pooling

问题 I'm trying to implement this description and that what I did I generated uni_gram & bi_gram & tri_gram of shape(?,15,512) "using padding " & then for each word I concatenate the three feature vector (?,3,512) and then I apply to them Globalmaxpooling1D I do not know if I implemented it well or not so can any one help me ? Q = Input(shape=(15,)) V = Input(shape=(512,196)) word_level = Embedding ( vocab_size , 512 , input_length=max_length)(Q) uni_gram = Conv1D( 512 , kernel_size = 1 ,

问题 Could please somebody tell me a real life example where it's convenient to use this factory method rather than others? newSingleThreadExecutor public static ExecutorService newSingleThreadExecutor() Creates an Executor that uses a single worker thread operating off an unbounded queue. (Note however that if this single thread terminates due to a failure during execution prior to shutdown, a new one will take its place if needed to execute subsequent tasks.) Tasks are guaranteed to execute

问题 My dB connections are constantly timing out. I looked through some of the solutions people have offered to this, and have implemented them, but nothing has worked out till now. Any new thoughts, will be very helpful. Problem For some requests to the webapp, this is the error I am getting : com.mysql.jdbc.CommunicationsException: The last packet successfully received from the server was 11,198,881 milliseconds ago. The last packet sent successfully to the server was 11,198,881 milliseconds ago

问题 Like we can get the number of busy connection in c3p0 by using method like dataSource.getNumBusyConnections() , the same way how can we do that in case of hikaricp? Can anyone provide all the related methods between c3p0 and hikaricp? Also what is the destroy (in c3p0) method equivalent in hikaricp? 回答1: Re: connections, see these wiki pages: JMX Monitoring (via console and programatically Using Codahale/Dropwizard Metrics HikariDataSource supports both close() and shutdown() methods, they

问题 i'm building a web application and i want to use "Connection Pooling" because of the benefits that came with it. I read some tutorials but i really don't understand what i need to do. If someone could give me a north, i appreciate. I'm using JSP/Servlet, MySQL, Tomcat 6 and Netbeans 6.9.1. Best regards, Valter Henrique. 回答1: Have you read http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html#MySQL_DBCP_Example? It shows you all the steps to access your database from a

问题 I have a GenericKeyedObjectPool in my application. I can close it with the close method but how should I wait for the clients to return (and the pool destroys) every borrowed object to the pool? I need something like ExecutorService.awaitTermination. 回答1: Create a wrapper for the GenericKeyedObjectPool which has the required awaitTermination method. You can check the close and the returnObject calls and decrement a latch if the pool is closed and every object was returned (= the total number

问题 I'm looking to make heavy consumption of a RESTful API from a ColdFusion application. I'm not a CF expert but I'm anticipating the repeated cfhttp calls will become a bottleneck as I believe that each results in a connection being established, request sent, response received and connection torn down. I'm curious - is there a way to maintain a connection pool that requests could be sent through to avoid the repeated establish/tear down? Does the ColdFusion server provide such a facility that I

问题 Is it really worth pooling WCF proxy clients, or is it better to instanciate a new proxy on every call to a given method? By the way, does anyone have a pooling pattern for this kind of proxies which he/she is willing to share? 回答1: It is worth to cache ChannelFactory because its construction is costly. Proxies generated by Add Service Reference (or svcutil.exe directly) do this in some scenarios (generally you must not build binding in code if you want to have this caching). If you build

问题 Like the title says, is there a way to "reuse" a SessionFactory for multiple databases? Since instantiating the SessionFactory takes time, I wonder if it would be possible to pool these instances and reuse them, changing only the connection/database name. Obviously, first level cache would be cleared, but I am trying to avoid the penalty involved in instantiating the factory itself. The background is that I can have several small "pluggable" databases with exactly the same schema, so there is

问题 I'm following this tutorial regarding how to pool objects in Spring. I've followed the instruction written on the tutorial but when I run my application, it always generates a new instance of the object. I'm expecting that since I'm pooling the objects, existing objects will be reuse. As such, no new instances should be created. Also, when I access of the getter method of the bean, a new instance of the bean is created again. What could have I done wrong? Did I misunderstood the concept of
