Next Page Ruby provides two levels of access to network services. At a low level, you can access the basic socket support in the underlying operating system, which allows you to implement clients and servers for both connection-oriented and connectionless protocols.
Introduction Welcome to the official Infinispan user guide. This comprehensive document will guide you through every last detail of Infinispan.
Because of this, it can be a poor starting point if you are new to Infinispan. For newbies, starting with the Getting Started Guide or one of the Quickstarts is probably a better bet. The Frequently Asked Questions and Glossary are also useful documents to have alongside this user guide.
As a local cache The primary use for Infinispan is to provide a fast in-memory cache of frequently accessed data.
Suppose you have a slow data source database, web service, text file, etc: Using Infinispan is better than using a simple ConcurrentHashMap, since it has additional useful features such as expiration and eviction. As a clustering building block for your applications If you need to make your application cluster-aware, integrate Infinispan and get access to features like topology change notifications, cluster communication and clustered execution.
As a geographical backup for your data Infinispan supports replication between clusters, allowing you to backup your data across geographically remote sites. While they share some methods and properties, be aware that there are semantic differences between them.
The following chapters focus mostly on the embedded implementation. For details on the remote implementation refer to Hot Rod Java Client. CacheManagers are heavyweight objects, and we foresee no more than one CacheManager being used per JVM unless specific setups require more than one; but either way, this would be a minimal and finite number of instances.
The simplest way to create a CacheManager is: CacheManagers have a lifecycle and the default constructors also call start. Overloaded versions of the constructors are available, that do not start the CacheManager, although keep in mind that CacheManagers need to be started before they can be used to create Cache instances.
Once constructed, CacheManagers should be made available to any component that require to interact with it via some form of application-wide scope such as JNDI, a ServletContext or via some other mechanism such as an IoC container.
When you are done with a CacheManager, you must stop it so that it can release its resources: If the CacheManager was clustered it will also leave the cluster gracefully.
Configuration Infinispan offers both declarative and programmatic configuration. Configuring caches declaratively Declarative configuration comes in a form of XML document that adheres to a provided Infinispan configuration XML schema.
Every aspect of Infinispan that can be configured declaratively can also be configured programmatically. In fact, declarative configuration, behind the scenes, invokes the programmatic configuration API as the XML configuration file is being processed. One can even use a combination of these approaches.
For example, you can read static XML configuration files and at runtime programmatically tune that same configuration.
Or you can use a certain static configuration defined in XML as a starting point or template for defining additional configurations in runtime.
There are two main configuration abstractions in Infinispan: Global configuration Global configuration defines global settings shared among all cache instances created by a single EmbeddedCacheManager.Search the world's information, including webpages, images, videos and more.
Google has many special features to help you find exactly what you're looking for. A Simple Client. Here we will write a very simple client program, which will open a connection to a given port and given host. Ruby class TCPSocket provides open function to open such a socket..
The urbanagricultureinitiative.com(hosname, port) opens a TCP connection to hostname on the port.. Once you have a socket open, you can read from it like any IO object. May 12, · Bigmac T.

There are gazillion other protocols for transferring files expect FTP. For example, you can use HTTP. Write a .
A file descriptor is just a number which is used to reference an open I/O channel, like stdout (standard output), a network socket or a file.
When the OS receives a TCP/IP packet it looks at the destination port & tries to find a process which is listening on this port.
yield socket and client address for each a connection accepted via given sockets. The arguments are a list of sockets. The individual argument should be a socket or an array of sockets.
