Clustering in QVS 9 requires a specific license, is easily configured and works in two modes; "Random" and "Document Load".

Random is what it sounds like; clients get put on a random node within the cluster when requesting a document. The document will load on the node where the client will land, which means it will probably be loaded at several nodes.

Document Load will load each document once in the whole cluster. If the document is not loaded when the client requests it, the cluster will load the document at the node with the most free memory. All clients requesting this document will then always go to this node for this document.

Hi Stefan,

How do you set the different modes for clustering? From the QEMC or do you have to go into the config.xml?

best regards,

In Qlikview 10 you can either do this in the QEMC under Web Services or in the webservice config.xml under ProgramData.

See the server reference manual under Server->Clustering/Load Balancing for exact info.

Hi Stefan,

I have been testing the clustering with 2 QVS in both QV9 and QV10 and it doesn't work in that way.

In QV9 SR6 I cannot restart the QVWS with the option "Document Load", I suppose it is not able to recognize this option.

I just can work with "Random" but despite it should load just one qvw document in a random qvs, and after forward any request of this document to the server where it is already loaded, this is not working in this way either. I can see at least 2 qvw loaded in any QVS.

In QV10 I tried to configure the QVWS with the "LoadedDocument" option but it happens the same, I can see the same document loaded in both QVS.

any suggestion? what can I be doing wrong?

Thanks a lot
