我在尝试在RavenDB 3.5上创建索引时遇到问题

当创建3个以上的索引时，应用程序就会死掉，得到一个

  

无法连接到远程服务器状态代码：ConnectFailure

索引创建代码非常简单：

    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);
    }

但如果

，也会发生同样的情况
  

IndexCreation.CreateIndexes（typeof（MyIndexClass）.Assembly，store）;

调用

方法。任何订单上的列表中的任何3个索引都会发生这种情况。

完整堆栈跟踪是这样的：

答案 0 :(得分：4)

当RavenDB 3.5发布时，客户端软件包中出现了一些问题。

如果您从3.0.30000到3.0.30179运行RavenDB.Client，那么它应该可以正常工作。

如果您运行的是更高版本，则会遇到（在某些情况下）此异常。要解决此问题，您可以使用alternate 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);
}

这可以解决您的问题。

升级客户端软件包后遇到此问题。请注意，异常仅发生在控制台应用程序中，而不是在我的Web应用程序中。

这解决了我的问题：

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);

在我的情况下，结果是由于ravendb客户端库和已安装的服务器不匹配。我的应用程序运行的是最新版本的RavenDB客户端，服务器使用的是版本3.0
