Virtual Cache with VMware View

This issue has been solved. See solution.

Dear All,

I would like to provide Virtual cache with our View desktops for our users. They should be able to archive mails conviently using drag and drop in Outlook. We use Personas management and roam the vault cache with the profiles too. But I want to restrict the cache size of Vault and set OVstoresize to 1GB. I think this is enought cache for the headers. 

I had recently an experience myself when I wanted to archive mails remotely with a View deskop. I archived over 300 items with drag and drop and wanted to synchronize it with the server. The connection was dropped after a while.

I noticed then the current cache size was 1GB and the maximum cache size was 1GB too. I quit Outlook and went to registry and changed the OVstoresize to 2GB. After this change items to archive were processed.

This calls for some questions.

- Is the current cache size full won't EV synch with the server anymore?

- I thought EV has an intelligent management and will reorganize the cache to make space for new items?

We use the httponly client version 9.0.2.

Thank you,

Edy

Can you reproduce any or all of this NOT using a thin client?

Sorry, i should add..  I can *try* to reproduce it, but it will take me a little while to generate enough data :)

It is difficult to reproduce it. The virtual cache on the server is set to 50% of free space on the hard drive.

I deleted the cache on the thin client and re-created it. I set the maximum cache size to 1GB and it seems to work now. But the current cache size is just around 250MB. I guess the real test starts when the cache size is equal to the maximum cahce size.

Is there a knowldege base article how VV cache works in a ideal world once the current and maximum cache size are equal?

Thanks,

Edy

There is a Virtual Vault white paper, but I'm not sure it covers what happens when the limits are reached and you try to manually synch some copied in data.

Okay thanks - I think I need to find the answer for it somewhere

Edyxx's picture

Thank you! This is an excellent blog. What I suffer now is that it starts synchronzing for a while and then it fails. But I think this is a different issue.

Also I want to mention that I don't have admin access to the Vault server.

Fails.... without what sort of message either on screen, or in the client trace?

Have you tried building it up, and letting just 10 items be archived by VV?  Is the issue when there are hundreds of items? Or particularly big items?  Or anything like that?

Edyxx's picture

If I archive one or two items it does synchronize. Uploading to the server seems to be fine.

But my current cache size is around 300MB of 1 GB now. So there would be space left to download more items from the server. But this don't happen. The connection is green for a while and then it break to red.

But it could be something with the roaming profile and local folder. I have to watch it over the next several days.

Thanks,

Edy

Are you looking at that 300 Mb as the total size of all the files in the Vault Cache folder? eg MDC, and .db files etc?

Edyxx's picture

Please see attached file. At the moment it does archive when I drag some items (3) to VV. The MDC file is 304MB.

I thought it would download items from the server until the 1GB maximum cache size is reached. It doesn't do that. The headers are complete and I can with useing easy search in Outlook searching the archive as well. When I open a items from searching which is in EV the items in cache increase.

It looks like at the moment everything is working perfect. Let us see how it works once the currenct cache size reached the maximum cache size. According to your tests it should work.

Thank you very much for your contribution. Very helpful.

Okay.. so what is showing me is that it downloaded the MDC file ...  of about 304 Mb, and that it has just under 65000 items TO download..  It hasn't downloaded any of them though.

 

The 3 in your cache, I would suggest are the ones you dragged and dropped in, and then did 1-2 synchronisations afterwards.

 

So the issue is as it says ..  'Download failed'.

 

Please check ON DISK what files you have and post a screenshot.  If you want to know which folder to look in, look in your client log file for the setting shown below:

 

 

31/08/2012 18:31:37.325[2480][H]: [Offline Config] Root Directory: C:\Users\rob\AppData\Local\KVS\Enterprise Vault\
31/08/2012 18:31:37.329[2480][H]: [Offline Config] Working Directory: C:\Users\rob\AppData\Local\KVS\Enterprise Vault\8FCDB71E2E42DC448BDB5A95B3BA2505\
 
Look in the second of those folders, and show hidden files, post a screenshot.
 
I would suggest here that the issue is that the items either aren't getting put in to a .DB file on the server (ready to download to your client) or that they are .. but then the download to the client is failing.
 
To troubleshoot this first of all look on the EV server properties in the Vault Admin Console, and check if the server has a cache location specified.  If it doesn't, it'll need that added.  If it does, then have a look in that folder, and look in the VCBuilds folder.  Do you have files there?

Please see attached a screesnhot of my folder what files I have.

In the meantime I have archived more items. They do get synchronized (uploaded) to the server, but nothing is downloaded. The files I archived newly in my View desktop are shown in the items in  cache.

Do I guess correctly there is an issue with the server and my EV mailbox? I'm not a EV admin and I do only have limited access to the console.

Thanks, 

Edy

Yes.  Your next port of call would be to check if the .db files are in fact being built on the EV server.  On the properties of the server, a 'cache' location is specified.  The .db files will be built in there.  So you can see if there is any..  what state they are in etc.

 

You could also test that BITS is working correctly from your client - I blogged about how to do that some time ago, so have a look if you decide to go down that route.
