Unable to open access point - no server

[paul_ripley]

Hello

We have a common problem.  When I copy an app on the server from one folder to another, or sometimes even just closing a report on the server, the copy takes a long time like half an hour or when i close an app i get not 'responding'.

I'm not sure if there is a process running that prevents me from saving qvw. When a qvw runs does it prevent you from saving on the server?

Has anyone experienced issues like this

Many thanks

Paul

this site helped me to get rid of the "No Server" Error.

Paul, I just want to clarify what you are doing, as I am not sure I am understanding correctly, but I think you are talking about the Desktop Client from what I can gather and in your case server means running the client on the server, not that you are accessing things through the QlikView Server and the Accesspoint?  I want to be sure I am correctly following you here, so if you can clarify a bit further, I can likely come up with some ideas, but I want to be sure I am understanding you properly first.  My assumption is when you say copying, you are using a Windows File Explorer session to do the copy and when you mentioned opening the app, you were talking about in the Desktop Client and doing a SaveAs to save it to the other folder?

Hi Brett

The issue seems to occur as you say when I am developing apps and for example using windows explorer to copy a file from a Dev folder to a Live folder.  The copy 'gets stuck' and seems to hang.  Whilst this is happening we lose access to the Access Point and no one can open any apps. 

After a certain length of time the copy finishes and we get can the open the access point and all is ok

Thanks

Paul

Paul, ok, thanks for the confirmation on things, that helps quite a bit.  If the QVW you are copying is pretty large, that may explain things along with the fact if there are users active in that particular application, they would definitely be 'frozen' until the update completes, as the server has to swap the existing version of the app out of memory and then load the new version into memory.  Publisher handles things a bit more gracefully than what you are doing.  The only way of which I can think to do things a bit more efficiently, would be to put things in another folder close to where you are ultimately putting it and then RDP into the server and open a Windows Explorer to copy folder to folder there, given things are on the same partition, the copy should be much quicker I would expect.  

What version are you running, need the full xx.xx.xxxxx?  The thing I am having trouble explaining is why everyone gets hung up here, things should really only impact those users that are in the app being updated...  It would seem there is something else in play, which is why I want the version info, as that may help explain things further depending upon what that is.  Sorry I do not have anything better for the moment.

Thanks Brett

One of the things that we have been asked to do is change the disk from dynamic to fixed.  I will see how that goes.

Hey Paul, I assume you mean virtual machine setup?  If so, agree 110% with that recommendation, as we need the resource immediately, the VM cannot allocate things quickly enough before things will fail.  This is important for memory and CPU resources as well, it is best to allocate the resources upfront when the VM starts up...  You want the VM to mimic a physical machine basically.  Lots of IT folks treat us like a file server instead of a SQL Server where the latter is the better comparison as to how things need to be configured.  Just shout if that does not do the trick for you.
