the core server is located. There would be no problem deploying/Installting SAP over Local area network, bandwidth would not be an issue.

                               

                                   We have another office (Lets call it Office B). The bandwidth that is connecting head office to Office B is 128KB. If I deploy the package on Office B it would take some time (lets say this would take about 3 hours), but after that, other workstations in Office B will pull the package on the unit that has the package. So this is good.

                               

                                  What if I want to do is Copy the Installer on the Core Server, then go to Office B which would only take 30 minutes, then paste the installer on sdmcache.

                              Then Ill create a task using policy method. When the user click deploy on SDP,  would the workstations on Office B recognize that installer, and pull that installer on that workstation instead on the core server?

                               

                              If ever this is possible how lond will the installer stay on sdmcache?

                               

                              Spike is suggesting that its possible just restart the service.

                               

                              Thanks,

                                Joe,

                                 

                                I do not know enough about the sdmcache process to answer about manually copying items into the sdmcache and if they get "registered" as being there or not, it is something you will have to test I guess.

                                 

                                Also, something I am not sure of is, how the subfolder path of the sdmcache folder might affect this....  If you test "cache" this on your box, you will see that sub -folder(s) get created according to the path of the share location... again, I am not sure if this matters or not... but to be safe I would copy the sub-folder and all folders and files inside of it from your test box on your network to a client at Site B

                                 

                                I would then restart the service as mentioned and test....

                                 

                                Ty or others will know more about this
