    <p>I`m trying to test netty, but when i creating a multiple clients to connect to server, some of client just froze and never finish. Here my code( basically i used code from her <a href="https://github.com/brunodecarvalho/netty-tutorials" rel="nofollow noreferrer">https://github.com/brunodecarvalho/netty-tutorials</a> and just modify it to use a several clients):</p> <pre><code> for (int i = numthr; i > 0; i--) { Runnable runner = new Runnable() { public void run() { final Client client = new Client("localhost", 10400, nummes, 0); if (!client.start()) { System.exit(-1); return; } client.flood(); Runtime.getRuntime().addShutdownHook(new Thread() { @Override public void run() { client.stop(); } }); } }; executor.execute(runner); } </code></pre> <pre><code> public void messageReceived(Envelope message) { if (this.received.incrementAndGet() == this.messages) { System.out.println(nmb.incrementAndGet()); } } public boolean start() { // For production scenarios, use limited sized thread pools this.clientFactory = new NioClientSocketChannelFactory(Executors.newCachedThreadPool(), Executors.newCachedThreadPool(),1); this.channelGroup = new DefaultChannelGroup(this + "-channelGroup"); this.handler = new ClientHandler(this, this.channelGroup); ChannelPipelineFactory pipelineFactory = new ChannelPipelineFactory() { @Override public ChannelPipeline getPipeline() throws Exception { ChannelPipeline pipeline = Channels.pipeline(); pipeline.addLast("encoder", new Encoder()); pipeline.addLast("decoder", new Decoder()); pipeline.addLast("handler", handler); return pipeline; } }; ClientBootstrap bootstrap = new ClientBootstrap(this.clientFactory); bootstrap.setOption("reuseAddress", true); bootstrap.setOption("tcpNoDelay", true); bootstrap.setOption("keepAlive", true); bootstrap.setPipelineFactory(pipelineFactory); boolean connected = bootstrap.connect(new InetSocketAddress(host, port)).awaitUninterruptibly().isSuccess(); if (!connected) { this.stop(); } return connected; } </code></pre> <pre><code> this.serverFactory = new NioServerSocketChannelFactory(Executors.newCachedThreadPool(), Executors.newCachedThreadPool()); this.channelGroup = new DefaultChannelGroup(this + "-channelGroup"); ExecutionHandler executionHandler = new ExecutionHandler( new MemoryAwareThreadPoolExecutor(270, 1048576, 1048576)); ServerBootstrap bootstrap = new ServerBootstrap(this.serverFactory); bootstrap.setPipelineFactory( new DatabaseGatewayPipelineFactory(executionHandler)); bootstrap.setOption("reuseAddress", true); bootstrap.setOption("child.tcpNoDelay", true); bootstrap.setOption("child.keepAlive", true); bootstrap.setOption("child.connectTimeoutMillis", 10000); Channel channel = bootstrap.bind(new InetSocketAddress(this.host, this.port)); if (!channel.isBound()) { this.stop(); return false; } this.channelGroup.add(channel); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
