RavenDB cancellation task exception when creating indexes

Question

I'm having a problem creating indexes on RavenDB 3.5

When you create more than 3 indexes, the application simply dies, getting

Unable to connect to the remote server. Status Code: ConnectFailure

The index creation code is straightforward:

private static void CreateIndexes(IDocumentStore documentStore) { new PurchaseOrder_QueryByExternalReference().Execute(documentStore); new SupplierDocument_QueryBySupplierName().Execute(documentStore); new ProductDocument_QueryByProductIdAndName().Execute(documentStore); new PurchaseOrderLine_QueryableIndex().Execute(documentStore); new PurchaseOrderLine_ForPurchaseOrderIndex().Execute(documentStore); } 

But the same thing happens if

IndexCreation.CreateIndexes (typeof (MyIndexClass). Build, save);

Method called

. This happens with any 3 indexes from the list in any order.

The full stack trace is as follows:

Answer 1

In my case, this turned out to be due to a mismatch between the ravendb client library and the installed server. The latest version of the RavenDB client was installed in my application, and version 3.0 is used on the server

Answer 2

When RavenDB 3.5 was released, something broke in the client package.

If you use RavenDB.Client from 3.0.30000 to 3.0.30179, then it should work.

If you use a higher version, then you will encounter (under certain conditions) this exception. To solve this problem, you can use an alternative API : store.DatabaseCommands.PutIndexes .

 var indexes = new List<AbstractIndexCreationTask>(); indexes.Add(new MyIndex1()); indexes.Add(new MyIndex2()); indexes.Add(new MyIndex....()); var transfos = new List<AbstractTransformerCreationTask>(); transfos.Add(new MyTransformer1()); transfos.Add(new MyTransformer2()); transfos.Add(new MyTransformer...()); // put indexes in 1 command var indexesToPut = IndexCreation.CreateIndexesToAdd(indexes, documentStore.Conventions); documentStore.DatabaseCommands.PutIndexes(indexesToPut); // don't forget transformers foreach (var item in transfos) { item.Execute(Store); } 

This should solve your problem.

I ran into this problem after updating my client package. Please note that the exception occurred only in console applications and not in my web applications.

Answer 3

This solved the problem for me:

 var indexes = IndexCreation.CreateIndexesToAdd(new List<AbstractIndexCreationTask> {...}, store.Conventions); var alreadyExisting = store.DatabaseCommands.GetIndexes(0, 128) .ToDictionary(i => i.Name); foreach (var index in indexes.Where(i => !alreadyExisting.ContainsKey(i.Name))) store.DatabaseCommands.PutIndex(index.Name, index.Definition); store.DatabaseCommands.PutIndexes(indexes);
