In two previous entries I covered Introducing NIO.2 (JSR 203) Part 1: What are new features? and Introducing NIO.2 (JSR 203) Part 2: The Basics In this entry I will discuss Attributes introduced in NIO.2. Using attributes we can read platform specific attributes of an element in the file system. For example to hide a file system in DOS file system or to check the last access date of a file in a UNIX machine.
The Pensieve - Masoud Kalali's Blog
My personla blog where I share notes and thoughts about software technology landscape. Covering subjects ranging from tech strategy, leadership, software architecture, cloud native, and software development in general.
Introduction In this chapter we will cover fault and services administration and management. The fault management mostly deals with failing hardware components while service management and administration deals with software failures. A hardware failure is a faulty RAM module and a sample of failing service component is an HTTP server stopped functioning properly. OpenSolaris is an enterprise operating system meaning that it should be resilient to both software and hardware failures and automatically recover from the failure and repair itself or in cases when it is not possible for the OS to repair and recover, it should notify some administrator to take action.
In this part we will discuss the basic classes that we will work with them to have file system operations like copying a file, dealing with symbolic links, deleting a file, and so on. I will write a separate entry to introduce classes which are new to Java 7 for dealing with streams and file contents, watching service and directory tree walking. If you want to know what are new features in Java SE 7 for dealing with IO take a look at Introducing NIO.
I will write a series of blog to discuss what are the new features introduced in NIO.2 (JSR 203). The NIO.2 implementation is a part of OpenJDK project and we can alreay use it by downloading a copy of OpenJDK binary. In the first entry I will just go through what are these new I/O features of Java 7, which help developer iron out better applications easier. Talking about File systems support and features which let us deal with file system we can name the following features:
Introduction ZFS pools provide us with the underlying storage with which we can create files and directories inside it right after we create it. But OpenSolaris and ZFS provides more than that by introducing ZFS datasets… In this recipe we will work on top of a zfs pool named fpool and the default root pool named rpool. So before continuing on this recipe we should have a pool named fpool created.
