Question

我正在连接到GridGain Cluster并且我在日志中看到以下错误，我也注意到客户端连接频繁丢弃/重新连接（虽然对于平台来说是新手，但我不确定这是否是正常行为）。

[12：41：35,548] [WARN] [grid-nio-worker-0-＃53％null％] [GridTcpRestProtocol]没有为NIO会话定义的编组器，使用PROTOBUF作为默认值[ses = GridSelectorNioSessionImpl [selectorIdx = 0 ，queueSize = 0，writeBuf = null，readBuf = null，super = GridNioSessionImpl [locAddr = / 10.25.220.83:11211,rmtAddr = / 1.144.94.10：49000，createTime = 1398948095537，closeTime = 0，bytesSent = 0，bytesRcvd = 1455 ，sndSchedTime = 1398948095537，lastSndTime = 1398948095537，lastRcvTime = 1398948095548，readsPaused = false，filterChain = FilterChain [filters = [GridNioCodecFilter [parser = GridTcpRestParser [jdkMarshaller = GridJdkMarshaller []，protobufMarshaller = org.gridgain.client.marshaller.protobuf.GridClientProtobufMarshaller @ 68ebf23e]，directMode = false]，accepted = true]]]

这是配置问题吗？如何定义编组器？以下是我的配置：

我正在使用C＃4.5控制台应用程序中的以下客户端代码。

static void Main(string[] args)
{

    // Create a GridGain Client
    var ggClient = CreateClient();
    Console.WriteLine("GridGain Connected");

    ggCache = ggClient.Data("partitioned");
    ggCompute = ggClient.Compute();

    ggCache.Put<string, byte[]>("test", new byte[] { 0, 1, 2, 3, 4 });   

    GridClientFactory.StopAll(); 
}

private static IGridClientData ggCache;
private static IGridClientCompute ggCompute;  

/**
 * <summary>
 * This method will create a client with default configuration. Note that this method expects that
 * first node will bind rest binary protocol on default port. It also expects that partitioned cache is
 * configured in grid.</summary>
 *
 * <returns>Client instance.</returns>
 * <exception cref="GridClientException">If client could not be created.</exception>
 */
private static IGridClient CreateClient()
{
    var cacheCfg = new GridClientDataConfiguration();

    // Set remote cache name.
    cacheCfg.Name = "partitioned";

    // Set client partitioned affinity for this cache.
    cacheCfg.Affinity = new GridClientPartitionAffinity();

    var cfg = new GridClientConfiguration();
    cfg.IsTopologyCacheEnabled = true;
    cfg.DataConfigurations.Add(cacheCfg);

    // Point client to a local node. Note that this server is only used
    // for initial connection. After having established initial connection
    // client will make decisions which grid node to use based on collocation
    // with key affinity or load balancing.
    cfg.Servers.Add("127.0.0.1" + ':' + GridClientConfiguration.DefaultTcpPort);
    cfg.Routers.Add("127.1.0.1" + ':' + GridClientConfiguration.DefaultTcpPort);
    // cfg.Servers.Add("127.2.0.1" + ':' + GridClientConfiguration.DefaultTcpPort);

    var client = GridClientFactory.Start(cfg); 
    return client;

}

从GridGain版本6.2.0-rc2开始，GridGain添加了Portable Object功能，该功能显着增强了C ++和.NET功能并修复了连接问题。

使用Portable Objects，您可以：

将对象存储在.NET中并使用Java或C ++进行检索（反之亦然）
动态更改客户端的类结构，而无需重新启动服务器。
从缓存中检索可移植对象而不反序列化到类中，并按名称获取所需的字段。

便携式对象的示例可用于企业版下载。
