jboss - org.jboss.remoting3.ProtocolException : Too many channels open. 如何增加 channel

Question

我有 ejb 客户端连接 jboss 6.4 eap 服务器。每次进行 ejb 调用时，我都会关闭 ejb 上下文。一切正常，但当有大量请求时，我收到“org.jboss.remoting3.ProtocolException:打开的 channel 过多”

            Properties properties = new Properties();
            properties.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
            properties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
            properties.put("remote.connections", "1");
            properties.put("remote.connection.1.host","IP");
            properties.put("remote.connection.1.port","4447");
            properties.put("org.jboss.ejb.client.scoped.context", "true");
            properties.put("remote.connection.1.username", "EJB_USER"));
            properties.put("remote.connection.1.password", "EJB_PASSWORD");


            context = new InitialContext(properties);
            ejbContext = (Context) context.lookup("ejb:");
            final Object obj = ejbContext.lookup("EAR/BEAN/BEANName!RemoteInterface");

            try{
                //do something
            }finally{
                ejbContext.close();
            }

我怎样才能增加这个 channel ？(我怎么知道同时限制为 40 个 channel )

谢谢。

Answer 1

无法增加 channel 数量。我已将我的上下文实例设为静态。
